Description

The present invention relates to an amusement machine.

In slot machines, which are used as gaming machines, multiple game states and presentation states that vary in the degree of advantage (game profit) given to the player are provided during the game. For example, some slot machines are designed to transition from a normal game state to a bonus game state in which the player has a greater chance of winning medals by displaying a symbol combination that corresponds to a bonus role on an active line.

In such slot machines, it is desirable to make effective use of the limited memory storage area in order to enhance playability. For example, a technique is known that reduces the amount of data required when controlling the reel stop by associating the same slip count data with multiple symbol positions (for example, Patent Document 1).

JP 2006-239010 A

In slot machines , when a winning type including a winning combination (correct combination) with a large gaming profit is won, the operation mode of the stop switch that is the winning condition of the correct combination is notified, and the so-called AT (assist time) may be executed, in which the player can easily display the symbol combination corresponding to the correct combination on the pay line. Here, if the arrangement of the symbols on the reels becomes monotonous, it may reduce interest .

In view of the above problems, the present invention has an object to provide a gaming machine that can increase entertainment value .

In order to solve the above-mentioned problems, the gaming machine of the present invention includes a winning type selection means for selecting one of a plurality of winning types by lottery, the winning type being a winning type in which a correct combination and an incorrect combination overlap, and a specific winning type including a specific winning combination (e.g., winning combination "Replay 3"), and a specific winning type different from the selected winning type (e.g., winning types "Symbol Replay A1" to "Symbol Replay B6"), the specific winning type including a specific winning combination (e.g., winning combination "Replay 3"), and a specific operation being set as a winning condition for the specific winning combination; 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 in response to an operation of a stop switch corresponding to the rotating reel; and and a game state control means for transitioning to one of a plurality of game states including a bonus internal game state (e.g., an RBB internal game state) which is transitioned to based on winning a bonus role (e.g., a winning role "RBB") in a non-internal game state, and a bonus operation game state (e.g., an RBB operation game state) which is transitioned to based on winning the bonus role. In the case where the selected winning type (e.g., a winning type "batting order bell 1A") is won, when the first reel (e.g., the right reel 110c) is operated to be stopped first, the correct role (e.g., the winning role "minor role 1") cannot be won, but the incorrect role (e.g., the winning role "minor role 16") can be won, and the pattern (e.g., the pattern "replay A") constituting the incorrect role on the first reel can be displayed on the activated line by the stop control. In the third reel (e.g., the left reel 110a), a first symbol (e.g., the symbol "bell") which is a part of the symbols (e.g., the symbols "bell" and "cherry") which constitute the incorrect answer combination is arranged so as to be always displayed on the effective line by the stop control, and a second symbol (e.g., the symbol "cherry") which is different from the first symbol among the symbols which constitute the incorrect answer combination on the third reel is arranged so as to be sometimes not displayed on the effective line by the stop control, and in the third reel, the first symbol and the second symbol are arranged so as to be always displayed on the effective line by the stop control, and in the third reel, a second symbol (e.g., the symbol "cherry") which is different from the first symbol among the symbols which constitute the incorrect answer combination is arranged so as to be sometimes not displayed on the effective line by the stop control, and in the third reel, the first symbol and the second symbol are arranged so as to be always ... The reel control means is arranged so as to have a positional relationship of a specific symbol (e.g., a symbol "BAR2") in a predetermined area (e.g., an invalid line B1) when the specific winning type is determined, and an auxiliary performance suggesting that the specific symbol can be displayed in the predetermined area when the specific winning type is determined may be executed, and in the third reel, the specific symbol is different from the first symbol and the second symbol, and in the bonus operating game state, may win a winning type in which a plurality of types of correct roles (e.g., winning roles "minor role 1" to "minor role 6") overlap (e.g., winning type "minor role ALL"), and in the non-internal game state and the bonus internal game state, a losing role in which none of the winning roles is won will not be won.

According to the present invention, it is possible to improve interest .

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 three reels 110 (left reel 110a, center reel 110b, right reel 110c) 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 Figure 3(a), multiple types of patterns are arranged in each of 20 equal areas on the outer peripheral surfaces of the left reel 110a, center reel 110b, and right reel 110c, and the player can view a total of nine patterns, three consecutive patterns located on the top, middle, and bottom rows of the left reel 110a, center reel 110b, and right reel 110c, through the pattern display window 108.

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, 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 those electrically stored inside the slot machine 100 (hereinafter simply referred to as credits).

The start switch 118 is, for example, a lever that can detect tilting operations, and detects the start operation of the game by the player. The stop switches 120 (stop switch 120a, stop switch 120b, stop switch 120c) are provided corresponding to the left reel 110a, the center reel 110b, and the right reel 110c, respectively, and detect the stop operation by the player. Note that when the stop switch 120 can be stopped, the first stop is when the player operates one of the stop switches 120a, 120b, and 120c to stop the reels, and after the first stop, the second stop is when the player operates one of the two stop switches 120 that have not been stopped, and after the second stop, the third stop is when the player operates the last remaining stop switch 120 to stop the reels. The effect switch 122 is, for example, a push switch and a jog dial switch arranged around it so that it can rotate freely, and detects the push operation and rotation operation by the player.

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 provide 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 front lower 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 degree of advantage in the game as a whole (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 allowing 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 any of the following: inserting medals credited through the operation of the bet switch 116, inserting medals through the medal insertion section 114, and automatically inserting medals 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 line. As shown in FIG. 3(b), the active line A is set to a line connecting the positions corresponding to the symbols stopped in the middle row of the left reel 110a, the middle row of the middle reel 110b, and the top row of the right reel 110c among the nine symbols (three reels x three rows: top, middle, and bottom) facing the symbol display window 108. Invalid lines are lines other than the valid line A that are not used to determine whether a winning combination has been won, and which display other symbol combinations that make it easier to determine the winning combination when it is difficult to determine the winning combination based on the symbol combination displayed on the valid line A alone. In this embodiment, the five invalid lines B1, B2, B3, C1, and C2 shown in FIG. 3(b) are assumed.

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

In this embodiment, the above-mentioned one game refers to the 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, and right reel 110c 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, and right reel 110c corresponding to the operated stop switch 120a, 120b, 120c are controlled to stop in response to the result of the winning type lottery and the player's operation of the multiple stop switches 120a, 120b, and 120c, and if 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 a prize, one game ends when the left reel 110a, center reel 110b, and right reel 110c 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.

(Electrical Configuration of Slot Machine 100)
Fig. 4 is a block diagram showing a schematic electrical configuration of the slot machine 100. As shown in Fig. 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 only one direction 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 medal insertion detection unit 114b, 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, and 120c, 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 achieved, and more specifically, whether or not a winning type that includes a winning role has been achieved.

The reel control means 306 controls the rotation of the left reel 110a, middle reel 110b, and right reel 110c in response to the operation of the start switch 118, and controls the stopping of the corresponding left reel 110a, middle reel 110b, and right reel 110c in response to the operation of the stop switches 120a, 120b, and 120c corresponding to the rotating left reel 110a, middle reel 110b, and right reel 110c, respectively. In addition, the reel control means 306 may extend the time from enabling the operation of the stop switches 120a, 120b, 120c in the previous game to enabling the operation of the stop switches 120a, 120b, 120c 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 in the previous game) to a specified time in response to the operation of the start switch 118, and during that time, perform a reel effect (freeze effect) in which the reels 110a, 110b, 110c 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 the rotation start signal for the left reel 110a, center reel 110b, and right reel 110c sent from the reel control means 306 in response to the operation signal of the start switch 118. The reel drive control unit 150 also stops the driving of the stepping motor 152 based on the stop signal for each of the left reel 110a, center reel 110b, and right reel 110c and the detection signal of the rotation position detection circuit 154 sent from the reel control means 306 in response to the operation signal of 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 lottery for determining the winning type and the result of the judgment by the judgment means 308, and transitions the game state to one of a plurality of game states. The presentation state control means 314 refers to the result of the lottery for determining the winning type, the result of the judgment by the judgment means 308, and transition information of the game state, and transitions the presentation state to one of a plurality of 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 (random number generating means) 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 performance, 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 (random number generating means) 202d, and the random numbers generated by the random number generator 202d (hereinafter referred to as performance lottery 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, and 120c, 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 the winning combination, and FIG. 6 and FIG. 7 are explanatory diagrams for explaining 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 and the like 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 placing 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 roles in this embodiment include replay roles "Replay 1" to "Replay 7". In addition, small roles include "Small Role 1" to "Small Role 39". In addition, a bonus role includes a winning role "RBB". In FIG. 5, one or more symbols constituting each winning role are associated with the left reel 110a, center reel 110b, and right reel 110c.

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. 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 prizes 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" to "Replay 4", "Small Role 1" to "Small Role 6", and "Small Role 35" to "Small Role 39" are arranged on each reel 110 so that they can always be displayed on the pay line A by the above-mentioned stop 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 5" to "Replay 7", "Small Role 7" to "Small Role 34", 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 stop control, so so-called missed wins may occur. Such a winning role may be expressed as PB≠1.

As shown in Figures 6 and 7, the winning type lottery table is divided into multiple winning areas, and the winning types that are the subject of the lottery vary depending on each game state, and the presence or absence of non-wins (misses) varies. In Figures 6 and 7, the winning areas (winning types) assigned to each game state (non-internal game state (not internal), game state while inside RBB (while inside RBB), game state while RBB is operating (RBB operating)) are represented by "◎" or "○", but in reality, a winning type lottery table corresponding to each of the multiple game states is stored in the main ROM 200b. Note that "◎" indicates a winning type that allows the lottery to transfer to an advantageous zone and allows the lottery to be held, and "○" indicates a winning type that does not allow the lottery to transfer to an advantageous zone and does not allow the lottery to be held.

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" for 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, the winning type "Miss" is associated with winning area 0, and when this winning type is won, the symbol combination corresponding to any of the winning roles shown in FIG. 5 will not be displayed on the active line A, and no medals will be paid out. However, as described below, if the RBB internal winning flag is carried over to the next game, winning the winning type "Miss" makes it possible to display the symbol combination corresponding to the winning role "RBB" on the active line A.

In addition, winning area 1 is associated with a winning type "small win ALL" which includes overlapping winning roles "small win 1" to "small win 39", winning area 2 is associated with a winning type "1 coin ALL A" which includes overlapping winning roles "small win 11" to "small win 39", and winning area 3 is associated with a winning type "1 coin ALL B" which includes overlapping winning roles "small win 12" to "small win 27". In addition, winning area 4 is associated with the winning type "1 choice 1" which includes the overlapping winning roles "small role 12" and "small role 20", winning area 5 is associated with the winning type "1 choice 2" which includes the overlapping winning roles "small role 13" and "small role 21", winning area 6 is associated with the winning type "1 choice 3" which includes the overlapping winning roles "small role 14" and "small role 22", and winning area 7 is associated with the winning type "1 choice 4" which includes the overlapping winning roles "small role 15" and "small role 23". In addition, the winning area 8 is associated with a winning type "weak cherry" which includes the winning roles "small role 35" and "small role 36" in overlapping relation, the winning area 9 is associated with a winning type "strong cherry" which includes the winning roles "small role 37" to "small role 39" in overlapping relation, the winning area 10 is associated with a winning type "watermelon A" which includes the winning roles "small role 7", "small role 8", and "small role 11" in overlapping relation, the winning area 11 is associated with a winning type "watermelon B" which includes the winning roles "small role 7" to "small role 10" in overlapping relation, and the winning area 12 is associated with a winning type "strong bell" which includes the winning roles "small role 1", "small role 3", and "small role 5" in overlapping relation. In addition, winning area 13 is associated with a winning type "common bell A" that includes the winning roles "small role 1" to "small role 6" in overlapping fashion, and winning area 14 is associated with a winning type "common bell B" that includes the winning roles "small role 1" to "small role 6" and "small role 11" in overlapping fashion.

In addition, winning regions 15 to 26 are associated with selected winning types (winning types "Batting Order Bell 1A" to "Batting Order Bell 6A" and "Batting Order Bell 1B" to "Batting Order Bell 6B") that overlap correct roles with a payout of 11 coins (winning roles "Small Role 1" to "Small Role 6") and incorrect roles with a payout of 1 coin (winning roles "Small Role 12" to "Small Role 34").

According to the winning type selection table in FIG. 7, winning areas 27-39 are associated with winning types "Symbol Replay A1"-"Symbol Replay A7" and "Symbol Replay B1"-"Symbol Replay B6", which include overlapping winning roles "Replay 1"-"Replay 7". According to winning area 40, the winning type "Normal Replay", which includes overlapping winning roles "Replay 1" and "Replay 2", is associated.

In addition, winning regions 41 to 46 are associated with winning types "RBB1" to "RBB6" that include the winning combination "RBB" alone or in combination with other minor combinations.

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

In the following description, the operation of the stop switches 120a, 120b, and 120c that stop the reels in the order of left reel 110a, center reel 110b, and right reel 110c is referred to as "batting order 1," the operation of the stop switches 120a, 120b, and 120c that stop the reels in the order of left reel 110a, right reel 110c, and center reel 110b is referred to as "batting order 2," and the operation of the stop switches 120a, 120b, and 120c that stop the reels in the order of center reel 110b, left reel 110a, and right reel 110c is referred to as "batting order 3." ", the operation of the stop switches 120a, 120b, 120c that stop the reels in the order of center reel 110b, right reel 110c, and left reel 110a is "batting order 4", the operation of the stop switches 120a, 120b, 120c that stop the reels in the order of right reel 110c, left reel 110a, and center reel 110b is "batting order 5", and the operation of the stop switches 120a, 120b, 120c that stop the reels in the order of right reel 110c, center reel 110b, and left reel 110a is "batting order 6".

For example, in a non-internal game state, when the winning type "batting order bell 1A" in the winning area 15 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 1", which is a correct role with a payout of 11 coins, is preferentially displayed on the valid line A. Also, when an operation is performed according to batting order 2, the stop control is performed so that the symbol combination corresponding to the winning role "small role 28", which is an incorrect role with a payout of 1 coin, is preferentially displayed on the valid line A. When an operation is performed according to batting orders 3 and 4, the stop control is performed so that the symbol combination corresponding to the winning role "small role 12", which is an incorrect role with a payout of 1 coin, is preferentially displayed on the valid line A with a probability of 1/4. When an operation is performed according to batting orders 5 and 6, the stop control is performed so that the symbol combination corresponding to the winning role "small role 16", which is an incorrect role with a payout of 1 coin, is preferentially displayed on the valid line A with a probability of 1/4.

The probability of winning (number of pieces placed) for each winning type in the winning areas 15 to 26 is set to be equal. Since players usually cannot know which winning type they have won, the provision of the winning areas 15 to 26 as described above makes it difficult for correct combinations to win. Also, as described above, even if the stop switches 120a, 120b, and 120c are operated in a hitting order that prioritizes the display of incorrect combinations, it is not necessarily possible to display the symbol combination corresponding to the incorrect combination on the pay line A, so that a miss may occur depending on the manner of operation (PB ≠ 1).

Figure 8 is an explanatory diagram for explaining the stop control of the reels 110a, 110b, and 110c when the operation is performed by the batting order 3 or 4 in the case where the winning types "symbol replay A1" to "symbol replay A7" are won. When any of the winning types "symbol replay A1" to "symbol replay A7" including the winning role "Replay 3" (specific role) in the winning areas 27 to 33 is won and the operation is performed by the batting order 3 or 4, the stop control is performed so that the symbol combination corresponding to the winning role "Replay 3" is displayed on the pay line A. At this time, the stop control is different for one condition device (winning role "Replay 3"). In other words, the stop control of the winning role "Replay 3" is performed so that the symbol displayed preferentially on the pay line A is different (so that the display mode is different) depending on which of the winning types "symbol replay A1" to "symbol replay A7" is won.

Specifically, when the winning type "Symbol Replay A1" is determined, as shown in FIG. 8(a), the reels are stopped so that the symbol "BAR2" is preferentially displayed on the activated line A on the left reel 110a, the symbol "Replay A" on the center reel 110b, and the symbol "Cherry" on the right reel 110c. As a result, on the inactive line B1, the symbol "BAR2" can only be displayed on the left reel 110a, and the symbol "BAR2" is not displayed on the center reel 110b or right reel 110c.

In addition, when the winning type "Symbol Replay A2" is determined, as shown in FIG. 8(b), the reels are stopped so that the "Bell" symbol is preferentially displayed on the activated line A on the left reel 110a, the "BAR2" symbol is preferentially displayed on the center reel 110b, and the "Cherry" symbol is preferentially displayed on the right reel 110c. As a result, on the inactive line B1, the "BAR2" symbol can only be displayed on the center reel 110b, and the "BAR2" symbol is not displayed on the left reel 110a or the right reel 110c.

In addition, when the winning type "Symbol Replay A3" is determined, as shown in FIG. 8(c), the stop control is performed so that the symbol "BAR2" is preferentially displayed on the activated line A on the left reel 110a, the symbol "BAR2" on the center reel 110b, and the symbol "Cherry" on the right reel 110c. As a result, the symbol "BAR2" can only be displayed on the inactive line B1 on the left reel 110a and center reel 110b, and the symbol "BAR2" is not displayed on the right reel 110c.

In addition, when the winning type "Symbol Replay A4" is determined, as shown in FIG. 8(d), the reels are stopped so that the "Bell" symbol is preferentially displayed on the activated line A on the left reel 110a, the "Replay A" symbol is preferentially displayed on the center reel 110b, and the "Watermelon" symbol is preferentially displayed on the right reel 110c. As a result, on the inactive line B1, the "BAR2" symbol can only be displayed on the right reel 110c, and the "BAR2" symbol is not displayed on the left reel 110a or center reel 110b.

In addition, when the winning type "Symbol Replay A5" is determined, as shown in FIG. 8(e), the reels are stopped so that the "BAR2" symbol is preferentially displayed on the activated line A on the left reel 110a, the "Replay A" symbol is preferentially displayed on the center reel 110b, and the "Watermelon" symbol is preferentially displayed on the right reel 110c. As a result, the "BAR2" symbol can only be displayed on the left reel 110a and right reel 110c on the inactive line B1, and the "BAR2" symbol is not displayed on the center reel 110b.

In addition, when the winning type "Symbol Replay A6" is determined, as shown in FIG. 8(f), the reels are stopped so that the "bell" symbol is preferentially displayed on the activated line A on the left reel 110a, the "BAR2" symbol is preferentially displayed on the center reel 110b, and the "watermelon" symbol is preferentially displayed on the right reel 110c. As a result, the "BAR2" symbol can only be displayed on the center reel 110b and right reel 110c on the inactive line B1, and the "BAR2" symbol is not displayed on the left reel 110a.

In addition, when the winning type "Symbol Replay A7" is determined, as shown in FIG. 8(g), the stop control is performed so that the symbol "BAR2" is preferentially displayed on the activated line A on the left reel 110a, the symbol "BAR2" on the middle reel 110b, and the symbol "watermelon" on the right reel 110c. As a result, the symbol "BAR2" can be displayed on the inactive line B1 on the left reel 110a, middle reel 110b, and right reel 110c.

In addition, the stop control of reels 110a, 110b, and 110c when operations are performed in hitting orders 3 and 4 when the winning types "Symbol Replay B1" to "Symbol Replay B6" in winning areas 34 to 39 are won is the same as the stop control of reels 110a, 110b, and 110c when operations are performed in hitting orders 3 and 4 when the winning types "Symbol Replay A1" to "Symbol Replay A6" in winning areas 27 to 32 are won.

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 set, 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. 9. 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 1/30).

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 the winning area 1, and "1-piece ALLA" and "1-piece ALLB" in the winning areas 2 and 3. When the "small role ALL" winning type is won, a symbol combination corresponding to one of the winning roles "small role 1" to "small role 39" 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 one of the winning roles "small role 11" to "small role 39" 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 RBB-operated gaming state are met, i.e., when the number of coins won reaches a predetermined number, the gaming state control means 312 transitions the gaming state to a non-internal gaming 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 (special 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 probability of winning a winning role related to winning is higher than in the RBB internal game state.

(Transition of performance state)
10 is an explanatory diagram for explaining the transition of the presentation state. Below, the presentation state (non-AT presentation state, AT presentation state) transitioned by the presentation state control means 314 in the main control board 200 will be described in detail. In addition, the following will explain the case where the game state is the game state inside the RBB.

Here, in order to comprehensively and uniformly determine whether or not the game state with high medal acquisition performance is biased, a game area that has a performance related to the instruction function, that is, a game area that is advantageous to the player, including a game area that executes an auxiliary performance (instruction function), is defined as an advantageous area (specific area). Note that the advantageous area is a game area in which instruction information may be sent to a peripheral board such as the sub-control board 202 only when the instruction content is displayed on the main notification means, for example, so that the main control board 200 can identify the instruction content when the 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. In addition, a game area different from the advantageous area is defined as a non-advantageous area. Therefore, multiple performance states (non-AT performance state, AT performance state) belong to either the advantageous area or the non-advantageous area, which are game areas. In this embodiment, almost all performance states belong to the advantageous area, and a non-advantageous area is realized in some performance states of the non-AT performance state (here, the non-advantageous 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, 11 coins), when an auxiliary effect that assists in winning the correct combination (an auxiliary effect that can obtain the maximum payout number) 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 (number of games played) reaches 1,500 games, or the number of coins won (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 execution of the auxiliary performance is extremely low compared to the AT performance state, and the auxiliary performance is almost not performed, so the number of medals that can be acquired is limited. Here, six performance states are provided as the non-AT performance state, such as a normal performance state, a non-advantageous performance state, a preparation performance state, a first interval performance state, a continuous lottery performance state, and a second interval performance state.

In the AT performance state, by having the auxiliary performance execution means execute the auxiliary performance when all selected winning types are won, it is possible to win many medals while reducing medal consumption. Therefore, by transitioning to the AT performance state, the player can play more advantageously than in a non-AT performance state. Here, a pseudo bonus performance state is provided as the AT performance state. Each performance state (normal performance state, pseudo bonus performance state, non-advantageous performance state, preparation performance state, first interval performance state, continuous lottery performance state, second interval performance state) will be explained individually below.

(Each performance state)
The normal presentation state is a presentation state corresponding to the initial state among a plurality of presentation states. The presentation state control means 314 performs an AT lottery when any of the winning types "Strong Cherry", "Watermelon A", "Watermelon B", and "Strong Bell" is determined by the winning type lottery in the normal presentation state. The AT lottery is a lottery that determines the transition to the 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, when the AT lottery is won, the presentation state control means 314 transitions the presentation state to the pseudo bonus presentation state, which is the AT presentation state, after the premonition period has elapsed (1). Also, when a predetermined ceiling condition (for example, a predetermined number of plays in the normal presentation state is consumed consecutively) is satisfied in the normal presentation state without transitioning to the pseudo bonus presentation state (so-called ceiling reaching), the presentation state control means 314 transitions the presentation state to the pseudo bonus presentation state (1).

In the pseudo bonus presentation state, the auxiliary presentation is executed until a predetermined end condition (for example, the number of games played reaches a predetermined number of games) is met, and the player can obtain, for example, 3.5 expected coins in the pseudo bonus presentation state. In the pseudo bonus presentation state, two end conditions are mainly prepared. For example, if the end condition is that the number of games played reaches a predetermined number of games, two stages are set as the predetermined number of games, 30 and 80, and one of them is determined by lottery. In the pseudo bonus presentation state, the more games played, the more gaming profits the player will obtain. Therefore, the player will want the predetermined number of games to be 80 rather than 30. However, even if 30 is determined as the predetermined number of games, a promotion lottery is also held to increase the predetermined number of games of the auxiliary presentation from 30 to 80 during the number of games. Note that, in this example, the condition for ending the pseudo bonus presentation state is that the number of plays played reaches a predetermined number of plays, but instead, it may be that the number of times the auxiliary presentation that can win the maximum payout number reaches a predetermined number, or that the number of coins won (net increase in number of coins) reaches a predetermined number.

In the pseudo-bonus presentation state, when a predetermined end condition is satisfied, the presentation state control means 314 may transition the presentation state to a non-advantageous presentation state (2). At this time, the presentation state control means 314 transitions the advantageous section to a non-advantageous section once, and resets all information updated in the advantageous section. For example, if the previous pseudo-bonus presentation state was the first pseudo-bonus presentation state, that is, if it is a pseudo-bonus presentation state immediately after transition from a normal presentation state, the presentation state control means 314 transitions the presentation state to a non-advantageous presentation state and transitions the advantageous section to a non-advantageous section once. Also, if the previous pseudo-bonus presentation state was a pseudo-bonus presentation state that is a multiple of three (3rd, 6th, ...) without passing through the normal presentation state, the presentation state control means 314 transitions the advantageous section to a non-advantageous section once, and transitions the advantageous section to a non-advantageous section once.

Then, the presentation state control means 314 draws a lottery for a transition to the advantageous zone with a high probability (for example, 1/2), and after the number play is completed, returns to the advantageous zone and transitions the presentation state to the preparation presentation state (3). This is to avoid the pseudo bonus presentation state being forcibly terminated when the value counted in the advantageous zone reaches a predetermined value.

On the other hand, if the previous pseudo-bonus presentation state is not the first time, or is not a pseudo-bonus presentation state that is a multiple of three and does not pass through a normal presentation state, the presentation state control means 314 transitions the presentation state directly to the preparation presentation state without transitioning to a non-advantageous presentation state (4). This is to avoid the pseudo-bonus presentation state being forcibly terminated when the value counted in the advantageous zone reaches a predetermined value, while also preventing the advantageous zone from being terminated unnecessarily.

In the preparation performance state, the performance state control means 314 performs a lottery to determine whether to transition to the first interval performance state with a high probability (e.g., 1/2), and transitions the performance state to the first interval performance state based on the decision to transition to the first interval performance state (5).

The first interval presentation state continues until a predetermined end condition (for example, 40 plays are played) is met, during which time a lottery is held to continue the pseudo bonus presentation state. Unlike the pseudo bonus presentation state, the first interval presentation state has a smaller expected number of coins per unit play, and may even be a negative value. In this embodiment, if a favorable zone is won in a non-favorable zone, the presentation state is set to always become the first interval presentation state. Therefore, after the pseudo bonus presentation state ends, the presentation state will transition to the first interval presentation state even if the favorable zone continues or, as described above, if the zone transitions to a non-favorable zone. Then, when a predetermined end condition in the first interval presentation state is met, the presentation state control means 314 transitions the presentation state to a continuation lottery presentation state (6).

The continuation lottery presentation state continues until a predetermined end condition (e.g., five plays are played) is met, and finally, the result of the lottery for continuing the pseudo bonus presentation state in the first interval presentation state is announced. Unlike the pseudo bonus presentation state, the continuation lottery presentation state also has a small expected number of coins to be won per unit play in such a state, and may even be a negative value. If a transition (continuation) to the pseudo bonus presentation state has been determined in the first interval presentation state, the presentation state control means 314 transitions the presentation state to the pseudo bonus presentation state (7), and if a transition to the pseudo bonus presentation state has not been determined, the presentation state control means 314 returns the presentation state to the normal presentation state (8).

In this way, in this embodiment, once the pseudo bonus presentation state is entered, the player can accumulate medals by repeating the transition from the pseudo bonus presentation state → preparation presentation state → first interval presentation state → continuation selection presentation state, unless the player misses the continuation selection for the continuation selection presentation state.

In addition, in the preparation performance state, the performance state control means 314 draws a lottery for transition to the second interval performance state in addition to drawing a lottery for transition to the first interval performance state. However, the probability of transition to the second interval performance state (e.g., 1/20) is set smaller than the probability of transition to the first interval performance state (e.g., 1/2). In the preparation performance state, if a transition to the second interval performance state is determined before a transition to the first interval performance state is determined, the performance state control means 314 transitions the performance state to the second interval performance state based on the decision to transition to the second interval performance state (9). Note that, although an example of drawing a lottery for transition to the second interval performance state in the preparation performance state is given here, a lottery for transition to the second interval performance state may also be drawn in a non-advantageous performance state in a similar manner.

The second interval presentation state, like the first interval presentation state, continues until a predetermined end condition (e.g., 40 plays are played) is met, during which time a lottery is held to continue the pseudo bonus presentation state. Like the first interval presentation state, the second interval presentation state differs from the pseudo bonus presentation state in that the expected number of coins to be won per unit of play is small, and may even be a negative value.

However, the pseudo bonus presentation state is determined with a higher probability in the second interval presentation state than in the first interval presentation state. For example, in the first interval presentation state, the pseudo bonus presentation state is determined every 1/58 of a game for 40 games (50% chance of winning), and in the second interval presentation state, the pseudo bonus presentation state is determined every 1/25 of a game for 40 games (80% chance of winning). Then, when a predetermined end condition is met, the presentation state control means 314 transitions the presentation state to a continuous lottery presentation state (10). Once the transition to the second interval presentation state is determined, thereafter, there will be no transition to a non-advantageous presentation state, preparation presentation state, or first interval presentation state until the continuous lottery presentation state is missed, and the pseudo bonus presentation state will only transition to the second interval presentation state (11). Therefore, the player can always receive a continuation lottery with a high probability. In addition, once the transition to the second interval presentation state is determined, even if the transition to the pseudo bonus presentation state is not determined in the continuation lottery presentation state, the presentation state control means 314 immediately transitions the presentation state to the non-advantageous presentation state without returning it to the normal presentation state (12). Therefore, if the transition to the pseudo bonus presentation state is not determined in the continuation lottery presentation state, the transition from the pseudo bonus presentation state to the preparation presentation state to the first interval presentation state to the continuation lottery presentation state can be repeated until the continuation lottery of the continuation lottery presentation state is missed again. In this way, once the transition to the second interval presentation state is made, the transition from the pseudo bonus presentation state to the second interval presentation state to the continuation lottery presentation state can be repeated with a high probability, and further, even if the transition to the pseudo bonus presentation state is not determined in the continuation lottery presentation state, the transition from the pseudo bonus presentation state to the preparation presentation state to the first interval presentation state to the continuation lottery presentation state can be repeated at least again, so that the player can accumulate more medals. In other words, the second interval presentation state is more advantageous than the first interval presentation state.

As described above, when transitioning from the pseudo bonus presentation state to the second interval presentation state, the presentation state control means 314 does not transition to a non-advantageous zone, unlike the transition to the first interval presentation state. In this embodiment, if the pseudo bonus presentation state is the initial pseudo bonus presentation state, the presentation state control means 314 does not transition to the second interval presentation state, but transitions the advantageous zone to a non-advantageous zone once, and always transitions to the first interval presentation state. In this way, the advantageous zone is reset once. Therefore, even if the advantageous zone is not reset when transitioning to the second interval presentation state, the pseudo bonus presentation state that passes through the second interval presentation state will not end in a short period due to the limitation of the advantageous zone, and the player can obtain many medals by looping the pseudo bonus presentation state → second interval presentation state → continuous lottery presentation state.

(Normal performance state)
11 is a diagram for explaining the premonition effect in the normal performance state. As described above, in the normal performance state, when any of the winning types "Strong Cherry", "Watermelon A", "Watermelon B", and "Strong Bell" (these may be collectively referred to as "Rare Role") is determined by the winning type lottery, the AT lottery is performed. Then, when the AT lottery is won, the performance state is shifted to the pseudo bonus performance state after a predetermined number of games (the main premonition period, up to 32 games) has elapsed.

Then, when the winning type "rare role" is won, the effect control means 334 executes a premonition effect that suggests or notifies the result of the AT lottery, regardless of the result of the AT lottery. Note that below, the premonition effect will be explained, and other effects will be omitted. Also, the premonition effect executed when the AT lottery is won will be called the real premonition effect, and the premonition effect executed when the AT lottery is not won will be called the false premonition effect.

Here, if the AT lottery is won, the real premonition effect is executed for the real premonition period, and if the AT lottery is not won, the false premonition effect is executed for the false premonition period (32 plays). Note that the real premonition period and the false premonition period may be simply referred to as the premonition period.

During normal display mode, as shown in FIG. 11(a), three count display areas 400a, 400b, and 400c are provided on the left side of the LCD display unit 124.

Count display area 400a corresponds to the winning type "strong cherry", count display area 400b corresponds to the winning types "watermelon A" and "watermelon B", and count display area 400c corresponds to the winning type "strong bell".

Then, if the winning type "Strong Cherry" is determined by the winning type lottery, the presentation control means 334 displays the value "33" in the count display area 400a during the game or until the game ends and the next game starts, as shown in FIG. 11(b), regardless of whether the winning type "Strong Cherry" is won or not.

When the next game is started, the presentation control means 334 subtracts 1 from the value displayed in the count display area 400a to display the value "32", as shown in FIG. 11(c). The presentation control means 334 subtracts 1 from the value displayed in the count display area 400a each time a game is played, and when the value displayed in the count display area 400a is "1" as shown in FIG. 11(d), the presentation control means 334 makes the value displayed in the count display area 400a invisible when the next game is started as shown in FIG. 11(e).

In this way, the count display area 400a continues to display the value for 32 games (excluding games in which the winning type "rare role" is won), so it can be said that the premonition effect is being executed while the value is displayed in the count display area 400a. And, if the AT lottery is won, the fact that the AT lottery has been won is notified while the value is displayed in the count display area 400a.

When the winning type is determined by the winning type lottery to be, for example, "Watermelon A," the presentation control means 334 displays "33" in the count display area 400b, and when the winning type is determined by the winning type lottery to be, for example, "Strong Bell," the presentation control means 334 displays "33" in the count display area 400c. Then, each time a game is played (when a specified condition is met), the presentation control means 334 subtracts one from the values displayed in the count display areas 400b and 400c. Also, when values are displayed in all of the count display areas 400a, 400b, and 400c, each time a game is played (when a specified condition is met), all values are subtracted one in parallel.

12 is a diagram explaining the premonition effect when the winning type "rare role" is determined during the premonition period. For example, assume that the winning type "strong cherry" is determined, the AT lottery is not won, and the false premonition effect is started. Then, after 12 games have passed, "20" is displayed in the count display area 400a as shown in FIG. 12(a). Then, assume that the next game is started, and the winning type "strong bell" is determined by the winning type lottery. At this time, the effect state control means 314 performs the AT lottery based on the winning type "strong bell", and also performs the AT lottery again based on the winning type "strong cherry" that triggered the start of the false premonition effect. Then, the effect control means 334 displays "33" in the count display areas 400a and 400c corresponding to the winning type "strong cherry" and the winning type "strong bell" as shown in FIG. 12(b).

In this way, if a winning type "rare role" different from the winning type that triggered the start of the false premonition effect is determined during the execution of the false premonition effect, the AT lottery is performed based not only on the winning type "rare role" but also on the winning type that triggered the start of the false premonition effect, and "33" is displayed in the count display areas 400a, 400b, and 400c corresponding to these winning types. In this case, premonition effects will be started for two winning types.

In addition, when values are displayed in two of the count display areas 400a, 400b, and 400c, that is, when premonition effects are being performed for two winning types "rare roles", if a winning type "rare role" (here, the winning type "watermelon A") for which no premonition effects are being performed is determined by the winning type lottery, the performance state control means 314 performs an AT lottery based on each of the winning types "strong cherry", "watermelon A", and "strong bell", and performs a special AT lottery due to all values being displayed in the count display areas 400a, 400b, and 400c (premonition effects have started for the three winning types "rare roles"), as will be described in detail later. Then, the performance control means 334 displays "33" in the count display areas 400a, 400b, and 400c corresponding to the winning types "strong cherry", "watermelon A", and "strong bell", as shown in FIG. 12(c).

In this way, when a value is displayed in any of the count display areas 400a, 400b, 400c, that is, when a premonition effect is being performed for any of the winning types "rare role", if the winning type "rare role" that triggered the execution of the premonition effect is determined by the winning type lottery, the effect state control means 314 performs another AT lottery based on the winning type "rare role" that triggered the execution of the premonition effect. Then, the effect control means 334 displays "33" again in the count display areas 400a, 400b, 400c where the value is displayed.

If a winning type "rare role" is determined during the execution of this premonition effect, "33" will be displayed in one of the count display areas 400a, 400b, 400c corresponding to the determined winning type "rare role", and "33" will also be displayed in one of the count display areas 400a, 400b, 400c corresponding to the winning type "rare role" that triggered the execution of this premonition effect. However, when this premonition period ends, the premonition effect will be forcibly ended regardless of the value of the count display areas 400a, 400b, 400c.

Figure 13 is a diagram explaining the AT lottery table. Figure 13(a) is an AT lottery table corresponding to the winning type "Strong Cherry", Figure 13(b) is an AT lottery table corresponding to the winning types "Watermelon A" and "Watermelon B", Figure 13(c) is an AT lottery table corresponding to the winning type "Strong Bell", and Figure 13(d) is an AT lottery table referenced when all values are displayed in the count display areas 400a, 400b, and 400c.

In Figures 13(a) to 13(d), the probability of winning the AT lottery is expressed as a percentage (%). According to Figures 13(a) to 13(c), the probability of winning the AT lottery is set higher when the winning type "Strong Cherry" is determined than when the winning types "Watermelon A," "Watermelon B," and "Strong Bell" are determined. Also, the probability of winning the AT lottery is set higher when the winning type "Strong Bell" is determined than when the winning types "Watermelon A" or "Watermelon B" are determined.

For example, in the winning type lottery, the winning type "Strong Cherry" is set to have a lower probability of being determined than the winning types "Watermelon A," "Watermelon B," and "Strong Bell," and the winning type "Strong Bell" is set to have a lower probability of being determined than the winning types "Watermelon A" and "Watermelon B." Therefore, although the winning types "Watermelon A" and "Watermelon B" are likely to be determined in the winning type lottery, they are difficult to win in the AT lottery. On the other hand, the winning type "Strong Cherry" is difficult to determine in the winning type lottery, but is easier to win in the AT lottery.

In such a case, after winning the winning type "Strong Cherry", if the winning types "Watermelon A" and "Watermelon B", which are relatively more likely to be determined, are determined while the premonition effect (false premonition effect) for the winning type "Strong Cherry" is being executed, the AT lottery will be held again for the winning type "Strong Cherry", which is more likely to be determined in the AT lottery, and the probability of winning in the AT lottery will increase compared to when the AT lottery is held only based on the winning types "Watermelon A" and "Watermelon B".

In other words, in the slot machine 100, by continuing to get the winning type "rare role" while the premonition effect (false premonition effect) is continuing, the AT lottery will be repeatedly performed based on the winning type "rare role" that has been determined up to that point, so the player will play while hoping that another winning type "rare role" will be determined during the execution of the premonition effect, which will increase the player's motivation to play.

In addition, if values are all displayed in the count display areas 400a, 400b, and 400c while the premonition effect (false premonition effect) is continuing, the AT lottery is performed by referring to the AT lottery table shown in FIG. 13(d). According to this AT lottery table, the winning probability of the AT lottery is set higher than the AT lottery tables shown in FIG. 13(a) to FIG. 13(c). In other words, by determining all of the winning types of "rare roles" while the premonition effect (false premonition effect) is continuing, the game has a playability in which the winning probability of the AT lottery is significantly higher.

(Challenge performance)
Fig. 14 is a diagram for explaining the challenge effect. When the false premonition effect is executed over 31 games, for example, "2" is displayed in the count display area 400a as shown in Fig. 14(a). Then, the false premonition effect ends in the next game. However, as described above, in this embodiment, the winning type "rare role" is determined while the false premonition effect is being executed, and the right to receive the AT lottery based on the winning type "rare role" determined during the execution of the false premonition effect up to that point comes again, so even if the player knows that it is a false premonition effect, the player wants the false premonition effect to continue.

Therefore, in the 32nd game of the false premonition effect, if any of the winning types "Symbol Replay A1" to "Symbol Replay B6" is determined, the effect state control means 314 determines whether or not to execute the challenge effect by drawing a lottery with a predetermined probability. Then, if it is determined that the challenge effect should be executed, the effect control means 334 displays a message on the liquid crystal display unit 124 urging the player to display (stop) the "BAR2" symbol (predetermined symbol) on the invalid line B1 (predetermined position) as shown in FIG. 14(b), and executes an auxiliary effect that causes the player to operate the stop switches 120a, 120b, and 120c in batting order 3 or batting order 4.

As described above, when one of the winning types "Symbol Replay A1" to "Symbol Replay B6" is determined and the stop switches 120a, 120b, and 120c are operated in batting order 3 or batting order 4, the "BAR2" symbol that is displayed (stopped) on the invalid line B1 differs for each of the winning types determined to be "Symbol Replay A1" to "Symbol Replay B6" (see FIG. 8 and its explanation).

The "BAR2" symbol displayed on the inactive line B1 of the left reel 110a corresponds to the winning type "Strong Cherry", the "BAR2" symbol displayed on the inactive line B1 of the center reel 110b corresponds to the winning types "Watermelon A" and "Watermelon B", and the "BAR2" symbol displayed on the inactive line B1 of the right reel 110c corresponds to the winning type "Strong Bell".

For example, when the winning type "symbol replay A2" is determined and the "BAR2" symbol is displayed on the invalid line B1 of the center reel 110b as shown in FIG. 14(c), it is treated as winning the winning type "watermelon A" or "watermelon B". In other words, when the winning type "symbol replay A2" is determined and the "BAR2" symbol is displayed on the invalid line B1 of the center reel 110b, the AT lottery is performed by referring to the AT lottery table corresponding to the winning types "watermelon A" and "watermelon B" shown in FIG. 13(b). In addition, the AT lottery is also performed based on the winning type "strong cherry" that triggered the execution of the false premonition effect. Then, the effect control means 334 displays "33" in the count display areas 400a and 400b corresponding to the winning types "strong cherry" and "watermelon" as shown in FIG. 14(d).

When one of the winning types "Symbol Replay A1" to "Symbol Replay B6" is determined and a challenge effect is decided to be executed, even if the "BAR2" symbol that should be displayed on the invalid line B1 is not displayed depending on the timing of the player's operation of the stop switches 120a, 120b, and 120c, the winning type "Rare combination" corresponding to the "BAR2" symbol that should be displayed is treated as having been determined.

In this way, when the value of the count display areas 400a, 400b, 400c reaches "1," a special bonus such as an AT lottery based on the displayed (stopped) symbols is awarded with a certain probability, allowing the player to play until the end without giving up during the premonition performance, thereby increasing the player's motivation to play.

Here, the stop control of the reels 110a, 110b, and 110c in the challenge effect will be described in detail. As described above, when the execution of the challenge effect is decided, if any of the winning types "Symbol Replay A1" to "Symbol Replay B6" is decided, the player can display the symbol combination corresponding to the winning role "Replay 3" on the activated line A. However, the symbol combination displayed differs depending on which of the winning types "Symbol Replay A1" to "Symbol Replay B6" is decided. Therefore, as explained using FIG. 8, the reel control means 306 changes the stop control based on which of the winning types "Symbol Replay A1" to "Symbol Replay B6" has been won, and displays one to three symbols "BAR2" on the inactive line B1.

Specifically, the reel control means 306 specifies a reel capable of displaying the symbol "BAR2" (predetermined symbol) on the void line B1 (predetermined position) based on the determined winning type. For example, as described with reference to FIG. 8, when the winning type "symbol replay A1" is determined, the left reel 110a is specified as a reel capable of displaying the symbol "BAR2", when the winning type "symbol replay A2" is determined, the center reel 110b is specified, when the winning type "symbol replay A3" is determined, the left reel 110a and center reel 110b are specified, when the winning type "symbol replay A4" is determined, the right reel 110c is specified, when the winning type "symbol replay A5" is determined, the left reel 110a and right reel 110c are specified, when the winning type "symbol replay A6" is determined, the center reel 110b and right reel 110c are specified, and when the winning type "symbol replay A7" is determined, the center reel 110b and right reel 110c are specified, and when the winning type "symbol replay A8" is determined, the left reel 110a and right reel 110c are specified, and when the winning type "symbol replay A9" is determined, the center reel 110b and right reel 110c are specified, and when the winning type "symbol replay A10" is determined, the center reel 110b and right reel 110c are specified, and when the winning type "symbol replay A20" is determined, the center reel 110b and right reel 110c are specified, and when the winning type "symbol replay A12" is determined, the center reel 110b and right reel 110c are specified, and when the winning type "symbol replay A13" If "Symbol Replay A7" is determined, the left reel 110a, the middle reel 110b, and the right reel 110c are specified; if "Symbol Replay B1" is determined, the left reel 110a is specified; if "Symbol Replay B2" is determined, the middle reel 110b is specified; if "Symbol Replay B3" is determined, the left reel 110a and the middle reel 110b are specified; if "Symbol Replay B4" is determined, the right reel 110c is specified; if "Symbol Replay B5" is determined, the left reel 110a and the right reel 110c are specified; if "Symbol Replay B6" is determined, the middle reel 110b and the right reel 110c are specified.

When the player operates the stop switches 120a, 120b, and 120c, the reel control means 306 acquires information on the stop switch 120 operated by the player. Next, the reel control means 306 determines whether or not the identified reel 110 capable of displaying the symbol "BAR2" on the invalid line B1 corresponds to the operated stop switch 120. For example, if the identified reels 110 include the center reel 110b and the stop switch 120 operated by the player is the stop switch 120b, it is determined that the two correspond to each other. If it is determined that they correspond to each other, the reel control means 306 sets the stop control table so that the symbol "BAR2" of the reel 110 corresponding to the operated stop switch 120 is preferentially displayed on the invalid line B1. Here, the stop control table is a table for determining the number of sliding frames for stop control.

In this embodiment, a logical operation is used to determine whether the identified reel 110 corresponds to the operated stop switch 120. For example, the reel control means 306 derives a bit string (displayable bit string) indicating a reel that can display the symbol "BAR2" on the inactive line B1, obtains the operated stop switch 120 as a bit string (operation bit string), and calculates the logical product of the displayable bit string and the operation bit string to determine whether the two correspond to each other. This configuration reduces the storage capacity of the program and ensures the capacity of the control area for performing game control processing.

In addition, in this embodiment, two stop control tables (stop control tables) are provided as tables for determining the number of slipping frames in the stop control: a first stop control table that performs stop control so that the symbol "BAR2" is preferentially displayed on the invalid line B1, and a second stop control table that performs stop control so that symbols other than the symbol "BAR2" are preferentially displayed on the invalid line B1. This configuration makes it possible to appropriately execute stop control while reducing the storage capacity of the program.

Below, we will explain the electrical configuration around the main CPU 200a, and then provide a detailed explanation of how the challenge performance is stopped.

(Memory and register management by main CPU 200a)
As described above, in the main control board 200, the main CPU 200a cooperates with the main RAM 200c based on the programs stored in the main ROM 200b to function as initialization means 300, betting means 302, winning type selection means 304, reel control means 306, determination means 308, payout control means 310, game state control means 312, presentation state control means 314, command transmission means 316, etc., and controls the progress of the game. The programs for executing these functional units are arranged in predetermined areas (usage areas) of the main ROM 200b and the main RAM 200c.

Figure 15 is an explanatory diagram showing a memory map. Here, the main ROM 200b is assigned a memory space of 0000h to 2FFFh (12 kbytes), and the main RAM 200c is assigned a memory space of F000h to F3FFh (1 kbyte). Here, "h" indicates a hexadecimal number. In addition, the areas to be used are defined in both the main ROM 200b and the main RAM 200c. The instruction codes of the program are written in assembler language. Here, a program is composed of instruction codes, and is read by a computer to realize a specified process in cooperation with data and a work area.

The memory space of 0000h to 1DF3h of the main ROM 200b is assigned as a usage area. Specifically, the memory space (control area) limited to 0000h to 11FFh (4.5kbytes) stores instruction codes of a program for executing a game control process that controls the progress of a game by making the initialization means 300, betting means 302, winning type lottery means 304, reel control means 306, judgment means 308, payout control means 310, game status control means 312, presentation status control means 314, and command transmission means 316 function, and the memory space (data area) limited to 1200h to 1DF3h (3.0kbytes) stores data used in the game control process program. In addition, the memory space of 1E00h to 1EFFh is assigned as a comment area, and the memory space of 2FC0h to 2FFFh is assigned as a program management area. In addition, a separate area is allocated to the memory space from 1F00h to 2FBFh. The separate area is an area for storing programs and data that are not specified to be stored in the used area. Specifically, the memory space from 2FC0h to 2FFFh stores instruction codes and program data of programs that perform some or all of the gaming machine test processing and security-related processing that do not affect the progress of the game. The gaming machine test processing is a test processing of the slot machine 100 described in the Connection Specifications (4th Edition) of the Test Machine for Slot Machines. The security-related processing is a process for identifying abnormal conditions for the purpose of preventing fraud by third parties and discovering defects, and includes, for example, the determination of the backup flag and the execution of a checksum as described above. There is no limit to the storage capacity of the separate area, and in the example of FIG. 15, it can be freely allocated to storage areas other than the used area, comment area, and program management area.

As described above, the main CPU 300a may perform not only game control processing, but also game machine test processing and security-related processing. However, the storage capacity of the usage area is predetermined; for example, as shown in FIG. 15, the control area is limited to 4.5 kbytes, and the data area is limited to 3.0 kbytes. Therefore, if not only game control processing but also programs and data for game machine test processing and security-related processing are placed in the usage area, the storage area for performing game control processing will be limited accordingly. Here, programs (usage programs) and data for executing game control processing must be stored in the usage area, but programs (other programs) and data for executing processing (game machine test processing, security-related processing, etc.) that does not affect (is not directly related to) the progress of the game other than the game control processing can be stored in either the usage area or the other area. Therefore, at least some of the programs and data for executing the security-related processes, such as the backup flag determination process and the checksum execution process, are written in a separate area that is part of a memory area different from the used area (outside the used area).

In this way, when there is a mixture of processing that is performed in the use area (here, game control processing) and processing that does not necessarily have to be performed in the use area (here, security-related processing), it is desirable to store the program (use program) and data for executing the game control processing in the use area, and store the program (separate program) and data for executing processing that does not have to be performed in the use area and does not affect the progress of the game other than the game control processing (gaming machine test processing, security-related processing) in a separate area. By dividing the memory area into multiple areas in this way, there is more space in the memory area (capacity) of the use area by the amount of the programs moved to the separate area. This makes it possible to allocate that much of the use area to the game control processing (use program).

In addition, the memory space from F000h to F1FFh in the main RAM 200c is assigned as a usage area. Specifically, the memory space from F000h to F13Fh is assigned as a work area for the above-mentioned game control process, and is used to manage variables such as timers, counters, and flags. The memory space from F1C0h to F1FFh is assigned as a stack area for the above-mentioned game control process. In addition, the memory space from F200h to F3FFh in the main RAM 200c is assigned as another area. Specifically, the memory space from F210h to F22Fh is assigned as a work area for some or all of the game machine test processes and security-related processes, and is used to manage variables such as timers, counters, and flags. The memory space from F230h to F246h is assigned as a stack area for some or all of the game machine test processes and security-related processes. In addition, the main CPU 200a is provided with an internal register.

Figure 16 is an explanatory diagram for explaining the internal registers of the main CPU 200a. Each internal register is composed of 8 bits or 16 bits, and may be used alone or in a predetermined combination (pair register). The internal registers are also divided into front registers and back registers that correspond to some of the front registers.

Of the internal registers shown in Figure 16, the Q register (queue register) is an 8-bit dedicated register with extended specifications for gaming machines. The most significant byte of this Q register is fixed at F0h, and is used to access the main RAM 200c from F000h to F0FFh. The I register is a dedicated register that stores the most significant 8 bits of the interrupt destination address. The A register is an 8-bit accumulator used for arithmetic processing and data transfer. The F register is an 8-bit flag register that holds the results of various arithmetic operations. Here, as shown in FIG. 16, from the most significant bit (MSB) to the least significant bit (LSB), the bits of the F register are as follows: S is a sign flag that is set to 1 when the result of the operation is negative; Z is a zero flag (first zero flag) that is set to 1 when all bits are 0 as a result of the operation; tz is a specific bit flag (second zero flag) for the gaming machine expansion specifications that is set to 1 (value changes) when all bits are 0 by executing a data transfer instruction (LD; load), and is sometimes called a tee-z flag. h is a half carry flag that cannot be controlled by the programmer; * is a reserved bit (undefined); p/v is a parity overflow flag; n is an addition/subtraction flag that cannot be controlled by the programmer; and c is a carry flag that is set to 1 when a carry or borrow occurs as a result of the operation. The F register and the A register form a pair register AF.

The B, C, D, E, H, and L registers are 8-bit general-purpose registers, and each of them constitutes a 16-bit pair register BC, DE, and HL, whose combinations are predefined. The IX and IY registers are 16-bit dedicated registers for index addressing, with IXh and IYh indicating the upper 8 bits, and IXl and IYl indicating the lower 8 bits. The A', F', B', C', D', E', H', and L' registers are back registers whose data (contents) can be exchanged with the front registers A, F, B, C, D, E, H, and L by an exchange command. The A' and F' registers constitute the pair register AF', the B' and C' registers constitute the pair register BC', the D' and E' registers constitute the pair register DE', and the H' and L' registers constitute the pair register HL'. These hidden registers function as a stack area for the visible registers when an interrupt occurs.

In this environment, the main CPU 200a performs game control processing that causes the initialization means 300, betting means 302, winning type selection means 304, reel control means 306, determination means 308, payout control means 310, game status control means 312, presentation status control means 314, and command transmission means 316 to function, in response to an interrupt signal, for example, every 1.49 msec, in accordance with the instruction code of the program in the usage area, while referring to the program data in the usage area, and by utilizing each internal register and the work area and stack area of the usage area.

In this example, the instruction code used is a command prepared for the LEM50A-P (product name) sold by LETech. The LEM50A-P is a microprocessor equipped with a Z80 series CPU called NC80EX, which is widely used in the gaming machine industry (it has a high market share).

In this way, in the main CPU 200a, the storage capacity of the areas used is predetermined; for example, as shown in FIG. 15, the control area is limited to 4.5 kbytes, and the data area is limited to 3.0 kbytes. Therefore, when the main CPU 200a manages the AT performance state and the so-called reel performance in which the reel unit is rotated in various ways, the storage capacity of the game control processing within the control area may be further limited. Here, the capacity of the control area for performing the game control processing is secured by devising the configuration of the program and the variables handled within the program.

(Challenge performance stop control program)
Fig. 17 is a flow chart for explaining the stop control of the challenge effect, and Fig. 18 is an explanatory diagram showing the calculation results in the stop control. Here, the main CPU 200a performs game control processing by command codes of a program (usage program) stored in the usage area in response to an interrupt signal, for example, every 1.49 msec. The main CPU 200a then executes a main routine, calls a subroutine from the main routine, and sets a stop control table in the subroutine.

First, the reel control means 306 determines whether the stop switch 120 that was first stopped is the stop switch 120b corresponding to the center reel 110b (S200). As a result, if the stop switch 120 that was first stopped is the stop switch 120b (YES in S200), the process proceeds to step S201, and if it is not the stop switch 120b (NO in S200), the process returns to the main routine. Through this process, the stop control of the challenge effect is realized in a game in which the stop switch 120b corresponding to the center reel 110b is first stopped.

Then, the reel control means 306 judges whether the winning type determined by the winning type lottery corresponds to any one of the winning types "symbol replay A1" to "symbol replay B6". This is realized by judging whether the winning area number in the winning type lottery table (arrangement number in the lottery table) is included in 27 (the winning area number of the winning type "symbol replay A1") to 39 (the winning area number of the winning type "symbol replay B6") (see FIG. 7). Specifically, the reel control means 306 refers to the winning area number of the winning type determined by the winning type lottery (arrangement number in the lottery table) (S201), and subtracts 27 (offset value), which is the winning area number of the winning type "symbol replay A1", from the winning area number (S202). Then, as shown in FIG. 18, the winning area numbers 27 to 39 can be replaced with 0 to 12.

Then, the reel control means 306 determines whether the subtracted value is less than the numerical value indicating the range of the winning types "Symbol Replay A1" to "Symbol Replay B6", i.e., 13 (39 (the winning area number of the winning type "Symbol Replay B6") - 27 (the winning area number of the winning type "Symbol Replay A1") + 1) (S203), and if it is less than 13 (YES in S203), the process proceeds to step S204, and if it is 13 or more (NO in S203), the process returns to the main routine.

Next, the reel control means 306 divides the subtraction value, which is the value obtained after subtracting 27 (offset value), by 7 (number of members), which is the number of members in the group in which the stop control modes are regularly grouped (S204). Here, examples of groups in which the stop control modes are regularly grouped include the group of winning types "Symbol Replay A1" to "Symbol Replay A7" and the group of winning types "Symbol Replay B1" to "Symbol Replay B6" shown in FIG. 7. In each of these two groups, the stop control is all different within the group, and the stop control modes are regularly arranged, with the stop control being equal between the groups. In this way, the subtraction value is divided by 7, which is the number of members in the group (winning types "Symbol Replay A1" to "Symbol Replay A7"), and the remainder is used to replace the member numbers 0 to 6 in the group, as shown in FIG. 18.

Next, the reel control means 306 adds 1 to the remainder obtained by the division to derive a displayable bit string (S205). Here, by adding 1 to the remainder range of 0 to 6, the range is shifted to 1 to 7 as shown in FIG. 18. In this way, a displayable bit string indicating a reel capable of displaying the symbol "BAR2" on the inactive line B1 is derived. For example, the displayable bit string for the winning type "symbol replay A1" is 001b. Here, "b" indicates a binary number. Here, bit 0 of the displayable bit string corresponds to the left reel 110a, bit 1 to the center reel 110b, and bit 2 to the right reel 110c. Therefore, the displayable bit string of 001b for the winning type "symbol replay A1" indicates that only the left reel 110a is a reel capable of displaying the symbol "BAR2" on the inactive line B1. Similarly, for the other winning types "Symbol Replay A2" to "Symbol Replay B6", the displayable bit strings correspond to the reels that can display the "BAR2" symbol on the inactive line B1, which is consistent with the example in Figure 8. Here, each bit in the displayable bit string directly indicates a reel that can display the "BAR2" symbol on the inactive line B1, so it can be easily and appropriately used in logical operations such as the logical product shown below.

Next, the reel control means 306 refers to the operation bit string indicating the stop switch 120 operated by the player from the input port (S206), and calculates the logical product of the operation bit string and the displayable bit string (S207). Here, bit 0 of the operation bit string corresponds to the stop switch 120a, bit 1 corresponds to the stop switch 120b, and bit 2 corresponds to the stop switch 120c. Therefore, when the stop switch 120a is operated, the operation bit string becomes 001b, when the stop switch 120b is operated, the operation bit string becomes 010b, and when the stop switch 120c is operated, the operation bit string becomes 100b. Note that two or three operations of the stop switches 120a, 120b, and 120c are not valid at the same time, so that the operation bit string has one of the bits 0, 1, and 2 as "1" and the other two bits as "0". Next, the reel control means 306 determines whether the logical product is 0 (S208), and if the logical product is 0 (YES in S208), it sets a second stop control table that controls the stops so that symbols other than the "BAR2" symbol are preferentially displayed on the inactive line B1 (S209) and returns to the main routine; if the logical product is not 0 (NO in S208), it sets a first stop control table that controls the stops so that the "BAR2" symbol is preferentially displayed on the inactive line B1 (S210) and returns to the main routine.

The flowchart shown in FIG. 17 is realized, for example, by the program in FIG. 19. "SCR_MSK" on the first line of FIG. 19 indicates the start address of the subroutine. "BITQ 1, (LOW _1ST_BIT)" on the second line indicates that if bit 1 of the value of the address (_1ST_BIT) indicating the first stopped stop switch 120 is 1, the zero flag is not set, and if it is 0, the zero flag is set. Here, command commands with "Q" such as "BITQ" are commands used exclusively by NC80EX, and the value of the Q register is set to the upper part of the IY register, and the address value of _1ST_BIT itself is set to the lower part of the IY register to access the address indicated by the IY register. Therefore, in command commands with "Q" attached, the lower byte of the address value of _1ST_BIT itself, which is composed of two bytes, is specified, so the address is written as "(LOW _1ST_BIT)". "RET Z" on the third line indicates that if the zero flag is set, return to the main routine, and if the zero flag is not set, proceed to the next process. The commands on the second and third lines correspond to step S200 in FIG. 17.

"LDQ A,LOW _HIT_NUM" on the fourth line of Figure 19 indicates that the value of the address (_HIT_NUM) indicating the number of the winning area determined by the winning type lottery is set in the A register. This command on the fourth line corresponds to step S201 in Figure 17. "SUB @HIT_ARE_SA1" on the fifth line indicates that the offset value of 27 (@HIT_ARE_SA1) is subtracted from the value in the A register. This command on the fifth line corresponds to step S202 in Figure 17. "CP @HIT_ARE_SB6-@HIT_ARE_SA1+1" on line 6 indicates that the value of the A register is compared with 13 (39 (the number of the winning area for the winning type "Symbol Replay B6") - 27 (the number of the winning area for the winning type "Symbol Replay A1") + 1), and if it is less than 13, the carry flag is set, and if it is 13 or greater, the carry flag is not set. "RET NC" on line 7 indicates that if the carry flag is set, proceed to the next process, and if the carry flag is not set, return to the main routine. These commands on lines 6 and 7 correspond to step S203 in FIG. 17.

"DIV B, A, 7" on line 8 of FIG. 19 indicates that the value of the A register is divided by 7 and the remainder is set in the B register. This command on line 8 corresponds to step S204 in FIG. 17. "INC B" on line 9 indicates that the value of the B register is incremented (added 1). This command on line 9 corresponds to step S205 in FIG. 17. "LD A, E" on line 10 indicates that the value of the E register, to which the value of the input port is set, is set in the A register. This command on line 10 corresponds to step S206 in FIG. 17. "AND B" on line 11 indicates that the logical product of the contents of the A register (operation bit string) and the contents of the B register (displayable bit string) is taken and set in the B register. Here, if the value after the logical product is 0, the zero flag is set, and if the value is other than 0, the zero flag is not set. This command on line 11 corresponds to step S207 in FIG. 17.

"RESQ 3, (LOW _USE_MSK)" on line 12 of FIG. 19 indicates that bit 3 of the address (_USE_MSK) for managing the stop control table is set to 0, and the second stop control table is temporarily set. "RET Z" on line 13 indicates that if the zero flag is set, the process returns to the main routine, and if the zero flag is not set, the process proceeds to the next step. "SETQ 3, (LOW _USE_MSK)" on line 14 indicates that bit 3 of the address (_USE_MSK) for managing the stop control table is set to 1, and the first stop control table is set. As a result, if the logical product is 0, the second stop control table is set, and if the logical product is not 0, the first stop control table is set. The commands on lines 12 to 14 correspond to steps S208 to S210 in FIG. 17. Then, "RET" on line 15 causes the process to return to the main routine.

In this embodiment, the reels that can display the "BAR2" symbol on the inactive line B1 and the operated stop switch 120 are represented by displayable bit strings and operation bit strings, respectively, and the stop control table to be used is simply and appropriately determined by the logical product of these. This configuration makes it possible to appropriately execute stop control while reducing the storage capacity of the program.

Once the stop control table is determined in this manner, the reel control means 306 controls the stop of the reel 110 corresponding to the operated stop switch 120 based on the operated stop switch 120, the rotational position of the reel 110 at the time of operation, and the information in bit 3 of the value of the address (_USE_MSK) (whether or not the first stop control table is set).

Figure 20 is an explanatory diagram showing a stop control table, and Figure 21 is an explanatory diagram showing an example of stop control. Here, as shown in Figure 14, an example is given in which the winning type "Symbol Replay A2" is won in the challenge performance, and the player operates stop switches 120a, 120b, and 120c in the batting order 4 in response to the auxiliary performance.

First, assume that the rotational position of the middle reel 110b when the player operates the stop switch 120b to make the first stop was the "Replay A" symbol with the symbol number "10". Note that, here, the symbol located in the upper row of the symbol display window 108 when the player operates the stop switch 120 is shown as an indicator of the rotational position. Therefore, here, at the timing when the player operates the stop switch 120b to make the first stop, the "Replay A" symbol with the symbol number "10" was located in the upper row of the symbol display window 108 on the middle reel 110b. Based on the operated stop switch 120b and the rotational position of the middle reel 110b when it was operated (here, the symbol number "10"), the reel control means 306 extracts the first stop control table and second stop control table for the symbol number "10" and the number of sliding frames "4" above that, as shown in FIG. 21(a), from the first stop control table and second stop control table for the middle reel 110b in FIG. 20.

Next, the reel control means 306 refers to bit 3 of the value of the address (_USE_MSK), and if bit 3 is 1, it checks the first stop control table in FIG. 21(a) from the bottom up (in descending order of symbol numbers) to determine whether or not a black circle is present. Here, the black circle indicates the symbol to be positioned in the upper row of the symbol display window 108 by stop control. In the example of FIG. 21(a), since a black circle exists for symbol number "6", the reel control means 306 performs stop control so that the symbol "cherry" for symbol number "6" is positioned in the upper row of the symbol display window 108.

If the player operates the stop switch 120b to the first stop and the rotation position of the middle reel 110b is the "cherry" pattern with the pattern number "11", the extracted first stop control table and second stop control table will be as shown in FIG. 21(b). Here, although bit 3 of the value of the address (_USE_MSK) is 1, there is no black circle in the first stop control table of FIG. 21(b). In this case, the reel control means 306 checks the first stop control table of FIG. 21(b) from the bottom up (in descending order of the pattern number), and when it is determined that there is no black circle, it continues by checking the second stop control table of FIG. 21(b) from the bottom up (in descending order of the pattern number). In the example of FIG. 21(b), since there is a black circle at the pattern number "9", the reel control means 306 performs stop control so that the "bell" pattern with the pattern number "9" is located at the top of the pattern display window 108. In this way, even if bit 3 of the address (_USE_MSK) value is 1, if there is no black circle in the first stop control table, that is, if the desired symbol (here, the symbol "cherry" with symbol number "6") does not exist within the range of the number of sliding frames, the second stop control table will be used.

Next, suppose that the player stops the stop switch 120c for the second time, and the rotation position of the right reel 110c when it is operated is the pattern "BAR2" with the pattern number "7". The reel control means 306 extracts the pattern number "7" and the first and second stop control tables for the number of sliding frames "4" above it from the first and second stop control tables of the right reel 110c in FIG. 20 based on the operated stop switch 120c and the rotation position of the right reel 110c when it is operated (here, the pattern number "7"), as shown in FIG. 21(c). However, since bit 3 of the value of the address (_USE_MSK) for the right reel 110c is 0, the reel control means 306 checks the second stop control table from the bottom (in descending order of the pattern number) without checking the first stop control table in FIG. 21(c) and determines whether a black circle exists. In the example of FIG. 21(c), since there is a black circle on the symbol number "3", the reel control means 306 controls the reel to stop so that the symbol "cherry" on the symbol number "3" is positioned at the top of the symbol display window 108.

Next, suppose that the player stops the stop switch 120a for the third time, and the rotation position of the left reel 110a when it was operated was the "Replay B" pattern with the pattern number "17". Based on the operated stop switch 120a and the rotation position of the left reel 110a when it was operated (here, the pattern number "17"), the reel control means 306 extracts the first stop control table and the second stop control table for the pattern number "17" and the number of sliding frames "4" above it, as shown in FIG. 21(d), from the first stop control table and the second stop control table for the left reel 110a in FIG. 20, as shown in FIG. However, for the left reel 110a, like the right reel 110c, bit 3 of the address (_USE_MSK) value is 0, so the reel control means 306 checks the second stop control table from the bottom up (in descending order of symbol numbers) without checking the first stop control table in FIG. 21(d) to determine whether or not a black circle is present. In the example of FIG. 21(d), since a black circle is present at symbol number "13," the reel control means 306 controls the reel to stop so that the "watermelon" symbol at symbol number "13" is positioned at the top of the symbol display window 108.

As such, as shown in FIG. 21(e), only the middle reel 110b, for which bit 3 of the address (_USE_MSK) value is 1, can display the symbol "BAR2" on the inactive line B1, while the right reel 110c and left reel 110a, for which bit 3 of the address (_USE_MSK) value is 0, cannot display the symbol "BAR2" on the inactive line B1.

Here, a stop control table is used to appropriately control the stopping of reels 110a, 110b, and 110c using uniform processing depending on whether bit 3 of the address (_USE_MSK) value is 1 or not.

Here, a first stop control table and a second stop control table are associated with each of the reels 110a, 110b, and 110c, and stop control is performed for each of the reels 110a, 110b, and 110c as to whether or not the symbol "BAR2" is displayed on the invalid line B1. This makes it possible to reduce the storage capacity of the program compared to creating 8 (2^3) stop control tables for all of the reels 110a, 110b, and 110c.

The specific processing on the main control board 200 is explained below based on the flowchart.

(Main processing of main control board 200)
22 is a flow chart showing the main processing of the main control board 200. First, an outline of one game after initialization will be described along with the main processing of the main control board 200, and then each process will be described in detail. Also, the processes related to the features of this embodiment will be described in detail, and the configuration unrelated to the features of this embodiment will not be described. Also, although a detailed description will be omitted, when each process is performed, the switches used in each process (bet switch 116, start switch 118, stop switches 120a, 120b, 120c) are enabled at the start of the process and disabled at the end of the process.

(Step S100)
When the slot machine 100 is powered on via the power switch 144 and enters a powered state, the initialization means 300 executes an initialization process in preparation for the start of a game. The initialization means 300 generates backup data at any time while the power is on, and stores the backup data in the main RAM 200c. Therefore, even if an unexpected power interruption occurs, the initialization process can use the stored backup data to restore the state before the power interruption. For example, even if an unexpected power interruption occurs while the reels 110 are rotating, the game starts from a state in which each reel 110 is rotating again after a recovery operation. Therefore, the initialization process does not basically initialize the main RAM 200c (RAM clear).

(Step S200)
Next, the betting means 302 bets medals when the player operates the bet switch 116 or inserts medals into the medal insertion unit 114. In addition, the command transmission means 316 generates an insertion command indicating that the operation has been performed, and transmits the generated insertion command to the sub-control board 202.

(Step S300)
Next, the winning type selection means 304 validates the game start operation on the start switch 118 and transitions to a state of waiting for the operation of the start switch 118. Here, the winning type selection means 304 acquires one winning type selection random number at the time when the start switch 118 is operated from the winning type selection random numbers updated by the random number generator 200d of the main control board 200 in response to the operation of the start switch 118 by the player. Then, the winning type selection means 304 determines one winning type selection table corresponding to the currently set game state from the winning type selection tables shown in FIG. 6 and FIG. 7, and determines which winning area in the determined winning type selection table the acquired winning type selection random number corresponds to, and determines the winning type or non-winning of the determined winning area as the lottery result. In addition, when the winning role "RBB" is determined in the winning type selection lottery, the game state control means 312 transitions the game state from the non-internal game state to the RBB internal game state.

In addition, after the lottery result is determined in response to the operation of the start switch 118, the command sending means 316 generates a winning type command including the lottery result of the winning type lottery (winning type or no winning) and information about the game status, and sends the generated winning type command to the sub-control board 202.

(Step S400)
When the start switch 118 is operated, the reel control means 306 drives the stepping motor 152 to rotate the left reel 110a, the center reel 110b, and the right reel 110c. In this reel rotation process, when a predetermined time (e.g., 4.1 seconds) has elapsed from the start of rotation of the left reel 110a, the center reel 110b, and the right reel 110c in the previous game (wait), the left reel 110a, the center reel 110b, and the right reel 110c in the game start to rotate, and when all of the left reel 110a, the center reel 110b, and the right reel 110c have reached a steady rotation, the process proceeds to step S500.

(Step S500)
Next, the reel control means 306 activates the stop switches 120a, 120b, and 120c, and when it receives an operation of the stop switches 120a, 120b, and 120c by the player, it controls to stop any of the left reel 110a, the center reel 110b, and the right reel 110c corresponding to the operation. In addition, when any of the stop switches 120a, 120b, and 120c is operated, the command sending means 316 generates a stop command (first stop command, second stop command, third stop command) indicating information of the operated stop switch 120a, 120b, and 120c each time the switch is operated, and sends the generated stop commands to the sub-control board 202 in sequence.

(Step S600)
Next, the determination means 308 determines which of the predetermined combinations corresponds to the symbol combination displayed on the pay line A shown in FIG. 3(b) (the winning combination that won the prize). In addition, the game state control means 312, in the RBB inside game state, if the symbol combination displayed on the pay line A corresponds to the winning combination "RBB", shifts the game state from the RBB inside game state to the RBB operation game state. In addition, the command transmission means 316 generates a winning command including the number of medals to be paid out when the symbol combination displayed on the pay line A or the symbol combination corresponding to the minor role is displayed on the pay line A, and transmits the generated winning command to the sub-control board 202.

(Step S700)
Furthermore, the payout control means 310 executes a payout process of medals corresponding to a minor winning combination based on the symbol combination displayed on the active line A (stopping state of the reel 110), for example, when a symbol combination corresponding to a minor winning combination is displayed on the active line A, and automatically executes a process for placing a bet for the next game when a symbol combination corresponding to a replay winning combination is displayed on the active line A. Furthermore, when a medal payout process has been performed, the command sending means 316 generates a payout command indicating that the payout process has been performed, and sends the generated payout command to the sub-control board 202.

(Step S800)
When a predetermined number of medals are paid out in the RBB-operated game state, the game state control means 312 transitions the game state from the RBB-operated game state to a non-internal game state. The presentation state control means 314 changes the presentation state and changes between advantageous and non-advantageous zones. When the game state or presentation state is changed, the command sending means 316 generates a game transition command including the changed game state or presentation state, and sends the generated game transition command to the sub-control board 202. In this way, the transition process S800 ends, and the game ends.

When it is notified that a transition to the pseudo bonus presentation state has been decided, the presentation state control means 314 causes the reel control means 306 to execute a first reel presentation indicating a transition to the pseudo bonus presentation state described above, and the pseudo bonus presentation state is started from the next play.

One game is executed through a series of processes from step S200 to step S800. After that, steps S200 to S800 are repeated.

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 embodiment, when the winning type "Symbol Replay A1" to "Symbol Replay B6" is determined on the condition that a challenge effect is executed with a predetermined probability on the 32nd play of the false premonition effect, an example was given in which it is determined whether or not the "BAR2" symbol on each of the reels 110a, 110b, and 110c can be displayed on the invalid line B1. However, it is possible to apply a game feature in which it is determined whether or not the "BAR2" symbol on each of the reels 110a, 110b, and 110c can be displayed on the invalid line B1 at various times, not limited to when a challenge effect is executed on the 32nd play of the false premonition effect.

In addition, in the above-mentioned embodiment, the replay role, in particular the winning role "Replay 3" was given as the specific role, but this is not limited to the above case. It is sufficient that the stop control is different in one condition device (when one of multiple winning types including the specific role is determined by the winning type lottery, the specific role is stopped and controlled so that the display mode differs according to the determined winning type), and it may be another replay role or a minor role other than the replay role.

In addition, in the above-described embodiment, the predetermined position is exemplified as being on the invalid line B1, and the predetermined pattern is exemplified as being the pattern "BAR2", but it goes without saying that either can be set arbitrarily.

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 addition, in the above-described embodiment, only one type of AT presentation state is provided, but multiple types of AT presentation states may be provided, such as a specialized zone for adding the number of continued plays in the AT presentation state.

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.
