Description

[Technical field]

[0001] Concerning gaming machines. [Background technology]

[0002] In a slot machine, a game starts when a start command device (start lever) is operated after a predetermined number of game medals are inserted, and multiple rows of reels with multiple symbols arranged on the outer periphery rotate. When the reels are stopped by using a reel stop device (stop button) to stop the rotation, and a combination of predetermined symbols (for example, a winning combination such as "777") is lined up on an active line, the machine generally transitions to a special game state (a game state in which the probability of winning a small role is higher than usual) that is more profitable for the player than the normal game state. Here, in a slot machine, images for presentation to enhance the interest of the game may be displayed on a display such as a liquid crystal display in synchronization with the rotation and stopping of the reels, and many of these machines are configured so that when the reel stop device is operated, the player can enjoy predicting the outcome of the game by comparing the symbols displayed on the reels with the presentation images displayed on the display. Furthermore, many gaming machines are configured so that if any abnormality occurs in the machine, an error can occur that will stop the game from progressing.

MODE FOR CARRYING OUT THE INVENTION

[0008] First, the meaning of each term in this specification will be explained. A "random number" is a random number used in a lottery (a lottery by electronic computer, sometimes called a lottery) to determine the content of a game in a slot machine, and includes pseudo-random numbers in addition to random numbers in the narrow sense (for example, random numbers include hard random numbers, built-in random numbers generated by a main control chip including a CPU, and pseudo-random numbers include software random numbers). For example, so-called "basic random numbers" that affect the outcome of a game, specifically, "winning random numbers" related to special roles for moving to a special game and winning roles (small roles, replay roles), etc. can be mentioned. A "CPU" is synonymous with a well-known term in this industry, and is not limited in any way to the architecture (CISC, RISC, number of bits, etc.) or processing performance used. "Power interruption (power cut)" refers to the power supply voltage supplied to the gaming machine dropping below a certain level, regardless of whether the power switch on the gaming machine is operated or not, and includes the cutoff of the power supply due to unforeseen circumstances such as damage to the power supply unit or a power outage. "ROM" is synonymous with what is well known in the industry, and stores information physically (for example, when a current for reading data is applied, if the element configuration is conductive, it becomes "1", and if the element configuration is non-conductive, it becomes "0"). "RAM" is synonymous with what is well known in the industry, and stores information electrically (for example, when a current for reading data is applied, if the charge is stored, it becomes "1", and if the charge is not stored, it becomes "0". It is generally configured so that a backup power source is supplied to some or all of the data stored in the RAM in the event of a power cut)."Game state" refers to, for example, a special game state in which game medals are easy to obtain and advantageous for the player (so-called big win game, also known as during bonus activation, during type 1 BB activation, at the time of type 1 BB activation, during type 2 BB activation, at the time of type 2 BB activation, etc.), an internal middle state with a carried-over bonus winning (also known as during type 1 BB internal, during type 2 BB internal, etc.), a replay probability variable game state (RT state) in which the winning rate of the replay role is higher (or lower) than that of the normal game state where the winning rate of the replay role is a predetermined value, the stop order and stop position of the reels (also known as stop operation mode) for winning the selected role can be notified during AT (assist time), an ART (assist replay time) state in which the RT state and the AT middle state are combined, an advantageous section where processing related to AT can be executed and a normal section where processing related to AT is not executed, etc. Also, even in the normal game state, there are an RT state, an AT middle state (also known as "AT game state", "AT state", "notification state", and sometimes simply called "AT"), and a state that is not in the AT middle state is also known as "non-AT game state", "non-AT state", "non-notification state", and sometimes simply called "non-AT".) Also, notifying the stop operation mode in the AT state is sometimes called "executing AT", "executing navigation", "executing instructions", "executing push order navigation", "executing notification game", etc. There are a high-probability normal game state, a low-probability normal game state, etc. (in this example, called lottery state) where the transition lottery probability to the ART middle state is different. Also, the game states can be combined without problem {Furthermore, all of these game states and functions (for example, the transition lottery to the AT middle state, the output of notification instructions related to the stop order of the reels, etc.) can be implemented entirely on the main control board side that controls the game progress without problem}. Also, in this example, the state related to AT and the RT state are described separately, and the RT state is called "RT1" and the state related to AT is called "normal game state", etc., but the state related to RT and the state related to AT can also be combined as the state related to ART and the state related to ART can be called "normal game state", etc. "Selected role" refers to the type (or condition device number) of the condition device selected by internal lottery (also known as internal note lottery).The "notification state" is a state regarding the AT that can execute the push order navigation described later. Even in a game where a conditional device that does not execute the push order navigation is selected because the winning combination does not differ depending on the stop order of the reels, if the state regarding the AT is a state where the push order navigation can be executed, it is configured to be the "notification state". The "counter value" is also referred to as the "number of executable notification games", and is the remaining number of AT games or the counter value of the AT counter M60 described later. For example, when the "number of executable notification games" is 1 or more (it may include the game when it becomes "0"), the push order navigation described later can be executed. Also, as the "number of executable notification games", the difference in the number of game media obtained based on the winning of a minor combination (mainly the push order bell combination), or the number of times the push order bell combination is won, may be adopted. The "special notification state" is the most advantageous state for the player among the states regarding the AT. In this example, it is referred to as the "state specialized for additional bonus". The "predetermined game state" may be any one or a combination of one or more of all the states such as the game states and notification states described in this example. The "specific condition" is a condition that can subtract the AT counter value. For example, when one game ends, or a predetermined combination (e.g., the push order bell combination) is won, etc., are specific conditions. The "first type special accessory" is an accessory that increases the number of combinations of symbols related to winning for each specified number, or increases the probability that the conditional device related to winning for each specified number operates. It can operate when predetermined conditions are met and continue to operate until the results of a game not exceeding 12 times are obtained, and may be referred to as RB (Regular Bonus). The "first type special accessory continuous operation device" is a device that can continuously operate the first type special accessory. It operates when a specific combination of symbols is displayed and ends operation when predetermined conditions are met, and may be referred to as BB (Big Bonus) or the first type BB. The "second type special accessory" is an accessory that causes the conditional device related to winning to operate regardless of the result of the combination draw. It operates when predetermined conditions are met and ends operation when the result of one game is obtained, and may be referred to as CB (Challenge Bonus).The "Type 2 Special Feature Continuous Operating Device" is a device that can continuously operate a Type 2 special feature, which operates when a specific combination of symbols is displayed and ends operation when a predetermined condition is met, and may be referred to as MB (Middle Bonus) or Type 2 BB. The "Normal Feature" is a feature that increases the number of combinations of symbols related to winning for each specified number, or increases the probability of the conditional device related to winning for each specified number operating, which operates when a specific combination of symbols is displayed and ends operation when the result of one game is obtained, and may be referred to as SB (Single Bonus). The "All JACIN Type" is a configuration where it is regarded as JACIN when the Type 1 BB feature wins, and is always in RB during the execution of the Type 1 BB. Also, the "JACIN Lottery Type" is a configuration where it repeatedly executes between non-RB and RB during the execution of the Type 1 BB. Also, the "Uncontrolled Reel" is a reel in a state where the retraction control that can be executed after a stop operation is not executed, and is a reel that stops at the nearest reel position where it can stop from the reel position that received the stop operation. The "All CB Type" is a configuration where it is always in CB during the execution of the Type 2 BB. The "CB Transition Lottery Type" is a configuration where it repeatedly executes between non-CB and CB during the execution of the Type 2 BB.

[0009] Note that the following embodiments are merely examples, and are not limited to the following aspects regarding the location and function of each means, the order of each step regarding various processes, the timing of turning flags on and off, the names of the means responsible for the processing of each step, etc. Also, the above-described embodiments and modification examples should not be construed as being limited to being applied to specific ones, and any combination may be used. For example, a modification example for a certain embodiment should be understood as a modification example from another embodiment, and even if a certain modification example and another modification example are described independently, it should be understood that a combination of the said certain modification example and the said another modification example is also described.

[0010] <<<First Embodiment>>> Before explaining each component, the features (outline) of the rotary gaming machine P according to the first embodiment will be described. Hereinafter, each element will be described in detail with reference to the drawings.

[0011] First, with reference to FIG. 1 (FIG. 2 for some configurations), the basic structure on the front side of the rotary gaming machine P according to the first embodiment will be described. The rotary gaming machine P mainly includes a front door (also referred to as a front door), a back box (also referred to as a cabinet or a base), a reel unit installed in the back box, a hopper device, a power supply unit E, a main control board M (a board on which a main control chip C including a CPU MC is mounted), and a sub-control board S (a board on which a sub-control chip SC including a CPU SC is mounted). Hereinafter, these will be described in order.

[0012] <Front Door DU> The front door DU includes a mechanism for visually recognizing the gaming state, a mechanism for enabling the input of gaming media, a mechanism for operating the reel unit, and other mechanisms. Specifically, as a mechanism for visually recognizing the gaming state, a reel window D160, an input number display lamp D210, a start lamp D180, a replay lamp D290, an insertable lamp D300, a special gaming state display device D250, a credit number display device D200, a payout number display device (push order display device) D270 (sometimes referred to as the push order display device D270), an AT counter value display device D280, a favorable section indicator YH, etc. are attached. Also, as a mechanism for enabling the input of gaming media and the bet amount (number of bets), a medal insertion port D170 and a bet button D220 are provided. And as a mechanism for enabling the payout of the inserted gaming media, a settlement button D60 is attached. And as a mechanism for operating the reel, a start lever D50 and a stop button D40 are attached. Note that the rotary gaming machine in the first embodiment is provided with an operation table protruding toward the player side where a start lever D50, a stop button D40, a medal insertion port D170, a bet button D220, a settlement button D60, a sub-input button SB, a cross key SB2, etc. are attached. Hereinafter, each element will be described in detail.

[0013] <Mechanism for making the gaming state visible> Next, the main part of the mechanism for making the game status visible will be described. The reel window D160 is a transparent member made of synthetic resin or the like that constitutes a part of the front door DU, and is configured so that the reel unit installed in the gaming machine frame can be seen through the reel window D160. The insertion number indicator lamp D210 is composed of three LEDs, and is configured so that the same number of LEDs as the number of medals currently bet (the number of medals required to start one game) are lit up. Specifically, the insertion number indicator lamp D210 is composed of three LEDs (lamps): a 1 bet lamp D211, a 2 bet lamp D212, and a 3 bet lamp D213. When one game medal has been bet, the 1 bet lamp D211 is lit, the 2 bet lamp D212 is turned off, and the 3 bet lamp D213 is turned off. When two game medals have been bet, the 1 bet lamp D211 is lit, the 2 bet lamp D212 is lit, and the 3 bet lamp D213 is turned off. When three game medals have been bet, the 1 bet lamp D211 is lit, the 2 bet lamp D212 is lit, and the 3 bet lamp D213 is lit (this does not apply to the next game after the replay has been stopped; details will be described later). The start lamp D180 is made of an LED and is configured to light when the operation of the start lever D50 is valid (operation is accepted) and to turn off when the operation of the start lever D50 is invalid (operation is not accepted). The replay lamp D290 is made of an LED and is configured to light when the replay is stopped and to turn off when the next game after the replay is stopped is completed. The insertion possible lamp D300 is configured to light (or flash) when the insertion of a game medal into the medal insertion slot D170 is valid or the operation of the bet button D220 is valid, and to turn off when the insertion of a game medal is invalid or the operation of the bet button D220 is invalid. The special game state display device D250 is made of a 7-segment display and is configured to display the total number of payouts paid out during the special game.It is also possible to adopt a configuration without providing the special game state display device D250. In such a case, by configuring the effect display device S40 (which may also be referred to as the second information display unit) described later to display the total number of payout counts, the player can recognize the total number of payout counts paid out during the special game, and a user-friendly gaming machine can be achieved. Further, the credit number display device D200 is configured by a 7-segment display and is configured to display the total number of medals (credit number) stored in the gaming machine as the player's held medals. Also, the payout count display device (push order display device) D270 is configured by a 7-segment display, and in a game where a conditional device {which is a so-called push order winning combination (sometimes also referred to as a winning combination with a push order), and in cases where the winning combination or the displayed symbol combination for stopping is different, it is generally configured such that the profit rate (number of payout medals, subsequent RT state, etc.) given to the player can be different} is established, it is configured to be able to notify the player of the most advantageous reel stop order for the player (this notification may be referred to as push order navigation). Thus, the payout count display device (push order display device) D270 is configured to be able to execute two displays, namely the number of gaming medals currently being paid out and the reel stop order that is most profitable for the player, and the display mode is such that the player does not misidentify which of the two displays is being executed. The details of this display mode will be described later.Also, the AT counter value display device D280 can display the number of games that a player can stay in a state advantageous for the player in the AT (details will be described later) among the states related to the AT, which is guaranteed when the game progresses according to the push order navigation display (as described above, notifying the player of an advantageous operation mode (stop operation mode) of the stop button by the push order display device D270 is sometimes referred to as "executing the push order navigation", "executing the AT", "executing the navigation", "executing the instruction", "executing the notification game"). In this example, it is sometimes referred to as the push order navigation state or the notification game, and the details will be described later). Incidentally, it is also possible to adopt a configuration without providing the AT counter value display device D280. In such a case, by configuring the effect display device S40 to display the number of games that can be stayed in the state during the AT, the player can recognize the number of games in which the state advantageous for the player in the AT is guaranteed, and a user-friendly gaming machine can be obtained. Incidentally, the payout number display device (push order display device) D270 may be configured to be divided into two devices, a payout number display device and a push order display device.

[0014] In addition, the advantageous section indicator YH is composed of LEDs and is configured to light up when it is in the "advantageous section" and turn off when it is not in the "advantageous section" (the lighting and extinguishing timings will be described later). Here, in the rotary drum type gaming machine according to this example, similar to the conventional rotary drum type gaming machine, a special gaming state in which game medals are easy to obtain and advantageous for the player (so-called big win gaming, corresponding to bonus gaming, first type BB, second type BB, etc.), a re-game probability variable gaming state (RT state) in which the winning rate of the re-game combination is higher (or lower) than that in the normal gaming state where the winning rate of the re-game combination is a predetermined value, a state during AT (assist time) that can notify the stop order and stop position of the reels for winning the selected combination, an ART (assist replay time) state in which the RT state and the AT state are combined, etc. can be adopted. Apart from these "gaming states", any one of three "gaming sections", namely, the "normal section", the "standby section", and the "advantageous section" can be set. In this example, the "standby section" is not set, and either the "normal section" or the "advantageous section" is set. Among these, the "advantageous section" is positioned as being relatively more advantageous for the player than the other "gaming sections". For example, the "gaming state" being in the AT state or the ART state is associated with the "advantageous section". That is, when the "gaming state" is in the AT state or the ART state, the advantageous section indicator YH lights up. However, as will be described later, the setting control of the "gaming section" is also performed on the main control board side that controls the progress of the game, similar to the setting control of the "gaming state". Therefore, based on the lighting / extinguishing status of the advantageous section indicator YH, it is possible to truthfully convey to the player whether the progress of the game is relatively advantageous for the player or not.As will be described later, when the "advantageous period" continues until a predetermined upper limit number of games (for example, 1500 games) is reached, the "normal period" is forcibly set. At that time, the state regarding the remaining AT is also forcibly terminated (information for maintaining the in-AT state is cleared / initialized). Therefore, the change of the set "game period" can also affect the transition of the "game state", and thereby, it is possible to automatically suppress the significant increase in the probability of winning due to the "game state" such as the in-AT state and the ART state with relatively high design freedom. As described above, when the "advantageous period" continues until a predetermined upper limit number of games (for example, 1500 games) is reached, the "normal period" is forcibly set, that is, the "advantageous period" ends. However, the end condition of the "advantageous period" is not limited to this. The end condition of the "advantageous period" in the spinning reel gaming machine according to this example is that "one execution of the push order navigation that can obtain the minor winning combination with the largest number of payout coins among the minor winning combinations constituting the push order winning combination (for example, when there are minor winning combinations of 7 coins, 3 coins, and 1 coin as the minor winning combinations constituting the push order winning combination, it is the push order navigation that can obtain the 7 coins with the largest number of payout coins. If there are push order winning combinations that can obtain 7 coins or 1 coin according to the push order and a push order winning combination that can obtain 3 coins according to the push order, the push order navigation that can obtain 3 coins does not correspond to the push order navigation referred to here)", or satisfies "winning any one of BB, RB, MB", and, "any end condition (non-winning in the loop lottery of 40G1 set (AT), passing of fixed 32G (precursor of gas), etc.)", or "advantageous period of 1500G" is the end condition. Note that in the case of a specification where there is no push order bell winning combination (for example, a specification where there is a push order for replay to shift to the RT state, but there are no minor winning combinations with different payout coin numbers according to the push order), the condition for ending the "advantageous period" of "one execution of the push order navigation that can obtain the minor winning combination with the largest number of payout coins" is excluded. Also, in the first embodiment, since the minor winning combinations constituting the push order winning combination include a minor winning combination corresponding to an 11-coin winning combination and a minor winning combination corresponding to a 1-coin winning combination, "one execution of the push order navigation that can obtain the minor winning combination with the largest number of payout coins" refers to notifying the push order that can obtain 11 medals (the 11-coin winning combination is winning).

[0015] <Mechanism for enabling input of gaming media> Next, the main part of the mechanism for enabling input of gaming media will be described. The medal insertion slot D170 is an insertion slot for gaming medals, and the gaming medals inserted into the slot are guided into the gaming machine under the condition of being in a medal acceptance-enabled state. Also, inside the gaming machine, as sensors for detecting medal insertion, an insertion acceptance sensor D10s, a first insertion sensor D20s, and a second insertion sensor D30s are provided, and when it is determined that the gaming medals guided into the gaming machine have been normally inserted, they are configured to be able to detect the inserted medals as bet medals. Also, the bet button D220 is configured to be operable by the player, and by the operation, the stored medals (credit medals) can be bet. Also, the settlement button D60 is configured to be operable by the player, and by the operation, the stored medals (credit medals) and / or the bet medals can be returned to the player. Note that the gaming medals returned by the operation of the settlement button D60 are configured to be paid out through the payout port D240.

[0016] <Mechanism for operating the reel unit> Next, the start lever D50 is configured to be operable by the player, and by the operation, the operation of the reel can be started. Also, the stop buttons D40 include a left stop button D41, a middle stop button D42, and a right stop button D43 that are operable by the player, and by operating each stop button, the operation of the reel can be sequentially stopped.

[0017] <Other mechanisms provided on the front door DU> Next, with reference to the perspective view showing the internal configuration of the rotary gaming machine P with the front door DU of FIG. 2 opened, the main parts of the other mechanisms provided in the front door DU will be described. On the front door DU, as a mechanism for enhancing the amusement of the game, there are provided an effect display device S40 for displaying effects such as a pre-announcement effect and a background effect, a game effect lamp D26 (not shown) that can be lit in various lighting modes, a door substrate D for signal relay, a medal selector DS for detecting the inserted medals, etc., a speaker S20 that can output sound, a middle panel (middle decorative panel), an upper panel D130, and a lower panel D140, etc., which are members formed of synthetic resin or the like. The effect display device S40 is attached to the upper part on the back side of the front door DU so that the display part for displaying effects and the like can be visually recognized through the perspective area formed in the upper panel. Also, the decoration lamp unit D150 and the LED lamp unit S10 have light sources that emit light according to the progress of the game of the rotary gaming machine P. The decoration lamp unit D150 is provided on each of the right and left sides with the lower panel D140 interposed therebetween, and the LED lamp unit S10 is provided on each of the right and left sides with the upper panel D130 interposed therebetween (the decoration lamp unit D150 and the LED lamp unit S10 may be collectively referred to as the lamp unit). Also, below the reel window D160 on the back of the front door DU, the door substrate D is attached. Input signals such as the aforementioned stop button D40, start lever D50, settlement button D60, etc. are input to this door substrate D, and it has the function of a relay substrate that directly or processes the input signals and outputs them to the main control substrate M described later. Also, corresponding to the medal insertion slot D170, a medal selector DS, which will be described in detail later, is provided near the door substrate D on the back of the front door DU. It has the function of detecting the medals inserted from the medal insertion slot D170, performing a simple authenticity check, guiding the appropriate medals to the hopper H40 described later, and returning the inappropriate medals to the medal tray D230 described later. Further, one speaker S20 is provided on each of the left and right sides below the door substrate D. The middle panel is the upper part of the operation table and the lower part of the upper panel D130, and is the panel part including the aforementioned reel window.The sub-input button SB and cross key SB2 attached to the operation console D190 are members used for operation on a menu screen described later, button rapid-fire effects on the sub-control board S (successfully pressing the sub-input button SB to execute effects related to whether or not a bonus has been won), and mini-games (for example, effects related to the success or failure of entering an "AT state"), etc. The front door DU of the slot machine P is provided with a medal tray D230 for receiving game medals (or simply medals) discharged from the discharge port D240, and a door switch D80 capable of detecting the open / closed state of the front door DU. The front door DU is provided with a keyhole D260, and is configured to be able to open the front door DU by inserting a key (door key) that matches the shape of the keyhole D260 into the keyhole D260 {and twisting it in a predetermined direction (for example, clockwise)}. Furthermore, in the first embodiment, an error state (such as a door opening error) can be released by inserting the door key into the keyhole D260 {and twisting it in a predetermined direction (for example, counterclockwise)}. A bet button lamp S50 is provided inside the bet button D220, and the bet button lamp S50 is composed of an LED controlled by the sub-control board S. When the bet button lamp S50 lights up (or blinks), the player can perceive that the operation of the bet button D220 is valid. A stop button lamp S60 is provided inside the stop button D40 (provided for each of the three stop buttons, the left stop button D41, the center stop button D42, and the right stop button D43). The stop button lamp S60 is composed of an LED controlled by the sub-control board S, and when the stop button lamp S60 lights up (or blinks) and / or when the stop button lamp S60 lights up (or blinks), the player can perceive that the operation of the stop button D40 is valid.Since only the stop button lamp S60 corresponding to the valid stop button D40 lights up in the lighting color corresponding to the valid stop button D40, for example, when the left stop button D41 is invalid, the middle stop button D42 is valid, and the right stop button D43 is valid, the stop button lamp S60 corresponding to the left stop button D41 turns off, the stop button lamp S60 corresponding to the middle stop button D42 lights up, and the stop button lamp S60 corresponding to the right stop button D43 lights up. Thus, the lighting modes of the three stop button lamps S60 are configured to be different from each other. Also, by making the lighting color and lighting mode of the stop button lamp S60 different (it may be made different like lighting · flashing, or different like slow flashing · fast flashing), in a game where the push order navigation is executed, it may be configured to make it easier for the player to distinguish the stop button that should be operated currently. For example, when all the reels are rotating and the player wins the push order bell where the push order of "left → middle → right" is the correct answer (the maximum number of payout coins), the stop button lamp corresponding to the left stop button blinks in white, and the stop button lamps corresponding to the middle stop button and the right stop button light up in blue. Then, when the player operates the left stop button to stop the left reel, the stop button lamp corresponding to the left stop button turns off, the stop button lamp corresponding to the middle stop button blinks in white, and the stop button lamp corresponding to the right stop button lights up in blue.

[0018] Next, the back box (also referred to as the cabinet or base) and each device installed inside the back box will be described. A reel unit is attached at approximately the center of the back box so that a part of it can be viewed through the reel window D160. The reel unit includes a reel M50 and a drive source (such as a stepping motor) for the reel M50. Further, the reel M50 includes a left reel M51, a middle reel M52, and a right reel M53. Here, each reel part is formed of synthetic resin or the like, and a plurality of patterns are drawn on the outer periphery of the reel part (on the reel tape MO). And based on the operation of each stop button in the start lever D50 and the stop button D40, it is configured to enable the rotation operation and stop operation of each reel part. Also, although not shown, LEDs (hereinafter sometimes referred to as reel backlights) are provided inside the left reel M51, the middle reel M52, and the right reel M53, and when the LEDs are lit, it is configured to be visible as if the outer periphery of the reel part is lit by the light transmitted through the outer periphery of the reel part. Further, above the reel M50, a turning board K (described later) for driving each reel (left reel M51, middle reel M52, right reel M53) is stored.

[0019] Also, above the reel M50, a main control board M (described later) that controls the entire game is stored, and to the left of the reel M50, a sub-control board S (described later) that controls various effects performed using the effect display device S40, LED lamp unit S10, speaker S20, etc. shown in FIG. 1 is stored. Note that a setting key switch M20 used to execute the setting change device control process (to make a setting change) and a setting / reset button M30 that can execute changes in setting values, error cancellation, etc. are connected to the main control board M. In FIG. 2, the setting key switch M20 and the setting / reset button M30 are not shown, but they may be provided at appropriate positions on the board of the main control board M (that is, at a position where it is difficult for artificial access without opening the front door DU).

[0020] Below the reel M50, there are provided a hopper H40 for collecting the inserted game medals and a medal payout device H for paying out the game medals, and a power supply board E for supplying power to the entire rotary gaming machine P is stored. The game medals paid out from the medal payout device H pass through the coin shooter D90 and are paid out from the discharge port D240. Also, a power switch E10 for turning on the power of the rotary gaming machine P is provided on the front surface of the power supply board E (which may also be referred to as the power supply unit E). The details of the medal payout device H will be described later.

[0021] <Medal selector DS> Next, the medal selector DS will be described in detail with reference to FIG. 3. FIG. 3 is a perspective view showing the path (selector) of the game medals inserted into the medal insertion slot D170 inside the rotary gaming machine P. The medal selector DS is provided with an insertion reception sensor D10s that serves as a passage for the game medals inserted from the medal insertion slot D170 near the door substrate D. Below the insertion reception sensor D10s, a coin shooter D90 and the like for guiding the game medals to the discharge port D240 are provided. The insertion reception sensor D10s mainly selects the game medals inserted from the medal insertion slot D170 based on their dimensions and has the function of accepting only the game medals that conform to the standard dimensions. Medals (or other foreign objects) determined not to conform by this function are configured to be returned to the discharge port D240 by the blocker D100. When a game medal is inserted before the player operates the start lever D50 (when the insertion of game medals is valid), the game medal is selected by the insertion reception sensor D10s, and only those that meet the standard are inserted into the hopper H40, while the medals that do not meet the standard are returned to the discharge port D240 through the coin shooter D90. On the other hand, when a game medal is inserted after the start lever D50 is operated (when the insertion of game medals is not valid), regardless of whether it meets the standard or not, the inserted game medal is returned to the discharge port D240 through the coin shooter D90. Also, inside the insertion reception sensor D10s (at the back of the flow path), a sensor related to medal insertion, which will be described in detail later, is provided. When the game medal that has been accepted while meeting the dimension standard passes through, it is detected by the first insertion sensor D20s and the second insertion sensor D30s, and the signal is supplied to the main control board M described later.

[0022] Next, the sensor related to medal insertion will be described in detail. The game medals inserted into the medal insertion port D170 first pass through the insertion reception sensor D10s. The insertion reception sensor D10s is a mechanical double sensor. When the game medal passes through, two protruding mechanisms are pressed down, turning it on, allowing the game medal to pass through the passage normally. Also, with such a configuration, when a foreign object that is not a game medal (a foreign object that does not meet the specifications, for example, one with a smaller diameter than the game medal) is inserted, the two protruding mechanisms are not pressed down. Such a medal cannot maintain an upright state, so it cannot pass through the passage (the medal falls over) and is returned to the discharge port D240 through the coin shooter D90 as described above. In addition, the insertion reception sensor D10s is configured to be able to determine an error even when the time it is on continues for a predetermined time or more (as a result, the blocker D100 can be turned off).

[0023] When the game medal passes through the blocker D100 normally, it will pass through the first insertion sensor D20s and the second insertion sensor D30s immediately after passing. This insertion sensor (the first insertion sensor D20s and the second insertion sensor D30s) is composed of two sensors (adjacent to each other at an interval smaller than the standard diameter of the game medal), and various errors can be detected by monitoring the on / off status (the transition order of the on / off combinations of the first insertion sensor D20s and the second insertion sensor D30s, etc.) and the on / off time of each sensor.

[0024] <Medal payout device H> Next, the medal payout device H will be described in detail with reference to the front view and top view of the medal payout device H in FIG. 4. The medal payout device H will operate when the settlement button is operated in a state where there are credits (game medals electronically stored inside the gaming machine) or bet medals (medals inserted to start the game), or when game medals are paid out due to a winning. When operating, first, the hopper motor H80 is driven, causing the disk H50 to rotate around the disk rotation shaft H50a. Due to the rotation, the game medals inside the medal payout device H displace the discharge biasing means H70 and flow down from the game medal outlet H60 toward the discharge port D240. Note that the payout sensors (the first payout sensor H10s and the second payout sensor H20s) are composed of two sensors, and various errors can be detected by monitoring the on / off status (the transition order of the on / off combinations of the first payout sensor H10s and the second payout sensor H20s, etc.) and the on / off time of each sensor. More specifically, for example, when passing through the game medal outlet H60 normally, due to the displacement of the discharge biasing means H70, the sensor state transitions from the state of the first payout sensor H10s = off · the second payout sensor H20s = off to the first payout sensor H10s = off · the second payout sensor H20s = off → the first payout sensor H10s = on · the second payout sensor H20s = off → the first payout sensor H10s = on · the second payout sensor H20s = on → the first payout sensor H10s = off · the second payout sensor H20s = on → the first payout sensor H10s = off · the second payout sensor H20s = off. Therefore, it can be exemplified that when a movement contrary to this sensor state transition is detected, it is configured to be an error.

[0025] Next, FIG. 5 shows a list of the basic specifications of the rotary gaming machine in the first embodiment. The rotary gaming machine according to the first embodiment has a specified number (the maximum number of game medals that can be bet in one game) of 3, and the number of reels of the left reel M51, the middle reel M52, and the right reel M53 is all 20, and the effective line for prize winning determination is one line of "the upper stage of the left reel M51, the middle stage of the middle reel M52, and the lower stage of the right reel M53". Incidentally, the maximum payout number of medals is 11, and the minimum payout number of medals is 1 (the correspondence between the winning combination and the payout number of medals will be described later). Also, the priority winning order (drawing priority order) is "re-play game winning combination → small winning combination (bell, watermelon, etc.) → bonus". For example, when both the re-play game winning combination and the bonus are established at the same time, the symbol combination that becomes the re-play game winning combination stops displaying and the bonus cannot be won. Also, when the bell and the watermelon are established, if the stop button is pressed at a position where both can be drawn (a position within 4 reels from the winning stop position), the small winning combination with a larger payout number of medals is preferentially drawn. Incidentally, the configuration shown in the figure is merely an example, and there is no problem in changing the number of reels of each reel (for example, changing to 21 reels) or changing the configuration of the effective lines (for example, changing to 5 lines of 3 horizontal lines and 2 diagonal lines, or changing to one line of the lower stage of the left reel M51, the middle stage of the middle reel M52, and the upper stage of the right reel M53). Also, as the drawing control when a small winning combination with a different benefit for the player depending on the pressing order is won, when operated in the predetermined correct pressing order, it is controlled to preferentially draw the small winning combination with a larger payout number of medals (number priority control), and when operated in an incorrect pressing order different from the correct pressing order, control is performed to draw the symbol that increases the winning possibility (the symbol with the most winning possibilities among the plurality of symbol combinations that can win) among the symbols that can be stopped and displayed (arranged within 4 reels from the stop operation) (number of symbols priority control).

[0026] Next, FIG. 6 shows a list of reel arrangements of the rotary gaming machine in the first embodiment. As shown in the figure, the number of frames of the left reel M51, the middle reel M52, and the right reel M53 is all 20 frames (from frame 0 to frame 19), and the symbols are 10 types: "Black Seven", "White Seven", "Sheep", "Blank", "Bell", "Replay A", "Replay B", "Watermelon A", "Watermelon B", and "Cherry". Here, "Blank" is a symbol included in the symbol combinations that form winning combinations, just like other symbols. It does not mean a symbol that does not form a winning combination. For example, as a symbol combination that forms a winning combination including "Blank", "Watermelon B·Replay A·Blank" is the replay 02. Note that the configuration shown in the figure is just an example, and there is no problem in increasing, decreasing, or changing the types of symbols.

[0027] Next, FIGS. 7 to 9 are lists 1 to 3 of symbol combinations in the first embodiment. In the first embodiment, there are a plurality of symbol combinations for each condition device. As will be described later, depending on the stop order and stop positions of the left reel M51, the middle reel M52, and the right reel M53, any one of the symbol combinations is configured to be stopped and displayed on the effective line (the aforementioned one line). In addition, even when the same type of symbols are not aligned on the effective line, it is configured such that it is easy for the same symbols to be aligned in a row on a line other than the effective line when viewed by the player (in the case of a watermelon, three watermelon symbols are aligned in a horizontal straight line in the middle row, etc., and are configured to be aligned in a straight line on any of the reels). Further, in the first embodiment, as symbol combinations that result in the first type of BB combination (which is a combination of continuous operation devices related to the so-called first type of special combination, hereinafter sometimes simply referred to as the BB combination), there are "sheep · sheep · sheep" which results in the first type of BB-A (continuously operating RB-A and ending with a payout exceeding 264 pieces), "black seven · black seven · black seven" which results in the first type of BB-B (continuously operating RB-B and ending with a payout exceeding 132 pieces), and "white seven · white seven · white seven" which results in the first type of BB-C (continuously operating RB-B and ending with a payout exceeding 132 pieces). In addition, in the first embodiment, when the first type of BB combination wins and the BB is executed (the combination operates), during the execution of the BB, in all games during the BB, it is configured to draw non-combination winning combinations (minor combinations, replay combinations) by referring to one lottery table (it is a method of not switching the table referred to during combination drawing during the execution of one BB, hereinafter sometimes referred to as the all-JACIN type). Regarding the form of the first type of BB combination, it is not limited to this, and it may be configured such that the table referred to during combination drawing during the execution of one BB can be switched. Also, when a symbol combination corresponding to replay 04 for positions 14 to 16 is stopped and displayed when the RT state is "RT1", it is configured to shift to RT0 (details of the RT state will be described later). Since the RT state of "RT0" is more disadvantageous to the player than "RT1", shifting from "RT1" to "RT0" may be referred to as a fall.Also, when the symbol combination corresponding to No. 17 and serving as replay game 05 stops being displayed, "Black Seven" may stop being displayed in the lower part of the left reel M51, the middle reel M52, and the right reel M53. When the symbol combination corresponding to No. 18 and serving as replay game 05 stops being displayed, "White Seven" may stop being displayed in the lower part of the left reel M51, the middle reel M52, and the right reel M53 (details will be described later). Further, when the push-order bell, which is a conditional device for "Prize - A1" to "Prize - A6" described later, wins, if the reels are stopped in the most advantageous push order for the player, the symbol combinations corresponding to Nos. 21 to 27 and serving as "Prize 01" to "Prize 03" will stop being displayed, and 11 game medals will be paid out. On the other hand, if the reels are stopped in a push order different from the most advantageous push order for the player, the symbol combinations corresponding to Nos. 39 to 56 and serving as "Prize 08" to "Prize 11" will stop being displayed, and 1 game medal will be paid out. Incidentally, the "-" in the figure indicates that any symbol may stop being displayed. For example, for "Bell · - · Bell" corresponding to No. 23, if Bell stops being displayed on the effective lines of the left reel M51 and the right reel M53, 11 game medals can be obtained regardless of which symbol stops being displayed on the effective line of the middle reel M52.

[0028] Next, FIG. 10 shows a list of conditional devices in the first embodiment. In this figure, the conditional device number is referred to as the winning number, and the conditional device number may also be referred to as the winning number hereinafter. In the first embodiment, replay winning roles are provided up to Replay-A to Replay-D3 (winning numbers 1 to 6), and depending on the stop order and stop position of the left reel M51, middle reel M52, and right reel M53, the replay winning role to be stopped and displayed can be different. Here, in the first embodiment, as shown in the item of "Conditional Device" in the rightmost column, a plurality of types of conditional devices can be stopped and displayed according to the stop order and stop position of the left reel M51, middle reel M52, and right reel M53. The conditional devices with the same winning number among the plurality of types of conditional devices are grouped together and shown in the item of "Conditional Device (Name)" in the third column from the right. Specifically, for example, in "Replay-A", which is the conditional device corresponding to the winning number 1, three types of conditional devices, namely "Replay 01", "Replay 02", and "Replay 03", can be stopped and displayed according to the stop order and stop position of the left reel M51, middle reel M52, and right reel M53. Note that "Conditional Device (Name)" may be simply referred to as a conditional device. Also, a conditional device related to a replay such as "Replay 01" may be referred to as a replay winning role, a conditional device that pays out game medals by winning such as "Winning 01" may be referred to as a minor winning role, and a conditional device that starts BB when it is stopped and displayed such as "1 Type BB-A" may be referred to as a BB winning role. Also, when winning numbers 21 to 23 and 25 to 27 are won, the BB winning role and the minor winning role overlap and are won. In such a case, when the left stop button D41, middle stop button D42, and right stop button D43 are operated at a position where the symbol corresponding to the won minor winning role can be stopped and displayed, the symbol corresponding to the BB winning role is not stopped and displayed, and the symbol corresponding to the minor winning role is stopped and displayed. On the other hand, when the left stop button D41, middle stop button D42, and right stop button D43 are operated at a position where the symbol corresponding to the minor winning role cannot be stopped and displayed (pulled in), the symbol corresponding to the minor winning role is not stopped and displayed, and the symbol corresponding to the BB winning role is stopped and displayed.Specifically, for example, when winning the "1 type BB-B + winning - C", which is the winning number 21's conditional device, either the cherry that is "winning 12" or "winning 13", or the black seven that is "1 type BB-B" may stop and be displayed. More specifically, when stopping the reels in the order of the left reel M51 → the middle reel M52 → the right reel M53, (1) When the left stop button D41 is operated at the operation timing when the symbol numbers 0 to 4 (refer to the reel arrangement in FIG. 6) are located in the upper stage of the left reel M51 at the first stop, the symbol number 4 corresponding to "winning 12" stops in the upper stage of the left reel M51, and regardless of the stop positions of the middle reel M52 and the right reel M53, "winning 12" is stopped and displayed. (2) When the left stop button D41 is operated at the operation timing when the symbol numbers 5 to 12 are located in the upper stage of the left reel M51 at the first stop, the symbol numbers 6, 11, or 16 corresponding to "winning 13" stop in the upper stage of the left reel M51, and regardless of the stop positions of the middle reel M52 and the right reel M53, "winning 13" is stopped and displayed. (3-1) When the left stop button D41 is operated at the operation timing when the symbol numbers 13 to 19 are located in the upper stage of the left reel M51 at the first stop, the symbol number 17 or 19 corresponding to "1 type BB-B" stops in the upper stage of the left reel M51. (3-2) When the middle stop button D42 is operated at the operation timing when the symbol numbers 14 to 18 are located in the middle stage of the middle reel M52 at the second stop, the symbol number 18 corresponding to "1 type BB-B" stops in the middle stage of the middle reel M52. Then, when the right stop button D43 is operated at the operation timing when the symbol numbers 13 to 17 are located in the lower stage of the right reel M53 at the third stop, the symbol number 17 corresponding to "1 type BB-B" stops in the lower stage of the right reel M53, and the BB combination will be stopped and displayed. (3-3) When the middle stop button D42 is operated at the operation timing when the symbol numbers 19 to 13 are located in the middle stage of the middle reel M52 at the second stop, the symbol number 18 corresponding to "1 type BB-B" cannot stop in the middle stage of the middle reel M52, and none of the conditional devices will be stopped and displayed.

[0029] Next, in the "Role" item, it illustrates what role the "Condition Device (Name)" plays. The "Normal Replay" corresponding to Winning Number 1 is a condition device related to a replay in which a replay role where the RT state does not transition is stopped and displayed regardless of the pressing order of the stop button. The "Reverse Push White Seven Aligned Replay" corresponding to Winning Number 2 is also a condition device related to a replay in which a replay role where the RT state does not transition is stopped and displayed regardless of the pressing order of the stop button. However, in the case of reverse push (stopping the reels in the order of the right reel M53 → middle reel M52 → left reel M51), by operating the stop button at the operation timing when the symbol number ranges of 18 to 2 of the right reel M53, 9 to 13 of the middle reel M52, and 5 to 10 of the left reel M51 are located at the lower stage of each reel, "White Seven" is stopped and displayed at the lower stage of the right reel M53, middle reel M52, and left reel M51, and is configured to look as if White Seven is aligned at the lower stage as seen by the player. In addition, in a game where Replay - B is won and the AT bonus lottery is won, by executing an effect (details will be described later) that instructs to aim for "White Seven" by reverse push, it is configured to be able to notify the player that they have won the AT bonus lottery. The "Forward Push Black Seven Aligned Replay" corresponding to Winning Number 3 is a condition device related to a replay in which a replay role where the RT state does not transition is stopped and displayed regardless of the pressing order of the stop button. However, in the case of forward push (stopping the reels in the order of the left reel M51 → middle reel M52 → right reel M53), by operating the stop button at the operation timing when the symbol number ranges of 13 to 19 of the left reel M51, 14 to 18 of the middle reel M52, and 13 to 17 of the right reel M53 are located at the lower stage of each reel, "Black Seven" is stopped and displayed at the lower stage of the left reel M51, middle reel M52, and right reel M53, and is configured to look as if Black Seven is aligned at the lower stage as seen by the player. In addition, in a game where Replay - C is won and the AT bonus lottery is won, by executing an effect (details will be described later) that instructs to aim for "Black Seven" by forward push, it is configured to be able to notify the player that they have won the AT bonus lottery.

[0030] Also, the "RT maintenance RP1** (3 selections)" corresponding to the winning number 4 is a conditional device in which the re-game role to be stopped and displayed may differ depending on which of the first stop reels is the left reel M51, the middle reel M52, or the right reel M53 (which stop button is operated). When the first stop reel is the left reel M51, re-game 01, re-game 02, or re-game 03 in which the RT state does not transition is stopped and displayed. When the first stop reel is the middle reel M52 or the right reel M53, re-game 04 in which the RT state can transition from "RT1" to "RT0" is stopped and displayed. Also, the "RT maintenance RP*1* (3 selections)" corresponding to the winning number 5 is a conditional device in which the re-game role to be stopped and displayed may differ depending on which of the first stop reels is the left reel M51, the middle reel M52, or the right reel M53 (which stop button is operated). When the first stop reel is the middle reel M52, re-game 03 in which the RT state does not transition is stopped and displayed. When the first stop reel is the left reel M51 or the right reel M53, re-game 04 in which the RT state can transition from "RT1" to "RT0" is stopped and displayed. Also, the "RT maintenance RP**1 (3 selections)" corresponding to the winning number 6 is a conditional device in which the re-game role to be stopped and displayed may differ depending on which of the first stop reels is the left reel M51, the middle reel M52, or the right reel M53 (which stop button is operated). When the first stop reel is the right reel M53, re-game 01 or re-game 03 in which the RT state does not transition is stopped and displayed. When the first stop reel is the left reel M51 or the middle reel M52, re-game 04 in which the RT state can transition from "RT1" to "RT0" is stopped and displayed.

[0031] In addition, the "Push Order Bell 123" to "Push Order Bell 321" corresponding to the winning numbers 7 to 12 are conditional devices where the winning minor combinations can differ depending on which of the six options the reel stop order is set to. For example, it is set as "Left Reel M51: 1, Middle Reel M52: 2, Right Reel M53: 3", and in the case of "123", it means to stop in the push order of "Left Reel M51 → Middle Reel M52 → Right Reel M53". For example, in the case of "Winning - A1" (winning number 7), when it stops in the order of "123" = "Left → Middle → Right" (correct push order), a symbol combination of "Winning 01" will be stopped and displayed, where the maximum number of game medals that can be obtained, which is 11, can be obtained. Note that "123" in "Push Order Bell 123", etc., indicates the push order (reel stop order) that can obtain the maximum number of winning medals for that winning number. Note that when the reels are stopped in a push order other than the push order that can obtain the maximum number of winning medals, that is, if the push order cannot be guessed correctly, it is configured to pay out 1 medal. By configuring it in this way, in the state related to AT such as the "During AT state", the push order of the replay combination and the push order of the bell are navigated (the push order that gives the highest profit is displayed on the push order display device D270), and multiple game states with different player profit rates can be created, where the push order is not navigated in the state related to AT such as the "Normal Game State". The state related to AT will be described later.

[0032] In addition, the "Common Bell" corresponding to the winning number 13 is a conditional device that can obtain 11 game medals, which is the maximum number of medals that can be obtained regardless of which of the winning numbers 04 to 07 stops, that is, a conditional device that can obtain the maximum profit regardless of the pressing order, and is sometimes referred to as a bell regardless of the pressing order. Also, the "Watermelon A" corresponding to the winning number 15 is configured such that it is easy for three watermelons (either Watermelon A or Watermelon B) to line up in parallel lines. For example, in the winning combination 14 at position 60 in FIG. 9, three Watermelon As line up in the middle of each reel. Further, the "Watermelon B" corresponding to the winning number 16 is configured such that it is easy for three watermelons (either Watermelon A or Watermelon B) to line up in diagonal lines. For example, in the winning combination 16 at position 66 in FIG. 9, three watermelons line up diagonally downward, with Watermelon B at the upper part of the left reel M51, Watermelon B in the middle of the middle reel M52, and Watermelon A at the lower part of the right reel M53. Also, the "BB Medium Weak Rare Minor Combination (Diagonal Bell Alignment)" corresponding to the winning number 17 is a conditional device in which three bells can line up on the effective line. Although the details will be described later, it is a conditional device in which an AT additional lottery is executed by winning during BB. Further, the "BB Medium Strong Rare Minor Combination (V-Shaped Bell Alignment)" corresponding to the winning number 18 is a conditional device in which bells can stop and be displayed at the upper part of the left reel M51, the middle of the middle reel M52, and the upper part of the right reel M53. Although the details will be described later, it is a conditional device in which an AT additional lottery is executed by winning during BB.

[0033] Next, in the item of "Bonus Winning Information", numerical values from 0 to 3 are allocated for each winning number. In the first embodiment, the winning numbers that do not include a bonus (BB combination) have a bonus winning information of 0, and as the winning numbers that include a bonus (BB combination), the bonus winning information of the winning number (19) that includes one type of BB-A is 1, the bonus winning information of the winning numbers (20 to 23) that include one type of BB-B is 2, and the bonus winning information of the winning numbers (24 to 27) that include one type of BB-C is 3. By the main control board M storing the bonus winning information, information regarding the presence or absence of any BB establishment and which BB combination was won can be stored. Note that the details of the bonus winning information will be described later.

[0034] Next, in the item of "winning and replay winning information", numerical values from 0 to 18 are allocated for each winning number. In the first embodiment, for the winning numbers that do not include replay roles and minor roles (the winning number 0 corresponding to a loss and the winning numbers 19, 20, and 24 corresponding to bonuses), the winning and replay winning information is set to 0, and for the winning numbers that include replay roles or minor roles, the winning and replay winning information from 1 to 18 is allocated for each conditional device. By the main control board M storing the winning and replay winning information, information regarding which replay role or minor role has been won can be stored. Note that details of the winning and replay winning information will be described later.

[0035] Next, in the item of "production group number", numerical values from 0 to 11 are allocated for each winning number. By transmitting the production group number from the main control board M side to the sub-control board S side, the sub-control board S side is configured to be able to determine the production to be executed. Note that details of the production group number will be described later.

[0036] Next, in the item of "payout ball group number", numerical values from 0 to 13 are allocated for each winning number. The main control board M stores the payout ball group number, and by using the stored payout ball group number when executing a lottery related to AT (for example, an AT lottery, an AT additional lottery), the program and data capacity for executing the lottery process related to AT can be reduced. Note that even if a conditional device with a payout ball group number of 0 wins, the AT lottery and the AT additional lottery are not executed. On the other hand, when a conditional device with a non-zero payout ball group number wins, the AT lottery or the AT additional lottery may be executed. Note that details of the payout ball group number will be described later. Also, even when a conditional device with a payout ball group number of 0 wins, it may be configured such that the AT lottery or the AT additional lottery can be executed. In such a configuration, when a conditional device with a payout ball group number of 0 wins and the AT lottery or the AT additional lottery is executed, it is preferable to configure the lottery result to always be a loss (non-winning).

[0037] Next, FIG. 11 is a list showing the winning numbers (also referred to as conditional device numbers and winning roles) and bonuses (also referred to as BB and BB roles) for minor roles and replay roles in the first embodiment, and the lottery probabilities (also referred to as winning rates and winning probabilities) determined by the role lottery means. In this figure, the winning rates of the winning numbers are illustrated.

[0038] First, the lottery probabilities in "RT0", "RT1", and "RT2" when BB is not activated will be described in detail. In the first embodiment, the appearance rate (lottery probability) of winning roles (especially replay roles) can differ depending on the RT state. The "replay role" (the total appearance rate of all replay roles) has a higher appearance rate in the case of "RT1" than in other RT states. Also, "Replay 04" which can stop and be displayed at winning numbers 4 to 6 (a so-called falling replay role, which is "RT1" and when the symbol combination corresponding to the replay role stops and is displayed in a situation where no bonus has been won, it will subsequently shift to "RT0") mainly wins in "RT1" and hardly appears in "RT0". Incidentally, in "RT2", "Replay 04" which can stop and be displayed at winning numbers 4 to 6 can appear, but the RT state does not shift even if "Replay 04" stops and is displayed. Incidentally, when "Replay 04" stops and is displayed in "RT1", a falling effect (for example, displaying "What a pity" on the effect display device S40), which is an effect for notifying that the RT state has fallen, i.e., has shifted to "RT0", is executed. When "Replay 04" stops and is displayed in "RT0", it may be configured not to execute the falling effect. By configuring it in this way, even though "Replay 04" has stopped and been displayed, since the falling effect is not executed, it is possible to recognize that a BB has been won, and the interest of the game can be enhanced. Incidentally, when configured in this way, the effect sound output when "Replay 04" stops and is displayed may be different from the effect sound output when a replay role other than "Replay 04" (for example, "Replay 01" where the RT state does not shift) stops and is displayed. By configuring it in this way, it is possible to make it easier for the player to recognize that "Replay 04" has stopped and been displayed. Also, in both cases, when it is in a state related to AT where no push-order navigation occurs (for example, "normal game state", which may be referred to as a non-AT game state) and when it is in a state related to AT where push-order navigation can occur (for example, "during AT state", which may be referred to as an AT game state), it may stay in "RT1".At this time, when a winning number that may shift (fall) from "RT1" to "RT0" is won, it may be configured not to output a special effect sound indicating that the RT state may fall in the non-AT game state based on the operation of the start lever D50. As a result, in the non-AT game state, it becomes possible to shift the game state without making the player aware that there is a possibility of falling to "RT0". On the other hand, in the AT game state, it may be configured to output a special effect sound indicating that the RT state may fall based on the operation of the start lever (and notify a push order navigator in which a replay winning combination that does not cause the RT state to fall is stopped and displayed). As a result, the player can be careful not to let the RT state fall and can operate the stop button D40 after the special effect sound is notified. Also, "Replay 05" (a replay winning combination that can notify that it has won the AT additional lottery when stopped and displayed in the AT state), which can be stopped and displayed with winning numbers 2 or 3, mainly appears in "RT1" and hardly appears in other RT states. Incidentally, the state transition regarding the RT state associated with the stop display of the symbol combinations that become these replay winning combinations will be described later. Also, as will be described later, in the first embodiment, it is configured such that a push order navigator that notifies the reel stop order most advantageous to the player can be executed by the push order display device D270 and the effect display device S40. Incidentally, there is no problem in appropriately changing the lottery probability. Also, in the first embodiment, the bonus is configured to be able to overlap with small winning combinations and overlaps with a part of watermelon A, watermelon B, and cherry. Specifically, winning numbers 21 to 23 and winning numbers 25 to 27 are conditional devices in which the bonus and small winning combinations overlap.

[0039] Also, in the situation of "RT2", since BB is elected and BB is not activated, when winning the BB roles of winning numbers 20 and 24 (which are single BB roles not overlapping with minor roles and may be referred to as single BB roles or single BB), the new winning of the BB role becomes invalid, and only the winning of the minor role is valid. Specifically, for example, in the situation of "RT2" and having won (carried over) one type of BB-A, when winning "one type of BB-C" of winning number 24, the one type of BB-C related to winning number 24 becomes invalid. That is, it is the same situation as when winning "losing" of winning number 0. Still, the carried-over one type of BB-A remains in the winning state. Also, in the situation of "RT2", since BB is elected and BB is not activated, when winning the conditional device where the minor roles of winning numbers 21 to 23 and winning numbers 25 to 27 overlap with the BB role, the new winning of the BB role becomes invalid, and only the winning of the minor role is valid. Specifically, for example, in the situation of "RT2" and having won (carried over) one type of BB-A, when winning "one type of BB-B + winning -C" of winning number 21, the one type of BB-B related to winning number 21 becomes invalid, and only winning -C is valid. That is, it is the same situation as when winning "winning -C" of winning number 14. Still, the carried-over one type of BB-A remains in the winning state. Still, the overlap with the bonus is not limited to minor roles and may also overlap with a part of the replay role. For example, it may overlap with a part of the replay role of winning numbers 4 to 6 and the bonus role. In this way, by making the bonus also overlap with the conditional device including the RT transition replay (replay role where the RT state can transition), there is a possibility of winning the bonus even when the conditional device including the RT transition replay is won. Even if the RT transition replay stops being displayed, the bonus will not be negated, so it is possible to give the player expectations. In addition, when configured in this way, control is performed so that the RT state does not transition even if the RT transition replay stops being displayed.As a result, since the player should be in the RT state (transitioning to the RT state with a relatively low replay probability), but the replay probability is not low (winning the replay frequently), etc., it becomes possible to increase the player's interest in the game, such as the possibility of winning a bonus being high.

[0040] Next, the lottery probabilities in the "Type 1 BB-A, B, C" when the BB is activated will be described in detail. In the first embodiment, during the activation of the BB, three small roles, namely the "Common Bell" of winning number 13, the "Weak Rare Small Role during BB (Diagonal Bell Alignment)" of winning number 17, and the "Strong Rare Small Role during BB (V-shaped Bell Alignment)" of winning number 18, are configured to be able to win. During the activation of the BB that won in the "AT Middle State", when winning the "Weak Rare Small Role during BB (Diagonal Bell Alignment)" or the "Strong Rare Small Role during BB (V-shaped Bell Alignment)", an AT bonus lottery is configured to be executed (details will be described later).

[0041] In addition, in the upper part of the figure, the appearance rate of small roles when the set value is 1 is illustrated. In the common bell (winning number 13), the appearance rate is uniform regardless of the RT state. However, as shown in the lower part of the figure, the appearance rate of the common bell is configured to vary depending on the set value (in this example, there are six levels). Specifically, the number of placements in setting 1 is 3204, the number of placements in setting 2 is 3404, the number of placements in setting 3 is 3604, the number of placements in setting 4 is 3904, the number of placements in setting 5 is 4204, and the number of placements in setting 6 is 4504. The configuration is such that the appearance rate increases as the set value increases. By configuring it in this way, for example, when a player progresses the game while measuring the number of appearances (winning times) of the common bell, the player can progress the game while expecting that the set value related to the gaming machine being played is a relatively high set value due to frequent wins of the common bell. Also, the expected value per game increases as the set value increases, and the payout rate increases as the set value increases. Although the appearance rate of the common bell is configured to vary depending on the set value, the AT lottery, AT bonus lottery, and high-probability state transition lottery described later are not executed depending on the win of the common bell, so it is configured not to affect the transition lottery of the state related to AT (also referred to as the lottery related to AT).

[0042] Also, the middle part of the figure shows a list of expected values when there is a push order navigation. In this figure, when the push order navigation is executed in a state where the push order navigation can be executed by the push order display device D270 and the effect display device S40 such as the "AT in progress state", the average payout per game when the reels are stopped according to the navigation (the average number of medals paid out by the winning minor combinations, which is also referred to as the expected number of game media obtained in one game), and the medal increase / decrease expected value per game (the ratio of the number of medals paid out to the number of medals bet in a game with 3 bets. When it is greater than 1, the expected value is positive and the medals increase, while when it is less than 1, the expected value is negative and the medals decrease) are illustrated. Note that the average payout per game can be calculated as "the sum of the number of placements of the replay combination (the sum of the number of placements for winning numbers 1 to 6) × the number of payout medals in the replay combination (3 medals) + the sum of the number of placements of the minor combination (11 - medal combination) (the appearance rate of the minor combination) (the sum of the number of placements for winning numbers 7 to 16) × the number of payout medals in the minor combination (11 medals) / the total number of all placements (65536)". Also, the medal increase / decrease expected value per game can be calculated as "the average payout per game / the number of medals bet per game (3 medals)". Note that the number of medals bet per game (the number of game media input when playing one game) is 3, and when the average payout per game is greater than 3, the medal increase / decrease expected value per game is configured to be greater than 1. As shown in this figure, in the first embodiment, "RT1" has the relatively largest medal increase / decrease expected value per game. Note that the numerical values in this figure do not consider the increase or decrease of medals due to bonuses. That is, when the game progresses in a situation where the push order navigation occurs (also referred to as when it is operated in the optimal operation mode or the advantageous operation mode), the medals will increase in "RT1". Note that in "RT0" and "RT2", although not shown, in a situation where the push order navigation does not occur, the medal increase / decrease expected value per game is less than 1, and the medals will decrease.In the first embodiment, even when there is a push order navigation in "RT0" or "RT2", the medal increase / decrease expected value per game is greater than 1, but it is not limited thereto, and it may be configured such that the medal increase / decrease expected value per game when there is a push order navigation in "RT0" or "RT2" is less than 1. When the symbol combination that becomes a replay winning combination stops displaying, actually, the number of bet medals in the previous game (3 medals) is automatically bet, but when calculating the medal increase / decrease expected value in the first embodiment, it is calculated assuming the payout of 3 medals. Note that one game may be referred to as one play.

[0043] Also, the average number of payouts per game in each RT state is 3.511291504 when the RT state is "RT0", 4.737915039 when the RT state is "RT1", and 3.67137146 when the RT state is "RT2". Also, the expected value of medal increase or decrease per game in each RT state is 1.170430501 when the RT state is "RT0", 1.579305013 when the RT state is "RT1", and 1.223790487 when the RT state is "RT2". When there is a push order navigator, the RT state of "RT1" is the most advantageous RT state for the player. Note that the said numerical values are the values in the case of setting 1. Note that the winning numbers and the lottery probabilities of the bonuses for the above-mentioned minor winning combinations and replay winning combinations are merely examples. For example, the expected value of medal increase or decrease per game (the expected value of medal increase or decrease when there is a push order navigator) in "RT2" when BB is internally established may be configured to be less than 1. By configuring it in this way, even when the player fails to align the bonuses in a game where the bonuses can be aligned in a situation where a push order navigator occurs and the state is "RT2" (when BB is internally established), the player's held medals will gradually decrease. Also, in a situation where a push order navigator occurs and the state is "RT2" (when BB is internally established), it is possible to prevent strategies such as increasing the held medals by deliberately not aligning the bonuses in a game where the bonuses can be aligned. Specifically, it is preferable to design the probability of losing in "RT2" to be higher than the winning probabilities of all minor winning combinations (winning - A1 to winning - I) that win in "RT2", and it is preferable to determine the winning probability of the replay winning combination so that it is designed in this way (if the winning probability of the replay winning combination is designed to be high, the probability of losing will be low accordingly, so it is preferable to design so that the winning probability of the replay winning combination does not become too high). Note that in "RT2" of this example, the total winning probability of all minor winning combinations is 18784 / 65536, the total winning probability of all replays is 12501 / 65536, and the probability of losing is 34251 / 65536 (see Figure 11), and it is designed so that the probability of losing is higher than the total winning probability of all minor winning combinations.

[0044] Also, as shown in FIG. 11, in the first embodiment, for all of settings 1 to 6, the appearance rate of one type of BB-A has 40, which is the same number of allocations. Also, for all of settings 1 to 6, the appearance rate of one type of BB-C has 160, which is the same number of allocations. In contrast, for setting 1, the appearance rate of one type of BB-B has 160 allocated, for setting 2, 180 is allocated, for setting 3, 200 is allocated, for setting 4, 220 is allocated, for setting 5, 240 is allocated, and for setting 6, 270 is allocated. That is, the appearance rate of one type of BB-B has different numbers of allocations depending on the setting value. Thus, one type of BB-A and one type of BB-C function as BBs without a setting difference (one type of BB-A and one type of BB-C may be referred to as BBs without a setting difference and bonuses without a setting difference), and one type of BB-B functions as a BB with a setting difference (one type of BB-B may be referred to as a BB with a setting difference and a bonus with a setting difference). Also, for any of one type of BB-A, one type of BB-B, and one type of BB-C, the appearance rate is uniform regardless of the RT state (between "RT0" and "RT1"). Incidentally, the appearance rate of one type of BB-A and one type of BB-C (total) is the same regardless of the setting value, but the appearance rate of one type of BB-B (total) differs depending on the setting value. Incidentally, the total appearance rate as the appearance rate of one type of BB-B is the same even if the setting values are different, but it may be configured such that the appearance rate for each winning number differs depending on the setting value, and even in such a configuration, one type of BB-B may be referred to as a BB with a setting difference.

[0045] Next, while referring to the block diagram of FIG. 12, the electrical schematic configuration of the rotary gaming machine P according to the first embodiment will be described. First, the rotary gaming machine according to the first embodiment is configured such that a sub-control board S, a door board D, a rotary board K, a power supply board E, a relay board IN, a setting key switch M20, a setting / reset button M30, etc. are connected so as to be able to exchange data, with the main control board M that controls the progress of the game at the center. Note that the solid lines in the figure indicate the movement related to data exchange, and the broken lines in the figure indicate the power supply route. Note that the power supply route is not limited to this, and for example, power may be supplied from the power supply board E to the relay board IN or the door board D without passing through the main control board.

[0046] The main control board (which may be referred to as the main control means, the main board, the main gaming unit, etc.) M is a board that controls the progress of the entire game played on the rotary gaming machine P. The main control board M is equipped with a main control chip C, and the main control chip C has a CPU C100 (which may also be referred to as CPU MC), a built-in ROM C110, a built-in RAM C120, etc. connected to each other via a bus so as to be able to exchange data. Then, the main control board M receives signals indicating that the start lever D50, etc. has been operated from the door board D mounted on the front door DU, and outputs control commands (or control signals) to the sub-control board S, the door board D, the rotary board K, etc., thereby controlling the operations of these various boards {for example, by outputting an instruction number (also referred to as a pressing order number, instruction information, operation information) to the sub-control board S, the sub-control board S can execute a pressing order navigation on the effect display device S40}.

[0047] Also, on the sub-control board (which may also be referred to as the sub-control means, sub-board, sub-control means, sub-board, or sub-game unit) S, similar to the main control board M described above, a sub-control chip SC is mounted. The sub-control chip SC is provided with a CPUSC100, a ROM, a RAM, etc., and is configured to be connected to each other so that data can be exchanged via a bus. Further, various LED lamps S10 (including the bet button lamp S50 and the stop button lamp S60), a speaker S20, an effect display device S40, a reel backlight (also referred to as a back lamp) S30, etc. are connected to the sub-control board S. Here, the reel backlight S30 is a light provided inside each of the left reel M51, the middle reel M52, and the right reel M53, and illuminates the pattern drawn on the surface of the reel from the back side. The sub-control board S analyzes the control commands received from the main control board M and outputs drive signals to various LED lamps S10, the speaker S20, the effect display device S40, the reel backlight S30, etc., respectively, to perform various effects. In the rotary gaming machine according to this example, a plurality of LEDs are provided as the reel backlight S30 so that the player can individually identify the nine ranges of the upper, middle, and lower stages of the left reel, the upper, middle, and lower stages of the middle reel, and the upper, middle, and lower stages of the right reel. As an example, when the LED corresponding to the upper stage of the left reel lights up and all other LEDs are turned off, the player can identify that the upper stage of the left reel is lit. Further, the rotary gaming machine according to this example is configured to be capable of executing a backlight effect (which may also be referred to as a back lamp effect) that suggests to the player that the predetermined symbol combination has stopped being displayed by changing the lighting mode of the reel backlight S30 when the predetermined symbol combination stops being displayed.

[0048] On the door substrate D, there are the above-mentioned input reception sensor D10s, first input sensor D20s, second input sensor D30s, stop button D40 for stopping the rotating reel M50, start lever D50 for starting the rotation of the reel M50, settlement button D60 for paying out the stored game medals (credits) or the inserted game medals to end the game, various display panels D70 for displaying the game state {although not shown in the figure, the above-mentioned input number display lamp D210, start lamp D180, replay lamp D290, insertable lamp D300, special game state display device D250, payout number display device (push order display device) D270 are an aggregate of display devices such as credit number display device D200, favorable section indicator YH, etc.}, door switch D80 for performing opening / closing determination of the front door, error cancellation, and setting value change, blocker D100 for paying back the game medals (or other foreign objects) determined not to be suitable after being inserted to the discharge port D240, etc. are connected. Further, this door substrate D is connected to be able to exchange data with the above-mentioned main control substrate M. For this reason, when operating the start lever D50, stop button D40, settlement button D60, etc. provided on the front door DU, a signal related to the operation is supplied to the main control substrate M via the door substrate D. Also, a signal detected by the input reception sensor D10s detecting the passage of the game medal is also supplied to the main control substrate M via the door substrate D.

[0049] In addition, a drum motor K10 for rotating the reel M50, a drum sensor K20 for detecting the rotational position of the reel M50, etc. are connected to the drum substrate K. The drum substrate K can stop the reel M50 at a determined stop position by driving the drum motor K10 while detecting the rotational position of the reel M50 with the drum sensor K20. In the drum-type gaming machine of the first embodiment, a so-called step motor (sometimes referred to as a stepping motor) is used for the drum motor K10. Incidentally, 480 steps are set as the number of steps for one rotation of the reel M50 by the step motor. Also, a predetermined number (for example, 20) of symbols of substantially uniform size are set on each reel (left reel M51, middle reel M52, right reel M53), and 24 steps (= 480 / 20) are set as the number of steps corresponding to one symbol. Incidentally, there is no problem even if the number of steps and the number of symbols per reel are changed.

[0050] In addition, the medal payout device H is connected to the main control board M via the relay board IN, and performs an operation of paying out a predetermined number (for example, 10) of game medals based on a control signal from the main control board M. Incidentally, the medal payout device H is connected to a first payout sensor H10s and a second payout sensor H20s that execute determination of whether medals are normally paid out and measurement of the number of game medals paid out, and a hopper motor H80 for rotating the disk H50.

[0051] The power consumed by these various control boards and the boards is supplied from a power supply board E (a board that controls the presence or absence of power supply by a power switch E10). In FIG. 12, the state of power being supplied from the power supply board E is represented by a dashed arrow. As shown in the figure, power is directly supplied from the power supply board E to the main control board M and the sub-control board S, and power is supplied to various boards (door board D, drum board K, relay board IN) via the main control board M. A predetermined amount (for example, 100V) of AC voltage is supplied to the power supply board E, and after converting this power into a DC voltage of a specified voltage, it is supplied to each control board and board.

[0052] Also, connected to the main control board M are a setting key switch M20 used for executing a setting change device control process (for making a setting change) described later, and a setting / reset button M30 capable of executing changes in set values, error cancellation, etc. Further, the main control board M includes a reel control means for controlling the rotation and stop of reels M50 (left reel M51, middle reel M52, right reel M53), an AT lottery means for executing an AT transition lottery for transitioning to an "AT in progress state", which is a state advantageous to the player regarding AT, and an AT bonus lottery means for executing an AT bonus lottery for increasing the number of games remaining in AT (or the counter value of the AT counter M60), which is the number of games that can stay in the "AT in progress state".

[0053] Next, FIGS. 13 to 36 are flowcharts showing the flow of general processing performed by the main control board M in the first embodiment.

[0054] Note that the flowchart is mainly composed of processing steps (illustrated as rectangles), judgments (illustrated as diamonds), flow lines (arrows), and terminals (illustrated as rounded rectangles) indicating start, end, return, etc. Also, among the processing steps, if details are illustrated in another flowchart, the reference to that other flowchart is illustrated as a subroutine (a rectangle with double lines on the left and right). Here, in the development stage of the gaming machine, gaming machines with different specifications are sometimes developed simultaneously, but in this example, the configuration is such that no subroutines (usually unused subroutines) for gaming machines with different specifications are left in the main-side processing, preventing the execution of processing related to unused subroutines that are not normally executed due to noise or improper behavior.

[0055] First, FIG. 13 is a flowchart showing the flow of processing that is first executed by the CPU C100 of the main control board M after the power of the rotary gaming machine P is turned on (or at the time of system reset or user reset). First, at step 1000, after the power of the rotary gaming machine P is turned on, at step 1002, the CPU C100 of the main control board M executes initial setting of timer interrupts (here, not starting the timer interrupt but only setting the type of timer interrupt, and in subsequent processing, when the timer interrupt is started, the flowchart related to the timer interrupt processing described later is periodically executed). Next, at step 1004, the CPU C100 of the main control board M executes settings for serial communication (settings such as speed, data length, data transmission method) as function settings of the main control chip C. Next, at step 1006, the CPU C100 of the main control board M calculates a checksum from the start address of the RAM area to the address immediately before the checksum area. Next, at step 1008, the CPU C100 of the main control board M checks the RAM area (for example, based on the calculated checksum and the checksum data held in the checksum area, checks whether the data stored in the built-in RAM C120 is correctly held due to power-off and power-on recovery), and generates power-on recovery data. Next, at step 1010, the CPU C100 of the main control board M checks the switch state of the setting key switch M20. Next, at step 1014, the CPU C100 of the main control board M determines whether the setting key switch M20 is off.

[0056] If the answer is Yes in step 1014, in step 1016, the CPU C100 of the main control board M refers to the on / off state of the power-off processed flag in the RAM (which is turned on in step 1904) and the checksum state of all the RAM (the check result in step 1006), and determines whether the power-off return data in the RAM is normal. If the answer is Yes in step 1016, in step 1020, the CPU C100 of the main control board M executes the initialization of the RAM area within the determined initialization range. Next, in step 1022, the CPU C100 of the main control board M restores the stack pointer based on the data related to the stack pointer saved during the power-off process (step 1902). Next, in step 1036, the CPU C100 of the main control board M refers to the RAM area and determines whether the data related to the set value in the RAM area is within the normal range (in this example, 0 to 5). If the answer is Yes in step 1036, in step 1038, the CPU C100 of the main control board M reads the input port. Next, in step 1040, the CPU C100 of the main control board M starts the timer interrupt set in step 1002. Next, in step 1042, the CPU C100 of the main control board M turns off the power-off processed flag and returns to the power-off process according to the restored stack pointer.

[0057] Also, if the answer is No in step 1016, in step 1024, the CPU C100 of the main control board M sets the backup error display (for example, sets the error number in the register area). Next, in step 1300, the CPU C100 of the main control board M executes the non-recoverable error process described later.

[0058] Also, if the answer is No in step 1036, in step 1046, the CPU C100 of the main control board M sets the set value error display (for example, it will be displayed on the payout number display device D270) (for example, sets it in the register area). Next, in step 1300, the CPU C100 of the main control board M executes the non-recoverable error process described later.

[0059] Also, when the answer is No in step 1014, in step 1028, the CPU C100 of the main control board M refers to the on / off state of the power-off processing completed flag in the RAM (which is turned on in step 1904) and the checksum state of the entire RAM (the check result in step 1006), and determines whether the power-off return data in the RAM is normal. When the answer is Yes in step 1028, in step 1030, the CPU C100 of the main control board M determines and sets the initialization range of the RAM to a predetermined range excluding the storage area that stores the set values (set value data) in the RAM (for example, set within the register area), and proceeds to step 1034. The range not included in the initialization range of the RAM is not limited to only the storage area that stores the set values (set value data), and the total cumulative number of games in the "advantage section", the total cumulative number of games in the game section (advantage section + normal section), the result of calculating the occupancy ratio in the "advantage section", etc. are also in the range not included in the initialization range of the RAM. By configuring in this way, it becomes possible to calculate and display the ratio (advantage section ratio) of staying in the "advantage section" in the game. Also, the calculation process of the advantage section ratio is configured to be calculated at the timing when a unit game ends. Also, the advantage section ratio is displayed when the power of the gaming machine is turned on (for example, displayed on a 4-digit 7-segment display). As a specific display mode, it is repeatedly displayed at 5-second intervals in the order of "advantage section ratio → continuous accessory ratio per 6000 games → accessory ratio per 6000 games → cumulative continuous accessory ratio → cumulative accessory ratio". Note that the continuous accessory ratio is "number of payouts in the state where RB is operating / total number of payouts", and the accessory ratio is "number of payouts in the state where RB, CB, or SB is operating / total number of payouts". On the other hand, when the answer is No in step 1028, in step 1032, the CPU C100 of the main control board M determines and sets the initialization range of the RAM to a specific range including the storage area that stores the set values (set value data) in the RAM (for example, set within the register area), and proceeds to step 1034. Next, in step 1034, the CPU C100 of the main control board M executes the initialization of the RAM area within the initialization range determined in step 1030 or step 1032.Next, in step 1100, the CPU C100 of the main control board M executes the setting change device control process, which will be described later.

[0060] Although not shown, it is preferable that the initial value (the value at the start of processing) of the temporary storage area (such as the RAM area) mounted on the main control board M is configured not to be a value for which a special game is executed (to prevent a special game from being erroneously executed in the event that a process for determining the execution of a special game is executed due to noise or improper conduct immediately after the start of program processing). Also, although not shown, when storing a random number such as a winning random number in the RAM area of the main control board M, it is preferable to secure a dedicated storage area and store only the information related to the random number in the byte storing the information related to the random number (without storing other information such as various timer values) (to prevent the information related to the random number from being rewritten due to noise or the like when operating other data stored in the same byte).

[0061] Next, FIG. 14 is a flowchart of the setting change device control process related to the subroutine of step 1100 in FIG. 13, which is also referred to as the setting change mode. First, in step 1102, the CPU C100 of the main control board M sets the stack pointer (initializes it with the start address of the process). Next, in step 1104, the CPU C100 of the main control board M activates the timer interrupt. Next, in step 1106, the CPU C100 of the main control board M determines whether the set value (set value data) in the RAM area is within the normal range (in this example, 0 to 5). Incidentally, when the set value (set value data) was managed from 1 to 6, it was necessary to execute the initialization of the RAM and return the set value to "1" when it became "0". Therefore, in this example, by managing the normal range of the set value (set value data) as 0 to 5, it is possible to eliminate the correction process (the processes of steps 1106 and 1108) of the set value (set value data) after executing the RAM initialization, and it becomes possible to shorten the processing time and reduce the processing capacity. If Yes in step 1106, in step 1108, the CPU C100 of the main control board M sets a predetermined value (for example, 0 = the value most disadvantageous to the player) to the set value (set value data), and proceeds to step 1110. On the other hand, even if No in step 1106, it proceeds to step 1110. Next, in step 1110, the CPU C100 of the main control board M displays on the error display LED (for example, the payout number display device D270) that the setting change device is in operation (for example, "88" that lights up all segments), and displays the set value on the setting display LED (not shown) (the display related to the set value is a numerical value obtained by adding 1 to the set value (set value data) held in the RAM), and proceeds to step 1112. Incidentally, as described above, the payout number display device D270 is also used when notifying the pressing order. Since it is configured in such a way, for example, when notifying the pressing order in a case where a part of the 7-segment LED has a failure (there is a segment that cannot light up), incorrect information may be notified.To prevent such a situation, during the operation of the setting change device, by causing all seven segments of the payout number display device D270 to light up as "88", it is possible to check whether the seven segments are malfunctioning and prevent giving disadvantages to the player. Also, as a configuration related to the display of the set value (set value data), it may have a storage area of a RAM for set value display that stores data obtained by adding 1 to the set value (set value data) in the storage area that stores the set value, and may be configured to display the set value by referring to the storage area. Although not shown, after executing the process of step 1110, a process for transmitting a command indicating that the setting change mode has been entered is executed on the sub-control board S side.

[0062] Next, in step 1112, the CPU C100 of the main control board M determines whether the setting / reset button M30 has switched from off to on. If Yes in step 1112, in step 1114, the CPU C100 of the main control board M adds 1 to the current set value (set value data) (if the resulting set value (set value data) exceeds 5, the set value (set value data) becomes 0), and proceeds to step 1116. Also, even if No in step 1112, it proceeds to step 1116. Next, in step 1116, the CPU C100 of the main control board M determines whether the start lever D50 has switched from off to on. If No in step 1116, it proceeds to step 1112, and the processes of steps 1112 to 1116 are looped. If Yes in step 1116, in step 1118, the CPU C100 of the main control board M determines whether the setting key switch M20 has switched from on to off. If No in step 1118, the process of step 1118 is looped. On the other hand, if Yes in step 1118, in step 1120, the CPU C100 of the main control board M displays that the operation of the setting change device has ended on the error display LED (not shown), erases the display of the set value (set value data) of the setting display LED (not shown), and proceeds to the game progress control process of step 1200. Although not shown, after executing the process of step 1120, a process for transmitting a command indicating the end of the setting change mode is executed on the sub-control board S side.

[0063] Next, FIG. 15 is a flowchart of non-returnable error handling related to the subroutine in step 1300 in FIG. 13 (and called in other flowcharts). First, in step 1302, the CPU C100 of the main control board M prohibits interrupts (hereinafter, the flowchart related to the timer interrupt handling described later will not be executed). Next, in step 1304, the CPU C100 of the main control board M sets the output port address and the number of output ports. Next, in step 1306, the CPU C100 of the main control board M turns off the output ports (in this example, 0 to 6, which are display outputs to various LEDs and drive outputs to various motors). Next, in step 1308, the CPU C100 of the main control board M sets the next port output address (by this repetition, the display outputs to various LEDs and the drive outputs to various motors are sequentially stopped). Next, in step 1310, the CPU C100 of the main control board M determines whether the output to each output port has ended. If Yes in step 1310, then in step 1312, the CPU C100 of the main control board M executes the set error display (some error has occurred when this process is executed), repeats the execution of the process, and ends when a reset signal is input due to a decrease in the power supply voltage. (That is, it enters an infinite loop and does not accept any operation to prompt a return). Incidentally, if No in step 1310, the process proceeds to step 1306. Incidentally, the processes from step 1306 to step 1310 are processes for clearing the outputs to the LEDs and motors (however, since the external output signal is not cleared, it is possible to output information related to the error and the game progress status at the time of error occurrence to the hall computer side).

[0064] Next, FIG. 16 is a flowchart of the game progress control process (first sheet) related to the subroutine of step 1200 in FIG. 14. First, at step 1202, the CPU C100 of the main control board M sets the stack pointer (initializes it with the start address of the process). Next, at step 1203, the CPU C100 of the main control board M sets the data within the RAM area required for the game (for example, the bet upper limit number, the winning active lines, etc.). Note that step 1203 also includes a process of setting data (data of "0" for clearing the RAM address) for clearing the data used in the previous game {for example, the condition device number (winning number), the effect group number, the instruction information}. Note that the condition device number, the effect group number, the instruction information, etc. may be configured to be overwritten with the numbers selected when the next game is executed without being cleared. Next, at step 1204, the CPU C100 of the main control board M sets the RT state in the game (for example, "RT0", etc.) (sets the RT state determined at step 1704 in FIG. 27). Next, at step 1205, the CPU C100 of the main control board M sets a command related to the RT state set at step 1204 (command to the sub side). Note that the process of setting the RT state may be executed at step 1704 in FIG. 27. Also, a command related to the RT state (command to the sub side) may be set at step 1704. Also, when transmitting the RT state to the sub side, it is not necessary to transmit it constantly, and it may be configured to transmit the RT state to the sub side only when the game section is the "advantage section". Next, at step 1206, the CPU C100 of the main control board M sets the state related to AT in the game (for example, "in-AT state", etc.) (sets the state related to AT determined at steps 1420, 1429 in FIG. 21, steps 1435, 1439, 1443 in FIG. 22, steps 1444-3, 1444-4 in FIG. 23). Next, at step 1207, the CPU C100 of the main control board M sets a command related to the state related to AT set at step 1206 (command to the sub side).Also, the process of setting the state regarding the AT may be executed in step 1416, step 1428 of FIG. 21, step 1438 of FIG. 22, and step 1444-1 of FIG. 23. Also, when transmitting the state regarding the AT to the sub-side, it is not necessary to transmit it constantly, and it may be configured to transmit the state regarding the AT to the sub-side only when the game section is the "advantageous section". Next, in step 1208, the CPU C100 of the main control board M sets the game section (for example, the "advantageous section", etc.) in the game (sets the game section determined in step 3510, step 3516, and step 3520 of FIG. 31). Next, in step 1208-1, the CPU C100 of the main control board M sets a command (command to the sub-side) regarding the game section set in step 1208. Next, in step 1209, the CPU C100 of the main control board M determines whether the medal payout device H is full of game medals or not. Specifically, it is provided with a medal auxiliary tank HS (details will be described later) for storing the medals overflowing from the medal payout device H, and it is determined by the conduction / non-conduction of the current by two full cup detection electrodes DE (details will be described later) that can penetrate inside the medal auxiliary tank HS (when the current conducts through the medals, it is determined to be full). If it is Yes in step 1209, it proceeds to step 1218.

[0065] On the other hand, if the answer is No in step 1209, in step 1210, the CPU C100 of the main control board M turns on the medal full error flag (for example, updates the value corresponding to turning on within the medal full error flag area in the RAM area). Next, in step 1212, the CPU C100 of the main control board M displays the error number corresponding to the medal full error on the 7-segment LED (for example, the stored display LED or the acquired number LED). Next, in step 1214, the CPU C100 of the main control board M determines whether the medal full error has been cleared (for example, whether the current between the two full detection electrodes provided in the medal auxiliary tank HS is non-conductive and whether the setting / reset button M30 has been pressed). If the answer is Yes in step 1214, in step 1216, the CPU C100 of the main control board M turns off the medal full error flag (for example, updates the value corresponding to turning off within the medal full error flag area in the RAM area) and proceeds to step 1218. On the other hand, if the answer is No in step 1214, the process proceeds to step 1212. Next, in step 1218, the CPU C100 of the main control board M permits medal insertion (in the next game of the replay winning combination, the insertion operation will be automatically executed) and proceeds to the next process (the process of step 1220). Here, in step 1218, the on-process of the blocker D100 (the process of forming the medal flow path) is performed. Specifically, if the replay winning combination was established in the previous game, the on-process of the blocker D100 is executed on the condition that the current stored number (credit) is less than a predetermined value (in this example, 50 pieces). In other words, if the current stored number (credit) is the predetermined value, the on-process of the blocker D100 is not executed. On the other hand, if the replay winning combination was not established in the previous game, the on-process of the blocker D100 is uniformly executed.With such a configuration, even when a replay winning combination is formed and the stored number (credit) has not reached a predetermined value, the game medals can be inserted, and when staying in an RT state (e.g., "RT1") with a higher winning probability of the replay winning combination than an RT state such as "RT1", or even when a replay winning combination that is difficult to recognize as a replay winning combination visually (a replay disguised as a small winning combination: a pattern combination such as bell-bell-bell on the invalid line or a cherry stopped on the left reel) stops, the player can play the game rhythmically (without discomfort).

[0066] Next, FIG. 17 is a flowchart of the game progress control process (second sheet) related to the subroutine of step 1200 in FIG. 16. First, at step 1220, the CPU C100 of the main control board M determines whether or not game medals have not been bet or stored (there is no credit). If Yes at step 1220, then at step 1221, the CPU C100 of the main control board M determines whether or not the set value display condition is satisfied (for example, when the door switch D80 and the setting key switch M20 are all turned on, the condition is satisfied). If Yes at step 1221, then at step 1222, the CPU C100 of the main control board M displays the set value on the set display LED (not shown, but may be the payout number display device D270, the credit number display device D200, the inserted number display lamp D210, etc.) (shifts to the setting confirmation mode), and shifts to step 1221 on the condition that the setting key switch M20 is turned off. Incidentally, when the condition for shifting to the setting change mode is satisfied, a process for transmitting a command indicating the start of the setting change mode to the sub-control board S side and a process for transmitting a command indicating the end of the setting change mode when the end condition of the setting change mode is satisfied are executed. If No at step 1220 or step 1221, then at step 1224, the CPU C100 of the main control board M executes management related to the insertion and settlement of game medals. Next, at step 1225, the CPU C100 of the main control board M checks the acceptable number of game medals. Next, at step 1226, the CPU C100 of the main control board M determines whether or not the blocker D100 is on. If Yes at step 1226, then at step 1227, the CPU C100 of the main control board M determines whether or not the first insertion sensor D20s or the second insertion sensor D30s is on (in the first embodiment, there are two insertion sensors for detecting the insertion of medals, and when the first insertion sensor D20s or the second insertion sensor D30s is turned on, it is determined that one game medal has been received).If the answer is Yes in step 1227, then in step 1230, the CPU C100 of the main control board M determines whether the first insertion sensor D20s and the second insertion sensor D30s are off (after the first insertion sensor D20s or the second insertion sensor D30s turns on, if the first insertion sensor D20s and the second insertion sensor D30s turn off, it is determined that the received one game medal has passed through the first insertion sensor D20s and the second insertion sensor D30s). If the answer is Yes in step 1230, then in step 1231, the CPU C100 of the main control board M determines that it has received the insertion of one normal game medal. Although not shown in the figure, after step 1231, the CPU C100 of the main control board M determines whether the credit is at the upper limit number (in this example, 50) and the bet number is at the maximum number (in this example, 3). If the determination is Yes, it controls the blocker D100 to be off (a state where the medal flow path is not formed). If the answer is No in step 1230, the process of step 1230 is repeated. If the answer is No in step 1226 or step 1227, the process proceeds to step 1232.

[0067] Next, in step 1232, the CPU C100 of the main control board M determines whether there has been an operation of the settlement button D60. If Yes in step 1232, in step 1233, the CPU C100 of the main control board M determines whether there are any remaining credit medals or bet game medals. If Yes in step 1233, in step 1234, the CPU C100 of the main control board M turns on the hopper drive flag (a flag in the RAM area that is turned on when driving the hopper motor H80) and executes the payout of one game medal. Next, in step 1236, the CPU C100 of the main control board M determines whether the first payout sensor H10s or the second payout sensor H20s is on (in the first embodiment, there are two payout sensors for detecting the payout of medals, and when the first payout sensor H10s or the second payout sensor H20s is on, it is determined that the payout operation of one game medal is being performed). If Yes in step 1236, the process proceeds to step 1247. Here, although not specified on the flowchart, if the previous game was a replay winning combination, only the remaining number of credits is subject to settlement.

[0068] On the other hand, if the answer is No in step 1236, in step 1241, the CPU C100 of the main control board M determines whether or not a predetermined time (e.g., 5 seconds) has elapsed since after the hopper was driven (after the timing of the process in step 1234). Specifically, it determines whether or not a situation where, despite sending a hopper drive signal to the hopper motor H80 (the hopper motor H80 is rotating), it is determined that no medal has been paid out has continued for a predetermined time. If the answer is Yes in step 1241, in step 1242, the CPU C100 of the main control board M turns on the medal empty error flag (e.g., updates the area within the medal empty error flag region with a value corresponding to being on). Next, in step 1244, the CPU C100 of the main control board M executes a medal empty error display. Next, in step 1245, the CPU C100 of the main control board M determines whether or not the medal empty error has been cleared (e.g., whether or not the setting / reset button M30 has been pressed). If the answer is Yes in step 1245, in step 1246, the CPU C100 of the main control board M turns off the medal empty error flag (e.g., updates the area within the medal empty error flag region in the RAM area with a value corresponding to being off) and proceeds to step 1247. On the other hand, if the answer is No in step 1245, it proceeds to step 1244.

[0069] Next, in step 1247, the CPU C100 of the main control board M determines whether or not the first payout sensor H10s and the second payout sensor H20s are off (after the first payout sensor H10s or the second payout sensor H20s turns on, when the first payout sensor H10s and the second payout sensor H20s turn off, it is determined that the payout operation of one game medal for which the payout operation was being performed has been completed). If the answer is Yes in step 1247, in step 1248, the CPU C100 of the main control board M turns off the hopper drive flag and proceeds to step 1233. Incidentally, if the answer is No in step 1241 or step 1247, it proceeds to step 1236.

[0070] If the answer is "No" in step 1232 or step 1233, in step 1251, the CPU C100 of the main control board M determines whether the start lever D50 is valid (for example, a specified number of game medals for starting the game have been inserted, etc.) and whether there has been an operation of the start lever D50. If the answer is "Yes" in step 1251, in step 1253, the CPU C100 of the main control board M determines whether the set value in the RAM area is within the normal range (in this example, 0 to 5). If the answer is "Yes" in step 1253, in step 1254, after the CPU C100 of the main control board M executes the process of obtaining a random number and turning off the blocker D100, it proceeds to the next process (the process of step 3600). On the other hand, if the answer is "No" in step 1253, in step 1256, the CPU C100 of the main control board M sets a set value error display (for example, sets an error number in the register area). Next, in step 1300, the CPU C100 of the main control board M executes an irrecoverable error process. If the answer is "No" in step 1251, the process proceeds to step 1220.

[0071] Next, FIG. 18 is a flowchart of the game progress control process (third) related to the subroutine of step 1200 in FIG. 16. First, at step 3600, the CPU C100 of the main control board M executes an internal lottery execution process, which will be described later. Next, at step 1259, the CPU C100 of the main control board M determines whether the state regarding the current AT is a state where an AT topping-up lottery can be executed. Here, in this example, the states regarding the AT for which the AT topping-up lottery can be executed are the "during-AT state", the "topping-up specialization state", the "specialization precursor state", and the "advantageous BB state". In the "advantageous BB internal game", the AT counter value can be greater than 0, but the AT topping-up lottery is configured not to be executed. This is to prevent the situation where it is more advantageous for the player not to deliberately align the BB symbol combinations in the "advantageous BB internal game". Note that it may be configured such that the AT topping-up lottery can be executed in the "advantageous BB internal game". In such a case, when winning the AT topping-up lottery in the "advantageous BB internal game", it may not be notified immediately, but instead, it may be configured to notify the fact of winning the AT topping-up lottery at the timing when BB ends later, or the remaining number of AT games after the number of AT games has been topped up.

[0072] If the answer is Yes at step 1259, then at step 1500, the CPU C100 of the main control board M executes a game number topping-up execution process, which will be described later, and then proceeds to step 1400. On the other hand, even if the answer is No at step 1259, it also proceeds to step 1400. This game number topping-up execution process can execute the lottery using different lottery tables according to the state regarding the AT, but it is preferable that the lottery probability does not differ according to the set value (execute the lottery using the same lottery table). Next, at step 1400, the CPU C100 of the main control board M executes an AT state transition control process, which will be described later. Next, at step 1450, the CPU C100 of the main control board M executes a conditional device number management process, which will be described later.

[0073] Here, the states related to the AT in this example are enumerated and described in detail (also shown in the AT state transition diagram of FIG. 30). (1) The "low probability state" is a state where the AT has not been selected (has not acquired the right to transition to the "during-AT state"), and the bonus combination has not been selected. Since the "low probability state" is the so-called "normal state", it may also be referred to as the "normal state". (2) The "normal BB internal middle game" is a state where the BB combination has been selected in the "low probability state", the BB combination has not won, and the AT lottery has not been selected. (3) The "normal BB state" is a state executed when the symbol combination corresponding to the BB combination stops and is displayed in the situation where the BB combination has been selected in the "low probability state" and the AT lottery has not been selected, or when the symbol combination corresponding to the BB combination stops and is displayed in the "normal BB internal middle game". (4) The "high probability state" is a state where the AT lottery has not been selected (has not acquired the right to transition to the "during-AT state"), the bonus combination has not been selected, and it is a state where it is easier to be selected for the AT than the aforementioned "low probability state". As will be described later, when newly transitioning to the "high probability state", it is configured not to transition to the "low probability state" until the high-security game count has elapsed. (5) The "during-AT state" is a state where the AT (push-order navigation) is performed and the remaining game count of the AT (AT counter value) is subtracted. Even when the AT counter value becomes 0, if the subsequent continuous lottery is won, a predetermined value is set in the AT counter and the "during-AT state" continues. (6) The "precursor specialized state" is a state where the right to transition to the "boosted specialized state", which is a state where the AT game count is relatively more likely to be boosted compared to the "during-AT state", has been acquired. (7) The "boosted specialized state" is a state where the AT game count is relatively more likely to be boosted compared to the "during-AT state". (8) The "favorable BB internal middle game" is a state where the BB combination has been selected in the "high probability state", "during-AT state", "precursor specialized state" or "boosted specialized state", and the BB combination has not won. (9) The "waiting BB internal middle game" is a state where the BB combination has been selected in the "low probability state", the BB combination has been selected for the AT lottery, and the BB combination has not won.(10) The "advantage BB state" is a state that is executed when, in the "high probability state", "during AT state", "specialization precursor state", or "overlay specialization state", the symbol combination corresponding to the BB role is stopped and displayed when winning the BB role, or when the symbol combination corresponding to the BB role is stopped and displayed in the "advantage BB internal middle game", or when winning the BB role in the "low probability state", and winning the AT lottery by the BB role, and the symbol combination corresponding to the BB role is stopped and displayed, or when the symbol combination corresponding to the BB role is stopped and displayed in the "waiting BB internal middle game". (12) The "state for resurrection feasibility performance" is a state related to AT that transitions when the AT counter value becomes 0 and fails to win the subsequent continuous lottery. In the "state for resurrection feasibility performance", the subsequent resurrection lottery is executed. If winning the resurrection lottery, it transitions to the "during AT state" (a predetermined value is set in the AT counter), and if failing to win the resurrection lottery, it transitions to the "low probability state".

[0074] Next, in step 1550, the CPU C100 of the main control board M starts the rotation of all the reels, which will be described later, and proceeds to step 1261-1. Next, in step 1261-1, the CPU C100 of the main control board M determines whether there is a draw point creation request (requested to determine the stop positions of the rotating left reel M51, middle reel M52, and right reel M53, and appropriately requested according to the stop order and the stop positions of other reels). If Yes in step 1261-1, in step 1262, the CPU C100 of the main control board M creates a draw point and proceeds to step 1263. On the other hand, even if No in step 1261-1, it also proceeds to step 1263. Thus, in the "BB internal medium game", in the game that won the push order bell, if the stop buttons were not stopped in the correct push order for 11 payouts (for example, in the case of winning-A1, the stop buttons were not stopped in the order of "left → middle → right") (when the reels were stopped in an incorrect push order), the reel stop control (hereinafter, may also be referred to as "reel stop control" or simply "stop control") is configured such that a symbol combination that results in 11 payouts wins. Next, in step 1263, the CPU C100 of the main control board M executes a reel stop acceptance check. Next, in step 1264, the CPU C100 of the main control board M determines whether there has been an operation of any of the stop buttons (left stop button D41, middle stop button D42, right stop button D43). If Yes in step 1264, in step 1265, the CPU C100 of the main control board M determines the stop position of the reel corresponding to the operated stop button (for example, the left reel M51 corresponds to the left stop button D41). On the other hand, even if No in step 1264, it proceeds to step 1266. Next, in step 1266, the CPU C100 of the main control board M executes an all-reel stop check process. Next, in step 1267, the CPU C100 of the main control board M determines whether all the reels (left reel M51, middle reel M52, right reel M53) have stopped. If Yes in step 1267, in step 1268, the CPU C100 of the main control board M compares the symbol stop position data in the RAM with the internal winning combination stopable position data.Next, in step 1269, the CPU C100 of the main control board M determines whether the combination of the displayed symbols is normal (if it does not match the winning combination determined by the internal lottery, it is determined to be abnormal). Note that the determination of whether the combination of the displayed symbols in step 1269 is normal is to determine whether the stop control of the reels based on the operation of the stop button has been completed normally. In a game where a winning combination is won, when the operation of the stop button is executed in an operation mode in which the winning combination is winnable, even if the actually stopped reel position is not normal (the winning combination determined by the internal lottery is not stopped and displayed as seen by the player), if the stop control of the reels is normally executed and completed by the processing inside the gaming machine, the payout of game medals based on the winning of the winning combination is configured to be executed. If the result in step 1269 is Yes, the process proceeds to step 1274. On the other hand, if the result in step 1269 is No, in step 1270, the CPU C100 of the main control board M sets a display determination error display (for example, set it in the register area). Next, in step 1300, the CPU C100 of the main control board M executes an irrecoverable error process. On the other hand, if the result in step 1267 is No, the process proceeds to step 1261-1.

[0075] Next, at step 1274, the CPU C100 of the main control board M executes the payout process of the game medals due to a win. Next, at step 1275, the CPU C100 of the main control board M determines whether there has been a winning that pays out game medals {when the game medals obtained by winning exceed the maximum number of credits (in this example, 50), the payout of game medals is executed}. If Yes at step 1275, at step 1276, the CPU C100 of the main control board M turns on the hopper drive flag (a flag that is turned on when driving the hopper motor H80) and executes the payout of one game medal. Next, at step 1277, the CPU C100 of the main control board M determines whether the first payout sensor H10s or the second payout sensor H20s is on (when the first payout sensor H10s or the second payout sensor H20s is on, it is determined that the payout operation of one game medal is being performed). If Yes at step 1277, the process proceeds to step 1286.

[0076] On the other hand, if No at step 1277, at step 1279, the CPU C100 of the main control board M determines whether a predetermined time (for example, 5 seconds) has elapsed after driving the hopper (after the timing of the process in step 1276). If Yes at step 1279, at step 1280, the CPU C100 of the main control board M turns on the medal empty error flag (for example, updates the area corresponding to turning on within the medal empty error flag area in the RAM area). Next, at step 1281, the CPU C100 of the main control board M executes the medal empty error display on the 7-segment LED. Next, at step 1282, the CPU C100 of the main control board M determines whether the medal empty error has been cleared (for example, whether the setting / reset button M30 has been pressed). If Yes at step 1282, at step 1283, the CPU C100 of the main control board M turns off the medal empty error flag (for example, updates the area corresponding to turning off within the medal empty error flag area in the RAM area) and proceeds to step 1286. On the other hand, if No at step 1282, the process proceeds to step 1281.

[0077] Next, at step 1286, the CPU C100 of the main control board M determines whether the first payout sensor H10s and the second payout sensor H20s are off (after the first payout sensor H10s or the second payout sensor H20s turns on, when the first payout sensor H10s and the second payout sensor H20s turn off, it is determined that the payout operation of one gaming medal for which the payout operation was being performed has been completed). If Yes at step 1286, at step 1288, the CPU C100 of the main control board M turns off the hopper drive flag and proceeds to step 1290. Incidentally, if No at step 1279 or step 1286, the process proceeds to step 1277. Next, at step 1290, the CPU C100 of the main control board M determines whether the payout corresponding to the said winning (the winning that became Yes at step 1275) has been completed. If Yes at step 1290, the process proceeds to step 3400. Incidentally, if No at step 1286, the process proceeds to step 1277, if No at step 1275, the process proceeds to step 3400, and if No at step 1290, the process proceeds to step 1276.

[0078] Next, at step 3400, the CPU C100 of the main control board M executes the remaining game count management process, which will be described later. Next, at step 1700, the CPU C100 of the main control board M executes the RT state transition control process, which will be described later. Next, at step 1750, the CPU C100 of the main control board M executes the AT state start control process, which will be described later. Next, at step 3500, the CPU C100 of the main control board M executes the game section transition control process, which will be described later. Next, at step 1293, the CPU C100 of the main control board M executes game end processing (for example, clearing the bet number, game state transition processing, etc.) and proceeds to the next process (the process of step 1202).

[0079] Next, FIG. 19 is a flowchart of internal lottery execution processing according to the subroutine of step 3600 in FIG. 18 in the first embodiment. First, in step 3602, the CPU C100 of the main control board M sets an internal lottery table (a table used when executing an internal lottery, which stores settings such as numbers to be compared with winning numbers and acquired random numbers), and proceeds to step 3604. Next, in step 3604, the CPU C100 of the main control board M acquires the winning number related to the set internal lottery table address. Note that winning / re-play winning information can be generated from the winning number. Also, when a bonus and a minor winning combination overlap in winning, or when a bonus and a re-play winning combination overlap in winning, both the winning information of the winning / re-play winning information and the bonus winning information can be generated from the winning number. Specific generation processing will be described later. Next, in step 3606, the CPU C100 of the main control board M acquires the number of repetitions related to the set internal lottery table address. Here, the number of repetitions is the number of consecutive winning numbers with the same ball output group number and the same setting number for comparison with the acquired random number, and is stored in advance in the ROM of the main control board M. For example, the ball output group number 2 includes 9 winning numbers from winning number 4 to 12. For the consecutive 3 winning numbers 4 to 6, which are the winning numbers of the push-order re-play winning combination, the setting number is the same, and for the consecutive 6 winning numbers 7 to 12, which are the winning numbers of the push-order bell winning combination, the setting number is the same. Therefore, the number of repetitions related to the push-order re-play winning combination is 3, and the number of repetitions related to the push-order bell winning combination is 6. Note that the lottery table used when acquiring the winning numbers 4 to 6, which are the push-order re-play winning combination, and the lottery table used when acquiring the winning numbers 7 to 12, which are the push-order bell winning combination, are configured as a single lottery table. Next, in step 3608, the CPU C100 of the main control board M acquires the ball output group number related to the set internal lottery table address, and proceeds to step 3610.

[0080] Next, in step 3610, the CPU C100 of the main control board M acquires the set value data. Next, in step 3612, the CPU C100 of the main control board M acquires the designated address data. Next, in step 3614, the CPU C100 of the main control board M determines whether it has won the internal lottery (whether the acquired random number exists in the internal lottery table searched this time). If the result in step 3614 is Yes, since it is determined that it has won the internal lottery, the subsequent determination (lottery) regarding the internal lottery table address is not executed, and the process proceeds to the next process (the process of step 1259). On the other hand, if the result in step 3614 is No, in step 3616, the CPU C100 of the main control board M updates the number of repetitions. Next, in step 3618, the CPU C100 of the main control board M determines whether there are any remaining repetitions. If the result in step 3618 is Yes, the process proceeds to step 3610, and the processes of steps 3610 to 3618 are repeatedly executed until there are no remaining repetitions or the internal lottery is won. Incidentally, if the result in step 3618 is No, in step 3620, the CPU C100 of the main control board M updates the internal lottery table address (updates it to the address corresponding to the next winning group number), and the process proceeds to step 3604 to execute the processes after step 3604. Incidentally, the specific process of the internal lottery will be described later.

[0081] Next, FIG. 20 is a flowchart of the game number addition execution process according to the subroutine of step 1500 in FIG. 18 in the first embodiment. First, in step 1502, the CPU C100 of the main control board M determines whether the state regarding AT is the "during-AT state", the "pre-specialization state", or the "specialized addition state". If Yes in step 1502, in step 1504, the CPU C100 of the main control board M determines whether the winning ball group number related to the game is the winning ball group number related to the AT in-game addition role (in the "during-AT state", it is the winning number that can add the remaining AT game numbers, and in this example, it is Re-game - B, Re-game - C, Winning - D) (in this example, 1, 3). If Yes in step 1504, the process proceeds to step 1514. Also, if No in step 1502, in other words, if the state regarding AT is the advantageous BB state, in step 1512, the CPU C100 of the main control board M determines whether the winning ball group number related to the game is the winning ball group number related to the BB in-game addition role (in the "advantageous BB state", it is the winning number that can add the remaining AT game numbers, and in this example, it is Winning - H, Winning - I) (in this example, 5, 6). If Yes in step 1512, the process proceeds to step 1514, and if No in step 1512, the process proceeds to step 1518. Also, if No in step 1504, in step 1506, the CPU C100 of the main control board M determines whether the state regarding AT is the "specialized addition state". If Yes in step 1506, in step 1508, the CPU C100 of the main control board M determines whether the winning ball group number related to the game is the winning ball group number related to the specialized in-game addition role (in the "specialized addition state", it is the winning number that can add the remaining AT game numbers and cannot add the remaining AT game numbers in the "during-AT state", and in this example, it is Re-game - A, Re-game - D1~D3, Winning - A1~A6) (in this example, 2, 13). If Yes in step 1508, the process proceeds to step 1514. Incidentally, if No in step 1506 or step 1508, the process proceeds to step 1518.

[0082] Next, in step 1514, the CPU C100 of the main control board M refers to the additional game number lottery table at the time of winning, and determines the additional AT game number based on the winning ball group number related to the game (for example, in the lottery table shown outside the column, it is determined by whether the latched random number value falls within a certain range). Note that determining the additional AT game number is also referred to as executing the additional AT lottery. Next, in step 1516, the CPU C100 of the main control board M adds the determined additional AT game number to the counter value of the AT counter M60, and sets the AT counter value after the addition to the AT counter M60. Next, in step 1517, the CPU C100 of the main control board M sets a command related to the determined additional AT game number (a command to the sub-control board S side, and by receiving this command, the sub-control board S can recognize whether the additional AT game number has been executed and how many additional games there are). Then, it proceeds to step 1518. Note that in the case of the winning ball group numbers 7 to 11, which are the winning ball group numbers related to the winning numbers including the bonus (winning numbers 19 to 27), the lottery related to AT (AT lottery, additional AT lottery) can also be executed.

[0083] Here, the lottery table shown outside the column in the figure is an example of the additional game number lottery table at the time of winning. In the first embodiment, when the additional winning combination at the time of winning wins in a part of the state related to AT where the push order navigation is executed (in this example, "during AT state", "specialization precursor state", "specialized additional state", "advantageous BB state"), based on the winning ball group number related to the game, the additional AT game number is determined by lottery from "0" to "300", and the determined value is added to the counter value of the AT counter M60. Note that when "0" is determined, the remaining AT game number will not increase (when "0" is determined, it may be referred to as non-winning in the additional AT lottery).

[0084] Also, the average value (expected value) of the number of AT bonus games when elected as an additional winning role is as shown in the figure. As a specific calculation method, when the elected role is watermelon A, it can be calculated as {number of placements (600) × number of AT bonus games (0) + number of placements (100) × number of AT bonus games (10) + number of placements (300) × number of AT bonus games (30) + number of placements (24) × number of AT bonus games (100)} / total number of placements (1024) = 12.1 (games).

[0085] Next, when the elected role is replay - B or replay - C, it can be calculated as {number of placements (500) × number of AT bonus games (0) + number of placements (200) × number of AT bonus games (50) + number of placements (300) × number of AT bonus games (100) + number of placements (24) × number of AT bonus games (300)} / total number of placements (1024) = 46.1 (games).

[0086] Next, when the elected role is replay - A or replay - D1~D3, winning - A1~A6, it can be calculated as {number of placements (300) × number of AT bonus games (10) + number of placements (600) × number of AT bonus games (30) + number of placements (124) × number of AT bonus games (50)} / total number of placements (1024) = 26.61 (games). Note that when the elected role is replay - A or replay - D1~D3, winning - A1~A6, the AT games are only bonus - specialized state for AT - related status.

[0087] Next, when the elected role is a BB medium - weak rare role, it can be calculated as {number of placements (800) × number of AT bonus games (0) + number of placements (100) × number of AT bonus games (10) + number of placements (100) × number of AT bonus games (30) + number of placements (24) × number of AT bonus games (100)} / total number of placements (1024) = 6.3 (games).

[0088] Next, when the winning combination is a BB medium-strong rare combination, it can be calculated as follows: {Number of bets (300) × Number of additional AT games (0) + Number of bets (300) × Number of additional AT games (30) + Number of bets (400) × Number of additional AT games (50) + Number of bets (24) × Number of additional AT games (300)} / Total number of bets (1024) = 35.4 (games).

[0089] Furthermore, in the first embodiment, when the additional AT lottery is executed, the average value of the number of additional AT games may differ depending on the type of the winning combination, but depending on the set value, the average value of the number of additional AT games may be configured not to differ. Here, when configured to execute the additional AT lottery based on the winning number, for example, when the same process is executed as the additional AT lottery for winning numbers 7 and 8, a process for determining whether the winning number is 7 or 8 must be executed. However, as in the first embodiment, by configuring to execute the additional AT lottery based on the ball output group number, when the same process is executed as the additional AT lottery for winning numbers 7 and 8, it becomes possible to execute the process related to the additional AT lottery for either winning number 7 or 8 by only determining whether the ball output group number is 2.

[0090] Returning to the description of the flowchart, next, in step 1518, the CPU C100 of the main control board M determines whether the winning number related to the game (or it may be determined by winning / prize-winning / re-play winning information, or the number of balls put out group number, etc.) is a winning number related to Re-play - B (a reverse push white 7 replay which is a re-play in which a white seven can be aligned in a straight line on the invalid line by stopping with a reverse push). If Yes in step 1518, in step 1520, the CPU C100 of the main control board M determines whether there is an additional AT game count due to Re-play - B, in other words, whether the additional AT game count due to winning Re-play - B is not zero. If Yes in step 1520, in step 1522, the CPU C100 of the main control board M sets a reverse push instruction command (a command to the sub-control board S side, which will execute an effect of instructing to align the white seven on the invalid line with a reverse push ("right → middle → left")), and proceeds to step 1526. On the other hand, if No in step 1520, in step 1524, the CPU C100 of the main control board M sets a reverse push avoidance command (a command to the sub-control board S side, which will execute an effect of instructing a push order other than a reverse push ("right → middle → left") and preventing the white seven from being aligned on the invalid line), and proceeds to step 1526. Still, even if No in step 1518, it proceeds to step 1526. Next, in step 1526, the CPU C100 of the main control board M determines whether the winning number related to the game (or it may be determined by winning / prize-winning / re-play winning information, or the number of balls put out group number, etc.) is Re-play - C (a forward push black 7 replay which is a re-play in which a black seven can be aligned in a straight line on the invalid line by stopping with a forward push). If Yes in step 1526, in step 1528, the CPU C100 of the main control board M determines whether there is an additional AT game count due to Re-play - C, in other words, whether the additional AT game count due to winning Re-play - C is not zero.If the answer is Yes in step 1528, in step 1530, the CPU C100 of the main control board M sets a sequential press instruction command (a command to the sub-control board S, which is to execute an effect of instructing to align the black sevens on the invalid lines in the order of sequential press ("left → middle → right")), and proceeds to the next process (the process of step 1400). On the other hand, if the answer is No in step 1528, in step 1532, the CPU C100 of the main control board M sets a sequential press avoidance command (a command to the sub-control board S, which is to instruct a pressing order other than the sequential press ("left → middle → right") and execute an effect of preventing the black sevens from being aligned on the invalid lines), and proceeds to the next process (the process of step 1400). Incidentally, even if the answer is No in step 1526, the process proceeds to the next process (the process of step 1400). In the first embodiment, the reverse press instruction command, the reverse press avoidance command, the sequential press instruction command, and the sequential press avoidance command are transmitted to the sub-control board S, and when the sub-control board S receives these commands, an effect related to the pressing order guidance is configured to be executable on the sub-control board S side. However, the present invention is not limited to this. When winning the AT addition lottery, a command indicating that the AT addition lottery has been won and the number of AT addition games (for example, the command related to the number of AT addition games in the process of step 1517) may be transmitted to the sub-control board S side. When the sub-control board S side receives the command, the sub-control board S side may be configured to determine the execution timing and the effect mode of the effect related to the pressing order guidance. As an example, in a game in which replay - B has won, an effect mode of instructing a reverse press may be selected and executed in the game (a game with an AT game number addition) in which the sub-control board S side has received the command, or in the game in which the sub-control board S side has received the command, an effect of instructing a reverse press may not be executed, and in a game that satisfies a subsequent predetermined condition (for example, winning a specific replay role (for example, replay - B or C)), an effect of instructing a pressing order that allows 7 - of - a - kind on the invalid lines may be executed.Or, in the game where Re - play - B is selected and the command is received on the sub - control board S side (a game with an additional AT game count), an effect instructing a reverse push is not executed. After that, in a game that satisfies a predetermined condition (for example, after a predetermined number of games (simultaneously, a continuous effect may be executed, and in that case, in the final game of the continuous effect)), an AT game count increase effect (an effect in which the display related to the remaining AT game count displayed on the effect display device S40 increases, for example, displayed as “+30G”) may be executed. In this example, the effect display device S40 is also configured to be able to display the display related to the remaining AT game count, and this display may be the same as or different from the remaining AT game count stored on the main - control board side. Also, as an example of a game where Re - play - B is selected and the command is received on the sub - control board S side (a game with an additional AT game count), when an effect instructing a reverse push is not executed and an AT game count increase effect is executed in a game that satisfies a subsequent predetermined condition, for example, when the sub - control board S side is executing a special effect (for example, a predetermined continuous effect) to encourage the winning of a bonus (since the winning probability of Re - play - B is low (including 0%) during the bonus, if the pushing order that enables a complete set of 7 is notified, the player will recognize that the bonus has not been won). Also, as information for the sub - control board S side to determine that the main - control board M side has won the AT increase lottery and there is an increase in the remaining AT game count, (1) Information regarding the remaining AT game count is transmitted from the main - control board M side to the sub - control board S side after the AT increase lottery. Then, on the sub - control board S side, the difference between the information regarding the remaining AT game count transmitted last time and the information regarding the remaining AT game count transmitted this time is calculated to grasp the number of AT increase games won in the AT increase lottery. (2) A command regarding the number of AT increase games obtained as a result of the AT increase lottery on the main - control board M side is transmitted to the sub - control board S side. Also, when not winning the AT increase lottery, a command indicating not winning the AT increase lottery is transmitted to the sub - control board S side, and when the sub - control board S side receives the command, the sub - control board S side may be configured to determine the effect mode of the effect regarding the push - order navigation.As an example, it may be configured to select and execute a presentation mode that instructs a middle press (which is to operate the middle stop button as the first stop and is a pressing order to avoid seven-of-a-kind) in a game in which replay-B is a winning game and the command is received on the sub-control board S side (a game without an AT game number bonus). Incidentally, although the AT bonus lottery is executed on the main control board M side, as information for the sub-control board S side to determine that there is no bonus for the remaining AT game number, (1) information regarding the remaining AT game number is transmitted from the main control board M side to the sub-control board S side after the AT bonus lottery. Thereafter, on the sub-control board S side, the difference between the information regarding the remaining AT game number transmitted last time and the information regarding the remaining AT game number transmitted this time is calculated, and the number of AT bonus games won in the AT bonus lottery is grasped (when the value obtained by subtracting the information regarding the remaining AT game number transmitted this time from the information regarding the remaining AT game number transmitted last time is 1, it is determined that the AT bonus lottery was not won), (2) a command indicating that the number of AT bonus games is 0 games as a result of the AT bonus lottery on the main control board M side is transmitted to the sub-control board S side.

[0091] Next, FIG. 21 is a flowchart (the first page) of the AT state transition control process related to the subroutine of step 1400 in FIG. 18 in the first embodiment. First, in step 1402, the CPU C100 of the main control board M determines whether the state regarding the current AT is a state regarding an AT in which an AT lottery can be executed. In the first embodiment, the state regarding an AT in which an AT lottery can be executed is only the "high probability state". By winning the BB in the "high probability state", it transitions to the "advantageous BB internal middle game", and then by winning the BB combination, it transitions to the "advantageous BB state". When the executed BB ends, it transitions to the "during-AT state", and an initial value of 50 times of the AT game count is set in the AT counter. Even if the BB is won in the "low probability state", it transitions to the "normal BB internal middle game" and does not transition to the "during-AT state" thereafter. Note that this is not limiting, and it may be configured such that when the BB is won in the "normal game state", it can win the AT lottery triggered by the BB combination. When configured in such a way, when the BB is won in the "normal game state" and wins the AT lottery triggered by the BB combination, it transitions to the "advantageous BB internal middle game", and then by aligning the BBs, it transitions to the "advantageous BB state". In the state during the normal game state when the BB is won and the BBs are not aligned, the game section may be set as the "advantageous section" or the "standby section". If the result in step 1402 is Yes, in step 1404, the CPU C100 of the main control board M determines whether the conditional device related to the game is an AT lottery winning combination (in this example, the first type BB-A or the first type BB-C which is a BB combination with no setting difference). In the first embodiment, both the winning numbers of the BB combination with no setting difference alone (winning numbers 19, 24) and the winning numbers in which the BB combination with no setting difference and small winning combinations overlap (winning numbers 25, 26, 27) are AT lottery winning combinations. If the result in step 1404 is Yes, in step 1406, the CPU C100 of the main control board M determines that the state regarding the AT after the next game is the "advantageous BB internal middle game" and proceeds to step 1410. Also, even if the result in step 1402 or step 1404 is No, it proceeds to step 1410.In the first embodiment, the AT winning rate (whether it can win or not) related to the AT lottery is configured to be different when the state related to the AT is different. However, when the state related to the AT is the same, even if the set value is different, the AT winning rate related to the AT lottery is the same (when winning the BB in the "high probability state", it always wins the AT regardless of the set value = then it shifts to the "during AT state").

[0092] Next, in step 1410, the CPU C100 of the main control board M determines whether the state related to the AT after the next game has been determined. If it is Yes in step 1410, in step 1412, the CPU C100 of the main control board M determines whether the current state related to the AT is the "low probability state". If it is Yes in step 1412, in step 1414, the CPU C100 of the main control board M determines whether the condition device related to the game is a state upgrade combination (a small combination that can shift from the "low probability state" to the "high probability state" by winning. In this example, it is a cherry). If it is Yes in step 1414, in step 1416, the CPU C100 of the main control board M executes a high probability state transition lottery to win at a predetermined probability (in this example, it is 1 / 2, and there is no problem if it is changed as long as it is not different according to the set value). Next, in step 1418, the CPU C100 of the main control board M determines whether it has won the executed high probability state transition lottery. If it is Yes in step 1418, in step 1420, the CPU C100 of the main control board M determines the state related to the AT after the next game as the "high probability state" and proceeds to step 1430.

[0093] Also, if the answer is "No" in step 1412, in step 1424, the CPU C100 of the main control board M determines whether the current state regarding the AT is the "high probability state". If the answer is "Yes" in step 1424, in step 1426, the CPU C100 of the main control board M determines whether the counter value of the high probability guarantee counter KHc is 1 (the final game of high probability guarantee, the 10th game since the "high probability state" was entered). If the answer is "Yes" in step 1426, in step 1428, the CPU C100 of the main control board M determines whether the low probability transition conditions are satisfied. Here, in the first embodiment, when the state regarding the AT is the "high probability state", the game section is the "advantageous section", and when the game section is the "advantageous section", the draw order navigator is executed one or more times, or the "advantageous section" is configured not to end unless the "advantageous section" continues for a predetermined number of games (in this example, 1500 games) (that is, even if the lottery for low probability state transition is won, if the low probability transition conditions are not satisfied, such as the draw order navigator not being executed at least once, the "high probability state" is configured not to end). Incidentally, if a BB combination is won and BB is executed during the "advantageous section", the "advantageous section" may be configured to end at an arbitrary timing even if the draw order navigator has not been executed at all during the "advantageous section". If the answer is "Yes" in step 1428, in step 1429, the CPU C100 of the main control board M determines that the state regarding the AT after the next game and subsequent games is the "low probability state", and proceeds to step 1430. Here, the low probability transition conditions are satisfied by the draw order navigator being executed once. Incidentally, when there are winning numbers with different winning rates for the player and different maximum payout numbers of 8 and 11 as the draw order combination (winning combination), the execution of the draw order navigator for the winning combination with the larger maximum payout number of 11 may be set as the low probability transition condition. Incidentally, when the answer is "No" in step 1410, step 1414, step 1418, step 1424, step 1426 or step 1428, the process also proceeds to step 1430.Thus, in the first embodiment, when newly transitioning to the "high probability state", 10 games, which are high probability guarantee games, are set in the high probability guarantee counter KHc, and it is configured not to transition to the "low probability state" until the counter value becomes 0. Note that such a lottery method is merely an example. For example, after transitioning to the "high probability state", the low probability state transition lottery is not executed for 10 games (the stay in the "high probability state" is guaranteed), and after the elapse of the 10 games, a lottery for transitioning from the "high probability state" to the "low probability state" may be executed at a predetermined probability (e.g., 1 / 20) for each game. Note that the AT lottery roles (low probability AT lottery role, high probability AT lottery role) and the state promotion roles have the same winning probability for all set values.

[0094] Next, FIG. 22 is a flowchart (second sheet) of the AT state transition control process according to the subroutine of step 1400 in FIG. 18 in the first embodiment. First, in step 1430, the CPU C100 of the main control board M determines whether the current state regarding the AT is the "during AT state". If Yes in step 1430, in step 1431, the CPU C100 of the main control board M determines whether the counter value of the AT counter M60 is equal to or greater than a predetermined value (in this example, 4). Here, in the first embodiment, when the state regarding the AT is the "during AT state", if the AT counter value is 4 or more, in other words, if the remaining number of AT games is 4 or more, the right to transition to the "boost specialization state" can be acquired with a probability of 1 / 2 when winning the watermelon B, and can transition to the "precursor to specialization state". On the other hand, when the state regarding the AT is the "during AT state", if the AT counter value is 3 or less, in other words, if the remaining number of AT games is 3 or less, even if winning the watermelon B, a lottery (sometimes also referred to as a specialization state transition lottery) for acquiring the right to transition to the "boost specialization state" is not executed, and it is configured not to transition to the "precursor to specialization state" and the "boost specialization state". Note that this is not limited thereto, and even when the AT counter value is 3 or less, a lottery (sometimes also referred to as a specialization state transition lottery) for winning the right to transition to the "boost specialization state" when winning the watermelon B may be executed. If configured in this way and winning the lottery for winning the right to transition to the "boost specialization state" when winning the watermelon B in a situation where the AT counter value is 3 or less, it may be configured to become the "precursor to specialization state" or the "boost specialization state" (be able to transition thereto) from the next game after winning the lottery. Or it may be configured to become the "precursor to specialization state" or the "boost specialization state" (be able to transition thereto) when the AT counter value becomes a predetermined value (for example, 1 or 0). Or it may be configured to become the "precursor to specialization state" or the "boost specialization state" (be able to transition thereto) after executing a predetermined number of games from the game in which the lottery is won. Also, when transitioning to the "boost specialization state", it is not necessarily required to go through the "precursor to specialization state". For example, it may be configured to directly transition from the "during AT state" to the "boost specialization state".If the answer is Yes in step 1431, then in step 1432, the CPU C100 of the main control board M determines whether the conditional device related to the game is a specialized transition role (a minor role that can execute a lottery to obtain the right to transition to the "overlay specialization state", which is a watermelon B in this example). If the answer is Yes in step 1432, then in step 1433, the CPU C100 of the main control board M executes a specialization state transition lottery to win with a predetermined probability (1 / 2 in this example). Next, in step 1434, the CPU C100 of the main control board M determines whether it has won the executed specialization state transition lottery. If the answer is Yes in step 1434, then in step 1435, the CPU C100 of the main control board M determines the state related to the AT after the next game as the "specialization precursor state" and proceeds to step 1444-1. On the other hand, if the answer is No in step 1431, then in step 1436, the CPU C100 of the main control board M determines whether the counter value of the AT counter M60 is 1 (when the AT counter value is 1, it is the final AT game). If the answer is Yes in step 1436, then in step 1437, the CPU C100 of the main control board M executes a continuation lottery to win with a predetermined probability (2 / 3 in this example). Next, in step 1438, the CPU C100 of the main control board M determines whether it has won the executed continuation lottery. If the answer is Yes in step 1438, then in step 1439, the CPU C100 of the main control board M determines the state related to the AT after the next game as the "during-AT state" and proceeds to step 1444-1 (the initial AT game number (50 in this example) will be set in the AT counter to satisfy the AT state transition possible condition). On the other hand, if the answer is No in step 1438, then in step 1443, the CPU C100 of the main control board M determines the state related to the AT after the next game as the "state for resurrection performance" and proceeds to step 1444-1. Still, even if the answer is No in step 1430, step 1432, step 1434, or step 1436, it proceeds to step 1444-1. Thus, in the first embodiment, a continuation lottery is executed in the final AT game, and when winning the continuation lottery, the initial value of 50 games is set again in the AT counter M60. That is, when not considering the AT game number increase, the gaming property is such that the AT of 50 games per set loops continuously with a probability of 2 / 3.Furthermore, the execution timing of the continuous lottery is not limited to the final AT game. For example, it may be configured to execute the continuous lottery in the first game of the AT (the first game in which the "in-AT state" is newly entered or the first game after the initial value is set in the AT counter M60). By configuring it in this way, since it is determined whether the next set (the AT related to winning the continuous lottery) has already been executed (whether the AT continues) in the "in-AT state", it is possible to make the in-AT effects different between the case of winning the continuous lottery and the case of not winning the continuous lottery. For example, when winning the continuous lottery, the BGM can be changed (such as a song playing, etc.) in a situation where the counter value of the AT counter M60 is 1 or more (during the execution of the AT), or an effect that makes it certain that the continuous lottery has been won can be executed.

[0095] Next, FIG. 23 is a flowchart (the third sheet) of the AT state transition control process according to the subroutine of step 1400 in FIG. 18 in the first embodiment. First, in step 1444-1, the CPU C100 of the main control board M determines whether the current state regarding AT is a state for resurrection performance. If Yes in step 1444-1, in step 1444-2, the CPU C100 of the main control board M determines whether the conditional device regarding the game is a resurrection role (a role that can transition to the "during-AT state" in the next game by being elected in the "state for resurrection performance", in other words, a role that can pull back the AT). Here, in the first embodiment, the resurrection roles include any one of watermelon A, watermelon B, cherry, and bonus roles (only the BB role without a setting difference, and the BB role with a setting difference is not included), and the case where the conditional device regarding the game becomes a resurrection role is referred to as winning the resurrection lottery. If Yes in step 1444-2, in step 1444-3, the CPU C100 of the main control board M determines the state regarding AT after the next game as the "during-AT state" and proceeds to step 1445. Here, the initial AT game number (50 in this example) is set in the AT counter to satisfy the AT state transition possible condition. On the other hand, if No in step 1444-2, in step 1444-4, the CPU C100 of the main control board M determines the state regarding AT after the next game as the "low-probability state" and proceeds to step 1445. Note that even if No in step 1441-1, it also proceeds to step 1445. Thus, in the first embodiment, even when it becomes the final AT game and fails to win the continuous lottery, if it transitions to the "state for resurrection performance" and can win the resurrection lottery in the "state for resurrection performance", it is configured to transition to the "during-AT state" from the next game. Note that the "state for resurrection performance" is an "advantageous section", but the lottery regarding AT in the "during-AT state" (AT bonus lottery, continuous lottery, etc.) is not executed, and it is configured to be able to execute the resurrection lottery. The execution mode of the lottery regarding AT is different between the "during-AT state" and the "state for resurrection performance".

[0096] Next, in step 1445, the CPU C100 of the main control board M determines whether the state regarding the AT after the next game has been determined. If it is Yes in step 1445, then in step 1446, the CPU C100 of the main control board M determines whether the transition conditions for the state regarding the AT are satisfied (for example, as shown in FIG. 30, it is satisfied when 10 games, which is the number of precursor games in the "specialization precursor state", are completed). If it is Yes in step 1446, then in step 1447, the CPU C100 of the main control board M determines the state regarding the AT after the next game and proceeds to step 1448 (for example, as shown in FIG. 30, when the number of precursor games is completed in the "specialization precursor state", it is determined as the "overlay specialization state"). Incidentally, even if it is No in step 1445 or step 1446, it also proceeds to step 1448. Next, in step 1448, the CPU C100 of the main control board M sets a high-security guarantee counter value command (in this example, it is a command to the sub side, which is a command regarding the current high-security guarantee counter value, in other words, the remaining number of games for which the high-probability state is guaranteed) and proceeds to step 1449-1. Next, in step 1449-1, the CPU C100 of the main control board M determines whether the state regarding the AT after the next game is determined as the "advantage BB internal middle game". If it is Yes in step 1449-1, then in step 1449-2, the CPU C100 of the main control board M clears the counter value of the high-security guarantee counter K Hc to zero and proceeds to the next process (the process of step 1450). Incidentally, even if it is No in step 1499-1, it also proceeds to the next process (the process of step 1450).

[0097] Also, in the first embodiment, the AT winning rate is configured to vary depending on the lottery status. When winning the BB role (BB role without setting difference) in the "low probability state", the player does not win the AT transition lottery (and does not transition to the "AT in progress state" thereafter). On the other hand, when winning the BB role (BB role without setting difference) in the "high probability state", the player wins the AT transition lottery (and transitions to the "AT in progress state" thereafter). However, it is not limited to this. When configuring a conditional device A, which is a predetermined conditional device, as the AT lottery role and having "high probability state A" and "high probability state B" as the states related to AT, which is the "advantageous interval", it may be configured such that when winning the conditional device A in the "high probability state A", the player wins the AT transition lottery with a probability of 1 / 10, and when winning the conditional device A in the "high probability state B", the player wins the AT transition lottery with a probability of 1 / 2. Also, when winning the AT transition lottery, the player transitions to the "AT preparation state", which is a preparation state until transitioning to the "AT in progress state" as the state related to AT, and may be configured to transition to the "AT in progress state" when a predetermined end condition (for example, 10 games have elapsed since transitioning to the "AT preparation state") is satisfied.

[0098] Next, FIG. 24 is a flowchart of the conditional device number management process according to the subroutine of step 1450 in FIG. 18 in the first embodiment. First, in step 1451, the CPU C100 of the main control board M determines whether the current gaming section is an "advantageous section". If Yes in step 1451, in step 1452, the CPU C100 of the main control board M sets a command related to winning / re-play winning information (a command on the side of the sub-control board S, for example, a command related to winning / re-play winning information for the game). Next, in step 1454, the CPU C100 of the main control board M determines whether the conditional device related to the game is a device with a pressing order (a conditional device in which the winning combination differs depending on the pressing order, for example, winning-A1, etc.). If Yes in step 1454, in step 1458, the CPU C100 of the main control board M determines an instruction number (also referred to as a pressing order number) during the game based on the winning / re-play winning information related to the game, and stores it in a RAM address (a different address from the RAM address for displaying the pressing order navigation) for storing the instruction number. Note that the instruction number is information related to the pressing order, and in this example, it is determined by the main control board M and transmitted to the sub-control board S (details will be described later). Also, the sub-control board S can display the pressing order navigation on the effect display device S40 by receiving the instruction number. Note that even when the pressing order navigation is not executed, the instruction number is configured to be determined (although not shown in the figure, the instruction number becomes the initial value based on clearing the instruction number). Note that when executing a pressing order guessing game, it may be configured to determine a predetermined instruction number (for example, AX) dedicated to the pressing order guessing game. Next, in step 1460, the CPU C100 of the main control board M executes the pressing order navigation display on the pressing order display device D270 based on the instruction number related to the game (refer to FIG. 34 for the display image of the pressing order navigation on the main control board side). Next, in step 1466, the CPU C100 of the main control board M sets a command related to the instruction number determined in step 1458 (a command to the sub side) (for example, sets it in the register area), and proceeds to step 1472 (refer to FIG. 34 for the display image of the pressing order navigation on the sub-control board side).In this example, the stop order display device D270 and the effect display device S40 display the stop order of the reels that yields the highest profit for the player, which is referred to as push order navigation, display of push order navigation, etc. In the first embodiment, the push order navigation is displayed based on the instruction number. For example, the push order of "left → middle → right" is configured to be displayed as "=1" on the push order display device D270, and both in the case of the push order bell and the case of the push order replay game, it is configured to be displayed as "=1". Note that this is not limited thereto, and it may be configured such that the display mode is different between the case where the push order navigation of "left → middle → right" is displayed on the push order display device D270 in the game related to the push order bell and the case where the push order navigation of "left → middle → right" is displayed on the push order display device D270 in the game related to the push order replay game. That is, the number of types of the display mode of the push order navigation displayed on the push order display device D270 may be configured to be the same as the number of types of the winning / replay winning information.

[0099] Also, if the answer is "No" in step 1451 or step 1454, in step 1468, the CPU C100 of the main control board M executes a masking process on the winning and replay game winning information of the game, and stores the masked information at a predetermined address in the RAM. Here, if the winning and replay game winning information related to the game is transmitted to the sub-control board S side and the winning and replay game winning information is recognized due to improper behavior, the high-profit pressing order (reel stop order) related to the game will be recognized. Therefore, in this example, a masking process {a process of concealing the winning and replay game winning information (especially the information related to the pressing order)} is executed on the winning and replay game winning information related to the game, and then it is configured to be transmitted to the sub-control board S, so that a high-profit pressing order cannot be recognized. Note that as a method of the masking process in the first embodiment, a plurality of winning and replay game winning information (winning and replay game winning information having the same role is preferable, for example, a plurality of winning and replay game winning information in which a symbol combination that becomes a replay game role where the RT state transitions according to the pressing order can stop and be displayed) is set as one production group number (for example, setting winning and replay game winning information 4 to 6 as production group 4), and the production group number is configured to be transmitted to the sub-control board S side. Note that the method of the masking process is not limited to this. For example, after the provided winning and replay game winning information (in this example, 0 to 18), newly configured winning and replay game winning information after the masking process may be provided. Also, even in such a case, it is desirable to configure the masked winning and replay game winning information by setting a plurality of winning and replay game winning information among the existing winning and replay game winning information as one winning and replay game winning information like the production group number (for example, setting winning and replay game winning information 4 to 6 as winning and replay game winning information 19 (newly provided winning and replay game winning information) which is the winning and replay game winning information after the masking process). Note that when it is determined that the game is a game that notifies operation information (pressing order navigation) based on the state of AT in the main control board M, the winning and replay game winning information may be transmitted to the sub-control board S side, and the production group number may be transmitted to the sub-control board S side in a game that does not notify operation information. When configured in this way, the command related to the instruction number may be transmitted to the sub-control board S side, or may be configured not to be transmitted.

[0100] Next, in step 1470, the CPU C100 of the main control board M sets a command related to the production group number after executing the mask process (command to the sub side) (for example, set it in the register area), and proceeds to step 1472. Next, in step 1472, the CPU C100 of the main control board M sets a command related to bonus winning information (information that the sub side can recognize whether or not it has won the bonus) (command to the sub side) (for example, set it in the register area), and proceeds to the next process (process in step 1550). In the first embodiment, although it is configured to derive winning / re-play winning information and bonus winning information from the winning numbers, the derivation method will be described later. Also, as shown in the lower part of the figure, as a display example of the push order navigation, in the case of the "AT state", (1) when the falling re-play combination is included → navigate the push order in which the falling re-play combination is not stopped and displayed, (2) in the case of bells (1-piece combination · 11-piece combination) → navigate the push order that gives the most payout number of coins, etc. are configured. Thus, in the first embodiment, when the game section is the "advantageous section", winning / re-play winning information (numbers that can specify the type of winning combination and the most advantageous push order for the player) and instruction numbers (numbers that can specify the most advantageous push order for the player) can be transmitted to the sub control board S side, while when the game section is the "normal section", a production group number (a number that can only specify the outline of the winning combination) can be transmitted to the sub control board S side. That is, in the "advantageous section", the winning / re-play winning information related to the game, including the winning / re-play winning information in which the game result and the player's profit differ depending on the push order, can be directly transmitted to the sub control board S side, while in a game section that is not the "advantageous section", the winning / re-play winning information related to the game is not transmitted, and in the case of winning / re-play winning information in which the game result and the player's profit differ depending on the push order, a production group number with the information related to the push order concealed is transmitted to the sub control board S side.

[0101] When the game section is not the "advantageous section" or in other cases, when transmitting the winning and replay game winning information determined by the main control board M to the sub-control board S, a masking process is executed to determine the production group number, and the production group number is configured to be transmitted to the sub-control board S. The production group number is obtained by grouping the winning and replay game winning information according to the winning roles with the same role (for example, replay roles including the falling replay role, the push-order bell, etc.), and assigning numbers. By configuring to execute a masking process {a process of concealing the winning and replay game winning information (especially the information related to the push order)} on the winning and replay game winning information related to the game and then transmitting it to the sub-control board S, it is possible to prevent a situation where information related to the winning and replay game winning information is recognized due to improper behavior, and the push order (reel stop order) that results in high profits related to the game is recognized.

[0102] Next, FIG. 25 is a flowchart of the reel rotation start preparation process according to the subroutine of step 1550 in FIG. 18 in the first embodiment. First, in step 1552, the CPU C100 of the main control board M determines whether the timer value of the game interval minimum time timer M70 (subtraction timer) is 0. Here, the game interval minimum time timer M70 is a timer that measures the time (4.1 seconds in this example) that should be ensured from a certain game start timing (reel rotation start timing) to the next game start timing (reel rotation start timing). If Yes in step 1552, in step 1554, the CPU C100 of the main control board M newly sets the minimum time (sometimes referred to as the minimum game time, 4.1 seconds in this example) to the timer value of the game interval minimum time timer M70 and starts it. On the other hand, if No in step 1552, the CPU C100 of the main control board M executes an infinite loop process. Next, in step 1556, the CPU C100 of the main control board M clears the information related to the reel stop order and the information related to the pressing order for the ended game. Next, in step 1558, the CPU C100 of the main control board M clears the information related to the time during which the reel was stopped and the draw point creation request for the ended game. Next, in step 1560, the CPU C100 of the main control board M initializes the symbol stop position data related to the ended game. Next, in step 1562, the CPU C100 of the main control board M sets the output request during the reel rotation start standby for the game. Next, in step 1564, the CPU C100 of the main control board M sets the reel control command for the game and proceeds to the next process (the process of step 1260). In other words, by the processes of step 1562 and step 1564, a command for indicating to the sub-control board S that the reel starts to rotate becomes transmittable.

[0103] Next, FIG. 26 is a flowchart of the remaining game number management process according to the subroutine of step 3400 in FIG. 18 in the first embodiment. First, in step 3402, the CPU C100 of the main control board M determines whether the current game section is an "advantageous section". Although details will be described later, the "advantageous section" is one of the game sections, and it is a game section that is likely to be set in a game situation that is advantageous to the player, such as when the state regarding the AT is the "during-AT state". If Yes in step 3402, in step 3404, the CPU C100 of the main control board M decrements the counter value of the advantageous section remaining game number counter YKc-1 (a decrement counter, with an initial value of 1500, which is the maximum number of games that can stay in the "advantageous section", and can be decremented by one for each game during the period of the "advantageous section").

[0104] Next, in step 3408, the CPU C100 of the main control board M determines whether the current state regarding the AT is the "during-AT state". If it is Yes in step 3408, in step 3410, the CPU C100 of the main control board M decrements the AT counter value by 1. Next, in step 3412, the CPU C100 of the main control board M determines whether the state regarding the AT is a high-probability state. If it is Yes in step 3412, in step 3414, the CPU C100 of the main control board M decrements the counter value of the high-probability guarantee counter KHc and proceeds to the next process (the process of step 1700). Incidentally, even if it is No in step 3402, step 3408, or step 3412, the process also proceeds to the next process (the process of step 1700). Thus, in the first embodiment, when the state regarding the AT that the push-order navigation can display is the "during-AT state", the AT counter value is decremented for each game, but when it is the "advantage BB state", "advantage BB internal middle game", "specialization precursor state", or "added-on specialization state", the AT counter value is not decremented even if the game is executed. That is, when transitioning from the "during-AT state" to the "specialization precursor state" in a situation where the AT counter value remains (1 or more remains), it is configured to be able to transition (shift) as "during-AT state" → "specialization precursor state" → "added-on specialization state" while maintaining the AT counter value. Incidentally, even if the state regarding the AT is the "during-AT state", when the winning number including the bonus combination is determined in that game, the AT counter value can be prevented from being decremented by 1. At this time, for example, the AT counter value stored in the RAM of the main control board M is not decremented, but the display may be controlled so that the remaining number of AT games displayed on the effect display device S40 controlled by the sub-control board S is decremented.For example, when the AT counter value is "30" and the remaining AT game count displayed on the effect display device S40 is "30", if a game is executed and a bonus is won, the AT counter value maintains "30", or stores "30 + α", which is a value obtained by adding the value "α" obtained by the AT addition lottery related to the game. However, triggered by the operation of the start lever D50, it may display "29" as the remaining AT game count displayed on the effect display device S40, or "29 + α", which is a value obtained by adding the value "α" obtained by the AT addition lottery. (Note that "α" obtained by the addition lottery may not be notified in the game, but may be notified in a specific game after the game (when the bonus game starts, during the bonus game, at the end of the bonus game, or a game that meets a predetermined condition after the end of the bonus game)). Then, the remaining AT game count displayed on the effect display device S40 is also decremented by 1 for each game even in the "advantage BB internal game", and the remaining AT game count can be configured to be decremented for each game until an effect suggesting bonus determination (for example, a bonus determination screen) is output. By configuring it in this way, when a bonus is won in a state where a push-order navigation such as the "AT in progress state" can be executed, the player cannot immediately grasp the bonus win. That is, after the winning number including the bonus combination is determined, a continuous effect spanning multiple games that provokes whether the player has won the bonus can be executed using the effect display device S40 or the like, enhancing the interest of the game. Note that after the bonus game ends, when the remaining AT game count displayed on the effect display device S40 is "30" or, when notifying the result of winning the addition lottery and the addition, it can be controlled to display a value of "30" or more.When the game is executed and a bonus is won when the AT counter value is "1" and the remaining number of AT games displayed on the effect display device S40 is "1", the display related to the remaining number of AT games displayed on the effect display device S40 becomes "0". However, while maintaining this state, a continuous effect is executed over a plurality of games that provokes whether or not a bonus has been won. When the game is executed when the AT counter value is "1" and the remaining number of AT games displayed on the effect display device S40 is "1", and a winning number (or winning / re-play winning information, or payout ball group number) that can execute an AT addition lottery is won and the AT addition lottery is not won, the number of AT games becomes "0" and the number of AT games displayed on the effect display device S40 becomes "0". Also, when the remaining number of AT games is small, the probability of executing a continuous effect may be set lower (including 0%) than when the remaining number of AT games is large.

[0105] Next, FIG. 27 is a flowchart of the RT state transition control process related to the subroutine of step 1700 in FIG. 18 in the first embodiment. First, in step 1702, the CPU C100 of the main control board M determines whether or not the RT state transition possible condition is satisfied in the game. Here, in the first embodiment, the RT state transition possible condition is configured to be satisfied by the execution of RAM clear (initialization of RAM), the stop display of re-play (in this example, the stop display of re-play 04), and the winning / starting / ending of BB. If Yes in step 1702, in step 1704, the CPU C100 of the main control board M determines the RT state transition possibility and the RT state after the next game based on the satisfied RT state transition possible condition (refer to the RT state transition diagram in FIG. 28), and proceeds to the next process (the process in step 1750). Also, even if No in step 1702, the process proceeds to the next process (the process in step 1750). In the first embodiment, the RT state transition control process is executed after all reels stop. However, when transitioning to "RT1", the transition timing may be at the time of lever on. The timing for transitioning the RT state (storing the RT number in the RAM) can be determined as appropriate.

[0106] Next, FIG. 28 is an RT state transition diagram in the first embodiment. In the first embodiment, there are four RT states, "RT0" to "RT2" and "one type BB-A, B, C", and the RT state transitions by satisfying the conditions shown by the arrows in the figure. As a specific example of the RT state transition, when the RT state is "RT1", RAM initialization is executed, or when the replay game 04 stops being displayed, the state transitions to "RT0". The replay game 04 stopping being displayed specifically means that when "Replay-D1" is won in a situation where the RT state is "RT1", if the left stop button is operated as the first stop, the replay games 01 to 03 stop being displayed and the RT state remains "RT1". On the other hand, when "Replay-D1" is won in a situation where the RT state is "RT1", if the middle stop button or the right stop button is operated as the first stop, the replay game 04 stops being displayed and the RT state transitions from "RT1" to "RT0".

[0107] Also, when the RT state is "RT0" or "RT1", if one wins the BB role and does not win the BB role in the selected game (the conditional device related to one type of BB - A, B, C operates), the RT state transitions to "RT2". Also, when winning the BB role in "RT2" (one type of BB - A, B, C operates), it transitions to "one type of BB - A, B, C". Also, when BB ends (the operation of one type of BB - A, B, C ends) in "one type of BB - A, B, C", it transitions to "RT1". In addition, when the state regarding AT is in the "low - probability state" and one wins the BB role, and when BB ends, the RT state will transition to "RT1" which is highly profitable for the player. However, since the state regarding AT is a state where the push - order navigator does not occur, when winning the "re - game - D1~D3", if the reels are stopped with an incorrect push - order (the first stop is a 3 - way selection of the left button, middle button, and right button, one of the 3 - way selections is the correct push - order and a re - game other than re - game 04 is stopped and displayed, and 2 of the 3 - way selections are incorrect push - orders and re - game 04 is stopped and displayed), re - game 04 will be stopped and displayed, and it will transition from "RT1" to "RT0". Also, when the state regarding AT is in the "high - probability state", "AT - in state", "specialization precursor state", or "bonus specialization state", if one wins the BB role and BB ends, the RT state will transition to "RT1" which is highly profitable for the player, and at the same time, the state regarding AT is a state where the push - order navigator occurs. Also, when winning the "re - game - D1~D3", since it will guide the correct push - order where re - game 04 is not stopped and displayed, it will be possible to maintain "RT1".

[0108] Next, FIG. 29 is a flowchart of the AT state start control process according to the subroutine of step 1750 in FIG. 18 in the first embodiment. First, at step 1752, the CPU C100 of the main control board M determines whether the conditions for AT state transition are satisfied in the game. The conditions for AT state transition are satisfied, for example, when (1) the setting-free BB that won in the "high probability state" ends, (2) when winning in the continuous lottery, or (3) when winning in the resurrection lottery. If the answer is Yes at step 1752, at step 1754, the CPU C100 of the main control board M, taking the opportunity of newly transitioning to the "pre-AT state", sets the initial AT game number (in this example, 50, which is the number of games from which subtraction starts after transitioning to the "during-AT state") in the AT counter M60 and proceeds to step 1756. Even if the answer is No at step 1752, the process proceeds to step 1756. Next, at step 1756, the CPU C100 of the main control board M determines whether the current state regarding AT is not the high probability state. If the answer is Yes at step 1756, at step 1758, the CPU C100 of the main control board M determines whether the state regarding AT in the next game is the high probability state. If the answer is Yes at step 1758, at step 1760, the CPU C100 of the main control board M sets the high probability guaranteed game number (in this example, 10) in the high probability guarantee counter and proceeds to the next process (the process of step 3500). Even if the answer is No at step 1756 or step 1758, the process proceeds to the next process (the process of step 3500). After winning the BB in the "high probability state" and transitioning to the "advantageous BB internal middle game", when winning the BB and transitioning to the "advantageous BB state", and when the AT game number is added on in the "advantageous BB state", when the BB ends and transitions from the "advantageous BB state" to the "during-AT state", the initial value set in the AT counter will exceed 50. Specifically, when transitioning to the "during-AT state" after the AT game number is added on by 30 games in the "advantageous BB state", 80 (initial value 50 + addition 30) will be set in the AT counter.At this time, when an effect for notifying the player that 30 games have been added in the "advantage BB state" is performed, it is desirable to notify the player that the initial number of AT games is 80 games at the start of the "during AT state". However, as another notification method, deliberately without performing an effect for notifying the player that 30 games have been added in the "advantage BB state", after presenting 50 games, which is the initial value, to the player at the start of the "during AT state", an effect for notifying the player that 30 games have been added during AT (for example, immediately after the start of the "during AT state" or when the remaining number of AT games on the effect display device S40 is small) is also considered as a notification method. By doing so, the player cannot clearly grasp whether the number of AT games has been increased in the "advantage BB state" or how many games have been added, so the interest in the unexpected increase effect that occurs without a clear cause during AT (a state where the push order navigation can occur) can be increased. In this example, the initial number of AT games is set in the AT counter M60 in step 1754, but the execution timing of the process for setting the initial number of AT games is not limited to this example, and the initial number of AT games may be set in the AT counter M60 at the timing of executing the AT state transition control process in step 1400 described above. Also, the number of games (initial number of AT games) set in the AT counter M60 is configured to be subtracted from the start of the game after BB ends (when the state regarding AT becomes the "during AT state") (subtraction does not start during BB). Also, the counter value of the AT counter M60 is configured to be stored in the storage area of the RAM of the main control board M.

[0109] Next, FIG. 30 is an AT state transition diagram in the first embodiment. In the first embodiment, there are 10 states related to ATs, namely, "low probability state", "normal BB internal middle game", "normal BB state", "high probability state", "during AT state", "specialization precursor state", "superimposed specialization state", "advantageous BB internal middle game", "advantageous BB state", and "state for resurrection performance determination". The state related to the AT transitions when the conditions shown by the arrows in the figure are satisfied. For example, when winning on watermelon B in the "during AT state" and winning the specialization state transition lottery with a winning probability of 1 / 2, the state transitions to the "specialization precursor state". Also, when 10 games have elapsed (been completed) after transitioning to the "specialization precursor state", it is configured to transition to the "superimposed specialization state". Note that as game intervals, the states related to the 3 ATs of "low probability state", "normal BB internal middle game", and "normal BB state" are set as the "normal interval", and the states related to the 7 ATs of "high probability state", "during AT state", "specialization precursor state", "superimposed specialization state", "advantageous BB internal middle game", "advantageous BB state", and "state for resurrection performance determination" are set as the "advantageous interval". That is, even if the states related to the 7 ATs that become the "advantageous interval" transition (shift), when 1500 games have elapsed without setting the "normal interval", the "advantageous interval" is forcibly terminated and the "normal interval" is set. Also, when in the notification game state where the push order navigator is displayed, which is the "during AT state", "specialization precursor state", or "superimposed specialization state", even if the replay 04 stops being displayed, the game state is maintained.

[0110] Note that as described above, when in the "during AT state", if the counter value of the AT counter M60 is 0 and the continuous lottery is a non-win, it becomes the "state for resurrection performance determination". If winning the resurrection lottery in the "state for resurrection performance determination", it can return to the "during AT state" again. On the other hand, if not winning the resurrection lottery in the "state for resurrection performance determination", it transitions to the "low probability state", and the "advantageous interval" changes to the "normal interval".

[0111] When winning the no - setting - difference BB (one type of BB - A or one type of BB - C) in the "high - probability state" and the no - setting - difference BB activates and the "favorable BB state" ends, it transitions to the "during - AT state". Also, when winning the no - setting - difference BB (one type of BB - A or one type of BB - C) in the "during - AT state" and the no - setting - difference BB activates and the "favorable BB state" ends, it also transitions to the "during - AT state". In addition, when winning the no - setting - difference BB (one type of BB - A or one type of BB - C) in the "state for resurrection - eligibility performance" and the no - setting - difference BB activates and the "favorable BB state" ends, it also transitions to the "during - AT state" (for winning the resurrection lottery). Further, when winning the BB with a setting difference (one type of BB - B) in the "state for resurrection - eligibility performance" and the BB with a setting difference activates and the "favorable BB state" ends, if the BB with a setting difference is the winning number related to the single BB role (winning number 20), it becomes the "low - probability state" after the BB ends (because it does not win the resurrection lottery triggered by the BB with a setting difference), and if the BB with a setting difference is the winning number overlapping with the rare role (winning numbers 21 - 23), it becomes the "during - AT state" after the BB ends (because it wins the resurrection lottery triggered by the rare role).

[0112] Also, when winning the BB with a setting difference (one type of BB - B) in the "favorable interval" and in the "high - probability state" and the BB with a setting difference activates and the "favorable BB state" ends, it transitions to the "high - probability state".

[0113] Also, regarding the state after the end of the favorable BB state and related to the AT, after the end of the BB won in the during - AT (the "during - AT state", "pre - specialization state", "overlay - specialization state") (regardless of whether it is the BB with a setting difference or the no - setting - difference BB), it transitions to the state related to the AT at the time of BB winning among the "during - AT state", "pre - specialization state" or "overlay - specialization state", and after the end of the no - setting - difference BB won in the non - during - AT (the "high - probability state"), it transitions to the "during - AT state". Also, after the end of the BB with a setting difference won in the non - during - AT (the "high - probability state"), it transitions to the "high - probability state".

[0114] Furthermore, the state regarding the AT is not limited to that of the first embodiment. For example, the AT lottery may be executed by winning a predetermined winning number in a "low probability state" or a "high probability state", and by winning the AT lottery, it may shift to a "precursor state" and shift to an "in-AT state" after 16 to 32 games. When configured in this way, the AT lottery is executed by winning the predetermined conditional device. If not winning the AT lottery, it may shift to a "false precursor state" and shift to a "low probability state" or a "high probability state" after 16 to 32 games. Also, a "waiting interval" different from both the "advantageous interval" and the "normal interval" may be provided as a game interval. For example, when the game property is such that the AT lottery is executed by winning a "cherry", if winning a "BB + cherry" in which BB and cherry overlap and winning the AT lottery, the state inside the BB until the "BB" of the "BB + cherry" wins may be configured as the "waiting interval". In this way, by providing the "waiting interval", when winning the BB in the "low probability state" and not winning the AT lottery, and when winning the BB in the "low probability state" and winning the AT lottery, since the advantageous interval indicator YH is turned off during the period until the symbol combination of the BB is complete (until the advantageous interval indicator lights up), it is possible to encourage the player as to whether or not winning the AT lottery. Also, when winning the BB in the "added-up specialization state", it may be configured to resume the "added-up specialization state" after the end of the BB. When configured in this way, during the BB, a different AT added-up lottery may be executed for the BB won in the "added-up specialization state" than the BB won in the "in-AT state" (for example, it is easier to win the AT added-up lottery than the BB won in the "in-AT state", and the number of games per AT game added-up is relatively large). Also, when winning the BB in the "specialization precursor state", it may be configured to shift to the "added-up specialization state" after the end of the BB. When configured in this way, during the BB, the AT added-up lottery may be executed in the same way as the BB won in the "added-up specialization state".

[0115] Next, FIG. 31 is a flowchart of the game section transition control process according to the subroutine of step 3500 in FIG. 18 in the first embodiment. First, in the first embodiment, there is a game section as a section related to the state of the game. As the game section, there are two game sections: a "normal section" that is relatively less profitable for the player, and an "advantageous section" that is relatively more profitable for the player. As an explanation of the flowchart, first, in step 3508, the CPU C100 of the main control board M determines whether the game section related to the game is the "normal section". If it is Yes in step 3508, in step 3510, the CPU C100 of the main control board M determines the game section for the subsequent games after the next game according to the state related to the current AT and the current game situation, and proceeds to step 3528. On the other hand, if it is No in step 3508, in other words, if the game section is the "advantageous section", in step 3514, the CPU C100 of the main control board M determines whether the counter value of the advantageous section remaining game number counter YKc-1 is 0, in other words, whether the "advantageous section" has reached the maximum number of games that can be continued. If it is Yes in step 3514, in step 3515, the CPU C100 of the main control board M clears all the information related to the AT (thereby, the AT counter value becomes 0, and things like the number of games staying in the "precursor to specialization state" also become 0). On the other hand, if it is No in step 3514, in step 3518, the CPU C100 of the main control board M determines whether any advantageous section end condition is satisfied. Here, any advantageous section end condition is an end condition of the "advantageous section" other than the case where the counter value of the advantageous section remaining game number counter YKc-1 becomes 0, for example, the case where the AT counter value becomes 0, or the case where the push order navigator is executed a predetermined number of times, etc. If it is No in step 3518, that is, if any advantageous section end condition is satisfied, it proceeds to step 3515. Thus, in the first embodiment, when the "advantageous section" ends and is set to the "normal section" for the subsequent games, all the information related to the AT (information related to the AT continuous game number, AT remaining game number, etc.) is cleared, so the conditions for becoming the "advantageous section" again in the subsequent "normal section" are not relaxed.As for the information related to the AT that is cleared by the process of step 3515 (process at the end of the advantageous section), there are the counter value of the remaining game number counter YKc-1 in the advantageous section, the flag indicating the game state, and the like. Also, although these pieces of information will be cleared by the RAM clear at the time of setting change, the information related to the "condition device related to the continuous operation device of accessory (BB)", "RT state", "stored number of coins", etc. will be cleared by the RAM clear at the time of setting change, whereas the information related to the "condition device related to the continuous operation device of accessory (BB)", "RT state", "stored number of coins", etc. will not be cleared by the process of step 3515 (process at the end of the advantageous section). Thus, the RAM clear range at the time of setting change and the clear range at the end of the "advantageous section" (for example, when the process of step 3515 is executed) are different. Incidentally, it may be configured such that the "condition device related to the continuous operation device of accessory (BB)" and the "RT state" are retained by the RAM clear at the time of setting change. Also, the addresses of the range to be cleared at the end of the "advantageous section" are consecutive. By making the addresses of the range to be cleared at the end of the "advantageous section" consecutive in this way, it is possible to perform the clear process with a simple process of designating the start address to be cleared and the range of addresses to be cleared during the clear process. Also, when the "advantageous section" ends, a command indicating that the "advantageous section" has ended is transmitted from the main control board M to the sub-control board S. However, even if the sub-control board S receives the command, it is configured not to erase the game history such as the fact that it was the "advantageous section" or the information related to how many games were executed in the "AT state". However, when the RAM clear at the time of setting change is executed, the game history such as the fact that it was the "advantageous section" or the information related to how many games were executed in the "AT state" on the sub-control board S side will also be erased.

[0116] When the "advantageous section" ends because the counter value of the remaining game number counter YKc-1 in the advantageous section becomes 0, (1) if the state regarding the current AT is the "high probability state", the state regarding the AT in the next game becomes the "low probability state", (2) if the state regarding the current AT is the "advantageous BB internal middle game", the state regarding the AT in the next game becomes the "normal BB internal middle game", (3) if the state regarding the current AT is the "advantageous BB state", the state regarding the AT in the next game becomes the "normal BB state", (4) if the state regarding the current AT is the "during AT state", "precursor specialization state", "added-on specialization state", or "state for resurrection confirmation effect", the state regarding the AT in the next game becomes the "low probability state" (because the information related to the AT is cleared).

[0117] Next, in step 3516, the CPU C100 of the main control board M sets the game section after the next game as the "normal section". Next, in step 3517, the CPU C100 of the main control board M turns off the advantageous section indicator YH because the "advantageous section" has ended, and proceeds to step 3528. Although it is configured to turn off the advantageous section indicator YH when the "advantageous section" ends and the "normal section" is set, the detailed timing of turning off is not limited to the timing of the first embodiment. For example, it may be configured to turn off the advantageous section indicator YH when game medals related to the game in which the "advantageous section" ends and the "normal section" is entered are inserted. In other words, it suffices to configure it to turn off the advantageous section indicator YH before the start lever D50 for starting the next game is operated. On the other hand, if it is Yes in step 3518, in step 3520, the CPU C100 of the main control board M determines that the game section after the next game is the "advantageous section", and proceeds to step 3528.

[0118] Next, in step 3528, the CPU C100 of the main control board M determines whether it has been decided to newly set a "favorable section" in the next game (it has been decided to set from the "normal section" to the "favorable section"). If Yes in step 3528, in step 3530, the CPU C100 of the main control board M sets a predetermined value in the remaining game count counter YKc-1 for the favorable section. Note that the predetermined value set in the remaining game count counter YKc-1 for the favorable section is a fixed numerical value common to all setting values (in this example, 1500). Next, in step 3534, the CPU C100 of the main control board M lights up the favorable section indicator YH and proceeds to the next process (the process of step 1293). Note that even if No in step 3528, it also proceeds to the next process (the process of step 1293). Note that in the first embodiment, the lighting process of the favorable section indicator YH is executed at the timing of step 3534, but the lighting timing of the favorable section indicator YH is not limited to this. The lighting timing of the favorable section indicator YH may be appropriately set within the period from the operation timing of the start lever in the game before the new "favorable section" (the game in the "normal section") to the timing when game medals can be inserted in the game when the new "favorable section" is reached (if the game before the new "favorable section" is a game related to a replay, up to the timing when the operation of the start lever in the game when the new "favorable section" is reached becomes effective).

[0119] Next, FIG. 32 is a flowchart of the process at the time of timer interruption related to the subroutine of step 1600 in the first embodiment. The process of the subroutine starts to be executed when a timer interruption is started in the process of step 1040 or step 1104, and thereafter, it is configured to be periodically executed at a predetermined time interval (in this example, set as T, but for example, a time of about 2 ms is set).

[0120] First, in step 1602, the CPU C100 of the main control board M executes processing at the start of the interruption (for example, saving data held in registers within the CPU C100, checking the input port of the power-off detection signal, etc.). Next, in step 1604, the CPU C100 of the main control board M determines whether power-off is not currently detected (in this interruption process). If the result in step 1604 is No, in step 1900, the CPU C100 of the main control board M executes the power-off time processing described later. On the other hand, if the result in step 1604 is Yes, in step 1606, the CPU C100 of the main control board M starts timer measurement (update processing of various timers managed by software). Next, in step 1608, the CPU C100 of the main control board M generates input port data and stores the data (updates the storage area of each input port data within the RAM area). Here, the input port data is information related to the detection of the settlement button D60, start lever D50, stop button D40, door switch D80, setting key switch M20, setting / reset button M30, power-off detection signal, insertion acceptance sensor D10s, first insertion sensor D20s, second insertion sensor D30s, first payout sensor H10s, second payout sensor H20s, etc. (that is, the presence or absence of operations on these operation members and the sensor detection state are sampled at the interruption interval T).

[0121] Next, in step 1610, the CPU C100 of the main control board M refers to the input port data in the RAM area, and switches the on / off states of the door switch flag and the setting key switch flag according to the sampling results of the respective input port data (for example, when the switch state of the door switch D80 is continuously on over multiple samplings, the door switch flag can be turned on to detect that the front door DU is in the open state without being affected by noise). Next, in step 6100, the CPU C100 of the main control board M executes the turning cylinder drive control process for all reels (left reel M51, middle reel M52, right reel M53) (this is the process related to the control of the drive of the reel M50, and the details will be described later). Next, in step 1612, the CPU C100 of the main control board M refers to the AT counter M60 and determines whether the counter value is greater than 0. If Yes in step 1612, in step 1613, the CPU C100 of the main control board M displays the remaining AT game number (AT game number) on the AT counter value display device D280 and proceeds to step 1614. Incidentally, even if No in step 1612, it also proceeds to step 1614. Incidentally, when the main control board M does not include the AT counter value display device D280 controlled thereby, the processes of step 1612 and step 1613 are unnecessary. Next, in step 1614, the CPU C100 of the main control board M outputs the output data to the output port. Here, the output data is data for driving the reel M50, the blocker D100, etc. Next, in step 1616, the CPU C100 of the main control board M determines whether all error flags are off (not shown, but all flags related to errors such as the inserted medal reverse flow error flag, the inserted number error flag, the inserted medal retention error flag, the inserted abnormality error flag, the payout abnormality error flag, the payout medal retention error flag, the door switch flag, etc. are off). If Yes in step 1616, in step 1618, the CPU C100 of the main control board M sets an error undetected command (a command to the sub-side, a command related to the fact that no error has been detected) (for example, set it in the register area) and proceeds to step 1622.On the other hand, if the answer is "No" in step 1616, in step 1620, the CPU C100 of the main control board M sets an error detection command (a command to the sub-side indicating that an error has been detected) (for example, sets it in the register area), and proceeds to step 1622. Note that in step 1620, information related to the error corresponding to the error flag that is on (the currently occurring error) is configured to be transmitted to the sub-side. Also, the error non-detection command may be set only when the error is released from the state where the error occurred (only when it is determined that the flag has been turned off), or the setting process of the said information may not be executed when no error is detected (step 1618 may be omitted). Furthermore, the error detection command may execute the setting process only when an error occurs from the state where no error occurred, or may execute the setting process when the type of error changes, such as from the occurrence of a first error (for example, inserted medal retention error) to the occurrence of a second error (for example, paid-out medal retention error).

[0122] Next, in step 1622, the CPU C100 of the main control board M transmits a control command (sub-side command) (for example, if it is set in the register area in steps 1618 or 1620, the set control command will be transmitted). Here, as commands to be transmitted to the sub-control board S, there are commands related to the start lever operation timing (transmitted immediately after the start lever is operated), commands related to the first reel stop reception timing (transmitted immediately after the stop button is operated as the first stop), commands related to the second reel stop reception timing (transmitted immediately after the stop button is operated as the second stop), commands related to the third reel stop reception timing (transmitted immediately after the stop button is operated as the third stop), commands transmitted immediately after all reels stop, commands related to the stop timing of the stop display symbol (transmitted immediately after the stop button is operated as the display symbol stop), commands related to winning and replay winning information (transmitted immediately after the start lever is operated (only within the advantageous section)), commands related to bonus winning information (transmitted immediately after the start lever is operated), commands related to the RT state (transmitted between when all reels stop and the next game starts), commands related to the state regarding AT (transmitted between when all reels stop and the next game starts), high-security counter value commands (transmitted immediately after the start lever is operated), commands related to the remaining number of AT games (transmitted between when all reels stop and the next game starts, or immediately after the start lever is operated), commands related to the game section (transmitted between when all reels stop and the next game starts), etc. Next, in step 1624, the CPU C100 of the main control board M outputs an external terminal signal (a signal for transmitting information from the rotary gaming machine P to an external hall computer, etc.). Incidentally, although not shown, information related to errors output by the external signal includes door open error, insertion abnormality error, payout abnormality error, insertion reception sensor retention error, etc. The door open error is configured to be an error when the front door DU is opened and the door switch flag is on, and the insertion reception sensor retention error is configured to be an error when the insertion reception sensor detects the retention of gaming medals.Next, in step 1626, the CPU C100 of the main control board M outputs output data of an LED (such as a 7-segment LED lamp, etc.) (for example, among a plurality of 7-segment LED units, a predetermined 7-segment LED unit is lit and a predetermined segment of the 7 segments is lit) (so-called dynamic lighting). Next, in step 1628, the CPU C100 of the main control board M executes a lighting mode of the LED (for example, changes the lighting color of the LED). Note that step 1628 may not be executed. Next, in step 1630, the CPU C100 of the main control board M executes a software random number management process (such as an update process of a random number value managed by software). Next, in step 1632, the CPU C100 of the main control board M acquires internal information register data (there is an area in the internal information register where an abnormal flag bit is set when an abnormality occurs in the random number generation circuit). Next, in step 1634, the CPU C100 of the main control board M determines whether the frequency of the clock for random number update is normal (whether an abnormal flag bit indicating the frequency abnormality is set or not). Specifically, an abnormal flag bit is set when the frequency of the clock for random number update is lower than a predetermined value. If Yes in step 1634, in step 1636, the CPU C100 of the main control board M determines whether the update state of the built-in random number is normal (whether an abnormal flag bit indicating the update state abnormality is set or not). If Yes in step 1636, in step 1638, the CPU C100 of the main control board M executes an interrupt end process and transfers to the next process (the process of step 1602). On the other hand, if No in step 1634 or step 1636, in step 1640, the CPU C100 of the main control board M sets a built-in random number error display (for example, sets an error number in the register area). Next, in step 1300, the CPU C100 of the main control board M executes the above-described non-returnable error process.

[0123] Next, FIG. 33 is a flowchart of the drum drive control process according to the subroutine of step 6100 in FIG. 32 in the first embodiment. Note that, in this process, the process for one reel is illustrated, but it should be supplemented that the processes corresponding to the left reel M51, the middle reel M52, and the right reel M53 are executed. First, in step 6102, the CPU MC of the main control board M determines whether the timing for starting to wait for the reel rotation to start (for example, the timing after the execution of the process in step 1564 in FIG. 25) has been reached. If Yes in step 6102, in step 6104, the CPU MC of the main control board M updates the reel drive state to the reel rotation start waiting state and proceeds to step 6106. On the other hand, even if No in step 6102, the process proceeds to step 6106.

[0124] Next, in step 6106, the CPU MC of the main control board M determines whether the timing for starting the reel acceleration state (the timing when the reel rotation start waiting state ends and the acceleration process of the reel starts to be executed, for example, the execution timing of the process in step 1260 in FIG. 18) has been reached. If Yes in step 6106, in step 6108, the CPU MC of the main control board M updates the reel drive state to the reel acceleration state. Next, in step 6110, the CPU MC of the main control board M executes the reel acceleration process and proceeds to step 6112. Note that when the reel is stopped, the rotation of the reel will start by this process. On the other hand, even if No in step 6106, the process proceeds to step 6112.

[0125] Next, in step 6112, the CPU MC of the main control board M determines whether the current reel driving state is the reel acceleration state. If Yes in step 6112, in step 6114, the CPU MC of the main control board M determines whether the end timing of the reel acceleration state (for example, the timing when all the interrupt processes for the "number of interrupt executions" in the reel acceleration state in FIG. 35 described later have been executed) has been reached. If Yes in step 6114, in step 6116, the CPU MC of the main control board M updates the reel driving state to the reel constant speed state. Next, in step 6118, the CPU MC of the main control board M executes the reel constant speed maintenance process and proceeds to step 6120. Incidentally, even if No in step 6112 or step 6114, the process proceeds to step 6120.

[0126] Next, in step 6120, the CPU MC of the main control board M determines whether the current reel driving state is the reel constant speed state. If it is Yes in step 6120, then in step 6122, the CPU MC of the main control board M determines whether the reel sensor has detected the index provided on the reel (the reel corresponding to the processing of this subroutine) since the reel constant speed state (since the processing of step 6116 was executed). Here, although not shown in the figure, each reel is provided with one (or two or more) index. The index is provided convexly on, for example, the circumferential side surface of the reel and is used when detecting whether the reel has passed a predetermined position, whether it has rotated once, etc. And each index is detected by the reel sensor. The signal of the reel sensor is electrically connected to the main control board M. And when the reel sensor detects (cuts) the index, its input signal is input to the main control board M, and it is configured such that it is detected that the reel has passed a predetermined position. If it is Yes in step 6122, it is determined that the rotation speed of the reel has become constant speed, and the process proceeds to the process of step 6130. On the other hand, if it is No in step 6122, then in step 6124, the CPU MC of the main control board M determines whether a predetermined time (for example, the time value for executing the interrupt process 400 times) has elapsed since the reel driving state became the reel constant speed state. If it is No in step 6124, it is determined that the rotation speed of the reel has become constant speed, and the process proceeds to the process of step 6130. Thus, in this example, it is configured such that it is possible to determine whether the reel rotation speed has become normally constant speed by the reel sensor detecting the index within a predetermined time since the reel driving state became the reel constant speed state. Incidentally, the predetermined time in this example is the time value for executing the interrupt process 400 times (configured such that it can rotate 400 steps with 400 interrupt processes), and it is longer than the time (for example, one rotation of the reel is 336 steps, and the time value for executing the interrupt process 336 times) when the reel rotates once (one circumference) when the reel rotation speed is constant speed.By configuring in this way, no matter how far the distance between the index and the reel sensor is at the timing when the reel driving state becomes the constant speed state (the distance until the index is detected by the reel sensor as the reel rotates), when the reel rotation speed is constant, the reel sensor can detect the index within the predetermined time (the time value for executing the interrupt process 400 times) after the reel driving state becomes the reel constant speed state.

[0127] Returning to the description of the flowchart, if Yes in step 6124, in step 6126, the CPU MC of the main control board M updates the reel driving state to the reel acceleration state. Next, in step 6128, the CPU MC of the main control board M executes the reel re-acceleration process and proceeds to the process of step 6130. Thus, in this example, if the reel sensor does not detect the index within a predetermined time (for example, the time value for executing the interrupt process 400 times) after the reel driving state becomes the reel constant speed state, the reel driving state is updated to the reel acceleration state again, and the reel re-acceleration process (the excitation mode of the stepping motor is the same as that of the reel acceleration process) is configured to be executed. Still, even if No in step 6120, the process proceeds to the process of step 6130. Still, the reel re-acceleration process does not necessarily have to be the same process as the aforementioned reel acceleration process, and the combination of phases to be excited by the stepping motor and the number of times of executing the interrupt process for each combination of phases to be excited may be made different between the reel re-acceleration process and the reel acceleration process.

[0128] Next, FIG. 34 is a flowchart of the reel rotation stop process related to the subroutine of step 6200 in FIG. 32 in the first embodiment. First, in step 6106, the CPU MC of the main control board M determines whether or not it has reached the reel deceleration standby state start timing (which is the timing when the reel constant speed state ends, for example, it is determined that the reel deceleration standby state start timing has occurred when the stop button is operated). If Yes in step 6130, in step 6132, the CPU MC of the main control board M updates the reel drive state to the reel deceleration standby state and proceeds to step 6134. On the other hand, even if No in step 6130, it also proceeds to step 6134.

[0129] Next, in step 6134, the CPU MC of the main control board M determines whether the current reel drive state is the reel deceleration standby state. If Yes in step 6136, the CPU MC of the main control board M determines whether or not it has reached the reel deceleration standby state end timing (the timing to start executing the reel deceleration process). If Yes in step 6136, in step 6138, the CPU MC of the main control board M starts the deceleration of the reel (reel deceleration process). Next, in step 6140, the CPU MC of the main control board M updates the reel drive state to the reel deceleration state and proceeds to the process of step 6142. Note that even if No in step 6134 or step 6136, it also proceeds to the process of step 6142.

[0130] Next, in step 6142, the CPU MC of the main control board M determines whether the current reel drive state is the reel deceleration state. If Yes in step 6142, in step 6144, the CPU MC of the main control board M determines whether or not it has reached the reel deceleration state end timing (the timing to end the execution of the reel deceleration process). If Yes in step 6144, in step 6146, the CPU MC of the main control board M updates the reel drive state to the reel stop state and proceeds to the next process (the process of step 1612). Note that even if No in step 6142 or step 6144, it also proceeds to the next process (the process of step 1612).

[0131] Next, with reference to FIG. 35, the rotation operation of the reel M50 of the rotary gaming machine according to this example will be described in detail. The rotary gaming machine according to this example starts the rotation of the stepping motor based on the operation of the start lever D50, and when the rotation speed of the reel reaches a constant speed, hereinafter, it maintains the constant speed (when the reel driving state becomes the reel constant speed state, the reel constant speed maintenance process is executed, but there may be cases where the rotation speed has not actually reached the constant speed). Then, when any stop button is operated, stop control is performed on the reel (stepping motor) corresponding to the operated stop button. Here, the stepping motor is a four-phase stepping motor having four phases Φ0, Φ1, Φ2, Φ3 (it doesn't matter if it's not a four-phase stepping motor), and rotation control is performed by switching the phases to be excited and exciting the stepping motor in 1-2 phases. That is, the stepping motor can be rotated in the forward direction by cyclically changing the drive pulse data (the combination of phases to be excited). In the figure, among Φ0 to Φ3, what indicates which phase is to be excited is shown in the column of "phase to be excited" (details will be described later).

[0132] Also, as shown in the "reel rotation speed image" in the upper part of the figure, the driving state from when the stepping motor starts rotating until it stops is divided into six states, and the stepping motor is driven and controlled according to the drive pattern corresponding to each driving state. Here, the driving states include "reel stop state", "reel rotation start standby state", "reel acceleration state", "reel constant speed state", "reel deceleration standby state", and "reel deceleration state". Note that in the "reel rotation speed image", the vertical axis represents the reel rotation speed and the speed increases upward, and the horizontal axis represents time and the time elapses to the right. Also, an example shown in the figure illustrates the case where no reel rotation failure occurs. This is not the case when a reel rotation failure occurs due to factors such as holding the reel by hand or out-of-tune (the case of reel rotation failure will be described later).

[0133] The "reel stop state" indicates the state in which the reel has stopped. When in the "reel stop state", the reel is in a stationary state and all four phases of the stepping motor are not energized.

[0134] Next, in the situation of the "reel stop state", based on the operation of the start lever D50 at the timing of (1) in the figure, the reel drive state is updated to the "reel rotation start standby state". Here, the "reel rotation start standby state" indicates the state of waiting until the acceleration process (reel acceleration process) of the stepping motor is started after the start lever D50 is operated. This waiting period is the period until the reel drive state transitions from the "reel stop state" to the "reel acceleration state". For example, if the time since the drive state of the reel became the "reel acceleration state" in the previous game is measured, and the start lever D50 related to this game is operated before the minimum game time (about 4.1 seconds) has elapsed, the "reel rotation start standby state" is entered.

[0135] Next, at the timing of (2) in the figure, the reel drive state is updated from the "reel rotation start standby state" to the "reel acceleration state". Here, the "reel acceleration state" is a state in which the reel is being accelerated to reach a constant speed from a stationary state. In this example, when the timer interrupt process is executed 220 times ("100 + 60 + 30 + 15 + 8 + 4 + 2 + 1 = 220", refer to the number of interrupt executions in the reel acceleration state at the lower left of the figure), the acceleration state ends (the reel drive state is updated to the "reel constant speed state"). Next, at the timing of (3) in the figure, in other words, at the timing when the "reel acceleration state" ends by executing the timer interrupt process one more time, the reel rotation speed reaches a constant speed. Note that at this timing, the reel drive state remains in the "reel acceleration state". Next, at the timing of (4) in the figure, after the reel drive state is updated from the "reel rotation start standby state" to the "reel acceleration state", since the timer interrupt process has been executed 220 times, the reel drive state is updated to the "reel constant speed state". In this way, in this example, after the reel rotation speed reaches a constant speed, for one timer interrupt process, the reel drive state remains in the "reel acceleration state". In other words, for the combination of phases "φ3, φ0", which is the combination of the last excited phases in the "reel acceleration state", the interrupt process is configured to be executed only once, and it has the same excitation mode as the "reel constant speed state" in which the interrupt process is executed once for each combination of excited phases (when no abnormal rotation of the reel occurs). By configuring it in this way, the acceleration process until the reel rotation speed reaches a constant speed can be stably executed.

[0136] Here, the lower part of the figure is the "step motor excitation image". In this figure, the step motor excitation image when the reel driving state is the "reel acceleration state" and the step motor excitation image when the reel driving state is the "reel constant speed state" are exemplified. First, the step motor excitation image when the reel driving state is the "reel acceleration state" will be described in detail with reference to the lower left part of the figure. Note that the "phase to be excited" is a combination of phases to be excited, and the "number of interrupt executions" indicates the number of times the interrupt process that will be excited with that combination of phases to be excited is executed. In this example, when executing the reel acceleration process, the step motor (stepping motor) is configured to be excited for 220 times of timer interrupt processing, (KA) the interrupt process is executed 100 times at "φ0" → (KB) the interrupt process is executed 60 times at "φ0, φ1" → (KC) the interrupt process is executed 30 times at "φ1" → (KD) the interrupt process is executed 15 times at "φ1, φ2" → (KE) the interrupt process is executed 8 times at "φ2" → (KF) the interrupt process is executed 4 times at "φ2, φ3" → (KG) the interrupt process is executed 2 times at "φ3" → (KH) the interrupt process is executed 1 time at "φ3, φ0", and it is configured to excite the step motor (stepping motor) by executing the interrupt process in this way (the number of interrupt executions is just an example and can be changed without problem). Thus, in this example, when executing the reel acceleration process, it is configured to gradually decrease the number of times the interrupt process is executed with one combination of phases to be excited.

[0137] Next, the step motor excitation image when the reel driving state is the "reel constant speed state" will be described in detail with reference to the lower right part of the figure. In this example, when in the reel constant speed state (when executing the reel constant speed maintenance process), (TA) an interrupt process is performed once at "φ0" → (TB) an interrupt process is performed once at "φ0, φ1" → (TC) an interrupt process is performed once at "φ1" → (TD) an interrupt process is performed once at "φ1, φ2" → (TE) an interrupt process is performed once at "φ2" → (TF) an interrupt process is performed once at "φ2, φ3" → (TG) an interrupt process is performed once at "φ3" → (TH) an interrupt process is performed once at "φ3, φ0" → (TA) an interrupt process is performed once at "φ0" → (TB) an interrupt process is performed once at "φ0, φ1" → ···, and so on. (TA) to (TG) are repeatedly executed once each for the interrupt process to excite the step motor (stepping motor). Thus, in this example, when executing the reel constant speed maintenance process, the number of times the interrupt process is executed for each combination of the excited phases is configured to be 1 time each.

[0138] Next, in a situation where the reel driving state is the "reel constant speed state", at the timing of (5) in the figure, a stop button corresponding to any one of the reels is operated, and the reel driving state is updated to the "reel deceleration standby state". Here, the "reel constant speed state" is a state where the rotation speed of the reel is constant (a state where the combination of the excited phases is switched for each interrupt process), and the "reel deceleration standby state" is a state from when the stop button is operated by the player until the start of the stop control (in the reel deceleration standby state, the slip of the reel corresponding to the number of slip frames occurs). The period of this driving state is determined based on the operation timing of the stop button.

[0139] Next, at the timing of (6) in the figure, the reel driving state is updated from the "reel deceleration standby state" to the "reel deceleration state", and the deceleration of the reel is started. When the reel driving state is updated from the "reel deceleration standby state" to the "reel deceleration state", a specific phase of the stepping motor is continuously excited for a predetermined time to stop the rotation of the reel. As an example, 4-phase excitation in which all 4 phases are excited is performed. Then, when the excitation is performed for a predetermined time, at the timing of (7) in the figure, the reel driving state is updated from the "reel deceleration state" to the "reel stop state", and the reel stops.

[0140] As described above, in the rotating drum gaming machine according to this example, when the reel sensor does not detect an index within a predetermined time (for example, the time value for executing the interrupt process 400 times) after the reel driving state becomes the reel constant speed state, the reel driving state is updated to the reel acceleration state again, and the reel re-acceleration process (the excitation mode of the stepping motor is the same as that of the reel acceleration process) is configured to be executed. Therefore, when the reel driving state is the reel acceleration state, in other words, during the execution of the reel acceleration process, it is not determined whether the acceleration of the reel is normally executed. Further, whether the acceleration of the reel is normally performed, in other words, whether the reel has reached a constant speed (whether there is no reel rotation failure) is determined by the process of step 6124 (determined after a predetermined time has elapsed since the reel driving state was updated to the reel constant speed state). However, in the process of step 6124, if it is determined that the reel has not reached a constant speed (a reel rotation failure has occurred) because the reel sensor did not detect an index, the reel re-acceleration process is executed, that is, the reel acceleration process is configured to be executed again from the beginning. In this way, by configuring not to determine whether the acceleration of the reel is normally executed during the execution of the reel acceleration process, even if a reel rotation failure occurs during the execution of the reel acceleration process, and then the reel rotation failure is eliminated, and the remaining reel acceleration process until the execution of the reel acceleration process is completed can reach the constant speed of the reel rotation speed, the reel sensor detects an index before a predetermined time elapses after the reel driving state is updated to the reel constant speed state, so that the reel constant speed maintenance process is executed without executing the re-acceleration process, and it is possible to make it difficult for a situation where the player cannot proceed with the game (cannot operate the stop button) to occur due to the execution of the reel re-acceleration process. Further, by configuring not to execute a process for determining whether the acceleration of the reel is normally executed during the execution of the reel acceleration process, the amount of data required for the process related to the rotation of the reel can be reduced. Since it is configured in this way, when a reel rotation failure occurs while the rotating drum gaming machine according to this example is executing the reel acceleration process, it will act as follows.

[0141] <Function 1> Rotation of the reel starts → Update the reel drive state to the reel acceleration state → Execute the reel acceleration process → End of execution of the reel acceleration process → Update the reel drive state to the reel constant speed state → Execute the reel constant speed maintenance process → Reel rotation failure occurs during the execution of the reel constant speed maintenance process → Detect the reel rotation failure → Execute the reel re-acceleration process It is configured to be able to act as described above. Note that the reel rotation failure refers to the case where the rotation of the reel is inhibited by a member provided near the reel such as the reel window D160 (e.g., the reel rubs against the reel window D160), or out-of-tune occurs, etc., and the acceleration of the reel is not executed normally. In this way, by configuring to execute the reel re-acceleration process even when a reel rotation failure occurs during the execution of the reel constant speed maintenance process, the game can proceed smoothly.

[0142] <Function 2> Rotation of the reel starts → Update the reel drive state to the reel acceleration state → Execute the reel acceleration process → Reel rotation failure occurs during the execution of the reel acceleration process → Continue to execute the reel acceleration process → End of execution of the reel acceleration process → Update the reel drive state to the reel constant speed state → Execute the reel constant speed maintenance process → Detect the reel rotation failure → Execute the reel re-acceleration process It is configured to be able to act as described above. In this way, by configuring to execute the reel re-acceleration process when a reel rotation failure is detected after a reel rotation failure occurs during the execution of the reel acceleration process, the game can proceed smoothly. Also, as described above, even when a reel rotation failure occurs during the execution of the reel acceleration process, continue to execute the reel acceleration process, and end the execution of the reel acceleration process when the reel acceleration process is executed for the same number of interruptions as when no reel rotation failure occurs. By configuring in this way, it is possible to configure such that the rotational speed of the reel easily reaches a constant speed without executing the reel re-acceleration process when a reel rotation failure occurs immediately after the start of execution of the reel acceleration process.

[0143] <Function 3> The rotation of the reel starts → the reel driving state is updated to the reel acceleration state → the reel acceleration process is executed → the power-off process is executed during the execution of the reel acceleration process → the power is restored → the reel acceleration process is continued to be executed (the unprocessed reel acceleration process is executed) → a reel rotation failure occurs during the execution of the reel acceleration process → the reel acceleration process is continued to be executed (the unprocessed reel acceleration process is executed) → the execution of the reel acceleration process ends → the reel driving state is updated to the reel constant speed state → the reel constant speed maintenance process is executed → a reel rotation failure is detected → the reel re-acceleration process is executed It is configured to be able to act as described above. Thus, even when the power-off process is executed during the execution of the reel acceleration process, after the power is restored, the reel acceleration process is continuously executed, and then, if the reel sensor does not detect the index within a predetermined time after updating the reel driving state to the reel constant speed state, the reel re-acceleration process is executed, so that the game can proceed smoothly. Also, when the power-off process is executed during the execution of the reel acceleration process, if the reel sensor detects the index within a predetermined time after the power is restored and the reel acceleration process is continuously executed and then the reel driving state is updated to the reel constant speed state, the reel re-acceleration process is not configured to be executed. By configuring it in this way, it is possible to make it difficult for a situation where the player cannot proceed with the game (cannot operate the stop button) due to the reel re-acceleration process to occur. Note that the power-off process may be referred to as the power-off time process.

[0144] <<Action after operating the final stop button>> The rotating type gaming machine according to this example is configured such that when the final reel (the reel that rotates until the end and is also referred to as the third reel) stops after the operation of the final stop button (the third stop button), and the symbol combination that becomes the winning combination stops and is displayed, the payout of game medals can be executed. However, as an action regarding the payout of game medals, it may be configured as follows.

[0145] <Action 1> As a game that wins a winning role, the rotation of the reels starts → the reel driving state is updated to a constant speed state → the constant speed state maintenance process is executed → the reception of the stop button becomes effective → the first stop button is operated as the stop operation of the first reel → the first reel stops and is displayed → the second stop button is operated as the stop operation of the second reel → the second reel stops and is displayed → the third stop button is operated as the stop operation of the third reel (the operation of the third stop button is received) → the reel driving state is updated to the reel deceleration state → a power failure occurs → the third reel moves (rotates) to the stop display position → a power failure is detected → the power failure time process is executed → the power is restored → the symbol combination corresponding to the winning role is stopped and displayed on the reel → the process related to the payout of the game medals is executed It may be configured to act as described above. By configuring in this way, in the game that wins a small role that can be won regardless of the operation timing of the stop button when winning a common bell or the like described above, even when a power failure occurs due to a power outage at the game arcade immediately after receiving the stop operation of the third stop button, regardless of the planned stop position of the third reel (even when the number of sliding frames is the maximum), it can be configured so that the movement (rotation) to the planned stop position is completed before detecting the power failure. Further, when the symbol combination (for example, a common bell) constituting the winning role is stopped and displayed after the power is restored, the payout of the game medals can be executed normally, and it can be configured so that it is difficult for the player to suffer disadvantages.

[0146] <Operation 2> As a game that has won a winning combination, the rotation of the reels starts → the reel driving state is updated to a constant speed state → the constant speed state maintenance process is executed → the reception of the stop button becomes effective → the first stop button is operated as the stop operation of the first reel → the first reel stops and is displayed → the second stop button is operated as the stop operation of the second reel → the second reel stops and is displayed → the third stop button is operated as the stop operation of the third reel (the operation of the third stop button is received) → the reel driving state is updated to the reel deceleration state → a reel rotation failure occurs → the third reel cannot move (rotate) to the stop position as seen by the player → although the symbol combination corresponding to the winning combination is not stopped and displayed on the reel as seen by the player, in the determination process of step 1269, it is determined that the symbol combination is normal (this is the case where it is determined that the stop control of the reel based on the operation of the stop button has been completed normally. For example, in a game where the bell combination has won, although the symbol combination corresponding to the bell combination, which is the winning combination, is not stopped and displayed on the reel as seen by the player, the stop control for causing the symbol combination corresponding to the bell combination to be stopped and displayed is executed normally by the internal processing of the gaming machine corresponding to the player's operation of the stop button) → the process related to the payout of the gaming medals is executed It may be configured to operate as described above. By configuring it in this way, even if a reel rotation failure occurs immediately after receiving the stop operation of the third stop button and the symbol combination corresponding to the winning combination is not stopped and displayed on the reel as seen by the player, the internal processing of the gaming machine wins the winning combination, and the operation of the stop button corresponding to each reel (left reel, middle reel, right reel) is received at a timing when the symbol combination corresponding to the winning combination can be stopped and displayed. When the stop control for stopping and displaying the symbol combination corresponding to the winning combination is executed normally, the payout of game medals can be executed, and it can be configured so that it is difficult for the player to suffer disadvantages. Note that the timing at which the reel rotation failure occurs is not limited to the above example. If a reel rotation failure occurs during the period from when the second reel stops and is displayed until the process related to the payout of game medals is executed, and as a result, the reel corresponding to the third stop cannot stop at the stop planned position, all of these cases are applicable (also applicable to the operations related to the reel rotation failure exemplified below). Note that in the above operation 2, the operation in the game that wins the winning combination is exemplified. That is, when no reel rotation failure occurs, the following operations are performed (in other operations, when no rotation failure or power failure occurs, it may be configured to perform the same operations). As a game that wins the winning combination, the rotation of the reel starts → the reel drive state is updated to a constant speed state → the constant speed state maintenance process is executed → the reception of the stop button becomes effective → the first stop button is operated as the stop operation of the first reel → the first reel stops and is displayed → the second stop button is operated as the stop operation of the second reel → the second reel stops and is displayed → the third stop button is operated as the stop operation of the third reel (the operation of the third stop button is received) → the reel drive state is updated to the reel deceleration state → the third reel moves to the stop planned position as seen by the player → the symbol combination corresponding to the winning combination is stopped and displayed on the reel as seen by the player, and in the determination process of step 1269, it is determined that the symbol combination is normal → the process related to the payout of game medals is executed Furthermore, as a winning combination in the above-described or below-described operation, it may be a winning combination (e.g., common bell) that can win regardless of the operation timing of the stop button in the selected game, or a winning combination (e.g., watermelon A, watermelon B, cherry) that may or may not win depending on the operation timing of the stop button in the selected game. Also, in a game in which a predetermined winning combination is won in a predetermined gaming state, when a reel rotation failure or power failure does not occur and the symbol combination corresponding to the predetermined winning combination stops and is displayed, a backlight (sometimes referred to as a backlamp) of the reel blinks (sometimes referred to as a backlamp effect), and when configured to execute the backlamp effect corresponding to the predetermined winning combination, even when a reel rotation failure occurs in the game in which the predetermined winning combination is won in the predetermined gaming state and the symbol combination corresponding to the predetermined winning combination does not stop and is displayed, it may be configured to execute the backl...
