Description

The present invention relates to a gaming machine that determines by lottery whether or not to award a gaming advantage to a player.

In a slot machine used as a gaming machine, a winning combination is drawn in response to the player's bet of medals (gaming media) and the operation of a start switch, and multiple reels marked with various symbols spin. The reels are then stopped sequentially in response to the results of the lottery and the player's operation of a stop switch, and when a symbol combination corresponding to a winning combination is displayed on a pay line, which is the line that is eligible for payout, a predetermined number of medals is paid out, and a gaming profit (hereinafter simply referred to as gaming profit) is awarded to the player.

In addition, in slot machines, multiple game states are provided that give players different degrees of advantage (game profits) during gameplay. For example, when a winning combination with a large game profit (hereinafter referred to as a correct combination) overlaps with another winning combination (hereinafter referred to as a selected winning type), the operation mode of the stop switch that is the winning condition for the correct combination (hereinafter referred to as a correct operation mode) is notified (hereinafter, the performance that notifies the operation mode that is the winning condition for such a predetermined winning combination (assisting the winning of the correct combination) is simply referred to as an assist performance), and some slot machines are provided with an AT performance state in which an AT (assist time) is executed, allowing the player to easily display the symbol combination corresponding to the correct combination on the pay line. In addition, some slot machines use an RT (replay time) game state in which the winning probability of a replay role is set high, or a so-called ART game state in which the above-mentioned AT performance state and the RT game state proceed simultaneously (for example, Patent Document 1).

JP 2011-010751 A

In slot machines, the expected number of coins to be won per unit of play in the AT performance state can be set as desired. For example, by increasing the expected number of coins to be won per unit of play in the AT performance state, the player can obtain a large gaming profit in a short period of time, which increases the player's motivation to play.

However, if the expected number of coins to be won per unit of play in the normal presentation state is set relatively low in order to increase the expected number of coins to be won per unit of play in the AT presentation state, the player's investment will be unnecessarily large. On the other hand, if one tries to prevent a decrease in the expected number of coins to be won per unit of play in the normal presentation state, one has no choice but to set the probability of transitioning to the AT presentation state low or to set a period during which no lottery is held. This will result in a decrease in the frequency of transitions to the AT presentation state, which could lead to players feeling bored.

In view of these problems, the present invention aims to provide a gaming machine that can improve playability while maintaining the player's motivation to play.

In order to solve the above problem, the gaming machine of the present invention includes a winning type lottery means for determining, by lottery, one of a plurality of winning types including a selected winning type (e.g., a winning type "batting order chance role B1") in which a first role (e.g., winning roles "small role 33" and "small role 34") overlaps with a second role (e.g., winning role "small role 1") having a larger payout amount than the first role, and the first role can be won by a first operation and the second role can be won by a second operation; a reel control means for controlling the rotation of a plurality of reels on which a plurality of types of symbols are respectively arranged based on an operation of a start switch, and for controlling the stop of each of the reels corresponding to the operated stop switch based on the lottery result of the winning type lottery means in response to an operation of a stop switch corresponding to the rotating reel; and a plurality of playing modes including a non-internal playing mode and a bonus internal playing mode (e.g., an RBB internal playing mode) to which a transition is made based on a winning of a bonus role in the non-internal playing mode. and a presentation state control means for transitioning the reel to one of a plurality of presentation states including a first presentation state (e.g., a non-AT presentation state) and a second presentation state (e.g., an AT presentation state) that is more advantageous to the player than the first presentation state. The reel control means equalizes the stop control of the plurality of reels when the selected winning type (e.g., a winning type "batting order chance role B1") is determined in the non-internal game state with the stop control of the plurality of reels when the selected winning type is determined in the bonus internal game state (see FIG. 6). When the selected winning type is determined in the first presentation state, an operation mode (e.g., left push, batting order 1 to 6) that allows the first role to win may be notified, and when an operation is performed in an operation mode that allows the first role to win , a special benefit (e.g., a lottery for an AT presentation state, setting the game as a ceiling consumption game, shortening the number of games until the ceiling is reached) that is advantageous to the player can be granted.

According to the present invention, it is possible to improve gameplay while maintaining the player's motivation to play.

The preferred embodiment of the present invention will be described in detail below with reference to the attached drawings. The dimensions, materials, and other specific values shown in the embodiment are merely examples to facilitate understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements that have substantially the same function and configuration are given the same reference numerals to avoid duplicated explanations, and elements that are not directly related to the present invention are not illustrated.

(Mechanical Configuration of Slot Machine 100)
1 and 2, a slot machine 100 as a gaming machine is provided with a housing 102 with an open front, and an upper front door 104 and a lower front door 106 which are rotatably arranged vertically side by side at one end of the front of the housing 102. A colorless and transparent symbol display window 108 made of a glass plate, a transparent resin plate or the like is provided at approximately the center of the lower part of the upper front door 104, and four reels 110 (left reel 110a, center reel 110b, right reel 110c, and fourth reel 110d) are provided at positions corresponding to the symbol display window 108 in the housing 102 so as to be independently rotatable. As shown in the pattern arrangement in Fig. 3(a) on the outer periphery of the left reel 110a, the center reel 110b, the right reel 110c, and the fourth reel 110d, a plurality of types of patterns are arranged in each of 20 equally divided regions, and the player can visually see a total of 12 patterns, each of which is located in the upper, middle, and lower rows of the left reel 110a, the center reel 110b, the right reel 110c, and the fourth reel 110d, through the pattern display window 108. Here, the four reels 110 are described as the left reel 110a, the center reel 110b, the right reel 110c, and the fourth reel 110d, respectively, but may be read as the first reel 110a, the second reel 110b, the third reel 110c, and the fourth reel 110d.

An operation unit installation stand 112 is formed on the top of the front lower door 106, and is provided with a medal insertion unit 114, a bet switch 116, a start switch 118, a stop switch 120, a performance switch 122, a settlement switch 123, and the like. The medal insertion unit 114 accepts medals inserted as game value through a medal insertion port 114a. The bet switch 116 inserts (bet) a specified number of medals required for one game from among the medals electrically stored inside the slot machine 100 (hereinafter simply referred to as credits).

The start switch 118 is composed of, for example, a lever capable of detecting tilting operation, and detects the start operation of the game by the player. The stop switches 120 (stop switch 120a, stop switch 120b, stop switch 120c, stop switch 120d) are provided corresponding to the left reel 110a, the center reel 110b, the right reel 110c, and the 4th reel 110d, respectively, and detect the stop operation by the player. In addition, when the stop switch 120 can be stopped, the first stop is when the player operates any of the stop switches 120a, 120b, 120c, and 120d to stop the game. After the first stop, the second stop is when the player operates any of the three stop switches 120 that have not been stopped. After the second stop, the third stop is when the player operates any of the two stop switches 120 that have not been stopped. After the third stop, the fourth stop is when the player operates the last remaining stop switch 120 to stop the game. The effect switch 122 is composed of, for example, a push switch and a jog dial switch arranged around it so that it can rotate freely, and detects push operations and rotation operations by which the player sets various settings related to the effect, such as the volume of the music. The settlement switch 123 is used to settle (pay out) the credited medals.

A liquid crystal display unit 124 that displays various images associated with the performance is provided approximately in the center of the top of the upper front door 104. Performance lamps 126, for example composed of high-brightness light-emitting diodes (LEDs), are provided at the top and left and right of the upper front door 104. Speakers 128 that perform auditory performances using sound effects, musical tones, etc. are provided at the left and right positions of the liquid crystal display unit 124 on the rear surface of the upper front door 104 and at the left and right positions on the rear surface of the lower front door 106.

The operation unit installation base 112 is provided with a main credit display unit 130 and a main payout display unit 132. In addition, a sub-credit display unit 134 and a sub-payout display unit 136 are provided between the symbol display window 108 and the operation unit installation base 112. The main credit display unit 130 and the sub-credit display unit 134 display the number of medals credited (number of credits), and the main payout display unit 132 and the sub-payout display unit 136 display the number of medals paid out.

Below the reels 110 in the housing 102, a medal payout device (medal hopper) 142 is provided for paying out medals from a medal discharge port 140a. In addition, at the lower front part of the lower front door 106, a tray section 140 is provided for storing medals paid out from the medal discharge port 140a. Also, a power switch 144 is provided inside the housing 102. The power switch 144 is operated by an administrator who manages the slot machine 100, and is used to switch between two states: a power-off state and a power-on state.

In addition, inside the cabinet 102, a setting key and a setting change switch (collectively referred to as a setting value setting means) (not shown) are provided on the main control board 200 described later. In the slot machine 100, when a predetermined key (operation key) is inserted into the setting key and turned from the OFF position to the ON position, and the power is turned on via the power switch 144, the slot machine 100 transitions to a setting change mode, and the setting value can be changed (also simply referred to as a setting change). The setting value indicates the degree of advantage (machine odds) of the player in stages, and is expressed in six stages, for example, from 1 to 6. In general, the setting value is set so that the higher the numerical value of the setting value, the higher the overall advantage in the game (the higher the expected number of coins to be won). Then, each time the setting change switch is pressed in a state in which the setting can be changed, the setting value is incremented by one, and the setting value is changed to one of the six setting values, for example, and when the start switch 118 is operated, the setting value is confirmed, and the setting key is returned to its original position (OFF position), ending the setting change mode and enabling play. Note that settings can only be changed for a certain period of time after the power switch 144 is operated to turn on the power.

In the slot machine 100, when a game can be started and a specified number of medals are bet, the active line A is activated and the operation of the start switch 118 is activated. Here, the bet includes the case where the credited medals are inserted through the operation of the bet switch 116, the case where medals are inserted through the medal insertion section 114, and the case where medals are automatically inserted based on the display of a replay role on the active line A, which will be described in detail later. The active line A is a line for determining whether a winning role has been won, and in this embodiment, there is one active line. As shown in FIG. 3(b), the active line A is set to a line connecting positions corresponding to the symbols stopped in the middle of the left reel 110a, the middle reel 110b, the middle reel 110c, and the middle reel 110d among the 12 symbols (4 reels × 3 rows, upper, middle, and lower) facing the symbol display window 108.

When the player operates the start switch 118, the game starts, the left reel 110a, the center reel 110b, the right reel 110c, and the fourth reel 110d are rotated, and a lottery for a winning type is executed. After that, the left reel 110a, the center reel 110b, the right reel 110c, and the fourth reel 110d are stopped according to the operation of the stop switches 120a, 120b, 120c, and 120d. Then, if a winning combination that can receive a medal payout is won based on the lottery result of the winning type lottery and the combination of the patterns displayed on the pay line A, the medal is paid out. If a winning combination that can receive a medal payout is not won or if a winning type that can receive a medal payout is won but not won, the game ends when the left reel 110a, the center reel 110b, the right reel 110c, and the fourth reel 110d are all stopped.

In this embodiment, the above-mentioned one game refers to a game from when a medal is inserted through the medal insertion section 114, when a credited medal is inserted through the operation of the bet switch 116, or when a medal is automatically inserted based on a replay role being displayed on the active line A, until the left reel 110a, middle reel 110b, right reel 110c, and fourth reel 110d are controlled to rotate and a winning type lottery is executed in response to the player's operation of the start switch 118, and the left reel 110a, middle reel 110b, right reel 110c, and fourth reel 110d corresponding to the operated stop switches 120a, 120b, 120c, and 120d are controlled to stop, respectively, in response to the result of the winning type lottery and the player's operation of the multiple stop switches 120a, 120b, 120c, and 120d, and when a winning role that may be awarded with a medal is won, the medal is paid out. In addition, if a player does not win a prize type that can receive a medal payout, or if a player wins but does not win, one game ends when the left reel 110a, center reel 110b, right reel 110c, and fourth reel 110d all come to a halt. However, the start of one game may be interpreted as the player operating the start switch 118 instead of the insertion of a medal or winning a replay role. The number of times one such game is repeated is defined as the number of games.

Figure 4 is a block diagram showing the schematic electrical configuration of the slot machine 100. As shown in Figure 4, the slot machine 100 is provided with a control board including a main control board 200 (main control unit) that controls the progress of the game, and a sub-control board 202 (sub-control unit) that controls the presentation according to the progress of the game. In addition, the transmission of electrical signals between the main control board 200 and the sub-control board 202 is limited to one direction only, from the main control board 200 to the sub-control board 202, from the viewpoint of preventing fraud, etc.

(Main control board 200)
The main control board 200 has semiconductor integrated circuits including a main CPU 200a which is a central processing unit, a main ROM 200b in which programs and the like are stored, and a main RAM 200c which functions as a work area, and generally controls the entire slot machine 100. Note that even if the power is cut off, the main RAM 200c retains data without erasing it, unless a setting change is made and the RAM is cleared.

The main control board 200 also has functional units such as an initialization means 300, a betting means 302, a winning type selection means 304, a reel control means 306, a determination means 308, a payout control means 310, a game state control means 312, a presentation state control means 314, and a command transmission means 316, which function when the main CPU 200a cooperates with the main RAM 200c based on a program stored in the main ROM 200b.

The main control board 200 receives various detection signals from the inserted medal detection unit 414b, which detects the insertion of medals into the medal insertion slot 114a, the bet switch 116, the start switch 118, and the stop switches 120a, 120b, 120c, and 120d, and the main CPU 200a executes various processes based on the received detection signals.

The initialization means 300 executes initialization processing on the main control board 200. The betting means 302 bets medals to be used in the game. The winning type selection means 304 performs a winning type selection based on the operation of the start switch 118, as will be described in detail later, to determine whether or not a winning role has been won, and more specifically, whether or not a winning type that includes a winning role has been won.

The reel control means 306 controls the rotation of the left reel 110a, middle reel 110b, right reel 110c, and fourth reel 110d in response to the operation of the start switch 118, and controls the stopping of the corresponding left reel 110a, middle reel 110b, right reel 110c, and fourth reel 110d in response to the operation of the stop switches 120a, 120b, 120c, and 120d corresponding to the rotating left reel 110a, middle reel 110b, right reel 110c, and fourth reel 110d, respectively. In addition, the reel control means 306 may extend the time from enabling the operation of the stop switches 120a, 120b, 120c, and 120d in the previous game to enabling the operation of the stop switches 120a, 120b, 120c, and 120d by the player to display the lottery result of the winning type lottery (which is disabled by completing the operation of the stop switches 120a, 120b, 120c, and 120d in the previous game) to a specified time, and during that time, perform a reel effect (freeze effect) in which the reels 110a, 110b, 110c, and the 4th reel 110d are rotated in various ways. The reel effect can be realized by not enabling any switch that should be enabled for a specified time, suspending a process that should be executed for a specified time, or not transmitting or receiving a signal of any switch that should be transmitted or received for a specified time.

The reel drive control unit 150 is also connected to the main control board 200. This reel drive control unit 150 drives the stepping motor 152 based on rotation start signals for the left reel 110a, center reel 110b, right reel 110c, and fourth reel 110d sent from the reel control means 306 in response to an operation signal from the start switch 118. The reel drive control unit 150 also stops driving the stepping motor 152 based on stop signals for the left reel 110a, center reel 110b, right reel 110c, and fourth reel 110d and detection signals from the rotation position detection circuit 154 sent from the reel control means 306 in response to an operation signal from the stop switch 120.

The determination means 308 determines whether or not a symbol combination corresponding to a winning role has been displayed on the pay line A. Here, the display of a symbol combination corresponding to a winning role on the pay line A may simply be referred to as winning. The payout control means 310 pays out medals in the number (value amount) corresponding to the winning role based on the fact that a symbol combination corresponding to a winning role has been displayed on the pay line A (winning). In addition, a medal payout device 142 is connected to the main control board 200, and the payout control means 310 dispenses medals while counting the number of medals paid out.

The game state control means 312 refers to the result of the winning type lottery and the judgment result of the judgment means 308, and transitions the game state to one of multiple game states. The presentation state control means 314 refers to the result of the winning type lottery, the judgment result of the judgment means 308, and transition information of the game state, and transitions the presentation state to one of multiple presentation states.

The command transmission means 316 sequentially determines game-related commands associated with the operation of the betting means 302, the winning type selection means 304, the reel control means 306, the determination means 308, the payout control means 310, the game state control means 312, the presentation state control means 314, etc., and sequentially transmits the determined commands to the sub-control board 202.

The main control board 200 is also provided with a random number generator 200d. The random number generator 200d sequentially increments the count value, loops it within a predetermined numerical range, and extracts the count value at a predetermined point in time to obtain a random number. The random number generated by the random number generator 200d of the main control board 200 (hereinafter referred to as the winning type lottery random number) is used to determine the gaming benefit to be awarded to the player, for example, the winning type by the winning type lottery means 304.

(Sub-control board 202)
Similarly to the main control board 200, the sub-control board 202 has various semiconductor integrated circuits including a sub-CPU 202a which is a central processing unit, a sub-ROM 202b which stores programs and the like, and a sub-RAM 202c which functions as a work area, and controls the performances, in particular, based on commands from the main control board 200. Similarly to the main RAM 200c, the sub-RAM 202c is also connected to a backup power supply (not shown), so that data is not erased and is retained even if the power supply is cut off. Similarly to the main control board 200, the sub-control board 202 is also provided with a random number generator 202d, and the random numbers generated by the random number generator 202d (hereinafter referred to as performance selection random numbers) are mainly used to determine the mode of the performance.

In addition, the sub-control board 202 has functional units such as an initialization determination means 330, a command receiving means 332, and a performance control means 334, which function in cooperation with the sub-RAM 202c based on the program stored in the sub-ROM 202b.

The initialization determination means 330 executes the initialization process in the sub-control board 202. The command receiving means 332 receives commands from other control boards such as the main control board 200, and processes the commands. The performance control means 334 receives a detection signal from the performance switch 122, and determines the performance of the game to be performed by each device of the liquid crystal display unit 124, the speaker 128, and the performance lamp 126 based on the received command. Specifically, the performance control means 334 determines image data to be displayed on the liquid crystal display unit 124, lighting data for the performance through lighting devices such as the performance lamp 126, the sub-credit display unit 134, and the sub-payout display unit 136, and determines audio data constituting the sound to be output from the speaker 128. Then, the performance control means 334 executes the performance of the determined game. In addition, the performance also includes auxiliary performance. The auxiliary effect is an effect that notifies the player of the correct operation mode of the stop switches 120a, 120b, 120c, and 120d, which is the winning condition for the correct role, when a selected winning type in which a correct role and an incorrect role overlap is won in the winning type lottery. This auxiliary effect allows the player to easily display the symbol combination corresponding to the correct role on the pay line A. The performance state in which this auxiliary effect is executed is called an AT (assist time) performance state. In addition, a so-called ART game state in which the AT performance state and an RT (replay time) game state, in which the probability of winning a replay role is high, are carried out in parallel, may also be used.

In the following, notification means managed by boards other than the main control board 200, including the sub-control board 202, such as the LCD display unit 124, performance lamps 126, speaker 128, sub-credit display unit 134, and sub-payout display unit 136, may be referred to as other notification means. In contrast, notification means managed by the main control board 200, such as the main credit display unit 130 and main payout display unit 132, may be referred to as main notification means (instruction monitor). In addition, the main notification means and other notification means capable of executing auxiliary performances may be collectively referred to as auxiliary performance execution means. The performance state control means 314 causes the auxiliary performance execution means to execute the auxiliary performance in the AT performance state.

(Table used in main control board 200)
FIG. 5 is an explanatory diagram for explaining winning combinations, FIG. 6 is an explanatory diagram for explaining a winning type selection table, and FIG. 7 is a diagram showing the numbers of symbols placed on the winning type selection table.

In the slot machine 100, as described in detail below, multiple types of game states and presentation states are provided, and the game states and presentation states are changed according to the progress of the game. In the main control board 200, multiple winning type lottery tables corresponding to the game states managed and controlled by the game state control means 312 are stored in the main ROM 200b. The winning type lottery means 304 extracts the corresponding winning type lottery table from the main ROM 200b according to the current setting value (which indicates the easiness of obtaining a game profit in stages) stored in the main RAM 200c and the current game state, and determines which winning type in the winning type lottery table corresponds to the winning type lottery random number obtained according to the operation signal of the start switch 118 based on the extracted winning type lottery table.

Here, the winning roles that make up the winning types extracted in the winning type lottery table include a replay role, a small role, and a bonus role. A replay role is a role that allows the player to play again without making a new medal bet when a symbol combination corresponding to the replay role is displayed on the active line A. A small role is a role that allows the player to receive a predetermined number of medals according to the symbol combination when a symbol combination corresponding to the small role is displayed on the active line A. A bonus role is a role that allows the game state managed by the game state control means 312 to transition to a bonus game state (a game state during RBB operation described later) when a symbol combination corresponding to the bonus role is displayed on the active line A.

As shown in FIG. 5, the winning role in this embodiment is a bonus role with a winning role "RBB". In addition, the winning roles "small role 1" to "small role 37" are provided as small roles. In addition, the winning roles "replay 1" to "replay 8" are provided as replay roles. In FIG. 5, one or more symbols constituting each winning role are associated with the left reel 110a, the center reel 110b, the right reel 110c, and the fourth reel 110d. In the following, the winning roles "small role 1" to "small role 13" may be abbreviated to the winning role "15-coin role", and the winning roles "small role 14" to "small role 35" may be abbreviated to the winning role "1-coin role".

Here, in this embodiment, when the stop switch 120 is operated by the player, if the symbols constituting the symbol combination corresponding to a possible winning combination are on the active line A, the reel control means 306 performs stop control so that the symbols stop on the active line A. Also, when the stop switch 120 is operated, if the symbols constituting the symbol combination corresponding to a possible winning combination are not on the active line A but are within a range equivalent to four symbol frames in the direction opposite to the rotation direction of the reel 110 (pulling-in range), the reel control means 306 performs stop control so that the number of separated symbols becomes the number of slipping frames, and the symbols constituting the symbol combination corresponding to the winning combination are pulled onto the active line A and then stopped after maintaining rotation for the number of slipping frames. In addition, when there are multiple symbols corresponding to winning combinations that can win prizes on the reel 110 and all of them are within the reel-in range of the reel 110, it is determined which symbol to reel in to the pay line A according to a predetermined priority order, and the stop control is performed so that the prioritized symbol is stopped after maintaining rotation for the number of sliding frames so as to reel in the winning line A. In addition, when the stop switch 120 is pressed, if a symbol constituting a symbol combination corresponding to a winning combination other than a winning combination that can win a prize is on the winning line A, the reel control means 306 also executes a so-called kicking process in parallel to prevent the symbol from stopping on the winning line A. In addition, as described later, when an operation mode (operation order or operation timing) is set as a winning condition for a winning combination included in a winning type, the reel control means 306 controls the stop so that the symbol combination corresponding to the winning combination can be displayed on the winning line A according to the operation mode of the player.

For example, the symbols constituting the symbol combinations corresponding to the winning roles "Replay 1" and "Minor role 1" are arranged on each reel 110 so that they can always be displayed on the pay line A by the above-mentioned stopping control. Such a winning role may be expressed as PB=1. On the other hand, for example, the symbols constituting the symbol combinations corresponding to the winning roles "Replay 3", "Minor role 16", and "RBB" are not always arranged on each reel 110 so that they can always be displayed on the pay line A by the above-mentioned stopping control, so so-called misses may occur. Such a winning role may be expressed as PB≠1.

As shown in FIG. 6, the winning type lottery table is divided into multiple winning areas, and the winning types to be selected vary depending on the game state, and the presence or absence of non-wins (misses) varies. FIG. 6 shows the winning areas (winning types) assigned to each game state (non-internal game state (non-internal), RBB internal game state (RBB internal), RBB operating game state (RBB operating)) and an overview of the winning combination (e.g., payout number) that can be displayed depending on the player's operation mode when the winning type is won. Note that hatched areas in the winning type lottery table indicate that the winning type cannot be won in that game state. Such winning type lottery tables are stored in the main ROM 200b in correspondence with each of the multiple game states. In addition, winning types surrounded by thin-lined boxes indicate winning types that allow for a lottery to be held to move to an advantageous zone, and winning types surrounded by thick lines indicate winning types that do not allow for a lottery to be held to move to an advantageous zone, and therefore do not allow for a lottery to be held to move to an advantageous zone.

In the winning type lottery table, each partitioned winning area is associated with a predetermined number of entries (winning range value), which is a numerical value indicating the winning range, and a winning type. The total number of entries in all winning areas assigned to each game state is the total number of winning type lottery random numbers (65536). Therefore, the probability of each winning type being determined is the value obtained by dividing the number of entries associated with the winning area by the total number of winning type lottery random numbers. The winning type lottery means 304 sequentially obtains the number of entries from the multiple winning areas in the winning type lottery table starting with the highest number based on the game state at that time, subtracts the number of entries from the winning type lottery random number, and if the value after subtraction is less than 0, the winning type associated with the winning area at that time is the lottery result of the winning type lottery. Also, if the number of entries in all winning areas 1 or more are subtracted from the winning type lottery random number and the value after subtraction is 0 or more, the winning type "miss" of winning area 0 is the lottery result of the winning type lottery.

Here, we will add some details about the winning role "RBB" that constitutes the winning type "RBB". The specified first-class special role RB is a role that increases the number of combinations of symbols related to winning for each specified number, or increases the probability of the condition device related to winning for each specified number activating, and is capable of activating in a predetermined case and continuing to operate until the result of the game is obtained not more than 12 times. Here, the condition device is a device whose operation is a necessary condition for the display of a combination of symbols related to winning, replay, the role, or the operation of the role continuous operation device, and is activated when the winning type lottery (a lottery by a computer performed in the gaming machine) is won, that is, it means a winning flag. And the role continuous operation device related to the first-class special role that constitutes the winning type "RBB" (winning role "RBB") is a device that can continuously operate the first-class special role RB, and is activated when a specific combination of symbols is displayed and ends its operation when it is predetermined.

According to the winning type lottery table in FIG. 6, for example, winning area 0 is associated with the winning type "miss." If such a winning type is won, the symbol combination corresponding to any of the winning roles shown in FIG. 5 will not be displayed on the pay line A, and no medals will be paid out.

In addition, winning area 1 is associated with the winning type "small win ALL" which includes (wins) the winning roles "small win 1" to "small win 37" in duplicate, and winning area 2 is associated with the winning type "1 coin ALL" which includes (wins) the winning roles "small win 14" to "small win 33" in duplicate.

In addition, winning area 3 is associated with the winning type "Weak Cherry 1," which includes both the winning role "Small Role 22," which pays out one coin, and the winning role "Small Role 37," which pays out three coins.

Furthermore, winning regions 4 to 27 are each associated with a selected winning type (winning type "Strawberry 1" to "Strawberry 24") that includes both a correct combination with a payout of 15 coins (winning combination "Small combination 2" to "Small combination 13") and an incorrect combination with a payout of 1 coin (winning combination "Small combination 14" to "Small combination 29"). Note that hereinafter, the 24 winning types in winning regions 4 to 27 may be abbreviated to simply be the winning type "Strawberry".

In addition, the winning types "batting order chance role A1" to "batting order chance role A4" that include at least the winning role "small role 1" with a payout of 15 coins, the winning role "small role 35" with a payout of 1 coin, and the winning role "small role 36" with a payout of 2 coins are associated with the winning areas 28 to 31, respectively. In addition, the winning types "batting order chance role B1" to "batting order chance role B4" that include at least the winning role "small role 1" with a payout of 15 coins, and the winning roles "small role 33" and "small role 34" with a payout of 1 coin are associated with the winning areas 32 to 35, respectively. In the following, the four winning types in the winning areas 28 to 31 may be simply abbreviated as the winning type "batting order chance role A", and the four winning types in the winning areas 32 to 35 may be simply abbreviated as the winning type "batting order chance role B". Additionally, the winning type "Batting Order Chance Role A" and the winning type "Batting Order Chance Role B" may be abbreviated to simply the winning type "Batting Order Chance Role."

Furthermore, winning regions 36 to 41 are associated with winning types "Normal Replay 1" to "Normal Replay 6," which include overlapping winning roles of "Replay 1" to "Replay 3" and "Replay 5" to "Replay 8."

The winning area 42 is associated with a winning type "Chance Replay" that includes the winning roles "Replay 1" and "Replay 3" in overlapping fashion. The winning area 43 is associated with a winning type "Weak Bell" that includes the winning roles "Replay 1" to "Replay 4" in overlapping fashion. The winning area 44 is associated with a winning type "Strong Bell" that includes the winning roles "Replay 1" to "Replay 5" in overlapping fashion. The winning area 45 is associated with a winning type "Strong Cherry 1" that includes the winning roles "Replay 1" and "Replay 4" in overlapping fashion. The winning area 46 is associated with a winning type "Strong Cherry 2" that includes the winning roles "Replay 1", "Replay 4", and "Replay 5" in overlapping fashion. The winning types "Normal Replay 1" to "Normal Replay 6", "Chance Replay", "Weak Bell", "Strong Bell", "Strong Cherry 1", and "Strong Cherry 2" may be abbreviated simply as the winning type "Replay".

In addition, the winning area 47 is associated with the winning type "Weak Cherry 2" which includes the winning combination "RBB" and the winning combinations "Small combination 18", "Small combination 29", and "Small combination 30". The winning area 48 is associated with the winning type "Common 1" which includes the winning combinations "RBB" and "Small combination 14", "Small combination 18", "Small combination 26", "Small combination 29", and "Small combination 30". The winning area 49 is associated with the winning type "Common 1" which includes the winning combinations "RBB" and "Small combination 17", "Small combination 31" to "Small combination 33". The winning area 50 is associated with the winning type "RBB" which includes the winning combination "RBB" alone. Note that if the winning areas 47 to 49 are won in the RBB internal game state, only the small combination will be won.

When a winning type that includes multiple overlapping winning combinations is won, the winning conditions for which symbol combination corresponding to the winning combination is preferentially displayed on the pay line A are set, for example, the order in which the stop switches 120a, 120b, 120c, and 120d are operated.

In the following description, the operation of the stop switches 120a, 120b, 120c, 120d that stop the reels in the order of left reel 110a, center reel 110b, right reel 110c, and fourth reel 110d is referred to as "batting order 1", the operation of the stop switches 120a, 120b, 120c, 120d that stop the reels in the order of left reel 110a, center reel 110b, fourth reel 110d, and right reel 110c is referred to as "batting order 2", and the operation of the stop switches 120a, 120b, 120c, 120d that stop the reels in the order of left reel 110a, right reel 110c, center reel 110b, and fourth reel 110d is referred to as "batting order 3".

The operation of the stop switches 120a, 120b, 120c, 120d that stop the reels in the order of the 4th reel 110d, the left reel 110a, the center reel 110b, and the right reel 110c is defined as "batting order 19", the operation of the stop switches 120a, 120b, 120c, 120d that stop the reels in the order of the 4th reel 110d, the left reel 110a, the right reel 110c, and the center reel 110b is defined as "batting order 20", and the operation of the stop switches 120a, 120b, 120c, 120d that stop the reels in the order of the 4th reel 110d, the center reel 110b, the left reel 110a, and the right reel 110c is defined as "batting order 21", The operation of the stop switches 120a, 120b, 120c, 120d that stop the reels in the order of 4th reel 110d, center reel 110b, right reel 110c, and left reel 110a is called "batting order 22", the operation of the stop switches 120a, 120b, 120c, 120d that stop the reels in the order of 4th reel 110d, right reel 110c, left reel 110a, and center reel 110b is called "batting order 23", and the operation of the stop switches 120a, 120b, 120c, 120d that stop the reels in the order of 4th reel 110d, right reel 110c, center reel 110b, and left reel 110a is called "batting order 24".

In addition, in the following description, the operation of the stop switches 120a, 120b, 120c, 120d that stop the left reel 110a first is referred to as a "left push", the operation of the stop switches 120a, 120b, 120c, 120d that stop the center reel 110b first is referred to as a "center push", the operation of the stop switches 120a, 120b, 120c, 120d that stop the right reel 110c first is referred to as a "right push", and the operation of the stop switches 120a, 120b, 120c, 120d that stop the 4th reel 110d first is referred to as a "4th push".

For example, in the game state inside the RBB described below, if the winning type "Strawberry 1" in winning area 4 is won and an operation is performed according to the correct operation mode (batting order 1), the stop control is performed so that the symbol combination corresponding to the winning role "Small role 2", which is a correct role with a payout of 15 coins, is preferentially displayed on the effective line A. Also, if an operation is performed according to batting orders 2 to 6 or 13 to 24, the stop control is performed so that the symbol combination corresponding to the winning role "1 coin role", which is an incorrect role with a payout of 1 coin, is preferentially displayed on the effective line A, and if an operation is performed according to batting orders 7 to 12, the stop control is performed so that the symbol combination corresponding to the winning role "1 coin role", which is an incorrect role with a payout of 1 coin, is preferentially displayed on the effective line A with a probability of 1/2.

The number of winning symbols for the winning type "Strawberry Batting Order" in winning areas 4 to 27 is set to 1870, and the winning probability is set to be equal. Since a player usually cannot know which winning type he/she has won, the above-mentioned winning areas 4 to 27 are provided to make it difficult for a correct combination to win. Also, as described above, even if the stop switches 120a, 120b, 120c, and 120d are operated in an operation mode in which an incorrect combination is preferentially displayed, the symbol combination corresponding to the incorrect combination is not necessarily displayed on the pay line A, so that a miss may occur depending on the operation mode (PB ≠ 1). Similarly, the number of winning symbols for the winning type "Chance Batting Order A" in winning areas 28 to 31 is set to 128, and the winning probability is set to be equal. Also, the number of winning symbols for the winning type "Chance Batting Order B" in winning areas 32 to 35 is set to 612, and the winning probability is set to be equal. Since players usually cannot know which winning type they have won, by providing winning areas 28 to 35 as described above, it is made difficult for players to win the correct combination that maximizes the gaming profit in each presentation state.

When any of the above winning types is won, the internal winning flag corresponding to the winning type is established (ON), and the stop control of each reel 110 is performed according to the establishment status of this internal winning flag. At this time, if a winning type including a small role is won, but the symbol combination corresponding to the winning role cannot be displayed on the active line A during the game, the internal winning flag is turned OFF after the game ends. In other words, the right to win a small role is limited only to the game in which the winning type including a small role is won, and the right cannot be carried over to the next game. On the other hand, when a winning type including the winning role "RBB" is won, the RBB internal winning flag is established (ON), and the RBB internal winning flag is carried over across games until the symbol combination corresponding to the winning role "RBB" is displayed on the active line A. In addition, when an internal win flag corresponding to a win type that includes a replay role is established, a symbol combination corresponding to one of the replay roles included in that win type is always displayed on the active line A, and after the processing required to play the next game without requiring a medal is performed, the internal win flag is turned OFF.

(Game state transition)
Here, the transition of the game state will be explained with reference to Fig. 8. Here, a plurality of game states are prepared, such as a non-internal game state, an internal RBB game state, and an RBB operation game state. As described later, each game state is transitioned according to the winning of a bonus role, winning (operation), and ending.

The non-internal game state is a game state that corresponds to the initial state among multiple game states. In such a non-internal game state, the probability of winning a replay role is set to approximately 1/7.3. In addition, in the non-internal game state, the winning role "RBB" is determined with a predetermined probability (for example, approximately 1/10).

The game state control means 312 transitions the game state in response to the winning combination "RBB". For example, in a game in which the winning combination "RBB" is won, when a symbol combination corresponding to the winning combination "RBB" is displayed on the active line A, the game state control means 312 transitions the game state to a game state in which RBB is active (1).

In the RBB-activated game state, the probability of winning a replay role is set to 0. In this RBB-activated game state, the possible winning types are set as "small role ALL" in winning area 1 and "1 piece ALL" in winning area 2. When the "small role ALL" winning type is won, a symbol combination corresponding to any of the winning roles "small role 1" to "small role 37" is displayed on the active line A, and when the "1 piece ALL" winning type is won, the game is stopped and controlled so that a symbol combination corresponding to any of the winning roles "small role 14" to "small role 33" is displayed on the active line A. Here, the expected number of coins per unit of play in the RBB-activated game state is lowered by the configuration of the small roles.

When the conditions for terminating the game state during RBB operation are met, i.e., when the number of coins won reaches a predetermined number, the game state control means 312 transitions the game state to a non-internal game state (2).

On the other hand, in a game in which the winning combination "RBB" is won, if the symbol combination corresponding to the winning combination "RBB" cannot be displayed on the active line A, the game state control means 312 transitions the game state to an RBB internal game state (3).

In the RBB internal game state, the probability of winning a replay role is set to approximately 1/5.9. Also, in the RBB internal game state, the winning type "miss" cannot be won. In other words, if the symbol combination corresponding to the winning role "RBB" cannot be displayed on the active line A in the winning game of the winning role "RBB", the symbol combination corresponding to the winning role "RBB" cannot be displayed on the active line A after that, since the minor role and the replay role are controlled to stop on the active line A in priority to the winning role "RBB". Therefore, once the game state transitions to the RBB internal game state, the RBB internal game state is maintained without any transition of the game state. Here, while maintaining such an RBB internal game state, the AT performance state is realized in the RBB internal game state.

Here, in the RBB internal game state, multiple types of correct roles are won without overlapping with each other, so the chances of winning a correct role can be increased, and as a result, for example, by performing an auxiliary performance in the AT performance state in the RBB internal game state, medals can be easily won. On the other hand, in the RBB operation game state, multiple types of correct roles are won in overlapping fashion, so there are fewer chances of winning a correct role, and therefore there are fewer chances of winning a correct role than in the AT performance state in other game states, making it difficult for the player to increase the medals he owns. Therefore, it is possible to realize a specification (accelerator RBB) in which the RBB operation game state is inferior to the RBB internal game state in terms of medal winning performance, while having the function of the RBB operation game state in which the winning probability of a winning role related to winning is higher than in the RBB internal game state.

Comparing the non-internal game state and the RBB-operated game state in FIG. 8, the medal acquisition performance must be at least higher in the RBB-operated game state than in the non-internal game state. In this embodiment, the medal acquisition performance in the RBB-operated game state is kept low, thereby increasing the medal acquisition performance in the RBB-internal game state while keeping the overall medal acquisition performance low. However, if the medal acquisition performance in the RBB-operated game state is kept low, it is necessary to accordingly lower the medal acquisition performance in the non-internal game state. Therefore, in this embodiment, in order to lower the medal acquisition performance in the non-internal game state, the stop control is switched between the non-internal game state and the RBB-internal game state, as shown in the winning type lottery table in FIG. 6.

Specifically, when the winning type "Strawberry" is won, in the RBB internal game state, the reel control means 306 performs stop control so that the winning roles "Small Role 2" to "Small Role 13", each with a payout number of 15 coins, are displayed on the active line A in accordance with a predetermined operation mode by the player, but in the non-internal game state, the winning roles "Small Role 2" to "Small Role 13" are not allowed to win, and a winning role with a payout number of 1 coin is displayed on the active line A. Note that, here, a configuration has been described in which the winning roles "Small Role 2" to "Small Role 13" are not allowed to win in the non-internal game state, but it is also possible to configure the winning roles "Small Role 2" to "Small Role 13" to win, but with a lower probability of winning than in the RBB internal game state. Also, in the non-internal game state, the configuration has been described in which the winning roles "Small Role 2" through "Small Role 13" are not awarded even if the winning type "Ichigo Batting Order", that is, any of the winning types "Ichigo Batting Order 1" through "Ichigo Batting Order 24", are won. However, the configuration may be such that the winning roles "Small Role 2" through "Small Role 13" are not awarded in at least one of the winning types "Ichigo Batting Order", and the winning roles "Small Role 2" through "Small Role 13" are awarded in the other winning types "Ichigo Batting Order".

In addition, the reel control means 306 may change the stop control when the above-mentioned winning type "Strawberry" is won, and may also change the stop control when the winning type "Chance role for batting order" is won. For example, when the winning type "Chance role for batting order" is won, in the RBB internal game state, the reel control means 306 performs stop control so that the winning role "Small role 1" with a payout of 15 coins is displayed on the effective line A according to a predetermined operation mode by the player, but in the non-internal game state, the winning role "Small role 1" is not allowed to win, or the winning probability is lowered compared to the RBB internal game state, and a winning role with a payout of less than 15 coins is displayed on the effective line A. Also, in the non-internal game state, the configuration has been described in which the winning role "small role 1" is not awarded or the winning probability is reduced even if the winning role is the winning type "batting order chance role", that is, the winning types "batting order chance role A1" to "batting order chance role A4" and the winning types "batting order chance role B1" to "batting order chance role B4". However, the winning role "small role 1" may not be awarded or the winning probability may be reduced in at least one of the winning types of the winning types "batting order chance role", and the winning role "small role 1" may be awarded with a high probability in other winning types of the winning types "batting order chance role".

This configuration provides the functionality of the RBB operating game state, which provides a higher probability of winning a prize-related winning combination than the RBB internal game state, while realizing a specification in which the RBB operating game state is inferior to the RBB internal game state in terms of medal acquisition performance, and makes it possible to improve medal acquisition performance in the RBB operating game state compared to the non-internal game state.

(Transition of performance state)
9 is an explanatory diagram for explaining the transition of the presentation state. The following describes in detail the presentation state transitioned by the presentation state control means 314 in the main control board 200. Note that the following describes the case where the game state is the RBB internal game state.

Here, in order to comprehensively and uniformly determine whether or not the game state with high medal acquisition performance is biased, a game zone having a performance related to the instruction function, that is, a game zone advantageous to the player, including a game zone in which an auxiliary performance (instruction function) is executed, is defined as an advantageous zone. Note that, when an auxiliary performance is activated as a result of a lottery or the like related to the activation of the auxiliary performance on the main control board 200, the advantageous zone is a game zone in which information indicating the content of the instruction may be transmitted to a peripheral board such as the sub-control board 202 only when the content of the instruction is displayed on the main notification means so that the main control board 200 can identify it. Also, unlike the advantageous zone, a game zone in which the auxiliary performance (instruction function) cannot be executed is defined as a non-advantageous zone. Therefore, multiple performance states belong to either the advantageous zone or the non-advantageous zone, which are game zones. In this embodiment, almost all performance states belong to the advantageous zone, and a non-advantageous zone is realized in some performance states (here, the first game of the non-advantageous waiting performance state).

In addition, in the advantageous zone, among the winning modes in which the correct combination would be missed without the auxiliary effect, in the selected winning type in which the payout for the correct combination is the maximum (here, 15 coins), when an auxiliary effect that assists in winning the correct combination (an auxiliary effect that can win the maximum number of payout coins) is performed, this must be notified, for example, by lighting up the zone indicator 160.

In addition, in non-advantageous zones, the probability of winning a type of win can be made different for each setting value, but the probability of deciding to transition to a presentation state with auxiliary effects (AT presentation state) for the same winning type must not be made different for each setting value. On the other hand, in advantageous zones, both the probability of winning a type of win and the probability of deciding to transition (or add) to a presentation state with auxiliary effects (AT presentation state) for the same winning type can be made different for each setting value.

Therefore, in addition to managing the transition of the presentation state, the presentation state control means 314 also manages the transition between the non-advantageous zone and the advantageous zone. Furthermore, regardless of this management, the advantageous zone is forcibly terminated when the following termination conditions are met. For example, the zone is forcibly terminated when the value counted in the advantageous zone reaches a predetermined value (for example, the number of games played during the zone reaches 1,500 games or the net increase in number of coins exceeds 2,400 coins). In either case, the presentation state control means 314 resets all information updated in the advantageous zone (all variables that affect the performance related to the instruction function) by transitioning from the advantageous zone to the non-advantageous zone.

(Non-AT performance state, AT performance state)
In the non-AT performance state, the frequency of auxiliary performance is much lower than in the AT performance state, and the number of medals that can be acquired is limited because auxiliary performance is hardly performed. Here, six performance states are provided as the non-AT performance state, including a normal performance state, a CZ performance state (a chance zone performance state), a special zone performance state, an advantageous waiting performance state, a non-advantageous waiting performance state, and a pull-back performance state.

In the AT performance state, by having the auxiliary performance execution means execute an auxiliary performance when the selected winning type is won, the player can win many medals while reducing medal consumption. Therefore, by transitioning to the AT performance state, the player can play at an advantage compared to a non-AT performance state. Here, there are four AT performance states: OP performance state (opening performance state), normal AT performance state, continuation performance state, and special specialized zone performance state. Each performance state will be explained individually below.

(Each performance state)
The normal presentation state is a presentation state that corresponds to the initial state among multiple presentation states. The presentation state control means 314 performs a CZ lottery in the normal presentation state. The CZ lottery is a lottery that determines the transition to the CZ presentation state, and the presentation state control means 314 performs a CZ lottery with different probabilities for each winning type determined by the winning type lottery, as will be described in detail later. Then, when the CZ lottery is won in the normal presentation state, the presentation state control means 314 transitions the presentation state to the CZ presentation state (1).

In the CZ presentation state, the presentation state control means 314 performs an AT lottery. The AT lottery is a lottery that determines whether to transition to the AT presentation state (normal AT presentation state), and the presentation state control means 314 performs the AT lottery with different probabilities for each winning type determined by the winning type lottery. Then, if the AT lottery is won in the CZ presentation state, the presentation state control means 314 transitions the presentation state to the OP presentation state, which is the AT presentation state (2). Note that the CZ presentation state can be said to be a more advantageous presentation state than the normal presentation state, since it may be determined to transition to the normal AT presentation state, in which auxiliary presentations are executed.

On the other hand, when a predetermined end condition is met in the CZ presentation state (for example, a predetermined number of plays has elapsed without winning the AT lottery), the presentation state control means 314 transitions the presentation state to the normal presentation state (3).

In addition, when a predetermined ceiling condition (for example, the ceiling number of plays passes consecutively without transitioning from the normal presentation state, CZ presentation state, or pull-back presentation state to any other presentation state) is met in the normal presentation state or CZ presentation state without transitioning to the OP presentation state or special specialized zone presentation state (so-called reaching the ceiling), the presentation state control means 314 transitions the presentation state to the OP presentation state (2), (4).

In the OP presentation state, the auxiliary presentation is executed until a predetermined end condition (for example, five wins in the correct winning type and five auxiliary presentations are executed) is met. Then, when the predetermined end condition is met in the OP presentation state, the presentation state control means 314 transitions the presentation state to the specialized zone presentation state (5). In the specialized zone presentation state, the difference in the number of coins (net increase in the number of coins) that can be acquired in the normal AT presentation state to which the state is subsequently transitioned is determined by lottery. The difference in the number of coins is represented by the difference between the number of coins paid out for the winning combination that has been won and the specified number spent on that play. The specialized zone presentation state continues for, for example, 15 plays, and when 15 plays have elapsed, the presentation state control means 314 transitions the presentation state to the normal AT presentation state (6).

In the normal AT performance state, the auxiliary performance is executed until a predetermined end condition (for example, winning the difference in the number of medals determined in the specialized zone) is met. In other words, the normal AT performance state is a difference-in-number-managed AT performance state. Then, when a predetermined end condition is met in the normal AT performance state, the performance state control means 314 transitions the performance state to the standby performance state indicated by the dashed dotted line (7), (8).

The standby presentation state is divided into an advantageous standby presentation state, which is an advantageous section, and a non-advantageous standby presentation state, which is a non-advantageous section. Although a detailed explanation will be given later, in the final game of the normal AT presentation state, the presentation state control means 314 performs a continuation lottery to determine whether or not to transition (continue) to the normal AT presentation state again. If the continuation lottery is won, the presentation state control means 314 continues the advantageous section and temporarily transitions the presentation state to the advantageous standby presentation state (7). In addition, even if the continuation lottery is not won, the presentation state control means 314 performs an advantageous continuation lottery when a specific condition is established, and if the advantageous continuation lottery is won, the presentation state control means 314 continues the advantageous section and transitions the presentation state to the advantageous standby presentation state (7). On the other hand, if the continuation lottery is not won and the specific condition is not established, or if the specific condition is established but the advantageous continuation lottery is not won, the presentation state control means 314 transitions the advantageous section to the non-advantageous section and transitions the presentation state to the non-advantageous standby presentation state (8).

The standby presentation state continues for two plays, whether it is an advantageous standby presentation state or an unadvantageous standby presentation state. If the continuation lottery is won and the state transitions to an advantageous standby presentation state, the presentation state control means 314 transitions the presentation state to a continuation presentation state after two plays have elapsed (9).

In addition, if the continuation lottery is not won, but the advantageous continuation lottery is won and the state transitions to the advantageous standby presentation state, the presentation state control means 314 conducts a continuation lottery for each of the two games. Then, after two games have elapsed, the presentation state control means 314 transitions the presentation state to the continuation presentation state, regardless of whether the continuation lottery is won or not (9).

On the other hand, when the non-advantageous waiting presentation state is entered, the presentation state control means 314 performs a favorable zone transition lottery during the first play to determine whether or not to transition to a favorable zone. Note that the favorable zone transition lottery in this embodiment is always won. Therefore, the presentation state control means 314 transitions the play zone to the favorable zone when the first play in the non-advantageous waiting presentation state ends. Also, when the non-advantageous waiting presentation state is entered, the presentation state control means 314 performs a continuation lottery for each of the two plays. Then, after two plays have elapsed, the presentation state control means 314 transitions the presentation state to the continuation presentation state, regardless of whether or not the continuation lottery is won (10).

The continuation presentation state continues until a predetermined end condition (for example, the passage of 10 games) is met, during which time the presentation control means 334 notifies the result of the continuation lottery. If the continuation lottery is won, the presentation state control means 314 transitions again to the specialized zone presentation state (11). On the other hand, if the continuation lottery is not won, the presentation state control means 314 transitions the presentation state to the pullback presentation state (12). Note that in the continuation presentation state, if the continuation lottery is not won, a so-called rewrite lottery may be held to determine by lottery whether to transition to the normal AT presentation state.

The pull-back presentation state continues until a predetermined end condition (e.g., 30 plays have elapsed), during which time the presentation state control means 314 conducts a pull-back lottery for the normal AT presentation state. If the pull-back lottery is won, the presentation state control means 314 transitions the presentation state to the specialized zone presentation state (13). On the other hand, if the pull-back lottery is not won and the end condition is met, the presentation state control means 314 transitions the presentation state to the normal presentation state (14).

In the normal presentation state, CZ presentation state, and pull-back presentation state shown by dashed lines, when a predetermined winning type (for example, winning types "Replay 3" and "Replay 4") is selected by the winning type lottery, the presentation state control means 314 determines by lottery whether or not to execute a locked 3 reel presentation (freeze presentation), which will be described in detail later. Then, when it is determined that a locked 3 reel presentation should be executed, the reel control means 306 executes the locked 3 reel presentation, and the presentation state control means 314 transitions the presentation state to a special specialized zone presentation state for the next game (15).

The special specialized zone presentation state is a state that is more advantageous to the player than the specialized zone presentation state. Specifically, in the special specialized zone presentation state, like the specialized zone presentation state, the difference in number of coins (net increase in number of coins) that can be obtained in the normal AT presentation state to which it is subsequently transitioned is determined by lottery, but the difference in number of coins that is determined is more likely to be a value larger than in the specialized zone presentation state. For example, in the special specialized zone presentation state, a total of 2,400 coins is determined, which is the maximum net increase in number of coins that can be obtained in one advantageous zone. Note that the special specialized zone presentation state may be transitioned to when a specific condition, which will be described in detail later, is met, in addition to when it is determined that the reel presentation of lock 3 is to be executed.

Then, when the special specialized zone presentation state ends, the presentation state control means 314 transitions the presentation state to the normal AT presentation state (16).

The specific processing on the main control board 200 and the sub-control board 202 is explained below based on the flowchart.

(CPU Initialization Processing of Main Control Board 200)

(Step S120-1)
The main CPU 200a acquires a signal from the input port 1, and judges whether the setting value switching condition is satisfied based on the acquired signal from the input port 1. As a result, if it is judged that the setting value switching condition is not satisfied, the setting value switching process is terminated, and if it is judged that the setting value switching condition is satisfied, the process proceeds to step S120-3. Here, the signal from the input port 1 includes a signal indicating whether the front upper door 104 and the front lower door 106 are open or not, and a signal indicating whether the setting key is turned on or not.

(Timer interrupt processing of main control board 200)
32 is a flow chart for explaining the timer interrupt process in the main control board 200. The main control board 200 is provided with a reset clock pulse generating circuit that generates a clock pulse every predetermined period (1.49 milliseconds in the simultaneous rotation reference example, hereinafter referred to as "1.49 ms").

(Selection type)
As described above, in the slot machine 100 of this embodiment, the winning type "Strawberry in Batting Order" is adopted as the selectable winning type, and by performing auxiliary effects in the AT performance state, the expected number of winning coins per unit of play in the AT performance state can be relatively increased compared to the normal performance state.

Figure 33 is an explanatory diagram for explaining the winning mode of the winning type "Strawberry Batting Order". Here, the stop control will be explained using the winning type "Strawberry Batting Order 1" with batting orders 1, 2, and 7 as the winning type "Strawberry Batting Order". As shown in the upper part of Figure 33, the winning type "Strawberry Batting Order 1" is a selected winning type that includes a winning combination of "Small Winning Role 2" (correct combination) with a payout of 15 coins, and "Small Winning Role 14", "Small Winning Role 15", "Small Winning Role 18", and "Small Winning Role 19" (incorrect combination) with a payout of 1 coin.

In this case, when setting the priority based on the types of pattern combinations that can be displayed on the active line A, the more types of pattern combinations of winning roles that can be displayed on the active line A, the higher the priority is set. Also, when setting the priority based on the number of medals paid out, the more the number of medals paid out for minor roles corresponding to the pattern combinations displayed on the active line A, the higher the priority is set.

As shown in FIG. 33, when the winning type "Strawberry 1" is won and the stop switch 120a is operated to stop the left reel 110a first according to the correct operation mode of batting order 1, the pattern "Replay", which constitutes the winning role "Minor Role 2" that will pay out the most medals at 15, is set to be displayed preferentially among the patterns to be drawn, "Replay", "Strawberry A", and "Black Circle". Then, the reel control means 306 controls the stop so that the pattern "Replay" is displayed preferentially on the pay line A in response to the operation of the stop switch 120a. Note that the pattern "Replay" is always displayed on the pay line A by the stop control because PB=1 on the left reel 110a. In this way, by stopping the symbol "Replay" on the pay line A of the left reel 110a, the possibility of winning the winning role "small role 19" included in the winning type "batting order strawberry 1" is eliminated, and only the winning roles "small role 2", "small role 14", "small role 15", and "small role 18" have the possibility of winning. Next, when the stop switch 120b is operated to stop the middle reel 110b second according to the batting order 1, which is the correct operation mode, the symbol "Strawberry A" constituting the winning role "small role 2" which has the largest number of medals paid out, 15, among the symbols "Strawberry A" and "Cherry" to be drawn in is set to be preferentially displayed. Then, the reel control means 306 performs stop control so that the symbol "Strawberry A" is preferentially displayed on the pay line A in response to the operation of the stop switch 120b. Note that the symbol "Strawberry A" is always displayed on the pay line A by the stop control because PB=1 on the middle reel 110b. In this way, by stopping the symbol "Strawberry A" on the pay line A of the center reel 110b, the winning combination "small combination 18" included in the winning type "batting order strawberry 1" has no possibility of winning, and only the winning combinations "small combination 2", "small combination 14", and "small combination 15" have the possibility of winning. Next, when the stop switch 120c is operated to stop the right reel 110c third according to the batting order 1, which is the correct operation mode, the symbol "bell" constituting the winning combination "small combination 2" which has the largest number of medals paid out, 15, among the symbols to be drawn, "bell", "red 7", and "cherry", is set to be preferentially displayed. Then, the reel control means 306 performs stop control so that the symbol "bell" is preferentially displayed on the pay line A in response to the operation of the stop switch 120c. Note that the symbol "bell" is always displayed on the pay line A by the stop control because PB=1 on the right reel 110c. In this way, by stopping the symbol "Bell" on the pay line A of the right reel 110c, the winning roles "Small Role 14" and "Small Role 15" included in the winning type "Strawberry 1" are no longer likely to win, and only the winning role "Small Role 2" has the possibility of winning. Next, when the stop switch 120d is operated to stop the 4th reel 110d fourth according to the batting order 1, which is the correct operation mode, the symbol "Replay" to be drawn in is set to be displayed preferentially. Then, the reel control means 306 performs stop control so that the symbol "Replay" is preferentially displayed on the pay line A in response to the operation of the stop switch 120d. Note that the symbol "Replay" can always be displayed on the pay line A by the stop control, since PB=1 on the 4th reel 110d. In this way, the symbol "Replay" stops on the pay line A of the 4th reel 110d, and the winning role "Small Role 2" is confirmed to win. Here, by performing the operation in batting order 1, which is the correct operation mode, it is possible to win the winning role "minor role 2" (correct role) with PB = 1, which can receive the maximum number of payout coins, 15 coins.

Next, as shown in FIG. 33, when the winning type "Strawberry 1" is won and the stop switch 120a is operated to stop the left reel 110a first according to the incorrect operation mode of "Strawberry 2", the pattern "Replay" constituting the winning role "Minor Role 2" which will pay out the most medals at 15 coins is set to be preferentially displayed among the patterns "Replay", "Strawberry A", and "Black Circle" to be drawn in. Then, the reel control means 306 performs stop control so that the pattern "Replay" is preferentially displayed on the pay line A in response to the operation of the stop switch 120a. Note that the pattern "Replay" is always displayed on the pay line A by the stop control because PB=1 on the left reel 110a. In this way, by stopping the symbol "Replay" on the pay line A of the left reel 110a, the possibility of winning the winning role "small role 19" included in the winning type "batting order strawberry 1" is eliminated, and only the winning roles "small role 2", "small role 14", "small role 15", and "small role 18" have the possibility of winning. Next, when the stop switch 120b is operated to stop the center reel 110b second according to the batting order 2, which is an incorrect operation mode, the symbol "Strawberry A" constituting the winning role "small role 2" which has the largest number of medals paid out, 15, among the symbols "Strawberry A" and "Cherry" to be drawn in is set to be preferentially displayed. Then, the reel control means 306 performs stop control so that the symbol "Strawberry A" is preferentially displayed on the pay line A in response to the operation of the stop switch 120b. Note that the symbol "Strawberry A" is always displayed on the pay line A by the stop control because PB=1 on the center reel 110b. In this way, by stopping the symbol "Strawberry A" on the pay line A of the middle reel 110b, the winning combination "small combination 18" included in the winning type "batting order strawberry 1" has no possibility of winning, and only the winning combinations "small combination 2", "small combination 14", and "small combination 15" have the possibility of winning. Next, when the stop switch 120d is operated to stop the 4th reel 110d third according to the batting order 2, which is an incorrect operation mode, the symbol "cherry" constituting the winning combination "small combination 14" that has the largest number of symbol combinations of winning combinations that can be displayed on the pay line A is set to be preferentially displayed among the symbols "replay", "cherry", and "red 7" that are the targets of drawing. Then, the reel control means 306 performs stop control so that the symbol "cherry" is preferentially displayed on the pay line A in response to the operation of the stop switch 120d. Note that the symbol "cherry" is always able to be displayed on the pay line A by the stop control because PB=1 on the 4th reel 110d. In this way, by stopping the symbol "cherry" on the pay line A of the 4th reel 110d, the winning roles "small role 2" and "small role 15" included in the winning type "batting order strawberry 1" have no chance of winning, and only the winning role "small role 14" has the possibility of winning. In other words, by stopping the symbol "cherry" on the 4th reel 110d at PB=1, it is possible to avoid the winning of the winning role "small role 2" (correct role) with a payout number of 15 coins. Next, when the stop switch 120c is operated to stop the right reel 110c fourth according to the batting order 2, which is an incorrect operation mode, the symbol "cherry" to be drawn in is set to be displayed preferentially. Then, the reel control means 306 performs stop control so that the symbol "cherry" is displayed preferentially on the pay line A in response to the operation of the stop switch 120c. In addition, since the symbol "cherry" is PB=1 on the right reel 110c, it can always be displayed on the pay line A by the stop control. In this way, the winning combination "minor combination 14" is confirmed by the symbol "cherry" stopping on the pay line A of the right reel 110c. Here, by performing an operation according to the hitting order 2, which is an incorrect operation mode, it is possible to win the winning combination "minor combination 14" which can receive one coin, which is the minimum number of coins to be paid out, with PB=1. In addition, here, an example is given in which the symbol constituting the winning combination "minor combination 14" on the 4th reel 110d, which is stopped fourth, is the symbol "cherry" with PB=1. However, this is not the only case. As long as the possibility of winning is eliminated for all other winning combinations included in the winning type "Strawberry 1" at the third stop (winning combinations "Small combination 2", "Small combination 15", "Small combination 18", and "Small combination 19"), a PB ≠ 1 symbol may be used as the symbol that constitutes the winning combination "Small combination 14".

Next, as shown in FIG. 33, when the winning type "Strawberry 1" is won and the stop switch 120b is operated to stop the center reel 110b first according to the incorrect operation mode of batting order 7, the pattern "Bell" constituting the winning combination "Minor combination 19" that has the greatest number of winning combinations that can be displayed on the activated line A is set to be displayed preferentially among the symbols "Strawberry A", "Cherry", and "Bell" that are the targets of the draw. Then, the reel control means 306 performs stop control so that the symbol "Bell" is displayed preferentially on the activated line A in response to the operation of the stop switch 120b. Note that the symbol "Bell" is always displayed on the activated line A by the stop control because PB=1 on the center reel 110b. In this way, by stopping the symbol "bell" on the pay line A of the center reel 110b, the winning roles "small role 2", "small role 14", "small role 15", and "small role 18" included in the winning type "batting order strawberry 1" will no longer have the possibility of winning, and only the winning role "small role 19" will have the possibility of winning. In other words, by stopping the symbol "bell" on the center reel 110b at PB=1, it is possible to avoid the winning of the winning role "small role 2" (correct role) with a payout number of 15 coins. Next, when the stop switch 120a is operated to stop the left reel 110a second according to the batting order 7, which is an incorrect operation mode, the symbol "strawberry A" to be drawn in is set to be displayed preferentially. Then, the reel control means 306 controls the stop so that the symbol "strawberry A" is displayed preferentially on the pay line A in response to the operation of the stop switch 120a. In addition, the symbol "Strawberry A" is PB≠1 in the left reel 110a, and when operated randomly, it can only be displayed on the active line A by the stop control in 1/2 chance. Next, when the stop switch 120c is operated to stop the right reel 110c third according to the hitting order 7, which is an incorrect operation mode, the symbol "Strawberry A" to be drawn in is set to be displayed preferentially. Then, the reel control means 306 performs stop control so that the symbol "Strawberry A" is displayed preferentially on the active line A according to the operation of the stop switch 120c. In addition, since the symbol "Strawberry A" is PB=1 in the right reel 110c, it can always be displayed on the active line A by the stop control. Next, when the stop switch 120d is operated to stop the 4th reel 110d fourth according to the hitting order 7, which is an incorrect operation mode, the symbol "BAR" to be drawn in is set to be displayed preferentially. Then, the reel control means 306 performs stop control so that the symbol "BAR" is preferentially displayed on the pay line A in response to the operation of the stop switch 120d. Since the symbol "BAR" is PB=1 on the 4th reel 110d, the stop control ensures that the symbol can be displayed on the pay line A. Therefore, by performing an operation according to the hitting order 7, which is an incorrect operation mode, it is possible to win the winning role "small role 19", which can receive one coin, the minimum number of coins to be paid out, with a probability of 1/2. Here, an example is given in which the symbol constituting the winning role "small role 19" on the left reel 110a that is stopped second is the symbol "strawberry A" with PB≠1. However, since the possibility of winning all other winning roles included in the winning type "Strawberry 1" at the first stop (winning roles "Small Role 2", "Small Role 14", "Small Role 15", "Small Role 18") is eliminated, a symbol PB≠1 may be used as the symbol constituting the winning role "Small Role 19" on any of the reels 110 at the second, third, and fourth stops.

Here, we have explained the stop control for batting orders 1, 2, and 7 when the winning type "Batting Order Strawberry 1" is won, but for batting orders 3-6 and 13-24, the same stop control as for batting order 2 is used, and the player can receive one medal payout, and for batting orders 8-12, the same stop control as for batting order 7 is used, and the player can receive one medal payout with a 1/2 probability.

In this way, by adopting the winning type "Strawberry Batting Order" as the selected winning type and performing an auxiliary performance in the AT performance state, the expected number of coins to be won per unit of play in the AT performance state can be relatively increased compared to the non-AT performance state. Specifically, even if the winning type "Strawberry Batting Order" is won in the non-AT performance state, the auxiliary performance is hardly performed, so the player operates the stop switch 120 by deciding the batting order (for example, batting order 1 by pressing left) or operates it randomly, and the expected number of coins to be won per unit of play is (15 coins (correct role) x 1 + 1 coin x 17 + 1/2 coin x 6) / 24 ≒ 1.46 coins. On the other hand, if the winning type "Strawberry Batting Order" is won in the AT performance state, the auxiliary performance is executed, so the player can operate it by the correct operation mode (here, batting order 1), and the expected number of coins to be won per unit of play is 15 coins. In this way, by keeping the player in the AT performance state, the player can obtain a large gaming profit in a short period of time while reducing the consumption of medals, thereby increasing the player's motivation to play.

However, if the expected number of coins to be won per unit of play in the non-AT presentation state is set relatively low as described above in order to increase the expected number of coins to be won per unit of play in the AT presentation state, the player's investment will be unnecessarily large as he or she continues to remain in the non-AT presentation state. On the other hand, if one tries to increase the expected number of coins to be won per unit of play in the AT presentation state while suppressing the decrease in the expected number of coins to be won per unit of play in the non-AT presentation state, one has no choice but to set the probability of transitioning to the AT presentation state low or to set a period during which no lottery is held. This will result in a decrease in the frequency of transitions to the AT presentation state, which could result in the player feeling fatigued.

Therefore, we are considering increasing the difference in the expected number of coins to be won between the non-AT and AT presentation states while maintaining the player's motivation to play by relatively lowering the expected number of coins to be won per unit of play in the non-AT presentation state, without setting a low probability of transitioning to the AT presentation state or setting a period during which no lottery is held.

Figure 34 is an explanatory diagram for explaining the winning mode of the winning type "batting order chance role B". Here, the stop control will be explained by taking the left push and center push of the winning type "batting order chance role B1" as the winning type "batting order chance role B". As shown in the upper part of Figure 34, the winning type "batting order chance role B1" is a selection winning type that includes the winning role "small role 1" with a payout number of 15 coins and the winning roles "small role 33" and "small role 34" with a payout number of 1 coin overlapping. In this embodiment, when the winning type "batting order chance role B" is won, the correct operation mode (correct role) differs depending on whether it is in a non-AT performance state or an AT performance state. For example, in a non-AT performance state, it is possible to win a winning role (correct role) with a small payout number due to the correct operation mode, and in an AT performance state, it is possible to win a winning role (correct role) with a large payout number due to the correct operation mode. Here, we will describe an example in which a non-AT presentation state, i.e., a correct operation mode, can result in a winning combination (correct combination) with a small payout amount.

In this case, when setting the priority based on the types of pattern combinations that can be displayed on the active line A, the more types of pattern combinations of winning roles that can be displayed on the active line A, the higher the priority is set. Also, when setting the priority based on the number of medals paid out, the more the number of medals paid out for minor roles corresponding to the pattern combinations displayed on the active line A, the higher the priority is set.

As shown in FIG. 34, when the winning type "batting order chance role B1" is won and the stop switch 120a is operated to stop the left reel 110a first in accordance with the correct operation mode of pushing left, the drawn-in target symbol "REPLAY" is set to be displayed preferentially. Then, the reel control means 306 controls the stop so that the symbol "REPLAY" is displayed preferentially on the activated line A in response to the operation of the stop switch 120a. Note that since the symbol "REPLAY" is PB=1 on the left reel 110a, it can always be displayed on the activated line A by the stop control. Here, there is still a possibility of winning for all of the winning roles "small role 1", "small role 33", and "small role 34" included in the winning type "batting order chance role B1". Next, when the stop switch 120b is operated to stop the middle reel 110b second, the pattern "Strawberry A" constituting the winning combinations "small combination 33" and "small combination 34" that have the largest number of types of winning combinations that can be displayed on the active line A is set to be displayed preferentially among the patterns "Cherry" and "Strawberry A" to be drawn in. Then, the reel control means 306 performs stop control so that the pattern "Strawberry A" is displayed preferentially on the active line A in response to the operation of the stop switch 120b. Note that the pattern "Strawberry A" can always be displayed on the active line A by the stop control since PB=1 on the middle reel 110b. In this way, by stopping the pattern "Strawberry A" on the active line A of the middle reel 110b, the winning combination "small combination 1" included in the winning type "batting order chance combination B1" has no possibility of winning, and only the winning combinations "small combination 33" and "small combination 34" have the possibility of winning. That is, by stopping the symbol "Strawberry A" on the center reel 110b at PB=1, it is possible to avoid winning the winning combination "Small Role 1" with a payout of 15 coins. Next, when the stop switch 120c is operated to stop the right reel 110c third, the symbol "Replay" constituting the winning combination "Small Role 34" to be drawn in is set to be preferentially displayed. Then, the reel control means 306 performs stop control so that the symbol "Replay" is preferentially displayed on the pay line A in response to the operation of the stop switch 120c. Note that the symbol "Replay" can always be displayed on the pay line A by the stop control since PB=1 on the right reel 110c. Next, when the stop switch 120d is operated to stop the 4th reel 110d fourth, the symbol "BAR" constituting the winning combination "Small Role 33" to be drawn in is set to be preferentially displayed. Then, the reel control means 306 performs stop control so that the symbol "BAR" is preferentially displayed on the pay line A in response to the operation of the stop switch 120d. Since the symbol "BAR" is PB=1 on the 4th reel 110d, the stop control ensures that the symbol "BAR" is displayed on the pay line A. In this way, the winning combinations "small combination 33" and "small combination 34" are both confirmed as winning combinations when the symbol "BAR" stops on the pay line A of the 4th reel 110d. Here, by performing an operation by pressing the left button, the winning combinations "small combination 33" and "small combination 34", each of which can receive a payout of one coin, which is the minimum number of coins to be paid out, are won with PB=1, and the player can receive the payout of two coins (1 coin + 1 coin).

In addition, by ensuring that the winning combinations "small combination 33" and "small combination 34" are won with PB=1, the player can be clearly informed that the winning combination that has been won is the winning combination "batting order chance combination B," and can expect a gaming profit based on the winning combination "batting order chance combination B."

Next, as shown in FIG. 34, when the winning type "batting order chance role B1" is won and the stop switch 120b is operated to stop the center reel 110b first according to the incorrect operation mode of the center push, the pattern "cherry" constituting the winning role "small role 1" which has the largest number of medals paid out, 15, is set to be displayed preferentially among the patterns "cherry" and "strawberry A" to be drawn. Then, the reel control means 306 performs stop control so that the pattern "cherry" is displayed preferentially on the effective line A in response to the operation of the stop switch 120b. Note that the pattern "cherry" can always be displayed on the effective line A by the stop control, since PB=1 on the middle reel 110b. In this way, by the pattern "cherry" stopping on the effective line A of the middle reel 110b, the winning roles "small role 33" and "small role 34" included in the winning type "batting order chance role B1" have no chance of winning, and only the winning role "small role 1" has the possibility of winning. That is, by stopping the symbol "cherry" on the center reel 110b at PB=1, it is possible to avoid winning the winning symbols "small symbol 33" and "small symbol 34" each of which has a payout of one coin. Next, when the stop switch 120a is operated to stop the left reel 110a second, the symbol "replay" to be drawn in is set to be preferentially displayed. Then, the reel control means 306 performs stop control so that the symbol "replay" is preferentially displayed on the pay line A in response to the operation of the stop switch 120a. Note that the symbol "replay" is always displayed on the pay line A by the stop control because PB=1 on the left reel 110a. Next, when the stop switch 120c is operated to stop the right reel 110c third, the symbol "replay" to be drawn in is set to be preferentially displayed. Then, the reel control means 306 performs stop control in response to the operation of the stop switch 120c so that the symbol "REPLAY" is preferentially displayed on the pay line A. Since the symbol "REPLAY" is PB=1 on the right reel 110c, it can always be displayed on the pay line A by the stop control. Next, when the stop switch 120d is operated to stop the 4th reel 110d fourth, the symbol "white circle" to be drawn in is set to be preferentially displayed. Then, the reel control means 306 performs stop control in response to the operation of the stop switch 120d so that the symbol "white circle" is preferentially displayed on the pay line A. Since the symbol "white circle" is PB=1 on the 4th reel 110d, it can always be displayed on the pay line A by the stop control. In this way, the winning combination "minor combination 1" is confirmed by the stop of the symbol "white circle" on the pay line A of the 4th reel 110d. Here, by pressing the center button, it is possible to win the "minor prize 1" with PB=1, which can pay out 15 medals, the maximum number of medals that can be paid out, and the player can receive 15 medals.

Here, we have explained the stop control for the left and center pushes when the winning type "Batting Order Chance B1" is won, but for the right and 4th pushes, the same stop control is performed as for the center push, and the player can receive the payout of 15 medals.

As mentioned above, when the winning type "batting order chance role B" is won, the correct operation mode (correct role) differs depending on whether the state is non-AT or AT. In particular, in the non-AT state, only two coins are paid out if the player operates in the correct operation mode, but 15 coins are paid out if the player operates in the incorrect operation mode.

The reason why the operation mode that produces a winning combination with a smaller payout number can be used as the correct operation mode for the following reasons is that when the center reel 110b stops, the other winning combinations (the winning combination "minor win 1" in FIG. 34) can only have one type of winning combination that can be displayed on the active line A in the arrangement, whereas the target winning combinations (the winning combinations "minor win 33" and "minor win 34" in FIG. 34) can only be displayed simultaneously (overlapped) on the active line A in the arrangement, and there are two types of winning combinations that can be displayed on the active line A, which is more than the other winning combinations, and it is believed that the player can play the game to his advantage. This auxiliary effect allows the player to display multiple winning combinations on the active line A.

In this way, compared to the expected number of coins to be won per unit of play in an AT presentation state, if the player operates randomly in a non-AT presentation state, the expected number of coins to be won per unit of play will be relatively high (reducing the investment amount). However, by deliberately implementing an auxiliary presentation that produces a winning combination with a small payout amount and adopting a gameplay characteristic that relatively lowers the expected number of coins to be won per unit of play, it is possible to increase the difference in the expected number of coins to be won between the non-AT presentation state and the AT presentation state, and to increase the player's motivation to play.

However, if the payout number is small when the auxiliary performance is followed in a non-AT performance state, and the payout number is large when the auxiliary performance is ignored and a different operation is performed, there is a risk that a player will intentionally not follow the auxiliary performance. Therefore, when the winning type "batting order chance role B" is won, a lottery is held for the AT performance state (CZ performance state), and the game is set as a so-called ceiling consumption game (or the number of games to reach the ceiling is shortened), and if the auxiliary performance is not followed, it is specified to be restricted. In other words, when the winning type "batting order chance role B" is won in a non-AT performance state, if the player operates in the correct operation mode according to the auxiliary performance, a lottery is held for the AT performance state, although the payout number is small, and the game can be set as a so-called ceiling consumption game (or the number of games to reach the ceiling is shortened). On the other hand, when the player wins the winning type "batting order chance role B" in a non-AT performance state, if the player does not follow the auxiliary performance and operates in an incorrect operation mode, the number of payouts is large, but the player cannot receive the lottery for the AT performance state, and the game cannot be considered as a so-called ceiling consumption game (or the number of games to reach the ceiling can be shortened) (the number of games to reach the ceiling is extended). In other words, in order to prevent the player from ignoring the auxiliary performance, a game profit that is more advantageous than operating in an incorrect operation mode, for example, a lottery for the AT performance state, is granted. Since such a game characteristic is adopted, when the winning type "batting order chance role B" is won in a non-AT performance state, the operation mode that pays out a small number of coins can be considered as a correct operation mode, and the operation mode that pays out a large number of coins can be considered as an incorrect operation mode.

The lottery for the AT performance state is conducted after the third stop when it is confirmed that the player has followed the auxiliary performance in the non-AT performance state (or the winning combinations "minor combination 33" and "minor combination 34" have been won, or two coins have been paid out). However, this is not the only case. In the non-AT performance state, the lottery for the AT performance state may be conducted in response to the operation of the start switch 118, and if it is confirmed that the player has not followed the auxiliary performance, the lottery result may be cancelled.

With this configuration, the expected number of coins to be won per unit of play in a non-AT presentation state can be made relatively lower through auxiliary effects compared to the expected number of coins to be won per unit of play in an AT presentation state, making it possible to increase the difference in the expected number of coins to be won between the non-AT presentation state and the AT presentation state while maintaining the player's motivation to play.

In the above example, when the winning type "batting order chance role B" is won in a non-AT performance state, the operation mode with a small number of payouts is the correct operation mode, and the operation mode with a large number of payouts is the incorrect operation mode. However, when the winning type "batting order chance role B" is won in an AT performance state, there is no restriction on the selection of the AT performance state, and the operation mode with a large number of payouts is the correct operation mode, and the operation mode with a small number of payouts is the incorrect operation mode. Therefore, when the winning type "batting order chance role B" is won in an AT performance state, an auxiliary performance is executed, and the player can operate by the correct operation mode (in the example of FIG. 34, other than left push, for example, center push), and the expected number of coins to be won per unit play is 15 coins (correct role), which is the maximum number of coins to be paid out.

In the example of the winning type "batting order chance role B" explained using FIG. 34, when the center reel 110b stops, the winning roles "small role 33" and "small role 34" which have a smaller number of payouts have more number of pattern combinations (2) that can be displayed on the active line A than the winning role "small role 1" which has a larger number of payouts has more number of pattern combinations (1) that can be displayed on the active line A. Therefore, the operation mode which makes the winning roles "small role 33" and "small role 34" win is auxiliary performed as the correct operation mode. Therefore, since two winning roles are won at the same time, at least one payout for the winning role "small role 33" and one payout for the winning role "small role 34" will be paid out, as explained in FIG. 34, in total, two coins will be paid out.

Here, if the number of medals paid out is two when the specified number required for a game is three, even if two small winning symbols have been won, the next game cannot start unless one more medal is bet on top of the medals paid out. Therefore, let's say that the number of medals paid out for each of the two winning symbols is set to two instead of one. In this case, the specified number of three medals can be bet out of the four medals paid out when two small winning symbols have been won, and the next game can be started. However, if the number of medals paid out is four, the difference with the 15 medals paid out when an incorrect operation is performed becomes smaller, and the effect of increasing the difference in the expected number of medals won between the non-AT presentation state and the AT presentation state is weakened.

Here, the payout numbers for the two minor roles are made different, for example, one winning role pays out 1 coin and the other winning role pays out 2 coins, making the total payout number an odd number, for example 3 coins.

Figure 35 is an explanatory diagram for explaining the winning mode of the winning type "batting order chance role A". Here, the stop control will be explained by taking the left push and center push of the winning type "batting order chance role A1" as the winning type "batting order chance role A". As shown in the upper part of Figure 35, the winning type "batting order chance role A1" is a selection winning type that includes the winning role "small role 1" with a payout number of 15, the winning role "small role 35" with a payout number of 1, and the winning role "small role 36" with a payout number of 2. In this embodiment, as in Figure 34, when the winning type "batting order chance role A" is won, the correct operation mode (correct role) differs depending on whether it is in a non-AT performance state or an AT performance state. For example, in a non-AT performance state, it is possible to win a winning role (correct role) with a small payout number due to the correct operation mode, and in an AT performance state, it is possible to win a winning role (correct role) with a large payout number due to the correct operation mode. Here, we will describe an example in which a non-AT presentation state, that is, a correct operation mode makes it possible to win a winning role (correct role) with a small payout amount.

Here, as in FIG. 34, when setting the priority based on the types of pattern combinations that can be displayed on the active line A, the priority is set to be higher the more types of pattern combinations of winning roles that can be displayed on the active line A, and when setting the priority based on the number of medals paid out, the priority is set to be higher the more the number of medals paid out for the minor roles corresponding to the pattern combinations displayed on the active line A.

As shown in FIG. 35, when the winning type "batting order chance role A1" is won and the stop switch 120a is operated to stop the left reel 110a first according to the correct operation mode of pushing left, the symbols "red 7" or "bell" constituting the winning roles "small role 35" and "small role 36", which have the largest number of symbol combinations of winning roles that can be displayed on the activated line A, are set to be displayed preferentially among the symbols "replay", "red 7", and "bell" that are the targets of drawing. Then, the reel control means 306 performs stop control so that the symbol "red 7" or "bell" is displayed preferentially on the activated line A according to the operation of the stop switch 120a. Note that the arrangement of the symbols "red 7" and "bell" is PB=1 on the left reel 110a when both symbols are combined, so that one of the symbols can always be displayed on the activated line A by the stop control. In this way, when the symbol "red 7" or "bell" stops on the pay line A of the left reel 110a, the winning role "small role 1" included in the winning type "batting order chance role A1" has no possibility of winning, and only the winning roles "small role 35" and "small role 36" have the possibility of winning. In other words, by stopping the symbol "bell" on the left reel 110a at PB=1, it is possible to avoid the winning of the winning role "small role 1" with a payout number of 15 coins. Next, when the stop switch 120b is operated to stop the center reel 110b second, the symbol "bell" to be drawn in is set to be displayed preferentially. Then, the reel control means 306 performs stop control so that the symbol "bell" is displayed preferentially on the pay line A in response to the operation of the stop switch 120b. Note that the symbol "bell" is always displayed on the pay line A by the stop control because PB=1 on the center reel 110b. Next, when the stop switch 120c is operated to stop the right reel 110c third, the symbol "bell" constituting the winning combination "minor combination 35" to be drawn is set to be preferentially displayed. Then, the reel control means 306 performs stop control so that the symbol "bell" is preferentially displayed on the activated line A in response to the operation of the stop switch 120c. Note that the symbol "bell" can always be displayed on the activated line A by the stop control since PB=1 in the right reel 110c. Next, when the stop switch 120d is operated to stop the 4th reel 110d fourth, the symbol "red 7" constituting the winning combination "minor combination 36" to be drawn is set to be preferentially displayed. Then, the reel control means 306 performs stop control so that the symbol "red 7" is preferentially displayed on the activated line A in response to the operation of the stop switch 120d. In addition, since the symbol "red 7" has PB=1 on the 4th reel 110d, it can always be displayed on the pay line A by the stop control. In this way, when the symbol "red 7" stops on the pay line A of the 4th reel 110d, both the winning combination "minor combination 35" and the winning combination "minor combination 36" are confirmed. Here, by performing an operation by pressing the left button, the winning combination "minor combination 35" which can receive the minimum payout of 1 coin, and the winning combination "minor combination 36" which can receive the payout of 2 coins are won with PB=1, and the player can receive the payout of 3 coins (1 coin + 2 coins).

In addition, by ensuring that the winning combinations "small combination 35" and "small combination 36" are won with PB=1, the player can be clearly informed that the winning combination that has been won is the winning combination "batting order chance combination A," and can expect a gaming profit based on the winning combination "batting order chance combination A."

Next, as shown in FIG. 35, when the winning type "batting order chance role A1" is won and the stop switch 120b is operated to stop the center reel 110b first according to the incorrect operation mode of the center push, the pattern "cherry" constituting the winning role "small role 1" which has the largest number of medals paid out, 15, is set to be displayed preferentially among the patterns "cherry" and "bell" to be drawn. Then, the reel control means 306 performs stop control so that the pattern "cherry" is displayed preferentially on the effective line A in response to the operation of the stop switch 120b. Note that the pattern "cherry" can always be displayed on the effective line A by the stop control, since PB=1 on the middle reel 110b. In this way, by the pattern "cherry" stopping on the effective line A of the middle reel 110b, the winning roles "small role 35" and "small role 36" included in the winning type "batting order chance role A1" have no chance of winning, and only the winning role "small role 1" has the possibility of winning. That is, by stopping the symbol "cherry" on the center reel 110b at PB=1, it is possible to avoid winning the winning symbol "minor symbol 35" with one payout and the winning symbol "minor symbol 36" with two payouts. Then, when the stop switch 120a is operated to stop the left reel 110a second, the symbol "replay" to be drawn in is set to be preferentially displayed. Then, the reel control means 306 performs stop control so that the symbol "replay" is preferentially displayed on the pay line A in response to the operation of the stop switch 120a. Note that the symbol "replay" is always displayed on the pay line A by the stop control because PB=1 on the left reel 110a. Then, when the stop switch 120c is operated to stop the right reel 110c third, the symbol "replay" to be drawn in is set to be preferentially displayed. Then, the reel control means 306 performs stop control in response to the operation of the stop switch 120c so that the symbol "REPLAY" is preferentially displayed on the pay line A. Since the symbol "REPLAY" is PB=1 on the right reel 110c, it can always be displayed on the pay line A by the stop control. Next, when the stop switch 120d is operated to stop the 4th reel 110d fourth, the symbol "white circle" to be drawn in is set to be preferentially displayed. Then, the reel control means 306 performs stop control in response to the operation of the stop switch 120d so that the symbol "white circle" is preferentially displayed on the pay line A. Since the symbol "white circle" is PB=1 on the 4th reel 110d, it can always be displayed on the pay line A by the stop control. In this way, the winning combination "minor combination 1" is confirmed by the stop of the symbol "white circle" on the pay line A of the 4th reel 110d. Here, by pressing the center button, it is possible to win the "minor prize 1" with PB=1, which can pay out 15 medals, the maximum number of medals that can be paid out, and the player can receive 15 medals.

Here, we have explained the stop control for the left and center presses when the winning type "Batting Order Chance A1" is won, but for the right and 4th presses, the same stop control is performed as for the center press, and the player can receive a payout of 15 medals.

In this way, compared to the expected number of coins to be won per unit of play in an AT presentation state, if the player operates randomly in a non-AT presentation state, the expected number of coins to be won per unit of play will be relatively high (reducing the amount of investment). However, by deliberately using an auxiliary presentation that produces a winning combination with a small payout amount and adopting a gameplay characteristic that relatively lowers the expected number of coins to be won per unit of play, it is possible to increase the difference in the expected number of coins to be won between the non-AT presentation state and the AT presentation state, and increase the player's motivation to play.

Here, when the winning type "Batting Order Chance Role A" is won in a non-AT performance state, if the player performs the correct operation mode according to the auxiliary performance, the winning role "Small Role 35" with a payout of one coin and the winning role "Small Role 36" with a payout of two coins will both be won, and a total of three medals can be paid out. In this way, by setting the total payout number to three coins, the suppression of the effect of increasing the difference in the expected number of coins between the non-AT performance state and the AT performance state is minimized, and the player's motivation to play is increased, while the player can start the next game without having to go through the trouble of betting additional medals.

Here, an example has been given in which, in an AT presentation state, when the winning type "Batting Order Strawberry" (first selected winning type) is won, an operation (second operation) is notified that will result in a winning role "Small Role 2" (second role) that can receive a maximum payout of 15 coins, and when the winning type "Batting Order Chance Role" (second selected winning type) is won, an operation (fourth operation) is notified that will result in a winning role "Small Role 1" (fourth role) that can receive a maximum payout of 15 coins, and when the winning type "Batting Order Chance Role" (second selected winning type) is won, an operation (third operation) is notified that will result in a winning role "Small Role 33", "Small Role 34", "Small Role 35", "Small Role 36" (third role) that can receive a payout of less than 15 coins, in a non-AT presentation state. In this case, the payout number (payout) for the high-payout winning role "Small Role 2" (second role) in the winning type "Batting Order Strawberry" (first selected winning type) and the high-payout winning role "Small Role 1" (fourth role) in the winning type "Batting Order Chance Role" (second selected winning type) are equal, 15 coins.

In this way, by making the number of high payout coins equal for the winning type "Batting Order Strawberry" and the winning type "Batting Order Chance Role", the processing load when paying out high payout coins in the AT performance state, etc., can be reduced. For example, as described above, if the AT performance state is a difference number management type, whether the winning type "Batting Order Strawberry" or the winning type "Batting Order Chance Role" is won, it will be sufficient to count the difference number of 12 coins (maximum payout number of 15 coins - specified number of 3 coins) in common.

As described above, in the AT performance state, not only when the winning type "Strawberry Batting Order" is won, but also when the winning type "Batting Order Chance Role" is won, an auxiliary performance is performed that can win a winning role that can receive a payout of 15 coins (for example, the winning role "Small Role 1"). In other words, the winning type that can obtain a high gaming profit by performing the auxiliary performance is not only the winning type "Strawberry Batting Order" but also the winning type "Batting Order Chance Role".

With this configuration, players can receive 15 coins not only when they win the "Batting Order Strawberry" prize type, but also when they win the "Batting Order Chance" prize type, allowing them to earn a lot of gaming profits in a short period of time.

In this case, not only the auxiliary effects when the winning type "Bat Order Strawberry" is won, but also the auxiliary effects when the winning type "Bat Order Chance Role" is won are counted as gaming profits in the AT performance state. For example, in the case of difference number management as in this embodiment, the performance state control means 314 counts the difference number of 12 coins (maximum payout number 15 coins - specified number 3 coins) when the winning type "Bat Order Strawberry" is won and 15 coins are paid out through the auxiliary performance, and also counts the difference number of 12 coins (maximum payout number 15 coins - specified number 3 coins) when the winning type "Bat Order Chance Role" is won and 15 coins are paid out through the auxiliary performance. The performance state control means 314 continues the AT performance state until the difference number becomes equal to or greater than the specified difference number, and ends the AT performance state when the difference number becomes equal to or greater than the specified difference number.

Here, an example of difference number management has been described, but not limited to this case, in various management modes of the AT performance state, not only the auxiliary performance when the winning type "batting order strawberry" is won, but also the auxiliary performance when the winning type "batting order chance role" is won, are counted as the gaming profit of the AT performance state. Specifically, the performance state control means 314 counts not only the auxiliary performance when the winning type "batting order strawberry" is won, but also the auxiliary performance when the winning type "batting order chance role" is won, as the gaming profit of the AT performance state, not only in the case where the AT performance state is managed by the consumption of various game opportunities that can receive auxiliary performance, for example, the number of payouts (payout number management), but also in the case where the AT performance state is managed by the number of navigation times that can win a winning role that receives a payout of 15 coins (navigation number management). In the AT performance state, the performance state control means 314 counts the number of payouts of the winning combination in payout number management, continues the AT performance state until the number of payouts reaches or exceeds the predetermined number, and ends the AT performance state when the number of payouts reaches or exceeds the predetermined number. Similarly, in the AT performance state, the performance state control means 314 counts the number of navigations of the winning combination in navigation number management, continues the AT performance state until the number of navigations reaches or exceeds the predetermined number, and ends the AT performance state when the number of navigations reaches or exceeds the predetermined number. In addition, in the AT performance state where an auxiliary performance can be received, the performance state control means 314 performs a lottery to add the difference in the number of payouts, the number of payouts, or the number of navigations, and when the lottery is won, the difference in the number of payouts, the number of payouts, or the number of navigations is increased (changes the end condition).

In addition, in the non-AT performance state, if the winning type "Bat Order Strawberry" is won, the auxiliary performance is not performed, so the expected number of coins to be won per unit of play is (15 coins (correct role) x 1 + 1 coin x 17 + 1/2 coin x 6) / 24 ≒ 1.46 coins. If the winning type "Bat Order Chance Role A" is won, the auxiliary performance is performed and the expected number of coins to be won per unit of play is 3 coins. If the winning type "Bat Order Chance Role B" is won, the auxiliary performance is performed and the expected number of coins to be won per unit of play is 2 coins. On the other hand, in the AT performance state, whether the winning type "Bat Order Strawberry" or the winning type "Bat Order Chance Role" is won, the auxiliary performance is performed, so the expected number of coins to be won per unit of play is 15 coins. In this way, by setting the expected number of coins to be won per unit of play in the non-AT performance state low and setting the expected number of coins to be won per unit of play in the AT performance state as the maximum payout number, the difference between the expected number of coins to be won per unit of play between the two can be made large. Therefore, by keeping the player in the AT performance state, the player can reduce medal consumption while obtaining a large gaming profit in a short period of time, thereby increasing the player's motivation to play.

In addition, when the winning type "Strawberry in Batting Order" (first selected winning type) is won, if the winning role "Small Role 2" (second role) that can receive the maximum payout number of 15 coins is won, at least three symbols are displayed linearly on any line in the symbol display window 108. For example, in the example of FIG. 33, a predetermined symbol combination (here, the symbol combination of "Strawberry A", "Strawberry A", and "Strawberry A", or the symbol combination of "Strawberry B", "Strawberry A", and "Strawberry A") is displayed linearly in the upper row of the left reel 110a, the middle row of the middle reel 110b, and the lower row of the right reel 110c in the symbol display window 108. Also, when the winning type "batting order chance role" (second selection winning type) is won, if the winning role "minor role 1" (fourth role) that can receive the maximum payout number of 15 coins is won, at least three symbols are displayed linearly on any line in the symbol display window 108, just like the winning type "batting order strawberry". For example, in the example of Figures 34 and 35, a predetermined symbol combination (here, the symbol combination of the symbols "Strawberry A", "Strawberry A", and "Strawberry A", or the symbol combination of the symbols "Strawberry B", "Strawberry A", and "Strawberry A") is displayed linearly on the upper row of the left reel 110a, the upper row of the middle reel 110b, and the upper row of the right reel 110c in the symbol display window 108. In this way, in this embodiment, the symbol combination displayed linearly on one of the lines in the symbol display window 108 when the winning combination "minor role 2" (second role) is won is the same as the symbol combination displayed linearly on one of the lines in the symbol display window 108 when the winning combination "minor role 1" (fourth role) is won.

With this configuration, when the AT performance state is in effect, in both the winning type "Batting Order Strawberry" and the winning type "Batting Order Chance Role", the same pattern combination is displayed linearly in the pattern display window 108, and the maximum number of payout coins, 15 coins, can be paid out. Therefore, in the AT performance state, the player can recognize that the maximum number of payout coins has been obtained by visually checking the pattern combination displayed linearly, without being aware of whether the winning type that has been won is the winning type "Batting Order Strawberry" or the winning type "Batting Order Chance Role".

In addition, when symbol combinations displayed in a straight line are said to be equal, this does not only mean that the symbols that make up the symbol combination displayed in a straight line are completely equal, but also includes cases where the symbols that make up the symbol combination displayed in a straight line are different symbols that the player can recognize as the same minor winning combination, such as the symbol "Strawberry A" and the symbol "Strawberry B."

In addition, the symbol combination corresponding to the winning role "minor role 2" (second role) which can receive the maximum payout number of 15 coins constituting the winning type "batting order strawberry" (first selected winning type) and the symbol combination corresponding to the winning role "minor role 1" (fourth role) which can receive the maximum payout number of 15 coins when the winning type "batting order chance role" (second selected winning type) is won, i.e., the condition devices for both can be made equal.

With this configuration, in the AT presentation state, when either the winning type "Batting Order Strawberry" or the winning type "Batting Order Chance Role" is won, the same symbol combination is displayed on the active line A, and the maximum number of payout coins, 15 coins, can be paid out. Therefore, in the AT presentation state, the player can recognize that the maximum number of payout coins has been obtained by visually checking the symbol combination displayed on the active line A, without being aware of whether the winning type that was won was the winning type "Batting Order Strawberry" or the winning type "Batting Order Chance Role."

Figure 36 is a diagram showing the number of places in the winning type lottery table. In Figure 36, the number of places in the winning type lottery table shown in Figure 7 will be described in particular. Here, the winning types are broadly categorized into a number of types, for example, the winning type "Batting Order Strawberry" (first selection winning type), the winning type "Batting Order Chance Role" (second selection winning type), and the winning type "Replay" (replay winning type). For the winning type "Batting Order Strawberry", the number of places is 1870, which is evenly allocated to the winning types "Batting Order Strawberry 1" to "Batting Order Strawberry 24" in winning areas 4 to 27. Therefore, the total number of places for the winning type "Batting Order Strawberry" is 1870 x 24 = 44880. In addition, for the winning type "batting order chance role", the number of places is evenly allocated to the winning types "batting order chance role A1" to "batting order chance role A4" in the winning areas 28 to 31, and the number of places is evenly allocated to the winning types "batting order chance role B1" to "batting order chance role B4" in the winning areas 32 to 35. Therefore, the total number of places for the winning type "batting order chance role" is 128 x 4 + 612 x 4 = 2960. In addition, as for the winning type "replay", the winning type "normal replay 1" in the winning area 36 is assigned a number of 4 in the non-internal game state and a number of 8 in the RBB internal game state, the winning type "normal replay 2" in the winning area 37 is assigned a number of 3524, the winning type "normal replay 3" in the winning area 38 is assigned a number of 1400, the winning type "normal replay 4" in the winning area 39 is assigned a number of 1200, and the winning type "normal replay 5" in the winning area 40 is assigned a number of 8. 00 is assigned, the winning type "Normal Replay 6" in winning area 41 is assigned a number of 500, the winning type "Chance Replay" in winning area 42 is assigned a number of 400, the winning type "Weak Bell" in winning area 43 is assigned a number of 800, the winning type "Strong Bell" in winning area 44 is assigned a number of 90, the winning type "Strong Cherry 1" in winning area 45 is assigned a number of 20, and the winning type "Strong Cherry 2" in winning area 46 is assigned a number of 200. Therefore, the total number of places for the winning type "Replay" is 8938 in the non-internal play state and 8942 in the RBB internal play state.

The number of winning types "Strawberry Batting Order", "Chance Batting Order", and "Replay" that are broadly classified in this way has the following relationship: "Strawberry Batting Order" > "Chance Batting Order", and "Replay" > "Chance Batting Order". This is for the following reason. In other words, the "Chance Batting Order" winning type is accompanied by an auxiliary performance in a non-AT performance state, and the player operates the stop switch 120 according to the auxiliary performance in order to receive a lottery for the AT performance state. However, if the frequency of the auxiliary performance is increased too much in a non-AT performance state, the player may be forced to operate in the correct operation mode, and waste time playing the game. Here, the frequency of the auxiliary performance in a non-AT performance state can be suppressed by making the number of winning types "Strawberry Batting Order" smaller than the number of winning types "Strawberry Batting Order" and "Replay".

In addition, generally, a role with a high gaming profit, such as a high probability of winning the AT performance state, may be called a rare role. In this embodiment, the winning type "Weak Cherry 1" in winning area 3, the winning type "Chance Replay" in winning area 42, the winning type "Weak Bell" in winning area 43, the winning type "Strong Bell" in winning area 44, the winning type "Strong Cherry 1" in winning area 45, the winning type "Strong Cherry 2" in winning area 46, and the winning type "RBB + Weak Cherry 2" in winning area 47 correspond to rare roles. A winning type that includes such a rare role may be called a winning type "rare role" (rare role winning type). The winning type "Weak Cherry 1" in winning area 3, which is a rare role, is assigned a number of 220, the winning type "Chance Replay" in winning area 42 is assigned a number of 400, the winning type "Weak Bell" in winning area 43 is assigned a number of 800, the winning type "Strong Bell" in winning area 44 is assigned a number of 90, the winning type "Strong Cherry 1" in winning area 45 is assigned a number of 20, the winning type "Strong Cherry 2" in winning area 46 is assigned a number of 200, and the winning type "RBB + Weak Cherry 2" in winning area 47 is assigned a number of 60. Therefore, the total number of winning types corresponding to rare roles is 1790.

The number of winning types corresponding to such rare roles and the number of winning types "Batting Order Strawberry" and "Batting Order Chance Role" broadly categorized above have the following relationship: winning type "Batting Order Strawberry" > winning type "Batting Order Chance Role", and winning type "Batting Order Chance Role" > winning type corresponding to rare roles. This is for the following reasons. In other words, by making the number of winning types "Batting Order Chance Role" smaller than the number of winning types "Batting Order Strawberry", it is possible to suppress the frequency of auxiliary performance in non-AT performance states. Also, by making the number of rare roles smaller than both the number of winning types "Batting Order Chance Role" and "Batting Order Strawberry", it is possible to reduce the frequency of rare roles, and increase the probability of winning the AT performance state, thereby increasing the gaming profit.

In addition, different gameplay characteristics can be created by adjusting the number of symbols placed on the winning type lottery tables shown in Figures 6 and 7.

Figure 37 is a diagram showing the number of places in the winning type lottery table. In this figure, winning areas 4 to 31 in the RBB internal game state in the winning type lottery table shown in Figure 6 are extracted, and a different number of places than in Figure 7 is associated with them. Here, the number of places for each winning type of "Strawberry" winning type in winning areas 4 to 27 is not equal, and the purpose is to make the number of places for the winning types "Strawberry 1" to "Strawberry 6" in which the batting order (1 to 6) that causes the left reel 110a to stop first is the correct operation mode smaller than the other batting orders (7 to 24).

In the non-AT performance state, even if the winning type "Strawberry Batting Order" is won, the auxiliary performance is not executed, so the player decides the batting order by himself or randomly. In addition, in the case of a specification in which the player is advantageous if the left reel 110a is operated in the batting order that stops first (batting order 1 to 6), the player operates the left reel 110a in the batting order that stops first (batting order 1 to 6). In this case, if the number of winning types "Strawberry Batting Order 1" to "Strawberry Batting Order 6" is set smaller than the number of other winning types "Strawberry Batting Order 7" to "Strawberry Batting Order 24", the expected number of winning coins per unit of play in the non-AT performance state can be reduced. In addition, in the non-AT performance state, if the winning type "Strawberry Batting Order Chance Role A" is won, the auxiliary performance is executed as described above, and the player operates the stop switch 120 according to the auxiliary performance, so the expected number of winning coins per unit of play is three coins. Here, the number of each winning type of "Batting Order Chance Role A" is evenly distributed, so the frequency of the auxiliary effects appearing is equal.

On the other hand, in the AT performance state, if the winning type "Bat Order Ichigo" is won, the auxiliary performance is executed, and the expected number of coins to be won per unit of play is 15 coins. However, since the number of winning types "Bat Order Ichigo 1" to "Bat Order Ichigo 6" placed is smaller than the number of winning types "Bat Order Ichigo 7" to "Bat Order Ichigo 24" placed, the frequency of the auxiliary performance is biased. Therefore, this bias in the auxiliary performance is absorbed by the winning type "Bat Order Chance Role A". In other words, in the AT performance state, if the winning type "Bat Order Chance Role A1" is won, any of the batting orders 7 to 24 are announced evenly as the auxiliary performance, and if the winning types "Bat Order Chance Role A2" to "Bat Order Chance Role A4" are won, any of the batting orders 1 to 6 are announced evenly as the auxiliary performance. In this case, the expected number of coins to be won per unit of play is 15 coins. However, the probability that any of batting orders 1 to 6 will be announced as an auxiliary effect is nine times the probability that any of batting orders 7 to 24 will be announced. Therefore, by adjusting the ratio of the number of winning types "Strawberry Batting Order" and "Batting Order Chance A" placed, it is possible to equalize the frequency of appearance of auxiliary effects in the AT performance state.

Specifically, if the number of winning types "Batting Order Ichigo 1" to "Batting Order Ichigo 6" is α, the number of winning types "Batting Order Ichigo 7" to "Batting Order Ichigo 24" is β, and the number of winning types "Batting Order Chance Role A1" to "Batting Order Chance Role A4" is γ, then each number is set so that α + γ/2 = β + γ/18 holds. For example, as shown in Figure 37, if α = 1790, β = 1870, and γ = 180 are set, then α + γ/2 = β + γ/18 holds. By setting in this way, in the AT performance state, the probability that any one of batting orders 1 to 6 is announced as the auxiliary performance is (α+γ/2)/65536=1880/65536, and the probability that any one of batting orders 7 to 24 is announced as the auxiliary performance is (β+γ/18)/65536=1880/65536, and it can be understood that the frequency of appearance of the auxiliary performance in the AT performance state is equal. As described above, in the AT performance state, when either the winning type "batting order strawberry" or the winning type "batting order chance role" is won, the same pattern combination can be displayed linearly in the pattern display window 108 while paying out 15 coins, which is the maximum number of payout coins. Therefore, in the AT performance state, the player can recognize that the maximum number of payout coins has been obtained by visually checking the pattern combination displayed linearly, without being aware of whether the winning type that has been won is the winning type "batting order strawberry" or the winning type "batting order chance role". In addition, the number of each winning type of the "batting order chance role A" is evenly distributed to 180, so the frequency of the batting order in the auxiliary performance is equal.

This configuration makes it possible to equalize the frequency of appearance of the batting order in the auxiliary effects in the AT performance state and the frequency of appearance of the batting order in the auxiliary effects in the non-AT performance state, while making the number of placements for the winning types "Batting Order Strawberry 1" to "Batting Order Strawberry 6", in which the batting order (batting orders 1 to 6) that first stops the left reel 110a is the correct operation mode, smaller than the number of placements for the other winning types "Batting Order Strawberry 7" to "Batting Order Strawberry 24", thereby reducing the expected number of coins won per unit of play in the non-AT performance state.

Although the preferred embodiment of the present invention has been described above with reference to the attached drawings, it goes without saying that the present invention is not limited to such an embodiment. It is clear that a person skilled in the art can come up with various modified or revised examples within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present invention.

For example, in the above-mentioned embodiment, as explained using FIG. 33, the winning roles "small role 14", "small role 15", "small role 18", and "small role 19" (all first roles) with a payout of 1 coin overlap with the winning role "small role 2" (second role) with a payout of 15 coins, and the winning role "small role 14", "small role 15", "small role 18", and "small role 19" can be won by batting order 2 to 24 (first operation), which are incorrect operation modes, and the winning type "batting order strawberry" (first selected winning type) set to be able to win the winning role "small role 2" by batting order 1 (second operation), which is the correct operation mode, is determined by a winning type lottery, and an example was given in which, when the winning type "batting order strawberry" is won in the AT performance state, batting order 1, which is the correct operation mode, is announced as an auxiliary performance. However, this is not the only case. It is sufficient that the first selected winning type is determined by a winning type lottery in which a predetermined first role and a predetermined second role overlap, the first role can be won by the first operation, and the second role can be won by the second operation, and the second operation is notified when the first selected winning type is won in the AT performance state. Also, in this case, the relationship of the payout amount when winning is only required to be first role < second role.

In the above-mentioned embodiment, as explained using FIG. 34, the winning roles "small role 33" and "small role 34" (both third roles) with a payout of 1 coin overlap with the winning role "small role 1" (fourth role) with a payout of 15 coins, and either or both of the winning roles "small role 33" and "small role 34" can be won by pressing left (third operation), and the winning type "batting order chance role B" (second selected winning type) set to be able to win the winning role "small role 1" by pressing center, pressing right, or pressing 4th (all fourth operations) is determined by lottery, and an example was given in which a left press is notified as an auxiliary performance when the winning type "batting order chance role B" is won in a non-AT performance state. However, this is not the only case. It is sufficient that the second selected winning type, in which the third role and the fourth role overlap, the third role can be won by the third operation, and the fourth role can be won by the fourth operation, is determined by a winning type lottery, and the third operation is notified when the second selected winning type is won in a non-AT performance state. In addition, the relationship of the payout amount when winning is only required to be the third role < the fourth role.

In this way, one of multiple types of winning types is determined by lottery for the winning type, including a first selected winning type in which the first role and the second role overlap, the first role can be won by the first operation, and the second role can be won by the second operation, and a second selected winning type in which the third role and the fourth role overlap, the third role can be won by the third operation, and the fourth role can be won by the fourth operation. On the assumption that the second operation may be notified when the first selected winning type is won in the AT presentation state, and the third operation may be notified when the second selected winning type is won in the non-AT presentation state, the relationship of the number of payouts when a winning type is won may be the second role > the third role, and the total number of times multiple third roles are won simultaneously > the first role. This configuration allows the expected number of coins to be won per unit of play in a non-AT presentation state to be relatively low compared to the expected number of coins to be won per unit of play in an AT presentation state, making it possible to increase the difference in the expected number of coins to be won between the non-AT presentation state and the AT presentation state while maintaining the player's motivation to play.

As explained using FIG. 35, when the winning type "batting order chance role A" (second selection winning type) is won in a non-AT performance state, the winning role "small role 35" (third role) and the winning role "small role 36" (third role) are simultaneously won in response to the notification of the left push (third operation) and the number of payouts is a specified number (3 coins). However, this is not limited to such a case, and when the winning type of the second selection winning type is won in a non-AT performance state, the number of payouts when multiple third roles are simultaneously won in response to the notification of the third operation is sufficient as long as it is equal to or more than the specified number, and for example, the total number of multiple third roles may be set to any number between 4 and 14 coins. In this way, by setting the total number of payouts to 3 coins or more, the suppression of the effect of increasing the difference in the expected number of coins between the non-AT performance state and the AT performance state is minimized, and the player's motivation to play is improved, and the player can start the next game without performing the troublesome task of betting additional medals.

In the above embodiment, examples have been given in which two winning roles, "small role 33" (third role) and "small role 34" (third role), which overlap in the winning type "batting order chance role B" (second selected winning type), and two winning roles, "small role 35" (third role) and "small role 36" (third role), which overlap in the winning type "batting order chance role A" (second selected winning type), can win simultaneously. However, the number of winning roles that can win simultaneously is not limited to two, and it is sufficient that three or more winning roles can be set to win at once, such as three winning roles with a payout of one coin.

In the above-mentioned embodiment, examples were given in which two winning roles, "small role 33" (third role) and "small role 34" (third role), which overlap in the winning type "batting order chance role B" (second selected winning type), and two winning roles, "small role 35" (third role) and "small role 36" (third role), which overlap in the winning type "batting order chance role A" (second selected winning type), can simultaneously win on one valid line A, but this is not the only case, and multiple winning roles may each win on different valid lines at the same time.

In addition, in the above embodiment, an example was given in which the number of reels 110 is four (left reel 110a, center reel 110b, right reel 110c, fourth reel 110d), but this is not limited to this case, and the invention can also be applied to cases in which the number of reels 110 is three (left reel 110a, center reel 110b, right reel 110c) or five or more.

Figure 38 is an explanatory diagram for explaining the winning mode of the winning type "batting order chance role C". Here, the reels 110 are composed of the three reels 110a, 110b, and 110c in Figure 3(a), and the activated line A is set to a line connecting the positions corresponding to the symbols stopped in the middle of the left reel 110a, the middle of the middle reel 110b, and the middle of the right reel 110c among the nine symbols (three reels x three rows, top, middle, and bottom) facing the symbol display window 108. Also, here, the winning type "batting order chance role C" is set provisionally. As shown in the upper part of FIG. 38, the winning type "batting order chance role C" is a selected winning type that includes the winning role "small role 4" (third role) with a payout of 1 coin, the winning role "small role 5" (third role) with a payout of 2 coins, and the winning role "small role 3" (fourth role) with a payout of 15 coins. In addition, when the winning type "batting order chance role C" is won, in the non-AT performance state, it is possible to win a winning role (correct role) with a small payout number by the correct operation mode, and in the AT performance state, it is possible to win a winning role (correct role) with a large payout number by the correct operation mode. Here, an example is described in which it is possible to win a winning role (correct role) with a small payout number by the non-AT performance state, that is, a winning role (correct role) with a small payout number by the correct operation mode.

As shown in FIG. 38, when the winning type "batting order chance role C" is won and the stop switch 120a is operated to stop the left reel 110a first according to the correct operation mode of pushing left, the symbols "red 7" or "bell" constituting the winning roles "small role 4" and "small role 5", which have the largest number of symbol combinations of winning roles that can be displayed on the activated line A, are set to be displayed preferentially among the symbols "replay", "red 7", and "bell" that are the targets of drawing. Then, the reel control means 306 performs stop control so that the symbols "red 7" or "bell" are displayed preferentially on the activated line A according to the operation of the stop switch 120a. Note that the arrangement of the symbols "red 7" and "bell" is PB=1 on the left reel 110a, so that one of the symbols can always be displayed on the activated line A by the stop control. In this way, when the symbol "red 7" or "bell" stops on the pay line A of the left reel 110a, the winning role "small role 3" included in the winning type "batting order chance role C" has no chance of winning, and only the winning roles "small role 4" and "small role 5" have the chance of winning. Then, when the stop switch 120b is operated to stop the center reel 110b second, the symbol "bell" constituting the winning role "small role 5" to be drawn in is set to be displayed preferentially. Then, the reel control means 306 performs stop control so that the symbol "bell" is displayed preferentially on the pay line A in response to the operation of the stop switch 120b. Note that the symbol "bell" can always be displayed on the pay line A by the stop control since PB=1 on the center reel 110b. Then, when the stop switch 120c is operated to stop the right reel 110c third, the symbol "bell" constituting the winning role "small role 4" to be drawn in is set to be displayed preferentially. Then, in response to the operation of the stop switch 120c, the reel control means 306 performs stop control so that the "bell" symbol is preferentially displayed on the pay line A. Note that since the "bell" symbol has PB=1 on the right reel 110c, the stop control ensures that the symbol is displayed on the pay line A. In this way, by the "bell" symbol stopping on the pay line A of the right reel 110c, both the winning combination of "minor combination 4" and the winning combination of "minor combination 5" are confirmed, and the player can receive a payout of three medals (one medal + two medals).

Next, as shown in FIG. 38, when the winning type "batting order chance role C" is won and the stop switch 120b is operated to stop the center reel 110b first according to the incorrect operation mode of the center push, the pattern "cherry" constituting the winning role "small role 3" which has the largest number of medals paid out, 15, is set to be displayed preferentially among the patterns "cherry" and "bell" to be drawn. Then, the reel control means 306 performs stop control so that the pattern "cherry" is displayed preferentially on the effective line A in response to the operation of the stop switch 120b. Note that the pattern "cherry" can always be displayed on the effective line A by the stop control, since PB=1 on the middle reel 110b. In this way, by the pattern "cherry" stopping on the effective line A of the middle reel 110b, the winning role "small role 5" included in the winning type "batting order chance role C" has no possibility of winning, and only the winning roles "small role 3" and "small role 4" have the possibility of winning. Next, when the stop switch 120a is operated to stop the left reel 110a second, the symbol "REPLAY" constituting the winning combination "small combination 3" which has the largest number of medals paid out, 15, is set to be displayed preferentially among the symbols "REPLAY", "RED 7", and "BELL" to be drawn. Then, the reel control means 306 performs stop control so that the symbol "REPLAY" is displayed preferentially on the pay line A in response to the operation of the stop switch 120a. Note that the symbol "REPLAY" can always be displayed on the pay line A by the stop control since PB=1 on the left reel 110a. In this way, by stopping the symbol "REPLAY" on the pay line A of the left reel 110a, the winning combination "small combination 4" included in the winning type "batting order chance combination C" has no chance of winning, and only the winning combination "small combination 3" has the chance of winning. Next, when the stop switch 120c is operated to stop the right reel 110c third, the reel is set so that the "REPLAY" symbol, which is the target of the draw, is preferentially displayed. Then, the reel control means 306 performs stop control so that the "REPLAY" symbol is preferentially displayed on the pay line A in response to the operation of the stop switch 120c. Note that since the "REPLAY" symbol has a PB of 1 on the right reel 110c, the stop control ensures that the "REPLAY" symbol is displayed on the pay line A. In this way, the "REPLAY" symbol stops on the pay line A of the right reel 110c, confirming the winning combination "MINOR WIN 3", and the player can receive a payout of 15 medals.

Here, when the winning type "Batting Order Chance Role C" is won in a non-AT performance state, if the player performs the correct operation mode according to the auxiliary performance, the winning role "Small Role 4" with a payout of one coin and the winning role "Small Role 5" with a payout of two coins will both be won, and a total of three medals will be paid out. In this way, by setting the total payout number to three coins, the suppression of the effect of increasing the difference in the expected number of coins won between the non-AT performance state and the AT performance state is minimized, and the player's motivation to play is increased, while the player can start the next game without having to go through the trouble of betting additional medals.

In the above-described embodiment, the transition of the presentation state was described using FIG. 9. However, the specifications of the winning type "Strawberry Batting Order" and the winning type "Chance Batting Order" described above are not limited to the example in FIG. 9, and can be applied to various transitions of the presentation state. Other examples of transitions of the presentation state are described below.

Figures 39 to 44 are explanatory diagrams for explaining the transition of the presentation state. Here, the presentation state transitioned by the presentation state control means 314 in the main control board 200 will be described in detail. Note that here, the game state is assumed to be the game state inside the RBB. In each figure, "Strawberry Navi" indicates whether or not to notify the operation mode capable of winning a winning role with a payout of 15 coins when the winning type "Strawberry in Batting Order" is won, "Yes" indicates that it will be notified, "No" indicates that it will not be notified, and "Low" indicates that it will be notified but the probability of notifying is low. Also, "Low Payout Navi" indicates whether or not to notify the operation mode capable of winning a winning role with a payout of less than 15 coins when the winning type "Strawberry in Batting Order" is won, "Yes" indicates that it will be notified, and "No" indicates that it will not be notified.

In the example of FIG. 39, the game first stays in the normal presentation state as the initial state. In the normal presentation state, there is no strawberry navigation and there is a low payout navigation. When a predetermined transition condition is met during the normal presentation state, the presentation state control means 314 transitions to a favorable zone and transitions the presentation state to an AT preparation presentation state (1). In the AT preparation presentation state, the strawberry navigation can be set to any value ("Yes", "No", or "Low"), and the low payout navigation can be set to any value ("Yes" or "No"). When a predetermined transition condition is met during the AT preparation presentation state, the presentation state control means 314 transitions the presentation state to an AT presentation state (2). In the AT presentation state, there is a strawberry navigation and there is no low payout navigation, so the player can win many medals while suppressing medal consumption. When the AT presentation state ends, the presentation state control means 314 transitions the presentation state to an interval presentation state (3). In the interval presentation state, the strawberry navigation can be set to any value ('none' or 'low'), and the low payout navigation can be set to any value ('yes' or 'no'). If the presentation state control means 314 meets a predetermined transition condition before the interval presentation state ends, it returns to the AT presentation state (4). In addition, the presentation state control means 314 transitions the presentation state to the ending presentation state based on the value counted in the advantageous zone reaching a predetermined value (for example, the number of stays reaches a predetermined number of plays that is less than 1500, or the net increase in number exceeds a predetermined number that is less than 2400) (5). In the ending presentation state, there is a strawberry navigation and there is no low payout navigation, so the player can win many medals while suppressing medal consumption. In addition, the presentation state control means 314 transitions the presentation state to the normal presentation state when a predetermined end condition is met in the interval presentation state or the ending presentation state ends (6).

In the example of FIG. 40, the game first stays in the normal presentation state as the initial state. In the normal presentation state, there is no strawberry navigation and there is a low payout navigation. When a predetermined transition condition is met during the normal presentation state, the presentation state control means 314 transitions to the advantageous zone and transitions the presentation state to the CZAT preparation presentation state (1). In the CZAT preparation presentation state, the strawberry navigation can be set to any value ("Yes", "No", or "Low"), and the low payout navigation can be set to any value ("Yes" or "No"). When a predetermined transition condition is met during the CZAT preparation presentation state, the presentation state control means 314 transitions the presentation state to the CZAT presentation state (2). In the CZAT presentation state, there is a strawberry navigation and there is no low payout navigation, so the player can win many medals while suppressing medal consumption. When the CZAT presentation state ends, the presentation state control means 314 transitions the presentation state to the CZ presentation state (3). In the CZ presentation state, the strawberry navigation can be set to any value ("Yes", "No", or "Low"), and the low payout navigation can be set to any value ("Yes" or "No"). The presentation state control means 314 transitions the presentation state to the AT presentation state when a predetermined transition condition is met before the CZ presentation state ends (4). The presentation state control means 314 may also transition the presentation state to the AT presentation state when a predetermined transition condition is met during the CZAT presentation state (5). In the AT presentation state, there is a strawberry navigation and there is no low payout navigation, so the player can win many medals while suppressing medal consumption. When the AT presentation state ends, the presentation state control means 314 transitions the presentation state to the interval presentation state (6). In the interval presentation state, the strawberry navigation can be set to any value ("Yes", "No", or "Low"), and the low payout navigation can be set to any value ("Yes" or "No"). When a predetermined transition condition is met before the interval presentation state ends, the presentation state control means 314 returns to the AT presentation state (7). Furthermore, when the value counted in the advantageous zone reaches a predetermined value, the presentation state control means 314 transitions the presentation state to an ending presentation state (8). In the ending presentation state, there is a strawberry navigation and there is no low-payout navigation, so the player can win many medals while minimizing medal consumption. Furthermore, when a predetermined end condition is met in the CZ presentation state or the interval presentation state, or when the ending presentation state ends, the presentation state control means 314 transitions the presentation state to a normal presentation state (9).

In the example of FIG. 41, the normal presentation state is the initial state. In the normal presentation state, there is no strawberry navigation and there is a low payout navigation. When a predetermined transition condition is met during the normal presentation state, the presentation state control means 314 transitions to a favorable zone and transitions the presentation state to a CZAT preparation presentation state (1). In the CZAT preparation presentation state, the strawberry navigation can be set to any value ("none" or "low"), and the low payout navigation can be set to any value ("yes" or "no"). When the CZAT preparation presentation state ends, the presentation state control means 314 returns to the normal presentation state (2). Note that the presentation state may be transitioned to an interval presentation state without immediately returning to the normal presentation state after the end of the CZAT preparation presentation state. When an interval presentation state is provided, in the interval presentation state, the strawberry navigation can be set to any value ("yes", "no" or "low"), and the low payout navigation can be set to any value ("yes" or "no"). When a predetermined transition condition is satisfied during the CZAT preparation presentation state, the presentation state control means 314 transitions the presentation state to the CZAT presentation state (3). In the CZAT presentation state, there is a strawberry navigation and there is no low-dividend navigation, so the player can win many medals while suppressing medal consumption. When a predetermined transition condition is satisfied during the CZAT presentation state, the presentation state control means 314 transitions the presentation state to the AT preparation presentation state (4). In the AT preparation presentation state, there is a strawberry navigation and there is no low-dividend navigation, so the player can win many medals while suppressing medal consumption. It is also possible to specify a presentation state that does not include an AT preparation presentation state, and in that case, when a predetermined transition condition is satisfied during the CZAT presentation state, the presentation state control means 314 transitions the presentation state directly to the AT presentation state. When a predetermined transition condition is satisfied during the AT preparation presentation state, the presentation state control means 314 transitions the presentation state to the AT presentation state (5). In the AT presentation state, there is a strawberry navigation and there is no low-dividend navigation, so the player can win many medals while minimizing medal consumption. In addition, the presentation state control means 314 transitions the presentation state to an ending presentation state based on the value counted in the advantageous zone reaching a predetermined value (6). In the ending presentation state, there is a strawberry navigation and there is no low-dividend navigation, so the player can win many medals while minimizing medal consumption. In addition, when a predetermined end condition is met in the CZAT presentation state or the AT presentation state, or when the ending presentation state ends, the presentation state control means 314 transitions the presentation state to a normal presentation state (7).

In the example of FIG. 42, the game first stays in the normal presentation state as the initial state. In the normal presentation state, there is no strawberry navigation and there is a low payout navigation. When a predetermined transition condition is met during the normal presentation state, the presentation state control means 314 transitions to a favorable zone and transitions the presentation state to a CZAT preparation presentation state (1). In the CZAT preparation presentation state, the strawberry navigation can be set to any value ("none" or "low"), and the low payout navigation can be set to any value ("yes" or "no"). When a predetermined transition condition is met during the CZAT preparation presentation state, the presentation state control means 314 transitions the presentation state to a CZAT presentation state (2). In the CZAT presentation state, there is a strawberry navigation, and the low payout navigation can be set to any value ("yes" or "no"). Therefore, the player can win many medals while suppressing medal consumption. When a predetermined transition condition is met before the CZAT presentation state ends, the presentation state control means 314 transitions the presentation state to an AT presentation state (3). In the AT presentation state, since there is a strawberry navigation and there is no low-dividend navigation, the player can acquire many medals while suppressing the consumption of medals. When the AT presentation state ends, the presentation state control means 314 shifts the presentation state to a continuation judgment presentation state (4). In the continuation judgment presentation state, the strawberry navigation can be set arbitrarily ("Yes", "No" or "Low"), and the low-dividend navigation can be set arbitrarily ("Yes" or "No"). If a predetermined transition condition is satisfied before the continuation judgment presentation state ends, the presentation state control means 314 returns to the AT presentation state (5). In addition, the presentation state control means 314 shifts the presentation state to an ending presentation state based on the value counted in the advantageous zone reaching a predetermined value (6). In the ending presentation state, there is a strawberry navigation and there is no low-dividend navigation, so the player can acquire many medals while suppressing the consumption of medals. In addition, when a predetermined end condition is met in the CZAT presentation state or the continuation judgment presentation state, or when the ending presentation state ends, the presentation state control means 314 transitions the presentation state to the normal presentation state (7).

In the example of FIG. 43, the game first stays in the normal presentation state as the initial state. In the normal presentation state, there is no strawberry navi but there is a low payout navi. When a predetermined transition condition is met during the normal presentation state, the presentation state control means 314 transitions to a favorable zone and transitions the presentation state to a pseudo-bonus preparation presentation state (1). In the pseudo-bonus preparation presentation state, the strawberry navi can be set to any value ("Yes", "No", or "Low"), and the low payout navi can be set to any value ("Yes" or "No"). When a predetermined transition condition is met during the pseudo-bonus preparation presentation state, the presentation state control means 314 transitions the presentation state to a pseudo-bonus presentation state (2). The pseudo (pseudo) bonus presentation state is a presentation state that simulates a bonus game state, and the start of the presentation state is indicated by, for example, displaying a symbol such as "red 7" reminiscent of a bonus role in a straight line in the symbol display window 108. In the pseudo bonus presentation state, since there is a strawberry navigation and there is no low payout navigation, the player can win many medals while suppressing the consumption of medals. When a predetermined transition condition is satisfied before the pseudo bonus presentation state ends, the presentation state control means 314 transitions the presentation state to an AT preparation presentation state (3). On the other hand, when the pseudo bonus presentation state ends without satisfying the predetermined transition condition, the presentation state control means 314 transitions the presentation state to a normal presentation state (4). Note that, when a predetermined transition condition is satisfied during the pseudo bonus preparation presentation state, the presentation state control means 314 may transition the presentation state to an AT preparation presentation state (5). In the AT preparation presentation state, the strawberry navigation can be set arbitrarily ("Yes", "No" or "Low"), and the low payout navigation can be set arbitrarily ("Yes" or "No"). When a predetermined transition condition is satisfied during the AT preparation presentation state, the presentation state control means 314 transitions the presentation state to an AT presentation state (6). As the AT performance state, for example, a plurality of AT modes with different average expected winning numbers per unit play (1, 2, 4, 6) are provided, and the performance state control means 314 determines one AT mode from the plurality of AT modes. When the AT performance state continues, the AT mode can be changed in a predetermined set unit, and once an AT mode is determined, an AT mode with a lower average expected winning number per unit play than that AT mode can be selected during the subsequent AT performance state. In the AT performance state, there is a strawberry navigation, and depending on the AT mode, for example, when the average expected winning number per unit play is 1 or 2, the low payout navigation can be set arbitrarily ("Yes" or "No"), and when the average expected winning number per unit play is 4 or 6, the low payout navigation can be set arbitrarily ("Yes" or "No"). In the AT performance state, the player can win many medals while suppressing medal consumption. In addition, the presentation state control means 314 transitions the presentation state to a specialized zone presentation state if a predetermined transition condition is satisfied before the AT presentation state ends (7). In the specialized zone presentation state, there is a strawberry navigation and there is no low-dividend navigation, so the player can win many medals while suppressing medal consumption. In addition, in the specialized zone presentation state, the probability of so-called topping-off, which extends the continuation of the AT presentation state, being executed is higher than in the AT presentation state. When the specialized zone presentation state ends, the presentation state control means 314 returns to the AT presentation state (8). In addition, the presentation state control means 314 may transition the presentation state to a pseudo-boom preparation presentation state if a predetermined transition condition is satisfied before the AT presentation state ends (9). In addition, the presentation state control means 314 transitions the presentation state to a normal presentation state if a predetermined end condition is satisfied in the AT presentation state (10).

In the example of FIG. 44, the normal presentation state is the initial state. In the normal presentation state, there is no strawberry navigation and there is a low dividend navigation. When a predetermined transition condition is satisfied during the normal presentation state, the presentation state control means 314 transitions to a favorable zone and transitions the presentation state to a pseudo-bonus preparation presentation state (1). Also, when a predetermined transition condition is satisfied during the normal presentation state, the presentation state control means 314 may transition the presentation state to a specialized zone presentation state as a presentation state preceding the transition to the pseudo-bonus preparation presentation state (2). In the specialized zone presentation state, the strawberry navigation can be set to any value ("Yes", "No", or "Low"), and the low dividend navigation can be set to any value ("Yes" or "No"). Also, in the specialized zone presentation state, a so-called top-up is performed to extend the duration of the pseudo-bonus presentation state. When the specialized zone presentation state ends, the presentation state control means 314 transitions the presentation state to a pseudo-bonus preparation presentation state (3). In the pseudo bonus preparation performance state, the strawberry navigation can be set to any value ("Yes", "No", or "Low"), and the low payout navigation can be set to any value ("Yes" or "No"). When a predetermined transition condition is satisfied during the pseudo bonus preparation performance state, the performance state control means 314 transitions the performance state to the pseudo bonus performance state (4). As the pseudo bonus performance state, for example, multiple pseudo bonus modes with different average expected number of coins per unit play (1.8 coins, 5 coins) are provided, and the performance state control means 314 determines one pseudo bonus mode from the multiple pseudo bonus modes. Note that the pseudo bonus mode can be changed during the pseudo bonus performance state. In the pseudo bonus performance state, there is a strawberry navigation, and depending on the AT mode, for example, when the average number of expected winnings per unit play is 1.8, the low payout navigation can be set to any value ("Yes" or "No"), and when the average number of expected winnings per unit play is 5, the low payout navigation can be set to none, and the low payout navigation can be set to any value ("Yes" or "No"). In the pseudo bonus performance state, the player can win many medals while suppressing medal consumption. If a predetermined transition condition is satisfied before the pseudo bonus performance state ends, the performance state control means 314 transitions the performance state to the AT performance state (5). As the AT performance state, for example, a plurality of AT modes with different averages of expected winnings per unit play (1.8, 4.5) are provided, and the performance state control means 314 transitions between the plurality of AT modes in stages. The presentation state control means 314 may, for example, transition to an AT presentation state of an AT mode in which the average number of expected winnings per unit play is 1.8, and may transition to an AT presentation state of an AT mode in which the average number of expected winnings per unit play is 4.5 when a predetermined transition condition is satisfied. In addition, when a predetermined termination condition is satisfied during the AT presentation state of the AT mode in which the average number of expected winnings per unit play is 4.5, the presentation state control means 314 returns to an AT presentation state of an AT mode in which the average number of expected winnings per unit play is 1.8. In the AT presentation state, there is a strawberry navigation, and depending on the AT mode, for example, when the average number of expected winnings per unit play is 1.8, the low payout navigation can be set to any value ("Yes" or "No"), and when the average number of expected winnings per unit play is 4.5, the low payout navigation can be set to no value ("Yes" or "No"). In the AT presentation state, the player can win many medals while minimizing medal consumption. In addition, the presentation state control means 314 may transition the presentation state to a pseudo-bonus presentation state if a predetermined transition condition is met before the AT presentation state ends (6). In addition, the presentation state control means 314 transitions the presentation state to a normal presentation state if a predetermined termination condition is met in the pseudo-bonus presentation state or the AT presentation state (7).

In the above-described embodiment, an example was given in which the effect switch 122 is configured as an effect operation unit used for operations including effect setting, and is configured as a push switch and a jog dial switch. However, the configuration of the effect switch 122 is not limited to this. For example, the effect switch 122 may be configured as a cross key and a decision button.

Here, when the player operates the settlement switch 123 to settle credits, a sound (e.g., a sound announcing the completion of the payout) related to the payout of medals based on the operation of the settlement switch 123 is output. If the left or right button of the cross key (first performance operation unit) is operated while the sound related to the payout of medals based on the operation of the settlement switch 123 is being output, the performance control means 334 stops the output of the sound related to the payout of medals and displays a volume adjustment screen for adjusting the volume on the liquid crystal display unit 124. Also, if the decision button (first performance operation unit) is operated while the sound related to the payout of medals based on the operation of the settlement switch 123 is being output, the performance control means 334 stops the output of the sound related to the payout of medals and displays a menu screen for making various settings on the liquid crystal display unit 124. That is, when the first performance operation unit is operated while a sound related to the payout of medals based on the operation of the settlement switch 123 is being output, the performance control means 334 stops output of the sound related to the payout of medals and performs processing based on the operation of the first performance operation unit.

On the other hand, even if the up and down buttons on the cross key (second performance operation unit) are operated while a sound related to the payout of medals based on the operation of the settlement switch 123 is being output, the performance control means 334 does not execute processing based on the up and down buttons on the cross key. In other words, even if the second performance operation unit is operated while a sound related to the payout of medals based on the operation of the settlement switch 123 is being output, the performance control means 334 does not stop output of the sound related to the payout of medals and does not execute processing based on the operation of the second performance operation unit.

Note that, here, the left and right buttons on the cross key and the Enter button have been described as the first performance operation unit, and the up and down buttons on the cross key have been described as the second performance operation unit, but this is not limited to the above, and any of the left, right, up, down, and Enter buttons on the cross key may be set as the first performance operation unit, or any other button may be set as the second performance operation unit.

In the above-described embodiment, the main control board 200 and the sub-control board 202 are arranged to share the functional parts for progressing the game, but the functional parts of the main control board 200 may be arranged on the sub-control board 202, or the functional parts of the sub-control board 202 may be arranged on the main control board 200, or all the functional parts may be arranged together on a single control board.

In the above embodiment, the game is played using medals as the game value, but the game value may be electrical information (it may be so-called medalless). In this case, when a winning combination is achieved, the amount of value corresponding to the winning combination may be given to the player in the form of electrical information.

Furthermore, each process performed by the main control board 200 and the sub-control board 202 described above does not necessarily have to be performed in chronological order according to the order described in the flowchart, and may include parallel or subroutine processing.
