When the advantageous state (AT2 state) ends, the specific light-emitting units (LED 19a during CZ / AT, LED 19b during AT) are temporarily set to a non-light-emitting state (non-illuminated state), and after the game transitions to the high probability state (CZ2 state), they are set to an illuminating state (illuminated state). When controlling to the high probability state (CZ2 state) while continuing the advantageous zone, the specific light emitting part (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 (AT2 state) ends, and after being set to a non-light emitting state (non-illuminated state) for at least one game, it is set to a light emitting state (illuminated state) after transitioning to the high probability state (CZ2 state). It is characterized by the following. According to this feature, even when the advantageous zone continues and is controlled to a high probability state, the specific light-emitting section temporarily goes into a non-light-emitting state, just as when the advantageous zone ends and is controlled to a high probability state, making it difficult to determine whether the advantageous zone continues and is controlled to a high probability state, or whether the advantageous zone ends and is controlled to a high probability state.

[0025] The slot machine of aspect 3-6 is the slot machine according to any one of aspects 3-1 to 3-5, The termination condition of the advantageous zone 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 zone exceeds an upper limit amount (upper limit number of coins), When the second advantageous state (AT2 state) ends, if the difference (remaining net increase) between the amount of gaming value (net increase) acquired by the player in the advantageous period 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 preventing the addition from being limited so as not to reach the upper limit amount.

[0031] Although the CZ·AT LED 19a and the AT LED 19b are provided separately in this embodiment, a single LED that lights up to indicate that the CZ·AT signal is on or that the AT signal is on may also serve as both. In this case, the LED is kept unlit when both the CZ·AT signal and the AT signal are off, and is lit when at least one of the CZ·AT signal or the AT signal turns on. Thereafter, the LED is kept unlit when both the CZ·AT signal and the AT signal turn off. With this configuration, the LED is always lit when either the CZ·AT signal or the AT signal is on, making it possible to confirm that either signal is being output.

[0032] Inside the MAXBET switch 6, there is provided a BET switch valid LED 21 (see Figure 3) which lights up to indicate that the operation of setting the bet number by operating the MAXBET switch 6 is valid, and inside the stop switches 8L, 8C, 8R there are provided left, center, 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.

[0033] 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 elements, and is provided so that its display area is located in front of the reels 2L, 2C, and 2R of the front door 1b (on the player's side). The reels 2L, 2C, and 2R on the back side of the liquid crystal display 51 can be seen from the player's side through the transparent area of ​​the display area of ​​the liquid crystal display 51 that corresponds to the see-through window 3 and through the see-through window 3.

[0034] On the inside of the front door 1b of the slot machine 1, there are provided a reset switch 23 that detects a reset operation to release an error state from outside the slot machine 1 by operating a predetermined key, a setting value display 24 that displays the setting value at that time while the setting value is being changed or checked, a door open detection switch 25 that detects the open state of the front door 1b, a flow path switching solenoid 30 that selectively switches the flow path of medals inserted from the medal insertion port 4 to either the hopper tank side or the medal payout outlet 9 side, which are described below and are located inside the slot machine 1, and a medal selector 29 having inserted medal sensors 31a to 31c that detect medals inserted from the medal insertion port 4 and flowing down to the hopper tank side.

[0035] Also provided inside the slot machine 1 are a reel unit 34 for rotating or 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 the medal payout outlet 9 in response to a control signal from the main control unit 41.

[0036] 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 canceling an error state under normal circumstances and 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 / off.

[0037] As shown in Figure 3, the slot machine 1 is provided with a game control board 40 and a presentation control board 90, and the game (game) is controlled by the game control board 40, and the presentation control board 90 controls the presentation according to the game status.

[0038] 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, reel sensor (not shown) of reel unit 34, payout sensor and full sensor (not shown) of hopper unit 35, setting key switch 37, and reset / setting switch 38, and detection signals from these connected switches etc. are input.

[0039] In addition, the game control board 40 is connected to the aforementioned credit indicator 11, game auxiliary indicator 12, 1 to 3 BET LEDs 14 to 16, start valid LED 18, CZ / AT in progress LED 19a, AT in progress LED 19b, replay in progress LED 20, BET switch valid LED 21, left, center, right stop valid LEDs 22L, 22C, 22R, setting value indicator 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 described below which is mounted on the game control board 40.

[0040] 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 that stores programs and the like, and a RAM 41c that temporarily stores work data.

[0041] Furthermore, 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 commands are never transmitted from the sub-control unit 91 to the main control unit 41.

[0042] In addition, the main control unit 41 outputs a CZ-AT signal, which can identify that the machine is being 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 being controlled to the AT state described below, to external hall equipment such as a call lamp via an external output board (not shown).

[0043] The performance control board 90 is connected to the aforementioned performance switch 56, and its detection signal is input thereto. 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 its light emission mode 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.

[0044] The slot machine 1 of this embodiment is configured to change the medal payout rate according to a setting value. Specifically, the medal payout rate is changed by using the winning probability according to the setting value in a lottery that affects the player's advantage, such as an internal lottery or an AT lottery. The setting value has six levels, 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 setting value, the player has the highest advantage, and the advantage gradually decreases as the value decreases in the order of 5, 4, 3, 2, and 1.

[0045] To change the setting value, the setting key switch 37 must be turned ON before the power switch 39 of the slot machine 1 is turned ON. When the setting key switch 37 is turned ON and the power is turned ON, the setting value read from the RAM 41c is displayed on the setting value display 24 as a display value, and the slot machine transitions to a setting change state in which the setting value can be changed by operating the reset / set switch 38. In the setting change state, when the reset / set switch 38 is operated, the display value displayed on the setting value display 24 is updated by 1 (when the reset / set switch 38 is operated again from setting value 6, the display value returns to setting value 1). When the start switch 7 is operated, the display value is confirmed as the setting value. When the setting key switch 37 is turned OFF, the confirmed display value (setting value) is stored in the RAM 41c of the main control unit 41, and the slot machine transitions to a state in which game progress is possible. In addition, the main control unit 41 initializes the game-related data stored in the RAM 41c in response to the change of the setting value.

[0046] 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 operating a predetermined key, is opened. Therefore, only staff members of the gaming establishment where the slot machine 1 is installed who possess a predetermined key can operate them. In particular, the setting key switch 37 requires an additional key operation, so only staff members of the gaming establishment who possess a key for operating the setting key switch 37 can operate them. The reset switch 23 does not require opening the front door 1b, but requires key operation using a predetermined key, so only staff members who possess the predetermined key can operate it. The reset / setting switch 38 also functions as a reset switch for resetting an error state under normal circumstances.

[0047] To play a game on the slot machine 1 of this embodiment, first, medals are inserted into the medal insertion slot 4, or the MAXBET switch 6 is operated to set the bet amount using credits. Once the specified number of bets determined according to the game status is set, a predetermined pay line LN (see FIG. 1; in this embodiment, it is set across the symbols arranged in a curved line in the middle of reels 2L and 2C and the top of reel 2R) becomes valid, and operation of the start switch 7 becomes valid, i.e., the game can be started. Note that if medals are inserted in excess of the maximum number of medals corresponding to the game status, the amount is added to the credits. Also, although only one pay line is used in this embodiment, multiple pay lines may be used.

[0048] 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 pay line LN, inactive lines LM1 to LM5 are set up separately from the pay line LN. A win is not determined by the combination of symbols that line up on these inactive lines LM1 to LM5, but rather, when a combination of symbols that constitute a win has been lined up on the pay line LN, a combination of symbols that suggests a win (for example, bell a-bell a-bell a) that is indicative of a win has been 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 pay line LN.

[0049] When the start switch 7 is operated in a state where the game is ready to start, 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 is 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.

[0050] In the stop control, control is performed to stop the rotation of reels 2L, 2C, and 2R corresponding to the operation within the maximum stop delay time (190 ms (milliseconds) in this embodiment) from when each stop switch is operated, and up to four frames of symbols can be pulled 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 stop switches 8L, 8C, and 8R are operated and the symbols four frames ahead, a total of five frames (pulling-in range), and to lead it to reels 2L, 2C, and 2R.

[0051] As a result, in the stop control, when the corresponding stop switches 8L, 8C, and 8R for each reel 2L, 2C, and 2R are operated to stop rotation, if the pattern that constitutes the winning combination that has been won in the internal lottery described below is within a retraction range of 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 that constitutes the winning combination that has been won in the internal lottery is not within the retraction range, the pattern that does not constitute any winning combination is retracted onto the winning line LN, and the rotation of the reel for which the stop switch is operated is stopped, so that the patterns that constitute the winning combination that has not been won in the internal lottery do not stop on the winning line LN.

[0052] In addition, in the stop control, when the winning of a special role (in this embodiment, BB) accompanied by a transition of the game state is carried over, a small role accompanied by the awarding of medals is won in an internal lottery, and in a situation where the special role and the small role are won at the same time, the constituent symbols of the winning small role are controlled to be drawn preferentially to the winning line LN within the aforementioned 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 where a special role and a small role are won at the same time, it is difficult to make the winning special role win.

[0053] Furthermore, in the stop control, if a special role (BB in this embodiment) is carried over, and a replay role that grants a replay is won in an internal lottery, and the special role and the replay role are simultaneously won, the constituent symbols of the winning replay role are given priority and drawn into the winning line LN. The symbols that constitute the replay role on each reel 2L, 2C, and 2R are arranged within a predetermined draw range, and when a replay role is won, the constituent symbols of the replay role are always drawn into the winning line LN. For this reason, in a game in which a special role and a replay role are simultaneously won, the winning special role cannot be drawn into a winning position.

[0054] A game ends when all reels 2L, 2C, and 2R are stopped. When a predetermined winning combination of symbols stops on the winning line LN as a result of displaying on each reel 2L, 2C, and 2R, a win occurs. Control according to the win is performed. When a minor combination is won, a predetermined number of medals according to the type of combination is awarded to the player and added to the player's credits. Furthermore, when the credit limit (50 in this embodiment) is reached, medals are paid out directly from the medal payout opening 9 (see FIG. 1). Furthermore, when a replay combination is won, a replay is awarded, allowing the player to play without inserting medals. Furthermore, when a special combination is won, the game state is transitioned to another game state.

[0055] In this embodiment, a game starts when operation of the start switch 7 is detected while operation of the start switch 7 is enabled, and ends when all the reels have stopped. Also, one unit of control for executing a game (game control) starts when all controls associated with the end of the previous game have been completed, and ends when all controls associated with the end of the current game have been completed.

[0056] 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 status and include a minor combination that results in the payout of medals, a replay combination that allows the player to start the next game without having to set a bet amount, and a special combination that results in a transition to a new game status. Hereinafter, the minor combination and the replay combination will be collectively referred to as a general combination. For each combination determined according to the game status to win, an internal lottery must be won and a winning flag for that combination must be set. The internal lottery is performed 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 displayed (specifically, when the operation of the start switch 7 is detected with the specified bet amount set).

[0057] Among the winning flags for each role, the winning flags for the small role and the replay role are valid only 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 allowed by the flag is achieved and is invalid in the game in which the combination of roles allowed by the flag is achieved. In other words, once a winning flag for a special role is won, even if the combination of roles allowed by the flag is not achieved, the winning flag is not invalidated and is carried over to the next game.

[0058] Furthermore, in the internal lottery, when a stop operation is performed in a predetermined operation mode (for example, a push order or operation timing), a small role or a replay role (hereinafter sometimes referred to as a navigation target role) that is more advantageous than when the stop operation is performed in another operation mode can be won. Navigation target roles include, for example, roles that result in a stop pattern that is more advantageous when the stop operation is performed in a predetermined operation mode than when the stop operation is performed in another operation mode, and roles that result in a higher probability of a stop pattern that is more advantageous when the stop operation is performed in a predetermined operation mode than when the stop operation is performed in another operation mode. Furthermore, advantageous stop patterns include not only stop patterns that result in the awarding of medals, but also stop patterns that result in a transition to an advantageous game state and stop patterns that avoid a transition to an unfavorable game state.

[0059] The main control unit 41 can control the system to an assist time (AT) state, which is a notification period during which a navigation notification can be executed. The navigation notification notifies the player of navigation information, which can identify the operation mode of the stop switches 8L, 8C, and 8R that is advantageous to the player, by the lighting mode of the gaming assist display 12, based on the results of an internal lottery. The main control unit 41 begins control of the AT state when the player is granted the right to be controlled to the AT state. Then, when the system is controlled to the AT state, if a navigation target role is won, the navigation notification is executed to notify the player of the operation mode of the stop switches 8L, 8C, and 8R that is advantageous to the player (e.g., the push order, operation timing, etc.) using the gaming assist display 12, and a command that can identify the operation mode that is advantageous to the player is sent to the sub-control unit 91, which executes a navigation effect that notifies the operation mode using the LCD display 51, etc. By operating the stop switches 8L, 8C, and 8R using the operation mode indicated by the navigation notification and the navigation effect, the player can reliably win the navigation target role that was won in the internal lottery.

[0060] In this embodiment, the main control unit 41 is provided 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.

[0061] [About game status] The main control unit 41 can control the gaming state to any one of non-internal, internal, and special states.

[0062] During the non-internal state, the winning of the special role (BB) is not carried over. When the slot machine 1 is in its factory default state or when the game-related data stored in the RAM 41c is initialized due to a setting change, the slot machine 1 is first controlled to be in the non-internal state. Furthermore, when the special state ends, the slot machine 1 is controlled to be in the non-internal state. Furthermore, the non-internal state ends when a special role (BB) is won in an internal lottery in a game during the non-internal state, the special role is lost, and the slot machine 1 transitions to the internal state. Furthermore, the non-internal state ends when a special role (BB) is won in a game during which the special role (BB) is won in an internal lottery, and the slot machine 1 transitions to the special state.

[0063] Furthermore, during non-internal periods, if the stop switches 8L, 8C, and 8R are operated in an operation manner that is advantageous to the player in a game during a predetermined period, the medal payout rate per game during that period will exceed 100%, whereas if the stop switches 8L, 8C, and 8R are not operated in an operation manner that is advantageous to the player, the medal payout rate per game during that period will not exceed 100%. During non-internal periods, if an operation manner that is advantageous to the player is not notified, the medal payout rate per game will not exceed 100%.

[0064] During the internal draw, the winning of the special role (BB) is carried over. It starts when the special role (BB) is won in the internal draw during the non-internal draw.

[0065] Inside, when stop switches 8L, 8C, and 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%, while when stop switches 8L, 8C, and 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%, while during periods when an operation manner advantageous to the player is not notified, the medal payout rate per game does not exceed 100%.

[0066] The special state is a game state controlled by the winning of a special role (BB), and starts when the special role (BB) is won during a non-internal state, and ends when a predetermined termination 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 transitions to a non-internal state.

[0067] In the slot machine 1 of this embodiment, when the special role (BB) is won with a predetermined probability (for example, approximately 1 / 4.2) while not in the internal state, the state transitions to the internal state, and while 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 if the slot machine is controlled to the AT state, the medal payout rate per game exceeds 100%.

[0068] 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 alignment of the small role, and furthermore, for all small roles that are subject to internal lottery, the pull-in range of the constituent symbols of the special role (BB) and the pull-in range of the constituent symbols of the small role overlap, and no matter which small role is won, the constituent symbols of the winning small role will stop on the winning line LN. Also, 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 internally, the special role (BB) will not win.

[0069] In addition, since one of the small roles or one of the replay roles will always be won during the internal state, once the state has been shifted to the internal state, the special role (BB) will not be won, and after the shift to the internal state, the internal state will be maintained.

[0070] For this reason, in the slot machine 1 of this embodiment, since the majority of play is controlled internally, it is assumed that the machine is controlled internally, and the medal payout rate according 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 machine to AT internally, specifically, the probability of winning the internal lottery described below, the probability of transitioning to the AT state, etc.

[0071] In addition, the main control unit 41 can control the AT that notifies the user of the operation mode (correct pressing order) of the stop switches 8L, 8C, and 8R that is advantageous through a navigation notification while the winning of the special role (BB) is carried over, and is designed to ensure an appropriate medal payout rate during that period.

[0072] [Regarding roles eligible for internal lottery] As shown in FIG. 4, in this embodiment, there are normal replays that allow the winning of normal replays accompanied by the awarding of replays, rare replays that allow the winning of rare replays accompanied by the awarding of replays, 12 types of push order roles that allow the winning of main small roles accompanied by the awarding of 12 medals and sub small roles accompanied by the awarding of 1 medal, rare small role A that allows the winning of rare small role A accompanied by the awarding of 1 medal, rare small role B that allows the winning of rare small role B accompanied by the awarding of 3 medals, rare small role C that allows the winning of rare small role C accompanied by the awarding of 3 medals, and rare small role B that allows the winning of rare small role C accompanied by the awarding of 6 medals. The following may be subject to internal lottery: rare small feature D, which allows the winning of rare small feature D accompanied by the award of one medal; 1 small feature, which allows the winning of 1 small feature accompanied by the award of one medal; BB, which allows the winning of BB accompanied by a transition to a special state; BB + rare small feature A, which allows the winning of both BB and rare small feature A; BB + rare small feature B, which allows the winning of both BB and rare small feature B; BB + rare small feature C, which allows the winning of both BB and rare small feature C; BB + rare small feature D, which allows the winning of both BB and rare small feature D; and BB + 1 small feature, which allows the winning of both BB and 1 small feature. During non-internal play, the internal lottery is for regular replays, rare replays, 16 types of push sequence combinations, BB + rare minor combination A, BB + rare minor combination B, BB + rare minor combination C, BB + rare minor combination D, BB + 1-piece minor combination, and BB. During non-internal play, the internal lottery is set to have a winning probability of approximately 1 / 7.54 for a regular replay, approximately 1 / 228 for a rare replay, approximately 1 / 1.59 for a push sequence combination (each with a winning probability of approximately 1 / 12.7), 1 / 8192 for a BB + rare minor combination A, approximately 1 / 199 for a BB + rare minor combination B, approximately 1 / 60 for a BB + rare minor combination C, approximately 1 / 33 for a BB + rare minor combination D, approximately 1 / 5.46 for a BB + 1-piece minor combination, and 1 / 16384 for a BB.

[0073] Additionally, during the internal lottery, the regular replay, rare replay, 16 types of push sequence roles, rare minor roles A, rare minor roles B, rare minor roles C, rare minor roles D, and single-coin minor roles are subject to the internal lottery, while roles including special roles are not subject to the internal lottery. In the internal lottery, the winning probability of a regular replay is approximately 1 / 7.53, the winning probability of a rare replay is approximately 1 / 228, the winning probability of a push sequence role is approximately 1 / 1.59 (each winning probability is approximately 1 / 12.7), the winning probability of a rare minor role A is 1 / 8192, the winning probability of a rare minor role B is approximately 1 / 199, the winning probability of a rare minor role C is approximately 1 / 60, the winning probability of a rare minor role D is approximately 1 / 33, and the winning probability of a single-coin minor role is approximately 1 / 5.46.

[0074] As mentioned 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 by performing the stop operation 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 stop operation timing, while by performing the stop operation 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 stop operation timing, or the sub small role is lost and no prize is awarded. In other words, it is a minor role in which the expected value of the number of medals awarded changes depending on 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 announced.

[0075] 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 for the push order minor win. Playing with a stop operation sequence in which the center reel or the right reel is the first stop increases the medal award rate. However, in the normal state, premonition state, CZ1 state, and CZ2 state described below, a penalty is imposed in connection with the transition to the AT state, which is disadvantageous. As a result, the medal award rate taking into account the transition to the AT state is lower than when playing with a stop operation sequence in which the left reel is the first stop. Specifically, if a stop operation is performed with a stop operation sequence in which a reel other than the left reel is the first stop in the normal state and premonition state described below, the number of games completed described below is not updated, and in the CZ1 state and CZ2 state described below, the AT lottery is not performed. For this reason, in the normal state, premonition state, CZ1 state, and CZ2 state described below, playing with a stop operation sequence in which the left reel is the first stop is encouraged.

[0076] In addition, winning numbers from 1 to 29 are assigned to normal replay, rare replay, 16 types of push orders, rare minor role A, rare minor role B, rare minor role C, rare minor role D, single-coin minor role, BB+rare minor role A, BB+rare minor role B, BB+rare minor role C, BB+rare minor role D, BB+1-coin minor role, and BB, respectively, and the winning numbers of the winning roles obtained by the internal lottery are set in RAM 41c. Winning numbers of values ​​1 or less are assigned to roles that do not transition to the advantageous zone (described later), and winning numbers of 2 or more are assigned to advantageous zone transition roles that transition to the advantageous zone. Therefore, the main control unit 41 determines whether an advantageous zone transition role has been won in the normal zone by determining whether the winning number is 2 or greater, rather than by identifying individual winning numbers. If the winning number is 2 or greater, it determines that the advantageous zone transition role has been won.

[0077] In addition, a flag category (FC) is assigned to each winning combination in the internal lottery, and the flag category (FC) of the winning combination in the internal lottery is set in RAM 41c. The flag category (FC) is assigned a common value to combinations with common attributes, such as multiple types of push-order combinations, multiple combinations with similar winning probabilities, and combinations resulting in a common combination. Therefore, when determining the probability of a winning combination in performing an AT lottery (to be described later), the main control unit 41 determines the probability of a winning combination based on the value of the flag category (FC) assigned to the winning combination, rather than determining the probability of a winning combination based on each winning number. This eliminates the need to determine the probability for each individual winning number. By determining the probability for each flag category (FC), which is smaller than the number of winning numbers, it becomes possible to determine the probability based on the attributes of the winning combination.

[0078] [About navigation announcements 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.

[0079] During a predetermined game in which processing related to navigation notification is performed (from when the reels start spinning to when all reels stop spinning), the main control unit 41 can perform navigation notification to notify the player of a stop pattern that is advantageous to the player in accordance with the navigation target role by displaying a navigation display corresponding to the navigation target role that has been won in an internal lottery on the game auxiliary display 12. Furthermore, the main control unit 41 can send a command including a navigation number that can identify a stop pattern that is 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.

[0080] In contrast, in a game in which a stopping pattern that is 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 that notifies the player of that stopping pattern.

[0081] 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 (a display that displays "21" on the game auxiliary display 12) suggesting that the stop mode advantageous to the player is a stop operation sequence of center, right, left, 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 (a display that displays "23" on the game auxiliary display 12) suggesting that the stop mode advantageous to the player is a stop operation sequence of center, right, left, and during a game in which "2" is set as the navigation number, 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 2 (a display that displays "23" on the game auxiliary display 12) suggesting that the stop mode advantageous to the player is a stop operation sequence of center, right, left, and During a game in which "3" is set as the navigation number, navigation display 3 (a display that displays "31" on the gaming auxiliary display 12) is displayed on the gaming auxiliary display 12, suggesting that the stopping pattern that is 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 gaming auxiliary display 12) is displayed on the gaming auxiliary display 12, suggesting that the stopping pattern that is advantageous to the player is a stopping operation sequence of right, center, and left.

[0082] In response to this, the sub-control unit 91, during a game in which 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 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 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 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.

[0083] In this embodiment, the navigation notification is configured to notify the player of the stop operation sequence (correct push order) 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 operation mode can be suggested by displaying the number of a symbol corresponding to the predetermined operation timing on the game auxiliary display 12 together with the number corresponding to the predetermined reel, or by displaying an image of a symbol corresponding to the predetermined operation timing on the liquid crystal display 51 at a position corresponding to the predetermined reel.

[0084] [About the gaming area] As shown in FIG. 6, the main control unit 41 can control the gaming area to be either a normal area or an advantageous area.

[0085] The normal interval is a game interval in which no navigation notification is performed, and starts when the next game is started after the data related to the game (data indicating the game state, data indicating the game interval, BB winning flag, etc.) is initialized by a setting change, or after the advantageous interval ends. After that, the normal interval ends in a game in which the advantageous interval transition role is won by an internal lottery in a game controlled to a game state other than the special state.

[0086] The advantageous zone is a game zone in which a navigation notification may be issued, and is a game zone that is more advantageous to the player than the normal zone because the navigation notification may be executed. The advantageous zone begins when an internal lottery is drawn in a game in the normal zone that is controlled to a game state other than a special state, and a transition to the advantageous zone is determined, and the next game is started. The advantageous zone then ends when the end conditions of the advantageous zone (end conditions 1 and 2 described below) are met.

[0087] In the advantageous zone, when a predetermined notification condition is met (in this embodiment, the game is controlled to the AT state described below, and the navigation target role is won in an internal lottery), a navigation notification can be made, and when a navigation notification is made, the player is notified of the operation mode of the stop switches 8L, 8C, and 8R that is advantageous to the player.

[0088] The main control unit 41 controls the advantageous zone, and when it is controlled to an AT state in which a navigation notification is made, when a navigation target role is won in an internal lottery, it controls the navigation notification (control to display a navigation display on the game auxiliary 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.

[0089] The conditions for ending the advantageous zone include End Condition 1, which is met when the net increase in the number of medals in the advantageous zone (number of medals awarded minus number of medals used) exceeds a specified upper limit (2400 in this embodiment), and End Condition 2, which is met when a predetermined arbitrary condition is satisfied (in this embodiment, the remaining net increase in the number of medals (upper limit minus net increase in the advantageous zone) at the end of the AT2 state described below is equal to or less than a specific value (200 in this embodiment)). The advantageous zone ends when at least one of End Conditions 1 and 2 is met. The net increase in the number of medals in the advantageous zone is counted as a negative value, and if medals decrease, it can take on a negative value. In this case, the number of medals subsequently increases and recovers to 0, then becomes a positive value and exceeds the specified number, thereby fulfilling End Condition 1. Therefore, it is possible for the number of medals to increase by more than 2400 between the time the net increase in the number of medals in the advantageous zone, when it is a negative value, and the time End Condition 1 is fulfilled.

[0090] In this embodiment, when the gaming area is controlled to the normal area, the gaming area is transitioned to the favorable area by winning a predetermined favorable area transition role, but it may also be configured such that when the gaming area is controlled to the normal area, a favorable area transition lottery is held by winning a role eligible for the favorable area transition lottery in an internal lottery, and the gaming area is transitioned to the favorable area by winning the favorable area transition lottery.

[0091] 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, which is met when the number of games in the advantageous zone (number of games in the advantageous zone) reaches a specified number set as the upper limit (for example, 1500 games), or when any of these multiple conditions is met.

[0092] [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.

[0093] When a favorable zone transition role is won by an internal lottery in a game played within 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 the normal state, premonition state, CZ1 state, CZ2 state, AT1 state, AT2 state, and preparation state.

[0094] 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 that is entered after the normal state ends, and no navigation notification is performed, but the state always transitions to the CZ1 state afterwards, making it 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 the state can subsequently transition to the AT1 state, making it 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 the state can subsequently transition to the AT2 state, making it a more advantageous state for the player than the normal state and the premonition state. Furthermore, the CZ2 state is a state in which the probability of winning the AT lottery is higher than the CZ1 state, and as described below, when the AT lottery is won, the state transitions to the AT2 state, which is more advantageous than the AT1 state, making it 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 that, upon winning the AT lottery, the player transitions to the AT2 state, which is more advantageous than the AT1 state. However, it is sufficient that the CZ2 state is more advantageous than the CZ1 state in at least one of the following points: the probability of winning the AT lottery is higher than the CZ1 state; the player transitions to the AT2 state, which is more advantageous than the AT1 state, upon winning the AT lottery; and the ratio of players entering the AT2 state out of the AT1 and AT2 states is higher than the CZ1 state upon winning the AT lottery. 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. Furthermore, the AT2 state is more advantageous to the player than the AT1 state in that it is possible to expect a larger increase in medals than the AT1 state, the number of games can be increased, and the player is guaranteed to transition to the CZ2 state after the end of the AT2 state. The preparation state is a state in which no navigation notification is made, and is a state that is controlled before the CZ2 state begins if the advantageous zone continues after the end of the AT2 state.

[0095] Among these advantageous zone states, in the normal state, the premonition state, the CZ1 state, and the CZ2 state, in which no navigation notification is made, 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 completed, which will be described later, is not updated, and in the CZ1 state and the CZ2 state, the AT lottery is not performed even if the target role for the AT lottery is won. In addition, the sub-control unit 91 executes a warning notification informing the player 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 urging the player to play in a stop operation sequence in which the left reel is the first stop.

[0096] On the other hand, in the AT1 and AT2 states where the navigation notification is made, no penalty is given and no warning notification is issued even if a game is played in a stop operation sequence where a reel other than the left one comes to the first stop. Also, in the preparation state, although the navigation notification is not made, no penalty is given and no warning notification is issued even if a game is played in a stop operation sequence where a reel other than the left one comes to the first stop.

[0097] The main control unit 41 transitions the gaming zone to the advantageous zone when a beneficial zone transition role is won in the normal zone. At this time, it determines whether the gaming state is non-internal or internal, and if it is determined to be non-internal, it conducts a mode lottery and a game number lottery and controls the gaming zone to the normal state. When a BB is won in a non-internal zone, which transitions to the internal zone, the gaming zone will always transition to the advantageous zone, so the control to the normal zone in a non-internal zone occurs after the data related to the game (data indicating the gaming state, data indicating the gaming zone, BB winning flag, etc.) has been initialized due to a setting change. Therefore, when transitioning to the advantageous zone for the first time after a setting change, the gaming zone will first be controlled to the normal state.

[0098] The mode lottery determines the normal mode to be controlled thereafter. The game count lottery determines one of a number of game count ranges according to the mode determined in the mode lottery, and then determines the number of games to be played from the determined range.

[0099] The main control unit 41 adds the number of games played since the control was put into the normal state (referred to as the normal game number) for each game played in the normal state. The normal game number may be configured to add a specified value (for example, 1) for each game played, 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. Alternatively, the number of added games may be increased during a specific period.

[0100] The main control unit 41 determines whether the number of normal games after the addition has reached the number of games to be completed determined by the lottery for the number of games, and if the number of games to be completed has been reached, ends the normal state and controls the game to a premonition state for a predetermined period (16 to 32 games in this embodiment). Then, when the premonition state ends, the game is controlled to a CZ1 state.

[0101] 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 number of ending games 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 not only on the number of normal games reaching the number of ending games, but also on the normal state ending when the player wins the ending lottery held for each game or when a specific role is won or awarded, 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 player wins the ending lottery held for each game or when a specific role is won or awarded.

[0102] The CZ1 state is controlled for a maximum 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.

[0103] If the AT lottery is won within 20 games after the start of the CZ1 state, the main control unit 41 ends the CZ1 state and controls the next game to the AT1 state. On the other hand, if 20 games have passed without winning the AT lottery, the main control unit 41 ends the CZ1 state, then performs the mode lottery and game number lottery described above to determine the mode and number of games to end in the normal state, and controls the next game to the normal state.

[0104] 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 made, so you can expect an increase in medals.

[0105] When the AT1 state starts, the main control unit 41 first controls the game to be a point-up game, and after 15 games have passed, controls the game to be a condition determination game of up to 3 games.

[0106] In this embodiment, the number of games in the point-up game is 15, but the number of games in the point-up game can be varied by drawing a final lottery at a predetermined trigger in the point-up game (such as winning a specific role) or for each game, and by winning the final lottery the point-up game can be ended and controlled to a condition determination game, or by determining the number of games in the point-up game by drawing a lottery from among multiple game numbers.

[0107] 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 condition is deemed to have been met, and the AT1 state is terminated and control is exercised to switch to the AT2 state from the next game. On the other hand, if the condition determination lottery is not won even once, the condition is deemed not to have been met in that game, and the AT1 state is terminated, and the mode lottery and number of games to be played are performed as described above to determine the mode of the normal state and the number of games to be played, and control is exercised to switch to the normal state from the next game.

[0108] 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 advantageous 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.

[0109] In this embodiment, the configuration is such that the state is controlled to AT2 by achieving the conditions in the condition determination game in AT1 state, but it is also possible to configure the state to be controlled to AT2 by conducting an AT lottery in AT1 state and winning the AT lottery.

[0110] When the AT2 state starts, the main control unit 41 sets the initial value of the number of remaining games to 30. Then, the main control unit 41 subtracts 30 games from the number of remaining games for each game, and ends the AT2 state when the number of remaining games becomes 0.

[0111] In addition, when an add-on eligible role (a lottery role corresponding to FC4-6) is won in the AT2 state, the main control unit 41 conducts an add-on lottery to determine whether or not to add the remaining number of games and the number of games to be played. If the add-on lottery is won, the number of games won is added to the remaining number of games. Even when an add-on eligible role is won in the AT2 state, if the remaining net increase in coins (the upper limit minus the net increase in coins during the advantageous zone) is equal to or less than a specific number (200 in this embodiment), an add-on lottery is not conducted, limiting the addition of the remaining number of games. The specific number is a number greater than the number of medals expected to increase by adding the number of games when an add-on eligible role (a lottery role corresponding to FC6) that is expected to add the largest number of games is won. This makes it less likely that the net increase in coins during the advantageous zone will exceed the upper limit.

[0112] In this embodiment, when a role eligible for addition is won in the AT2 state, if the remaining net increase in the number of coins (maximum number of coins - net increase in the number of coins in the advantageous zone) is less than a specific number (200 in this embodiment), an addition lottery is not held. However, for example, a configuration may be adopted in which the number of roles eligible for addition lottery increases or the probability of winning the addition lottery is controlled, and in such a configuration, when the remaining net increase in the number of coins is less than a specific number in the AT2 state, the control of the addition state may be restricted, while an addition lottery is held when a role eligible for addition is won. Also, in a configuration in which control can be performed to multiple types of addition states with different expected numbers of games to be played, if the remaining net increase in the number of coins is less than a specific number in the AT2 state, only certain types of addition states with a relatively large number of games to be played may be restricted.

[0113] In addition, 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. When the right to win the AT is stocked, the sub-control unit 91 notifies the player of this fact and notifies the player of the number of remaining AT winning rights in an identifiable manner. Furthermore, 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 - net increase in the number of coins in the advantageous zone) is less than a specific number (200 in this embodiment), a stock lottery will not be conducted, and control of the AT2 state again is limited.

[0114] The main control unit 41 ends the AT2 state when the number of remaining games becomes 0 in 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 control is resumed 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 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), and if the remaining net increase is less than the specific number, it ends the advantageous zone and transitions the game zone to the normal zone. At this time, all data related to the AT (net increase 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 is not less than the specific number (exceeds the specific number), it controls to the preparation state from the next game while continuing the advantageous zone.

[0115] In this way, at the end of the AT2 state, it is determined whether the remaining net increase in the number of coins (maximum number of coins - net increase in the advantageous zone) 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 AT2 state rights through a stock lottery so as not to reach the maximum number of coins.

[0116] Furthermore, if the remaining net increase in coins (maximum number of coins - net increase in coins during the advantageous zone) is below a specific number (200 in this embodiment), and a large number of games is added at once, an increase of more than a specific number of medals may be expected. Even in situations where an increase of more than a specific number of medals is not expected due to the addition of the number of games, the game may be controlled to AT2 state again when the remaining net increase in coins is below a specific number due to the right to win an AT previously stocked. In such cases, even before the number of remaining games reaches 0 in the AT2 state, the net increase in coins during the advantageous zone may exceed the maximum number of coins, thereby establishing condition 1 for ending the advantageous zone.

[0117] Therefore, if the result of adding the remaining number of games in the additional lottery is that the sum of the net increase in the current advantageous zone and the net increase expected based on the current remaining number of games and the stocked AT rights exceeds the upper limit, the main control unit 41 controls the game to the ED state and continues the AT2 state regardless of the remaining number of games until the net increase in the advantageous zone exceeds the upper limit and the end condition 1 of the advantageous zone is met. When the end condition 1 is met, the main control unit 41 ends the AT2 state and the advantageous zone, transitioning the game zone to the normal zone. Additionally, all data related to the AT (such as the net increase in the advantageous zone, the number of points accumulated since the start of the advantageous zone, etc.) is initialized. Furthermore, when the sub-control unit 91 controls the game to the ED state, it executes an ED effect (FIG. 17(a)) that differs from the AT2 effect (FIG. 16(a)) described below. In the ED performance, the number of remaining games and the number of AT winning rights that are stocked, which are displayed in the AT2 performance, are not displayed, and the remaining number of medals to be added until the end condition 1 is met is announced.

[0118] When a beneficial zone transition role is won in the preparation state, if the beneficial zone transition role is a role eligible for AT lottery, the main control unit 41 will conduct an AT lottery and end the preparation state. The preparation state ends when a beneficial zone transition role is won, and is therefore controlled for a period of at least one game. If a beneficial zone transition role is won in the preparation state and the AT lottery is won, control will be made to the AT2 state again from the next game. Also, if the AT lottery is not won, control will be made to the CZ2 state from the next game. Also, if the beneficial zone transition role that was won is not an eligible role for AT lottery, i.e., if it is a push order role, control will be made to the CZ2 state from the next game without conducting an AT lottery.

[0119] The CZ2 state is controlled for a period of up to 20 games, during which the main control unit 41 conducts an AT lottery each time a role eligible for AT lottery is won. If the AT lottery is won within 20 games after the start of the CZ2 state, the main control unit 41 ends the CZ2 state and controls the next game to the AT2 state. On the other hand, if 20 games have passed without winning the AT lottery, the main control unit 41 ends the CZ2 state, then conducts the mode lottery and game number lottery described above to determine the subsequent normal state mode and the number of games to end, and controls the next game to the normal state.

[0120] Furthermore, when the main control unit 41 determines that the gaming state is in the internal state when a beneficial zone transition role is won in the normal zone and the game transitions to the beneficial zone, if the beneficial zone transition role is a role eligible for AT lottery, it will conduct an AT lottery. At this time, if the AT lottery is won, it will control to the AT2 state from the next game. If the AT lottery is not won, it will control to the CZ2 state from the next game. Furthermore, if the beneficial zone transition role that was won is not an eligible role for AT lottery, that is, if it is a push order role, it will control to the CZ2 state from the next game without conducting an AT lottery.

[0121] As mentioned above, when the BB win occurs during a non-internal period, the game always transitions to the advantageous zone. Therefore, when the game is controlled to the normal zone during an internal period, it is not the situation after the game-related data (data indicating the game status, data indicating the game zone, BB win flag, etc.) is initialized due to a setting change, but always the situation after the advantageous zone has ended. Furthermore, since the conditions for the end of the advantageous zone are rarely met in advantageous zone states other than the AT2 state, it is essentially the situation when the AT2 state ends and the game transitions to the normal zone. Therefore, when the AT2 state ends and the game transitions back to the advantageous zone, an AT lottery is held. If the AT lottery is won, the game will first be controlled to the AT2 state. If the AT lottery is not won (including when the advantageous zone transition role is a push order role), the game will first be controlled to the CZ2 state. After that, if the AT lottery is not won in the CZ2 state, the game will be controlled to the normal state.

[0122] [About the AT lottery] In this embodiment, as shown in FIG. 8, the AT lottery is triggered by the following events: 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 (when the favorable zone transition role is won (inside)); when a role eligible for AT lottery is won in the CZ2 state, which is controlled at the start of the favorable zone transitioned from the normal zone after the favorable zone ends with the end of the AT2 state (CZ2 state (start of favorable zone)); when a role eligible for AT lottery is won in the CZ1 state, which is controlled after the CZ2 state ends and passes through the normal state and premonition state (CZ1 state); when a favorable zone transition role is won, which triggers a transition from the preparation state to the CZ2 state while the favorable zone continues after the AT2 state ends (end of preparation state (when a favorable zone transition role is won)); when a role eligible for AT lottery is won in the CZ2 state, which is controlled after the AT2 state ends and the favorable zone continues (CZ2 state (1 to 3 times after the AT2 state ends), CZ2 state (4 times or more after the AT2 state ends)).

[0123] As shown in Figure 8, in the AT lottery when transitioning to a favorable zone (inside), the target AT state is the AT2 state, and if the favorable zone transition role belongs to FC1 (when a 1-piece small role is won), the winning probability is set to 10%, and if the favorable zone transition role belongs to FC3 to FC7 (when rare replay, rare small role A, rare small role B, rare small role C, rare small role D is won), the winning probability is set to 100%.

[0124] Also, as shown in Figure 8, in the AT lottery in the CZ2 state (at the start of the advantageous zone), the target AT state is the AT2 state, and the winning probability is set to 10% when the target role for the AT lottery belongs to FC1 (when a 1-piece small role is won), 25% when the target role for the AT lottery belongs to FC2 (when a normal replay is won), and 100% when the target role for the AT lottery belongs to FC3 to FC7 (when a rare replay, rare small role A, rare small role B, rare small role C, or rare small role D is won).

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

[0126] Also, as shown in Figure 8, in the AT lottery when the preparation state ends (when a favorable zone transition role is won), the target AT state is the AT2 state, and the winning probability is set to 10% when the favorable zone transition role belongs to FC1 (when a 1-piece small role is won), and 100% when the favorable zone transition role belongs to FC3 to FC7 (when a rare replay, rare small role A, rare small role B, rare small role C, or rare small role D is won).

[0127] Also, as shown in Figure 8, in the AT lottery in the CZ2 state after the end of the AT2 state, the target AT state is the AT2 state. Also, 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 or 4 or more times, and if the number of times controlled to the AT2 state after the AT1 state is 1 to 3 times, when the AT lottery target role belongs to FC1 (when 1 small role is won), the winning probability is 5%, when the AT lottery target role belongs to FC2 (when normal replay is won), the winning probability is 10%, when the AT lottery target role belongs to FC3 (when rare small role D is won), the winning probability is 12.5%, when the AT lottery target role belongs to FC4 (when rare small role C is won), the winning probability is 25%, when the AT lottery target role belongs to FC5 (when rare small role B is won), the winning probability is 10%. The probability of winning is 50%, if the target role for AT lottery belongs to FC6 (when rare replay is won), the probability of winning is 66%, if the target role for AT lottery belongs to FC7 (when rare small role A is won), the probability of winning is set to 100%.If the number of times controlled to AT2 state after AT1 state is 4 or more, if the target role for AT lottery belongs to FC1 (when 1 small role is won), the probability of winning is 10%, if the target role for AT lottery belongs to FC2 (when normal replay is won), the probability of winning is 25%, and if the target role for AT lottery belongs to FC3 to FC7 (when rare replay, rare small role A, rare small role B, rare small role C, rare small role D are won), the probability of winning is set to 100%.

[0128] In this embodiment, when a role eligible for AT lottery is won, an AT lottery is held in either 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, or the CZ1 state, which is controlled after the CZ2 state ends via the normal state and the precursor state. 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 advantageous than the AT1 state. After the advantageous zone starts and the CZ2 state ends, the player may 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.

[0129] In addition, the probability of winning the AT lottery is set higher when the AT lottery target role is won in the CZ2 state than when the AT lottery target role is won in the CZ1 state, and if the advantageous period ends when the AT2 state ends, it can be expected that when the advantageous period begins thereafter, the player will be controlled to the AT2 state, which is relatively more advantageous than the AT1 state, without going through the AT1 state.

[0130] In addition, in this embodiment, 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, or in either the CZ1 state which is controlled after the CZ2 state ends via the normal state and the precursor state, if a role eligible for AT lottery is won, an AT lottery is held. 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 at the time of the transition to the favorable zone, the player is controlled to the AT2 state which is relatively more favorable than the AT1 state. After the favorable zone begins and the CZ2 state ends, the player may be controlled to the AT2 state after the AT1 state, where more medals can be expected to be won than in the AT1 state. However, if the favorable zone has ended at the end of the AT2 state, when the favorable zone begins thereafter, the player can expect to be controlled to the AT2 state which is relatively more favorable than the AT1 state without going through the AT1 state.

[0131] In addition, the probability of winning the AT lottery is set to be higher if the target role for the AT lottery is won when the transition to the favorable zone occurs than when the target role for the AT lottery is won 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 going through the AT1 state.

[0132] Furthermore, during the AT lottery during the transition to the favorable zone (inside), the probability of winning the favorable zone transition role that is eligible for the AT lottery and winning the AT lottery is less than 50%. In other words, during the transition to the favorable zone, the probability of not being controlled to the AT state is higher than the probability of being controlled to the AT state. The rate of being controlled to the AT state upon transition to the favorable zone is suppressed, preventing excessive gambling. Also, in the favorable zone, there are roles that qualify for the AT lottery but do not result in a favorable zone transition role (normal replay). If such a role is won in the normal zone, there is no transition to the favorable zone and no AT lottery is performed. Therefore, the normal zone is not as advantageous as the favorable zone. Furthermore, roles that 100% win the AT lottery when drawn, such as FC3 to FC7, can be configured to be eligible for the AT lottery in the favorable zone but not result in a favorable zone transition role. This configuration further clarifies the difference in the degree of advantage between the normal zone and the favorable zone.

[0133] Furthermore, in this embodiment, in either the CZ2 state in which control is exercised while the advantageous zone continues after the AT2 state ends, or the CZ1 state in which control is exercised after the CZ2 state ends via the normal state and the premonition state, an AT lottery is held if a role eligible for AT lottery is won; however, if the AT lottery is won in the CZ1 state, control is exercised in the AT1 state, whereas if the AT lottery is won in the CZ2 state, control is exercised in the AT2 state, which is relatively more advantageous than the AT1 state; after the AT2 state ends, regardless of whether the advantageous zone has ended or not, it can be expected that control will be exercised in the AT2 state, which is relatively more advantageous than the AT1 state, without passing through the AT1 state.

[0134] In addition, the probability of winning the AT lottery is set to be higher when the AT lottery target role is won in the CZ2 state than when the AT lottery target role is won in the CZ1 state, and after the AT2 state ends, 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.

[0135] Furthermore, in this embodiment, when a favorable zone transition role is won, which triggers a transition from the preparation state to the CZ2 state while the favorable zone continues after the AT2 state ends, and when a role eligible for AT lottery is won in either the CZ1 state, which is controlled after the CZ2 state ends via the normal state and the premonition state, an AT lottery is held. 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 at the end of the preparation state (winning the favorable zone transition role), the player will be controlled to the AT2 state, which is relatively more favorable than the AT1 state. Therefore, regardless of whether the favorable zone has ended at the end of the AT2 state, when the favorable zone transition role is won for the first time after the end of the AT2 state, the player can expect to be controlled to the AT2 state, which is relatively more favorable than the AT1 state, without going through the AT1 state.

[0136] In addition, the probability of winning the AT lottery is set to be higher if the role eligible for the AT lottery is won at the end of the preparation state (winning the role that transitions to the advantageous zone) than if the role eligible for the AT lottery is won in the CZ1 state. Therefore, regardless of whether the advantageous zone has ended at the end of the AT2 state or not, when the role that transitions to the advantageous zone is first won after the end of the AT2 state, it can be expected that the player will be controlled to the AT2 state, which is relatively more advantageous than the AT1 state, without going through the AT1 state.

[0137] Furthermore, 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 game is won in the AT lottery, 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.

[0138] On the other hand, once the device is controlled to the AT2 state, after the AT2 state ends it will be put into the CZ2 state, which is likely to be controlled back to the AT2 state. Therefore, once the device is controlled to the AT2 state, it can be expected that the AT2 state will continue.

[0139] Furthermore, in the CZ2 state, which is controlled after the AT2 state ends, the probability of winning the AT lottery is set higher if the number of times the player has been controlled to the AT2 state after the AT1 state is four or more than if the number of times the player has been controlled to the AT2 state after the AT1 state is one to three. Therefore, if the number of times the player 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.

[0140] Also, in the AT2 state, if the net increase in the number of coins in the advantageous zone exceeds the upper limit and the advantageous zone ends with the AT2 state, and if the remaining net increase in coins falls below a specific number at the end of the AT2 state and the advantageous zone ends, the data related to the AT will be initialized, but then, at the start of the advantageous zone, the state will be changed to CZ2, 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 advantageous zone ends midway.

[0141] In addition, the advantageous 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 advantageous zone, the probability of winning the AT lottery is set higher when the number of times it has been controlled to the AT2 state after the AT1 state is one to three, just as when the number of times it has been controlled to the AT2 state after the AT1 state is four or more than when it has been controlled to the AT2 state after the AT1 state.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 advantageous zone ends midway.

[0142] 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 has ended with the end of the AT state, the main control unit 41 controls 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 to the CZ2 state at the start of the favorable zone, but controls to the normal state, so that even if the gaming parlor changes the setting, the game will not be intentionally controlled to the CZ2 state, which is advantageous to the player.

[0143] In addition, the main control unit 41 determines whether the game state is internal or non-internal at the time of transition to the advantageous zone, and thereby identifies whether the advantageous zone is one that was transitioned from the normal zone after the advantageous zone ended with the end of the AT2 state, or one that was transitioned to for the first time from the normal zone after the setting was 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 that was transitioned from the normal zone after the advantageous zone ended with the end of the AT2 state, or one that was transitioned to for the first time from the normal zone after the setting was changed.

[0144] [Regarding control at the start of CZ1 state] Next, the control at the start of the CZ1 state will be described with reference to FIGS.

[0145] As shown in Figure 9, 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 OFF, and the AT LED 19b also remains OFF.

[0146] 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, etc. is displayed, and the CZ1 effect is an effect in which a CZ1 background image, etc. specific to the CZ1 state is displayed.

[0147] After that, if the AT lottery is won in the CZ1 state, the main control unit 41 controls the next game to the AT1 state. At this time, the CZ·AT signal is kept on, and the AT signal is switched on, so that the CZ·AT LED 19a remains on, and the AT LED 19b is switched on from the unlit state.

[0148] In addition, the sub-control unit 91 switches from the CZ1 effect to the AT1 effect when the AT1 state begins. 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 coin number counter value, which counts the number of coins acquired during the series of ATs, is reset to 0, and an acquired coin number notification is started, which displays the acquired coin number counter value.

[0149] On the other hand, if the CZ1 state ends without a win in the AT lottery during 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 unlit state. In addition, the sub-control unit 91 switches from the CZ1 effect to the normal effect upon the end of the CZ1 state.

[0150] 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.

[0151] 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 coin count counter value is carried over, and the acquired coin count notification also continues.

[0152] On the other hand, as shown in Figure 10, if the condition is not met 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, when the CZ1 state ends, the sub-control unit 91 switches from the CZ1 effect to the normal effect, and the notification of the number of winning coins also ends.

[0153] [Control when AT2 state ends] Next, the control at the time of ending the AT2 state will be described with reference to FIGS.

[0154] 11, when the AT2 state ends and the advantageous zone is ended while the net increase in the advantageous zone is equal to or less than the upper limit, 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.

[0155] In addition, with the end of the AT2 state, the sub-control unit 91 ends the AT2 effect (Fig. 16(a)), executes a result notification effect (Fig. 16(b)) that notifies the results of the net increase in 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. After that, triggered by the start operation of the next game, the result notification effect (Fig. 16(b)) is switched to a standby effect (Fig. 16(c)). The standby effect is an effect in which standby images, etc. are displayed.

[0156] After that, when the main control unit 41 wins a role that transitions to an advantageous zone during the normal zone, the normal zone ends and the advantageous zone starts from the next game. If the AT lottery held at this time is not won, the main control unit 41 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.

[0157] In addition, when the CZ2 state starts, the sub-control unit 91 switches from the standby effect (FIG. 16(c)) to the CZ2 effect (FIG. 16(d)). The CZ2 effect is an effect in which a CZ2 background image specific to the CZ2 state is displayed.

[0158] On the other hand, if the AT lottery is won during the transition of the advantageous zone, the main control unit 41 controls the game to the AT2 state when the advantageous zone starts. At this time, the CZ·AT signal and the AT signal are switched from the OFF state to the ON state, and the CZ·AT LED 19a and the AT LED 19b are switched from the OFF state to the ON state.

[0159] In addition, the sub-control unit 91 switches from the standby effect (Fig. 16(c)) to the AT2 effect (Fig. 16(a)) when the AT2 state starts. The acquired coin number counter value is carried over without being initialized even when the advantageous zone ends at the end of the previous AT2 state, and when the AT2 effect starts, the acquired coin number notification is started based on the acquired coin number counter value carried over and counted from the end of the previous AT2 state.

[0160] If the AT lottery is won in the CZ2 state, the main control unit 41 controls the next game to the AT2 state. At this time, the CZ AT signal is kept on, the AT signal is switched from off to on, the CZ AT LED 19a is kept on, and the AT LED 19b is switched on from off to on.

[0161] In addition, the sub-control unit 91 switches from the CZ2 effect (Fig. 16(d)) to the AT2 effect (Fig. 16(a)) when the AT2 state starts. The acquired coin number counter value is carried over without being initialized even when the advantageous zone ends at the end of the previous AT2 state, and when the AT2 effect starts, notification of the acquired coin number is started based on the acquired coin number counter value carried over and counted from the end of the previous AT2 state.

[0162] On the other hand, as shown in Figure 13, if the CZ2 state ends without a win in the AT lottery during the CZ2 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. In addition, the sub-control unit 91 switches from the CZ2 effect (Figure 16(d)) to the normal effect (Figure 16(e)) upon the end of the CZ2 state.

[0163] 12, when the AT2 state ends and the advantageous zone continues, the main control unit 41 controls the next game to the ready state. At this time, just as when the advantageous zone ends, 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 unlit state.

[0164] In addition, when the AT2 state ends, the sub-control unit 91 ends the AT2 effect (FIG. 16(a)), executes the result notification effect (FIG. 16(b)), and accordingly ends the notification of the number of coins won. After that, in response to the start operation of the next game, the result notification effect (FIG. 16(b)) is switched to the standby effect (FIG. 16(c)), just as when the game transitions to the normal zone.

[0165] After that, the main control unit 41 ends the preparation state when a role that transitions to an advantageous zone is won in the preparation state. If the AT lottery held at this time is not won, control is made to the CZ2 state from the next game. 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.

[0166] In addition, the sub-control unit 91 switches from the standby effect (FIG. 16(c)) to the CZ2 effect (FIG. 16(d)) upon the start of the CZ2 state.

[0167] On the other hand, if the AT lottery is won at the end of the preparation state, the main control unit 41 controls the next game to AT2 state. At this time, the CZ AT signal and AT signal are switched from OFF to ON, and the CZ AT LED 19a and AT LED 19b are switched from OFF to ON.

[0168] In addition, the sub-control unit 91 switches from the standby effect (Fig. 16(c)) to the AT2 effect (Fig. 16(a)) when the AT2 state starts. The acquired coin number counter value is carried over without being initialized even when the advantageous zone ends at the end of the previous AT2 state, and when the AT2 effect starts, the acquired coin number notification is started based on the acquired coin number counter value carried over and counted from the end of the previous AT2 state.

[0169] If the AT lottery is won in the CZ2 state, the main control unit 41 controls the next game to the AT2 state. At this time, the CZ AT signal is kept on, the AT signal is switched from off to on, the CZ AT LED 19a is kept on, and the AT LED 19b is switched on from off to on.

[0170] In addition, the sub-control unit 91 switches from the CZ2 effect (Fig. 16(d)) to the AT2 effect (Fig. 16(a)) when the AT2 state starts. The acquired coin number counter value is carried over without being initialized even when the advantageous zone ends at the end of the previous AT2 state, and when the AT2 effect starts, notification of the acquired coin number is started based on the acquired coin number counter value carried over and counted from the end of the previous AT2 state.

[0171] On the other hand, as shown in Figure 14, if the CZ2 state ends without a win in the AT lottery during the CZ2 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. In addition, the sub-control unit 91 switches from the CZ2 effect (Figure 16(d)) to the normal effect (Figure 16(e)) upon the end of the CZ2 state.

[0172] As shown in Figure 15, even if the main control unit 41 controls the game to the aforementioned ED state by adding the remaining number of games, resulting in the net increase in the advantageous zone exceeding the upper limit, ending the AT2 state and ending the advantageous zone, the sub-control unit 91 transitions to the normal zone from the next game. At this time, the sub-control unit 91 starts the ED effect (Figure 17(a)) with the start of the ED state, and ends the ED effect (Figure 17(a)) with the end of the AT2 state. In addition to the results of the net increase in the number of coins during the series of AT periods (the period from the AT1 state) and the number of games controlled by the AT, the result notification / advantageous zone end effect (Figure 17(b)) is executed to notify the player that the advantageous zone has ended because the net increase in coins has exceeded the upper limit of the advantageous zone, and the notification of the number of coins won is accordingly terminated. Then, upon the start operation of the next game, the result notification / advantageous zone end effect (Figure 17(b)) is switched to the normal effect (Figure 17(c)).

[0173] Thereafter, when a winning combination for transitioning to an advantageous zone is achieved during the normal zone, the main control unit 41 ends the normal zone and starts the advantageous zone from the next game. If the AT lottery held at this time is not won, control is exercised to enter the CZ2 state at the start of the advantageous zone. At this time, the sub-control unit 91 executes a revival effect (FIG. 17(d)) ​​with the start of the CZ2 state, and then switches to the CZ2 effect (FIG. 17(e)).

[0174] On the other hand, if the AT lottery is won during the transition to the advantageous zone, the main control unit 41 controls to the AT2 state at the start of the advantageous zone. At this time, the sub-control unit 91 executes a revival effect (Fig. 17(d)) ​​with the start of the AT2 state, and then switches to the AT2 effect. The acquired coin 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 effect, an announcement of the acquired coin number is started based on the acquired coin number counter value carried over and counted from the end of the previous AT2 state.

[0175] If the AT lottery is won in the CZ2 state, the main control unit 41 controls the next game to the AT2 state. At this time, the sub-control unit 91 switches from the CZ2 presentation (Fig. 17(e)) to the AT2 presentation as the AT2 state begins. The acquired coin 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, the acquired coin number notification begins based on the acquired coin number counter value carried over and counted from the end of the previous AT2 state.

[0176] On the other hand, if the CZ2 state ends without winning the AT lottery during the CZ2 state, the main control unit 41 controls the next game to the normal state. At this time, the sub-control unit 91 switches from the CZ2 effect (FIG. 17(e)) to the normal effect (FIG. 17(f)) upon the end of the CZ2 state.

[0177] 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 result in the player being 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 the player is controlled to the CZ2 state when the advantageous zone is again entered. If the advantageous zone continues and the player is controlled to the CZ2 state, the player is controlled to the CZ2 state after passing through a preparation state. If the advantageous zone ends and the player transitions to the advantageous zone again after the AT2 state ends and the player is controlled to the CZ2 state, there is always a waiting period after the AT2 state ends and before the CZ2 state starts. However, even if 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 after passing through 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 has once ended.

[0178] In addition, in the normal zone, when a favorable zone transition role is won, the player is transitioned to the favorable zone, and even in the preparation state, which is controlled when the favorable zone continues and the player is controlled to the CZ2 state, when a favorable zone transition role is won, the preparation state is ended and the player is controlled to the CZ2 state.If the favorable zone continues and the player is controlled to the CZ2 state, the player will be controlled to the CZ2 state at the same trigger as when the favorable zone ends and the player is controlled to the CZ2 state, making it difficult to determine whether the player was controlled to the CZ2 state while the favorable zone continued, or whether the player was controlled to the CZ2 state after the favorable zone ended.

[0179] Furthermore, in the normal zone, no control related to the AT is carried out, 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 zone, there is no change in the degree of advantage related to the AT, and no warning notification is issued for the AT, making it difficult to determine whether the advantageous zone continued and the game was controlled to the CZ2 state, or whether the advantageous zone ended once and the game was controlled to the CZ2 state.

[0180] Also, when the AT2 state ends and the advantageous period ends, the CZ·AT signal and AT signal will turn off once, and after the transition to the advantageous period and the start of the CZ2 state, the CZ·AT signal and AT signal will change to the on state again; however, even in cases where the advantageous period continues and the game is controlled to the CZ2 state, the CZ·AT signal and AT signal will turn off once in the preparation state, and then will remain off for at least one game, and after the CZ2 state starts, the CZ·AT signal and AT signal will change to the on state again; even in cases where the advantageous period continues and the game is controlled to the CZ2 state, the CZ·AT signal and AT signal will turn off once, just as in cases where the advantageous period has ended and the game has been controlled to the CZ2 state, making it difficult to determine whether the advantageous period continued and the game was controlled to the CZ2 state, or whether the advantageous period had ended and the game was controlled to the CZ2 state once.

[0181] In particular, when the advantageous period continues, the CZ·AT signal will remain on when switching from one state to another, such as when transitioning from CZ1 state to AT1 state, when transitioning from AT1 state to AT2 state, or when transitioning from CZ2 state to AT2 state, in all cases where the CZ·AT signal is on. However, when switching from AT2 state to CZ2 state in a situation where the advantageous 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 advantageous period continued and the CZ state was maintained, or whether the advantageous period ended and the CZ state was maintained.

[0182] Also, when the AT2 state ends and the advantageous period ends, the LED 19a during CZ·AT and the LED 19b during AT will go from the lit state to the non-lit state once, and after the transition to the advantageous period and the start of the CZ2 state, the LED 19a during CZ·AT and the LED 19b during AT will change to the lit state again, but even if the advantageous period continues and is controlled to the CZ2 state, the LED 19a during CZ·AT and the LED 19b during AT will go from the lit state to the non-lit state once in the preparation state, and then will remain non-lit for at least one game. After the LEDs are lit, once the CZ2 state begins, LED 19a during CZ·AT and LED 19b during AT will change to a lit state again, and 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 temporarily become unlit, just as in the case where the advantageous period has ended and the game has been controlled to the CZ2 state, making it difficult to determine whether the advantageous period continued and the game was controlled to the CZ2 state, or whether the advantageous period had ended and the game was controlled to the CZ2 state.

[0183] In particular, when the advantageous period continues, the CZ·AT LED 19a will continue to be lit when switching from one state to the other, such as when transitioning from CZ1 state to AT1 state, when transitioning from AT1 state to AT2 state, or when transitioning from CZ2 state to AT2 state, but when switching from AT2 state to CZ2 state when the advantageous period continues, a preparation state will be inserted, during which time the CZ·AT LED 19a will be temporarily unlit, 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.

[0184] In addition, 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 also notifies the player of the number of remaining rights to win the AT in an identifiable manner, and if the right to win the AT is stocked at the end of the AT2 state, the game will be controlled again 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.

[0185] Furthermore, in this embodiment, the sub-control unit 91 is provided with an acquired coin counter value that counts the number of coins acquired during a series of ATs (the period from the start of the AT1 state until the CZ2 state ends without winning the AT lottery), and in the AT1 presentation during the AT1 state and the AT2 presentation during the AT2 state, an acquired coin count notification is executed that notifies the number of medals acquired during the series of ATs based on the acquired coin count counter value. Furthermore, when the AT2 state ends, the advantageous zone ends, and the game transitions to the normal zone, the acquired coin count counter value is carried over without being reset, and thereafter, when the game wins the AT lottery during the transition to the advantageous zone or in the CZ2 state that is controlled first after the transition to the advantageous zone, and the game is controlled to the AT2 state, an acquired coin count notification is executed based on the acquired coin count counter value that has been carried over and counted from the AT2 state before the advantageous zone ended, so that it is possible to make the AT2 state appear to be occurring continuously even when the advantageous zone is interrupted.

[0186] In addition, 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, and after the advantageous zone is ended, a new advantageous zone starts and the CZ2 state or AT2 state begins, the sub-control unit 91 executes a result notification effect (FIG. 16(b)) at the end of the AT2 state and advantageous zone, and then executes a standby effect (FIG. 16(c)) in the normal zone, just as in the case where the advantageous zone continues, and when the CZ2 state or AT2 state begins, it switches from the standby effect (FIG. 16(c)) to the CZ2 effect (FIG. 16(d)) or AT2 effect (FIG. 16(a)), but as a result of the number of games being added, it is controlled to the ED state, and the net increase in the number of coins in the advantageous zone exceeds the upper limit. When the number of coins exceeds the upper limit of the advantageous zone and the AT2 state ends, and after that a new advantageous zone begins and the CZ2 state or AT2 state begins, unlike when the advantageous zone continues, an ED effect (Figure 17(a)) is executed as soon as control of the ED state begins, and at the end of the AT2 state and advantageous zone, in addition to the result notification, a result notification / advantageous zone end effect (Figure 17(b)) is executed to notify that the advantageous zone has ended as the net increase in coins has exceeded the upper limit of the advantageous zone, and thereafter a normal effect is executed in the normal zone, and when the CZ2 state or AT2 state begins, a revival effect (Figure 17(d)) ​​is executed before switching to a CZ2 effect (Figure 17(e)) or AT2 effect. 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 is different from when the net increase in the number of coins in the advantageous zone ends without exceeding the upper limit number, and a new advantageous zone begins, thereby reducing the sense of discomfort that the AT2 state continues even though the net increase in the number of coins in the advantageous zone exceeds the upper limit number and the advantageous zone ends.

[0187] [Effect 1] In this embodiment, when a role eligible for AT lottery is won, an AT lottery is held in either 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, or the CZ1 state, which is controlled after the CZ2 state ends via the normal state and premonition state. 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 advantageous than the AT1 state. After the advantageous zone starts and the CZ2 state ends, the player may 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 going through the AT1 state.

[0188] 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, but it 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.

[0189] Furthermore, 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 at the start of the advantageous zone, but it is also possible to configure the AT lottery in the CZ1 state so that both the AT1 state and the AT2 state are the subject of the lottery, or the AT lottery in the CZ2 state at the start of the advantageous zone so that both the AT1 state and the AT2 state are the subject of the lottery, or the AT lottery in the CZ1 state and the AT lottery in the CZ2 state at the start of the advantageous zone so that both the AT1 state and the AT2 state are the subject of the lottery. Even with such a configuration, for example, as shown in Figure 18, in the AT lottery when the AT lottery target role is won in the CZ1 state, the probability of winning is set so that the AT1 state is higher than the AT1 state, and in the AT lottery when the AT lottery target role is won in the CZ2 state at the start of the advantageous period, the probability of winning is set so that the AT2 state is higher than the AT1 state.If the advantageous period has ended at the end of the AT2 state, it can be expected that when the advantageous period begins 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.

[0190] Furthermore, in this embodiment, after the transition to the advantageous zone and the end of the CZ2 state, the AT lottery is not conducted in the normal state and premonition state until it is controlled to the CZ1 state. However, it is also possible to configure the AT lottery to be conducted if the role subject to the AT lottery is won in the normal state and premonition state until it is controlled to the CZ1 state. Even in such a configuration, the AT lottery in the normal state and premonition state is configured so that only the AT1 state is won, or the winning probability is set so that the proportion of winning the AT1 state between the AT1 state and the AT2 state is higher. In addition, in the AT lottery in the CZ2 state at the start of the advantageous zone, the AT lottery is configured so that only the AT2 state is won, or the winning probability is set so that the proportion of winning the AT2 state between the AT1 state and the AT2 state is higher. In this way, if the advantageous zone has ended at the end of the AT2 state, it can be expected that when the advantageous zone begins thereafter, it will be controlled to the AT2 state, which is relatively more advantageous than the AT1 state, without going through the AT1 state.

[0191] In this embodiment, when a role that is subject to AT lottery is won, an AT lottery is held when a role that transitions from the normal zone to the favorable zone after the favorable zone ends with the end of the AT2 state is won, and when a role that is subject to AT lottery is won in either the CZ1 state that is controlled after the CZ2 state ends and passes through the normal state and the premonition state. 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 at the time of the transition to the favorable zone, the player is controlled to the AT2 state, which is relatively more favorable than the AT1 state. After the favorable zone starts and the CZ2 state ends, the player can be controlled to the AT2 state after the AT1 state, where more medals can be expected to be won than in the AT1 state. However, if the favorable zone has ended at the end of the AT2 state, when the favorable zone starts thereafter, the player can expect to be controlled to the AT2 state, which is relatively more favorable than the AT1 state, without going through the AT1 state.

[0192] 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 has ended 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 has been 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 has been changed.

[0193] Furthermore, 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 when transitioning to an advantageous zone, but it is also possible to configure the AT lottery in the CZ1 state so that both the AT1 state and the AT2 state are the subject of the AT lottery, or to configure the AT lottery when transitioning to an advantageous zone so that both the AT1 state and the AT2 state are the subject of the lottery, or to configure the AT lottery in both the CZ1 state and the AT lottery when transitioning to an advantageous zone so that both the AT1 state and the AT2 state are the subject of the lottery. Even with such a configuration, for example, as shown in Figure 18, in the AT lottery when the AT lottery target role is won in the CZ1 state, the probability of winning is set so that the AT1 state is higher than the AT1 state, and in the AT lottery when the AT lottery target role is won at the time of transition to the advantageous zone, the probability of winning is set so that the AT2 state is higher than the AT1 state.In this way, if the advantageous zone has ended at the end of the AT2 state, it can be expected that when the advantageous zone begins 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.

[0194] Furthermore, even if the AT lottery is configured so that it is held when the role eligible for AT lottery is won 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 AT1 state is won, or the winning probability is set so that the proportion of winning the AT1 state is higher between the AT1 state and the AT2 state, and the AT lottery when transitioning to the favorable zone is configured so that only the AT2 state is won, or the winning probability is set so that the proportion of winning the AT2 state is higher between the AT1 state and the AT2 state.In this way, if the favorable zone has ended when the AT2 state ends, it can be expected that when the favorable zone begins thereafter, it will be controlled to the AT2 state, which is relatively more favorable than the AT1 state, without passing through the AT1 state.

[0195] In this embodiment, an AT lottery is held if a role eligible for AT lottery is won in either the CZ2 state, which is controlled while the advantageous zone continues after the AT2 state ends, or the CZ1 state, which is controlled after the CZ2 state ends via the normal state and premonition state. 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 advantageous than the AT1 state. After the AT2 state ends, regardless of whether the advantageous zone has ended or not, 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.

[0196] 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 has ended; however, it is also possible to configure the AT lottery in the CZ1 state so that both the AT1 state and the AT2 state are the subject of the AT lottery, or to configure the AT lottery in the CZ2 state after the AT2 state has ended so that both the AT1 state and the AT2 state are 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 has ended so that both the AT1 state and the AT2 state are the subject of the AT lottery. Even with such a configuration, for example, as shown in Figure 18, in the AT lottery when a role eligible for AT lottery is won in the CZ1 state, the probability of winning is set so that the AT1 state is more likely to be won than the AT2 state, and in the AT lottery when a role eligible for AT lottery is won in the CZ2 state after the AT2 state has ended, the probability of winning is set so that the AT2 state is more likely to be won than the AT1 state, so that after the AT2 state has ended, 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.

[0197] Furthermore, even if the AT lottery is configured so that it is held when the AT lottery target role is won 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 AT1 state is won, or the winning probability is set so that the proportion of winning the AT1 state is higher between the AT1 state and the AT2 state, and the AT lottery in the CZ2 state after the AT2 state ends is configured so that only the AT2 state is won, or the winning probability is set so that the proportion of winning the AT2 state is higher between the AT1 state and the AT2 state, by doing so, after the AT2 state ends, regardless of whether the advantageous zone has ended or not, it can be expected that it will be controlled to the AT2 state, which is relatively more advantageous than the AT1 state, without passing through the AT1 state.

[0198] In this embodiment, the sub-control unit 91 is equipped with an acquired number counter value that counts the number of medals acquired during a series of ATs (the period from the start of the AT1 state until the end of the CZ2 state without winning the AT lottery), and in the AT1 presentation during the AT1 state and the AT2 presentation during the AT2 state, an acquired number notification is executed to notify the number of medals acquired during a series of ATs based on the acquired number counter value, and when the AT2 state ends, the advantageous zone ends, and the normal zone is entered, the acquired number counter value is carried over without being reset, and thereafter, when the advantageous zone is entered or in the CZ2 state that is controlled first after the advantageous zone is entered, the AT lottery is won and the AT2 state is entered, the acquired number notification is executed based on the acquired number counter value that has been carried over and counted from the AT2 state before the advantageous zone ended, so that it can be made to appear as if the AT2 state is occurring continuously even when the advantageous zone is interrupted.

[0199] In this embodiment, the number of coins won is notified during the AT1 effect during the AT1 state and the AT2 effect during the AT2 state, but the number of coins won may also be notified during the CZ2 effect during the CZ2 state.

[0200] 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 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 AT2 state rights through a stock lottery so as not to reach the maximum number of coins.

[0201] 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, and after the advantageous zone is ended, a new advantageous zone starts and the CZ2 state or AT2 state begins, the sub-control unit 91 executes a result notification effect (Fig. 16(b)) at the end of the AT2 state and advantageous zone, just as in the case where the advantageous zone continues, and then executes a standby effect (Fig. 16(c)) in the normal zone, and when the CZ2 state or AT2 state begins, it switches from the standby effect (Fig. 16(c)) to the CZ2 effect (Fig. 16(d)) or AT2 effect (Fig. 16(a)). However, when the number of games is added, the control is made to the ED state, and the net increase in the number of coins in the advantageous zone exceeds the upper limit, the AT2 state ends, and after the advantageous zone is ended, a new advantageous zone starts and the CZ2 state or AT2 state begins. Unlike the case where the advantageous zone continues, when the control of the ED state begins, An ED effect (Figure 17(a)) is executed, and at the end of the AT2 state and advantageous zone, in addition to the result notification, a result notification / advantageous zone end effect (Figure 17(b)) is executed to notify 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, in the normal zone, a normal effect (Figure 17(c)) is executed, and when the CZ2 state or AT2 state begins, a revival effect (Figure 17(d)) ​​is executed, and then a switch is made to a CZ2 effect (Figure 17(e)) or AT2 effect. When the net increase in the number of coins in the advantageous zone exceeds the upper limit and the advantageous zone ends, and a new advantageous zone begins, the effect is different from when the net increase in the number of coins in the advantageous zone ends without exceeding the upper limit, and then a new advantageous zone begins. Therefore, it is possible to reduce the sense of discomfort felt when the AT2 state continues even though the net increase in the number of coins in the advantageous zone has exceeded the upper limit and the advantageous zone has ended.

[0202] As shown in Figure 19, when the net increase in the number of coins in the advantageous zone exceeds the upper limit, the AT2 state ends, and after the advantageous zone ends, a new advantageous zone begins and the CZ2 state or AT2 state begins, at the end of the AT2 state and advantageous zone, the result notification / advantageous zone end effect (Figure 17(b)) is executed, and then in the normal zone, the normal effect (Figure 17(c)) is executed, and even in the CZ2 state after transition to the advantageous zone, the normal effect (Figure 17(c)) continues to be executed, and when the AT lottery is won in the CZ2 state and the AT2 state begins, the normal effect (Figure 17(c)) can be switched from the normal effect to the AT2 effect. With this configuration, when the net increase in the number of coins in the advantageous zone exceeds the upper limit and the advantageous zone ends, there is little connection with the subsequent AT2 state, so it is possible to reduce the sense of discomfort that the AT2 state continues even though the net increase in the number of coins in the advantageous zone exceeds the upper limit and the advantageous zone ends. Furthermore, in such a configuration, if the AT lottery is won when the advantageous zone transition occurs, the configuration may be such that the normal presentation is switched to the AT2 presentation when the AT2 state begins, and if the CZ2 state ends without winning the AT lottery after the transition to the advantageous zone, the normal presentation may continue. Furthermore, in such a configuration, if the AT lottery is won during the transition to the advantageous zone or in the CZ2 state after the transition to the advantageous zone and the AT2 state is entered, 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 advantageous zone. With this configuration, if the net increase in the advantageous zone exceeds the upper limit and the advantageous zone ends, the relationship with the subsequent AT2 state becomes even weaker, and the sense of incongruity caused by the AT2 state continuing anew despite the net increase in the advantageous zone exceeding the upper limit and the advantageous zone ending can be further alleviated.

[0203] [Effect 2] In this embodiment, after the AT2 state ends, there are cases where the system is controlled to the CZ2 state while the advantageous zone continues and there is a high possibility that the system will be controlled to the AT2 state, and cases where the system is controlled to the CZ2 state when the advantageous zone ends and the system transitions to the normal zone after the AT2 state ends and then transitions back to the advantageous zone. If the system is controlled to the CZ2 state while the advantageous zone continues, it is controlled to the CZ2 state after passing through a preparation state. If the system is controlled to the CZ2 state when the advantageous zone ends and the system transitions back to the advantageous zone after the AT2 state ends, there is always a waiting period after the AT2 state ends and before the CZ2 state starts. However, even if the system is controlled to the CZ2 state while the advantageous zone continues, the CZ2 state does not start immediately, but is controlled to the CZ2 state after passing through a preparation state for a predetermined period, making it difficult to determine whether the system was controlled to the CZ2 state while the advantageous zone continued or whether the system was controlled to the CZ2 state after the advantageous zone ended.

[0204] In this embodiment, in the normal zone, when a role that transitions to a favorable zone is won, the zone is transitioned to the favorable zone, and even in the preparation state that is controlled when the favorable zone continues and the zone is controlled to the CZ2 state, when a role that transitions to a favorable zone is won, the preparation state is ended and the zone is controlled to the CZ2 state.If the favorable zone continues and the zone is controlled to the CZ2 state, the zone will be controlled to the CZ2 state at the same trigger as when the favorable zone ends once and the zone is controlled to the CZ2 state, making it difficult to determine whether the zone was controlled to the CZ2 state while the favorable zone continued, or whether the zone was controlled to the CZ2 state after the favorable zone ended once.

[0205] In this embodiment, in the normal zone, no control related to the AT is performed, and even if the 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 in relation to the AT and no warning notification is issued.However, even if the game is played in a stop 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 zone, 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 zone continued and the game was controlled to the CZ2 state, or whether the advantageous zone ended once and the game was controlled to the CZ2 state.

[0206] In this embodiment, when the AT2 state ends and the advantageous period ends, the CZ·AT signal and AT signal are turned off once, and after the advantageous period begins and the CZ2 state begins, the CZ·AT signal and AT signal are turned on again. However, even when the advantageous period continues and the game is controlled to the CZ2 state, the CZ·AT signal and AT signal are turned off once in the preparation state, and then they remain off for at least one game, and after the CZ2 state begins, the CZ·AT signal and AT signal are turned on again. Even when the advantageous period continues and the game is controlled to the CZ2 state, the CZ·AT signal and AT signal are turned off once, just as when 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 once.

[0207] In this embodiment, when the AT2 state ends and the advantageous period 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 advantageous period has started and the CZ2 state has begun, the CZ·AT LED 19a and the AT LED 19b will again change to the lit state. However, even if the advantageous period continues and the CZ2 state is controlled, the CZ·AT LED 19a and the AT LED 19b will go from the lit state to the non-lit state once in the preparation state, and then for at least one game. After they have become non-illuminated, LED 19a during CZ·AT and LED 19b during AT will change to a lit state again after the CZ2 state begins, and even if the advantageous period continues and the game is controlled to CZ2 state, LED 19a during CZ·AT and LED 19b during AT will temporarily become non-illuminated, just as in the case where the advantageous period has ended and the game is controlled to CZ2 state, making it difficult to determine whether the advantageous period continued and the game was controlled to CZ2 state, or whether the advantageous period had ended and the game was controlled to CZ2 state.

[0208] In this embodiment, the sub-control unit 91 is equipped with an acquired number counter value that counts the number of medals acquired during a series of ATs (the period from the start of the AT1 state until the end of the CZ2 state without winning the AT lottery), and in the AT1 presentation during the AT1 state and the AT2 presentation during the AT2 state, an acquired number notification is executed to notify the number of medals acquired during a series of ATs based on the acquired number counter value, and when the AT2 state ends, the advantageous zone ends and the game transitions to the normal zone, the acquired number counter value is carried over without being reset, and thereafter, when the game transitions to the advantageous zone or in the CZ2 state that is controlled first after the transition to the advantageous zone, if the game wins the AT lottery and is controlled to the AT2 state, an acquired number notification is executed based on the acquired number counter value carried over from the AT2 state before the end of the advantageous zone, so that it can be made to appear as if the AT2 state is occurring continuously even when the advantageous zone is interrupted.

[0209] 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, and if the right to win 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.

[0210] In this embodiment, when the right to win the AT is stocked, the fact is notified, and the number of remaining AT winning rights is also notified in an identifiable manner. However, it is not necessary for all rights to be notified in an identifiable manner, and only some of the 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. If the right to win the AT is stocked but the right to win the AT is not notified in an identifiable manner, the game may be controlled to the AT2 state after going through the preparation state or CZ2 state and then consuming the stock. By using such a configuration, even if the AT2 state does not start immediately after the end of the AT2 state, it is possible to expect that the right to win the AT is stocked.

[0211] Although an embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to this embodiment, and it goes without saying that modifications and additions that do not deviate from the spirit of the present invention are also included in the present invention.

[0212] In the above embodiment, an example was described in which the present invention is applied to a slot machine in which the number of bets is set using medals and credits as gaming value, but it may also be applied to a slot machine in which the number of bets is set using gaming balls as gaming value, or to a medal-free slot machine in which the number of bets is set using only credits, without using medals as gaming value.
