Description

[Technical Field]

[0001] The present invention relates to a gaming machine. [Background technology]

[0002] Conventionally, gaming machines (slot machines) equipped with multiple reels with symbols arranged on their outer peripheries have been known. These types of gaming machines assign a certain gaming value to gaming media such as medals or pachinko balls, and players play to acquire these gaming media. Furthermore, these types of gaming machines perform an internal lottery and start the rotation of the multiple reels when the player initiates a spin operation, and stop the multiple reels in a manner corresponding to the results of the internal lottery when the player initiates a stop operation. The game result is determined by the symbol combination displayed on a winning determination line when the multiple reels are stopped, and medals or other items are paid out according to the game result.

[0003] In the gaming machine described above, a configuration is known in which, when a predetermined role that can be won in a predetermined gaming state and a bonus state is won, the pattern that is displayed stopped on the pay line can be changed depending on the gaming state (for example, Patent Document 1).

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described. Note that the embodiment described below does not unduly limit the content of the present invention described in the claims. Furthermore, not all of the configurations described in the embodiment are necessarily essential constituent elements of the present invention.

[0011] 1. Overview of the gaming machine configuration FIG. 1 is a perspective view showing the exterior configuration of a slot machine 1 according to an embodiment of the present invention. The slot machine 1 of this embodiment is a so-called reel-type gaming machine, and is configured as a medal-less gaming machine in which gaming value available to a player is recorded electromagnetically based on a lending signal output from a dedicated unit SU (see FIG. 2) provided outside the slot machine 1 and configured to lend and settle medals that constitute gaming value electromagnetically. The slot machine 1 is configured to store information on the number of recorded electronic medals as the number of gaming medals and to transmit the stored number of gaming medals to the dedicated unit SU. The dedicated unit SU records the number of gaming medals received from the slot machine 1 on a recording medium such as an IC card and dispenses it to settle the electronic medals.

[0012] The slot machine 1 of this embodiment is housed in a box-shaped cabinet consisting of a cabinet BX, an upper front door UD, and a lower front door DD, and houses a reel unit RU consisting of a left reel R1 to a right reel R3 as multiple reels. The cabinet of the slot machine 1 of this embodiment also houses a control board that is equipped with a CPU, ROM (an example of an information storage medium), RAM, etc. and controls the operation of the slot machine 1.

[0013] The outer periphery of each of the left reel R1 to right reel R3 shown in Figure 1 is divided into 20 areas (hereinafter, each area will be referred to as a "frame") at regular intervals, and one of several types of patterns is arranged in each frame.

[0014] The upper front door UD and the lower front door DD can be opened and closed separately. The upper front door UD is provided with a display device 410 as a display means for displaying various videos and images to assist and enhance the game. The display device 410 has a display area 410a for displaying images, and a specific area 410b facing the left reel R1 to the right reel R3 is made up of a transparent liquid crystal display. The display device 410 is configured so that the spinning and stopped states of the left reel R1 to the right reel R3 can be observed through the display device 410. When the left reel R1 to the right reel R3 are stopped, three consecutive symbols (top, middle, and bottom symbols) arranged on the outer periphery of each of the left reel R1 to the right reel R3 can be observed from the front of the slot machine 1 through the display device 410. Among the multiple types of symbols arranged at regular intervals on the outer periphery of each of the left reel R1 to the right reel R3, three symbols arranged consecutively on the outer periphery can be observed through the display device 410.

[0015] In the slot machine 1 of this embodiment, each reel is provided with an upper row, a middle row, and a lower row as display positions for observing symbols through the display device 410, and an activated line L1 is set for an activated line formed by a combination of the display positions of each reel. In the slot machine 1 of this embodiment, the number of medals required for one game, the so-called specified number (specified number), is set to three (first specified number) or two (second specified number), and when medals equivalent to the specified number are inserted, the activated line L1 formed by the middle row of the left reel R1 to the right reel R3 is activated.

[0016] The game result is determined by the symbol combination stopped and displayed on the valid line L1 (valid line), and if the symbol combination on the valid line L1 is a symbol combination corresponding to a predetermined role, that role is considered to have won, and control according to the winning role is executed.

[0017] The lower front door DD is provided with various operating means, such as a max bet button MB as an inserting operation means for setting the medals stored in the slot machine 1 to an inserted state, a start lever SL as a game start operation means for allowing the player to perform a start operation that triggers the left reel R1 to the right reel R3 to spin and start a game, stop buttons B1 to B3 as stop operation means for allowing the player to perform a stop operation that triggers the left reel R1 to the right reel R3 that are rotated by a stepping motor, a counting button KB as a counting operation means for transmitting the number of game medals stored in the slot machine 1 to the dedicated unit SU, and a settlement button AB for performing a settlement operation that cancels the inserted state and returns the electronic medals that have been set to the inserted state to the medal count counter 311 (see FIG. 2).

[0018] In addition, the lower front door DD is provided with a main control display device 10D controlled by the CPU of the main control board 10 (see FIG. 2). The main control display device 10D is composed of a 7-segment display or the like, and displays various game information such as information on the winning combination in the current game, and information (alert display) suggesting how to press stop button B1, stop button B2, and stop button B3 related to the payout of medals. The alert display displayed on the main control display device 10D corresponds to a winning combination command, which is a control signal created based on winning information, which is information on the winning combination in the current game, when a specified number of medals are inserted and the start lever SL is operated.

[0019] In addition, the front lower door DD is provided with a game medal count display device MD controlled by a medal count control CPU 31 (see Figure 2). The game medal count display device MD is made up of a 7-segment display or the like, and functions as a conceptual receptacle by displaying the number of game medals stored in the slot machine 1.

[0020] The front lower door DD is provided with a plurality of sound devices 420 for producing sound effects. The sound devices 420 output a variety of sounds to assist and liven up the game.

[0021] FIG. 2 is a functional block diagram of the slot machine 1 of this embodiment. The slot machine 1 of this embodiment has, as control boards, a main control board 10, a sub-control board 20, and a medal count control board 30. The main control board 10 has a main control CPU 11 (game control means) that controls the progress of the game by controlling the game played using game values. The sub-control board 20 has a sub-control CPU 21 that controls the presentation related to the game. The medal count control board 30 has a medal count control CPU 31 that manages electronic medals and controls the number of game medals by being configured to be able to communicate with the dedicated unit SU.

[0022] The main control CPU 11 functions as setting change means 100, deposit acceptance means 105, random number generation means 110, internal lottery means 120, reel control means 130, winning determination means 140, payout control means 150, game state transition control means 160, assist time control means (AT control means) 170, and complete control means 180. Each means constituting the main control CPU 11 reads out and executes each control program stored in advance in main storage means 190 when executing each control process.

[0023] The setting change means 100 performs control (setting change control) to change the setting values ​​stored in the setting value storage means 191 of the main storage means 190. The setting change means 100 operates when a setting key is inserted into a setting key cylinder KC provided on the main control board 10 and the setting key is turned, turning on the setting change switch SS provided inside the setting key cylinder KC. When the power is turned on with the setting change switch SS in the ON state, the setting change means 100 transitions to a setting change permitted state in which setting changes are permitted. On the other hand, the setting change means 100 is configured not to transition to the setting change permitted state when the setting change switch SS is in the ON state while the power is on.

[0024] In the setting change permitted state, the setting change means 100 cyclically changes the setting value in the order of Setting 1 → Setting 2 →... → Setting 6 → Setting 1 →... each time it receives an input signal output by operating the setting change button BS provided on the power supply device, and determines the setting value based on receiving a start signal output by operating the start lever SL. In the slot machine 1, the winning probability of some of the winning areas that can be won in the internal lottery by the internal lottery means 120 is changed according to the setting value determined in the setting value storage means 191. In other words, the setting change means 100 is configured to be able to change the setting value, which is a value that can change the winning probability of a combination in the internal lottery by the internal lottery means 120.

[0025] In the slot machine 1 of this embodiment, when the setting change control is executed by the setting change means 100, the control relating to the game state executed by the game state transition control means 160 and the control relating to the advantageous zone executed by the AT control means 170 are configured to be initialized, the game state is set to a non-replay time (hereinafter, replay time is also referred to as "RT") state described later, and the control relating to the auxiliary game executed by the AT control means 170 before the setting change is also initialized and a normal zone is set. Meanwhile, in the slot machine 1, when the supply of power to the main control CPU 11 is cut off (power interruption) and then the supply of power is resumed, the control relating to the game state executed by the game state transition control means 160 and the control relating to the advantageous zone executed by the AT control means 170 are configured to be resumed from the state before the power interruption, and the control relating to the auxiliary game executed by the AT control means 170 before the power interruption is also configured to be maintained in the state before the power interruption.

[0026] The deposit acceptance means 105 accepts an input signal output when the max bet button MB is operated (bet operation) while a number of game medals equal to or greater than a specified number is stored in the medal number counter 311 described below during the deposit acceptance period for accepting the deposit of electronic medals, and sets the electronic medals stored in the medal number counter 311 to an inserted state up to the specified number set for each game state, and performs processing to enable the game start operation on the start lever SL based on the fact that electronic medals equivalent to the specified number have been set to the inserted state.

[0027] In the slot machine 1 of this embodiment, the first pressing of the start lever SL, which is enabled based on the setting of the inserted state of electronic medals equivalent to the specified number, is accepted as a game start operation by the player, which triggers the start of rotation of the left reel R1 to the right reel R3 and also triggers the internal lottery means 120, which will be described later, to execute an internal lottery. The specified number set for each game state will be described later in detail.

[0028] In addition, the deposit acceptance means 105 accepts an input signal output when the settlement button AB is operated during the period from when the electronic medals are set to the inserted state until the start lever SL is operated to cancel the inserted state and adds the same number of electronic medals set to the inserted state to the number of game medals stored in the medal number counter 311, thereby settling the electronic medals set to the inserted state.

[0029] The random number generation means 110 is a means for generating random numbers for lotteries. In this embodiment, the term "random number" includes not only values ​​that are generated randomly in the mathematical sense, but also values ​​that may be generated regularly but whose acquisition timing is irregular, and therefore may function as random numbers.

[0030] The internal lottery means 120 is a means for conducting an internal lottery to determine whether a winning combination will be achieved based on the start signal output when the player performs a start operation on the start lever SL, and performs lottery table selection processing, random number determination processing, lottery flag setting processing, etc.

[0031] In the lottery table selection process, an internal lottery table to be used for the internal lottery is selected based on the current game state from among the multiple internal lottery tables stored in the internal lottery table storage means 192 of the main storage means 190. In each internal lottery table, various combinations such as replays, small combinations, and bonuses, and non-wins (misses) are associated with each of multiple random numbers (for example, 65,536 random numbers from 0 to 65,535).

[0032] In the following description, a bonus means a role that activates a reel or a reel continuous operation device when won, a bonus being activated means that a bonus is won and activates a reel or a reel continuous operation device, and a bonus state means that the reel or reel continuous operation device is activated.

[0033] In the random number determination process, a random number (random number for lottery) generated by the random number generation means 110 is obtained for each game based on the start signal output when the start lever SL is operated to start, and the obtained random number is compared with the internal lottery table selected in the lottery table selection process, and it is determined based on the comparison result whether or not a winning combination has been achieved.

[0034] In the lottery flag setting process, based on the result of the random number determination process, the lottery flag corresponding to the winning combination is set from a non-established state (first flag state, OFF state) to a established state (second flag state, ON state). In the slot machine 1 of this embodiment, when two or more types of combinations are simultaneously won, the lottery flags corresponding to the two or more types of combinations are set to an established state. Note that the slot machine 1 of this embodiment provides a lottery flag (carry-over flag) that can carry over its established state to the next game or thereafter until a prize is won, and a lottery flag (non-carry-over flag) that is reset to an unestablished state without carrying over its established state to the next game or thereafter regardless of whether a prize is won or not. In addition, the lottery flag setting information is stored in the lottery flag storage means 193 of the main storage means 190.

[0035] The reel control means 130 executes reel rotation control, which starts the rotation of the left reels R1 to R3 and controls the rotation pattern of the left reels R1 to R3, based on the player's start operation of the start lever SL and the output of a start signal. Furthermore, when the left reels R1 to R3 are in a steady rotation state at a predetermined speed (e.g., approximately 80 rpm), the reel control means 130 executes control to validate a stop operation by operating the stop buttons B1 to B3 corresponding to each reel. When the stop buttons B1 to B3 are operated to stop and a reel stop signal is output, the reel control means 130 executes control (reel stop control) to stop each of the left reels R1 to R3 corresponding to the stop button B1 to B3 that was operated to stop.

[0036] In the following description, when the reel control means 130 starts the rotation of the left reel R1 to the right reel R3 and the player operates each of the active stop buttons B1 to B3, the first operation will be referred to as the first stop operation, the second operation as the second stop operation, and the third operation as the third stop operation.

[0037] In the slot machine 1 of this embodiment, the left reel R1 to the right reel R3 are stopped by the time a predetermined period of 190 ms (milliseconds, msec) has elapsed since the time when the stop button B1 to B3 is pressed. In the following description, pressing the stop button B1 to B3 is also referred to as an operation. The slot machine 1 may be configured to output a stop signal not only when the stop button B1 to B3 is pressed, but also when, for example, an operation of pressing the stop button B1 to B3 and then releasing the pressed stop button B1 to B3 is performed.

[0038] Here, when the rotating reels are stopped within 190 ms from the time the stop button is pressed, the stop position of each rotating reel is configured to be able to rotate a maximum of four frames from the time the stop button is pressed until the reel stops, depending on the diameter and rotation speed of each reel. Therefore, in the slot machine 1 of this embodiment, for the left reel R1 to the right reel R3, a total of five frames from the frame displayed on the pay line L1 at the time the stop button is pressed until the reel stops are the range (pull-in range) in which symbols can be pulled onto the pay line L1.

[0039] When executing reel stop control, the reel control means 130 performs a logic calculation process to determine the stop position of the spinning reel based on a predetermined priority through logic calculations including a pull-in process to stop the spinning reel so that a winning combination for which the lottery flag is set to a hit state can be won as much as possible, and a kick-off process to stop the spinning reel so that a winning combination for which the lottery flag is set to a non-hit state cannot be won, and a table reference process to determine the stop position of the spinning reel by referring to a stop control table stored in the reel control data storage means 194 of the main storage means 190, thereby stopping the spinning reel and displaying a pattern on the pay line L1 (hereinafter, stopping the spinning reel by reel stop control and displaying a pattern on the pay line L1 is also referred to as a "stop display").

[0040] In the slot machine 1 of this embodiment, when multiple types of small winning combinations are won in the internal lottery, there are two methods for determining the priority of the candidate stop positions: a method for determining the priority according to the number of symbol combinations that can be displayed on the activated line L1 (number priority control), and a method for determining the priority according to the number of electronic medals to be paid out based on the payout predetermined for the small winning combination (number priority control). However, when the number priority control is executed, if multiple small winning combinations with the same payout are won, the priority of the candidate stop positions that can win each small winning combination is treated as being the same.

[0041] The winning determination means 140 performs a winning determination process to determine whether a winning combination has been achieved based on the stopping patterns of the left reel R1 to the right reel R3. Specifically, by referring to the winning determination table stored in the winning determination table storage means 195 of the main storage means 190, it determines whether the symbol combination displayed on the pay line L1 when all of the left reel R1 to the right reel R3 have stopped corresponds to a winning form of a predetermined winning combination. The winning determination table is prepared so that the presence or absence of a bonus, replay, or small winning combination can be determined (hereinafter referred to as "winning determination") based on the symbol combination displayed on the pay line L1 when each reel has stopped. In the following description, the symbol combination that indicates the winning form of the winning combination (the symbol combination related to the winning combination) will also be referred to as the "winning symbol combination."

[0042] In the slot machine 1 of this embodiment, each process is executed based on the determination result of the winning determination process by the winning determination means 140. As each process executed based on the determination result of the winning combination, for example, when a small combination is won, a process is executed to determine the number of game medals to be paid out of electronic medals by the payout control means 150, when a replay is won, a process is executed to make the payout control means 150 execute the next game without consuming electronic medals, and when a combination that triggers a transition of the game state, such as a bonus, is won, a process is executed to make the game state transition control means 160 transition the game state.

[0043] The payout control means 150 performs a payout process for paying out electronic medals according to the game results. Specifically, when a small winning combination is achieved, the payout number of electronic medals in the game is determined based on the payout amount predetermined for each combination, and the number of game medals corresponding to the determined payout number is added to the medal number counter 311 to virtually pay out the medals.

[0044] Furthermore, when the winning determination means 140 determines that a symbol combination indicating a winning replay among a plurality of types of replay roles described later has been stopped and displayed on the pay line L1, and the replay wins, the payout control means 150 performs a replay process (replay process) to set the machine to a ready state in which the next game can be played without inserting electronic medals. That is, in the slot machine 1 of this embodiment, when a replay wins, an automatic insertion process is performed to automatically insert a specified number of electronic medals without using the electronic medals in the player's possession, and the machine waits for the start operation of the start lever SL to be performed next time, with the same pay line L1 as in the previous game set.

[0045] In addition, in the slot machine 1, during the period from the game in which a replay is won until the start of the next game, i.e., during the period in which a specified number of electronic medals are automatically inserted by the replay process but the game has not started, even if the settlement button AB is operated, the number of game medals equal to the specified number will not be added to the medal number counter 311.

[0046] The game state transition control means 160 performs a process for transitioning game states between multiple game states and a process for activation and termination of bonuses. Here, the transition condition for each game state may be one condition or multiple conditions. When multiple conditions are defined, the game state can be transitioned to another game state based on the fulfillment of any one of the multiple predetermined conditions or the fulfillment of all of the multiple predetermined conditions.

[0047] The AT control means 170 uses data stored in the AT control data storage means 196 to control the transition between an advantageous zone (advantageous period), which is a zone (period) during which control related to instruction functions including auxiliary games that display notifications on the main control display device 10D to assist in winning specific roles, and a normal zone (non-advantageous period), which is a zone (period) during which control related to auxiliary games (control related to instruction functions) based on the results of internal lottery by the internal lottery means 120 cannot be executed, and constitutes an auxiliary game control means that performs control related to the normal zone, advantageous zone, and auxiliary games.

[0048] The AT control data storage means 196 stores data (various flags, counters, etc. that are set to ON or OFF by specified control processing) used in various controls related to multiple types of presentation states, including normal states and AT states, that are executed within the advantageous zone.

[0049] The AT control means 170 sets the presentation state to the AT state (assist time state) under predetermined conditions in the advantageous zone, and displays information (an example of operation instruction information) corresponding to the operation mode of the stop buttons B1 to B3 that makes it possible to win the specific role that has been won on the main control display device 10D consisting of a 7-segment display, thereby performing an operation notification to assist in the winning of the specific role. Furthermore, in the slot machine 1, when the operation notification by the AT control means 170 is executed, the presentation control means 200, which will be described later, executes a navigation presentation in which an indicator corresponding to the correct batting order is displayed on the display device 410. In this way, in the slot machine 1, in the AT state, the operation mode of the stop buttons B1 to B3 is notified by the operation notification and the winning assistance of the navigation presentation, thereby executing an auxiliary game (AT game, notification game) that is advantageous to the player.

[0050] More specifically, when a predetermined termination condition for terminating the advantageous zone, which will be described later, is met, the AT control means 170 executes a predetermined termination process that terminates the advantageous zone and starts the normal zone from the next game, and a predetermined initialization process that initializes information related to the advantageous zone, such as various flags and numerical values ​​set within the advantageous zone.

[0051] The AT control means 170 executes an update process (advantageous zone difference number update process) that cumulatively records in the advantageous zone counter 196a the difference value (difference in number of medals, number of medals won) obtained by subtracting the number of medals paid out from the game that started the advantageous zone by the number of medals inserted. When the AT control means 170 is controlling in the advantageous zone, regardless of the game state, it executes advantageous zone difference number update process that cumulatively updates the value equivalent to the difference in number of medals to the stored value of the advantageous zone counter 196a.

[0052] Furthermore, in the advantageous zone difference number update process, when the number of medals paid out in the game is less than the specified number and the stored value of the advantageous zone counter 196a is subtracted, the AT control means 170 also sets the subtracted result in the advantageous zone counter 196a even if the stored value of the advantageous zone counter 196a becomes less than the value "0." In other words, the AT control means 170 is configured to be able to set a negative value in the advantageous zone counter 196a.

[0053] When more than 2400 medals are won in the advantageous zone, that is, when the value stored in the advantageous zone counter 196a exceeds the value "2400," the AT control means 170 determines that a specific termination condition has been met as a predetermined termination condition for terminating the advantageous zone, and executes a predetermined termination process that terminates the advantageous zone and starts the normal zone from the next game. For this reason, in the slot machine 1, for example, if the value stored in the advantageous zone counter 196a is a negative value of "-900" before the transition to a presentation state in which medals can be won, a total of 3301 medals can be won in the presentation state in which medals can be won: 900 medals until the value stored in the advantageous zone counter 196a becomes the value "0," and 2401 medals until the value stored in the advantageous zone counter 196a becomes the value "2401" or more.

[0054] In a predetermined initialization process, the AT control means 170 initializes all information used in various control processes in the advantageous zone, such as each flag set to ON in the advantageous zone and values ​​set in the advantageous zone. Note that the AT control means 170 can also end the advantageous zone when a predetermined end condition (normal end condition) other than the specific end condition is met, and also executes the predetermined initialization process and predetermined end process when the normal end condition is met. Details of the normal end condition set by the AT control means 170 in this embodiment will be described later.

[0055] The complete control means 180 controls the activation of a complete function, which is a function that stops the slot machine 1 when the cumulative number of medals won since the slot machine 1 was powered on reaches a predetermined value (for example, 19,000 medals). The complete control means 180 executes an update process (complete earned number update process) that cumulatively records the difference value (number of medals difference, number of medals won) obtained by subtracting the number of medals paid out in each game by the number of medals inserted after the slot machine 1 is powered on in the earned medal number counter 197a of the complete storage means 197. Note that the complete control means 180 does not update the stored value of the earned medal number counter 197a when a replay wins.

[0056] In a complete winning number update process that updates the stored value of the earned medal counter 197a, if the stored value of the earned medal counter 197a becomes less than the value "0" when the stored value of the earned medal counter 197a is subtracted because the number of medals paid out in the game is less than the specified number, the complete control means 180 sets the stored value of the earned medal counter 197a to the value "0." This allows the complete control means 180 to fix the value when the stored value of the earned medal counter 197a reaches its lowest point to the value "0." Therefore, in the control process that uses the stored value of the earned medal counter 197a, it is not necessary to vary the value that serves as the judgment threshold depending on the specific numerical value at the lowest point, and the load of the control process that uses the stored value of the earned medal counter 197a can be reduced.

[0057] The complete control means 180 determines that the conditions for activating the complete function are met when the number of game medals acquired from the lowest point of the number of electronic medals paid out after the slot machine 1 is powered on reaches 19,000, that is, when the stored value of the medal acquisition number counter 197a reaches the value "19,000."

[0058] When none of the Regular Bonus (RB) as a first type special feature, the Regular Big Bonus (RBB) as a feature continuous operation device related to the first type special feature, and the Challenge Big Bonus (CBB) as a feature continuous operation device related to the second type special feature is operating, the complete control means 180 activates the complete function after the stop buttons B1 to B3 are operated to stop and the left reel R1 to right reel R3 are stopped in a game in which the conditions for activating the complete function are met, based on the establishment of the conditions for activating the complete function.

[0059] On the other hand, when any of RB, RBB or CBB is activated, the complete control means 180 activates the complete function after the stop buttons B1 to B3 are operated to stop and the left reel R1 to right reel R3 stop in a game in which the activated RB, RBB or CBB has ended.

[0060] When the complete function is activated, the complete control means 180 sets the complete function activation flag stored in the complete flag storage means 197b of the complete storage means 197 to the ON state. When the complete function activation flag is set to the ON state, the slot machine 1 enters a play-stop state, and no further play can be performed until the complete function activation flag is set to the OFF state. The complete function activation flag that has been set to the ON state is reset to the OFF state by opening the upper front door UD of the slot machine 1 and operating the setting change button BS provided inside. With this configuration, when the complete function is activated, the slot machine 1 is configured so that the complete function cannot be released by an operation by the player.

[0061] The sub-control CPU 21 functions as the performance control means 200. Each means constituting the sub-control CPU 21 reads out and executes each control program stored in advance in the sub-storage means 210 when executing each control process.

[0062] The effect control means 200 controls effects related to the game, such as image and video effects using the display device 410 and sound effects using the sound device 420, based on the effect data stored in the effect control data storage means 211 of the sub-storage means 210. Specifically, when a player operates each component of the slot machine 1, such as the max bet button MB, the start lever SL, the stop buttons B1 to B3, or the count button KB, or when a game event such as a change in the game state occurs, the effect control means 200 controls the execution of effects to liven up the game, assist the game, and notify the player that an operation has been performed, by executing effects such as lighting or flashing of lamps and LEDs and sound output from the sound device 420. In addition, the effect control means 200 causes each component of the effect device 400 to execute effects based on each effect state.

[0063] The performance control means 200 superimposes the images drawn on a plurality of layers into a single image in the frame buffer 213 provided in the sub-storage means 210, and displays the superimposed image in the display area 410a of the display device 410. When drawing an image in the frame buffer 213, the performance control means 200 draws the images in the frame buffer 213 in order from the image drawn on the lower layer, so that the image drawn on the higher layer is displayed in the display area 410a in priority to the image drawn on the lower layer.

[0064] The medal count control CPU 31 functions as medal count control means 300. Each means constituting the medal count control CPU 31 reads out and executes each control program stored in advance in the medal count storage means 310 when executing each control process.

[0065] The medal count control means 300 mainly updates (adds or subtracts) the number of game medals stored (held) in the medal count counter 311 in response to commands received from the main control board 10, notifications received from the dedicated unit SU, or operation of the count button KB incorporating the count switch 126. The medal count control means 300 also displays the number of game medals updated in this way on the game medal number display device MD.

[0066] Specifically, when the counting button KB is operated while play is possible, the medal count control means 300 transmits a value corresponding to the number of game medals stored in the medal count counter 311 to the dedicated unit SU via the lending device connection terminal board 40, and subtracts the number of medals corresponding to the transmitted value from the medal count counter 311. Here, "while play is possible" means a state in which the gaming machine and the dedicated unit SU are electrically connected, both the gaming machine and the dedicated unit SU are powered on, neither the gaming machine nor the dedicated unit SU is undergoing maintenance, and no errors that prevent play from occurring. Furthermore, when the slot machine 1 is not connected to the dedicated unit SU, the slot machine 1 controls the counting button KB so that the stored value of the medal count counter 311 is not decremented by operation of the counting button KB, thereby preventing a situation in which a signal is not sent to the dedicated unit SU even though the stored value of the medal count counter 311 has been decremented.

[0067] If the count button KB is pressed for less than 500 ms, the medal count control means 300 transmits the value "1" corresponding to 1 medal to the dedicated unit SU via the lending device connection terminal board 40, and decrements the stored value of the medal count counter 311 by the value "1." Also, if the count button KB is pressed for 500 ms or more, the medal count control means 300 transmits the value "50" corresponding to 50 medals to the dedicated unit SU via the lending device connection terminal board 40 at the timing of counting after 500 ms has elapsed, and decrements the stored value of the medal count counter 311 by the value "50." Thereafter, every time 300 ms has elapsed while the count button KB is pressed, the medal count control means 300 transmits the value "50" corresponding to 50 medals to the dedicated unit SU via the lending device connection terminal board 40, and decrements the stored value of the medal count counter 311 by the value "50." Furthermore, if the stored value of the medal count counter 311 is less than the value "50" when 500 ms or more has elapsed since the counting button KB was pressed, the medal count control means 300 transmits a value corresponding to the stored value of the medal count counter 311 to the dedicated unit SU via the lending device connection terminal board 40, and subtracts the value corresponding to the stored value from the stored value of the medal count counter 311, thereby setting the stored value of the medal count counter 311 to the value "0".

[0068] When the stored value of the medal count counter 311 becomes equal to or greater than the value "16369," the medal count control means 300 determines that a medal overflow has occurred, in which the number of game medals stored exceeds 16368, which is the limit set for storage in the slot machine 1. In the slot machine 1, a medal overflow error occurs based on the determination that a medal overflow has occurred, and when the count button KB is operated to count the number of game medals stored in the medal count counter 311 and the stored value of the medal count counter 311 becomes equal to or less than the value "16368," the medal overflow error is canceled.

[0069] When the power is turned on with a medal count clear button CL provided inside the gaming machine pressed, the medal count control means 300 initializes the medal count counter 311 and clears (initializes) the medal count by setting the stored value of the medal count counter 311 to the value "0." This allows the slot machine 1 to initialize, when the power is turned on, the information on the number of medals remaining in the medal count counter 311 before the power was turned off.

[0070] When the power is turned on with a medal count clear button CL provided inside the gaming machine pressed, the medal count control means 300 initializes the medal count counter 311 and clears (initializes) the medal count by setting the stored value of the medal count counter 311 to the value "0." This allows the slot machine 1 to initialize, when the power is turned on, the information on the number of medals remaining in the medal count counter 311 before the power was turned off.

[0071] 2. Configuration of the gaming machine in this embodiment Next, with reference to FIGS. 2 to 16, details of each component included in the slot machine 1 of this embodiment will be described.

[0072] <Control of the specified number by the input receiving means> In the slot machine 1 of this embodiment, during a deposit acceptance period in which the deposit acceptance means 105 accepts the deposit of medals, when the max bet button MB is operated (bet operation) with the number of game medals stored in the medal number counter 311 being equal to or greater than the specified number, input signals equal in number to the specified number set for each game state are output. Each time an input signal is input, the deposit acceptance means 105 adds a value "1" equivalent to one medal to the deposit number storage means 198 of the main storage means 190, and continues to add values ​​to the deposit number storage means 198 up to the specified number set for each game state.

[0073] In the slot machine 1 of this embodiment, the specified number for the non-RT state and the RBB internal state is set to three (first specified number), and for the RBB state, the specified number is set to two (second specified number).

[0074] In other words, when the gaming state is a non-RT state or an RBB internal state, the input acceptance means 105 stores a value "3" in the input number storage means 198 based on the input signal being input three times by operating the max bet button MB when three or more gaming medals are stored in the medal count counter 311. Also, when the gaming state is an RBB state, the input acceptance means 105 stores a value "2" in the input number storage means 198 based on the input signal being input two times by operating the max bet button MB when two or more gaming medals are stored in the medal count counter 311.

[0075] <Winning areas subject to internal lottery> 3 is a diagram showing the winning areas that are the subject of the internal lottery in the slot machine 1 of this embodiment, and the winning numbers and winning combinations that are associated with each winning area. Note that the slot machine 1 of this embodiment has an RBB as a bonus, which is a device for continuously operating a special bonus related to a first-class special bonus.

[0076] As shown in FIG. 3, in the slot machine 1 of this embodiment, the winning areas that are subject to internal lottery include the winning area "bonus small / medium role 1", the winning area "bonus small / medium role 2", the winning area "batting order bell 1A" to the winning area "batting order bell 4A", the winning area "batting order bell 1B" to the winning area "batting order bell 4B", the winning area "batting order bell 1C" to the winning area "batting order bell 4C", the winning area "batting order bell 1D" to the winning area "batting order bell 4D", the winning area "rare role", the winning area "replay 1", the winning area "replay 2", the winning area "RBB&3-piece role 1" to the winning area "RBB&3-piece role 8", the winning area "RBB&1-piece role 1" to the winning area "RBB&1-piece role 16" and the winning area "RBB", and the winning numbers 1 to 46 are associated with them, respectively. In addition, in the slot machine 1, the winning number 0 is associated with a non-winning result (loss) as a result of the internal lottery.

[0077] Here, "batting order" refers to the order in which the stop buttons B1 to B3 are operated. In the following description, the timing at which the stop buttons B1 to B3 are operated will also be referred to as "operation timing."

[0078] In the slot machine 1 of this embodiment, the batting order, which is the order in which the three stop buttons B1 to B3 are operated, is comprised of six types of batting orders, batting order 1 to batting order 6. Batting order 1 is a batting order in which the stop operation is performed in the order of stop button B1 → stop button B2 → stop button B3, which is called a "sequential pressing" batting order. Batting order 2 is a batting order in which the stop operation is performed in the order of stop button B1 → stop button B3 → stop button B2, which is called a "scissors hitting" batting order. Batting order 3 is a batting order in which the stop operation is performed in the order of stop button B2 → stop button B1 → stop button B3. Batting order 4 is a batting order in which the stop operation is performed in the order of stop button B2 → stop button B3 → stop button B1. Batting order 5 is a batting order in which the stop operation is performed in the order of stop button B3 → stop button B1 → stop button B2. Batting order 6 is a batting order called reverse pressing, in which the stop operation is executed in the order of stop button B3 → stop button B2 → stop button B1.

[0079] In the random number determination process, the internal lottery means 120 determines whether each winning area is a winner in order from the winning area associated with winning number 46 to the non-winning area associated with winning number 0.

[0080] The slot machine 1 of this embodiment has small role 1 to small role 49 as small roles that can be won if the internal lottery is won, and has Replay 1 and Replay 2 as replays that can be won in the internal lottery. Each small role and each replay is associated with each winning area in the combination shown in FIG. 3. Also, as shown in FIG. 3, in the slot machine 1, winning areas including bonuses and small roles are set from "RBB&3 role 1" to "RBB&3 role 8", and winning areas "RBB&1 role 1" to "RBB&1 role 16", and the winning area "RBB" is set as a winning area including only bonuses.

[0081] In the slot machine 1, the winning probability for the winning area "Replay 2" is set lower than that for the winning areas of other replays. Also, in the slot machine 1, the winning probability for the winning area "Rare Role" is set lower than that for each winning area including minor roles, such as winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A," winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B," winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C," winning area "Batting Order Bell 1D" to winning area "Batting Order Bell 4D," winning area "RBB&3-coin role 1" to winning area "RBB&3-coin role 8," and winning area "RBB&1-coin role 1" to winning area "RBB&1-coin role 16."

[0082] Here, in the slot machine 1 of this embodiment, the role associated with the carryover flag is RBB, and the small role and replay are associated with the non-carryover flag. That is, in the lottery flag setting process, when a winning area including RBB is won in the internal lottery, a process is performed to carry over the established state of the lottery flag of the winning RBB until the RBB is won. At this time, the internal lottery means 120 performs an internal lottery to determine whether the small role and replay will be won or not, even in a game in which the established state of the lottery flag of RBB is carried over. That is, in the lottery flag setting process, when a small role or replay is won in a game in which the established state of the lottery flag of RBB is carried over, lottery flags corresponding to two or more roles consisting of the lottery flag of the already-won RBB and the lottery flag of the small role or replay won in the internal lottery are set to an established state.

[0083] <Internal lottery table> The slot machine 1 of this embodiment stores, as internal lottery tables that are lottery tables used in the internal lottery by the internal lottery means 120, an internal lottery table used in the non-RT state (normal state) (hereinafter referred to as internal lottery table A), an internal lottery table used in the RBB internal state (internal state) (hereinafter referred to as internal lottery table B), and an internal lottery table used in the RBB state (hereinafter referred to as internal lottery table C) in the internal lottery table storage means 192. In each of the internal lottery tables A to C, a lottery value number is associated with each winning area that is the subject of the lottery.

[0084] In the slot machine 1 of this embodiment, the internal lottery table A is configured so that 65,536 lottery values ​​correspond to any of the winning areas "Batting Order Bell 1A" to "Batting Order Bell 4A", winning area "Batting Order Bell 1B" to "Batting Order Bell 4B", winning area "Batting Order Bell 1C" to "Batting Order Bell 4C", winning area "Batting Order Bell 1D" to "Batting Order Bell 4D", winning area "Rare Role", winning area "Replay 1", winning area "Replay 2", winning area "RBB&3-Coin Role 1" to winning area "RBB&3-Coin Role 8", winning area "RBB&1-Coin Role 1" to winning area "RBB&1-Coin Role 16", and winning area "RBB", and is configured to win any of the small role, replay, or bonus in the internal lottery.

[0085] In addition, the internal lottery table B is configured so that the 65,536 lottery values ​​correspond to any of the winning areas "Batting Order Bell 1A" to "Batting Order Bell 4A", winning area "Batting Order Bell 1B" to "Batting Order Bell 4B", winning area "Batting Order Bell 1C" to "Batting Order Bell 4C", winning area "Batting Order Bell 1D" to "Batting Order Bell 4D", winning area "Rare Role", winning area "Replay 1", winning area "Replay 2", winning area "RBB&3-coin Role 1" to winning area "RBB&3-coin Role 8", and winning area "RBB&1-coin Role 1" to winning area "RBB&1-coin Role 16", and is configured so that the internal lottery will result in a win of either a small role, replay, or bonus.

[0086] In the internal lottery table A and the internal lottery table B, the number of lottery values ​​associated with the winning area "RBB" in the internal lottery table A is associated with the winning area "Replay 2" in the internal lottery table B. The winning probability of each winning area other than the winning area "Replay 2" and the winning area "RBB" in the internal lottery table A is the same as the winning probability of each winning area other than the winning area "Replay 2" in the internal lottery table B. Specifically, for example, the winning probability of the winning area "Batting Order Bell 1A" to the winning area "Batting Order Bell 4A" in the internal lottery table A is the same as the winning probability of the winning area "Batting Order Bell 1A" to the winning area "Batting Order Bell 4A" in the internal lottery table B.

[0087] The internal lottery table C is configured so that 65,536 lottery value numbers correspond to either the winning area "bonus small / medium role 1" or the winning area "bonus small / medium role 2", and is configured to win a small role in the internal lottery. Also, in the internal lottery using the internal lottery table C, it is configured so that each of the small roles 1 to 49 is won with a higher probability than the winning probability of each of the small roles 1 to 49 in the internal lottery using the internal lottery table A or the internal lottery table B.

[0088] Due to this configuration, the slot machine 1 of this embodiment is configured so that there will be no loss (miss) in the internal lottery in any of the gaming states, namely the non-RT state, the RBB internal state, and the RBB state.

[0089] <Random number determination process> In the random number determination process, the internal lottery means 120 of this embodiment sequentially subtracts the random number obtained from the random number generation means 110 by the lottery value numbers associated with each winning area in the internal lottery table obtained from the internal lottery table storage means 192, and when the result of the subtraction is a negative value, it determines that the winning area corresponding to the subtracted lottery value number has been won. Also, when the result of the subtraction is a positive value after completing the subtraction of all the lottery value numbers stored in the internal lottery table, it determines that no winning combination has been won, that is, that the player has not won. <Bonus winning determination process> As described above, in the internal lottery table B of this embodiment, in the RBB internal state, lottery values ​​are set in the winning area "RBB & 3-piece role 1" to the winning area "RBB & 3-piece role 8", and in the winning area "RBB & 1-piece role 1" to the winning area "RBB & 1-piece role 16". In the internal lottery when the gaming state is in the RBB internal state, there is a possibility that an RBB will be won again when an RBB has already been set to a formed state. Therefore, the internal lottery means 120 is configured to execute a bonus win determination process to determine whether or not the winning area whose win or loss is determined by the random number determination process is a winning area including a bonus, in order not to set the newly won RBB to a formed state.

[0090] In the bonus win determination process, when the random number determination process determines that the winning area including the bonus is the target for determining whether it is a win or a loss, if the winning area including the bonus is won and the gaming state is the RBB internal state, the internal lottery means 120 executes a process to skip the process of setting the bonus to the established state. In this way, the slot machine 1 prevents a new RBB from being set to the established state when an RBB is already set to the established state.

[0091] <Arrangement of designs> FIG. 4 is a diagram showing the symbols arranged on the periphery of the left reel R1 to the right reel R3 in the slot machine 1 of this embodiment. As shown in FIG. 4, 20 symbols are arranged on each of the left reel R1 to the right reel R3 in this embodiment. Seven types of symbols are arranged on each of the left reel R1 to the right reel R3: a red 7 symbol "RED 7," a white 7 symbol "WHITE 7," a bell symbol "BL," a replay "RP," a blank A symbol "BKA," and a blank C symbol "BKC." A cherry A symbol "CHA" is arranged on the periphery of the left reel R1, a cherry B symbol "CHB" is arranged on the periphery of the center reel R2, and a cherry C symbol "CHC" is arranged on the periphery of the right reel R3.

[0092] In this embodiment, although the cherry A design "CHA", the cherry B design "CHB", and the cherry C design "CHC" are configured as different types of designs, they are each composed of a design with a bell motif, and therefore have common characteristics and are configured as designs with approximately similar designs.

[0093] <Reel control means> In the slot machine 1 of this embodiment, in any game state, the priority order of the winning combinations to be stopped on the pay line L1 in the reel stop control is determined in the order of "replay > small combination > bonus." In other words, when a bonus and a small combination or a bonus and a replay are both won, the reel control means 130 executes stop control to give priority to the bonus and win the small combination or replay.

[0094] Furthermore, as described above, the reel control means 130 is configured to be able to rotate the reels a maximum of four frames from the time the stop button is pressed until the reels stop, and is therefore configured to be able to stop and display the symbols arranged on the left reel R1 to the right reel R3 that are arranged at intervals of four frames or less on the activated line L1 regardless of the timing of operation of the stop buttons B1 to B3.

[0095] Specifically, the reel control means 130 is configured to be able to stop the replay symbol "RP", bell symbol "BL", blank A symbol "BKA" on the left reel R1 to right reel R3, cherry A symbol "CHA" on the left reel R1, cherry B symbol "CHB" on the center reel R2, and cherry C symbol "CHC" on the right reel R3 on the activated line L1, regardless of the operation timing of stop buttons B1 to B3.

[0096] Furthermore, the reel control means 130 is capable of stopping symbols that are not the same as each other as long as they are arranged at intervals of four frames or less. For example, if any of the white 7 symbol "White 7" arranged at stop number 2 on the left reel R1, the blank B symbol "BKB" arranged at stop number 7, the red 7 symbol "Red 7" arranged at stop number 12, or the blank C symbol "BKC" arranged at stop number 17 can be stopped on the active line L1, the reel control means 130 is configured to be able to stop the red 7 symbol "Red 7", the white 7 symbol "White 7", the blank B symbol "BKB" or the blank C symbol "BKC" regardless of the timing of operation of the stop button B1.

[0097] <Details of small prizes> 5 to 7 are diagrams showing winning symbol combinations of small winning symbols 1 to 49 provided in the slot machine 1, payouts for small winning symbols 1 to 49, and the numbers of winning symbol combinations of small winning symbols 1 to 49.

[0098] Here, the number of winning symbol combinations refers to the number of symbol combinations that correspond to winning symbol combinations among the symbol combinations that can be configured from the symbols arranged on each of the left reel R1 to the right reel R3. For example, if the winning symbol combination is a small win 1 consisting of "CHA-RP-BKA", the cherry A symbol "CHA" arranged at stop number 4 on the left reel R1, the replay symbol "RP" arranged at stop number 0 on the middle reel R2, and the right reel The symbol combination "CHA-RP-BKA" consisting of the blank A symbol "BKA" arranged at stop number 0 on R3, and the symbol combination "CHA-RP-BKA" consisting of the cherry A symbol "CHA" arranged at stop number 9 on left reel R1, the replay symbol "RP" arranged at stop number 0 on center reel R2, and the blank A symbol "BKA" arranged at stop number 0 on right reel R3 are counted as separate winning symbol combinations.

[0099] As shown in Figures 5 to 7, in the slot machine 1 of this embodiment, the payout for each minor role is set when a game is started by inserting three medals as the first specified number (three medal bet) and when a game is started by inserting two medals as the first specified number (two medal bet).

[0100] Of the small winning combinations 1 to 49 shown in Figures 5 to 7, for example, small winning combinations such as small winning combination 1 consisting of "CHA-RP-BKA", in which the patterns on the left reel R1 to right reel R3 that make up the winning combination are arranged at intervals of no more than four frames on each reel, are configured to be stopped and displayed on the valid line L1 regardless of the timing of operation of stop buttons B1 to B3 when reel stop control is executed to enable the small winning combination to be stopped and displayed on the valid line L1.

[0101] On the other hand, among the small winning combinations 1 to 49, for example, small winning combination 10 is composed of "RP-BKA-Red 7" and the timing of operating the stop button B3 to stop and display the Red 7 symbol "Red 7" on the right reel R3 on the valid line L1 is limited. In the case of small winning combinations where the winning symbol combination is composed of symbols arranged at intervals wider than four frames on at least one reel among the symbols on the left reel R1 to the right reel R3 that make up the winning symbol combination, if the stop button is operated at a timing different from the timing that allows the symbol to be stopped and displayed on the valid line L1, the winning symbol cannot be won.

[0102] As shown in Fig. 5, the payouts for minor winning combinations 1 and 2 when a three-coin bet game is executed are set to 15, which is more than the first specified number. Also, the payouts for minor winning combinations 3 to 6 when a three-coin bet game is executed are set to 3, which is the same as the first specified number. Also, the payouts for minor winning combinations 1 to 6 when a two-coin bet game is executed are set to 1, which is less than the second specified number, and the payouts for when a three-coin bet game is executed and when a two-coin bet game is executed are set to different payouts.

[0103] Also, as shown in Figures 5 to 7, minor winnings 7 to 49 have the same payout when a game is played with a bet of three coins as when a game is played with a bet of two coins, and are set to one coin, which is less than the second specified number.

[0104] <Game state transition control means> FIG. 8(A) is a state transition diagram showing game states to which transition can be made from each game state in the control relating to transition of game states executed by the game state transition control means 160 of this embodiment.

[0105] As shown in Figure 8 (A), the non-RT state is a gaming state (initial gaming state, normal gaming state) that corresponds to the initial state among multiple gaming states, and is a non-bonus state in which a bonus is not activated or established. In the non-RT state, the gaming state transition control means 160 causes the internal lottery means 120 to execute an internal lottery using the internal lottery table A in which the winning probability of a replay is set to 8978 / 65536 (approximately 1 / 7.3). In the slot machine 1, when the gaming state is the non-RT state, a first specified number (3 medals) of medals are set to an inserted state, so that a game can be started.

[0106] The RBB internal state is a game state to which the slot machine 1 transitions when a winning area in the non-RT state is selected from the winning areas "RBB & 3-coin role 1" to "RBB & 3-coin role 8," "RBB & 1-coin role 1" to "RBB & 1-coin role 16," or "RBB," and the RBB is set to an established state. In the RBB internal state, the game state transition control means 160 causes the internal lottery means 120 to execute an internal lottery using internal lottery table B, in which the winning probability of a replay is set to 8982 / 65536 (approximately 1 / 7.3). In the slot machine 1, when the game state is the RBB internal state, a first specified number (3 medals) of medals are inserted, and the slot machine 1 is configured to be able to start playing.

[0107] The RBB state is a gaming state to which the game is transitioned when the RBB wins and the RBB is activated. In the RBB state, the gaming state transition control means 160 determines that the RBB termination condition is met when more than a predetermined payout number (e.g., 12 medals) have been paid out, terminates the operation of the RBB, and transitions the gaming state to a non-RT state. In the RBB state, the gaming state transition control means 160 causes the internal lottery means 120 to execute an internal lottery using the internal lottery table C. In the slot machine 1, when the gaming state is the RBB state, the slot machine 1 is configured so that a game can be started by setting the second specified number (2 medals) of medals to the inserted state. Details of the gameplay in the RBB state will be described later.

[0108] <AT control means> FIG. 8(B) is a state transition diagram showing details of a normal section and a favorable section controlled by the AT control means 170 of the present embodiment, and a production state controlled during the favorable section.

[0109] As described above, the normal section is a period in which control related to the auxiliary game based on the result of the internal lottery by the internal lottery means 120 is not executed. The AT control means 170 executes a favorable section lottery, which is a lottery for determining whether to end the normal section and start the favorable section based on the winning area won in the internal lottery by the internal lottery means 120 in the game within the normal section.

[0110] In the favorable section lottery, the AT control means 170 first obtains a favorable section transition lottery table, which is a data table in which "start of favorable section" and "loss (non-winning)" are associated with each of a plurality of random numbers, from the AT control data storage means 196. Then, the AT control means 170 obtains a random number from the random number generation means 110, compares the obtained random number with the favorable section transition lottery table, and determines whether to start the favorable section based on the comparison result.

[0111] The AT control means 170 executes the favorable section lottery so that the probability obtained by multiplying the winning probability of the winning area won in the internal lottery by the winning probability of "start of favorable section" in the favorable section lottery is 1 / 17500 or more.

[0112] The AT control means 170 of this embodiment is configured to execute a lottery for an advantageous zone when the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A", the winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B", the winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C", the winning area "Batting Order Bell 1D" to winning area "Batting Order Bell 4D", the winning area "Rare Role", the winning area "Replay 1", the winning area "RBB&3-Coin Role 1" to winning area "RBB&3-Coin Role 8", the winning area "RBB&1-Coin Role 1" to winning area "RBB&1-Coin Role 16" is won in the internal lottery in the non-RT state and the RBB internal state, and when the winning area "RBB" is won in the internal lottery in the non-RT state, and not to execute a lottery for an advantageous zone when another winning area is won. In addition, the AT control means 170 executes a lottery for an advantageous zone with a high probability of about 1 / 1.5, which results in winning the "start of an advantageous zone".

[0113] In the advantageous zone, the AT control means 170 has three states (presentation states) related to the instruction function: a normal state, a CZ state, and an AT state. In the normal state, it is configured not to execute assistance for winning minor feature 1 when the winning area is won from "Batting Order Bell 1A" to "Batting Order Bell 4A", from "Batting Order Bell 1B" to "Batting Order Bell 4B", from "Batting Order Bell 1C" to "Batting Order Bell 4C", or from "Batting Order Bell 1D" to "Batting Order Bell 4D". In the CZ state and the AT state, it is configured to execute assistance for winning minor feature 1 and minor feature 2 when the winning area is won from "Batting Order Bell 1A" to "Batting Order Bell 4A", from "Batting Order Bell 1B" to "Batting Order Bell 4B", from "Batting Order Bell 1C" to "Batting Order Bell 4C", or from "Batting Order Bell 1D" to "Batting Order Bell 4D". Furthermore, the slot machine 1 of this embodiment is configured so that the proportion of players staying in the advantageous zone during the entire game can be 70% or more.

[0114] The normal state is a presentation state (normal presentation state) that corresponds to the normal state among multiple types of presentation states, and is set when there is no transition to another presentation state. When the presentation state transitions to the normal state, the AT control means 170 performs an incremental update to add a value "1" corresponding to one game to the stored value of a normal game number counter (not shown), which counts the number of games played in the normal state, each time a game is played. When the stored value of the normal game number counter reaches the value "700", the AT control means 170 determines that the transition condition to the CZ state (CZ transition condition) has been met, and transitions the presentation state from the normal state to the CZ state.

[0115] The AT control means 170 is configured to execute a CZ lottery to determine whether or not to transition to the CZ state in a game in which a winning area that does not include an RBB is won in an internal lottery in the normal state.

[0116] In addition, when the AT control means 170 wins the winning area "rare role" in the internal lottery, it executes a normal AT lottery to determine whether or not to transition to the AT state, and when it wins "transition to AT state," it determines that the transition condition to the AT state (AT transition condition) has been met, and transitions from the normal state to the AT state.

[0117] The CZ state is configured to be able to transition to the AT state with a higher probability than the normal state when control for determining whether to transition the presentation state to the AT state is executed as a control related to auxiliary games, and is a presentation state that is more advantageous to the player than the normal state. At the start of the CZ state, the AT control means 170 sets a value corresponding to a predetermined number of games (for example, 10 games) to the CZ game number counter (not shown) of the AT control data storage means 196, and executes a decrement update each time a game is executed, subtracting the value stored in the CZ game number counter by the value "1" corresponding to one game.

[0118] The AT control means 170 is configured to execute a CZ AT lottery to determine whether or not to transition to the AT state during each game in the CZ state. If the "transition to the AT state" is selected in the CZ AT lottery, the AT control means 170 transitions the presentation state from the CZ state to the AT state after 10 games have been played since the start of the CZ state.

[0119] The AT control means 170 executes a CZ set number addition lottery to determine whether or not to add (add) the number of times one set of AT state is executed for the AT state to which the player is transitioned from the CZ state during play until the CZ state ends after winning the "transition to AT state" in the CZ AT lottery.

[0120] On the other hand, if 10 games are played in the CZ state without winning the "transition to AT state" in the AT lottery during the CZ, the AT control means 170 ends the CZ state and transitions the presentation state to the normal state.

[0121] The AT control means 170 is configured to execute lotteries relating to auxiliary games executed in the CZ state (AT lottery during CZ, set number addition lottery during CZ) regardless of the result of the internal lottery. Also, the AT control means 170 is configured so that, for lotteries relating to auxiliary games executed in the CZ state, if the winning area "rare role" is won in the internal lottery, the probability of "not winning (missing)" is lower than when other winning areas are won, and the probability of an outcome advantageous to the player ("transition to AT state" in the case of an AT lottery during CZ) is higher.

[0122] The AT state is a more advantageous presentation state for players than the normal state, as assistance is provided for winning minor prizes 1 and 2 when winning areas "Batting Order Bell 1A" to "Batting Order Bell 4A", "Batting Order Bell 1B" to "Batting Order Bell 4B", "Batting Order Bell 1C" to "Batting Order Bell 4C", and "Batting Order Bell 1D" to "Batting Order Bell 4D".

[0123] At the start of the AT state, the AT control means 170 sets an initial value (50 games) corresponding to a predetermined number of games in the AT game number counter (not shown) of the AT control data storage means 196, and performs a decrement update each time a game is played, subtracting the stored value of the AT game number counter by the value "1" corresponding to one game.

[0124] In addition, when the internal lottery by the internal lottery means 120 wins the winning area ``rare role,'' the AT control means 170 executes an add-on lottery to determine whether to add (add) the period during which the AT state continues by determining whether to add a value determined by lottery to the stored value of the AT game number counter, and is configured to execute an add-on process to add the determined value to the AT game number counter if the value determined by the add-on lottery is 1 or greater.

[0125] When the stored value of the AT game number counter becomes "0" due to the decrement update performed each time a game is played in the AT state, the AT control means 170 determines that the termination condition of the AT state (AT termination condition) has been met, terminates the AT state, and determines that the normal termination condition among the termination conditions of the advantageous zone has been met, and executes a predetermined initialization process which is a process of initializing information related to the advantageous zone, and a predetermined termination process which terminates the advantageous zone and starts the normal zone from the next game.

[0126] In addition, if the stored value of the advantageous zone counter 196a exceeds the value "2400" in the AT state, the AT control means 170 determines that the AT termination condition has been met, terminates the AT state, and determines that a specific termination condition among the termination conditions for the advantageous zone has been met, and executes a predetermined initialization process which is a process for initializing information related to the advantageous zone, and a predetermined termination process which ends the advantageous zone and starts the normal zone from the next game.

[0127] As shown in Figure 8 (B), the AT control means 170 is configured to set the presentation state at the start of the advantageous zone to the CZ state when the "start of advantageous zone" is won in the advantageous zone lottery in the normal zone and the advantageous zone starts. Also, as described above, the AT control means 170 is configured to end the advantageous zone and start the normal zone when the AT state ends.

[0128] With this configuration, the slot machine 1 of this embodiment is configured so that the CZ state begins when the AT state ends and the normal zone transitions to the advantageous zone, so that the probability of transitioning back to the AT state is higher than when the normal state is set at the start of the normal zone. As a result, once the AT state begins, the slot machine 1 of this embodiment can start the AT state again via the normal zone and CZ state, so that electronic medals can be acquired through multiple AT states, increasing the player's interest in the game.

[0129] 3. Playability in each game state Next, the gameplay in each game state of the slot machine 1 of this embodiment will be described.

[0130] <Game results in each game state> FIG. 9 is a diagram showing game results for each operation mode of the stop buttons B1 to B3 when winning in the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A", the winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B", the winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C", and the winning area "Batting Order Bell 1D" to winning area "Batting Order Bell 4D" in the non-RT state. FIG. 10 is a diagram showing game results for each operation mode of the stop buttons B1 to B3 when winning in the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A", the winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B", and the winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C" in the RBB internal state. 11 is a diagram showing the game results for each operation mode of stop button B1 to stop button B3 when winning the winning area "Rare Role", winning area "RBB&3 Coin Role 1" to winning area "RBB&3 Coin Role 8", and winning area "RBB&1 Coin Role 1" to winning area "RBB&1 Coin Role 16" in the non-RT state and the RBB inside state; and FIG. 12 is a diagram showing the game results for each operation mode of stop button B1 to stop button B3 in the RBB state.

[0131] As shown in Figure 9, in the slot machine 1, when the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A" or the winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B" is won in the non-RT state, the minor winning combination with the payout set to 1 coin in a 3-coin bet game can be won with the probability (winning probability) shown in Figure 9, regardless of the operation mode of the stop buttons B1 to B3.

[0132] A specific explanation will be given using the winning area "Batting Order Bell 1A." In the slot machine 1, when the winning area "Batting Order Bell 1A" is won in the internal lottery in the non-RT state and the stop button B1 is operated to perform the first stop, if the replay symbol "RP" is stopped and displayed on the activated line L1, the four symbol combinations of the winning symbol combination "RP-BKA-BKA" of the small win 9 shown in FIG. 5, the winning symbol combination "RP-BKA-Red 7" of the small win 10, the winning symbol combination "RP-BKA-White 7" of the small win 11, and the winning symbol combination "RP-BKA-BKB" of the small win 12 will be displayed on the activated line L1. Since it is possible to stop and display the reel, and the number of stop-displayed symbols is greater than when other symbols are stopped and displayed (for example, when the red 7 symbol "red 7" is stopped and displayed on the valid line L1, three symbol combinations can be stopped and displayed on the valid line L1, namely the winning symbol combination "red 7-RP-red 7" of minor win 14 shown in Figures 6 and 7, the winning symbol combination "red 7-RP-white 7" of minor win 15, and the winning symbol combination "red 7-red 7-RP" of minor win 34), the reel stop control based on number priority control causes the replay symbol "RP" to be stopped and displayed on the valid line L1.

[0133] As a result, in slot machine 1, when the winning area "Batting Order Bell 1" is won in the internal lottery and small prize 1, small prize 9 to small prize 12, small prize 14, small prize 15, small prize 20 to small prize 23, small prize 28, small prize 29, small prize 34, small prize 39, small prize 44, or small prize 49 is also won, the small prizes that can be won in that game are limited to small prize 9 to small prize 12.

[0134] As shown in Figures 4 and 5, the blank A symbol "BKA" on the center reel R2 and the blank A symbol "BKA" on the right reel R3 that make up the winning symbol combination "RP-BKA-BKA" for minor prize 9 can be displayed stopped on the active line L1 regardless of the timing of operation of stop button B2 and stop button B3. Therefore, if the winning area "Batting Order Bell 1" is selected in the internal lottery and stop button B1 is operated to the first stop, there is a 1 / 1 probability that minor prize 9 will be won.

[0135] In the slot machine 1, when there is no difference in the number of symbol combinations that can be stopped and displayed on the activated pay line L1 in the number-priority control, the slot machine 1 is configured to execute reel stop control using a stop control table.

[0136] In this way, in the slot machine 1 of this embodiment, when in a non-RT state, if the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A" or the winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B" is won, reel stop control using number priority control and reel stop control using a stop control table are executed, so that even if the winning area including small feature 1 and small feature 2, where the payout for a 3-coin bet game is set to 15 coins, such as the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A" or the winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B", is won, small feature 1 and small feature 2 cannot be won.

[0137] On the other hand, as shown in Fig. 10, in the slot machine 1, when the winning area "Batting Order Bell 1A" to the winning area "Batting Order Bell 4A" or the winning area "Batting Order Bell 1B" to the winning area "Batting Order Bell 4B" is won in the RBB internal state, the batting order (correct batting order) of the stop buttons B1 to B3 is set so that the small winning combination 1 and the small winning combination 2, the payout of which is set to 15 coins in a game where three coins are bet, can be won with a probability of 1 / 1, when the winning area is won in the winning area "Batting Order Bell 1C" to the winning area "Batting Order Bell 4C" or the winning area "Batting Order Bell 1D" to the winning area "Batting Order Bell 4D", when the slot machine 1 is in the non-RT state and the RBB internal state, the batting order (correct batting order) of the stop buttons B1 to B3 is set so that the small winning combination 1 and the small winning combination 2, the payout of which is set to 15 coins in a game where three coins are bet, can be won with a probability of 1 / 1, when the winning area is won in the winning area "Batting Order Bell 1C" to the winning area "Batting Order Bell 4C" or the winning area "Batting Order Bell 1D" to the winning area "Batting Order Bell 4D".

[0138] In the slot machine 1, when the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A" or the winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B" is won in the RBB internal state, or when the winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C" or the winning area "Batting Order Bell 1D" to winning area "Batting Order Bell 4D" is won in the non-RT state and the RBB internal state, if stop buttons B1 to B3 are operated in the correct batting order, the reel stop control with number priority control will stop the symbols that make up the winning combination of minor feature 1 and minor feature 2, which are set to a payout of 15 coins, on the activated line L1.

[0139] 11, in the slot machine 1, when the winning area "rare role" is won in the non-RT state and the RBB internal state, a small role set to a payout of one coin is won with a winning probability of approximately 1 / 1.3 regardless of whether the stop buttons B1 to B3 are operated in batting order 1 to batting order 6. Specifically, in the slot machine 1, when the winning area "rare role" is won in the non-RT state and the RBB internal state, if the stop buttons B1 to B3 are operated in batting order 1 and 2, small role 4 is won with a winning probability of approximately 1 / 1.3, if the stop buttons B1 to B3 are operated in batting order 3 and 4, small role 5 is won with a winning probability of approximately 1 / 1.3, and if the stop buttons B1 to B3 are operated in batting order 5 and 6, small role 6 is won with a winning probability of approximately 1 / 1.3. Details of the reel stop control when the winning area "rare role" is won will be described later.

[0140] In the slot machine 1, when the winning areas "RBB & 3 coin role 1" to "RBB & 3 coin role 8" are won in the non-RT state and the RBB internal state, if the stop buttons B1 to B3 are operated in batting order 1 and batting order 2, the small role 3, which is set to a payout of 3 coins, will be won with a winning probability of 1 / 1, and if the stop buttons B1 to B3 are operated in batting order 3 to batting order 6, one of the small roles 14 to 29 or small role 34 to 49, which are set to a payout of 1 coin, will be won with a winning probability of 1 / 8. In addition, in the slot machine 1, when the winning areas "RBB & 1 Coin Role 1" to "RBB & 1 Coin Role 16" are won in the non-RT state and the RBB internal state, if the stop buttons B1 to B3 are operated in batting order 1 and batting order 2, any of the small roles 7 to 12, which are set to a payout of 1 coin, will win with a winning probability of 1 / 1, and if the stop buttons B1 to B3 are operated in batting order 3 to batting order 6, any of the small roles 14 to 29 and small roles 34 to 49, which are set to a payout of 1 coin, will win with a winning probability of 1 / 8. Details of the reel stop control when the winning areas "RBB & 3 Coin Role 1" to "RBB & 3 Coin Role 8" and the winning areas "RBB & 1 Coin Role 1" to "RBB & 1 Coin Role 16" are won will be described later.

[0141] As shown in FIG. 12, in the slot machine 1, when the winning area "bonus small / medium win 1" is won in the RBB state, small win 1 to small win 6, which are set to one coin for a two-coin bet game, can be won depending on the operation mode of stop buttons B1 to B3. Specifically, in the slot machine 1, when stop buttons B1 to B3 are operated in batting order 1 and 2, small win 2 is won with a probability of 1 / 1. Also, in the slot machine 1, when stop buttons B1 to B3 are operated in batting order 3 and 4, small win 1 is won with a probability of 1 / 1. Also, in the slot machine 1, when stop buttons B1 to B3 are operated in batting order 5, small win 4 is won with a probability of approximately 1 / 1.3, and if small win 4 is not won, small win 3 is won with a probability of 1 / 1. In slot machine 1, when stop buttons B1 to B3 are operated in batting order 6, if the first stop operation is performed at a timing when small win 5 can be won, there is a probability of approximately 1 / 1.3 that small win 5 will be won; if small win 5 is not won and the second stop operation is performed at a timing when small win 6 can be won, there is a probability of approximately 1 / 1.3 that small win 6 will be won; if small win 5 or small win 6 is not won, small win 3 will be won with a probability of 1 / 1.

[0142] In addition, in the slot machine 1, if the winning area "bonus small / medium role 2" is won in the RBB state, regardless of whether the stop buttons B1 to B3 are operated in any of the batting orders 1 to 6, the small role 1, which has a payout set to 1 in a 2-coin bet game, will be won with a probability of 1 / 1.

[0143] <Payout of medals in each game state> 9, in the slot machine 1, when the winning area "Batting Order Bell 1A" to the winning area "Batting Order Bell 4A" or the winning area "Batting Order Bell 1B" to the winning area "Batting Order Bell 4B" is won in the internal lottery in the non-RT state, the small winning combination 1 and the small winning combination 2, which are set to pay out more than the first specified number, are not won. For this reason, the payout rate in the non-RT state is configured to be less than 50% regardless of the operation mode of the stop buttons B1 to B3.

[0144] The payout rate is the ratio of the total number of medals won during a predetermined number of games (e.g., 17,500 games), which is a number of games that is sufficient to ignore the effects of temporary probability bias, to the total number of medals inserted during the predetermined number of games.

[0145] 10, in the slot machine 1, when the stop buttons B1 to B3 are operated in batting order 1 or batting order 2 in the RBB internal state, the small prize 1 and the small prize 2, which are set to a payout greater than the first specified number, will not be awarded, and when the stop buttons B1 to B3 are operated in batting order 3 to batting order 6, the small prize 1 and the small prize 2 will be awarded. Therefore, the payout rate in the RBB internal state is configured to be less than 50% when the stop buttons B1 to B3 are operated in batting order 1 or batting order 2, and to exceed 50% when operated in any of the batting orders 3 to 6. Also, when the stop buttons B1 to B3 are operated in a random batting order in the RBB internal state, the payout rate is configured to be less than 50%.

[0146] As shown in FIG. 12, in the slot machine 1, when the winning area "bonus small / medium role 1" is won in the RBB state, the small role corresponding to the operation mode of stop button B1 to stop button B3 among small roles 1 to 6 is won, and when the winning area "bonus small / medium role 2" is won, small role 1 is won.

[0147] As shown in FIGS. 5 to 7, in the slot machine 1 of this embodiment, when a two-coin bet game is executed, the payouts for small wins 1 to 49 are set to one coin for each small win.

[0148] That is, in the slot machine 1 of this embodiment, when the slot machine transitions to the RBB state in which the specified number is set to two, and when a winning area including a small winning combination is won, one coin is paid out regardless of which small winning combination is won. Also, as described above, in the slot machine 1, in the internal lottery in the RBB state in which the internal lottery table C is used, either the winning area "bonus small / medium winning combination 1" or the winning area "bonus small / medium winning combination 2" is won.

[0149] Due to this configuration, in the slot machine 1 of this embodiment, in the RBB state, two medals are set to the inserted state and a game is executed in which one medal is paid out, so while the payout rate in the RBB state is reduced to 50%, it is possible to design the medal acquisition performance for the state in which the RBB is not activated, thereby dramatically improving the design freedom of the slot machine 1.

[0150] Furthermore, as described above, the slot machine 1 is configured so that the payout rate in the non-RT state and the RBB internal state when the stop buttons B1 to B3 are operated in a random order is less than 50%, and the payout rate in the non-RT state and the RBB internal state is lower than the payout rate in the RBB state (50%).

[0151] Due to this configuration, the slot machine 1 of this embodiment has a lower ball payout rate in the RBB state than in the non-RT state where the RBB is not operating and in the RBB internal state, and the performance of the RBB state does not deteriorate excessively, so the performance of the gaming machine can be fully guaranteed.

[0152] In addition, in the slot machine 1 of this embodiment, the payout is set to 1 coin for all small roles from small role 1 to small role 49 when a game is played with 2 coins bet, so that when a small role is won in an RBB state where the specified number is set to 2 coins, the payout number is set to 1 coin, and therefore there is no need to execute a process to set the upper limit of the payout number (upper limit setting process), and therefore the data capacity related to the program required to execute the upper limit setting process for the payout number can be reduced.

[0153] <Small winning combinations that can be won in each game state> Next, FIG. 13 is a table summarizing small winning combinations that are awarded based on winning in each gaming state of the non-RT state, the RBB internal state, and the RBB state in the slot machine 1 of this embodiment.

[0154] As shown in Figure 13, minor prize 1 and minor prize 2, the payout for which is set to 15 coins when a game with three bets is played and 1 coin when a game with two bets is played, are configured to win based on winning in the non-RT state, the RBB internal state, and the RBB state.

[0155] In addition, minor prizes 3 to 6, the payout for which is set to 3 when a 3-coin bet game is played and 1 when a 2-coin bet game is played, are configured to win based on whether they are won in the non-RT state, the RBB internal state, or the RBB state.

[0156] In addition, minor winning symbols 7 to 49, which have a payout set to 1 when a game is played with 3 coins and a payout set to 1 when a game is played with 2 coins, are configured not to win if they are won in the RBB state, but to win if they are won in the non-RT state or the state inside the RBB.

[0157] As described above, in the slot machine 1, when the second specified number (two medals) of medals are set to the inserted state and a game is started, the payouts for small prizes 1 to 49 are set to one medal.

[0158] In other words, the slot machine 1 of this embodiment is configured so that when each of small prizes 1 to 6 is won in the RBB state where two medals are set to the inserted state and play begins, the payout number is different from when three medals are set to the inserted state and play begins, and is configured so that when the play state is the RBB state for small prizes 1 to 6, a prize is won based on the win.

[0159] With this configuration, in the slot machine 1 of this embodiment, in the RBB state where the specified number is set to a second specified number, which is different from the specified number in the non-RT state and the state inside the RBB, the number of electronic medals paid out when small prize 1 to small prize 6 are won is less than the number of electronic medals paid out when a prize is won in the non-RT state and the state inside the RBB; however, by winning based on any of small prize 1 to small prize 6 in the RBB state, the performance of small prize 1 to small prize 6 is prevented from being excessively reduced, and the performance of the gaming machine can be fully guaranteed.

[0160] Also, as shown in FIG. 13, in the slot machine 1, the payout when three medals are inserted and play is started, and the payout when two medals are inserted and play is started, are both set to one, and for small prizes 7 to 49, which have the same payout amount when winning in the RBB state where two medals are inserted and play is started, and when playing is started with three medals inserted, the slot machine is configured to win when a prize is won in the non-RT state and the RBB internal state, but in the RBB state, when a prize is won, the prize will not be won regardless of the operation mode of stop buttons B1 to B3.

[0161] With this configuration, the slot machine 1 of this embodiment is configured so that in the RBB state, where the specified number is set to a second specified number, which is different from the specified number in the non-RT state and the state inside the RBB, small prizes 7 to 49, which do not result in a change in the number of electronic medals paid out when won in the RBB state and when won in the non-RT state and the state inside the RBB, are not won in the RBB state.This eliminates the need to pre-store in the reel control data storage means 194 the stop control data related to the reel stop control that allows small prizes 7 to 49 to be won, and reduces the data capacity related to the stop control data in the RBB state.

[0162] Here, as a gaming machine that suppresses the payout rate in a bonus state and makes it possible to acquire medals by executing AT play in a gaming state different from the bonus state (for example, a non-bonus state in which a bonus is not activated, such as a bonus establishment state), there has conventionally been a gaming machine that has a plurality of first winning modes in which a plurality of first specific minor roles, which are set to a payout greater than the number of game values ​​inserted required to start a game, do not overlap with each other but overlap with a second specific minor role different from the first specific minor role, and a third winning mode in which a plurality of first specific minor roles overlap and are won, and an internal lottery means In a known configuration, an internal lottery is conducted in the bonus state so that multiple types of first winning patterns exist, and in the bonus state so that a third winning pattern exists, and the probability of winning the third winning pattern in the internal lottery in the bonus state is lower than the probability of winning one of the multiple types of first winning patterns in the internal lottery in the normal game state and the bonus formation state, and the winning probability of each of all small roles in the internal lottery in the bonus state is equal to or higher than the winning probability of each of all small roles in the internal lottery in the normal game state and the bonus formation state.

[0163] In a gaming machine configured in this manner, the probability of winning the first specific minor role in the bonus state is compressed to the inverse of the number of types of first specific minor role (for example, 1 / 4 if the configuration has four types of first specific minor role), while ensuring that the performance in the bonus state is sufficient as required of a gaming machine, and by executing winning assistance for the first specific minor role in the non-bonus state, the probability of winning the first specific minor role is increased compared to when winning assistance is not executed, making it possible to win medals in AT play, but it is necessary to have multiple types of first specific minor role.

[0164] In gaming machines, for small winning combinations that can earn medals by winning, it is common for specific symbols (for example, symbols with a bell motif) to be displayed in a stopped form that is visible to the player. However, if the left reel R1 to the right reel R3 are configured so that each of the left reel R1 to the right reel R3 is visible in three frames in a specific area that makes the left reel R1 to the right reel R3 visible, the number of patterns in which the specific symbols are displayed in a row is limited to five, so if the number of types of first specific small winning combinations exceeds five, it becomes necessary to display them in the specific area in a display mode different from the display mode in which they are displayed in a row.

[0165] In addition, in gaming machines, when multiple types of small winning combinations are won in an internal lottery, there are two ways to determine the priority of the candidate stopping positions: a method of determining the priority based on the number of pattern combinations that can be displayed on the valid line L1 (number priority control), and a method of determining the priority based on the number of medals paid out based on the payout that is predetermined for the small winning combination (number priority control).

[0166] Therefore, in a gaming machine, when an operation mode of stop buttons B1 to B3 that makes it possible to win a first specific small role and an operation mode of stop buttons B1 to B3 that makes it impossible to win a first specific small role and makes it possible to win a second specific small role are set, in order to make it possible to win a second specific small role, it is necessary to make it possible to win a second specific small role by using quantity priority control.

[0167] Due to such limitations, in gaming machines, the more the types of first specific small roles are increased and the payout rate in the bonus state is compressed, the more types of second specific small roles will also increase, and an arrangement of patterns that makes it possible to win with the second specific small roles is also required, so compressing the payout rate in the bonus state tends to increase the data volume related to the small roles and make the design more difficult.

[0168] In contrast, the slot machine 1 of this embodiment is configured so that in the RBB state where the specified number is set to a second specified number (2 coins) different from the first specified number (3 coins), the payout rate is 50% when the second specified number of medals are set to the inserted state for all small roles and play begins, and the payout rate is set to a payout less than the second specified number.In this slot machine 1, the payout rate is set to 50% when the first specified number of medals are set to the inserted state and play begins, and there are two types of small roles, small role 1 and small role 2, which are set as small roles with payouts greater than the first specified number, and the performance in the RBB state can be sufficiently reduced while ensuring that the performance required of a gaming machine is sufficient.

[0169] Therefore, the slot machine 1 of this embodiment can reduce the payout rate in the RBB state and prevent the data capacity related to small winning combinations from increasing when designing medal acquisition performance for a state in which the RBB is not activated, thereby reducing the data capacity related to small winning combinations and improving the design freedom related to the arrangement of patterns.In addition, by reducing the data capacity related to small winning combinations, data capacity can be allocated to various data used in other control processes executed by the main control CPU 11, improving the design freedom of the gaming machine.

[0170] These small winning combinations 1 to 6 constitute the small winning combinations included in the second group and the predetermined group, which are made up of small winning combinations with different numbers of game values ​​paid out based on winning when a game is started after a first specified number of game values ​​is inserted and when a game is started after a second specified number of game values ​​is inserted, and small winning combinations 7 to 49 constitute the small winning combinations included in the first group, which are made up of small winning combinations with the same payout set when a game is started after a first specified number of game values ​​is inserted and when a game is started after a second specified number of game values ​​that is less than the first specified number is inserted.

[0171] 4. Combination of small winning combinations according to winning probability Next, among the minor winning combinations in which the payout is set to one coin in the three-coin bet game of the slot machine 1 of this embodiment, the minor winning combinations that can be won when the game is played in which stop buttons B1 to B3 are operated in batting order 3 and 4, in which stop button B2 is operated for the first stop, and the minor winning combinations that can be won when the game is played in which stop buttons B1 to B3 are operated in batting order 5 and 6, in which stop button B3 is operated for the first stop, will be explained in detail.

[0172] <Details of the winning area including the small winning combination set for 1 payout> As shown in Fig. 3, the slot machine 1 of this embodiment has winning areas including small roles that can be won by internal lottery in the non-RT state and the RBB internal state, such as winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A", winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B", winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C", winning area "Batting Order Bell 1D" to winning area "Batting Order Bell 4D", winning area "Rare Role", winning area "RBB & 3-Coin Role 1" to winning area "RBB & 3-Coin Role 8", and winning area "RBB & 1-Coin Role 1" to winning area "RBB & 1-Coin Role 16". Also, as shown in Figs. 3 and 5, the winning area "Rare Role" is a winning area where small roles 4 to 6, which have a payout of 3 coins in a 3-coin bet game, are won multiple times.

[0173] In the slot machine 1 of this embodiment, when the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A", the winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B", the winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C", the winning area "Batting Order Bell 1D" to winning area "Batting Order Bell 4D", the winning area "RBB & 3 Coin Role 1" to winning area "RBB & 3 Coin Role 8", or the winning area "RBB & 1 Coin Role 1" to winning area "RBB & 1 Coin Role 16" is won and the stop button B2 is operated to the first stop, and a small role with a payout set to 1 coin in a 3-coin bet game is won, one of small roles 14 to 29 will be won.

[0174] As shown in Figure 6, among the symbols on the left reel R1 to the right reel R3 that make up the winning symbol combinations of small wins 14 to 29, the symbols on the center reel R2 are all composed of replay symbols "RP", and are configured to be able to stop and display on the activated line L1 regardless of the operation timing of the stop button B2. Also, among the symbols on the left reel R1 to the right reel R3 that make up the winning symbol combinations of small wins 14 to 29, the symbols on the left reel R1 and the right reel R3 are composed of either the red 7 symbol "red 7", the white 7 symbol "white 7", the blank B symbol "BKB", or the blank C symbol "BKC".

[0175] As shown in Figure 4, on the periphery of the left reel R1, a white 7 symbol "white 7" is arranged at stop number 2, a blank B symbol "BKB" is arranged at stop number 7, a red 7 symbol "red 7" is arranged at stop number 12, and a blank C symbol "BKC" is arranged at stop number 17, and the pull-in ranges of the red 7 symbol "red 7", white 7 symbol "white 7", blank B symbol "BKB", and blank C symbol "BKC" do not overlap with each other and are configured to be 5 frames out of 20 frames.

[0176] Additionally, on the periphery of the right reel R3, a white 7 symbol "white 7" is arranged at stop number 4, a blank B symbol "BKB" is arranged at stop number 9, a red 7 symbol "red 7" is arranged at stop number 14, and a blank C symbol "BKC" is arranged at stop number 19, and the pull-in ranges of the red 7 symbol "red 7", white 7 symbol "white 7", blank B symbol "BKB", and blank C symbol "BKC" do not overlap with each other and are configured to be 5 frames out of 20 frames.

[0177] Because of this configuration, for minor wins 14 to 29, the operation timing of stop button B1 and the operation timing of stop button B3 must be the timing when 5 of the 20 frames that can stop and display the symbols that make up the winning symbol combination on the active line L1 are displayed in rotation on the active line L1. Specifically, minor win 14 can be won when stop button B1 is operated at the timing when the symbols on the left reel R1, from the red 7 symbol "RED 7" at stop number 12 to the replay symbol "RP" at stop number 16, are displayed in rotation on the active line L1, and stop button B3 is operated at the timing when the symbols on the right reel R3, from the red 7 symbol "RED 7" at stop number 14 to the replay symbol "RP" at stop number 18, are displayed in rotation on the active line L1.

[0178] For this reason, when it is not possible to determine which of the small winning symbols 14 to 29 can win a prize, and when the player is unable to perform a game aimed at stopping and displaying a specific symbol on the active line L1 when operating the stop button B1 or stop button B3, the probability of winning for each symbol is 1 / 16.

[0179] In addition, in the slot machine 1, when the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A", the winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B", the winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C", the winning area "Batting Order Bell 1D" to winning area "Batting Order Bell 4D", the winning area "RBB & 3 Coin Role 1" to winning area "RBB & 3 Coin Role 8", or the winning area "RBB & 1 Coin Role 1" to winning area "RBB & 1 Coin Role 16" is won and the stop button B3 is operated to the first stop, and a small role with a payout set to 1 coin in a 3-coin bet game is won, one of small roles 30 to 49 will be won.

[0180] As shown in Figure 6, among the symbols on the left reel R1 to the right reel R3 that make up the winning symbol combinations of small wins 30 to 33, the symbol on the right reel R3 is all composed of the cherry C symbol "CHC", and is configured to be able to stop and display on the activated line L1 regardless of the operation timing of the stop button B3. Also, among the symbols on the left reel R1 to the right reel R3 that make up the winning symbol combinations of small wins 30 to 33, the symbol on the left reel R1 and the symbol on the center reel R2 are composed of either the red 7 symbol "red 7" and the white 7 symbol "white 7", or the blank B symbol "BKB" and the blank C symbol "BKC".

[0181] As shown in Figure 4, on the periphery of the center reel R2, a white 7 symbol "White 7" is arranged at stop number 3, a blank B symbol "BKB" is arranged at stop number 8, a red 7 symbol "Red 7" is arranged at stop number 13, and a blank C symbol "BKC" is arranged at stop number 18, and the pull-in ranges of the red 7 symbol "Red 7", white 7 symbol "White 7", blank B symbol "BKB", and blank C symbol "BKC" do not overlap with each other and are configured to have a pull-in range of 5 frames out of 20 frames.

[0182] Due to this configuration, the minor winning combinations 30 to 33 require that the operation timing of the stop button B1 and the operation timing of the stop button B2 are such that the patterns of 10 frames out of 20 frames that can be stopped and displayed on the valid line L1 to form the winning combination are displayed in a rotating manner on the valid line L1. Specifically, minor win 30 can be won when stop button B1 is operated at the timing when the symbols on the left reel R1, from stop number 2 white 7 symbol "White 7" to stop number 6 replay symbol "RP", and from stop number 12 red 7 symbol "Red 7" to stop number 16 replay symbol "RP", are displayed in rotation on the valid line L1, and stop button B2 is operated at the timing when the symbols on the middle reel R2, from stop number 3 white 7 symbol "White 7" to stop number 7 blank A symbol "BKA", and from stop number 13 red 7 symbol "Red 7" to stop number 17 blank A symbol "BKA", are displayed in rotation on the valid line L1.

[0183] For this reason, when it is not possible to determine which of the small winning symbols 30 to 33 can win a prize, and when the player is unable to perform a game aimed at stopping and displaying a specific symbol on the active line L1 when operating the stop button B1 or stop button B3, the probability of winning for each symbol is set to 1 / 4.

[0184] As shown in Figure 7, among the symbols on the left reel R1 to the right reel R3 that make up the winning symbol combinations of small wins 34 to 49, the symbol on the right reel R3 is all composed of a replay symbol "RP" and is configured to be able to stop and display on the activated line L1 regardless of the operation timing of the stop button B3. Also, among the symbols on the left reel R1 to the center reel R2 that make up the winning symbol combinations of small wins 34 to 49, the symbols on the left reel R1 and the center reel R2 are composed of either a red 7 symbol "red 7", a white 7 symbol "white 7", a blank B symbol "BKB", or a blank C symbol "BKC".

[0185] Because of this configuration, for small wins 34 to 49, the operation timing of stop button B1 and the operation timing of stop button B2 must be the timing when 5 of the 20 frames that can stop and display the symbols that make up the winning symbol combination on the active line L1 are displayed in rotation on the active line L1. Specifically, small win 34 can be won when stop button B1 is operated at the timing when the symbols on the left reel R1, from stop number 12 red 7 symbol "RED 7" to stop number 16 replay symbol "RP", are displayed in rotation on the active line L1, and stop button B2 is operated at the timing when the symbols on the center reel R2, from stop number 13 red 7 symbol "RED 7" to stop number 17 blank A symbol "BKA", are displayed in rotation on the active line L1.

[0186] For this reason, when it is not possible to determine which of the small winning symbols 34 to 49 can win a prize, and when the player is unable to perform a game aimed at stopping and displaying a specific symbol on the active line L1 when operating the stop button B1 or stop button B3, the probability of winning is 1 / 16 for each symbol.

[0187] <Small prize of one coin awarded when the stop button B2 is operated for the first stop> Next, details of the case where a small winning combination with a payout set to 1 coin in a 3-coin bet game is won when the stop button B2 is operated to the first stop will be explained using Figures 9 to 11 and 14. Figure 14(A) is a diagram explaining a combination of small winning combinations with a winning probability of 1 / 2 when the stop button B2 is operated to the first stop, Figure 14(B) is a diagram explaining a combination of small winning combinations with a winning probability of 1 / 4 when the stop button B2 is operated to the first stop, and Figure 14(C) is a diagram explaining a combination of small winning combinations with a winning probability of 1 / 8 when the stop button B2 is operated to the first stop.

[0188] As shown in Figures 9 and 10, in slot machine 1, if the winning areas "Batting Order Bell 1A", "Batting Order Bell 2A", "Batting Order Bell 1B", "Batting Order Bell 2B", "Batting Order Bell 1C", "Batting Order Bell 2C", "Batting Order Bell 1D", and "Batting Order Bell 2D" are won, and stop button B2 is operated as the first stop operation, and stop buttons B1 to B3 are operated in a batting order different from the correct batting order as the second stop operation, a small winning combination with a payout set to 1 coin in a game where 3 coins are bet will be won with a 1 / 2 probability of winning.

[0189] As shown in Figure 14 (A), in the slot machine 1 of this embodiment, when the stop button B2 is operated to the first stop, the combinations that result in a winning probability of 1 / 2 for small winning combinations with a payout set to 1 in a 3-coin bet game include the combinations of small winning combinations 14, 15, 20 to 23, 28, and 29, and the combinations of small winning combinations 16 to 19 and 24 to 27.

[0190] As shown in Figure 3, in the slot machine 1, if the winning area "Batting Order Bell 1A", winning area "Batting Order Bell 2A", winning area "Batting Order Bell 1C", or winning area "Batting Order Bell 2C" is won, small prizes 14, 15, 20 to 23, 28, and 29 will be won in duplicate, and if the winning area "Batting Order Bell 1B", winning area "Batting Order Bell 2B", winning area "Batting Order Bell 1D", or winning area "Batting Order Bell 2D" is won, small prizes 16 to 19 and small prizes 24 to 27 will be won in duplicate.

[0191] As a result, in the slot machine 1, if the winning area "Batting Order Bell 1A", winning area "Batting Order Bell 2A", winning area "Batting Order Bell 1B", winning area "Batting Order Bell 2B", winning area "Batting Order Bell 1C", winning area "Batting Order Bell 2C", winning area "Batting Order Bell 1D", or winning area "Batting Order Bell 2D" is won, and the stop button B2 is operated as the first stop operation, and the stop buttons B1 to B3 are operated in a batting order different from the correct batting order as the second stop operation, a small winning combination with a payout set to 1 coin in a game where 3 coins are bet will be won with a 1 / 2 probability of winning.

[0192] As shown in Figures 9 and 10, in slot machine 1, if the winning areas "Batting Order Bell 3A," "Batting Order Bell 4A," "Batting Order Bell 3B," "Batting Order Bell 4B," "Batting Order Bell 3C," "Batting Order Bell 4C," "Batting Order Bell 3D," and "Batting Order Bell 4D" are won and the stop button B2 is operated to the first stop, a small winning combination with a payout set to 1 coin in a game where 3 coins are bet will be won with a 1 / 4 winning probability.

[0193] As shown in Figure 14 (B), in the slot machine 1 of this embodiment, when the stop button B2 is operated to the first stop, the combinations that result in a winning probability of 1 / 4 for small winning combinations with a payout set to 1 coin in a 3-coin bet game include the combination of small winning combination 14, small winning combination 19, small winning combination 24, small winning combination 29; the combination of small winning combination 15, small winning combination 20, small winning combination 25, small winning combination 26; the combination of small winning combination 16, small winning combination 21, small winning combination 22, small winning combination 27; and the combination of small winning combination 17, small winning combination 18, small winning combination 23, small winning combination 28.

[0194] As shown in FIG. 3, in the slot machine 1, when the winning area "Batting Order Bell 3A" or the winning area "Batting Order Bell 3C" is won, small prizes 14, 19, 24, and 29 are won in duplicate; when the winning area "Batting Order Bell 4A" or the winning area "Batting Order Bell 4C" is won, small prizes 15, 20, 25, and 26 are won in duplicate; when the winning area "Batting Order Bell 3B" or the winning area "Batting Order Bell 3D" is won, small prizes 16, 21, 22, and 27 are won in duplicate; and when the winning area "Batting Order Bell 4B" or the winning area "Batting Order Bell 4D" is won, small prizes 17, 18, 23, and 28 are won in duplicate.

[0195] As a result, in the slot machine 1, if the winning area "Batting Order Bell 3A", winning area "Batting Order Bell 4A", winning area "Batting Order Bell 3B", winning area "Batting Order Bell 4B", winning area "Batting Order Bell 3C", winning area "Batting Order Bell 4C", winning area "Batting Order Bell 3D", or winning area "Batting Order Bell 4D" is won and the stop button B2 is operated to the first stop, a small role with a payout set to 1 coin in a game where 3 coins are bet will be won with a 1 / 4 winning probability.

[0196] As shown in FIG. 11, in the slot machine 1, when the winning areas "RBB & 3 coin role 1" to "RBB & 3 coin role 8" and the winning areas "RBB & 1 coin role 1" to "RBB & 1 coin role 16" are won and the stop button B2 is operated to the first stop, a small role with a payout set to 1 coin in a game where 3 coins are bet will be won with a winning probability of 1 / 8.

[0207] As shown in FIG. 3, in the slot machine 1, when the winning area "Batting Order Bell 1A" or the winning area "Batting Order Bell 1C" is won, small role 34, small role 39, small role 44, small role 49 are won in duplicate; when the winning area "Batting Order Bell 2A" or the winning area "Batting Order Bell 2C" is won, small role 35, small role 40, small role 45, small role 46 are won in duplicate; when the winning area "Batting Order Bell 1B" or the winning area "Batting Order Bell 1D" is won, small role 36, small role 41, small role 42, small role 47 are won in duplicate; and when the winning area "Batting Order Bell 2B" or the winning area "Batting Order Bell 2D" is won, small role 37, small role 38, small role 43, small role 48 are won in duplicate.

[0208] As a result, in the slot machine 1, if the winning area "Batting Order Bell 3A", winning area "Batting Order Bell 4A", winning area "Batting Order Bell 3B", winning area "Batting Order Bell 4B", winning area "Batting Order Bell 3C", winning area "Batting Order Bell 4C", winning area "Batting Order Bell 3D", or winning area "Batting Order Bell 4D" is won and the stop button B2 is operated to the first stop, a small role with a payout set to 1 coin in a game where 3 coins are bet will be won with a 1 / 4 winning probability.

[0209] As shown in FIG. 11, in the slot machine 1, when the winning areas "RBB & 3 coin role 1" to "RBB & 3 coin role 8" and the winning areas "RBB & 1 coin role 1" to "RBB & 1 coin role 16" are won and the stop button B3 is operated to the first stop, a small role with a payout set to 1 coin in a game where 3 coins are bet will be won with a winning probability of 1 / 8.

[0210] As shown in Figure 15 (C), in the slot machine 1 of this embodiment, when the stop button B3 is operated to the first stop, the combinations that result in a winning probability of 1 / 8 for small winning combinations with a payout set to 1 coin in a 3-coin bet game include the combination of small winning combination 34 and small winning combination 49, the combination of small winning combination 35 and small winning combination 48, the combination of small winning combination 36 and small winning combination 47, the combination of small winning combination 37 and small winning combination 46, the combination of small winning combination 38 and small winning combination 45, the combination of small winning combination 39 and small winning combination 44, the combination of small winning combination 40 and small winning combination 43, and the combination of small winning combination 41 and small winning combination 42.

[0211] In the slot machine 1, as shown in FIG. 3, when the winning area "RBB&3 coin role 1", the winning area "RBB&1 coin role 1", and the winning area "RBB&1 coin role 9" are won, small roles 41 and 42 are won multiple times, when the winning area "RBB&3 coin role 2", the winning area "RBB&1 coin role 2", and the winning area "RBB&1 coin role 10" are won, small roles 40 and 43 are won multiple times, when the winning area "RBB&3 coin role 3", the winning area "RBB&1 coin role 3", and the winning area "RBB&1 coin role 11" are won, small roles 39 and 44 are won multiple times, and when the winning area "RBB&3 coin role 4", the winning area "RBB&1 coin role 4", and the winning area "RBB&1 coin role 12" are won, small roles 38 and 45 are won multiple times. If multiple wins occur and the winning area "RBB&3 coin role 5", winning area "RBB&1 coin role 5", winning area "RBB&1 coin role 13" is won, small role 37 and small role 46 will be won multiple times, if the winning area "RBB&3 coin role 6", winning area "RBB&1 coin role 6", winning area "RBB&1 coin role 14" is won, small role 36 and small role 47 will be won multiple times, if the winning area "RBB&3 coin role 7", winning area "RBB&1 coin role 7", winning area "RBB&1 coin role 15" is won, small role 35 and small role 48 will be won multiple times, and if the winning area "RBB&3 coin role 8", winning area "RBB&1 coin role 8", winning area "RBB&1 coin role 16" is won, small role 34 and small role 49 will be won multiple times.

[0212] As a result, in the slot machine 1, if the winning areas "RBB & 3 coin role 1" to "RBB & 3 coin role 8" or the winning areas "RBB & 1 coin role 1" to "RBB & 1 coin role 16" are won, and the stop button B3 is operated to the first stop, a small role with a payout set to 1 coin in a game where 3 coins are bet will be won with a winning probability of 1 / 8.

[0213] <Summary of winning probability of small winnings set for 1 payout> As described above, in the slot machine 1 of this embodiment, when the stop buttons B1 to B3 are operated in any of the batting orders 3 to 6 in the RBB internal state, the payout for a 3-coin bet game is 15 coins, and small winning combinations 1 and 2, which are set to a payout greater than the first specified number, can be won, so that the payout rate exceeds 50%.

[0214] For this reason, in the slot machine 1, in order to prevent the ball payout rate from increasing excessively when the stop buttons B1 to B3 are operated in any of the batting orders 3 to 6 in the RBB internal state, when the stop buttons B1 to B3 are operated in any of the batting orders 3 to 6, the slot machine is configured so that when the stop buttons B1 to B3 are operated in any of the batting orders 3 to 6, a small winning combination with a payout set to one coin in a three-coin bet game may be missed.

[0215] The slot machine 1 of this embodiment is configured so that when the stop button B2 is operated to the first stop, a small winning combination with a payout set to 1 coin in a 3-coin bet game can be missed. In each of the winning areas "Batting Order Bell 1A" to "Batting Order Bell 4A", "Batting Order Bell 1B" to "Batting Order Bell 4B", "Batting Order Bell 1C" to "Batting Order Bell 4C", "Batting Order Bell 1D" to "Batting Order Bell 4D", "RBB&3 Coin 1" to "RBB&3 Coin 8", and "RBB&1 Coin 1" to "RBB&1 Coin 16", a predetermined number of small winning combinations from small winning combinations 14 to 29, each of which has a winning probability of 1 / 16, can be won, thereby realizing a winning probability of 1 / 2, a winning probability of 1 / 4, and a winning probability of 1 / 8.

[0216] Specifically, in the slot machine 1, when the winning area "Batting Order Bell 1A", the winning area "Batting Order Bell 2A", the winning area "Batting Order Bell 1C", or the winning area "Batting Order Bell 2C" is won, eight small roles, namely, small roles 14, 15, small roles 20 to 23, small roles 28, and small roles 29, are won in duplicate, and when the winning area "Batting Order Bell 1B", the winning area "Batting Order Bell 2B", the winning area "Batting Order Bell 1D", or the winning area "Batting Order Bell 2D" is won, eight small roles, namely, small roles 16 to 19, and small roles 24 to 27, are won in duplicate. In addition, when the stop button B2 is operated as the first stop operation and the stop buttons B1 to B3 are operated in a batting order different from the correct batting order as the second stop operation, a small role with a payout set to one in a game where three coins are bet is won with a probability of winning of 1 / 2.

[0217] In addition, in slot machine 1, if you win in the winning area "Batting Order Bell 3A" or the winning area "Batting Order Bell 3C", you will receive four overlapping wins of small wins 14, 19, 24, and 29, and if you win in the winning area "Batting Order Bell 4A" or the winning area "Batting Order Bell 4C", you will receive four overlapping wins of small wins 15, 20, 25, and 26, and if you win in the winning area "Batting Order Bell 3B" or the winning area "Batting Order Bell 3D", you will receive four overlapping wins of small wins 15, 20, 25, and 26, and if you win in the winning area "Batting Order Bell 3D", you will receive four overlapping wins of small wins 15, 20, 25, and 26. When the four small winning symbols, small winning symbol 16, small winning symbol 21, small winning symbol 22, and small winning symbol 27, are overlappingly won, and when the winning area "Batting Order Bell 4B" and the winning area "Batting Order Bell 4D" are won, the four small winning symbols, small winning symbol 17, small winning symbol 18, small winning symbol 23, and small winning symbol 28, are overlappingly won, and when the stop button B2 is operated to the first stop, a small winning symbol with a payout set to 1 symbol in a game where 3 symbols are bet, with a winning probability of 1 / 4, is won.

[0218] In addition, in slot machine 1, if the winning area "RBB&3 coins 1", the winning area "RBB&1 coins 1", or the winning area "RBB&1 coins 9" is won, two small winnings, 14 and 29, will be won in duplicate, and if the winning area "RBB&3 coins 2", the winning area "RBB&1 coins 2", or the winning area "RBB&1 coins 10" is won, two small winnings, 15 and 28, will be won in duplicate, and the winning area will be "RBB&3 coins 3", "RBB&1 coins 4", or the winning area "RBB&1 coins 5", will be won in duplicate. If you win in the winning area "RBB & 3-piece role 4", the winning area "RBB & 1-piece role 4", or the winning area "RBB & 1-piece role 12", you will win two of the small roles 17 and 26, and if you win in the winning area "RBB & 3-piece role 5", the winning area "RBB & 1-piece role 5", or the winning area "RBB & 1-piece role 11", you will win two of the small roles 16 and 27, and if you win in the winning area "RBB & 3-piece role 4", the winning area "RBB & 1-piece role 4", or the winning area "RBB & 1-piece role 12", you will win two of the small roles 17 and 26, and if you win in the winning area "RBB & 3-piece role 5", the winning area "RBB & 1-piece role 5 ... If you win the rear "RBB & 1 piece role 13", two small roles 18 and 25 will be won in duplicate, and if you win the winning area "RBB & 3 piece role 6", the winning area "RBB & 1 piece role 6", or the winning area "RBB & 1 piece role 14", two small roles 19 and 24 will be won in duplicate, and if you win the winning area "RBB & 3 piece role 7", the winning area "RBB & 1 piece role 7", or the winning area "RBB & 1 piece role 15", two small roles 2 When two of the small winning symbols, 0 and small winning symbol 23, are overlappingly won, and the winning area "RBB & 3-coin symbol 8", the winning area "RBB & 1-coin symbol 8", and the winning area "RBB & 1-coin symbol 16" are won, two of the small winning symbols, 21 and 22, are overlappingly won, and when the stop button B2 is operated to make the first stop, a small winning symbol with a payout set to 1 coin in a game where 3 coins are bet will be won with a winning probability of 1 / 8.

[0219] That is, the slot machine 1 of this embodiment has small roles 14 to 29 that will be won with a winning probability of 1 / 16 when the internal lottery is won and the stop button B2 is operated to the first stop and a prize is possible. Also, the winning area "RBB&3 role 1" to winning area "RBB&3 role 8" and the winning area "RBB&1 role 1" to winning area "RBB&1 role 16" contain two of the small roles 14 to 29, and when the stop button B2 is operated to the first stop and the included small roles can be won, the included small roles can be won with a winning probability of 1 / 8, which is twice 1 / 16.

[0220] In addition, the winning areas "Batting Order Bell 3A", "Batting Order Bell 4A", "Batting Order Bell 3B", "Batting Order Bell 4B", "Batting Order Bell 3C", "Batting Order Bell 4C", "Batting Order Bell 3D", and "Batting Order Bell 4D" contain four of small winning combinations 14 to 29, and when the stop button B2 is operated to the first stop and the included small winning combination is possible, the included small winning combination has a winning probability of 1 / 4, which is four times 1 / 16.

[0221] In addition, the winning areas "Batting Order Bell 1A", "Batting Order Bell 2A", "Batting Order Bell 1B", "Batting Order Bell 2B", "Batting Order Bell 1C", "Batting Order Bell 2C", "Batting Order Bell 1D", and "Batting Order Bell 2D" contain 8 of small winning combinations 14 to 29, and when stop button B2 is operated as the first stop operation and stop buttons B1 to B3 are operated in a batting order different from the correct batting order as the second stop operation, if it is possible to win one of the included small winning combinations, there is a 1 / 2 probability of winning, which is 8 times 1 / 16.

[0222] As shown in Figure 3, minor winning combinations 14 to 29 are configured to have combinations in which at least one is commonly included in the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A", winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B", winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C", winning area "Batting Order Bell 1D" to winning area "Batting Order Bell 4D", winning area "RBB & 3-piece combination 1" to winning area "RBB & 3-piece combination 8", and winning area "RBB & 1-piece combination 1" to winning area "RBB & 1-piece combination 16". For example, minor winning combination 14 is included in the winning areas "Batting Order Bell 1A" to "Batting Order Bell 3A", "Batting Order Bell 1C" to "Batting Order Bell 3C", "RBB & 3-piece combination 1", "RBB & 1-piece combination 1", and "RBB & 1-piece combination 9".

[0223] With this configuration, the slot machine 1 of this embodiment has a winning probability of 1 / 16 in each of the winning areas "Batting Order Bell 1A" to "Batting Order Bell 4A", "Batting Order Bell 1B" to "Batting Order Bell 4B", "Batting Order Bell 1C" to "Batting Order Bell 4C", "Batting Order Bell 1D" to "Batting Order Bell 4D", "RBB & 3 Coin Role 1" to "RBB & 3 Coin Role 8", and "RBB & 1 Coin Role 1" to "RBB & 1 Coin Role 16". By adjusting the number of small winning symbols including small winning symbols 14 to 29, it is possible to configure a winning area where the probability of winning is 1 / 2 when the stop button B2 is operated to the first stop, a winning area where the probability of winning is 1 / 4, and a winning area where the probability of winning is 1 / 8.Since there is no need to separately prepare a small winning symbol where the probability of winning is 1 / 2 when the stop button B2 is operated to the first stop, a small winning symbol where the probability of winning is 1 / 4, and a small winning symbol where the probability of winning is 1 / 8, it is possible to reduce the data capacity related to the symbols.

[0224] When the predetermined reel is the center reel R2 and the predetermined stop button is the stop button B2, small wins 14 to 29 constitute the specific type of small win in this embodiment, and the probability of winning of small wins 14 to 29, which is 1 / 16, constitutes the specific probability in this embodiment. Also, when the winning areas "RBB&3-piece win 1" to "RBB&3-piece win 8" and the winning area "RBB&1-piece win 1" to "RBB&1-piece win 16", which contain two specific types of small wins that are integers greater than or equal to 1, constitute the first group of winning patterns, the winning areas "Batting Order Bell 3A", "Batting Order Bell 4A", "Batting Order Bell 3B", "Batting Order Bell 4B", "Batting Order Bell 3C", "Batting Order Bell 4C", "Batting Order Bell 3D", and "Batting Order Bell 4D", which contain four specific types of small wins that are greater than 2, constitute the second group of winning patterns in this embodiment. Furthermore, if the winning areas "Batting Order Bell 3A", "Batting Order Bell 4A", "Batting Order Bell 3B", "Batting Order Bell 4B", "Batting Order Bell 3C", "Batting Order Bell 4C", "Batting Order Bell 3D", and "Batting Order Bell 4D", which contain four specific types of small winning combinations that are integers greater than or equal to 1, are the winning patterns of the first group, then the winning areas "Batting Order Bell 1A", "Batting Order Bell 2A", "Batting Order Bell 1B", "Batting Order Bell 2B", "Batting Order Bell 1C", "Batting Order Bell 2C", "Batting Order Bell 1D", and "Batting Order Bell 2D", which contain eight specific types of small winning combinations that are greater than 4, constitute the winning patterns of the second group in this embodiment.

[0225] Furthermore, the slot machine 1 of this embodiment is configured so that when the stop button B3 is operated to the first stop, a small winning combination with a payout set to 1 coin in a 3-coin bet game may be missed. In this configuration, a predetermined number of small winning combinations from small winning combinations 34 to 49, each of which has a winning probability of 1 / 16, may be won in each of the winning areas "Batting Order Bell 1A", "Batting Order Bell 2A", "Batting Order Bell 1B", "Batting Order Bell 2B", "Batting Order Bell 1C", "Batting Order Bell 2C", "Batting Order Bell 1D", "Batting Order Bell 2D", winning areas "RBB&3 Coin Combination 1" to "RBB&3 Coin Combination 8", and winning areas "RBB&1 Coin Combination 1" to "RBB&1 Coin Combination 16", each of which has a winning probability of 1 / 16, can be won, thereby realizing a winning probability of 1 / 4 and a winning probability of 1 / 8.

[0226] Specifically, in the slot machine 1, when the winning area "Batting Order Bell 1A" and the winning area "Batting Order Bell 1C" are won, the four small roles 34, 39, 44, and 49 are won in duplicate, and when the winning area "Batting Order Bell 2A" and the winning area "Batting Order Bell 2C" are won, the four small roles 35, 40, 45, and 46 are won in duplicate, and when the winning area "Batting Order Bell 1B" and the winning area "Batting Order Bell 1D" are won, In this case, the four small winning symbols 36, 41, 42, and 47 are overlappingly won, and when the winning area "Batting Order Bell 2B" and the winning area "Batting Order Bell 2D" are won, the four small winning symbols 37, 38, 43, and 48 are overlappingly won, so that when the stop button B3 is operated to the first stop, a small winning symbol with a payout set to 1 symbol in a game where 3 symbols are bet is won with a 1 / 4 probability of winning.

[0227] In addition, in slot machine 1, if the winning area "RBB&3 coin role 1", the winning area "RBB&1 coin role 1", or the winning area "RBB&1 coin role 9" is won, two small roles, 41 and 42, will be won in duplicate, and if the winning area "RBB&3 coin role 2", the winning area "RBB&1 coin role 2", or the winning area "RBB&1 coin role 10" is won, two small roles, 40 and 43, will be won in duplicate, and the winning area will be "RBB&3 coin role 1". If you win in the winning area "RBB & 3-piece role 4", the winning area "RBB & 1-piece role 4", or the winning area "RBB & 1-piece role 11", you will receive two overlapping wins of small role 39 and small role 44. If you win in the winning area "RBB & 3-piece role 4", the winning area "RBB & 1-piece role 4", or the winning area "RBB & 1-piece role 12", you will receive two overlapping wins of small role 38 and small role 45. If you win in the winning area "RBB & 3-piece role 5", the winning area "RBB & 1-piece role 5", or the winning area "RBB & 1-piece role 13", you will receive two overlapping wins of small role 39 and small role 44. If you win the rear "RBB & 1 piece role 13", two small roles 37 and 46 will be won in duplicate, and if you win the winning area "RBB & 3 piece role 6", the winning area "RBB & 1 piece role 6", or the winning area "RBB & 1 piece role 14", two small roles 36 and 47 will be won in duplicate, and if you win the winning area "RBB & 3 piece role 7", the winning area "RBB & 1 piece role 7", or the winning area "RBB & 1 piece role 15", then the small role 3 5. When two of the small winning symbols 48 are overlappingly won and the winning area "RBB & 3 coins 8", the winning area "RBB & 1 coin 8", and the winning area "RBB & 1 coin 16" are won, two of the small winning symbols 34 and 49 are overlappingly won, so that when the stop button B2 is operated to the first stop, a small winning symbol with a payout set to 1 coin in a game where 3 coins are bet will be won with a winning probability of 1 / 8.

[0228] That is, the slot machine 1 of this embodiment has small roles 34 to 49 that will be won with a winning probability of 1 / 16 when the internal lottery is won and the stop button B3 is operated to the first stop and a prize is possible. Also, the winning area "RBB & 3-piece role 1" to the winning area "RBB & 3-piece role 8" and the winning area "RBB & 1-piece role 1" to the winning area "RBB & 1-piece role 16" contain two of the small roles 34 to 49, and when the stop button B3 is operated to the first stop and the included small roles are possible to win, the included small roles can be won with a winning probability of 1 / 8, which is twice 1 / 16.

[0229] In addition, the winning areas "Batting Order Bell 1A", "Batting Order Bell 2A", "Batting Order Bell 1B", "Batting Order Bell 2B", "Batting Order Bell 1C", "Batting Order Bell 2C", "Batting Order Bell 1D", and "Batting Order Bell 2D" contain four of small winning combinations 34 to 49, and when the stop button B3 is operated to the first stop and the included small winning combination is possible, the included small winning combination has a winning probability of 1 / 4, which is four times 1 / 16.

[0230] 3, the small winning combinations 34 to 49 are configured to have at least one combination that is commonly included in the winning areas "batting order bell 1A", "batting order bell 2A", "batting order bell 1B", "batting order bell 2B", "batting order bell 1C", "batting order bell 2C", "batting order bell 1D", "batting order bell 2D", "RBB & 3-piece combination 1" to "RBB & 3-piece combination 8", and "RBB & 1-piece combination 1" to "RBB & 1-piece combination 16". For example, the small winning combination 34 is commonly included in the winning area "batting order bell 1A", the winning area "batting order bell 1C", the winning area "RBB & 3-piece combination 8", the winning area "RBB & 1-piece combination 8", and the winning area "RBB & 1-piece combination 16".

[0231] With this configuration, the slot machine 1 of this embodiment has the winning areas "Batting Order Bell 1A", "Batting Order Bell 2A", "Batting Order Bell 1B", "Batting Order Bell 2B", "Batting Order Bell 1C", "Batting Order Bell 2C", "Batting Order Bell 1D", "Batting Order Bell 2D", winning areas "RBB&3 Coin Role 1" to "RBB&3 Coin Role 8", and winning areas "RBB&1 Coin Role 1" to "RBB&1 Coin Role 16". In each case, by adjusting the number of small winning symbols including small winning symbols 34 to 49, which have a winning probability of 1 / 16, it is possible to create a winning area with a winning probability of 1 / 4 when the stop button B3 is operated to the first stop, and a winning area with a winning probability of 1 / 8.Since there is no need to separately prepare a small winning symbol with a winning probability of 1 / 4 when the stop button B3 is operated to the first stop, and a small winning symbol with a winning probability of 1 / 8, the data volume related to the symbols can be reduced.

[0232] Furthermore, the slot machine 1 of this embodiment is configured to execute common reel stop control in the winning areas where the minor winning combinations that can be won are the same, in the winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A", in the winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B", in the winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C", in the winning area "Batting Order Bell 1D" to winning area "Batting Order Bell 4D", in the winning area "RBB&3 Coin Role 1" to winning area "RBB&3 Coin Role 8", in the winning area "RBB&1 Coin Role 1" to winning area "RBB&1 Coin Role 16", and when the stop button B2 is operated to the first stop.

[0233] Specifically, when stop buttons B1 to B3 are operated in batting order 3, small win 1 can be won, and when stop buttons B1 to B3 are operated in batting order 4, any of small win 14, small win 15, small win 20 to small win 23, small win 28, and small win 29 can be won with a probability of 1 / 2. The winning areas "Batting Order Bell 1A" and "Batting Order Bell 1C" share the same reel stop control when stop button B2 is operated for the first stop. Also, when stop buttons B1 to B3 are operated in batting order 3 and 4, the winning areas "Batting Order Bell 3A" and "Batting Order Bell 3C" share the same reel stop control when stop button B2 is operated for the first stop. When stop button B1 to stop button B3 are operated in batting order 3 and 4, the winning areas "RBB & 3 coin role 1", "RBB & 1 coin role 1", and "RBB & 1 coin role 9" have a winning probability of 1 / 8 with either small winning combination 14 or small winning combination 29, and the reel stop control when stop button B2 is operated for the first stop is the same.

[0234] Furthermore, the slot machine 1 of this embodiment is configured to execute common reel stop control in the winning areas where the minor winning combinations that can be won are the same, in regards to the reel stop control when the winning area is won in the winning area "Batting Order Bell 1A", the winning area "Batting Order Bell 2A", the winning area "Batting Order Bell 1B", the winning area "Batting Order Bell 2B", the winning area "Batting Order Bell 1C", the winning area "Batting Order Bell 2C", the winning area "Batting Order Bell 1D", the winning area "Batting Order Bell 2D", the winning area "RBB&3 Coin Role 1" to the winning area "RBB&3 Coin Role 8", the winning area "RBB&1 Coin Role 1" to the winning area "RBB&1 Coin Role 16", and the stop button B3 is operated for the first stop.

[0235] Specifically, when stop buttons B1 to B3 are operated in batting order 5 and 6, the winning areas "Batting Order Bell 1A" and "Batting Order Bell 1C" have a 1 / 4 chance of winning any of small winning combinations 34, 39, 44, and 45, and the reel stop control when stop button B3 is operated for the first stop is the same. Also, when stop buttons B1 to B3 are operated in batting order 5 and 6, the winning areas "RBB & 3 Coin Role 1", "RBB & 1 Coin Role 1", and "RBB & 1 Coin Role 9" have a 1 / 8 chance of winning any of small winning combinations 41 and 42, and the reel stop control when stop button B3 is operated for the first stop is the same.

[0236] With this configuration, the slot machine 1 of this embodiment, among the winning areas that are the targets of determining whether to win or lose by internal lottery in the non-RT state and the RBB internal state, has the following winning areas that include small roles: winning area "Batting Order Bell 1A" to winning area "Batting Order Bell 4A", winning area "Batting Order Bell 1B" to winning area "Batting Order Bell 4B", winning area "Batting Order Bell 1C" to winning area "Batting Order Bell 4C", winning area "Batting Order Bell 1D" to winning area "Batting Order Bell 4D", winning area "Rare Role", winning area "RBB Although the configuration has 41 types of winning areas, from winning area "RBB&3 coin role 1" to winning area "RBB&3 coin role 8", and winning area "RBB&1 coin role 1" to winning area "RBB&1 coin role 16", the reel stop control is common in the winning areas where the small roles that can be won are common, so the increase in data capacity related to the winning areas can be addressed by reducing the data capacity of the program code related to the reel stop control, thereby preventing the data capacity stored in the main memory means 190 from increasing excessively.

[0237] When the predetermined reel is the right reel R3 and the predetermined stop button is the stop button B3, small wins 34 to 49 constitute the specific type of small win in this embodiment, and the probability of winning of small wins 34 to 49, which is 1 / 16, constitutes the specific probability in this embodiment. Also, when the winning areas "RBB&3-piece win 1" to "RBB&3-piece win 8" and the winning area "RBB&1-piece win 1" to "RBB&1-piece win 16", which contain two specific types of small wins that are integers greater than or equal to 1, constitute the first group of winning patterns, the winning areas "Batting Order Bell 1A", "Batting Order Bell 2A", "Batting Order Bell 1B", "Batting Order Bell 2B", "Batting Order Bell 1C", "Batting Order Bell 2C", "Batting Order Bell 1D", and "Batting Order Bell 2D", which contain four specific types of small wins that are greater than 2, constitute the second group of winning patterns in this embodiment.

[0238] 5. Details of small prizes 4 to 6 and winning percentages Next, details of small wins 4 to 6 included in the winning area "rare win" of the slot machine 1 of this embodiment will be described.

[0239] <Details of small prizes 4 to 6> In a slot machine, it is necessary to be configured to observe the fairness of the game by having a winning mode in which the result of the game changes depending on the operation timing of at least one of the stop buttons B1 to B3, regardless of the order in which the player hits the stop buttons B1 to B3. In the slot machine 1 of this embodiment, when a winning area "rare combination" is won, there are cases in which small combinations 4 to 6 are won or cases in which the winning is missed (no winning) depending on the operation timing of the stop button B2 or the stop button B3.

[0240] As shown in Figure 5, the winning symbol combination for minor win 4, "RP-BL-Red 7 (White 7, BKB)" and the winning symbol combination for minor win 5, "Red 7 (White 7, CHA, BKA, BKC)-BKA-Red 7 (White 7, BKB)", can be won when the stop button B3 is operated at the timing when the white 7 symbol "White 7" at stop number 4 on the right reel R3 to the replay symbol "RP" at stop number 18 are displayed rotating on the active line L1, and therefore each is configured to have a winning probability of approximately 1 / 1.3.

[0241] In addition, the winning symbol combination for minor win 6, "Red 7 (White 7, CHA, BKA, BKC) - Red 7 (White 7, BKB) - BL", can be won when the stop button B2 is operated at the timing when the white 7 symbol "White 7" at stop number 3 on the middle reel R2 to the blank A symbol "BKA" at stop number 17 are displayed rotating on the active line L1, so it is configured to win with a winning probability of approximately 1 / 1.3.

[0242] <Winning Rate in the Slot Machine of the Present Embodiment> Next, the winning percentage in the slot machine 1 of this embodiment will be explained with reference to Figure 16. Here, the winning percentage is the ratio of the number of winning symbol combinations of minor winning combinations to the number of all symbol combinations. In slot machines, the standard stipulated in the gaming regulations requires that the winning percentage be within the range of 11% to 40%.

[0243] FIG. 16(A) is a diagram showing the winning rate in the slot machine 1 of this embodiment. As shown in FIGS. 5 to 7 and 16(A), the total number of winning symbol combinations for minor wins in the slot machine 1 of this embodiment is 952. Also, as shown in FIG. 4, the slot machine 1 of this embodiment has 20 symbols arranged on each of the peripheries of the left reel R1 to the right reel R3, so the total number of symbol combinations in the slot machine 1 is 8,000, which is the cube of 20. As a result, the slot machine 1 of this embodiment has a winning rate of 11.9%, which complies with the standards set forth in the gaming rules.

[0244] Here, in the slot machine 1, when it is configured to ensure fairness in the game by having a winning mode in which the result of the game changes depending on the timing of operation of at least one of the stop buttons B1 to B3, regardless of the order in which the player hits the stop buttons B1 to B3, if it is configured to have a minor winning feature 4, it is possible to fully guarantee the function of ensuring fairness in the game.

[0245] 16(B) is a diagram showing the winning percentage of a slot machine when it does not have small winning combinations 5 and 6. As shown in FIG. 16(B), the total number of winning combinations of small winning combinations excluding small winning combinations 5 and 6 in the slot machine 1 is 688, so the winning percentage when small winning combinations 5 and 6 are excluded is 8.6%.

[0246] Furthermore, in the slot machine 1, among the symbols that make up the winning symbol combinations of small win 5 and small win 6, the symbols on the left reel R1, the cherry A symbol "CHA" and the blank A symbol "BKA", are configured to be able to stop and be displayed on the active line L1 regardless of the timing of operation of the stop button B1. Therefore, when the slot machine is configured to ensure fairness in the game by having a winning mode in which the outcome of the game changes depending on the timing of operation of at least one of the stop buttons B1 to B3, regardless of the order in which the player hits the stop buttons B1 to B3, the slot machine is configured to have either the cherry A symbol "CHA" or the blank A symbol "BKA" as the symbol on the left reel R1 that makes up the winning symbol combinations of small win 5 and small win 6, so that the function of ensuring fairness in the game can be sufficiently guaranteed.

[0247] 16(C) is a diagram showing the winning percentage of a slot machine when configured to have only the cherry A symbol "CHA" as the symbol on the left reel R1 that constitutes the winning symbol combinations of small win 5 and small win 6. As shown in FIG. 16(C), in the slot machine 1, when the winning symbol combination of small win 5 is "CHA-BKA-red 7 (white 7, BKB)" and the winning symbol combination of small win 6 is "CHA-red 7 (white 7, BKB)-BL", the total number of winning symbol combinations of small wins is 784, so the winning percentage in this case is 9.8%.

[0248] As a result, the slot machine 1 of this embodiment is configured so that when the winning area "rare role" is won, in addition to small role 4, small role 5 and small role 6 can also be won, and the symbols on the left reel R1 that make up the winning symbol combination of small role 5 and the symbols on the left reel R1 that make up the winning symbol combination of small role 6 are configured to have the cherry A symbol "CHA" and blank A symbol "BKA", as well as the red 7 symbol "red 7", the white 7 symbol "white 7", and the blank C symbol "BKC", thereby ensuring a winning rate of over 11% and complying with the standards regarding winning rates set out in the gaming rules.

[0249] <The symbols that stop on the left reel when small wins 5 and 6 are won> As described above, in the slot machine 1 of this embodiment, the winning symbol combination for minor win 5 is composed of "Red 7 (White 7, CHA, BKA, BKC)-BKA-Red 7 (White 7, BKB)", and the winning symbol combination for minor win 6 is composed of "Red 7 (White 7, CHA, BKA, BKC)-Red 7 (White 7, BKB)-BL", and when the winning area "Rare Symbol" is won and stop buttons B1 to B3 are operated to stop in batting order 3 to 6, minor win 5 or minor win 6 can be won, and when stop button B1 is operated to stop, there are multiple candidate symbols that can be stopped and displayed on the activated line L1.

[0250] Furthermore, the gaming machine must be configured so that the winning symbol combinations of the minor winning symbols can be displayed on the pay line at any timing. For this reason, the slot machine 1 is configured so that the symbols on the left reel R1 that make up the winning symbol combinations for minor winning symbols 5 and 6, namely, the cherry A symbol "CHA", the blank A symbol "BKA", the red 7 symbol "RED 7", the white 7 symbol "WHITE 7", and the blank C symbol "BKC", can be stopped and displayed on the pay line L1.

[0251] FIG. 17 is a diagram illustrating the symbols that are stopped and displayed on the pay line L1 when the stop button B1 is operated to stop the game in a state where the small win 5 or the small win 6 can be won in the slot machine 1 of this embodiment.

[0252] As shown in Figure 17, in the slot machine 1 of this embodiment, when the stop button B1 is operated to stop when small win 5 or small win 6 is possible, the reel stop control by the reel control means 130 determines the pattern to be displayed stopped in the middle row of the left reel R1 according to the timing of operation of the stop button B1.

[0253] When the stop button B1 is operated to stop at the timing when the bell symbol "BL" at stop number 0, the replay symbol "RP" at stop number 1, the cherry A symbol "CHA" at stop number 4 to the blank B symbol "BKB" at stop number 7, the cherry A symbol "CHA" at stop number 9 to the replay symbol "RP" at stop number 11, the cherry A symbol "CHA" at stop number 14 to the replay symbol "RP" at stop number 16, and the cherry A symbol "CHA" at stop number 19 are displayed in a rotating manner on the active line L1, the reel control means 130 will stop and display the cherry A symbol "CHA" on the active line L1.

[0254] Furthermore, when the stop button B1 is operated to stop at the timing when the blank A symbol "BKA" at stop number 3, the blank A symbol "BKA" at stop number 8, the blank A symbol "BKA" at stop number 13, and the blank A symbol "BKA" at stop number 18 are displayed in rotation on the active line L1, the reel control means 130 displays the blank A symbol "BKA" stopped on the active line L1.

[0255] In addition, when the stop button B1 is operated to stop at the timing when the white 7 symbol "white 7" with stop number 2 is displayed in rotation on the activated line L1, the reel control means 130 displays the white 7 symbol "white 7" stopped on the activated line L1.

[0256] In addition, when the stop button B1 is operated to stop at the timing when the red 7 symbol "red 7" with stop number 12 is displayed in rotation on the activated line L1, the reel control means 130 displays the red 7 symbol "red 7" stopped on the activated line L1.

[0257] Then, when the stop button B1 is operated to stop at the timing when the blank C symbol "BKC" with stop number 17 is displayed in rotation on the activated line L1, the reel control means 130 displays the blank C symbol "BKC" in a stopped state on the activated line L1.

[0258] In other words, the reel control means 130 of this embodiment is configured to execute reel stop control to stop on the effective line L1 the symbol closest to the effective line L1 among the symbols located within the pull-in range from the symbol located on the effective line L1 at the time the stop button B1 is stopped, when the winning area "rare role" is won in the internal lottery in the non-RT state and RBB internal state, and the stop buttons B1 to B3 are stopped in batting order 3 to 6, thereby making it possible to win small role 5 or small role 6.

[0259] With this configuration, in order to increase the winning rate and improve the design and development environment of gaming machines, the slot machine 1 of this embodiment has a configuration in which the left reel R1 has small symbols 5 and 6, which are set as candidate symbols that can be displayed on the active line L1, and by using simple reel stop control that stops the symbol closest to the active line L1 on the active line L1 without determining which symbol will be displayed, reel stop control can be realized when the winning area ``rare symbol'' is won and stop buttons B1 to B3 are operated in an operation mode that makes it possible to win small symbols 5 and 6, so that it is possible to simplify the reel stop control that stops and displays each symbol that makes up the winning symbol combination on the active line L1 at any timing, and it is possible to reduce the program capacity related to reel stop control.

[0260] Furthermore, in order to increase the winning rate and improve the design and development environment of gaming machines, the slot machine 1 of this embodiment is configured to have small winning combinations 5 and 6, each of which has a plurality of candidate patterns that can be displayed on the activated line L1 on the left reel R1, and the patterns on the left reel R1 that make up the winning combination of small winning combination 5 and the patterns on the left reel R1 that make up the winning combination of small winning combination 6 are all configured from the same patterns, namely, cherry A pattern "CHA", blank A pattern "BKA", red 7 pattern "RED 7", white 7 pattern "WHITE 7", and blank C pattern "BKC". This allows for common reel stop control for the stop operation on stop button B1 when stop button B1 to stop button B3 are operated in an operation mode that wins the winning area "rare combination" and allows small winning combinations 5 and 6 to be won, thereby reducing the program capacity related to reel stop control.

[0261] The small wins 5 and 6 constitute the specific small wins in this embodiment, the left reel R1 constitutes the specific reel in this embodiment, the stop button B1 constitutes the specific stop button in this embodiment, the positions of stop numbers 4, 9, 14, and 19 on the left reel R1 where the cherry A symbol "CHA" is arranged constitute the first positions in this embodiment, the positions of stop numbers 3, 8, 13, and 18 on the left reel R1 where the blank A symbol "BKA" is arranged, the position of stop number 2 where the white 7 symbol "WHITE 7" is arranged, the position of stop number 12 where the red 7 symbol "RED 7" is arranged, and the position of stop number 17 where the blank C symbol "BKC" is arranged constitute the second positions in this embodiment, and the non-RT state and the RBB internal state constitute the specific game states in this embodiment.

[0262] 6. Summary of this embodiment As described above, in order to increase the winning rate and improve the design and development environment for gaming machines, the slot machine 1 of this embodiment has a configuration in which the left reel R1 has small symbols 5 and 6, which are set as candidate symbols that can be displayed on the active line L1, and by using a simple reel stop control that stops the symbol closest to the active line L1 on the active line L1 without determining which symbol will be displayed, reel stop control can be realized when the winning area ``rare symbol'' is won and stop buttons B1 to B3 are operated in an operation mode that makes it possible to win small symbols 5 and 6, so that it is possible to simplify the reel stop control that stops and displays each symbol that makes up a winning symbol combination on the active line L1 at any timing, and it is possible to reduce the program capacity related to the reel stop control.

[0263] 7. Variations In this embodiment, the slot machine 1 configures a winning mode with a 1 / 8 probability of winning by having two specific types of small roles with a 1 / 16 probability of winning, configures a winning mode with a 1 / 4 probability of winning by having four specific types of small roles with a 1 / 4 probability of winning, and configures a winning mode with a 1 / 2 probability of winning by having eight specific types of small roles with a 1 / 2 probability of winning, but is not limited to this. For example, the slot machine 1 may configure a winning mode with a 3 / 16 probability of winning by having three specific types of small roles with a 1 / 16 probability of winning, or may configure a winning mode with a 1 / 16 probability of winning by having one specific type of small role with a 1 / 16 probability of winning.

[0264] Furthermore, the slot machine 1 is configured to have a specific type of small win with a winning probability of 1 / 16, but is not limited to this. For example, the specific type of small win may have a small win with a winning probability of 1 / 8, or may have any winning probability as long as it is configured with a winning probability of 1 / 2 or less.

[0265] In other words, the slot machine 1 is configured so that the winning patterns of the first group include n (n is an integer equal to or greater than 1) specific types of small roles, and the winning patterns of the second group include m (m is an integer greater than n) specific types of small roles, so that when the winning pattern of the first group is won in the internal lottery, and the predetermined stop button is operated to stop first, and a specific type of small role can be won, the probability that any of the winning specific type of small roles will win is n times the specific probability, and when the winning pattern of the second group is won in the internal lottery, and the predetermined stop button is operated to stop first, and a specific type of small role can be won, the probability that any of the winning specific type of small roles will win is m times the specific probability, and the probability of winning a specific type of small role, the number of specific type of small roles included in the winning patterns of the first group, and the number of specific type of small roles included in the winning patterns of the second group are not limited to this embodiment.

[0266] In the present embodiment, the symbols on the left reel R1 and the right reel R3 that make up the winning symbol combinations for small wins 14 to 29 are either a red 7 symbol "RED 7," a white 7 symbol "WHITE 7," a blank B symbol "BKB," or a blank C symbol "BKC," but are not limited thereto. In the slot machine 1, the symbols on the left reel R1 and the right reel R3 that make up the winning symbol combinations for small wins 14 to 29 may be different. In the slot machine 1, the symbols on the left reel R1 and the center reel R2 that make up the winning symbol combinations for small wins 34 to 49 are either a red 7 symbol "RED 7," a white 7 symbol "WHITE 7," a blank B symbol "BKB," or a blank C symbol "BKC," but are not limited thereto. The slot machine 1 may be configured such that the symbols on the left reel R1 and the symbols on the center reel R2 that form the winning symbol combinations of small win 34 to small win 49 are different from each other.

[0267] When configured in this manner, the slot machine 1 will need to increase the number of patterns that can be arranged on the left reel R1 to the right reel R3, since the cherry A symbol "CHA" to the cherry C symbol "CHC" will be composed of a common symbol (for example, the cherry symbol "CH").

[0268] In this embodiment, the slot machine 1 is configured so that the symbols arranged at the first positions on the left reel R1 are the same symbols, i.e., the cherry A symbol "CHA" arranged at positions 4, 9, 14, and 19. However, this is not limiting. The slot machine 1 may be configured so that the symbols arranged at the first positions are arranged in positions where their pull-in ranges do not overlap each other and are different types of symbols, such as, for example, the white 7 symbol "WHITE 7" at stop 2, the blank B symbol "BKB" at stop 7, the red 7 symbol "RED 7" at stop 12, and the blank C symbol "BKC" at stop 17.

[0269] Furthermore, in this embodiment, the slot machine 1 has the symbols on the left reel R1 that make up the winning symbol combination for minor win 5, including the cherry A symbol "CHA" and the blank A symbol "BKA", as well as the red 7 symbol "RED 7", the white 7 symbol "WHITE 7", and the blank C symbol "BKC", and the symbols on the left reel R1 that make up the winning symbol combination for minor win 6, including the cherry A symbol "CHA" and the blank A symbol "BKA", as well as the red 7 symbol "RED 7", the white 7 symbol "WHITE 7", and the blank C symbol "BKC", but are not limited to these. The slot machine 1 only needs to be configured so that the symbols on the left reel R1 that make up the winning combinations of small win 5 and small win 6 have a winning rate of 11% or more. For example, the symbols on the left reel R1 that make up the winning combinations of small win 5 and small win 6 may be configured to have the cherry A symbol "CHA" and the blank A symbol "BKA", but not have the red 7 symbol "red 7", the white 7 symbol "white 7", or the blank C symbol "BKC", so that the number of winning combinations of small wins is 880, and the winning rate is 11%.

[0270] In addition, in this embodiment, the symbols on the left reel R1 that make up the winning symbol combination for minor win 5 and the symbols on the left reel R1 that make up the winning symbol combination for minor win 6 are configured with the same Cherry A symbol "CHA," Blank A symbol "BKA," Red 7 symbol "RED 7," White 7 symbol "WHITE 7," and Blank C symbol "BKC." However, this is not limiting. In the slot machine 1, the symbols on the left reel R1 that make up the winning symbol combination for minor win 5 and the symbols on the left reel R1 that make up the winning symbol combination for minor win 6 may be configured with different symbols.

[0271] In this embodiment, the slot machine 1 has a left reel R1 as the specific reel, but is not limited to this. For example, the slot machine 1 may have a center reel R2 or a right reel R3 as the specific reel. When the center reel R2 is the specific reel, the slot machine 1 has a stop button B2 as the specific stop button, and when the right reel R3 is the specific reel, the slot machine 1 has a stop button B3 as the specific stop button.

[0272] Furthermore, in this embodiment, the slot machine 1 is configured so that the payout number of electronic medals when a two-coin bet game is executed is one by setting the payout for all of the small roles 1 to 49 to one when a two-coin bet game is executed, but is not limited to this. For example, when a two-coin bet game is executed, the slot machine 1 may be configured so that the payout of one medal is executed regardless of the number of medals set for the winning small role by executing a process to set the upper limit of the payout number to one.

[0273] Below, a detailed description will be given of a configuration in which a process for setting an upper limit on the number of payouts (upper limit setting process) is executed to play a two-coin bet game and one electronic medal is paid out regardless of which minor winning combination is won. A slot machine 1 configured in this way is configured to set an upper limit on the number of electronic medals that can be paid out when a two-coin bet game is played, and is configured to set the number of payouts to the upper limit and pay out medals when a minor winning combination with a payout set to equal or exceed the upper limit is won. Specifically, the slot machine 1 is configured to set one medal as the upper limit on the number of electronic medals that can be paid out when a two-coin bet game is played.

[0274] Fig. 18 is a flowchart showing an upper limit setting process in which the slot machine 1 of the modified example sets an upper limit of the payout number. The process shown in Fig. 18 is executed after the payout value set for the winning minor winning combination is stored in the payout number storage means 199 (see Fig. 2) of the main storage means 190 in the payout process by the payout control means 150, which is executed when a minor winning combination is won.

[0275] 18, the payout control means 150 first acquires the payout number stored in the payout number storage means 199 (S1). In this process, the payout control means 150 acquires the stored value of the payout number storage means 199, which stores the payout value set for the small winning combination in the current game.

[0276] Next, the payout control means 150 checks the number of electronic medals that have been set to the inserted state for the current game (S2). In this process, the payout control means 150 checks the value stored in the inserted number storage means 198, thereby making it possible to determine whether the current game is a two-coin bet game or a three-coin bet game.

[0277] Next, the payout control means 150 determines whether or not the number of electronic medals set to the inserted state in the current game is two (S3). In this process, the payout control means 150 determines whether or not the stored value of the inserted number storage means 198 (see FIG. 2) confirmed in the process of step S2 is the value "2". By the payout control means 150 executing the process of step S3, the slot machine 1 can determine whether or not the current game has been executed in the RBB state in which the second specified number (two medals) is set.

[0278] In the process of step S3, when it is determined that the number of electronic medals set to the inserted state in the current game is two (YES), the payout control means 150 determines whether the number of payouts in the current game is two or more (S4). In this process, the payout control means 150 determines whether the number of payouts stored in the payout number storage means 199 obtained in the process of step S1 is a value of "2" or more.

[0279] In the process of step S4, if it is determined that the number of payouts in the current game is two or more (YES), the payout control means 150 sets the number of payouts to one (S5). In this process, the payout control means 150 changes the value of two or more stored in the payout number storage means 199 to the value "1", thereby setting the number of payouts in the current game to one.

[0280] This processing in step S5 constitutes a process for setting the upper limit of the number of electronic medals that can be paid out to a specific number (1 medal) that is less than the second specified number (3 medals) when a game is started by inserting a second specified number (2 medals) that is less than the first specified number (3 medals).

[0281] After executing the processing of step S5, if it is determined in the processing of step S3 that the number of electronic medals set to the inserted state for the current game is three (NO), or if it is determined in the processing of step S4 that the number of medals to be paid out for the current game is one (NO), the payout control means 150 executes processing to pay out medals (S6) and ends the payout processing. In this processing, the payout control means 150 determines the value stored in the payout number storage means 199 as the number of medals to be paid out for the game, and adds the number of electronic medals corresponding to the determined number to the medal number counter 311.

[0282] In this way, when a three-coin bet game is executed, the payout control means 150 is configured to skip the processing of steps S4 and S5 from step S3 and proceed to step S6, determine the stored value of the payout number storage means 199, which stores the value set as the payout for the small winning combination won in the game, as the number of medals to be paid out in the game, and add the number of electronic medals corresponding to the determined payout number to the medal number counter 311.

[0283] Due to this configuration, the slot machine 1 is configured to pay out the same number of electronic medals as the payout set for the winning minor role in the non-RT state and the RBB internal state, and when a minor role with a payout set to more than one medal is won, the payout of the payout is executed.

[0284] On the other hand, when a two-coin bet game is played and a small role with a payout of two or more coins set as the payout for the two-coin bet game is won, the payout control means 150 is configured to execute the processing of step S5 and then proceed to step S6, and determines the stored value of the payout number memory means 199, which is set to the value "1", as the number of medals to be paid out in the game, regardless of the value set as the payout for the small role won in the game, and adds the number of electronic medals (1 medal) corresponding to the determined payout number to the medal number counter 311.

[0285] Because of this configuration, in the slot machine 1, when a game with three bets is executed and when a game with two bets is executed, the payout is the same, and when a minor role with a payout set to more than one coin is won in the RBB state when a game with two bets is executed, a payout of one coin is executed, which is less than the set payout and is less than the specified number (2 coins) in the RBB state.

[0286] That is, in the slot machine 1, when the specified number is set to the RBB state of 2 coins and a win area including a small winning combination is won, one coin is paid out regardless of which of all the small winning combinations is won. In other words, in the slot machine 1, when the specified number is set to the second specified number (2 coins) and a small winning combination with a payout set to a payout greater than the second specified number is won, a payout less than the second specified number is paid out.

[0287] With this configuration, the slot machine 1 transitions to an RBB state where the specified number is set to two coins, and when a winning area including a small win is won, a process for setting an upper limit on the number of payouts is executed, so that one coin is paid out regardless of which of all the small wins is won. This reduces the payout rate in the RBB state to 50% and makes it possible to design medal acquisition performance for when the RBB is not activated, thereby dramatically improving the design freedom of the slot machine 1.

[0288] Furthermore, as described above, the slot machine 1 is configured so that the payout rate in the non-RT state and the RBB internal state when the stop buttons B1 to B3 are operated in a random order is less than 50%, and the payout rate in the non-RT state and the RBB internal state is lower than the payout rate in the RBB state (50%).

[0289] With this configuration, the ball payout rate in the RBB state of the slot machine 1 is lower than that in the non-RT state in which the RBB is not operating and the RBB internal state, and the performance of the RBB state does not deteriorate excessively, so the performance of the gaming machine can be fully guaranteed.

[0290] Furthermore, by configuring the slot machine 1 to execute an upper limit value setting process, the payout number when a two-coin bet game is executed can be set to one coin without having to set the payout when a two-coin bet game is executed for each minor role separately from the payout when a three-coin bet game is executed, thereby reducing the data volume required to set the payout when a two-coin bet game is executed for each minor role.

[0291] In addition, when configured in this manner, the slot machine 1 is required to be configured so that when the game state is in the RBB state, a prize is awarded based on a win for a minor role that is configured to result in a different payout number when a prize is awarded in the RBB state in which two medals are set to the inserted state and play is started, and when three medals are set to the inserted state and play is started.

[0292] As a result, in the RBB state where the prescribed number is set to a second prescribed number, which is different from the prescribed number in the non-RT state and the state inside the RBB, the slot machine 1 can win a minor winning combination in which the number of electronic medals paid out is less than the number of electronic medals that would be paid out if a winning combination was won in the non-RT state and the state inside the RBB, by winning in the RBB state, preventing the performance of the minor winning combination from being excessively reduced and fully guaranteeing the performance of the gaming machine.

[0293] When configured in this manner, minor winning combinations that have different numbers of game values ​​paid out based on winning when a first specified number of game values ​​is inserted and game play is started and when a second specified number of game values ​​is inserted and game play is started constitute minor winning combinations included in the second group and the predetermined group, and minor winning combinations that have the same number of game values ​​paid out based on winning when a first specified number of game values ​​is inserted and game play is started and when a second specified number of game values ​​that is less than the first specified number is inserted and game play is started constitute minor winning combinations included in the first group.

[0294] In addition, in this embodiment, the slot machine 1 is configured to switch the small winning combination that can be won depending on the hitting order and operation timing of the stop buttons B1 to B3 when the winning area "bonus small / medium winning combination 1" is won, but is not limited to this. The slot machine 1 may be configured to switch the small winning combination that can be won depending on the operation mode of the stop buttons B1 to B3 when the winning area "bonus small / medium winning combination 1" is won.

[0295] In addition, in this embodiment, the slot machine 1 is configured to have a non-RT state and an RBB internal state as the first gaming state, and an RBB state as the second gaming state, but is not limited to this. The slot machine 1 may be configured to have, for example, the following game states in a game state in which the RBB is won and the RBB is activated: a non-RT state, an RBB internal state, a general RBB activated state in which the RBB is activated and the RB is not won or won and the RB is not activated, an RBB activated RB internal state in which the RBB is activated and the RB is won and the RB is not activated, and an RBB activated RB state in which the RBB is activated and the RB is won and the RB is activated.When configured in this way, the game states in which the probability of winning a small role in the internal lottery is the same in the non-RT state, the RBB internal state, the general RBB activated state and the RBB activated RB internal state may constitute a first game state, and the RBB activated RB activated state in which the probability of winning any small role in the internal lottery is higher than in the first game state may constitute a second game state.

[0296] In addition, in this embodiment, the slot machine 1 is configured not to notify whether or not it is in an advantageous zone, but this is not limiting. For example, the slot machine 1 may be configured to notify that it is in an advantageous zone when the expected value of medal acquisition is 1 or more due to the support of winning a small winning combination.

[0297] Furthermore, in this embodiment, the slot machine 1 has a plurality of reels, namely, left reel R1 to right reel R3, and a plurality of stop buttons, namely, stop buttons B1 to B3, corresponding to the left reel R1 to right reel R3, but is not limited to this and may have, for example, a fourth reel and a stop button corresponding to the fourth reel.

[0298] In addition, in this embodiment, the slot machine 1 has a max bet button MB for inserting a specified number of medals, but this is not limited to this, and for example, it may be configured to have a single bet button for inserting one medal in addition to the max bet button MB.

[0299] When configured in this way, the slot machine 1 may be configured to be able to start a game when either the first specified number or the second specified number of electronic medals is set to the inserted state, with respect to the specified number in the non-RT state or the RBB state. When configured in this way, the slot machine 1 may be configured to set the first specified number of electronic medals to the inserted state when the max bet button MB is operated when the gaming state is the non-RT state or the RBB state, and to set the second specified number of electronic medals to the inserted state when the single bet button is operated twice.

[0300] In this embodiment, the slot machine 1 is configured as a so-called medalless gaming machine that records gaming value electromagnetically, but is not limited to this. The slot machine 1 may be configured to allow medals, which serve as physical media for gaming value, to be inserted, and to allow the physical media medals to be paid out using a hopper unit. In this configuration, the slot machine 1 is configured to be able to credit up to 50 inserted medals. In this configuration, the AT control means 170 ends the advantageous zone when 4,000 games have been played since the advantageous zone began.

[0301] Furthermore, in this embodiment, the slot machine 1 is configured to set the stored value of each counter and memory means as an initial value, and to perform a decrement update by subtracting 1 each time a game is played, or an increment update by adding 1 each time a game is played, but this is not limited to this, and the method of updating each counter and memory means may be configured to perform multiplication, division, etc., and is not particularly limited.
