[0005] The present invention aims to provide a slot machine with improved control during transition to an advantageous zone. [Means for solving the problem]

[0006] The slot machine of claim 1 comprises: A variable display unit (reels 2L, 2C, 2R) capable of variably displaying a plurality of types of identification information that can be individually identified, A slot machine (slot machine 1) in which a display result is derived by stopping the variable display of the variable display unit, and a winning prize can be generated according to the display result, A section control means is provided that can control a section to either a normal section that is not controlled to an advantageous state (AT state) or an advantageous section that can be controlled to the advantageous state (AT state), The advantageous zone includes a normal state, and a first specific state (CZ4 state) and a second specific state (CZ3 state) that are more likely to transition to the advantageous state (AT state) than the normal state, The first specific state (CZ4 state) is a state that is more likely to transition to the advantageous state (AT state) than the second specific state (CZ3 state), It is possible to perform a first control of terminating the advantageous zone and transitioning to the normal zone after the advantageous state (AT4 state) has ended, and controlling to the first specific state (CZ4 state) when transitioning to the advantageous zone again; a second control of controlling to the first specific state (CZ4 state) while continuing the advantageous zone after the advantageous state (AT4 state) has ended; and a third control of controlling to the second specific state (CZ3 state) while continuing the advantageous zone after the advantageous state (AT3 state) has ended. When the first control is performed to control to the first specific state (CZ4 state), a preparation performance (standby performance) is performed when the normal section is entered; In the case of controlling to the first specific state (CZ4 state) in the second control, after the advantageous state (AT4 state) ends, the first specific state (CZ4 state) is controlled via a preparation performance state (preparation state) in which the preparation performance (standby performance) is performed, In the case of controlling to the second specific state (CZ3 state) in the third control, after the advantageous state (AT3 state) ends, control to the second specific state (CZ3 state) without going through the preparation performance state (preparation state), It is possible to control external signals (CZ AT signal, AT signal) that can be output to the outside of the slot machine during the advantageous period to an ON state, When controlling to the first specific state (CZ4 state) in the first control, the external signals (CZ AT signal, AT signal) are temporarily turned off when the advantageous state (AT4 state) ends, and are turned on after the transition to the first specific state (CZ4 state); When controlling to the first specific state (CZ4 state) in the second control, the external signal (CZ·AT signal, AT signal) is temporarily turned off when the advantageous state (AT4 state) ends, and is turned off for at least one game, and then turned on after the transition to the first specific state (CZ4 state). It is characterized by the following. According to this feature, when the second control is controlled to the first specific state while the advantageous zone continues, the first control is controlled to the first specific state through a preparatory performance in the same manner as when the first control is controlled to the first specific state after the advantageous zone ends once, making it difficult to distinguish whether the advantageous zone continues to be controlled to the first specific state while the advantageous zone continues, or the advantageous zone ends once and the first specific state is controlled. On the other hand, when the third control is controlled to the second specific state while the advantageous zone continues, the third control can transition to the second specific state quickly after the advantageous state ends.

The presentation mode of the specific state (CZ2 state) controlled when the advantageous period is ended and the advantageous period is entered again is selected based on the game history (the number of consecutive AT2 times) in the advantageous period that has ended. It is characterized by the following. According to this feature, after the advantageous state ends, the advantageous zone is ended and the normal zone is entered, and when the advantageous zone is entered again, control is exercised to enter a specific state, and the presentation mode of the specific state is selected based on the game history in the ended advantageous zone, so that even if the advantageous zone ends, it is possible to make it appear as if the advantageous state up to that point and the subsequent specific state are occurring continuously.

[0011] The slot machine of aspect 1-2 is the slot machine according to aspect 1-1, The presentation mode of the specific state (CZ2 state) controlled when the advantageous period ends and transitions to the advantageous period again is selected based on the history of the advantageous state (the number of consecutive AT2 times) in the advantageous period that has ended. It is characterized by the following. According to this feature, after the advantageous state ends, the advantageous zone is ended and the normal zone is entered, and when the advantageous zone is entered again, control is exercised to enter a specific state, and the presentation mode of the specific state is selected based on the history of the advantageous state in the ended advantageous zone, so that even if the advantageous zone is interrupted, it can be made to appear as if the advantageous state up to that point and the subsequent specific state are occurring continuously.

[0012] The slot machine of aspect 1-3 is the slot machine according to aspect 1-2, Regarding the presentation mode of the specific state (CZ2 state) that is controlled when the advantageous zone is ended and the advantageous zone is entered again, if the period (AT2 consecutive times) during which the advantageous zone is controlled in the advantageous zone (AT2 state) during the ended advantageous zone is a specific period (20 times) or more, a specific presentation mode (CZ2 presentation (ED)) is more likely to be selected than if the period is less than the specific period (20 times). It is characterized by the following. According to this feature, when a favorable state is controlled for a specific period or longer in a favorable section that has ended, a specific presentation mode is likely to be selected, and therefore, by having a specific presentation mode in a specific state, it is possible to make the player recognize that they have been controlled in an advantageous state for a long period of time.

[0013] The slot machine of aspect 1-4 is the slot machine according to any one of aspects 1-1 to 1-3, A pre-determination means (internal lottery) is provided for determining whether or not a prize is to be allowed to occur; The normal zone is transitioned to the advantageous zone according to the determination result (advantageous zone transition role) of the pre-determination means, The presentation mode of the specific state (CZ2 state) that is controlled when the advantageous zone ends and transitions back to the advantageous zone is selected based on the history of the advantageous state in the ended advantageous zone (the number of consecutive AT2 occurrences) and the type of decision result (advantageous zone transition role) of the pre-determination means that triggered the transition back to the advantageous zone. It is characterized by the following. According to this feature, when an advantageous state ends, the advantageous zone is terminated and a transition is made to the normal zone, and then control is made to a specific state when the game transitions again to the advantageous zone, the presentation mode of the specific state is selected based on the history of the advantageous state in the ended advantageous zone and the type of determination result of the pre-determination means that triggered a transition to the advantageous zone again, so that the presentation mode can be selected according to the trigger for transitioning to the advantageous zone.

[0014] The slot machine of aspect 1-5 is the slot machine according to any one of aspects 1-1 to 1-4, The presentation mode of the specific state (CZ2 state) controlled when the advantageous zone is ended and the advantageous zone is entered again is selected based on the history of the advantageous state (the number of consecutive AT2 occurrences) in the ended advantageous zone and whether or not the advantageous state (AT2 state) is controlled after the end of the specific state (CZ2 state). It is characterized by the following. According to this feature, when an advantageous state ends, the advantageous zone ends and the normal zone is entered, and then when the advantageous zone is entered again, control is performed to a specific state, the presentation mode of the specific state is selected based on the history of the advantageous state in the ended advantageous zone and whether or not control is performed to an advantageous state after the end of the specific state, thereby drawing attention to the presentation mode of the specific state.

[0015] The slot machine of aspect 1-6 is the slot machine according to aspect 1-5, A pre-determination means (internal lottery) is provided for determining whether or not a prize is to be allowed to occur; The normal zone is transitioned to the advantageous zone according to the determination result (advantageous zone transition role) of the pre-determination means, A first decision (AT lottery at the time of transition to the advantageous zone) is made to determine whether or not to control to the advantageous state (AT2 state) after the specific state (CZ2 state) depending on the decision result (advantageous zone transition role) of the pre-determination means that triggered the end of the advantageous zone and transition to the advantageous zone again, and a second decision (AT lottery for the CZ2 state) is made to determine whether or not to control to the advantageous state (AT2 state) after the specific state (CZ2 state) depending on the decision result (result of an internal lottery) of the pre-determination means in a specified game (first game) in the specific state (CZ2 state). It is characterized by the following. According to this feature, after the advantageous state ends, when the advantageous zone ends and the normal zone is entered, and when the advantageous zone is entered again, control is exercised to a specific state, the presentation mode of the specific state is selected based on the results of both the first decision at the time of the transition to the advantageous zone and the second decision in a specified game in the specific state, so that the results of both the first decision and the second decision can be reflected in the presentation mode of the specific state.

[0016] The slot machine of aspect 1-7 is the slot machine according to aspect 1-5 or 1-6, Regarding the presentation mode of the specific state (CZ2 state) that is controlled when the advantageous zone is ended and the advantageous zone is entered again, if the advantageous state (AT2 state) is not controlled after the end of the specific state (CZ2 state), the specific presentation mode (CZ2 presentation (ED)) is more likely to be selected than if the advantageous state (AT2 state) is controlled. It is characterized by the following. According to this feature, if the specific state is not controlled to an advantageous state after the specific state, the specific state is likely to be controlled to a specific presentation mode, whereas if the specific state is controlled to an advantageous state, the specific state is unlikely to be controlled to a specific presentation mode, making it possible to give the appearance that advantageous states are occurring continuously.

[0017] [Form 2] The slot machine of type 2-1 is A variable display unit (reels 2L, 2C, 2R) capable of variably displaying a plurality of types of identification information that can be individually identified, A slot machine (slot machine 1) in which a display result is derived by stopping the variable display of the variable display unit, and a winning prize can be generated according to the display result, A section control means is provided that can control a section to either a normal section that is not controlled to an advantageous state (AT state) or an advantageous section that can be controlled to the advantageous state (AT state), The advantageous zone includes a normal state, and a first specific state (CZ4 state) and a second specific state (CZ3 state) that are more likely to transition to the advantageous state (AT state) than the normal state, It is possible to perform a first control of terminating the advantageous zone and transitioning to the normal zone after the advantageous state (AT4 state) has ended, and controlling to the first specific state (CZ4 state) when transitioning to the advantageous zone again; a second control of controlling to the first specific state (CZ4 state) while continuing the advantageous zone after the advantageous state (AT4 state) has ended; and a third control of controlling to the second specific state (CZ3 state) while continuing the advantageous zone after the advantageous state (AT3 state) has ended. When the first control is performed to control to the first specific state (CZ4 state), a preparation performance (standby performance) is performed when the normal section is entered; In the case of controlling to the first specific state (CZ4 state) in the second control, after the advantageous state (AT4 state) ends, the first specific state (CZ4 state) is controlled via a preparation performance state (preparation state) in which the preparation performance (standby performance) is performed, When controlling to the second specific state (CZ3 state) in the third control, after the advantageous state (AT3 state) ends, control to the second specific state (CZ3 state) without going through the preparation performance state (preparation state). It is characterized by the following. According to this feature, when the second control is controlled to the first specific state while the advantageous zone continues, the first control is controlled to the first specific state through a preparatory performance in the same manner as when the first control is controlled to the first specific state after the advantageous zone ends once, making it difficult to distinguish whether the advantageous zone continues to be controlled to the first specific state while the advantageous zone continues, or the advantageous zone ends once and the first specific state is controlled. On the other hand, when the third control is controlled to the second specific state while the advantageous zone continues, the third control can transition to the second specific state quickly after the advantageous state ends.

[0018] The slot machine of aspect 2-2 is the slot machine according to aspect 2-1, The first specific state (CZ4 state) is a state that is more likely to transition to the advantageous state (AT state) than the second specific state (CZ3 state). It is characterized by the following. According to this feature, it is possible to give the player hope that the preparatory performance will result in the player being controlled to an advantageous state.

[0019] The slot machine of aspect 2-3 is the slot machine according to aspect 2-1 or 2-2, The advantageous state (AT state) includes a first advantageous state (AT3 state) and a second advantageous state (AT4 state) in which a greater increase in gaming value can be expected than in the first advantageous state (AT3 state), When controlling from the first specific state (CZ4 state) to the advantageous state (AT state), control to the second advantageous state (AT4 state); When controlling from the second specific state (CZ3 state) to the advantageous state (AT state), control to the first advantageous state (AT3 state). It is characterized by the following. According to this feature, it is possible to anticipate that the preparatory performance will result in control being placed in the more advantageous first advantageous state.

[0020] The slot machine of aspect 2-4 is the slot machine according to aspect 2-3, It is possible to determine that the advantageous state (AT state) is to be controlled when transitioning to the advantageous zone, When it is determined that the advantageous state (AT state) is to be controlled at the time of transition to the advantageous zone, the first advantageous state (AT4 state) is controlled. It is characterized by the following. According to this feature, it is possible to prevent control to an unintended type of advantageous state when transitioning to an advantageous zone during the first control process.

[0021] The slot machine of aspect 2-5 is the slot machine according to any one of aspects 2-1 to 2-4, The expected value of the period during which the semiconductor device is controlled to the first specific state (CZ4 state) is smaller than the expected value of the period during which the semiconductor device is controlled to the second specific state (CZ3 state). It is characterized by the following. According to this feature, even if the game is controlled to the preparation performance state, the period until the game is controlled to the advantageous state does not become excessive.

[0022] The slot machine of aspect 2-6 is the slot machine according to any one of aspects 2-1 to 2-5, A pre-determination means (internal lottery) is provided for determining whether or not a prize is to be allowed to occur; In the normal zone, the game is transferred to the advantageous zone based on the determination result of the pre-determination means being a specific result (a role of transferring to an advantageous zone), In the case where the second control is performed to control to the first specific state (CZ4 state), after the advantageous state ends, the determination result of the pre-determination means becomes a specific result (advantageous zone transition role), and the first specific state (CZ4 state) is controlled based on this. It is characterized by the following. According to this feature, when the second control controls the state to the first specific state while the advantageous zone continues, the state will be controlled to the first specific state at the same trigger as when the first control controls the state to the first specific state after the advantageous zone ends once, making it difficult to determine whether the state was controlled to the first specific state while the advantageous zone continued, or whether the state was controlled to the first specific state after the advantageous zone ended once.

[0023] The slot machine of aspect 2-7 is the slot machine according to any one of aspects 2-1 to 2-6, The game device includes a derivation operation means (stop switches 8L, 8C, 8R) that is operated by a player to derive a display result, In the advantageous section, in a non-advantageous state (normal state, premonition state, CZ1 state, CZ3 state, CZ4 state) that is not controlled to the advantageous state (AT state), when the derivation operation means is operated in a first manner (a stop operation sequence in which the left reel is the first stop) the degree of advantage in transitioning to the advantageous state (AT state) differs from when the derivation operation means is operated in a second manner (a stop operation sequence in which a reel other than the left reel is the first stop) (when playing with a stop operation sequence in which a reel other than the left reel is the first stop, a penalty related to the AT is given); When the second control is performed in the advantageous area, in the preparation performance state (preparation state), the degree of advantage regarding the transition to the advantageous state (AT state) does not change regardless of the manner in which the derivation operation means is operated (even if a game is played in a stop operation order in which a reel other than the left reel is the first stop, no penalty is given in relation to the AT). It is characterized by the following. According to this feature, in the preparatory presentation state when the second control is performed, the degree of advantage regarding transition to the advantageous state does not change regardless of the manner in which the derivation operation means is operated, as in the normal section, making it difficult to determine whether the advantageous section has continued and the control has been made to the first specific state, or whether the advantageous section has ended once and then the control has been made to the first specific state.

[0024] The slot machine of aspect 2-8 is the slot machine according to any one of aspects 2-1 to 2-7, It is possible to control external signals (CZ AT signal, AT signal) that can be output to the outside of the slot machine during the advantageous period to an ON state, When controlling to the first specific state (CZ4 state) in the first control, the external signals (CZ AT signal, AT signal) are temporarily turned off when the advantageous state (AT4 state) ends, and are turned on after the transition to the first specific state (CZ4 state); When controlling to the first specific state (CZ4 state) in the second control, the external signal (CZ·AT signal, AT signal) is temporarily turned off when the advantageous state (AT4 state) ends, and is turned off for at least one game, and then turned on after the transition to the first specific state (CZ4 state). It is characterized by the following. According to this feature, even if the second control is controlled to the first specific state while the advantageous zone continues, the external signal is temporarily turned off, just as in the case where the first control is controlled to the first specific state after the advantageous zone ends once, making it difficult to determine whether the first specific state was controlled to while the advantageous zone continued, or whether the first specific state was controlled after the advantageous zone ended once.

[0025] The slot machine of aspect 2-9 is the slot machine according to any one of aspects 2-1 to 2-8, Equipped with specific light emitting units (LED 19a during CZ / AT, LED 19b during AT) that can be emitted during the advantageous period s, When controlling to the first specific state (CZ4 state) in the first control, the specific light-emitting unit (LED 19a during CZ / AT, LED 19b during AT) is temporarily put into a non-light-emitting state (non-illuminated state) when the advantageous state (AT4 state) ends, and is put into an illuminating state (illuminated state) after transition to the first specific state (CZ4 state); When controlling to the first specific state (CZ4 state) in the second control, the specific light-emitting portion (LED 19a during CZ AT, LED 19b during AT) is temporarily set to a non-light-emitting state (non-illuminated state) when the advantageous state (AT4 state) ends, and after being set to a non-light-emitting state (non-illuminated state) for at least one game, is set to a light-emitting state (illuminated state) after transition to the first specific state (CZ4 state). It is characterized by the following. According to this feature, even if the second control is controlled to the first specific state while the advantageous zone continues, the specific light-emitting unit will temporarily go into a non-light-emitting state, just as in the case where the first control is controlled to the first specific state after the advantageous zone has ended once, making it difficult to determine whether the first specific state was controlled to while the advantageous zone continued, or whether the first specific state was controlled after the advantageous zone ended once.

[0026] The slot machine of aspect 2-10 is the slot machine according to any one of aspects 2-1 to 2-9, The termination condition of the advantageous period includes an upper limit termination condition (termination condition 1) that is established when the gaming value (net increase in number of coins) acquired by the player in the advantageous period exceeds an upper limit amount (upper limit number of coins), When the advantageous state (AT4 state) ends, if the difference (remaining net increase) between the amount of gaming value acquired by the player in the advantageous period (net increase) and the upper limit amount (upper limit number) is equal to or less than a specific amount (specific number), the advantageous period ends. It is characterized by the following. This feature prevents the upper limit end condition of the advantageous zone from being met in the middle of an advantageous state, causing the advantageous state to suddenly end, or the addition being limited so as not to reach the upper limit amount.

[0027] The slot machine of aspect 2-11 is the slot machine according to any one of aspects 2-1 to 2-10, In the case where it is confirmed that the right to control to the advantageous state (AT4 state) is granted in the advantageous state (AT4 state), after the advantageous state (AT4 state) ends, control to the advantageous state (AT4 state) without controlling to the preparation performance state or the first specific state (CZ4 state).

[0032] In this embodiment, the CZ·AT LED 19a and the AT LED 19b are provided separately, but a single LED that lights up to indicate that the CZ·AT signal is on or that the AT signal is on may be used for both. In this case, the LED is turned off when both the CZ·AT signal and the AT signal are off, and turned on when at least one of the CZ·AT signal or the AT signal is on. Then, when both the CZ·AT signal and the AT signal are off, the LED is turned off. With this configuration, the LED is always turned on when either the CZ·AT signal or the AT signal is on, making it possible to confirm that either signal is being output.

[0033] Inside the MAXBET switch 6 is a BET switch valid LED 21 (see Figure 3) which lights up to indicate that the operation of setting the bet amount by operating the MAXBET switch 6 is valid, and inside the stop switches 8L, 8C, 8R are left, middle and right stop valid LEDs 22L, 22C, 22R (see Figure 3) which light up to indicate that the operation of stopping the reels by the corresponding stop switches 8L, 8C, 8R is valid.

[0034] In addition, a liquid crystal display 51 capable of displaying images is provided on the front of the slot machine 1. The liquid crystal display 51 has a liquid crystal panel that is transparent when no voltage is applied to the liquid crystal element, and is provided so that a display area is located in front of the reels 2L, 2C, and 2R of the front door 1b (on the player side). The reels 2L, 2C, and 2R on the rear side of the liquid crystal display 51 can be viewed from the player side through the transparent area corresponding to the see-through window 3 and the see-through window 3 in the display area of ​​the liquid crystal display 51.

[0035] On the inside of the front door 1b of the slot machine 1, there are provided a reset switch 23 which detects a reset operation to release an error state from outside the slot machine 1 by operating a specified key, a setting value display 24 which displays the setting value at that time when the setting value is being changed or checked, a door open detection switch 25 which detects the open state of the front door 1b, a flow path switching solenoid 30 which selectively switches the flow path of the medal inserted from the medal insertion port 4 to either the hopper tank side or the medal payout outlet 9 side which are provided inside the slot machine 1 and will be described later, and a medal selector 29 having inserted medal sensors 31a-31c which detect medals inserted from the medal insertion port 4 and flowing down to the hopper tank side.

[0036] Also provided inside the slot machine 1 are a reel unit 34 for spinning and stopping the aforementioned reels 2L, 2C, and 2R in response to a control signal from the main control unit 41, and a hopper unit 35 for paying out medals from a medal payout outlet 9 in response to a control signal from the main control unit 41.

[0037] Also provided inside the slot machine 1 are a setting key switch 37 for switching between a setting change state and a setting confirmation state, a reset / setting switch 38 which functions as a reset switch for releasing an error state under normal circumstances and which functions as a setting switch for changing the set value of the winning probability (ball payout rate) of the internal lottery described below in the setting change state, and a power switch 39 which is operated to turn the power on and off.

[0038] As shown in FIG. 3, the slot machine 1 is provided with a game control board 40 and a presentation control board 90. The game is controlled by the game control board 40, and the presentation control board 90 controls the presentation according to the game status.

[0039] The game control board 40 is connected to the aforementioned MAXBET switch 6, start switch 7, stop switches 8L, 8C, 8R, settlement switch 10, reset switch 23, inserted medal sensors 31a to 31c, a reel sensor (not shown) of the reel unit 34, a payout sensor and a full tank sensor (not shown) of the hopper unit 35, a setting key switch 37, and a reset / setting switch 38, and detection signals from these connected switches etc. are input.

[0040] In addition, the game control board 40 is connected to the aforementioned credit display 11, game auxiliary display 12, 1-3 BET LEDs 14-16, start valid LED 18, CZ / AT LED 19a, AT LED 19b, replay LED 20, BET switch valid LED 21, left, middle, right stop valid LEDs 22L, 22C, 22R, setting value display 24, flow path switching solenoid 30, reel unit 34, and hopper unit 35, and these electrical components are driven based on the control of the main control unit 41 mounted on the game control board 40 and described later.

[0041] A main control unit 41 that controls games is mounted on the game control board 40. The main control unit 41 includes a ROM 41b in which programs and the like are stored, and a RAM 41c in which work data is temporarily stored.

[0042] In addition, the main control unit 41 transmits various commands to the sub-control unit 91. Commands transmitted from the main control unit 41 to the sub-control unit 91 are sent in only one direction, and no commands are sent from the sub-control unit 91 to the main control unit 41.

[0043] In addition, the main control unit 41 outputs a CZ-AT signal, which can identify that the machine is controlled to either the AT state described below or the CZ state described below, and an AT signal, which can identify that the machine is controlled to the AT state described below, to external hall equipment such as call lamps via an external output board (not shown).

[0044] The performance control board 90 is connected to the aforementioned performance switch 56, and its detection signal is input. In addition, performance devices such as the aforementioned liquid crystal display 51, speakers 53 and 54 capable of outputting sound, and a performance LED 57 capable of changing the light emission state are connected to the performance control board 90, and the output states of these performance devices can be controlled by a sub-controller 91 mounted on the performance control board 90. The sub-controller 91 receives commands sent from the main control unit 41 and detection signals from the performance switch 56, and performs various controls for producing performances.

[0045] The slot machine 1 of this embodiment is configured to change the medal payout rate according to the set value. In detail, the medal payout rate is changed by using the winning probability according to the set value in a lottery that affects the advantage of the player, such as an internal lottery or an AT lottery. The set value has six stages from 1 to 6, with 6 being the highest payout rate, and the payout rate decreasing as the value decreases in the order of 5, 4, 3, 2, and 1. In other words, when 6 is set as the set value, the advantage of the player is the highest, and the advantage decreases step by step as the value decreases in the order of 5, 4, 3, 2, and 1.

[0046] In order to change the set value, it is necessary to turn on the power switch 39 of the slot machine 1 after turning on the setting key switch 37. When the power is turned on with the setting key switch 37 in the ON state, the set value read from the RAM 41c is displayed as a display value on the setting value display 24, and the state transitions to a setting change state in which the set value can be changed by operating the reset / setting switch 38. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated by one (when the reset / setting switch 38 is operated again from the set value 6, it returns to the set value 1). Then, when the start switch 7 is operated, the display value is confirmed as the set value. Then, when the setting key switch 37 is turned off, the confirmed display value (set value) is stored in the RAM 41c of the main control unit 41, and the state transitions to a state in which the game can proceed. In addition, the main control unit 41 initializes the data related to the game stored in the RAM 41c in response to the change in the set value.

[0047] The setting key switch 37 and the reset / setting switch 38 are provided inside the slot machine 1 and cannot be operated unless the front door 1b, which can be opened by a predetermined key operation, is opened, and only staff members of the game arcade in which the slot machine 1 is installed who possess a predetermined key can operate them. In particular, the setting key switch 37 requires a further key operation, and therefore only staff members of the game arcade who possess a key for operating the setting key switch 37 can operate them. The reset switch 23 does not require the front door 1b to be opened, but requires a key operation using a predetermined key, and therefore only staff members who possess the predetermined key can operate them. The reset / setting switch 38 also functions as a reset switch for canceling an error state under normal circumstances.

[0048] When playing a game on the slot machine 1 of this embodiment, first, medals are inserted into the medal insertion section 4, or the MAXBET switch 6 is operated to set the number of bets using credits. When a specified number of bets determined according to the game state is set, a predetermined winning line LN (see FIG. 1, which is set across the symbols arranged in a curved manner in the middle of the reels 2L and 2C and the upper part of the reel 2R in this embodiment) becomes valid, and the operation of the start switch 7 becomes valid, that is, the game can be started. If medals are inserted in excess of the maximum number of the specified number corresponding to the game state, the amount is added to the credits. In this embodiment, only one winning line is applied, but multiple winning lines may be applied.

[0049] In this embodiment, in order to make it easier to recognize that a combination of symbols that constitute a win has been lined up on the win line LN, inactive lines LM1 to LM5 are set in addition to the win line LN. The inactive lines LM1 to LM5 are not used to determine whether a win has been achieved by the combination of symbols that have been lined up on these inactive lines LM1 to LM5, but are configured so that when a combination of symbols that constitute a win has been lined up on the win line LN, a combination of suggestive symbols (e.g., bell a-bell a-bell a) that suggests a win is lined up on one of the inactive lines LM1 to LM5, making it easier to recognize that a combination of symbols that constitute a win has been lined up on the win line LN.

[0050] When the start switch 7 is operated in a state in which the game can be started, each of the reels 2L, 2C, and 2R spins, and the symbols on each of the reels 2L, 2C, and 2R change continuously. When any of the stop switches 8L, 8C, and 8R are operated while the reels 2L, 2C, and 2R are spinning, stop control is performed on the corresponding reel 2L, 2C, and 2R, the spinning of that reel is stopped, and the symbol on that reel is derived and displayed as a display result in the see-through window 3.

[0051] In the stop control, within the maximum stop delay time (190 ms (milliseconds) in this embodiment) from when each stop switch is operated, control is performed to stop the rotation of the reels 2L, 2C, and 2R corresponding to the operation, and up to four frames of symbols can be drawn in before the maximum stop delay time (190 ms) has elapsed. In other words, in the stop control, it is possible to select one symbol from the symbols displayed when the stop switches 8L, 8C, and 8R are operated and the symbols four frames ahead from there, a total of five frames (draw-in range), and to lead it to the reels 2L, 2C, and 2R.

[0052] As a result, in the stop control, when the corresponding stop switches 8L, 8C, 8R for each reel 2L, 2C, 2R are operated to stop the rotation, if the pattern constituting the winning combination that has been won in the internal lottery described below is within a retraction range of up to four frames from the pattern when the stop switch is operated, the pattern is retracted onto the winning line LN and the rotation of the reel for which the stop switch is operated is stopped, while if the pattern constituting the winning combination that has been won in the internal lottery is not within the retraction range, a pattern that does not constitute any winning combination is retracted onto the winning line LN so that the patterns constituting winning combinations that have not been won in the internal lottery do not stop on the winning line LN, and the rotation of the reel for which the stop switch is operated is stopped.

[0053] In addition, in the stop control, when the winning of a special role (BB in this embodiment) accompanied by a transition of the game state is carried over, if a small role accompanied by the award of a medal is won in an internal lottery, and the special role and the small role are simultaneously won, the constituent symbols of the winning small role are controlled to be drawn preferentially to the winning line LN within the above-mentioned drawing range, and when the constituent symbols of the winning small role cannot be drawn to the winning line LN, the constituent symbols of the winning special role are controlled to be drawn to the winning line LN. For this reason, in a game in which a special role and a small role are simultaneously won, it is difficult to make the winning special role win a prize.

[0054] In addition, in the stop control, when the winning of a special role (BB in this embodiment) is carried over, if a replay role with the grant of a replay is won in an internal lottery, and the special role and the replay role are won at the same time, the constituent symbols of the winning replay role are drawn preferentially to the winning line LN. The symbols constituting the replay role on each reel 2L, 2C, and 2R are arranged within a predetermined drawing range, and when the replay role is won, the constituent symbols of the replay role are always drawn to the winning line LN. For this reason, in a game in which a special role and a replay role are won at the same time, the winning special role cannot be made to win.

[0055] Then, one game ends when all reels 2L, 2C, and 2R are stopped, and when a combination of symbols of a predetermined winning combination stops on the winning line LN as a display result on each reel 2L, 2C, and 2R, a win occurs, and control according to the win is performed. When a small combination wins, a number of medals determined according to the type is awarded to the player and added to the credit. When the credit reaches the upper limit (50 in this embodiment), the medals are paid out directly from the medal payout outlet 9 (see FIG. 1). When a replay combination wins, a replay is awarded, which allows the player to play without inserting a medal. When a special combination wins, the game state is shifted to another game state.

[0056] In this embodiment, the game starts when the operation of the start switch 7 is detected while the operation of the start switch 7 is in a valid state, and ends when all the reels have stopped. Also, one unit of control for executing a game (game control) starts when all the controls associated with the end of the previous game are completed, and ends when all the controls associated with the end of the current game are completed.

[0057] In the slot machine 1 of this embodiment, the types of winning combinations (hereinafter referred to as winning combinations) are determined according to the game state, and include a small combination with a medal payout, a replay combination that allows the player to start the next game without setting a bet amount, and a special combination with a transition of the game state. Hereinafter, the small combination and the replay combination are also collectively referred to as a general combination. In order for each combination determined according to the game state to win, it is necessary to win the internal lottery and set the winning flag for that combination. The internal lottery is determined by the main control unit 41 using random numbers to determine whether or not to allow each combination to win before the display results of all reels 2L, 2C, and 2R are derived (specifically, when the operation of the start switch 7 is detected with the specified number of bets set).

[0058] Among the winning flags for each role, the winning flags for the small role and the replay role are only valid in the game in which the flag is set and are invalid in the next game, but the winning flag for the special role is valid until the combination of roles permitted by the flag is completed and is invalid in the game in which the combination of roles permitted by the flag is completed. In other words, once the winning flag for the special role is won, even if the combination of roles permitted by the flag cannot be completed, the winning flag is not invalidated and is carried over to the next game.

[0059] In addition, in the internal lottery, when a stop operation is performed in a predetermined operation mode (for example, a push order, operation timing), a small role or a replay role (hereinafter, sometimes referred to as a navigation target role) that is more advantageous than when a stop operation is performed in another operation mode can be won. The navigation target role includes, for example, a role that becomes a more advantageous stop mode when a stop operation is performed in a predetermined operation mode than a stop mode that stops when a stop operation is performed in another operation mode, and a role that has a higher rate of stopping an advantageous stop mode when a stop operation is performed in a predetermined operation mode than when a stop operation is performed in another operation mode. In addition, an advantageous stop mode includes not only a stop mode accompanied by the awarding of medals, but also a stop mode accompanied by a transition to an advantageous game state, a stop mode in which a transition to an unfavorable game state is avoided, and the like.

[0060] The main control unit 41 can control the game to an assist time (AT) state, which is a notification period during which a navigation notification can be executed, in which navigation information capable of identifying the operation mode of the stop switches 8L, 8C, and 8R that is advantageous to the player is notified by the lighting mode of the game assist display 12 according to the internal lottery result. The main control unit 41 starts controlling the AT state when the right to be controlled in the AT state is granted to the player. Then, when the game is controlled to the AT state, the navigation notification is executed by winning the navigation target role, and the operation mode (e.g., the push order, operation timing, etc.) of the stop switches 8L, 8C, and 8R that is advantageous to the player is notified by the game assist display 12, and a command capable of identifying the operation mode that is advantageous to the player is transmitted to the sub-control unit 91, thereby executing a navigation performance in which the operation mode is notified by the liquid crystal display 51 or the like. By operating the stop switches 8L, 8C, and 8R in the operation mode notified by the navigation notification and the navigation performance, the navigation target role won by the internal lottery can be surely won.

[0061] In this embodiment, the main control unit 41 is equipped with a game auxiliary display 12 capable of displaying the number of medals paid out, error codes, and navigation information, and is configured to notify the navigation information using the game auxiliary display 12 in controlling the navigation notification, but it may also be configured to have a dedicated display capable of displaying only the navigation information, and to notify the navigation information using the dedicated display in controlling the navigation notification.

[0062] [About game status] The main control unit 41 can control the gaming state to any one of non-internal, internal, and special states.

[0063] The non-internal state is a state in which the winning of the special role (BB) is not carried over. In the factory default state of the slot machine 1 or in a state in which the game-related data stored in the RAM 41c is initialized by changing the settings, the slot machine 1 is first controlled to be in the non-internal state. Also, the slot machine 1 is controlled to be in the non-internal state by ending the special state. And, the non-internal state ends when the special role (BB) is won in an internal lottery in the non-internal game, the special role is lost, and the state transitions to the internal state. Also, the non-internal state ends when the special role (BB) wins in a game in which the special role (BB) is won in an internal lottery, and the state transitions to the special state.

[0064] Also, in the non-internal state, by operating the stop switches 8L, 8C, 8R in a game within a predetermined period in an operation manner advantageous to the player, the medal payout rate per game during that period exceeds 100%, whereas by not operating the stop switches 8L, 8C, 8R in an operation manner advantageous to the player, the medal payout rate per game during that period does not exceed 100%. In the non-internal state, by not notifying the player of an operation manner advantageous to the player, the medal payout rate per game does not exceed 100%.

[0065] During the internal draw, the special role (BB) is carried over. The internal draw starts when the special role (BB) is won in the internal draw during the non-internal draw.

[0066] Inside, when stop switches 8L, 8C, 8R are operated in a manner advantageous to the player during a game within a specified period, the medal payout rate per game during that period exceeds 100%, whereas when stop switches 8L, 8C, 8R are not operated in a manner advantageous to the player, the medal payout rate per game during that period does not exceed 100%. During periods when an operation manner advantageous to the player is notified, the medal payout rate per game exceeds 100%, whereas during periods when an operation manner advantageous to the player is not notified, the medal payout rate per game does not exceed 100%.

[0067] The special state is a game state controlled by the winning of a special role (BB), which starts when the special role (BB) is won during a non-internal state, and ends when a predetermined end condition is met (for example, the total number of medals paid out during the special state exceeds a predetermined number (for example, 50 medals)). After the special state ends, the game state transitions to a non-internal state.

[0068] In the slot machine 1 of this embodiment, when in a non-internal state, a special role (BB) is won with a predetermined probability (e.g., approximately 1 / 4.2), and the state transitions to an internal state. Also, when in the internal state, i.e., when the winning flag of the special role (BB) is carried over, if the slot machine is not controlled to the AT state described below, the medal payout rate per game does not exceed 100%, whereas when the slot machine is controlled to the AT state, the medal payout rate per game exceeds 100%.

[0069] In addition, in the reel stop control, if a special role and a small role are won at the same time, the control is made to prioritize the small role, and furthermore, in all small roles that are the subject of the internal lottery, the pull-in range of the configuration symbol of the special role (BB) and the pull-in range of the configuration symbol of the small role overlap, and even if any small role is won, the configuration symbol of the winning small role will stop on the winning line LN. In addition, if a special role and a replay role are won at the same time, the control is made to always align the replay role. In other words, if a small role or a replay role is won inside, the special role (BB) will not win.

[0070] In addition, since any of the small roles or any of the replay roles will always be won while in the internal state, once the state has been transitioned to the internal state, the special role (BB) will not be won, and after the transition to the internal state, the internal state will be maintained.

[0071] For this reason, in the slot machine 1 of this embodiment, since the majority of play is controlled internally, it is assumed that the slot machine 1 is controlled internally, and the medal payout rate corresponding to the set value (1 to 6 in this embodiment) is set to a value determined according to each set value, by setting whether or not to control the slot machine to AT internally, specifically, the probability of winning the internal lottery described below, the probability of transitioning to the AT state, etc.

[0072] In addition, the main control unit 41 can control the AT that notifies the player of the advantageous operation mode (correct pressing order) of the stop switches 8L, 8C, and 8R through a navigation notification while the special role (BB) winning is carried over, and is designed to ensure an appropriate medal payout rate during the period.

[0073] [About the roles eligible for the internal lottery] As shown in FIG. 4, in this embodiment, normal replay, which allows the winning of normal replay accompanied by the award of replay, rare replay, which allows the winning of rare replay accompanied by the award of replay, 12 types of push order roles, which allow the winning of main small role accompanied by the award of 12 medals and sub small role accompanied by the award of 1 medal, rare small role A, which allows the winning of rare small role A accompanied by the award of 1 medal, rare small role B, which allows the winning of rare small role B accompanied by the award of 3 medals, rare small role C, which allows the winning of rare small role C accompanied by the award of 3 medals, and 6 types of push order roles, which allow the winning of main small role accompanied by the award of 12 medals and sub small role accompanied by the award of 1 medal, rare small role B, which allows the winning of rare small role B accompanied by the award of 3 medals, and rare small role C, which allows the winning of rare small role C accompanied by the award of 6 medals. The following may be subject to the internal lottery: rare small role D, which allows the winning of rare small role D with the award of one medal; 1 small role, which allows the winning of 1 small role with the award of one medal; BB, which allows the winning of BB with transition to a special state; BB+rare small role A, which allows the winning of both BB and rare small role A; BB+rare small role B, which allows the winning of both BB and rare small role B; BB+rare small role C, which allows the winning of both BB and rare small role C; BB+rare small role D, which allows the winning of both BB and rare small role D; and BB+1 small role, which allows the winning of both BB and 1 small role.

[0074] During non-internal draws, the following are subject to internal draws: normal replay, rare replay, 16 types of push order roles, BB+rare minor role A, BB+rare minor role B, BB+rare minor role C, BB+rare minor role D, BB+1 minor role, and BB. During non-internal draws, the winning probability of a normal replay is approximately 1 / 7.54, the winning probability of a rare replay is approximately 1 / 228, the winning probability of a push order role is approximately 1 / 1.59 (each winning probability is approximately 1 / 12.7), the winning probability of a BB+rare minor role A is approximately 1 / 8192, the winning probability of a BB+rare minor role B is approximately 1 / 199, the winning probability of a BB+rare minor role C is approximately 1 / 60, the winning probability of a BB+rare minor role D is approximately 1 / 33, the winning probability of a BB+1 minor role is approximately 1 / 5.46, and the winning probability of a BB is approximately 1 / 16384.

[0075] Also, during the internal lottery, the normal replay, rare replay, 16 types of push order roles, rare small role A, rare small role B, rare small role C, rare small role D, and 1-piece small role are the subject of the internal lottery, and roles including special roles are not subject to the internal lottery. During the internal lottery, the winning probability of the normal replay is about 1 / 7.53, the winning probability of the rare replay is about 1 / 228, the winning probability of the push order role is about 1 / 1.59 (the winning probability of each is about 1 / 12.7), the winning probability of the rare small role A is about 1 / 8192, the winning probability of the rare small role B is about 1 / 199, the winning probability of the rare small role C is about 1 / 60, the winning probability of the rare small role D is about 1 / 33, and the winning probability of the 1-piece small role is about 1 / 5.46.

[0076] As described above, the push order role is a role in which multiple small roles (in this embodiment, a main small role and a sub small role) are won, and when the stop operation is performed in the stop operation order corresponding to each push order role (any of the operation orders of center left / right, center right / left, right left center, or right center left), the main small role with the award of 12 medals is won regardless of the timing of the stop operation, while when the stop operation is performed in a stop operation order other than the corresponding stop operation order, the sub small role with the award of one medal is won depending on the timing of the stop operation, or the sub small role is not won, resulting in a loss. In other words, it is a minor role in which the expected value of the number of medals awarded changes depending on the difference in the stop operation order, and the expected value of the number of medals awarded changes when the stop operation order corresponding to each push order role is navigated to.

[0077] In this embodiment, only the stop operation sequence in which the center reel or the right reel is the first stop is assigned as the stop operation sequence of the push order minor role, and by playing with the stop operation sequence in which the center reel or the right reel is the first stop, the medal award rate will increase, but in the normal state, premonition state, CZ1 state, and CZ2 state (CZ3 and CZ4 in Example 2) described later, a penalty is given in relation to the transition to the AT state, and the medal award rate taking into account the transition to the AT state due to the disadvantage is lower than the medal award rate when playing with the stop operation sequence in which the left reel is the first stop. Specifically, if the stop operation is performed with the stop operation sequence in which a reel other than the left reel is the first stop in the normal state and premonition state described later, the number of games completed described later will not be updated, and in the CZ1 state and CZ2 state (CZ3 and CZ4 in Example 2) described later, the AT lottery will not be performed. For this reason, in the normal state, premonition state, CZ1 state, and CZ2 state (CZ3 and CZ4 in the second embodiment) described below, the player is encouraged to play in the stopping operation order with the left reel as the first stop.

[0078] Also, winning numbers 1 to 29 are assigned to normal replay, rare replay, 16 types of push orders, rare minor A, rare minor B, rare minor C, rare minor D, 1-piece minor, BB+rare minor A, BB+rare minor B, BB+rare minor C, BB+rare minor D, BB+1-piece minor, and BB, respectively, and the winning numbers of the winning combinations in the internal lottery are set in the RAM 41c. The winning numbers are assigned values ​​of winning numbers 1 or less for combinations that do not transition to the advantageous zone described later, and winning numbers 2 or more for combinations that transition to the advantageous zone. For this reason, the main control unit 41 does not specify individual winning numbers for whether or not the advantageous zone transition combination has been won in the normal zone, but determines whether or not the winning number is 2 or more, and if the winning number is 2 or more, specifies that the advantageous zone transition combination has been won.

[0079] In addition, a flag category (FC) is assigned to the role that is the subject of the internal lottery, and the flag category (FC) of the role that wins in the internal lottery is set in the RAM 41c. The flag category (FC) is assigned a common value to roles that have common attributes, such as multiple types of push order roles, multiple roles with similar winning probabilities, and roles in which a common role wins. For this reason, when the main control unit 41 performs an AT lottery, which will be described later, and specifies the probability according to the winning role, it does not specify the probability according to the winning role from each winning number, but specifies the probability according to the winning role according to the value of the flag category (FC) assigned to the winning role. This makes it unnecessary to determine the probability for each individual winning number, and it becomes possible to specify the probability according to the attribute of the winning role by determining the probability for each flag category (FC), which is smaller than the winning number.

[0080] [About navigation notifications and navigation effects] The manner of navigation notification performed by the main control unit 41 and the manner of navigation presentation performed by the sub control unit 91 will be described with reference to FIG.

[0081] The main control unit 41 can perform navigation notification to notify the player of a stop mode advantageous to the player according to the navigation target role by displaying a navigation display corresponding to the navigation target role won in an internal lottery on the game auxiliary display 12 during a predetermined game in which processing related to navigation notification is performed (from when the reels start to when all reels stop spinning). Also, the main control unit 41 can transmit a command including a navigation number capable of identifying a stop mode advantageous to the player to the sub-control unit 91 at the start of a predetermined game in which processing related to navigation notification is performed.

[0082] In response to this, in a game in which a stopping pattern advantageous to the player can be identified based on a command received from the main control unit 41, the sub-control unit 91 can use an LCD display 51 or the like to provide a navigation effect to notify the player of the stopping pattern.

[0083] The main control unit 41 performs processing related to navigation notification, and during a game in which "1" is set as the navigation number, the main control unit 41 displays on the game auxiliary display 12 navigation display 1 (display displaying "21" on the game auxiliary display 12) suggesting that the stop mode advantageous to the player is the center, right, left stop operation sequence, and during a game in which "2" is set as the navigation number, the main control unit 41 displays on the game auxiliary display 12 navigation display 2 (display displaying "23" on the game auxiliary display 12) suggesting that the stop mode advantageous to the player is the center, right, left stop operation sequence. During a game in which "3" is set as the navigation number, navigation display 3 (a display that displays "31" on the game auxiliary display 12) is displayed on the game auxiliary display 12, suggesting that the stopping pattern advantageous to the player is a stopping operation sequence of right, left, and center, and during a game in which "4" is set as the navigation number, navigation display 4 (a display that displays "32" on the game auxiliary display 12) is displayed on the game auxiliary display 12, suggesting that the stopping pattern advantageous to the player is a stopping operation sequence of right, center, and left.

[0084] In response to this, the sub-control unit 91, during a game in which the navigation number "1" is specified based on a command received from the main control unit 41, causes the LCD display 51 to display navigation image 1 suggesting that the stopping pattern advantageous to the player is a stopping operation sequence of center, left, and right; during a game in which the navigation number "2" is specified, causes the LCD display 51 to display navigation image 2 suggesting that the stopping pattern advantageous to the player is a stopping operation sequence of center, right, and left; during a game in which the navigation number "3" is specified, causes the LCD display 51 to display navigation image 3 suggesting that the stopping pattern advantageous to the player is a stopping operation sequence of right, left, and center; and during a game in which the navigation number "4" is specified, causes the LCD display 51 to display navigation image 4 suggesting that the stopping pattern advantageous to the player is a stopping operation sequence of right, center, and left.

[0085] In this embodiment, the navigation notification is configured to notify the player of the stop operation sequence (correct pressing sequence) as the operation mode of the stop switches 8L, 8C, and 8R that is advantageous to the player, but the navigation notification may be configured to suggest the operation timing of the stop switches 8L, 8C, and 8R that is advantageous to the player, or to suggest a combination of the stop operation sequence and operation timing of the stop switches 8L, 8C, and 8R that is advantageous to the player. For example, if the operation mode of the stop switches that is advantageous to the player is a predetermined operation timing for a predetermined reel, the game auxiliary display 12 can display the number of the pattern corresponding to the predetermined operation timing together with the number corresponding to the predetermined reel, or the liquid crystal display 51 can display an image of the pattern corresponding to the predetermined operation timing at a position corresponding to the predetermined reel, thereby suggesting the operation mode.

[0086] [About the game area] As shown in FIG. 6, the main control unit 41 can control the game zone to be either a normal zone or an advantageous zone.

[0087] The normal section is a game section where no navigation notification is performed, and is started when the next game is started after the data related to the game (data indicating the game state, data indicating the game section, BB winning flag, etc.) is initialized by changing the settings, or after the advantageous section ends. After that, the normal section ends in a game where the advantageous section transition role is won by an internal lottery in a game controlled to a game state other than the special state.

[0088] The advantageous zone is a game zone where a navigation notification may be performed, and is a game zone that is more advantageous to the player than the normal zone because the navigation notification may be performed. The advantageous zone is started when a game controlled to a game state other than a special state in a game in a normal zone is selected by an internal lottery to select an advantageous zone transition role, and the game is started when the next game is started. The advantageous zone is then ended when the end conditions of the advantageous zone (end conditions 1 and 2 described below) are met.

[0089] In the advantageous zone, when a specific notification condition is met (in this embodiment, the reel is controlled to the AT state described below, and the navigation target role is selected in an internal lottery), a navigation notification can be made, and the player is notified of the operation mode of the stop switches 8L, 8C, and 8R that is advantageous to the player.

[0090] The main control unit 41 controls the advantageous zone, and when it is controlled to an AT state in which a navigation notification is performed, when a navigation target role is won in an internal lottery, it can control the navigation notification (control to display a navigation display on the game assistance display 12, control to send a command that can identify the navigation number corresponding to the navigation display, etc.) to notify the player of the operation mode of the stop switches 8L, 8C, 8R that is advantageous to the player, and the advantageous zone is a game zone that is more advantageous to the player than the normal zone.

[0091] The conditions for ending the favorable zone include End Condition 1, which is established when the net increase in the number of medals (number of medals given - number of medals used) in the favorable zone exceeds a specified number (2400 in this embodiment) set as the upper limit number, and End Condition 2, which is established when a predetermined arbitrary condition (in this embodiment, the remaining net increase in the number of medals (upper limit number - net increase in the favorable zone) at the end of the AT2 state described later is a specific value (200 in this embodiment) or less) is satisfied, and the favorable zone ends when at least one of End Conditions 1 and 2 is established. The net increase in the number of medals in the favorable zone is counted as a negative value, and if the medals decrease, it can take a negative value. In this case, the medals then increase and recover to 0, become a positive value, and exceed the specified number, and End Condition 1 is established. For this reason, a situation may occur in which the medals increase by more than 2400 medals from when the net increase in the number of medals in the favorable zone is a negative value and the medals increase by more than 2400 medals before End Condition 1 is established.

[0092] In this embodiment, when the gaming area is controlled to the normal area, the gaming area is transitioned to an advantageous area by winning a predetermined advantageous area transition role. However, it may also be configured that when the gaming area is controlled to the normal area, a advantageous area transition lottery is held by winning a role eligible for advantageous area transition in an internal lottery, and the gaming area is transitioned to an advantageous area by winning the advantageous area transition lottery.

[0093] In addition, in this embodiment, the advantageous zone ends when the net increase in the number of medals in the advantageous zone (number of medals awarded - number of medals used) exceeds a specified number set as the upper limit (2400 in this embodiment), but the advantageous zone may also end when an ending condition is met in which the number of games in the advantageous zone (number of games in the advantageous zone) reaches a specified number set as the upper limit game number (for example, 1500 games), or when any of these multiple conditions is met.

[0094] [Regarding the transition of game zone and advantageous zone states] Next, the transition of the advantageous zone state in the game zone and the advantageous zone by the main control unit 41 will be described with reference to Figs.

[0095] When a favorable zone transition role is selected by an internal lottery in a game played in the normal zone, the main control unit 41 transitions the game zone to the favorable zone from the next game. The favorable zone is composed of multiple types of game zone states, including a normal state, a premonition state, a CZ1 state, a CZ2 state, an AT1 state, an AT2 state, and a preparation state.

[0096] As shown in FIG. 7, the normal state is a state in which no navigation notification is performed, and is a relatively disadvantageous state for the player. The premonition state is a state in which the player transitions after the end of the normal state and in which no navigation notification is performed, but which always transitions to the CZ1 state after that, and in this respect is a more advantageous state for the player than the normal state. The CZ1 state is a state in which no navigation notification is performed, but which may transition to the AT1 state after that, and is a more advantageous state for the player than the normal state and the premonition state. The CZ2 state is a state in which no navigation notification is performed, but which may transition to the AT2 state after that, and is a more advantageous state for the player than the normal state and the premonition state. In addition, the CZ2 state is a state in which the probability of winning the AT lottery is higher than the CZ1 state, and furthermore, as described later, when the AT lottery is won, the player transitions to the AT2 state, which is more advantageous than the AT1 state, and is a more advantageous state for the player than the CZ1 state. In this embodiment, the CZ2 state is more advantageous than the CZ1 state in that the probability of winning the AT lottery is higher than the CZ1 state and the state transitions to the AT2 state, which is more advantageous than the AT1 state, when the AT lottery is won. However, it is sufficient that the CZ2 state is more advantageous than the CZ1 state in that the probability of winning the AT lottery is higher than the CZ1 state, the state transitions to the AT2 state, which is more advantageous than the AT1 state, when the AT lottery is won, and the rate of winning the AT2 state out of the AT1 state and the AT2 state is higher than the CZ1 state when the AT lottery is won. The AT1 state is an AT state in which a navigation notification is performed, and is more advantageous to the player than the normal state, the precursor state, the CZ1 state, and the CZ2 state. The AT2 state is an AT state in which a navigation notification is performed, and is more advantageous to the player than the normal state, the precursor state, the CZ1 state, and the CZ2 state. In addition, the AT2 state is more advantageous to the player than the AT1 state in that more medals can be expected to be awarded than in the AT1 state, the number of games can be increased, and the state always transitions to the CZ2 state after the end of the AT2 state. The preparation state is a state in which no navigation notification is performed, and is a state that is controlled before the start of the CZ2 state if the advantageous zone continues after the end of the AT2 state.

[0097] Among these advantageous zone states, in the normal state, the premonition state, the CZ1 state, and the CZ2 state in which the navigation notification is not performed, a penalty is given if a game is played in a stop operation sequence in which a reel other than the left reel is the first stop. Specifically, in the normal state and the premonition state, the number of games ended, which will be described later, is not updated, and in the CZ1 state and the CZ2 state, the AT lottery is not performed. In addition, the sub-control unit 91 executes a warning notification to the effect that a penalty has been given if a game is played in a stop operation sequence in which a reel other than the left reel is the first stop in the normal state, the premonition state, the CZ1 state, and the CZ2 state, and to encourage a game to be played in a stop operation sequence in which the left reel is the first stop.

[0098] On the other hand, in the AT1 and AT2 states where the navigation notification is performed, even if a game is played in a stop operation sequence in which a reel other than the left reel is the first stop, no penalty is given and no warning notification is given. Also, in the preparation state, although the navigation notification is not performed, even if a game is played in a stop operation sequence in which a reel other than the left reel is the first stop, no penalty is given and no warning notification is given.

[0099] The main control unit 41 shifts the game zone to the advantageous zone when the advantageous zone shift role is won in the normal zone. At this time, it is determined whether the game state is not in the internal zone or in the internal zone, and if it is determined that it is not in the internal zone, a mode lottery and a game number lottery are performed, and control is performed to the normal zone. Since the game zone is always shifted to the advantageous zone when the BB, which shifts to the internal zone, is won in the non-internal zone, the control to the normal zone in the non-internal zone is the situation after the data related to the game (data indicating the game state, data indicating the game zone, BB winning flag, etc.) is initialized by the setting change. Therefore, when the game zone is shifted to for the first time after the setting change, the game zone is first controlled to the normal zone.

[0100] The mode selection determines the normal mode to be controlled thereafter. The game number selection determines one of a plurality of game number ranges according to the mode selected in the mode selection, and further determines the number of games to be played from the determined range.

[0101] The main control unit 41 adds the number of games played since the control to the normal state (called the normal game number) for each game in the normal state. The normal game number may be configured to add a specified value (for example, 1) for each game, or may be configured to determine the number of added games according to the result of an internal lottery and add the determined number of added games. Also, the number of added games may be increased during a specific period.

[0102] The main control unit 41 judges whether the normal game number after the addition reaches the end game number determined by the game number lottery, and if the end game number is reached, ends the normal state and controls the state to the premonition state for a predetermined period (16 to 32 games in this embodiment). Then, when the premonition state ends, the state is controlled to the CZ1 state.

[0103] In this embodiment, the configuration is such that the premonition state and the subsequent CZ1 state are controlled based on the normal state ending when the number of normal games reaches the end game number selected according to the mode of the normal state, but the configuration may also be such that the premonition state and the subsequent CZ1 state are controlled based on the normal state ending when the normal state ending is achieved by winning the end lottery held for each game or when a specific role is won or awarded, rather than just when the number of normal games reaches the end game number, or the configuration may be such that the premonition state and the subsequent CZ1 state are controlled only based on the normal state ending when the normal state ending is achieved by winning the end lottery held for each game or when a specific role is won or awarded.

[0104] The CZ1 state is controlled for a period of 20 games, during which the main control unit 41 performs an AT lottery to determine whether or not to control to the AT state each time an AT lottery target role is won. The winning probability of the AT lottery is set for each lottery trigger and FC assigned to the AT lottery target role, as shown in Figure 8, and whether or not to control to the AT state is determined by the winning probability corresponding to the lottery trigger and the FC of the AT lottery target role that is won.

[0105] The main control unit 41 ends the CZ1 state after 20 games have elapsed since the start of the CZ1 state. If the AT lottery is won before the CZ1 state ends, control is exercised to switch to the AT1 state from the next game. On the other hand, if the AT lottery is not won before the CZ1 state ends, the above-mentioned mode lottery and game number lottery are performed to determine the mode and end game number of the subsequent normal state, and control is exercised to switch to the normal state from the next game.

[0106] The AT1 state consists of 15 point-up games and up to 3 condition-determining games. If the target role for the navigation notification is won in either game, the navigation notification will be performed, so you can expect an increase in medals.

[0107] When the AT1 state starts, the main control unit 41 first controls the game to be a point-up game, and then controls the game to be a condition determination game of up to three games after 15 games have elapsed.

[0108] In this embodiment, the number of games in the point-up game is 15, but the number of games in the point-up game may be varied by drawing an end lottery upon a predetermined trigger in the point-up game (such as winning a specific role) or for each game, and by winning the end lottery, the point-up game ends and becomes a condition determination game, or by determining the number of games in the point-up game by drawing a lottery to be one of multiple game numbers.

[0109] The main control unit 41 performs a condition determination lottery for each game in the condition determination game, and if the condition determination lottery is won for three consecutive games, the main control unit 41 ends the AT1 state as the condition is met and controls the next game to the AT2 state. On the other hand, if the condition determination lottery is not won even once, the main control unit 41 ends the AT1 state as the condition is not met in that game, and then performs the above-mentioned mode lottery and game number lottery to determine the mode of the normal state and the number of games to end, and controls the next game to the normal state.

[0110] In the condition determination lottery, the winning probability is calculated by adding the winning probability according to the number of points accumulated since the start of the favorable zone to the initial winning probability. The number of points is awarded by winning the point lottery held in the normal state, premonition state, and AT1 state, and is accumulated until the transition to the AT2 state.

[0111] In this embodiment, the configuration is such that the state is controlled to AT2 by achieving a condition in a condition determination game in the AT1 state, but the configuration may also be such that an AT lottery is conducted in the AT1 state and the state is controlled to AT2 by winning the AT lottery.

[0112] When the AT2 state starts, the main control unit 41 sets the initial value of the remaining number of games to 30. Then, the main control unit 41 subtracts the remaining number of games for each game, and ends the AT2 state when the remaining number of games becomes 0.

[0113] In addition, the main control unit 41 performs an add-on lottery to determine whether or not to add the remaining number of games and the number of games when an add-on target role (a lottery role corresponding to FC4 to 6) is won in the AT2 state, and if the add-on lottery is won, the won number of games is added to the remaining number of games. Even if an add-on target role is won in the AT2 state, if the remaining net increase in number of coins (upper limit number of coins - net increase in number of coins during the advantageous zone) is less than a specific number (200 in this embodiment), an add-on lottery is not performed, and the addition of the remaining number of games is limited. The specific number is a numerical value larger than the number of medals expected to increase by the addition of the number of games when an add-on target role (a lottery role corresponding to FC6) that can be expected to add the largest number of games is won. For this reason, it becomes difficult to add the number of games in which the net increase in number of coins during the advantageous zone exceeds the upper limit number.

[0114] In this embodiment, when the target role for addition is won in the AT2 state, if the remaining net increase number (upper limit number-net increase number in the favorable zone) is a specific number (200 in this embodiment) or less, the lottery for addition is not performed. However, for example, the target role for addition is increased, or the probability of winning the lottery for addition is increased. In such a configuration, when the remaining net increase number is a specific number or less in the AT2 state, the control of the addition state may be restricted, while the lottery for addition is performed when the target role for addition is won. Also, in a configuration that can be controlled to multiple types of addition states with different numbers of games expected to be added, when the remaining net increase number is a specific number or less in the AT2 state, only some types of addition states in which the number of games expected to be added is relatively large may be restricted.

[0115] In addition, the main control unit 41 performs a stock lottery to determine whether or not to grant the right to control again to the AT2 state when a stock lottery target role (a lottery role corresponding to FC5 to 7) is won in the AT2 state, and if the stock lottery is won, the right to win the AT is stocked. When the right to win the AT is stocked, the sub-control unit 91 notifies the fact and notifies the number of remaining AT winning rights in an identifiable manner. In addition, even if a stock lottery target role is won in the AT2 state, if the remaining net increase in the number of coins (upper limit number of coins - net increase in the number of coins in the advantageous zone) is less than a specific number (200 in this embodiment), the stock lottery is not performed, and the control of the AT2 state again is restricted.

[0116] When the number of remaining games becomes 0 in the AT2 state, the main control unit 41 ends the AT2 state. At this time, if the right to win the AT is stocked, the stocked right to win the AT is subtracted by 1, and the control returns to the AT2 state from the next game. Also, if the right to win the AT is not stocked, it determines whether the remaining net increase in number (upper limit number-net increase in number in the advantageous zone) is a specific number (200 in this embodiment) or less, and if the remaining net increase in number is the specific number or less, the advantageous zone is ended and the game zone is shifted to the normal zone. At this time, all data related to the AT (net increase in number in the advantageous zone, number of points accumulated since the start of the advantageous zone, etc.) are initialized. Also, if the right to win the AT is not stocked and the remaining net increase in number is not the specific number or less (exceeds the specific number), the control returns to the preparation state from the next game while continuing the advantageous zone.

[0117] In this way, it is determined whether the remaining net increase in the number of coins (maximum number of coins - net increase in the advantageous zone) at the end of the AT2 state is less than a specific number (200 in this embodiment), and if the remaining net increase in the number of coins is less than the specific number, the advantageous zone is ended and the game zone is transitioned to the normal zone.This prevents the net increase in the number of coins in the advantageous zone exceeding the maximum number of coins during the AT2 state, thereby meeting the conditions for ending the advantageous zone and suddenly ending the AT2 state, or restricting the addition of the remaining number of games through an additional lottery or the granting of rights to the AT2 state through a stock lottery so as not to reach the maximum number of coins.

[0118] Also, when the remaining net increase in number of coins (maximum number of coins - net increase in number of coins during the favorable zone) is below a specific number (200 in this embodiment), an additional lottery may be won, and a large number of games may be added at once, resulting in an increase in medals of a specific number or more. Even in a situation where an increase in medals of a specific number or more is not expected due to the addition of the number of games, the game may be controlled to the AT2 state again when the remaining net increase in number of coins is below a specific number due to the right to win the AT previously stocked. In such a case, even before the number of remaining games becomes 0 in the AT2 state, the net increase in number of coins in the favorable zone may exceed the maximum number of coins, and the end condition 1 of the favorable zone may be established.

[0119] For this reason, when the result of the remaining game number being added in the additional lottery is that the sum of the net increase in the current favorable zone and the net increase in the number of coins expected to increase based on the current remaining game number and the stocked AT rights exceeds the upper limit, the main control unit 41 controls the state to the ED state, and continues the AT2 state until the net increase in the favorable zone exceeds the upper limit and the end condition 1 of the favorable zone is satisfied, regardless of the remaining game number, and ends the AT2 state together with the favorable zone when the end condition 1 is satisfied. In such a case, the main control unit 41 ends the AT2 state, ends the favorable zone, and transitions the game zone to the normal zone. In addition, it initializes all data related to the AT (the net increase in the favorable zone, the number of points accumulated since the start of the favorable zone, etc.). In addition, when the sub-control unit 91 controls the state to the ED state, it executes an ED performance (FIG. 20(a)) that is different in form from the AT2 performance (FIG. 18(a)) described later. In the ED performance, the number of remaining games and the number of AT winning rights stored, which are displayed in the AT2 performance, are not displayed, and the remaining increase in the number of medals until the end condition 1 is met is announced.

[0120] When the advantageous zone transition role is won in the preparation state, the main control unit 41 performs an AT lottery, ends the preparation state, and controls the next game to the CZ2 state. The preparation state ends when the advantageous zone transition role is won, so it is controlled for a period of at least one game.

[0121] The CZ2 state is controlled for a period of five games, and the main control unit 41 performs an AT lottery in the first game of the CZ2 state. When the main control unit 41 ends the CZ2 state after five games have elapsed, if the player wins either the AT lottery performed at the start of the preparation state or the AT lottery performed in the first game of the CZ2 state, the main control unit 41 ends the CZ2 state and controls the game to the AT2 state from the next game. On the other hand, if the player does not win either the AT lottery performed at the start of the preparation state or the AT lottery performed in the first game of the CZ2 state, the main control unit 41 ends the CZ2 state and performs the above-mentioned mode lottery and game number lottery to determine the mode and end game number of the normal state thereafter, and controls the game to the normal state from the next game.

[0122] In addition, if the main control unit 41 determines that the game state is internal when a beneficial zone transition role is won in the normal zone and the game transitions to the beneficial zone, it conducts an AT lottery, controls the game to the CZ2 state from the next game, and conducts an AT lottery in the first game in the CZ2 state.

[0123] As mentioned above, when the BB is won during a non-internal period, the game will always transition to the advantageous zone when the BB is won, which will transition to the internal period. Therefore, when the game is controlled to the normal zone during an internal period, the game will always be controlled after the advantageous zone ends, not after the data related to the game (data indicating the game state, data indicating the game zone, BB winning flag, etc.) is initialized by changing the settings. In addition, since the condition for the end of the advantageous zone is rarely met in an advantageous zone state other than the AT2 state, it is essentially a state in which the AT2 state ends and the game transitions to the normal zone. For this reason, when the game transitions to the advantageous zone again from the normal zone after the advantageous zone ends due to the end of the AT2 state, the game will first be controlled to the CZ2 state, and then, when the CZ2 state ends, if the AT lottery performed at the time of transition to the advantageous zone or the AT lottery performed in the first game of the CZ2 state has been won, the game will be controlled to the AT2 state. If the AT lottery performed at the time of transition to the advantageous zone or the AT lottery performed in the first game of the CZ2 state has not been won, the game will be controlled to the normal state.

[0124] [About the AT lottery] In this embodiment, as shown in FIG. 8, the AT lottery is triggered by the winning of a role subject to AT lottery in the CZ1 state, which is controlled through the normal state and the premonition state (CZ1 state), when a role that is subject to AT lottery is won, which triggers a transition from the normal zone to the favorable zone after the favorable zone ends with the end of the AT2 state (at the time of favorable zone transition (inside)), when a role that is subject to favorable zone transition is won, which triggers a transition from the preparation state to the CZ2 state while the favorable zone continues after the end of the AT2 state (at the end of preparation state (at the time of winning the favorable zone transition role)), and the first game in the CZ2 state (CZ2 state).

[0125] As shown in FIG. 8, in the AT lottery in the CZ1 state, the target AT state is the AT1 state, and when the target role for the AT lottery belongs to FC1 (when a 1-piece small role is won), the winning probability is 2.5%, when the target role for the AT lottery belongs to FC2 (when a normal replay is won), the winning probability is 5%, when the target role for the AT lottery belongs to FC3 (when a rare small role D is won), the winning probability is 6.25%, when the target role for the AT lottery belongs to FC4 (when a rare small role C is won), the winning probability is 12.5%, when the target role for the AT lottery belongs to FC5 (when a rare small role B is won), the winning probability is 25%, when the target role for the AT lottery belongs to FC6 (when a rare replay is won), the winning probability is 50%, and when the target role for the AT lottery belongs to FC7 (when a rare small role A is won), the winning probability is set to 100%.

[0126] Also, as shown in Figure 8, in the AT lottery during the transition to the favorable zone (inside), the target AT state is the AT2 state, and when the favorable zone transition role belongs to FC0 or FC1 (when the push order role or 1-coin small role is won), the winning probability is set to 60%, and when the favorable zone transition role belongs to FC3 to FC7 (when the rare replay, rare small role A, rare small role B, rare small role C, or rare small role D is won), the winning probability is set to 100%.

[0127] Also, as shown in Figure 8, in the AT lottery at the end of the preparation state (winning the advantageous zone transition role), the target AT state is the AT2 state, and when the advantageous zone transition role belongs to FC0 or FC1 (when the push order role or 1-coin small role is won), the winning probability is set to 60%, and when the advantageous zone transition role belongs to FC3 to FC7 (when the rare replay, rare small role A, rare small role B, rare small role C, or rare small role D is won), the winning probability is set to 100%.

[0128] Also, as shown in FIG. 8, in the AT lottery in the first game in the CZ2 state after the AT2 state ends, the target AT state is the AT2 state. In this case, the winning probability differs depending on whether the number of times controlled to the AT2 state after the AT1 state is 1 to 3 times, 4 times or more, or whether the state was controlled to the AT2 state without going through AT1 as a result of going through the normal section. If the number of times controlled to the AT2 state after the AT1 state is 1 to 3 times, the winning probability is set to 50% when the result of the internal lottery in the game belongs to FC0 to FC2 (when the push order role, 1-piece small role, and normal replay are won), 80% when the result of the internal lottery in the game belongs to FC3 to FC4 (when rare small role C and rare small role D are won), and 100% when the result of the internal lottery in the game belongs to FC5 to FC7 (when rare replay, rare small role A, and rare small role B are won). If the number is 4 or more, if the result of the internal lottery in the game belongs to FC0 to FC2 (when the push order role, 1-coin role, or normal replay is won), the winning probability is set to 70%, and if the result of the internal lottery in the game belongs to FC3 to FC7 (when rare replay, rare minor role A, rare minor role B, rare minor role C, or rare minor role D is won), the winning probability is set to 100%.If the result of going through the normal section is controlled to the AT2 state without going through AT1, the winning probability is set to 70% if the result of the internal lottery in the game belongs to FC0 to FC2 (when the push order role, 1-coin role, or normal replay is won), and the winning probability is set to 100% if the result of the internal lottery in the game belongs to FC3 to FC7 (when rare replay, rare minor role A, rare minor role B, rare minor role C, or rare minor role D is won).

[0129] In this embodiment, the AT lottery is held in both the CZ2 state, which is controlled at the start of the advantageous zone transitioned from the normal zone after the advantageous zone ends with the end of the AT2 state, and the CZ1 state, which is controlled after the CZ2 state ends via the normal state and the premonition state. However, if the AT lottery is won in the CZ1 state, the player will be controlled to the AT1 state, whereas if the AT lottery is won in the CZ2 state, the player will be controlled to the AT2 state, which is relatively more advantageous than the AT1 state. After the advantageous zone starts and the CZ2 state ends, the player will be controlled to the AT2 state after the AT1 state, in which more medals can be expected to be won than in the AT1 state. However, if the advantageous zone has ended at the end of the AT2 state, the player can expect to be controlled to the AT2 state, which is relatively more advantageous than the AT1 state, without going through the AT1 state, when the advantageous zone starts thereafter.

[0130] In addition, the probability of winning the AT lottery is set higher in the CZ2 state than in the CZ1 state, and if the favorable zone ends when the AT2 state ends, it can be expected that when the favorable zone starts afterwards, the player will be controlled to the AT2 state, which is relatively more favorable than the AT1 state, without going through the AT1 state.

[0131] In this embodiment, the system is configured to be controlled to the CZ2 state at the start of the favorable zone transitioned from the normal zone after the favorable zone ends with the end of the AT2 state, and is not controlled to the CZ2 state at the start of the favorable zone transitioned to for the first time after the setting is changed. However, the system may also be configured to be controlled to the CZ2 state even at the start of the favorable zone transitioned to for the first time after the setting is changed.

[0132] In addition, in this embodiment, the AT lottery is conducted every time an AT lottery-eligible role is won in the CZ1 state, but the AT lottery may be conducted for every game in the CZ1 state, or the AT lottery may be conducted only for a specific game (for example, the first game) in the CZ1 state.

[0133] In addition, in this embodiment, the AT lottery is conducted only in the first game in the CZ2 state, but it may be configured to conduct the AT lottery in a specific game other than the first game in the CZ2 state, or to conduct the AT lottery for every game in the CZ2 state, or to conduct the AT lottery every time a role eligible for the AT lottery is won in the CZ2 state.

[0134] Furthermore, in this embodiment, the AT lottery in the CZ1 state is configured to select the AT1 state, and the AT lottery in the CZ2 state at the start of the favorable zone is configured to select the AT2 state, however, it is also possible to configure the AT lottery in the CZ1 state to select both the AT1 state and the AT2 state, the AT lottery in the CZ2 state at the start of the favorable zone to select both the AT1 state and the AT2 state, or the AT lottery in the CZ1 state and the AT lottery in the CZ2 state at the start of the favorable zone to select both the AT1 state and the AT2 state. Even with such a configuration, for example, as shown in Figure 21, by setting the winning probability so that in the AT lottery for the CZ1 state, the rate of winning the AT1 state out of the AT1 state and the AT2 state is higher, and in the AT lottery for the CZ2 state at the start of the favorable zone, the rate of winning the AT2 state out of the AT1 state and the AT2 state is higher, if the favorable zone ends at the end of the AT2 state, it can be expected that when the favorable zone starts thereafter, the player will be controlled to the AT2 state, which is relatively more favorable than the AT1 state, without passing through the AT1 state.

[0135] In addition, in this embodiment, after the transition to the favorable zone and the end of the CZ2 state, the AT lottery is not performed in the normal state and premonition state until it is controlled to the CZ1 state, but it may be configured to perform the AT lottery in the normal state and premonition state until it is controlled to the CZ1 state. Even in such a configuration, in the AT lottery in the normal state and premonition state, the AT lottery is configured to be configured so that only the AT1 state is won or the winning probability is set so that the ratio of winning the AT1 state among the AT1 state and the AT2 state is high, and in the AT lottery in the CZ2 state at the start of the favorable zone, the AT lottery is configured so that only the AT2 state is won or the winning probability is set so that the ratio of winning the AT2 state among the AT1 state and the AT2 state is high. In this way, if the favorable zone has ended at the end of the AT2 state, it can be expected that when the favorable zone starts thereafter, it will be controlled to the AT2 state, which is relatively more favorable than the AT1 state, without passing through the AT1 state.

[0136] In this embodiment, when the advantageous zone transition role that triggers the transition from the normal zone to the advantageous zone after the advantageous zone ends with the end of the AT2 state is won, the AT lottery is held in both the CZ1 state, which is controlled after the CZ2 state ends via the normal state and the premonition state, but if the AT lottery is won in the CZ1 state, the player is controlled to the AT1 state, whereas if the AT lottery is won at the time of the transition to the advantageous zone, the player is controlled to the AT2 state, which is relatively more advantageous than the AT1 state. After the advantageous zone begins and the CZ2 state ends, the player can be controlled to the AT2 state after the AT1 state, in which more medals can be expected to be won than in the AT1 state. However, if the advantageous zone has ended at the end of the AT2 state, it can be expected that when the advantageous zone starts thereafter, the player will be controlled to the AT2 state, which is relatively more advantageous than the AT1 state, without passing through the AT1 state.

[0137] In addition, the probability of winning the AT lottery is set higher when transitioning to a favorable zone than when in the CZ1 state, and if the favorable zone ends when the AT2 state ends, it can be expected that when the favorable zone begins thereafter, the player will be controlled to the AT2 state, which is relatively more favorable than the AT1 state, without passing through the AT1 state.

[0138] In addition, in this embodiment, an AT lottery is conducted when a favorable zone transition role is won, which triggers a transition from the normal zone to the favorable zone after the favorable zone ends with the end of the AT2 state, and an AT lottery is not conducted when a favorable zone transition role is won, which triggers a transition to the favorable zone for the first time after the setting is changed.However, it is also possible to configure the AT lottery to be conducted when a favorable zone transition role is won, which triggers a transition to the favorable zone for the first time after the setting is changed.

[0139] In addition, in this embodiment, the AT lottery in the CZ1 state is the AT1 state, and the AT lottery at the time of the transition to the favorable zone is the AT2 state, but it may be configured so that both the AT1 state and the AT2 state are the lottery targets in the AT lottery in the CZ1 state, or both the AT1 state and the AT2 state are the lottery targets in the AT lottery at the time of the transition to the favorable zone, or both the AT1 state and the AT2 state are the lottery targets in the AT lottery in the CZ1 state and the AT lottery at the time of the transition to the favorable zone. Even in such a configuration, for example, as shown in FIG. 21, by setting the winning probability so that the AT lottery in the CZ1 state has a high probability of winning the AT1 state out of the AT1 state and the AT2 state, and the AT lottery at the time of the transition to the favorable zone has a high probability of winning the AT2 state out of the AT1 state and the AT2 state, if the favorable zone ends at the end of the AT2 state, it can be expected that when the favorable zone starts after that, it will be controlled to the AT2 state, which is relatively more favorable than the AT1 state, without going through the AT1 state.

[0140] Furthermore, even if the AT lottery is performed in the normal state and premonition state until it is controlled to the CZ1 state as described above, the AT lottery in the normal state and premonition state can be configured so that only the AT1 state is won, or the winning probability is set so that the proportion of winning the AT1 state among the AT1 state and the AT2 state is higher, and the AT lottery during the transition to the favorable zone can be configured so that only the AT2 state is won, or the winning probability is set so that the proportion of winning the AT2 state among the AT1 state and the AT2 state is higher.By doing this, if the favorable zone has ended at the end of the AT2 state, it can be expected that when the favorable zone begins afterwards, it will be controlled to the AT2 state, which is relatively more favorable than the AT1 state, without passing through the AT1 state.

[0141] In this embodiment, the AT lottery is performed at the time of the transition to the advantageous zone (inside), and the probability of winning the advantageous zone transition role and winning the AT lottery is less than 50%. In other words, at the time of the transition to the advantageous zone, the probability of not being determined to be controlled in the AT state is higher than the probability of being determined to be controlled in the AT state, and the ratio of being determined to be controlled in the AT state at the same time as the transition to the advantageous zone is suppressed, so that excessive gambling is not encouraged. In addition, in the advantageous zone, there is a role that is the target of the AT lottery but is not a role that transitions to the advantageous zone (normal replay), and when the role is won in the normal zone, there is no transition to the advantageous zone and no AT lottery is performed, so that the normal zone is not as advantageous as the advantageous zone. In addition, for roles that win the AT lottery 100% when won, such as FC3 to FC7, a configuration may be made in which a role that is the target of the AT lottery in the advantageous zone and is not a role that transitions to the advantageous zone is provided, and by making such a configuration, the difference in the degree of advantage between the normal zone and the advantageous zone becomes even clearer.

[0142] In this embodiment, the AT lottery is held in both the CZ2 state, in which control continues after the AT2 state ends while the favorable zone continues, and the CZ1 state, in which control passes through the normal state and premonition state after the CZ2 state ends; however, if the AT lottery is won in the CZ1 state, the player is controlled to the AT1 state, whereas if the AT lottery is won in the CZ2 state, the player is controlled to the AT2 state, which is relatively more favorable than the AT1 state; and after the AT2 state ends, regardless of whether the favorable zone has ended or not, the player can expect to be controlled to the AT2 state, which is relatively more favorable than the AT1 state, without passing through the AT1 state.

[0143] In addition, the probability of winning the AT lottery is set higher in the CZ2 state than in the CZ1 state, and after the end of the AT2 state, regardless of whether the advantageous zone has ended or not, it can be expected that the player will be controlled to the AT2 state, which is relatively more advantageous than the AT1 state, without passing through the AT1 state.

[0144] In this embodiment, the AT1 state is the subject of the AT lottery in the CZ1 state, and the AT2 state is the subject of the AT lottery in the CZ2 state after the AT2 state ends; however, it is also possible to configure the AT lottery in the CZ1 state to include both the AT1 state and the AT2 state, or to configure the AT lottery in the CZ2 state after the AT2 state ends to include both the AT1 state and the AT2 state to be the subject of the AT lottery, or to configure the AT lottery in the CZ1 state and the AT lottery in the CZ2 state after the AT2 state ends to include both the AT1 state and the AT2 state to be the subject of the AT lottery. Even with such a configuration, for example, as shown in Figure 21, by setting the winning probability so that in the AT lottery for the CZ1 state, the rate of winning the AT1 state is higher between the AT1 state and the AT2 state, and in the AT lottery for the CZ2 state after the end of the AT2 state, the rate of winning the AT2 state is higher between the AT1 state and the AT2 state, it can be expected that after the end of the AT2 state, regardless of whether the advantageous zone has ended or not, the player will be controlled to the AT2 state, which is relatively more advantageous than the AT1 state, without passing through the AT1 state.

[0145] Furthermore, even if the AT lottery is performed in the normal state and premonition state until it is controlled to the CZ1 state as described above, the AT lottery in the normal state and premonition state can be configured so that only the AT1 state is won, or the winning probability is set so that the proportion of winning the AT1 state among the AT1 state and the AT2 state is higher, and the AT lottery in the CZ2 state after the AT2 state ends can be configured so that only the AT2 state is won, or the winning probability is set so that the proportion of winning the AT2 state among the AT1 state and the AT2 state is higher.By doing this, after the AT2 state ends, regardless of whether the advantageous zone has ended or not, it can be expected that the game will be controlled to the AT2 state, which is relatively more advantageous than the AT1 state, without passing through the AT1 state.

[0146] In this embodiment, once the game is controlled to the normal state in the advantageous zone, in the CZ1 state where the AT lottery is then held, if the AT lottery is won at the end of that state, the game will first be controlled to the relatively disadvantageous AT1 state, and only when the conditions are met in the condition determination game in the AT1 state will the game be controlled to the AT2 state, which is more advantageous than the AT1 state.

[0147] On the other hand, once the AT2 state is controlled, after the AT2 state ends, the device will be put into the CZ2 state, which is likely to be controlled back to the AT2 state. Therefore, once the device is controlled into the AT2 state, it can be expected that the AT2 state will continue.

[0148] In addition, in the CZ2 state which is controlled after the AT2 state ends, the probability of winning the AT lottery is set to be higher if the number of times the AT2 state has been controlled to after the AT1 state is four or more than if the number of times the AT2 state has been controlled to after the AT1 state is one to three. Therefore, if the number of times the AT2 state has been controlled to after the AT1 state is four or more, it can be expected that the AT2 state will continue.

[0149] In addition, in the AT2 state, if the net increase in the number of coins in the favorable zone exceeds the upper limit and the favorable zone ends with the AT2 state, if the remaining net increase in the number of coins at the end of the AT2 state falls below a specific number and the favorable zone ends, the data related to the AT will be initialized. However, at the start of the favorable zone, the player will then be placed in the CZ2 state, which is likely to be controlled to the AT2 state. Therefore, by being controlled to the AT2 state once, it can be expected that the AT2 state will continue even if the favorable zone ends midway.

[0150] In addition, the favorable zone is likely to end at the end of the AT2 state if the number of times it has been controlled to the AT2 state after the AT1 state is four or more, and even in the CZ2 state which is controlled at the start of the favorable zone, just as in the case where the number of times it has been controlled to the AT2 state after the AT1 state is four or more, the probability of winning the AT lottery at the end of the CZ2 state is set higher than when the number of times it has been controlled to the AT2 state after the AT1 state is one to three. Therefore, if the number of times it has been controlled to the AT2 state after the AT1 state is four or more, it can be expected that the AT2 state will continue even if the favorable zone ends midway.

[0151] Also, even if the player is controlled to the CZ2 state without going through the AT1 state at the start of the favorable zone, and then is controlled to the AT2 state and then enters the CZ2 state, regardless of the number of times it has been controlled to the AT2 state, the probability of winning the AT lottery at the end of the CZ2 state is set to be higher than if the player has been controlled to the AT2 state 1 to 3 times after the AT1 state, just as in the case where the player has been controlled to the AT2 state 4 or more times after the AT1 state.Therefore, if the player has been controlled to the AT2 state 4 or more times after the AT1 state, it can be expected that the AT2 state will continue even if the favorable zone ends midway.

[0152] Furthermore, in this embodiment, when transitioning to a favorable zone, if the favorable zone is one transitioned from a normal zone after the favorable zone ends with the end of the AT state, the main control unit 41 controls the zone to the CZ2 state, whereas when transitioning from a normal zone to a favorable zone for the first time after a setting change, the main control unit 41 does not control the zone to the CZ2 state at the start of the favorable zone, but controls the zone to the normal state, so that even if the gaming establishment changes the setting, the zone will not be intentionally controlled to the CZ2 state, which is favorable to the player.

[0153] In addition, the main control unit 41 determines whether the game state is inside or not inside at the time of transition to the advantageous zone, and thereby identifies whether the advantageous zone is one transitioned from the normal zone after the advantageous zone ends with the end of the AT2 state, or one transitioned from the normal zone for the first time after the setting is changed.Even if all data related to the AT is initialized at the end of the advantageous zone, it is possible to identify whether the advantageous zone is one transitioned from the normal zone after the advantageous zone ends with the end of the AT2 state, or one transitioned from the normal zone for the first time after the setting is changed.

[0154] [Regarding control at the start of CZ1 state] Next, the control at the start of the CZ1 state will be described with reference to FIG. 9 and FIG.

[0155] As shown in Fig. 9, the main control unit 41 controls the next game to CZ1 state after passing through the normal state and ending the premonition state. At this time, the CZ·AT signal is switched from OFF to ON, and the CZ·AT LED 19a is switched from OFF to ON. Note that the AT signal remains OFF, and the AT LED 19b also remains OFF.

[0156] In addition, when the CZ1 state starts, the sub-control unit 91 switches from the normal effect executed in the normal state and the precursor state to the CZ1 effect. The normal effect is an effect in which a normal background image or the like is displayed, and the CZ1 effect is an effect in which a CZ1 background image or the like specific to the CZ1 state is displayed.

[0157] After that, if the AT lottery is won at the end of the CZ1 state, the main control unit 41 controls the next game to the AT1 state. At this time, the CZ·AT signal is maintained in the ON state, the AT signal is switched to the ON state, the CZ·AT LED 19a is maintained in the ON state, and the AT LED 19b is switched from the OFF state to the ON state.

[0158] In addition, the sub-control unit 91 switches from the CZ1 effect to the AT1 effect when the AT1 state starts. The AT1 effect is an effect in which an AT1 background image specific to the AT1 state is displayed. In addition, at the start of the AT1 effect, the acquired number counter value, which counts the number of acquired coins during a series of ATs, is reset to 0, and an acquired number notification is started, which displays the acquired number counter value.

[0159] On the other hand, if the AT lottery has not been won at the end of the CZ1 state, the main control unit 41 controls the next game to the normal state. At this time, the CZ·AT signal and the AT signal are switched from the on state to the off state, and the CZ·AT LED 19a and the AT LED 19b are switched from the lit state to the non-lit state. In addition, the sub-control unit 91 switches from the CZ1 presentation to the normal presentation when the CZ1 state ends.

[0160] When the condition is achieved in the condition determination game in the AT1 state, the main control unit 41 controls the next game to the AT2 state. At this time, the CZ AT signal and the AT signal are kept on, and the CZ AT LED 19a and the AT LED 19b are kept on.

[0161] In addition, the sub-control unit 91 switches from the AT1 effect to the AT2 effect when the AT2 state starts. The AT2 effect is an effect in which an AT2 background image specific to the AT2 state is displayed. Even when the AT2 effect starts, the acquired number counter value is carried over, and the acquired number notification also continues.

[0162] On the other hand, as shown in Fig. 10, if the condition is not achieved in the condition determination game in the AT1 state, the main control unit 41 controls the next game to the normal state. At this time, the CZ·AT signal and the AT signal are switched from the ON state to the OFF state, and the CZ·AT LED 19a and the AT LED 19b are switched from the ON state to the OFF state. In addition, the sub-control unit 91 switches from the AT1 effect to the normal effect when the AT1 state ends, and the notification of the number of winning coins also ends.

[0163] [Control when AT2 state ends] Next, the control at the time of ending the AT2 state will be described with reference to Figs.

[0164] As shown in Fig. 11, when the AT2 state ends and the advantageous zone is ended with the net increase in the number of coins in the advantageous zone being equal to or less than the upper limit number, the main control unit 41 transitions to the normal zone from the next game. At this time, the CZ·AT signal and the AT signal are switched from the ON state to the OFF state, and the CZ·AT LED 19a and the AT LED 19b are switched from the ON state to the OFF state.

[0165] Furthermore, with the end of the AT2 state, the sub-control unit 91 ends the AT2 presentation (Fig. 18(a)), executes a result notification presentation (Fig. 18(b)) that notifies the results such as the net increase in number of coins during the series of AT periods (the period from the AT1 state) and the number of games controlled by the AT, and accordingly ends the notification of the number of coins won. Thereafter, in response to the start operation of the next game, the result notification presentation (Fig. 18(b)) is switched to a standby presentation (Fig. 18(c)). The standby presentation is a presentation in which standby images and the like are displayed.

[0166] After that, when the advantageous zone transition role is won in the normal zone, the main control unit 41 performs an AT lottery, ends the normal zone, starts the advantageous zone from the next game, and controls the CZ2 state when the advantageous zone starts. At this time, the CZ·AT signal is switched from the OFF state to the ON state, and the CZ·AT LED 19a is switched from the non-illuminated state to the illuminated state. Note that the AT signal remains in the OFF state, and the AT LED 19b also remains in the non-illuminated state.

[0167] In addition, the sub-control unit 91 switches from the standby effect (FIG. 18(c)) to the CZ2 introduction effect (FIG. 18(d)) with the start of the CZ2 state. The CZ2 introduction effect is an effect that suggests that the CZ2 state will start.

[0168] The main control unit 41 performs an AT lottery based on the result of the internal lottery at the start of the first game in the CZ2 state, and if the AT lottery is won at the end of the CZ2 state, that is, if the AT lottery is won at the time of the transition to the advantageous zone or the AT lottery for the first game in the CZ2 state, it controls the next game to the AT2 state. At this time, the CZ AT signal is kept on, and the AT signal is switched from the off state to the on state, the CZ AT LED 19a is kept on, and the AT LED 19b is switched from the unlit state to the lit state.

[0169] In addition, when the sub-control unit 91 wins either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ2 state, the sub-control unit 91 switches from the CZ2 introduction presentation (FIG. 18(d)) to the CZ2 presentation (normal) (FIG. 18(e)) triggered by the start operation of the first game in the CZ2 state. The CZ2 presentation (normal) is a presentation in which a CZ2 normal background image specific to the CZ2 state is displayed. Then, the sub-control unit 91 switches from the CZ2 presentation (normal) (FIG. 18(e)) to the AT2 presentation (FIG. 18(a)) with the start of the AT2 state. The acquired number counter value is carried over without being initialized even if the advantageous zone ends at the end of the previous AT2 state, and with the start of the AT2 presentation, the acquired number notification is started based on the acquired number counter value carried over and counted from the end of the previous AT2 state.

[0170] On the other hand, as shown in Figures 13 and 14, if the player has not won the AT lottery at the end of the CZ2 state, that is, if the player has not won either the AT lottery at the time of the transition to the advantageous zone or the AT lottery for the first game in the CZ2 state, the main control unit 41 controls the game to the normal state from the next game. At this time, the CZ AT signal is switched from the ON state to the OFF state, and the CZ AT LED 19a is switched from the ON state to the OFF state. Note that the AT signal remains OFF, and the AT LED 19b also remains OFF.

[0171] In addition, the sub-control unit 91 counts the number of consecutive AT2 states, which is the number of times that the AT2 state continues after the AT1 state without a normal state in between. The number of consecutive AT2 states is not initialized even when the advantageous period ends and control is switched to the normal period, and as long as the AT2 state continues without a normal state in between, the number of consecutive AT2 states is counted without interruption even if the normal period is in between.

[0172] Then, when the sub-control unit 91 does not win either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ2 state, and the number of consecutive AT2 wins is less than 20, the sub-control unit 91 switches from the CZ2 introduction presentation (Fig. 18(d)) to the CZ2 presentation (normal) (Fig. 18(e)) upon the start operation of the first game in the CZ2 state, as shown in Fig. 13. Then, with the end of the CZ2 state, the sub-control unit 91 switches from the CZ2 presentation (normal) (Fig. 18(e)) to the normal presentation (Fig. 18(f)).

[0173] In addition, when the player does not win either the AT lottery at the time of the transition to the advantageous zone or the AT lottery for the first game in the CZ2 state, if the number of consecutive AT2 wins is 20 or more, the sub-control unit 91 switches from the CZ2 introduction effect (FIG. 19(d)) to the CZ2 effect (ED) (FIG. 19(e)) as a trigger for the start operation of the first game in the CZ2 state, as shown in FIG. 14. The CZ2 effect (ED) is an effect unique to the CZ2 state, but has a different presentation form from the CZ2 effect (normal), and is an effect in which an ending image or the like is displayed that suggests the end of the period in which a series of ATs are occurring consecutively (the period in which the AT2 state continues without a normal state after the AT1 state). Then, the sub-control unit 91 switches from the CZ2 effect (ED) (FIG. 19(e)) to the normal effect (FIG. 19(f)) with the end of the CZ2 state.

[0174] As shown in Fig. 12, when the AT2 state ends and the advantageous zone continues, the main control unit 41 controls the next game to the preparation state. At this time, the CZ·AT signal and the AT signal are switched from the ON state to the OFF state, as in the case of the advantageous zone ending, and the CZ·AT LED 19a and the AT LED 19b are switched from the ON state to the OFF state.

[0175] In addition, when the AT2 state ends, the sub-control unit 91 ends the AT2 presentation (FIG. 18(a)), executes the result notification presentation (FIG. 18(b)), and ends the notification of the number of acquired coins. After that, when the start operation of the next game is triggered, the presentation is switched from the result notification presentation (FIG. 18(b)) to the standby presentation (FIG. 18(c)) in the same way as when the normal section is entered.

[0176] After that, when the advantageous zone transition role is won in the preparation state, the main control unit 41 performs the AT lottery, ends the preparation state, and controls the next game to the CZ2 state. At this time, the CZ·AT signal is switched from the OFF state to the ON state, and the CZ·AT LED 19a is switched from the non-illuminated state to the illuminated state. Note that the AT signal remains in the OFF state, and the AT LED 19b also remains in the non-illuminated state.

[0177] In addition, the sub-control unit 91 switches from the waiting presentation (Figure 18(c)) to the CZ2 introduction presentation (Figure 18(d)) when the CZ2 state begins, similar to when transitioning to the advantageous zone.

[0178] The main control unit 41 performs an AT lottery based on the result of the internal lottery at the start of the first game in the CZ2 state, and if the AT lottery is won at the end of the CZ2 state, that is, if the AT lottery is won either at the end of the preparation state or in the AT lottery for the first game in the CZ2 state, it controls the next game to the AT2 state. At this time, the CZ AT signal is kept on, and the AT signal is switched from off to on, the CZ AT LED 19a is kept on, and the AT LED 19b is switched from unlit to lit.

[0179] Furthermore, if the sub-control unit 91 wins either the AT lottery at the end of the preparation state or the AT lottery for the first game in the CZ2 state, the sub-control unit 91 switches from the CZ2 introduction presentation (Fig. 18(d)) to the CZ2 presentation (normal) (Fig. 18(e)) in response to the start operation of the first game in the CZ2 state. Then, the sub-control unit 91 switches from the CZ2 presentation (normal) (Fig. 18(e)) to the AT2 presentation (Fig. 18(a)) in response to the start of the AT2 state. The acquired number counter value is carried over without being initialized even if the advantageous zone ends at the end of the previous AT2 state, and when the AT2 presentation starts, an announcement of the acquired number of coins is started based on the acquired number counter value carried over and counted from the end of the previous AT2 state.

[0180] On the other hand, as shown in Figures 15 and 16, if the player has not won the AT lottery at the end of the CZ2 state, that is, if the player has not won either the AT lottery at the end of the preparation state or the AT lottery for the first game in the CZ2 state, the main control unit 41 controls the game to the normal state from the next game. At this time, the CZ AT signal is switched from the ON state to the OFF state, and the CZ AT LED 19a is switched from the ON state to the OFF state. Note that the AT signal remains OFF, and the AT LED 19b also remains OFF.

[0181] Furthermore, when the player does not win either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ2 state, and the number of consecutive AT2 wins is less than 20, the sub-control unit 91 switches from the CZ2 introduction presentation (Fig. 18(d)) to the CZ2 presentation (normal) (Fig. 18(e)) upon the start operation of the first game in the CZ2 state, as shown in Fig. 15. Then, the sub-control unit 91 switches from the CZ2 presentation (normal) (Fig. 18(e)) to the normal presentation (Fig. 18(f)) upon the end of the CZ2 state.

[0182] In addition, when the player does not win either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ2 state, if the number of consecutive AT2 times is 20 or more, the sub-control unit 91 switches from the CZ2 introduction presentation (Fig. 19(d)) to the CZ2 presentation (ED) (Fig. 19(e)) upon the start operation of the first game in the CZ2 state, as shown in Fig. 16. Then, the sub-control unit 91 switches from the CZ2 presentation (ED) (Fig. 19(e)) to the normal presentation (Fig. 19(f)) with the end of the CZ2 state.

[0183] As shown in FIG. 17, even if the main control unit 41 controls the ED state as described above by adding the number of remaining games, the net increase in the advantageous zone exceeds the upper limit, the AT2 state ends, and the advantageous zone ends, the next game is transitioned to the normal zone. At this time, the sub-control unit 91 starts the ED performance (FIG. 20(a)) with the start of the ED state, and ends the ED performance (FIG. 20(a)) with the end of the AT2 state, and executes the result notification / advantageous zone end performance (FIG. 20(b)) which notifies the fact that the advantageous zone ends as the net increase in the number of coins exceeds the upper limit of the advantageous zone, in addition to the results of the net increase in the number of coins during a series of AT periods (the period in which the AT2 state continues without a normal state after the AT1 state) and the number of games controlled by the AT, and ends the notification of the number of coins acquired. After that, the result notification / advantageous zone end performance (FIG. 20(b)) is switched to the normal performance (FIG. 20(c)) with the start operation of the next game as a trigger.

[0184] After that, when the advantageous zone transition role is won in the normal zone, the main control unit 41 performs an AT lottery and ends the normal zone, starts the advantageous zone from the next game, and controls to the CZ2 state with the start of the advantageous zone. Then, in the first game of the CZ2 state, the main control unit 41 performs an AT lottery based on the result of the internal lottery at the start of the game, and if the AT lottery is won at the end of the CZ2 state, that is, if either the AT lottery at the advantageous zone transition or the AT lottery for the first game of the CZ2 state is won, the main control unit 41 controls to the AT2 state from the next game.

[0185] Furthermore, if the sub-control unit 91 wins either the AT lottery when moving to the advantageous zone or the AT lottery for the first game in the CZ2 state, it executes a revival presentation (Fig. 20(d)) in response to the start operation of the first game in the CZ2 state, and then switches to a CZ2 presentation (normal) (Fig. 20(e)). After that, the sub-control unit 91 switches from the CZ2 presentation (normal) (Fig. 20(e)) to an AT2 presentation as the AT2 state begins. The acquired number counter value is carried over without being initialized even if the advantageous zone ends at the end of the previous AT2 state, and as the AT2 presentation begins, it starts notifying the number of acquired coins based on the acquired number counter value that has been carried over and counted since the end of the previous AT2 state.

[0186] On the other hand, if the main control unit 41 has not won the AT lottery at the end of the CZ2 state, i.e., if the player has not won either the AT lottery at the transition to the advantageous zone or the AT lottery for the first game in the CZ2 state, the main control unit 41 will control the next game to the normal state.

[0187] In addition, if the sub-control unit 91 does not win either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ2 state, it will continue to execute the normal effect (Figure 20(c)) without executing the revival effect (Figure 20(d)) or the CZ2 effect (normal) (Figure 20(e)).

[0188] In this embodiment, after the AT2 state ends, there are cases where the advantageous zone continues and the player is controlled to the CZ2 state, which is likely to be controlled to the AT2 state, and cases where the advantageous zone ends and the player transitions to the normal zone after the AT2 state ends, and when the advantageous zone is entered again, the player is controlled to the CZ2 state. When the advantageous zone continues and the player is controlled to the CZ2 state, the player is controlled to the CZ2 state via the preparation state. When the advantageous zone ends and the player transitions to the advantageous zone again after the AT2 state ends, there is always a waiting period before the CZ2 state starts after the AT2 state ends. However, even when the advantageous zone continues and the player is controlled to the CZ2 state, the CZ2 state does not start immediately, but is controlled to the CZ2 state via a preparation state for a predetermined period, which makes it difficult to determine whether the advantageous zone continues and the player is controlled to the CZ2 state, or whether the advantageous zone ends and the player is controlled to the CZ2 state after the advantageous zone ends.

[0189] In this embodiment, when a favorable zone transition role is won in the normal zone, the system transitions to the favorable zone, and even in the preparation state in which the system is controlled to the CZ2 state while the favorable zone continues, the preparation state is terminated and the system is controlled to the CZ2 state when a favorable zone transition role is won. If the system is controlled to the CZ2 state while the favorable zone continues, the system will be controlled to the CZ2 state at the same trigger as when the system is controlled to the CZ2 state after the favorable zone ends, making it difficult to determine whether the system was controlled to the CZ2 state while the favorable zone continued, or whether the system was controlled to the CZ2 state after the favorable zone ended.

[0190] In this embodiment, no control related to the AT is performed in the normal area, and even if the game is played in a stopping operation sequence in which a reel other than the left reel is the first stop, no penalty is given in relation to the AT and no warning notification is issued. However, even if the game is played in a stopping operation sequence in which a reel other than the left reel is the first stop in the preparation state, unlike the normal state, premonition state, CZ1 state, and CZ2 state, no penalty is given in relation to the AT, and as with the normal area, there is no change in the advantageous degree related to the AT, and no warning notification is issued for the AT, making it difficult to determine whether the advantageous area continues and the game is controlled to the CZ2 state, or whether the advantageous area ends and the game is controlled to the CZ2 state.

[0191] In this embodiment, when the AT2 state ends and the favorable period ends, the CZ·AT signal and the AT signal turn off once, and after the favorable period has been entered and the CZ2 state has started, the CZ·AT signal and the AT signal turn on again. However, even when the favorable period continues and the CZ2 state is controlled, the CZ·AT signal and the AT signal turn off once in the preparation state, and then turn off for at least one game, and after the CZ2 state starts, the CZ·AT signal and the AT signal turn on again. Even when the favorable period continues and the CZ2 state is controlled, the CZ·AT signal and the AT signal turn off once, just as when the favorable period ends and the CZ2 state is controlled, so that it is difficult to determine whether the favorable period continues and the CZ2 state is controlled, or whether the favorable period ends and the CZ2 state is controlled.

[0192] In particular, when switching from one state to another in which the CZ·AT signal is on, such as when transitioning from the CZ1 state to the AT1 state, when transitioning from the AT1 state to the AT2 state, or when transitioning from the CZ2 state to the AT2 state, while the favorable period is continuing, the CZ·AT signal will continue to be on. However, when switching from the AT2 state to the CZ2 state while the favorable period is continuing, a preparation state is inserted between them and the CZ·AT signal is temporarily turned off during that time, making it difficult to determine whether the favorable period continued and the CZ2 state was maintained, or whether the favorable period ended and the CZ2 state was maintained.

[0193] In this embodiment, when the AT2 state ends and the favorable zone ends, the CZ·AT LED 19a and the AT LED 19b go from the lit state to the non-lit state once, and after the favorable zone is entered and the CZ2 state begins, the CZ·AT LED 19a and the AT LED 19b go back to the lit state. However, even if the favorable zone continues and the CZ2 state is controlled, the CZ·AT LED 19a and the AT LED 19b go from the lit state to the non-lit state once in the preparation state, and then remain in the non-lit state for at least one game. After becoming unlit, LED 19a during CZ·AT and LED 19b during AT will turn on again after the CZ2 state begins. Even if the advantageous period continues and the game is controlled to the CZ2 state, LED 19a during CZ·AT and LED 19b during AT will turn off temporarily, just as in the case where the advantageous period ends and the game is controlled to the CZ2 state. This makes it difficult to determine whether the advantageous period continued and the game was controlled to the CZ2 state, or whether the advantageous period ended and the game was controlled to the CZ2 state.

[0194] In particular, when the advantageous period continues, LED 19a during CZ·AT will continue to be lit when switching from one state in which LED 19a during CZ·AT is lit to the other state, such as when transitioning from CZ1 state to AT1 state, when transitioning from AT1 state to AT2 state, when transitioning from CZ2 state to AT2 state, etc. However, when switching from AT2 state to CZ2 state in a situation in which the advantageous period continues, there is a preparation state in between, during which LED 19a during CZ·AT will be temporarily turned off, making it difficult to determine whether the advantageous period continued and the state was controlled to CZ2 state, or whether the advantageous period ended and the state was controlled to CZ2 state.

[0195] In this embodiment, the main control unit 41 conducts a stock lottery to determine whether or not to grant the right to control back to the AT2 state when a stock lottery target role (a lottery role corresponding to FC5 to 7) is won in the AT2 state, and if the stock lottery is won, the right to win the AT is stocked, and the sub-control unit 91 notifies the player when the right to win the AT is stocked and notifies the player in an identifiable manner of the number of remaining rights to win the AT. If the right to the AT is stocked at the end of the AT2 state, the game is controlled to return to the AT2 state from the next game without going through the preparation state or CZ2 state, and in a situation where it is confirmed that the AT2 state will continue, the AT2 state can be continued promptly without any unnecessary period of time.

[0196] In this embodiment, when the right to win the AT is stocked, the fact is notified, and the number of remaining rights to win the AT is also notified in an identifiable manner, but it is not necessary to notify all rights in an identifiable manner, and only some rights may be notified in an identifiable manner. In such a configuration, only when the right to win the AT is notified in an identifiable manner, if the right to win the AT is stocked at the end of the AT2 state, the game may be controlled to the AT2 state again from the next game without going through the preparation state or CZ2 state, and if the right to win the AT is stocked but not notified in an identifiable manner, the game may be controlled to the AT2 state by consuming the stock after going through the preparation state or CZ2 state, and by using such a configuration, even if the AT2 state does not start immediately after the end of the AT2 state, the player can expect that the right to win the AT is stocked.

[0197] In this embodiment, the sub-control unit 91 has an acquired number counter value that counts the number of medals acquired during a series of ATs (the period during which the AT2 state continues without a normal state after the AT1 state), and executes an acquired number notification that notifies the number of medals acquired during a series of ATs based on the acquired number counter value in the AT1 performance during the AT1 state and the AT2 performance during the AT2 state. In addition, when the AT2 state ends and the advantageous zone ends and transitions to the normal zone, the acquired number counter value is carried over without being reset, and then, when the AT lottery is won during the advantageous zone transition or in the CZ2 state that is controlled first after the advantageous zone transition and the AT2 state is controlled, the acquired number notification is executed based on the acquired number counter value carried over and counted from the AT2 state before the advantageous zone ends, so that it is possible to make it appear that the AT2 state is occurring continuously even if the advantageous zone is interrupted.

[0198] In this embodiment, the number of won coins is notified in the AT1 performance during the AT1 state and in the AT2 performance during the AT2 state, but the number of won coins may also be notified in the CZ2 performance during the CZ2 state.

[0199] In this embodiment, when the AT2 state ends with the net increase in the number of coins in the advantageous zone being equal to or less than the upper limit number, and after the advantageous zone is ended, a new advantageous zone starts and the CZ2 state starts, the sub-control unit 91 executes a result notification effect (FIG. 18(b)) at the end of the AT2 state and the advantageous zone, and then executes a waiting effect (FIG. 18(c)) in the normal zone, just as in the case where the advantageous zone continues. When the CZ2 state starts, the waiting effect (FIG. 18(c)) is switched from the waiting effect (FIG. 18(c)) to the CZ2 introduction effect (FIG. 18(d)) and then to the CZ2 effect (normal) (FIG. 18(e)) or the CZ2 effect (ED) (FIG. 19(e)). However, as a result of the number of games being added, the sub-control unit 91 is controlled to the ED state, and the advantageous zone is started. When the net increase in the number of coins exceeds the upper limit, the AT2 state ends, and after the advantageous zone ends, a new advantageous zone begins and the CZ2 state begins, unlike when the advantageous zone continues, an ED presentation (Figure 20(a)) is executed as soon as the ED state control begins, and at the end of the AT2 state and the advantageous zone, in addition to the result notification, a result notification / advantageous zone end presentation (Figure 20(b)) is executed to notify the player that the net increase in the number of coins has exceeded the upper limit of the advantageous zone, and that the advantageous zone is ending. After that, a normal presentation is executed during the normal zone, and when the CZ2 state begins and the AT lottery is won, a revival presentation (Figure 20(d)) is executed and then the presentation switches to a CZ2 presentation (Figure 20(e)). In this way, when the net increase in the number of coins in the advantageous zone exceeds the upper limit number, ending the advantageous zone, and a new advantageous zone begins, the presentation mode is different from when the net increase in the number of coins in the advantageous zone does not exceed the upper limit number, ending the advantageous zone, and a new advantageous zone begins. This reduces the sense of discomfort caused by the AT2 state continuing even though the net increase in the number of coins in the advantageous zone has exceeded the upper limit number, ending the advantageous zone.

[0200] As shown in FIG. 22, when the net increase in the number of coins in the advantageous zone exceeds the upper limit number and the AT2 state ends, and after the advantageous zone ends, a new advantageous zone starts and the CZ2 state starts, and the AT lottery is won, at the end of the AT2 state and advantageous zone, the result notification / end of advantageous zone effect (FIG. 20(b)) is executed, and then in the normal zone, the normal effect (FIG. 20(c)) is executed, and in the CZ2 state after the transition to the advantageous zone, the normal effect (FIG. 20(c)) is continued to be executed. When the AT lottery is won in the CZ2 state and the AT2 state starts after the end of the CZ2 state, the normal effect (FIG. 20(c)) may be switched to the AT2 effect. With this configuration, when the net increase in the number of coins in the advantageous zone exceeds the upper limit number and the advantageous zone ends, the relationship with the subsequent AT2 state becomes weak, so that the discomfort of the AT2 state continuing even though the net increase in the number of coins in the advantageous zone exceeds the upper limit number and the advantageous zone ends can be reduced. In addition, in such a configuration, if the CZ2 state ends without winning the AT lottery after the transition to the favorable zone, the normal performance may be continued as it is. In addition, in such a configuration, when the AT lottery is won in the CZ2 state at the time of transition to the favorable zone or after the transition to the favorable zone and the AT2 state is controlled, it is preferable to reset the net increase number counter value to 0 and not carry over the number of coins acquired in the AT2 state before the end of the favorable zone. By adopting such a configuration, when the net increase number of coins in the favorable zone exceeds the upper limit number and the favorable zone ends, the relationship with the subsequent AT2 state becomes even weaker, so that the sense of incongruity of the AT2 state continuing anew can be further reduced even though the net increase number of coins in the favorable zone exceeds the upper limit number and the favorable zone ends.

[0201] In this embodiment, after the AT2 state ends, the advantageous zone ends and the game moves to the normal zone, and when the game moves to the advantageous zone again, the game may be controlled to the CZ2 state, which is likely to be controlled to the AT2 state. After the AT2 state ends, the advantageous zone ends and the game moves to the normal zone, and when the game moves to the advantageous zone again, the game may be controlled to the CZ2 state. In this case, the presentation mode of the CZ2 state is selected based on the game history in the advantageous zone that has ended, so that even if the advantageous zone is interrupted, it can be made to appear as if the AT2 state and the subsequent CZ2 state are occurring continuously.

[0202] Furthermore, in this embodiment, the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and a transition occurs again to an advantageous zone is selected based on the history of the AT2 state in the ended advantageous zone, so that even if the advantageous zone ends, it is possible to make it appear as if the previous AT2 state and the subsequent CZ2 state are occurring consecutively.

[0203] In this embodiment, the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and the game moves back to the advantageous zone is selected based on the history of the AT2 state in the ended advantageous zone. However, the same effect can be achieved as long as the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and the game moves back to the advantageous zone is selected based on at least the game history in the ended advantageous zone. For example, the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and the game moves back to the advantageous zone may be selected based on the history of the number of medals won (net increase) in the ended advantageous zone, the number of games continued in the advantageous zone, etc.

[0204] In addition, in this embodiment, the presentation mode of the CZ2 state controlled when the advantageous zone ends and transitions to another advantageous zone is selected based on the number of consecutive AT2s in the ended advantageous zone (the number of times the AT2 state continues without a normal state after the AT1 state), but it may also be selected based on the history of the AT state in the ended advantageous zone, such as the number of consecutive AT states including both the AT1 state and the AT2 state in the ended advantageous zone (the number of times the AT state continues without a normal state), the number of medals increased since the AT1 state began, the number of games controlled to the AT2 state without a normal state, the number of games controlled to the AT1 state or the AT2 state without a normal state after the AT1 state began, the number of times the number of games was added in the AT2 state, etc.

[0205] In this embodiment, the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and a transition is made to another advantageous zone is controlled such that the CZ2 presentation (ED) is selected only if the number of consecutive AT2 times (the number of times the AT2 state continues after the AT1 state without a normal state in between) in the ended advantageous zone is 20 or more, i.e., if the AT2 state continues for a long period of time, and by executing the CZ2 presentation (ED) in the CZ2 state, it can be recognized that the game has been controlled to the AT2 state for a long period of time.

[0206] In this embodiment, the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and transitions to another advantageous zone is configured so that the CZ2 presentation (ED) is selected only if the number of consecutive AT2 occurrences in the ended advantageous zone is 20 or more. However, even if the CZ2 presentation (ED) is selected only when the AT state continues for a long period of time, such as when the number of consecutive AT states including the AT1 state is a specified number or more, when the number of games controlled to AT2 in the ended advantageous zone is a specified number or more, or when the number of games controlled to the AT1 state and the AT2 state is a specified number or more, the CZ2 presentation (ED) is executed in the CZ2 state, allowing the player to recognize that they are being controlled to the AT2 state for a long period of time.

[0207] In addition, in this embodiment, with regard to the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and a transition is made to another advantageous zone, a specific presentation mode (CZ2 presentation (ED)) is selected only when the period during which the AT2 state continues in the ended advantageous zone is a specific period (20 times) or more; however, the configuration may also be such that a specific presentation mode is more likely to be selected when the period during which the AT2 state continues in the ended advantageous zone is a specific period (20 times) or more than when the period during which the AT2 state continues in the ended advantageous zone is less than a specific period (20 times); even with such a configuration, by executing a CZ2 presentation of a specific presentation mode in the CZ2 state, it is possible to recognize that the player is being controlled to the AT2 state for a long period of time.

[0208] In this embodiment, the presentation mode of the CZ2 state controlled when the advantageous zone is ended and transitioned to the advantageous zone again is selected based on the history of the AT2 state in the ended advantageous zone and the type of advantageous zone transition role that triggered transition to the advantageous zone again. Specifically, when the advantageous zone transition role is a role belonging to FC0 or FC1 that may not win the AT lottery, the CZ2 presentation (ED) may be selected, whereas when it is a role belonging to FC3 to FC7 that always wins the AT lottery, the CZ2 presentation (ED) is not selected, and the CZ2 presentation (normal) is always selected. In this way, when the advantageous zone is ended and transitioned to the normal zone, and the advantageous zone is transitioned to again, the presentation mode of the CZ2 state is selected based on the history of the AT2 state in the ended advantageous zone and the type of advantageous zone transition role that triggered transition to the advantageous zone again, so that the presentation mode according to the trigger of transition to the advantageous zone can be selected.

[0209] In this embodiment, the presentation mode of the CZ2 state, which is controlled when the favorable zone ends and a transition is made to another favorable zone, is selected based on the history of the AT2 state in the favorable zone where the state has ended, and whether or not the state will be controlled to the AT2 state after the CZ2 state ends, so that attention can be drawn to the presentation mode of the CZ2 state.

[0210] In addition, in this embodiment, an AT lottery is performed to determine whether or not to control to the AT2 state after the CZ2 state depending on the favorable zone transition role that ended the favorable zone and triggered a transition to the favorable zone again, and an AT lottery is performed to determine whether or not to control to the AT2 state after the CZ2 state depending on the result of an internal lottery in the first game in the CZ2 state.After the AT2 state ends, the favorable zone ends and transitions to the normal zone, and when the favorable zone is transitioned to again, the CZ2 state is controlled.In this case, the presentation mode of the CZ2 state is selected based on the results of both the AT lottery at the transition to the favorable zone and the AT lottery in the first game in the CZ2 state, so that the results of both the AT lottery at the transition to the favorable zone and the AT lottery in the first game in the CZ2 state can be reflected in the presentation mode of the CZ2 state.

[0211] Furthermore, in this embodiment, with regard to the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and a transition is made to the advantageous zone again, the CZ2 presentation (ED) is selected only if the AT2 state is not controlled after the end of the CZ2 state, and if the AT2 state is controlled, the CZ2 presentation (normal) is selected, so that it is possible to make it appear as if the AT2 state is occurring continuously even if the advantageous zone is interrupted.

[0212] In this embodiment, the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and the game moves back to the advantageous zone is configured so that the CZ2 presentation (ED) is selected only if the game is not controlled to the AT2 state after the end of the CZ2 state; however, the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and the game moves back to the advantageous zone may be configured so that if the game is not controlled to the AT2 state after the end of the CZ2 state, a specific presentation mode is more likely to be selected than if the game is controlled to the AT2 state after the end of the CZ2 state. In this configuration, if the game is not controlled to the AT2 state after the CZ2 state, a specific presentation mode is more likely to be selected in the CZ2 state, whereas if the game is controlled to the AT2 state, a specific presentation mode is less likely to be selected in the CZ2 state, making it appear as if the AT2 state is occurring continuously.

[0213] [Effect 1] In this embodiment, after the AT2 state ends, the advantageous zone ends and the game moves to the normal zone, and when the game moves to the advantageous zone again, the game may be controlled to the CZ2 state, which is likely to be controlled to the AT2 state. After the AT2 state ends, the advantageous zone ends and the game moves to the normal zone, and when the game moves to the advantageous zone again, the game may be controlled to the CZ2 state. In this case, the presentation mode of the CZ2 state is selected based on the game history in the advantageous zone that has ended, so that even if the advantageous zone is interrupted, it can be made to appear as if the AT2 state and the subsequent CZ2 state are occurring continuously.

[0214] In this embodiment, the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and a transition occurs again is selected based on the history of the AT2 state in the ended advantageous zone, so that even if the advantageous zone ends, it can be made to appear as if the previous AT2 state and the subsequent CZ2 state are occurring continuously.

[0215] In this embodiment, the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and a transition is made to another advantageous zone is controlled such that the CZ2 presentation (ED) is selected only if the number of consecutive AT2 times (the number of times the AT2 state continues after the AT1 state without a normal state in between) in the ended advantageous zone is 20 or more, i.e., if the AT2 state continues for a long period of time, and by executing the CZ2 presentation (ED) in the CZ2 state, it can be recognized that the game has been controlled to the AT2 state for a long period of time.

[0216] In this embodiment, after the advantageous state ends, the advantageous zone ends and the game transitions to the normal zone, and when the game transitions to the advantageous zone again, the CZ2 state presentation mode is selected based on the AT2 state history in the advantageous zone that ended and the type of advantageous zone transition role that triggered the transition to the advantageous zone again, so that the presentation mode can be selected according to the trigger for transitioning to the advantageous zone.

[0217] In this embodiment, the presentation mode of the CZ2 state, which is controlled when the favorable zone ends and a transition is made to another favorable zone, is selected based on the history of the AT2 state in the favorable zone where the state has ended, and whether or not the state will be controlled to the AT2 state after the CZ2 state ends, so that attention can be drawn to the presentation mode of the CZ2 state.

[0218] In addition, in this embodiment, an AT lottery is performed to determine whether or not to control to the AT2 state after the CZ2 state depending on the favorable zone transition role that ended the favorable zone and triggered a transition to the favorable zone again, and an AT lottery is performed to determine whether or not to control to the AT2 state after the CZ2 state depending on the result of an internal lottery in the first game in the CZ2 state.After the AT2 state ends, the favorable zone ends and transitions to the normal zone, and when the favorable zone is transitioned to again, the CZ2 state is controlled.In this case, the presentation mode of the CZ2 state is selected based on the results of both the AT lottery at the transition to the favorable zone and the AT lottery in the first game in the CZ2 state, so that the results of both the AT lottery at the transition to the favorable zone and the AT lottery in the first game in the CZ2 state can be reflected in the presentation mode of the CZ2 state.

[0219] Furthermore, in this embodiment, with regard to the presentation mode of the CZ2 state that is controlled when the advantageous zone ends and a transition is made to the advantageous zone again, the CZ2 presentation (ED) is selected only if the AT2 state is not controlled after the end of the CZ2 state, and if the AT2 state is controlled, the CZ2 presentation (normal) is selected, so that it is possible to make it appear as if the AT2 state is occurring continuously even if the advantageous zone is interrupted.

[0220] Although the first embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to this first embodiment, and it goes without saying that the present invention includes modifications and additions that do not deviate from the spirit of the present invention.

[0221] In the above embodiment 1, an example was described in which the present invention is applied to a slot machine in which the bet amount is set using medals and credits as gaming value, but the present invention may also be applied to a slot machine in which the bet amount is set using gaming balls as gaming value, or a medal-free slot machine in which the bet amount is set using only credits, without using medals as gaming value. EXAMPLES

[0222] Next, a slot machine according to a second embodiment of the present invention will be described with reference to the drawings. Since the hardware configuration of the slot machine of this embodiment is the same, the same reference numerals will be used for the description. Since the slot machine 1 of this embodiment includes a common configuration with the slot machine 1 of the first embodiment, the description will focus on the configuration that differs from the first embodiment, and the description of the common configuration will be omitted. Furthermore, regarding the common or similar configuration to the first embodiment, modified examples that can be applied to the first embodiment can also be applied to this embodiment.

[0223] [Regarding the transition of game zone and advantageous zone states] Next, the transition of the advantageous zone state in the game zone and the advantageous zone by the main control unit 41 of the slot machine 1 of this embodiment will be described with reference to FIG. 23 and FIG.

[0224] When a favorable zone transition role is selected by an internal lottery in a game played in the normal zone, the main control unit 41 transitions the game zone to the favorable zone from the next game. The favorable zone is composed of multiple types of game zone states, including a normal state, a premonition state, a CZ1 state, a CZ3 state, a CZ4 state, an AT3 state, an AT4 state, and a preparation state.

[0225] As shown in FIG. 24, the normal state is a state in which no navigation notification is performed, and is a relatively disadvantageous state for the player. The premonition state is a state in which the player transitions after the end of the normal state and in which no navigation notification is performed, but which always transitions to the CZ1 state after that, and in this respect is a more advantageous state for the player than the normal state. The CZ1 state is a state in which no navigation notification is performed, but which may transition to the AT3 state after that, and is a more advantageous state for the player than the normal state and the premonition state. The CZ3 state is a state in which no navigation notification is performed, but which may transition to the AT3 state after that, and is a more advantageous state for the player than the normal state and the premonition state. In addition, the CZ3 state is a more advantageous state for the player than the CZ1 state in that the probability of winning the AT lottery is higher than the CZ1 state. The CZ4 state is a state in which no navigation notification is performed, but which may transition to the AT4 state after that, and is a more advantageous state for the player than the normal state and the premonition state. Also, the CZ4 state is more advantageous to the player than the CZ1 state in that the probability of winning the AT lottery is higher than the CZ1 state and the CZ3 state, and furthermore, as described later, when the AT lottery is won, the CZ4 state transitions to the AT4 state, which is more advantageous than the AT3 state. In this embodiment, the CZ4 state is more advantageous than the CZ1 state and the CZ3 state in that the probability of winning the AT lottery is higher than the CZ1 state and the CZ3 state, and when the AT lottery is won, the transition to the AT4 state, which is more advantageous than the AT3 state, is more advantageous than the CZ1 state and the CZ3 state, but it is sufficient that the CZ4 state is more advantageous than the CZ1 state and the CZ3 state in at least one of the following points: the probability of winning the AT lottery is higher than the CZ1 state and the CZ3 state, the transition to the AT4 state, which is more advantageous than the AT3 state, when the AT lottery is won, and the proportion of winning the AT4 state out of the AT3 state and the AT4 state is higher than the CZ1 state and the CZ3 state when the AT lottery is won. The AT3 state is an AT state in which a navigation notification is performed, and is a more advantageous state for the player than the normal state, the premonition state, the CZ1 state, the CZ3 state, and the CZ4 state. The AT4 state is an AT state in which a navigation notification is performed, and is a more advantageous state for the player than the normal state, the premonition state, the CZ1 state, the CZ3 state, and the CZ4 state.In addition, the AT4 state is more advantageous to the player than the AT3 state in that the player can expect a larger increase in medals than the AT3 state, the player may be given the right to control the AT4 state again, and the player will always transition to the CZ4 state after the AT4 state ends. The preparation state is a state in which no navigation notification is performed, and is a state in which the player is controlled before the CZ4 state starts if the advantageous zone continues after the AT4 state ends.

[0226] Among these advantageous zone states, in the normal state, the premonition state, the CZ1 state, the CZ3 state, and the CZ4 state in which the navigation notification is not performed, a penalty is given when a game is played in a stop operation sequence in which a reel other than the left reel is the first stop. Specifically, in the normal state and the premonition state, the number of games ended, which will be described later, is not updated, and in the CZ3 state and the CZ4 state, the AT lottery is not performed. In addition, the sub-control unit 91 executes a warning notification to the effect that a penalty has been given when a game is played in a stop operation sequence in which a reel other than the left reel is the first stop in the normal state, the premonition state, the CZ1 state, the CZ3 state, and the CZ4 state, and to encourage a game to be played in a stop operation sequence in which the left reel is the first stop.

[0227] On the other hand, in the AT3 and AT4 states where the navigation notification is performed, even if a game is played in a stop operation sequence in which a reel other than the left reel is the first stop, no penalty is given and no warning is given. Also, in the preparation state, although the navigation notification is not performed, even if a game is played in a stop operation sequence in which a reel other than the left reel is the first stop, no penalty is given and no warning is given.

[0228] The main control unit 41 shifts the game zone to the advantageous zone by winning the advantageous zone shift role in the normal zone. At this time, it judges whether the game state is not in the inside or in the inside, and if it judges that it is not in the inside, it performs a mode lottery and a game number lottery and controls it to the normal state.

[0229] The main control unit 41 adds the number of games (called the number of normal games) since the control to the normal state for each game in the normal state, judges whether the number of normal games after the addition reaches the number of games to be ended determined by the game number lottery, and if the number of games to be ended has been reached, ends the normal state and controls the state to the premonition state for a predetermined period (16 to 32 games in this embodiment). Then, when the premonition state ends, controls the state to the CZ1 state.

[0230] The CZ1 state is controlled for a period of 20 games, during which the main control unit 41 performs an AT lottery to determine whether or not to control to the AT state each time an AT lottery target role is won. The winning probability of the AT lottery is set for each lottery trigger and FC assigned to the AT lottery target role, as shown in Figure 25, and whether or not to control to the AT state is determined by the winning probability corresponding to the lottery trigger and the FC of the AT lottery target role that is won.

[0231] The main control unit 41 ends the CZ1 state after 20 games have elapsed since the start of the CZ1 state. If the AT lottery is won before the CZ1 state ends, control is exercised to switch to the AT3 state from the next game. On the other hand, if the AT lottery is not won before the CZ1 state ends, the above-mentioned mode lottery and game number lottery are performed to determine the mode and end game number of the normal state thereafter, and control is exercised to switch to the normal state from the next game.

[0232] When the AT3 state starts, the main control unit 41 sets the initial value of the remaining number of games to 20. Then, the main control unit 41 subtracts the remaining number of games for each game, and ends the AT3 state when the remaining number of games becomes 0.

[0233] In addition, when the main control unit 41 is in the AT3 state, it conducts an add-on lottery to determine whether or not to add to the remaining number of games and the number of games to be added when an add-on target role (a lottery role corresponding to FC5 or FC6) is won, and if the add-on lottery is won, it adds the won number of games to the remaining number of games.

[0234] At the end of the AT3 state, the main control unit 41 determines whether or not the additional lottery has been won three or more times in the AT3 state, and if the additional lottery has not been won three or more times, it determines that the condition has not been met, and controls the game to the CZ3 state from the next game while continuing the advantageous zone.

[0235] The CZ3 state is controlled over a period of six games, during which the main control unit 41 performs an AT lottery to determine whether or not to control to the AT state each time an AT lottery target role is won.

[0236] The main control unit 41 ends the CZ3 state after six games have passed since the start of the CZ3 state. If the AT lottery is won before the CZ3 state ends, control is exercised to switch to the AT3 state from the next game. On the other hand, if the AT lottery is not won before the CZ3 state ends, the above-mentioned mode lottery and game number lottery are performed to determine the mode and end game number of the normal state thereafter, and control is exercised to switch to the normal state from the next game.

[0237] If the player wins the additional lottery three or more times at the end of the AT3 state, the main control unit 41 ends the advantageous zone and transitions the game zone to the normal zone as the condition is met. At this time, all data related to the AT (such as the net increase in the advantageous zone and the number of points accumulated since the start of the advantageous zone) is initialized.

[0238] In this embodiment, when the AT3 state ends, if the additional lottery is won three or more times in the AT3 state, the condition is fulfilled and the advantageous zone ends and the system is controlled to the CZ4 state as described below. However, it is also possible to have a configuration in which, for example, a previously presented task is accomplished, the results of an internal lottery satisfy certain conditions, the number of accumulated points becomes equal to or exceeds a specified value, etc., whereby the advantageous zone ends and the system is controlled to the CZ4 state as described below, or, as in Example 1, the condition is fulfilled in a specific condition determination game whereby the condition is fulfilled and the advantageous zone ends and the system is controlled to the CZ4 state as described below.

[0239] In addition, when the main control unit 41 determines that the gaming state is inside when a beneficial zone transition role is won in the normal zone and transitions to the beneficial zone, it controls the next game to the CZ4 state.

[0240] As explained in the first embodiment, when the BB is won during a non-internal state, the state always transitions to the advantageous zone, so that when the state is controlled to the normal zone during an internal state, the state always transitions to the state after the advantageous zone ends, not the state after the data related to the game (data indicating the game state, data indicating the game zone, BB winning flag, etc.) is initialized by changing the settings. Also, since the end condition of the advantageous zone is almost never satisfied in an advantageous zone state other than the AT3 state or the AT4 state, it is essentially the state when the AT3 state or the AT4 state ends and the state transitions to the normal zone.

[0241] For this reason, as mentioned above, when transitioning from the normal zone after the favorable zone ends with the end of the AT3 state to the favorable zone again, it will first be controlled to the CZ4 state, and then, at the end of the CZ4 state, if the player has won either the AT lottery held at the time of transition to the favorable zone or the AT lottery held in the first game of the CZ4 state, it will be controlled to the AT4 state, and if the player has not won either the AT lottery held at the time of transition to the favorable zone or the AT lottery held in the first game of the CZ4 state, it will be controlled to the normal state.

[0242] When the AT4 state starts, the main control unit 41 sets the initial value of the remaining number of games to 30. Then, the main control unit 41 subtracts the remaining number of games for each game, and ends the AT4 state when the remaining number of games becomes 0.

[0243] In addition, the main control unit 41 performs an add-on lottery to determine whether or not to add the remaining number of games and the number of games when an add-on target role (a lottery role corresponding to FC4-6) is won in the AT4 state, and if the add-on lottery is won, the won number of games is added to the remaining number of games. Even if an add-on target role is won in the AT4 state, if the remaining net increase in number of coins (upper limit number-net increase in number of coins during the advantageous zone) is less than a specific number (200 in this embodiment), an add-on lottery is not performed, and the addition of the remaining number of games is limited. The specific number is a numerical value larger than the number of medals expected to increase by the addition of the number of games when an add-on target role (a lottery role corresponding to FC6) that can be expected to add the largest number of games is won. For this reason, it becomes difficult to add the number of games in which the net increase in number of coins during the advantageous zone exceeds the upper limit number.

[0244] In this embodiment, when the target role for addition is won in the AT4 state, if the remaining net increase number (upper limit number-net increase number in the advantageous zone) is less than a specific number (200 in this embodiment), the lottery for addition is not performed. However, for example, the target role for addition is increased, or the probability of winning the lottery for addition is increased. In such a configuration, when the remaining net increase number is less than a specific number in the AT4 state, the control of the addition state is restricted, while the lottery for addition is performed when the target role for addition is won. Also, in a configuration that can be controlled to multiple types of addition states with different numbers of games expected to be added, when the remaining net increase number is less than a specific number in the AT4 state, only some types of addition states in which the number of games expected to be added is relatively large may be restricted.

[0245] In addition, the main control unit 41 performs a stock lottery to determine whether or not to grant the right to control again to the AT4 state when a stock lottery target role (a lottery role corresponding to FC5 to 7) is won in the AT4 state, and if the stock lottery is won, the right to win the AT is stocked. When the right to win the AT is stocked, the sub-control unit 91 notifies the fact and notifies the number of remaining AT winning rights in an identifiable manner. In addition, even if a stock lottery target role is won in the AT4 state, if the remaining net increase in the number of coins (upper limit number-net increase in the number of coins in the advantageous zone) is less than a specific number (200 in this embodiment), the stock lottery is not performed, and the control of the AT4 state again is restricted.

[0246] When the number of remaining games becomes 0 in the AT4 state, the main control unit 41 ends the AT4 state. At this time, if the right to win the AT is stocked, the stocked right to win the AT is subtracted by 1, and the control is again made to the AT4 state from the next game. Also, if the right to win the AT is not stocked, it is determined whether the remaining net increase in number (upper limit number-net increase in number in the advantageous zone) is a specific number (200 in this embodiment) or less, and if the remaining net increase in number is the specific number or less, the advantageous zone is ended and the game zone is shifted to the normal zone. At this time, all data related to the AT (net increase in number in the advantageous zone, number of points accumulated since the start of the advantageous zone, etc.) are initialized. Also, if the right to win the AT is not stocked and the remaining net increase in number is not the specific number or less (if it exceeds the specific number), the control is made to the preparation state from the next game while continuing the advantageous zone.

[0247] In this way, it is determined whether the remaining net increase in the number of coins (maximum number of coins - net increase in the advantageous zone) at the end of the AT4 state is less than a specific number (200 in this embodiment), and if the remaining net increase in the number of coins is less than the specific number, the advantageous zone is ended and the game zone is transitioned to the normal zone.This prevents the net increase in the number of coins in the advantageous zone exceeding the maximum number of coins during the AT4 state, thereby meeting the conditions for ending the advantageous zone and suddenly ending the AT4 state, or restricting the addition of the remaining number of games through an additional lottery or the granting of rights to the AT4 state through a stock lottery so as not to reach the maximum number of coins.

[0248] Also, when the remaining net increase in number of coins (maximum number of coins - net increase in number of coins during the favorable zone) is below a specific number (200 in this embodiment), an additional lottery may be won, and a large number of games may be added at once, resulting in an increase in medals of a specific number or more. Even in a situation where an increase in medals of a specific number or more is not expected due to the addition of the number of games, the game may be controlled to the AT4 state again when the remaining net increase in number of coins is below a specific number due to the right to win the AT previously stocked. In such a case, even before the number of remaining games becomes 0 in the AT4 state, the net increase in number of coins in the favorable zone may exceed the maximum number of coins, and the end condition 1 of the favorable zone may be established.

[0249] For this reason, when the result of adding the number of remaining games in the additional lottery is that the sum of the net increase in the current advantageous zone and the net increase expected to increase based on the current number of remaining games and the stocked AT rights exceeds the upper limit, the main control unit 41 controls to the ED state, and continues the AT4 state regardless of the number of remaining games until the net increase in the advantageous zone exceeds the upper limit and the end condition 1 of the advantageous zone is satisfied, and ends the AT4 state together with the advantageous zone when the end condition 1 is satisfied. In such a case, the main control unit 41 ends the AT4 state, ends the advantageous zone, and transitions the game zone to the normal zone. In addition, it initializes all data related to the AT (the net increase in the advantageous zone, the number of points accumulated since the start of the advantageous zone, etc.). In addition, when the sub-control unit 91 controls to the ED state, it executes an ED performance that is different from the AT4 performance described later. In the ED performance, the number of remaining games and the number of stocked AT winning rights displayed in the AT4 performance are not displayed, and the remaining increase in the number of medals until the end condition 1 is satisfied is notified.

[0250] When the advantageous zone transition role is won in the preparation state, the main control unit 41 performs an AT lottery, ends the preparation state, and controls the next game to the CZ4 state. The preparation state ends when the advantageous zone transition role is won, so it is controlled for a period of at least one game.

[0251] The CZ4 state is controlled over a period of four games, and the main control unit 41 performs an AT lottery in the first game of the CZ4 state. When the CZ4 state is ended after four games have elapsed since the start of the CZ4 state, if the player wins either the AT lottery performed at the start of the preparation state or the AT lottery performed in the first game of the CZ4 state, the main control unit 41 ends the CZ4 state and controls the game to the AT4 state from the next game. On the other hand, if the player does not win either the AT lottery performed at the start of the preparation state or the AT lottery performed in the first game of the CZ4 state, the main control unit 41 ends the CZ4 state and performs the above-mentioned mode lottery and game number lottery to determine the mode and end game number of the normal state thereafter, and controls the game to the normal state from the next game.

[0252] In addition, if the main control unit 41 determines that the game state is internal when a beneficial zone transition role is won in the normal zone and the game transitions to the beneficial zone, it conducts an AT lottery, controls the game to the CZ4 state from the next game, and conducts an AT lottery in the first game in the CZ4 state.

[0253] As mentioned above, the internal control to the normal zone always occurs after the end of the advantageous zone. In addition, the condition for the end of the advantageous zone is almost never met in advantageous zone states other than AT3 and AT4 states, so it is essentially the end of the AT3 and AT4 states and the transition to the normal zone.

[0254] For this reason, when the AT4 state ends and the player transitions from the normal zone to the favorable zone again after the favorable zone ends, the player will first be controlled to the CZ4 state, and then, at the end of the CZ4 state, if the player has won either the AT lottery held at the time of transition to the favorable zone or the AT lottery held in the first game of the CZ4 state, the player will be controlled to the AT4 state, and if the player has not won either the AT lottery held at the time of transition to the favorable zone or the AT lottery held in the first game of the CZ4 state, the player will be controlled to the normal state.

[0255] [About the AT lottery] In this embodiment, as shown in FIG. 25, the AT lottery is triggered by the winning of a role eligible for AT selection in the CZ1 state which is controlled through the normal state and the premonition state (CZ1 state), the winning of a role eligible for AT selection in the CZ3 state which is controlled after the end of the AT3 state (CZ3 state), the winning of a role that transitions from the normal zone to the advantageous zone after the advantageous zone ends with the end of the AT3 state and AT4 state (at the time of transition to advantageous zone (inside)), the winning of a role that transitions from the preparation state to the CZ4 state while the advantageous zone continues after the end of the AT4 state (at the end of preparation state (winning of advantageous zone transition role)), and the first game in the CZ4 state (CZ4 state).

[0256] As shown in FIG. 25, in the AT lottery in the CZ1 state, the target AT state is the AT3 state, and when the target role for the AT lottery belongs to FC1 (when a 1-piece small role is won), the winning probability is 2.5%, when the target role for the AT lottery belongs to FC2 (when a normal replay is won), the winning probability is 5%, when the target role for the AT lottery belongs to FC3 (when a rare small role D is won), the winning probability is 6.25%, when the target role for the AT lottery belongs to FC4 (when a rare small role C is won), the winning probability is 12.5%, when the target role for the AT lottery belongs to FC5 (when a rare small role B is won), the winning probability is 25%, when the target role for the AT lottery belongs to FC6 (when a rare replay is won), the winning probability is 50%, and when the target role for the AT lottery belongs to FC7 (when a rare small role A is won), the winning probability is set to 100%.

[0257] Also, as shown in Figure 25, in the AT lottery in the CZ3 state, the target AT state is the AT3 state, and when the target role for the AT lottery belongs to FC3 to FC7 (when rare replay, rare small role A, rare small role B, rare small role C, or rare small role D is won), the winning probability is set to 100%.

[0258] Also, as shown in Figure 25, in the AT lottery during the transition to the favorable zone (inside), the target AT state is the AT4 state, and when the favorable zone transition role belongs to FC0 or FC1 (when the push order role or 1-coin small role is won), the winning probability is set to 60%, and when the favorable zone transition role belongs to FC3 to FC7 (when the rare replay, rare small role A, rare small role B, rare small role C, or rare small role D is won), the winning probability is set to 100%.

[0259] Also, as shown in Figure 25, in the AT lottery at the end of the preparation state (winning the advantageous zone transition role), the target AT state is the AT4 state, and when the advantageous zone transition role belongs to FC0 or FC1 (when the push order role or 1-coin small role is won), the winning probability is set to 60%, and when the advantageous zone transition role belongs to FC3 to FC7 (when the rare replay, rare small role A, rare small role B, rare small role C, or rare small role D is won), the winning probability is set to 100%.

[0260] Also, as shown in FIG. 25, in the AT lottery for the first game in the CZ4 state after the AT4 state ends, the target AT state is the AT4 state, and if the result of the internal lottery in that game belongs to FC0 to FC2 (when the push order role, 1-coin minor role, or normal replay is won), the winning probability is set to 70%, and if the result of the internal lottery in that game belongs to FC3 to FC7 (when the rare replay, rare minor role A, rare minor role B, rare minor role C, or rare minor role D is won), the winning probability is set to 100%.

[0261] In this embodiment, the AT lottery is held in any of the following states: the CZ4 state, which is controlled at the start of the advantageous zone transitioned from the normal zone after the advantageous zone ends with the end of the AT4 state; the CZ1 state, which is controlled after the normal state and premonition state have passed after the end of the CZ4 state; and the CZ3 state. However, if the AT lottery is won in the CZ1 state or CZ3 state, the player is controlled to the AT3 state, whereas if the AT lottery is won in the CZ4 state, the player is controlled to the AT4 state, which is relatively more advantageous than the AT3 state. After the advantageous zone starts and the CZ4 state ends, the player can be controlled to the AT4 state after the AT3 state, in which more medals can be expected to be won than in the AT3 state. However, if the advantageous zone has ended at the end of the AT4 state, the player can expect to be controlled to the AT4 state, which is relatively more advantageous than the AT3 state, without passing through the AT3 state, when the advantageous zone starts thereafter.

[0262] In addition, the probability of winning the AT lottery is set higher in the CZ4 state than in the CZ1 and CZ3 states, and if the favorable zone ends when the AT4 state ends, it can be expected that when the favorable zone starts afterwards, the player will be controlled to the AT4 state, which is relatively more favorable than the AT3 state, without going through the AT3 state.

[0263] In this embodiment, the system is configured to be controlled to the CZ4 state at the start of the favorable zone transitioned from the normal zone after the favorable zone ends with the end of the AT4 state, and is not controlled to the CZ4 state at the start of the favorable zone transitioned to for the first time after the setting is changed. However, the system may also be configured to be controlled to the CZ4 state even at the start of the favorable zone transitioned to for the first time after the setting is changed.

[0264] In addition, in this embodiment, the AT lottery is conducted every time an AT lottery-eligible role is won in the CZ1 state and the CZ3 state, but the AT lottery may be conducted for every game in the CZ1 state and the CZ3 state, or the AT lottery may be conducted only for a specific game (for example, the first game) in the CZ1 state and the CZ3 state.

[0265] In addition, in this embodiment, the AT lottery is conducted only in the first game in the CZ4 state, but it may be configured to conduct the AT lottery in a specific game other than the first game in the CZ4 state, or to conduct the AT lottery for every game in the CZ4 state, or to conduct the AT lottery every time a role eligible for the AT lottery is won in the CZ4 state.

[0266] Furthermore, in this embodiment, the AT lottery is configured so that the AT3 state is the subject of the AT lottery in the CZ1 state and the CZ3 state, and the AT4 state is the subject of the AT lottery in the CZ4 state at the start of the favorable zone, but it is also possible to configure so that both the AT3 state and the AT4 state are the subject of the AT lottery in the CZ1 state and the CZ3 state, or so that both the AT3 state and the AT4 state are the subject of the AT lottery in the CZ4 state at the start of the favorable zone, or so that both the AT3 state and the AT4 state are the subject of the AT lottery in the CZ1 state and the CZ3 state, and in the CZ4 state at the start of the favorable zone. Even with such a configuration, for example, by setting the winning probability so that in the AT lottery for the CZ1 state and the CZ3 state, the rate of winning the AT3 state out of the AT3 state and the AT4 state is higher, and in the AT lottery for the CZ4 state at the start of the favorable zone, the rate of winning the AT4 state out of the AT3 state and the AT4 state is higher, if the favorable zone has ended at the end of the AT4 state, it can be expected that when the favorable zone starts thereafter, the player will be controlled to the AT4 state, which is relatively more favorable than the AT3 state, without passing through the AT3 state.

[0267] In addition, in this embodiment, after the transition to the favorable zone and the end of the CZ4 state, the AT lottery is not performed in the normal state and premonition state until it is controlled to the CZ1 state, but it may be configured to perform the AT lottery in the normal state and premonition state until it is controlled to the CZ1 state. Even in such a configuration, in the AT lottery in the normal state and premonition state, the AT lottery is configured to be configured so that only the AT3 state is won, or the winning probability is set so that the proportion of the AT3 state among the AT3 state and the AT4 state that is won is higher, and in the AT lottery in the CZ4 state at the start of the favorable zone, the AT lottery is configured so that only the AT4 state is won, or the winning probability is set so that the proportion of the AT4 state among the AT3 state and the AT4 state that is won is higher. In this way, if the favorable zone has ended at the end of the AT4 state, it can be expected that when the favorable zone starts thereafter, it will be controlled to the AT4 state, which is relatively more favorable than the AT3 state, without passing through the AT3 state.

[0268] In this embodiment, when the advantageous zone transition role that triggers the transition from the normal zone to the advantageous zone after the advantageous zone ends with the end of the AT4 state is won, the AT lottery is held in both the CZ1 state and the CZ3 state, which are controlled after the CZ4 state ends through the normal state and the premonition state. However, if the AT lottery is won in the CZ1 state or the CZ3 state, the player is controlled to the AT3 state, whereas if the AT lottery is won during the transition to the advantageous zone, the player is controlled to the AT4 state, which is relatively more advantageous than the AT3 state. After the advantageous zone begins and the CZ4 state ends, the player can be controlled to the AT4 state after the AT3 state, in which more medals can be expected to be won than in the AT3 state. However, if the advantageous zone has ended at the end of the AT4 state, when the advantageous zone starts thereafter, the player can expect to be controlled to the AT4 state, which is relatively more advantageous than the AT3 state, without passing through the AT3 state.

[0269] In addition, the probability of winning the AT lottery is set higher when transitioning to a favorable zone than in the CZ1 and CZ3 states, and if the favorable zone ends when the AT4 state ends, it can be expected that when the favorable zone begins thereafter, the player will be controlled to the AT4 state, which is relatively more favorable than the AT3 state, without passing through the AT3 state.

[0270] In this embodiment, an AT lottery is conducted when a favorable zone transition role is won, which triggers a transition from the normal zone to the favorable zone after the favorable zone ends with the end of the AT4 state, and an AT lottery is not conducted when a favorable zone transition role is won, which triggers a transition to the favorable zone for the first time after the setting is changed.However, an AT lottery may also be conducted when a favorable zone transition role is won, which triggers a transition to the favorable zone for the first time after the setting is changed.

[0271] Furthermore, in this embodiment, the AT lottery is configured so that the AT3 state is the subject of the AT lottery in the CZ1 state and the CZ3 state, and the AT4 state is the subject of the AT lottery when transitioning to an advantageous zone; however, the AT lottery may be configured so that both the AT3 state and the AT4 state are the subject of the AT lottery in the CZ1 state and the CZ3 state, or so that both the AT3 state and the AT4 state are the subject of the AT lottery when transitioning to an advantageous zone, or so that both the AT3 state and the AT4 state are the subject of the AT lottery in the CZ1 state and the CZ3 state, and the AT lottery when transitioning to an advantageous zone. Even with such a configuration, for example, by setting the winning probability so that in the AT lottery for the CZ1 and CZ3 states, the rate of winning the AT3 state out of the AT3 and AT4 states is high, and in the AT lottery at the time of transition to a favorable zone, the rate of winning the AT4 state out of the AT3 and AT4 states is high, if the favorable zone has ended at the end of the AT4 state, it can be expected that when the favorable zone begins thereafter, the player will be controlled to the AT4 state, which is relatively more favorable than the AT3 state, without passing through the AT3 state.

[0272] Furthermore, even if the AT lottery is performed in the normal state and premonition state until it is controlled to the CZ1 state as described above, the AT lottery in the normal state and premonition state is configured so that only the AT3 state is won, or the winning probability is set so that the proportion of the AT3 state among the AT3 state and the AT4 state is higher, and the AT lottery during the transition to the favorable zone is configured so that only the AT4 state is won, or the winning probability is set so that the proportion of the AT4 state among the AT3 state and the AT4 state is higher.By doing this, if the favorable zone ends when the AT4 state ends, it can be expected that when the favorable zone begins afterwards, it will be controlled to the AT4 state, which is relatively more favorable than the AT3 state, without passing through the AT3 state.

[0273] In this embodiment, the AT lottery is performed at the time of the transition to the advantageous zone (inside), and the probability of winning the advantageous zone transition role and winning the AT lottery is less than 50%. In other words, at the time of the transition to the advantageous zone, the probability of not being determined to be controlled in the AT state is higher than the probability of being determined to be controlled in the AT state, and the ratio of being determined to be controlled in the AT state at the same time as the transition to the advantageous zone is suppressed, so that excessive gambling is not encouraged. In addition, in the advantageous zone, there is a role that is the target of the AT lottery but is not a role that transitions to the advantageous zone (normal replay), and when the role is won in the normal zone, there is no transition to the advantageous zone and no AT lottery is performed, so that the normal zone is not as advantageous as the advantageous zone. In addition, for roles that win the AT lottery 100% when won, such as FC3 to FC7, a configuration may be made in which a role that is the target of the AT lottery in the advantageous zone and is not a role that transitions to the advantageous zone is provided, and by making such a configuration, the difference in the degree of advantage between the normal zone and the advantageous zone becomes even clearer.

[0274] In this embodiment, the AT lottery is held in any of the following states: the CZ4 state, in which control continues with the advantageous zone after the AT4 state ends, the CZ1 state, which is controlled via the normal state and premonition state after the CZ4 state ends, and the CZ3 state. However, if the AT lottery is won in the CZ1 state or CZ3 state, the player will be controlled to the AT3 state, whereas if the AT lottery is won in the CZ4 state, the player will be controlled to the AT4 state, which is relatively more advantageous than the AT3 state. Therefore, after the AT4 state ends, regardless of whether the advantageous zone has ended or not, the player can expect to be controlled to the AT4 state, which is relatively more advantageous than the AT3 state, without passing through the AT3 state.

[0275] In addition, the probability of winning the AT lottery is set higher in the CZ4 state than in the CZ1 and CZ3 states, and it can be expected that after the AT4 state ends, regardless of whether the advantageous zone has ended or not, the player will be controlled to the AT4 state, which is relatively more advantageous than the AT3 state, without passing through the AT3 state.

[0276] In this embodiment, the AT3 state is the subject of the AT lottery in the CZ1 state and the CZ3 state, and the AT4 state is the subject of the AT lottery in the CZ4 state after the AT4 state ends; however, it is also possible to configure the AT lottery in the CZ1 state and the CZ3 state to include both the AT3 state and the AT4 state as subjects of the AT lottery, or to configure the AT lottery in the CZ4 state after the AT4 state ends to include both the AT3 state and the AT4 state as subjects of the AT lottery, or to configure the AT lottery in the CZ1 state and the CZ3 state, and in the CZ4 state after the AT4 state ends to include both the AT3 state and the AT4 state as subjects of the AT lottery. Even with such a configuration, for example, by setting the winning probability so that in the AT lottery for the CZ1 state and the CZ3 state, the rate of winning the AT3 state out of the AT3 state and the AT4 state is higher, and in the AT lottery for the CZ4 state after the AT4 state ends, the rate of winning the AT4 state out of the AT3 state and the AT4 state is higher, it can be expected that after the AT4 state ends, regardless of whether the advantageous zone has ended or not, the player will be controlled to the AT4 state, which is relatively more advantageous than the AT3 state, without passing through the AT3 state.

[0277] Furthermore, even if the AT lottery is performed in the normal state and premonition state until it is controlled to the CZ1 state as described above, the AT lottery in the normal state and premonition state can be configured so that only the AT3 state is won, or the winning probability is set so that the proportion of winning the AT3 state among the AT3 state and the AT4 state is higher, and the AT lottery in the CZ4 state after the AT4 state ends can be configured so that only the AT4 state is won, or the winning probability is set so that the proportion of winning the AT4 state among the AT3 state and the AT4 state is higher.By doing this, after the AT4 state ends, regardless of whether the advantageous zone has ended or not, it can be expected that the player will be controlled to the AT4 state, which is relatively more advantageous than the AT3 state, without passing through the AT3 state.

[0278] In this embodiment, once the game is controlled to the normal state in the advantageous zone, the game will then be controlled to the CZ1 or CZ3 state, in which the AT lottery will be held. If the AT lottery is won at the end of the CZ1 or CZ3 state, the game will first be controlled to the relatively disadvantageous AT3 state, and only when the conditions are met in the AT3 state will the game be controlled to the AT4 state, which is more advantageous than the AT3 state.

[0279] On the other hand, once controlled to the AT4 state, after the AT4 state ends, it will be in the CZ4 state which is likely to be controlled to the AT4 state again, so being controlled to the AT4 state once can give the expectation that the AT4 state will continue.

[0280] In addition, when the conditions are met in the AT3 state and before being controlled to the CZ4 state which can be controlled to the AT4 state, the favorable zone ends and the net increase in the number of coins in the favorable zone is initialized. Therefore, even if the state is then controlled to the CZ4 state and the AT4 state continues for a long period of time, the net increase in the number of coins in the favorable zone is unlikely to exceed the upper limit. Therefore, if the net increase in the number of coins in the favorable zone exceeds the upper limit during the AT4 state, the condition for the end of the favorable zone is met, and the AT4 state suddenly ends, and the addition of the remaining number of games through an additional lottery or the granting of the right to the AT4 state through a stock lottery is restricted so as not to reach the upper limit.

[0281] In addition, in the AT4 state, if the net increase in the number of coins in the favorable zone exceeds the upper limit and the favorable zone ends with the AT4 state, if the remaining net increase in the number of coins at the end of the AT4 state falls below a specific number and the favorable zone ends, the data related to the AT will be initialized. However, after that, at the start of the favorable zone, the state will be changed to the CZ4 state, which is likely to be controlled to the AT4 state. Therefore, by being controlled to the AT4 state once, it can be expected that the AT4 state will continue even if the favorable zone ends midway.

[0282] Furthermore, in this embodiment, when transitioning to a favorable zone, if the favorable zone is one transitioned from a normal zone after the favorable zone ends with the end of the AT state, the main control unit 41 controls the zone to CZ4 state, whereas when transitioning from a normal zone to a favorable zone for the first time after a setting change, the main control unit 41 does not control the zone to CZ4 state at the start of the favorable zone, but controls the zone to the normal state, so that even if the gaming establishment changes the setting, the zone will not be intentionally controlled to the CZ4 state, which is favorable to the player.

[0283] In addition, the main control unit 41 determines whether the game state is inside or not inside at the time of transition to the advantageous zone, and thereby identifies whether the advantageous zone is one transitioned from the normal zone after the advantageous zone ends with the end of the AT4 state, or one transitioned from the normal zone for the first time after the setting is changed.Even if all data related to the AT is initialized at the end of the advantageous zone, it is possible to identify whether the advantageous zone is one transitioned from the normal zone after the advantageous zone ends with the end of the AT4 state, or one transitioned from the normal zone for the first time after the setting is changed.

[0284] [Regarding control at the start of CZ1 state] Next, the control at the start of the CZ1 state will be described with reference to FIG.

[0285] As shown in Fig. 26, after the normal state and the end of the premonition state, the main control unit 41 controls the next game to the CZ1 state. At this time, the CZ·AT signal is switched from the OFF state to the ON state, and the CZ·AT LED 19a is switched from the OFF state to the ON state. Note that the AT signal remains in the OFF state, and the AT LED 19b also remains in the OFF state.

[0286] In addition, when the CZ1 state starts, the sub-control unit 91 switches from the normal effect executed in the normal state and the premonition state to the CZ1 effect.

[0287] After that, if the AT lottery is won at the end of the CZ1 state, the main control unit 41 controls the next game to the AT3 state. At this time, the CZ·AT signal is kept on and the AT signal is switched on, the CZ·AT LED 19a is kept on and the AT LED 19b is switched on from the unlit state to the lit state.

[0288] In addition, the sub-control unit 91 switches from the CZ1 effect to the AT3 effect when the AT3 state starts. The AT3 effect is an effect in which an AT3 background image specific to the AT3 state is displayed. In addition, at the start of the AT3 effect, the acquired number counter value, which counts the number of acquired coins during a series of ATs, is reset to 0, and an acquired number notification is started, which displays the acquired number counter value.

[0289] On the other hand, if the player has not won the AT lottery at the end of the CZ1 state, the main control unit 41 controls the game to the normal state from the next game. At this time, the CZ·AT signal is switched from the ON state to the OFF state, and the CZ·AT LED 19a is switched from the ON state to the OFF state. The AT signal remains OFF, and the AT LED 19b also remains OFF. In addition, the sub-control unit 91 switches from the CZ1 presentation to the normal presentation when the CZ1 state ends.

[0290] [Control when exiting AT3 state] Next, the control at the start of the AT3 state will be described with reference to Figs.

[0291] 27, if the condition is not met at the end of the AT3 state, the main control unit 41 controls the next game to the CZ3 state. At this time, the CZ·AT signal is kept on and the AT signal is switched off, the CZ·AT LED 19a is kept on, and the AT LED 19b is switched from on to off.

[0292] In addition, the sub-control unit 91 ends the AT3 presentation when the AT3 state ends, executes a result notification presentation that notifies the results of the net increase in number of coins during the series of AT periods (the period from the first AT3 state) and the number of games controlled by the AT, and ends the announcement of the number of coins won. After that, the result notification presentation is switched from the result notification presentation to the CZ3 presentation when the start operation of the next game is initiated. The CZ3 presentation is a presentation in which a CZ3 background image specific to the CZ3 state is displayed.

[0293] After that, if the AT lottery is won at the end of the CZ3 state, the main control unit 41 controls the next game to the AT3 state. At this time, the CZ·AT signal is kept on and the AT signal is switched on, the CZ·AT LED 19a is kept on and the AT LED 19b is switched on from the unlit state to the lit state.

[0294] In addition, the sub-control unit 91 switches from the CZ3 effect to the AT3 effect when the AT3 state starts. In addition, the acquired number counter value is carried over, and at the start of the AT3 effect, the acquired number notification that displays the acquired number counter value is started.

[0295] On the other hand, as shown in Fig. 28, if the AT lottery has not been won at the end of the CZ3 state, the main control unit 41 controls the next game to the normal state. At this time, the CZ·AT signal is switched from the ON state to the OFF state, and the CZ·AT LED 19a is switched from the ON state to the OFF state. Note that the AT signal remains OFF, and the AT LED 19b also remains OFF.

[0296] As shown in Fig. 29, if the conditions are met at the end of the AT3 state, the main control unit 41 ends the advantageous period and transitions to the normal period from the next game. At this time, the CZ·AT signal and the AT signal are switched from the on state to the off state, and the CZ·AT LED 19a and the AT LED 19b are switched from the on state to the non-on state.

[0297] In addition, the sub-control unit 91 ends the AT3 presentation when the AT3 state ends, executes a result notification presentation to notify the results of the net increase in number of coins during the series of AT periods (the period from the first AT3 state) and the number of games controlled by the AT, and ends the announcement of the number of coins obtained. After that, the start operation of the next game is used as a trigger to switch from the result notification presentation to a standby presentation. The standby presentation is a presentation in which a standby image or the like is displayed.

[0298] After that, when the advantageous zone transition role is won in the normal zone, the main control unit 41 performs an AT lottery, ends the normal zone, starts the advantageous zone from the next game, and controls the state to CZ4 when the advantageous zone starts. At this time, the CZ·AT signal is switched from the OFF state to the ON state, and the CZ·AT LED 19a is switched from the non-illuminated state to the illuminated state. Note that the AT signal remains in the OFF state, and the AT LED 19b also remains in the non-illuminated state.

[0299] In addition, when the CZ4 state starts, the sub-control unit 91 switches from the standby effect to the CZ4 introduction effect. The CZ4 introduction effect is an effect that suggests that the CZ4 state will start.

[0300] The main control unit 41 performs an AT lottery based on the result of the internal lottery at the start of the first game in the CZ4 state, and if the AT lottery is won at the end of the CZ4 state, that is, if the AT lottery is won at the time of the transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, it controls the next game to the AT4 state. At this time, the CZ AT signal is kept on, and the AT signal is switched from the off state to the on state, the CZ AT LED 19a is kept on, and the AT LED 19b is switched from the unlit state to the lit state.

[0301] In addition, when the sub-control unit 91 wins either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, the sub-control unit 91 switches from the CZ4 introduction presentation to the CZ4 presentation (normal) with the start operation of the first game in the CZ4 state as a trigger. The CZ4 presentation (normal) is a presentation in which a CZ4 normal background image specific to the CZ4 state is displayed. Then, the sub-control unit 91 switches from the CZ4 presentation (normal) to the AT4 presentation with the start of the AT4 state. The acquired number counter value is carried over without being initialized even if the advantageous zone ends at the end of the previous AT3 state, and with the start of the AT4 presentation, the acquired number notification is started based on the acquired number counter value carried over and counted from the end of the previous AT3 state.

[0302] On the other hand, if the player has not won the AT lottery at the end of the CZ4 state, i.e., if the player has not won either the AT lottery at the time of the transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, the main control unit 41 controls the game to the normal state from the next game. At this time, the CZ·AT signal is switched from the ON state to the OFF state, and the CZ·AT LED 19a is switched from the ON state to the OFF state. Note that the AT signal remains OFF, and the AT LED 19b also remains OFF.

[0303] In addition, when the player does not win either the AT lottery at the time of the transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, the sub-control unit 91 switches from the CZ4 introduction effect to the CZ4 effect (normal) in response to the start operation of the first game in the CZ4 state. Then, the sub-control unit 91 switches from the CZ4 effect (normal) to the normal effect in response to the end of the CZ4 state.

[0304] [Regarding control when AT4 state ends] Next, the control at the time of ending the AT4 state will be described with reference to Figs.

[0305] As shown in Fig. 30, when the AT4 state ends and the advantageous zone is ended with the net increase in the number of coins in the advantageous zone being equal to or less than the upper limit number, the main control unit 41 transitions to the normal zone from the next game. At this time, the CZ·AT signal and the AT signal are switched from the ON state to the OFF state, and the CZ·AT LED 19a and the AT LED 19b are switched from the ON state to the OFF state.

[0306] In addition, the sub-control unit 91 ends the AT4 presentation when the AT4 state ends, executes a result notification presentation to notify the results of the net increase in number of coins during a series of AT periods (the period during which the AT3 state and the AT4 state continue without a normal state in between) and the number of games controlled by the AT, and ends the announcement of the number of coins won. After that, the start operation of the next game is used as a trigger to switch from the result notification presentation to a standby presentation. The standby presentation is a presentation in which a standby image or the like is displayed.

[0307] After that, when the advantageous zone transition role is won in the normal zone, the main control unit 41 performs an AT lottery, ends the normal zone, starts the advantageous zone from the next game, and controls the state to CZ4 when the advantageous zone starts. At this time, the CZ·AT signal is switched from the OFF state to the ON state, and the CZ·AT LED 19a is switched from the non-illuminated state to the illuminated state. Note that the AT signal remains in the OFF state, and the AT LED 19b also remains in the non-illuminated state.

[0308] In addition, the sub-control unit 91 switches from the standby presentation to the CZ4 introduction presentation when the CZ4 state begins.

[0309] The main control unit 41 performs an AT lottery based on the result of the internal lottery at the start of the first game in the CZ4 state, and if the AT lottery is won at the end of the CZ4 state, that is, if the AT lottery is won at the time of the transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, it controls the next game to the AT4 state. At this time, the CZ AT signal is kept on, and the AT signal is switched from the off state to the on state, the CZ AT LED 19a is kept on, and the AT LED 19b is switched from the unlit state to the lit state.

[0310] In addition, when the sub-control unit 91 wins either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, the sub-control unit 91 switches from the CZ4 introduction presentation to the CZ4 presentation (normal) with the start operation of the first game in the CZ4 state as a trigger. Then, the sub-control unit 91 switches from the CZ4 presentation to the AT4 presentation with the start of the AT4 state. The acquired number counter value is carried over without being initialized even if the advantageous zone ends at the end of the previous AT4 state, and with the start of the AT4 presentation, the acquired number notification is started based on the acquired number counter value carried over and counted from the end of the previous AT4 state.

[0311] On the other hand, as shown in Figures 32 and 33, if the player has not won the AT lottery at the end of the CZ4 state, that is, if the player has not won either the AT lottery at the time of the transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, the main control unit 41 controls the game to the normal state from the next game. At this time, the CZ AT signal is switched from the ON state to the OFF state, and the CZ AT LED 19a is switched from the ON state to the OFF state. Note that the AT signal remains OFF, and the AT LED 19b also remains OFF.

[0312] In addition, the sub-control unit 91 counts the number of consecutive ATs, which is the number of times that the AT3 state and the AT4 state continue without a normal state in between. The number of consecutive ATs is not initialized even when the advantageous period ends and control is returned to the normal period, and as long as the AT3 state and the AT4 state continue without a normal period in between, the number is counted without interruption even if the normal period is in between.

[0313] Then, when the sub-control unit 91 does not win either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, and the number of consecutive ATs is less than 20, the sub-control unit 91 switches from the CZ4 introduction presentation to the CZ4 presentation (normal) in response to the start operation of the first game in the CZ4 state, as shown in Fig. 32. Then, the sub-control unit 91 switches from the CZ4 presentation (normal) to the normal presentation with the end of the CZ4 state.

[0314] In addition, when the player does not win either the AT lottery at the time of the transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, if the number of consecutive ATs is 20 or more, the sub-control unit 91 switches from the CZ4 introduction effect to the CZ4 effect (ED) as a trigger of the start operation of the first game in the CZ4 state, as shown in FIG. 33. The CZ4 effect (ED) is an effect unique to the CZ4 state, but has a different effect mode from the CZ4 effect (normal), and is an effect in which an ending image or the like is displayed that suggests the end of the period in which a series of ATs are occurring consecutively (the period in which the AT3 state and the AT4 state are continuing without a normal state). Then, the sub-control unit 91 switches from the CZ4 effect (ED) to the normal effect with the end of the CZ4 state.

[0315] As shown in Fig. 31, when the AT4 state ends and the advantageous zone continues, the main control unit 41 controls the next game to the preparation state. At this time, the CZ·AT signal and the AT signal are switched from the ON state to the OFF state, as in the case of the advantageous zone ending, and the CZ·AT LED 19a and the AT LED 19b are switched from the ON state to the OFF state.

[0316] In addition, when the AT4 state ends, the sub-control unit 91 ends the AT4 presentation, executes the result notification presentation, and ends the notification of the number of acquired coins. After that, when the start operation of the next game is performed, the presentation is switched from the result notification presentation to the standby presentation, in the same manner as when the normal section is entered.

[0317] After that, when the advantageous zone transition role is won in the preparation state, the main control unit 41 performs the AT lottery, ends the preparation state, and controls the next game to the CZ4 state. At this time, the CZ AT signal is switched from the OFF state to the ON state, and the CZ AT LED 19a is switched from the non-illuminated state to the illuminated state. Note that the AT signal remains in the OFF state, and the AT LED 19b also remains in the non-illuminated state.

[0318] In addition, the sub-control unit 91 switches from the waiting presentation to the CZ4 introduction presentation when the CZ4 state begins, similar to when transitioning to the advantageous zone.

[0319] The main control unit 41 performs an AT lottery based on the result of the internal lottery at the start of the first game in the CZ4 state, and if the AT lottery is won at the end of the CZ4 state, that is, if the AT lottery is won either at the end of the preparation state or in the AT lottery for the first game in the CZ4 state, it controls the next game to the AT4 state. At this time, the CZ AT signal is kept on, and the AT signal is switched from off to on, the CZ AT LED 19a is kept on, and the AT LED 19b is switched from unlit to lit.

[0320] In addition, if the sub-control unit 91 wins either the AT lottery at the end of the preparation state or the AT lottery for the first game in the CZ4 state, the sub-control unit 91 switches from the CZ4 introduction presentation to the CZ4 presentation (normal) in response to the start operation of the first game in the CZ4 state. Then, the sub-control unit 91 switches from the CZ4 presentation (normal) to the AT4 presentation with the start of the AT4 state. The acquired number counter value is carried over without being initialized even if the advantageous zone ends at the end of the previous AT4 state, and with the start of the AT4 presentation, the acquired number notification is started based on the acquired number counter value carried over and counted from the end of the previous AT4 state.

[0321] On the other hand, as shown in Figures 34 and 35, if the player has not won the AT lottery at the end of the CZ4 state, that is, if the player has not won either the AT lottery at the end of the preparation state or the AT lottery for the first game in the CZ4 state, the main control unit 41 controls the game to the normal state from the next game. At this time, the CZ AT signal is switched from the ON state to the OFF state, and the CZ AT LED 19a is switched from the ON state to the OFF state. Note that the AT signal remains OFF, and the AT LED 19b also remains OFF.

[0322] In addition, when the player does not win either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, and the number of consecutive ATs is less than 20, the sub-control unit 91 switches from the CZ4 introduction presentation to the CZ4 presentation (normal) in response to the start operation of the first game in the CZ4 state, as shown in Fig. 34. Then, the sub-control unit 91 switches from the CZ4 presentation (normal) to the normal presentation when the CZ4 state ends.

[0323] In addition, when the player does not win either the AT lottery at the time of the transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, if the number of consecutive ATs is 20 or more, the sub-control unit 91 switches from the CZ4 introduction presentation to the CZ4 presentation (ED) in response to the start operation of the first game in the CZ4 state, as shown in Fig. 35. Then, the sub-control unit 91 switches from the CZ4 presentation (ED) to the normal presentation with the end of the CZ4 state.

[0324] As shown in FIG. 36, even if the main control unit 41 controls the ED state as described above by adding the number of remaining games, the net increase in the advantageous zone exceeds the upper limit, the AT4 state ends, and the advantageous zone ends, the next game will be transitioned to the normal zone. At this time, the sub-control unit 91 starts the ED performance when the ED state starts, ends the ED performance when the AT4 state ends, and executes the result notification / advantageous zone end performance to notify that the advantageous zone will end as the net increase in the number of coins exceeds the upper limit of the advantageous zone in addition to the results of the net increase in the number of coins during a series of AT periods (the period in which the AT3 state and the AT4 state are continuous without a normal state in between) and the number of games controlled by the AT, and ends the notification of the number of coins acquired. After that, the result notification / advantageous zone end performance is switched to the normal performance when the start operation of the next game is performed.

[0325] After that, when the advantageous zone transition role is won in the normal zone, the main control unit 41 performs an AT lottery and ends the normal zone, starts the advantageous zone from the next game, and controls to the CZ4 state with the start of the advantageous zone. Then, in the first game of the CZ4 state, the main control unit 41 performs an AT lottery based on the result of the internal lottery at the start of the game, and if the AT lottery is won at the end of the CZ4 state, that is, if either the AT lottery at the advantageous zone transition or the AT lottery for the first game of the CZ4 state is won, the next game is controlled to the AT4 state.

[0326] In addition, when the sub-control unit 91 wins either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, it executes a revival presentation triggered by the start operation of the first game in the CZ4 state, and then switches to the CZ4 presentation (normal). After that, the sub-control unit 91 switches from the CZ4 presentation (normal) to the AT4 presentation with the start of the AT4 state. The acquired number counter value is carried over without being initialized even if the advantageous zone ends at the end of the previous AT4 state, and with the start of the AT4 presentation, it starts announcing the number of acquired coins based on the acquired number counter value carried over and counted from the end of the previous AT4 state.

[0327] On the other hand, if the main control unit 41 has not won the AT lottery at the end of the CZ4 state, i.e., if the player has not won either the AT lottery at the transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, the main control unit 41 will control the next game to the normal state.

[0328] In addition, if the sub-control unit 91 does not win either the AT lottery at the time of transition to the advantageous zone or the AT lottery for the first game in the CZ4 state, it continues to execute the normal presentation without executing the revival presentation or the CZ4 presentation (normal).

[0329] In this embodiment, there are cases where, after the AT4 state ends, the advantageous zone is ended and the game moves to the normal zone, and when the game moves to the advantageous zone again, the game is controlled to the CZ4 state; when the AT4 state ends and the advantageous zone is controlled to the CZ4 state with a high possibility of being controlled to the AT4 state while the advantageous zone continues; and when the AT3 state ends and the game is controlled to the CZ3 state with a high possibility of being controlled to the AT3 state while the advantageous zone continues. When the advantageous zone is controlled to the CZ4 state while continuing, the game is controlled to the CZ4 state after passing through a preparation state. When the advantageous zone is controlled to the CZ4 state when the advantageous zone is ended and the game moves to the advantageous zone again after the AT4 state ends, a waiting period is always generated after the AT4 state ends before the CZ4 state starts. However, even when the advantageous zone is controlled to the CZ4 state while continuing, the CZ4 state does not start immediately, but is controlled to the CZ4 state after passing through a preparation state for a predetermined period, so that it is difficult to determine whether the advantageous zone is controlled to the CZ4 state while continuing, or whether the advantageous zone is controlled to the CZ4 state after the advantageous zone ends once.

[0330] On the other hand, if the advantageous zone continues after the AT3 state ends and the player is controlled to the CZ3 state, the player will be controlled to the CZ3 state without going through the preparation state, so if the advantageous zone continues after the AT3 state ends and the player is controlled to the CZ3 state, the player can quickly transition to the CZ3 state after the AT3 state ends.

[0331] The CZ4 state in this embodiment is a state in which the probability of winning the AT lottery is set higher than in the CZ3 state, and being controlled to the preparation state can give the player the expectation of being controlled to the AT4 state.

[0332] In this embodiment, the AT states include an AT3 state and an AT4 state in which it is expected that more medals will be won than in the AT3 state. When controlled from the CZ4 state to the AT state, it is controlled to the AT4 state, and when controlled from the CZ3 state to the AT state, it is controlled to the AT3 state. Therefore, by being controlled to the preparation state, it can be expected that it will be controlled to the more advantageous AT4 state.

[0333] In this embodiment, when controlled from the CZ4 state to the AT state, it is controlled to the AT4 state, and when controlled from the CZ3 state to the AT state, it is controlled to the AT3 state. However, it may also be configured so that when controlled from the CZ4 state to the AT state, it is more likely to be controlled to the AT3 state, or of the AT4 states, it is more likely to be controlled to the AT4 state, and when controlled from the CZ3 state to the AT state, it is more likely to be controlled to the AT3 state, or of the AT4 states, it is more likely to be controlled to the AT3 state. Even with such a configuration, it can be expected that it will be controlled to the more advantageous AT4 state by being controlled to the preparation state.

[0334] In this embodiment, an AT lottery is conducted when transitioning to a favorable zone, and if the AT lottery is won when transitioning to a favorable zone, the system is controlled to the AT4 state. This prevents the system from being controlled to an unintended type of AT state when transitioning to a favorable zone in the process of being controlled to the CZ4 state after the AT4 state ends and the system transitions to the favorable zone again after the favorable zone ends.

[0335] In this embodiment, if the AT lottery is won when transitioning to a favorable zone, the configuration is such that the player is controlled to the AT4 state; however, if the AT lottery is won when transitioning to a favorable zone, the configuration may be such that the player is more likely to be controlled to the AT4 state out of the AT3 state and the AT4 state. Even with this configuration, it is possible to prevent the player from being controlled to an unintended type of AT state when transitioning to a favorable zone in the process of being controlled to the CZ4 state after the AT4 state ends and the favorable zone ends and the player transitions to the favorable zone again.

[0336] In this embodiment, the number of games controlled to the CZ4 state is less than the number of games controlled to the CZ3 state, so even if the game is controlled to the preparation state after the end of the AT4 state, the period from whence the game passes through the CZ4 state until when it is controlled to the AT4 state is not redundant.

[0337] In this embodiment, the number of games in the CZ4 state and the number of games in the CZ3 state are fixed, but these numbers of games may also be variable. In such a configuration, it is sufficient that the expected value of the number of games in the CZ4 state is smaller than the expected value of the number of games in the CZ3 state. Even with such a configuration, when the AT4 state is controlled to the preparation state after the end of the AT4 state, the period from when the AT4 state is passed through the CZ4 state to when the AT4 state is controlled is not redundant.

[0338] In this embodiment, when a favorable zone transition role is won in the normal zone, the system transitions to the favorable zone, and even in the preparation state in which the system is controlled to the CZ4 state while the favorable zone continues, the preparation state is terminated and the system is controlled to the CZ4 state when a favorable zone transition role is won. If the system is controlled to the CZ4 state while the favorable zone continues, the system will be controlled to the CZ4 state at the same trigger as when the system is controlled to the CZ4 state after the favorable zone ends, making it difficult to determine whether the system was controlled to the CZ4 state while the favorable zone continued, or whether the system was controlled to the CZ4 state after the favorable zone ended.

[0339] In this embodiment, no control related to the AT is performed in the normal area, and even if the game is played in a stopping operation sequence in which a reel other than the left reel is the first stop, no penalty is given in relation to the AT and no warning notification is issued. However, even if the game is played in a stopping operation sequence in which a reel other than the left reel is the first stop in the preparation state, unlike the normal state, premonition state, CZ1 state, CZ3 state, and CZ4 state, no penalty is given in relation to the AT, and as with the normal area, there is no change in the advantageous degree related to the AT, and no warning notification is issued for the AT, making it difficult to determine whether the advantageous area continues and the game is controlled to the CZ4 state, or whether the advantageous area ends and the game is controlled to the CZ4 state.

[0340] In this embodiment, when the AT4 state ends and the favorable period ends, the CZ·AT signal and the AT signal turn off once, and after the favorable period has started and the CZ4 state has begun, the CZ·AT signal and the AT signal turn on again. However, even when the favorable period continues and the CZ4 state is controlled, the CZ·AT signal and the AT signal turn off once in the preparation state, and then turn off for at least one game, and after the CZ4 state begins, the CZ·AT signal and the AT signal turn on again. Even when the favorable period continues and the CZ4 state is controlled, the CZ·AT signal and the AT signal turn off once, just as when the favorable period ends and the CZ4 state is controlled, so that it is difficult to determine whether the favorable period continues and the CZ4 state is controlled, or whether the favorable period ends and the CZ4 state is controlled.

[0341] In particular, when the CZ·AT signal is switched from one state to another in which the CZ·AT signal is on, such as when transitioning from the CZ1 state to the AT3 state, when transitioning from the CZ3 state to the AT3 state, or when transitioning from the CZ4 state to the AT4 state, in a situation where the favorable period continues, the on state of the CZ·AT signal will continue. However, when switching from the AT4 state to the CZ4 state in a situation where the favorable period continues, a preparation state is inserted in between, during which the CZ·AT signal is temporarily turned off, making it difficult to determine whether the favorable period continued and the CZ4 state was maintained, or whether the favorable period ended and the CZ4 state was maintained.

[0342] In this embodiment, when the AT4 state ends and the favorable zone ends, the CZ·AT LED 19a and the AT LED 19b go from the lit state to the non-lit state once, and after the favorable zone is entered and the CZ4 state begins, the CZ·AT LED 19a and the AT LED 19b go back to the lit state. However, even if the favorable zone continues and the CZ4 state is controlled, the CZ·AT LED 19a and the AT LED 19b go from the lit state to the non-lit state once in the preparation state, and then remain in the non-lit state for at least one game. After becoming unlit, LED 19a during CZ·AT and LED 19b during AT will turn on again after the CZ4 state begins. Even if the advantageous period continues and the game is controlled to the CZ4 state, LED 19a during CZ·AT and LED 19b during AT will turn off temporarily, just as in the case where the advantageous period ends and the game is controlled to the CZ4 state. This makes it difficult to determine whether the advantageous period continued and the game was controlled to the CZ4 state, or whether the advantageous period ended and the game was controlled to the CZ4 state.

[0343] In particular, when the advantageous period continues, LED 19a during CZ·AT will continue to be lit when switching from one state in which LED 19a during CZ·AT is lit to the other state, such as when transitioning from CZ1 state to AT3 state, when transitioning from CZ3 state to AT3 state, when transitioning from CZ4 state to AT4 state, etc. However, when switching from AT4 state to CZ4 state in a situation in which the advantageous period continues, there is a preparation state in between, during which LED 19a during CZ·AT is temporarily turned off, making it difficult to determine whether the advantageous period continued and the state was controlled to CZ4 state, or whether the advantageous period ended and the state was controlled to CZ4 state.

[0344] In this embodiment, the main control unit 41 conducts a stock lottery to determine whether or not to grant the right to control back to the AT4 state when a stock lottery target role (a lottery role corresponding to FC5 to 7) is won in the AT4 state, and if the stock lottery is won, the right to win the AT is stocked, and the sub-control unit 91 notifies the player when the right to win the AT is stocked and notifies the player in an identifiable manner of the number of remaining rights to win the AT. If the right to the AT is stocked at the end of the AT4 state, the game is controlled again to the AT4 state from the next game without going through the preparation state or CZ4 state, and in a situation where it is confirmed that the AT4 state will continue, the AT4 state can be continued promptly without any unnecessary period of time.

[0345] In this embodiment, when the right to win the AT is stocked, the fact is notified, and the number of remaining rights to win the AT is also notified in an identifiable manner, but it is not necessary to notify all rights in an identifiable manner, and only some rights may be notified in an identifiable manner. In such a configuration, only when the right to win the AT is notified in an identifiable manner, if the right to win the AT is stocked at the end of the AT4 state, the game may be controlled to the AT4 state again from the next game without going through the preparation state or CZ4 state, and if the right to win the AT is stocked but not notified in an identifiable manner, the game may be controlled to the AT4 state by consuming the stock after going through the preparation state or CZ4 state, and by using such a configuration, it is possible to expect that the right to win the AT is stocked even if the AT4 state does not start immediately after the end of the AT4 state.

[0346] In this embodiment, the sub-control unit 91 has an acquired number counter value that counts the number of medals acquired during a series of ATs (a period during which the AT3 state and the AT4 state are continuous without a normal state), and executes an acquired number notification that notifies the number of medals acquired during a series of ATs based on the acquired number counter value in the AT3 performance during the AT3 state and the AT4 performance during the AT4 state. In addition, when the AT4 state ends and the advantageous zone ends and transitions to the normal zone, the acquired number counter value is carried over without being reset, and then, when the AT lottery is won during the advantageous zone transition or in the CZ4 state that is controlled first after the advantageous zone transition and the AT4 state is controlled, the acquired number notification is executed based on the acquired number counter value carried over and counted from the AT4 state before the advantageous zone ends, so that it is possible to make it appear that the AT4 state is occurring continuously even if the advantageous zone is interrupted.

[0347] In this embodiment, the number of won coins is notified in the AT3 performance during the AT3 state, and in the AT4 performance during the AT4 state, but the number of won coins may also be notified in the CZ3 performance during the CZ3 state, and in the CZ4 performance during the CZ4 state.

[0348] In addition, in this embodiment, when the AT4 state ends with the net increase in the number of coins in the advantageous zone being equal to or less than the upper limit number, and after the advantageous zone is ended, a new advantageous zone starts and the CZ4 state starts, the sub-control unit 91 executes a result notification effect at the end of the AT4 state and advantageous zone, and then executes a standby effect in the normal zone, as in the case where the advantageous zone continues, and when the CZ4 state starts, the standby effect is switched to a CZ4 introduction effect and then to a CZ4 effect (normal) or a CZ4 effect (ED), whereas the number of games is added, and the sub-control unit 91 is controlled to the ED state, and the net increase in the number of coins in the advantageous zone is increased. When the AT4 state ends after the number of sheets exceeds the upper limit, and the advantageous zone ends, a new advantageous zone starts and the CZ4 state starts. Unlike when the advantageous zone continues, the ED performance is executed when the ED state control starts, and at the end of the AT4 state and advantageous zone, in addition to the result notification, a result notification and advantageous zone end performance is executed to notify that the advantageous zone ends as a result of the net increase in the number of sheets exceeding the upper limit of the advantageous zone, and then a normal performance is executed in the normal zone, and when the CZ4 state starts and the AT lottery is won, a revival performance is executed and then the performance is switched to the CZ4 performance. In this way, when the net increase in the advantageous zone exceeds the upper limit and the advantageous zone ends, and a new advantageous zone starts, the performance mode is different from the performance mode when the advantageous zone ends without the net increase in the advantageous zone exceeding the upper limit, and the advantageous zone starts, so that the discomfort of the AT4 state continuing anew can be reduced.

[0349] As shown in FIG. 37, when the net increase in the number of sheets in the advantageous zone exceeds the upper limit number and the AT4 state ends, and after the advantageous zone ends, a new advantageous zone starts and the CZ4 state starts, and the AT lottery is won, at the end of the AT4 state and advantageous zone, the result notification and advantageous zone end performance is executed, and then, in the normal zone, the normal performance is executed, and in the CZ4 state after the transition to the advantageous zone, the normal performance is continued, and when the AT lottery is won in the CZ4 state and the AT4 state starts after the CZ4 state ends, the normal performance may be switched from the AT4 performance to the AT4 performance. With this configuration, when the net increase in the number of sheets in the advantageous zone exceeds the upper limit number and the advantageous zone ends, the relationship with the subsequent AT4 state becomes weak, so that the discomfort of the AT4 state continuing anew can be reduced even though the net increase in the number of sheets in the advantageous zone exceeds the upper limit number and the advantageous zone ends. Also, with this configuration, if the CZ4 state ends without winning the AT lottery after the transition to the advantageous zone, the normal performance may be continued as it is. Furthermore, in such a configuration, when the AT lottery is won during the transition to the favorable zone or in the CZ4 state after the transition to the favorable zone and the player is controlled to the AT4 state, it is preferable to reset the net increase in the number of coins counter value to 0 and not carry over the number of coins won in the AT4 state before the end of the favorable zone.By adopting such a configuration, when the net increase in the number of coins in the favorable zone exceeds the upper limit and the favorable zone ends, the connection with the subsequent AT4 state becomes even weaker, thereby further reducing the sense of discomfort caused by the AT4 state continuing even though the net increase in the number of coins in the favorable zone exceeds the upper limit and the favorable zone ends.

[0350] In this embodiment, after the AT4 state ends, the advantageous zone ends and the game moves to the normal zone, and when the game moves to the advantageous zone again, the game is controlled to the CZ4 state, which is likely to be controlled to the AT4 state. After the AT4 state ends, the advantageous zone ends and the game moves to the normal zone, and when the game moves to the advantageous zone again, the game is controlled to the CZ4 state. In this case, the presentation mode of the CZ4 state is selected based on the game history in the advantageous zone that has ended, so that even if the advantageous zone is interrupted, it can be made to appear as if the AT4 state and the subsequent CZ4 state are occurring continuously.

[0351] Furthermore, in this embodiment, the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and a transition occurs again to an advantageous zone is selected based on the history of the AT4 state in the ended advantageous zone, so that even if the advantageous zone ends, it is possible to make it appear as if the previous AT4 state and the subsequent CZ4 state are occurring continuously.

[0352] In this embodiment, the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and the game moves back to the advantageous zone is selected based on the history of the AT4 state in the ended advantageous zone. However, the same effect can be achieved as long as the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and the game moves back to the advantageous zone is selected based on at least the game history in the ended advantageous zone. For example, the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and the game moves back to the advantageous zone may be selected based on the history of the number of medals won (net increase) in the ended advantageous zone, the number of games continued in the advantageous zone, etc.

[0353] In addition, in this embodiment, the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and transitions to another advantageous zone is selected based on the number of consecutive ATs in the ended advantageous zone (the number of times that the AT3 state and the AT4 state are consecutive without a normal state in between), but it may also be selected based on the history of the AT state in the ended advantageous zone, such as the number of consecutive AT4 states in the ended advantageous zone (the number of times that the AT4 state is consecutive without a normal state in between), the number of medals increased in a series of AT periods (periods in which the AT3 state and the AT4 state are consecutive without a normal state in between), the number of games controlled to the AT4 state without a normal state in between, the number of games controlled to the AT3 state and the AT4 state without a normal state in between, the number of times the number of games was added in the AT4 state, the number of times the number of games was added in the AT3 state and the AT4 state, etc.

[0354] In this embodiment, the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and the player transitions to another advantageous zone is such that the CZ4 presentation (ED) is selected only if the number of consecutive ATs (the number of consecutive AT3 and AT4 states without a normal state in between) in the advantageous zone that has ended is 20 or more, i.e., if the AT state continues for a long period of time.By executing the CZ4 presentation (ED) in the CZ4 state, the player can recognize that the player has been controlled to the AT state for a long period of time.

[0355] In this embodiment, the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and transitions to another advantageous zone is configured so that the CZ4 presentation (ED) is selected only if the number of consecutive ATs in the ended advantageous zone is 20 or more. However, even if the CZ4 presentation (ED) is selected only when the AT state continues for a long period of time, such as when the number of consecutive AT4 states is a specified number or more, when the number of games controlled to AT4 in the ended advantageous zone is a specified number or more, or when the number of games controlled to the AT3 state or AT4 state is a specified number or more, the CZ4 presentation (ED) is executed in the CZ4 state, allowing the player to recognize that they are being controlled to the AT state for a long period of time.

[0356] In addition, in this embodiment, with regard to the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and transitions to another advantageous zone, a specific presentation mode (CZ4 presentation (ED)) is selected only when the period during which the AT state continues in the ended advantageous zone is a specific period (20 times) or more; however, the configuration may also be such that when the period during which the AT state continues in the ended advantageous zone is a specific period (20 times) or more, a specific presentation mode is more likely to be selected than when the period during which the AT state continues in the ended advantageous zone is less than a specific period (20 times); even with such a configuration, by executing a CZ4 presentation of a specific presentation mode in the CZ4 state, it is possible to recognize that the player is being controlled in the AT state for a long period of time.

[0357] In this embodiment, the presentation mode of the CZ4 state controlled when the advantageous zone is ended and transitioned to the advantageous zone again is selected based on the history of the AT state in the ended advantageous zone and the type of advantageous zone transition role that triggered transition to the advantageous zone again. Specifically, when the advantageous zone transition role is a role belonging to FC0 or FC1 that may not win the AT lottery, the CZ4 presentation (ED) may be selected, whereas when it is a role belonging to FC3 to FC7 that always wins the AT lottery, the CZ4 presentation (ED) is not selected, and the CZ4 presentation (normal) is always selected. In this way, when the advantageous zone is ended and transitioned to the normal zone, and the advantageous zone is transitioned to again, the presentation mode of the CZ4 state is selected based on the history of the AT state in the ended advantageous zone and the type of advantageous zone transition role that triggered transition to the advantageous zone again, so that the presentation mode according to the trigger of transition to the advantageous zone can be selected.

[0358] In this embodiment, the presentation mode of the CZ4 state, which is controlled when the favorable zone ends and a transition is made to another favorable zone, is selected based on the history of the AT state in the favorable zone where the zone has ended, and whether or not the AT4 state will be controlled after the CZ4 state ends, so that attention can be drawn to the presentation mode of the CZ4 state.

[0359] In addition, in this embodiment, an AT lottery is conducted to determine whether or not to control to an AT4 state after the CZ4 state depending on the favorable zone transition role that ended the favorable zone and triggered a transition to the favorable zone again, and an AT lottery is conducted to determine whether or not to control to an AT4 state after the CZ4 state depending on the result of an internal lottery in the first game in the CZ4 state.After the AT4 state ends, the favorable zone ends and transitions to the normal zone, and when the favorable zone is transitioned to again, the CZ4 state is controlled. In this case, the presentation mode of the CZ4 state is selected based on the results of both the AT lottery at the transition to the favorable zone and the AT lottery in the first game in the CZ4 state, so that the results of both the AT lottery at the transition to the favorable zone and the AT lottery in the first game in the CZ4 state can be reflected in the presentation mode of the CZ4 state.

[0360] Furthermore, in this embodiment, with regard to the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and a transition is made to the advantageous zone again, the CZ4 presentation (ED) is selected only if the AT4 state is not controlled after the end of the CZ4 state, and if the AT4 state is controlled, the CZ4 presentation (normal) is selected, so that it is possible to make it appear as if the AT4 state is occurring continuously even if the advantageous zone is interrupted.

[0361] In this embodiment, the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and the game moves back to the advantageous zone is configured so that the CZ4 presentation (ED) is selected only if the game is not controlled to the AT4 state after the end of the CZ4 state; however, the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and the game moves back to the advantageous zone may be configured so that if the game is not controlled to the AT4 state after the end of the CZ4 state, a specific presentation mode is more likely to be selected than if the game is controlled to the AT4 state after the end of the CZ4 state. In this configuration, if the game is not controlled to the AT4 state after the CZ4 state, a specific presentation mode is more likely to be selected in the CZ4 state, whereas if the game is controlled to the AT4 state, a specific presentation mode is less likely to be selected in the CZ4 state, making it appear as if the AT4 state is occurring continuously.

[0362] [Effect 2] In this embodiment, after the AT4 state ends, the advantageous zone ends and the game moves to the normal zone, and when the game moves to the advantageous zone again, the game is controlled to the CZ4 state, which is likely to be controlled to the AT4 state. After the AT4 state ends, the advantageous zone ends and the game moves to the normal zone, and when the game moves to the advantageous zone again, the game is controlled to the CZ4 state. In this case, the presentation mode of the CZ4 state is selected based on the game history in the advantageous zone that has ended, so that even if the advantageous zone is interrupted, it can be made to appear as if the AT4 state and the subsequent CZ4 state are occurring continuously.

[0363] Furthermore, in this embodiment, the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and a transition occurs again to an advantageous zone is selected based on the history of the AT4 state in the ended advantageous zone, so that even if the advantageous zone ends, it is possible to make it appear as if the previous AT4 state and the subsequent CZ4 state are occurring continuously.

[0364] In this embodiment, the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and the player transitions to another advantageous zone is such that the CZ4 presentation (ED) is selected only if the number of consecutive ATs (the number of consecutive AT3 and AT4 states without a normal state in between) in the advantageous zone that has ended is 20 or more, i.e., if the AT state continues for a long period of time.By executing the CZ4 presentation (ED) in the CZ4 state, the player can recognize that the player has been controlled to the AT state for a long period of time.

[0365] In this embodiment, after the advantageous state ends, the advantageous zone ends and the game transitions to the normal zone, and when the game transitions to the advantageous zone again, the CZ4 state presentation mode is selected based on the AT state history in the advantageous zone that ended and the type of advantageous zone transition role that triggered the transition to the advantageous zone again, so that the presentation mode can be selected according to the trigger for transitioning to the advantageous zone.

[0366] In this embodiment, the presentation mode of the CZ4 state, which is controlled when the favorable zone ends and a transition is made to another favorable zone, is selected based on the history of the AT state in the favorable zone where the zone has ended, and whether or not the AT4 state will be controlled after the CZ4 state ends, so that attention can be drawn to the presentation mode of the CZ4 state.

[0367] In addition, in this embodiment, an AT lottery is conducted to determine whether or not to control to an AT4 state after the CZ4 state depending on the favorable zone transition role that ended the favorable zone and triggered a transition to the favorable zone again, and an AT lottery is conducted to determine whether or not to control to an AT4 state after the CZ4 state depending on the result of an internal lottery in the first game in the CZ4 state.After the AT4 state ends, the favorable zone ends and transitions to the normal zone, and when the favorable zone is transitioned to again, the CZ4 state is controlled. In this case, the presentation mode of the CZ4 state is selected based on the results of both the AT lottery at the transition to the favorable zone and the AT lottery in the first game in the CZ4 state, so that the results of both the AT lottery at the transition to the favorable zone and the AT lottery in the first game in the CZ4 state can be reflected in the presentation mode of the CZ4 state.

[0368] Furthermore, in this embodiment, with regard to the presentation mode of the CZ4 state that is controlled when the advantageous zone ends and a transition is made to the advantageous zone again, the CZ4 presentation (ED) is selected only if the AT4 state is not controlled after the end of the CZ4 state, and if the AT4 state is controlled, the CZ4 presentation (normal) is selected, so that it is possible to make it appear as if the AT4 state is occurring continuously even if the advantageous zone is interrupted.

[0369] [Effect 3] In this embodiment, after the AT4 state ends, the favorable zone is ended and the normal zone is entered, and when the favorable zone is entered again, the CZ4 state is controlled; after the AT4 state ends, the favorable zone is likely to be controlled to the AT4 state while it continues; and after the AT3 state ends, the favorable zone is likely to be controlled to the AT3 state while it continues. When the favorable zone is continued and the CZ4 state is controlled, the CZ4 state is controlled through a preparation state. When the favorable zone is continued and the favorable zone is ended and the CZ4 state is controlled when it transitions to the favorable zone again after the AT4 state ends, a waiting period is always generated after the AT4 state ends and before the CZ4 state starts. However, even when the favorable zone is continued and the CZ4 state is controlled, the CZ4 state does not start immediately, but is controlled to the CZ4 state through a preparation state for a predetermined period, so that it is difficult to determine whether the favorable zone is continued and the favorable zone is ended and then the CZ4 state is controlled.

[0370] On the other hand, if the advantageous zone continues after the AT3 state ends and the player is controlled to the CZ3 state, the player will be controlled to the CZ3 state without going through the preparation state, so if the advantageous zone continues after the AT3 state ends and the player is controlled to the CZ3 state, the player can quickly transition to the CZ3 state after the AT3 state ends.

[0371] The CZ4 state in this embodiment is a state in which the probability of winning the AT lottery is set higher than in the CZ3 state, and being controlled to the preparation state can give the player the expectation of being controlled to the AT4 state.

[0372] In this embodiment, the AT states include an AT3 state and an AT4 state in which it is expected that more medals will be won than in the AT3 state. When controlled from the CZ4 state to the AT state, it is controlled to the AT4 state, and when controlled from the CZ3 state to the AT state, it is controlled to the AT3 state. Therefore, by being controlled to the preparation state, it can be expected that it will be controlled to the more advantageous AT4 state.

[0373] In this embodiment, an AT lottery is conducted when transitioning to a favorable zone, and if the AT lottery is won when transitioning to a favorable zone, the system is controlled to the AT4 state. This prevents the system from being controlled to an unintended type of AT state when transitioning to a favorable zone in the process of being controlled to the CZ4 state after the AT4 state ends and the system transitions to the favorable zone again after the favorable zone ends.

[0374] In this embodiment, the number of games controlled to the CZ4 state is less than the number of games controlled to the CZ3 state, so even if the game is controlled to the preparation state after the end of the AT4 state, the period from whence the game passes through the CZ4 state until when it is controlled to the AT4 state is not redundant.

[0375] In this embodiment, when a favorable zone transition role is won in the normal zone, the system transitions to the favorable zone, and even in the preparation state in which the system is controlled to the CZ4 state while the favorable zone continues, the preparation state is terminated and the system is controlled to the CZ4 state when a favorable zone transition role is won. If the system is controlled to the CZ4 state while the favorable zone continues, the system will be controlled to the CZ4 state at the same trigger as when the system is controlled to the CZ4 state after the favorable zone ends, making it difficult to determine whether the system was controlled to the CZ4 state while the favorable zone continued, or whether the system was controlled to the CZ4 state after the favorable zone ended.

[0376] In this embodiment, no control related to the AT is performed in the normal area, and even if the game is played in a stopping operation sequence in which a reel other than the left reel is the first stop, no penalty is given in relation to the AT and no warning notification is issued. However, even if the game is played in a stopping operation sequence in which a reel other than the left reel is the first stop in the preparation state, unlike the normal state, premonition state, CZ1 state, CZ3 state, and CZ4 state, no penalty is given in relation to the AT, and as with the normal area, there is no change in the advantageous degree related to the AT, and no warning notification is issued for the AT, making it difficult to determine whether the advantageous area continues and the game is controlled to the CZ4 state, or whether the advantageous area ends and the game is controlled to the CZ4 state.

[0377] In this embodiment, when the AT4 state ends and the favorable period ends, the CZ·AT signal and the AT signal turn off once, and after the favorable period has started and the CZ4 state has begun, the CZ·AT signal and the AT signal turn on again. However, even when the favorable period continues and the CZ4 state is controlled, the CZ·AT signal and the AT signal turn off once in the preparation state, and then turn off for at least one game, and after the CZ4 state begins, the CZ·AT signal and the AT signal turn on again. Even when the favorable period continues and the CZ4 state is controlled, the CZ·AT signal and the AT signal turn off once, just as when the favorable period ends and the CZ4 state is controlled, so that it is difficult to determine whether the favorable period continues and the CZ4 state is controlled, or whether the favorable period ends and the CZ4 state is controlled.

[0378] In this embodiment, when the AT4 state ends and the favorable zone ends, the CZ·AT LED 19a and the AT LED 19b go from the lit state to the non-lit state once, and after the favorable zone is entered and the CZ4 state begins, the CZ·AT LED 19a and the AT LED 19b go back to the lit state. However, even if the favorable zone continues and the CZ4 state is controlled, the CZ·AT LED 19a and the AT LED 19b go from the lit state to the non-lit state once in the preparation state, and then remain in the non-lit state for at least one game. After becoming unlit, LED 19a during CZ·AT and LED 19b during AT will turn on again after the CZ4 state begins. Even if the advantageous period continues and the game is controlled to the CZ4 state, LED 19a during CZ·AT and LED 19b during AT will turn off temporarily, just as in the case where the advantageous period ends and the game is controlled to the CZ4 state. This makes it difficult to determine whether the advantageous period continued and the game was controlled to the CZ4 state, or whether the advantageous period ended and the game was controlled to the CZ4 state.

[0379] In this embodiment, it is determined whether the remaining net increase in the number of coins (maximum number of coins - net increase in the advantageous zone) at the end of the AT4 state is less than a specific number (200 in this embodiment), and if the remaining net increase in the number of coins is less than the specific number, the advantageous zone is ended and the game zone is transitioned to the normal zone. This prevents the net increase in the number of coins in the advantageous zone exceeding the maximum number of coins during the AT4 state, thereby meeting the conditions for ending the advantageous zone and suddenly ending the AT4 state, or restricting the addition of the remaining number of games through an additional lottery or the granting of the right to the AT4 state through a stock lottery so as not to reach the maximum number of coins.

[0380] In this embodiment, the main control unit 41 conducts a stock lottery to determine whether or not to grant the right to control back to the AT4 state when a stock lottery target role (a lottery role corresponding to FC5 to 7) is won in the AT4 state, and if the stock lottery is won, the right to win the AT is stocked, and the sub-control unit 91 notifies the player when the right to win the AT is stocked and notifies the player in an identifiable manner of the number of remaining rights to win the AT. If the right to the AT is stocked at the end of the AT4 state, the game is controlled again to the AT4 state from the next game without going through the preparation state or CZ4 state, and in a situation where it is confirmed that the AT4 state will continue, the AT4 state can be continued promptly without any unnecessary period of time.

[0381] Although the second embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to this second embodiment, and it goes without saying that the present invention includes modifications and additions that do not deviate from the spirit of the present invention.
