[0012] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0013] In order to facilitate understanding of the embodiments of the present invention, first, a brief description will be given of the mechanical and electrical configurations of the gaming machine, and then specific processing on each board will be described.

[0014] 1 is a perspective view of a gaming machine 100 with the door open. As shown in the figure, the gaming machine 100 includes an outer frame 102 having an enclosed space formed by four sides assembled into a substantially rectangular shape, a middle frame 104 attached to the outer frame 102 by a hinge mechanism so as to be freely opened and closed, and a front frame 106 attached to the middle frame 104 by a hinge mechanism so as to be freely opened and closed.

[0015] The middle frame 104, like the outer frame 102, has four sides arranged in a substantially rectangular shape to form an enclosed space, and a game board 108 is held in this enclosed space. A glass or resin transparent plate 110 is held in the front frame 106. When the middle frame 104 and the front frame 106 are closed against the outer frame 102, the game board 108 and the transparent plate 110 face each other substantially parallel to each other while maintaining a predetermined distance therebetween, and the game board 108 can be seen from the front side of the gaming machine 100 through the transparent plate 110.

[0016] Fig. 2 is a front view of the gaming machine 100, and Fig. 3 is a front view of the gaming board 108. However, Fig. 2 shows a state in which the gaming board 108 has been removed.

[0017] 2, an operating handle 112 that protrudes from the front side of the gaming machine 100 is provided at the bottom of the front frame 106. This operating handle 112 is provided so as to be rotatable by the player, and when the player rotates the operating handle 112 to perform a firing operation, a gaming ball is fired by a firing mechanism (not shown) with a strength according to the rotation angle of the operating handle 112.

[0018] The game ball thus launched rises between rails 114a, 114b provided on the game board 108 and is guided to a game area 116, as shown in FIG.

[0019] The play area 116 is a space formed between the play board 108 and the transparent plate 110, and is an area in which the play balls can flow down or roll. The play board 108 is provided with a large number of nails and windmills, and the play balls guided to the play area 116 collide with the nails and windmills, causing them to flow down or roll in irregular directions.

[0020] The play area 116 includes a first play area 116a and a second play area 116b, which have different degrees of entry of game balls depending on the launch strength of the launch mechanism. The first play area 116a is located on the left side of the play area 116 as seen by a player facing the game machine 100, and the second play area 116b is located on the right side of the play area 116 as seen by a player facing the game machine 100. Since the rails 114a and 114b are on the left side of the play area 116, game balls launched by the launch mechanism with a launch strength less than a predetermined strength will enter the first play area 116a, and game balls launched with a launch strength equal to or greater than the predetermined strength will enter the second play area 116b.

[0021] In addition, the game area 116 is provided with a general winning hole 118, a first starting hole 120, and a second starting hole 122 through which game balls can enter, and when game balls enter the general winning hole 118, the first starting hole 120, and the second starting hole 122, a predetermined prize ball is paid out to the player. The number of prize balls may be any number greater than or equal to one, and the number of prize balls paid out from the general winning hole 118, the first starting hole 120, and the second starting hole 122 may be different or may be set to the same number of prize balls. In this case, it is also possible to set the number of prize balls paid out when a game ball enters the first starting hole 120 to be less than the number of prize balls paid out when a game ball enters the second starting hole 122.

[0022] In addition, as will be described later in detail, a first starting area is provided in the first starting hole 120, and a second starting area is provided in the second starting hole 122. When a game ball enters the first starting hole 120 or the second starting hole 122 and enters the first starting area or the second starting area, a lottery is held to determine one of a plurality of special patterns provided in advance. Each special pattern is associated with various game benefits, such as whether or not a small winning game advantageous to the player can be executed, and what kind of game state the game state will be from then on. Therefore, when a game ball enters the first starting hole 120 or the second starting hole 122, the player will acquire a predetermined prize ball and at the same time, will acquire the opportunity to acquire the right to receive various game benefits.

[0023] The first starting hole 120 is located at the bottom of the game area 116, and is either capable of being entered by game balls flowing down the first game area 116a, or is located at a position where game balls that have entered the first game area 116a can enter more easily than game balls that have entered the second game area 116b.

[0024] The second starting hole 122 is located in the second game area 116b, and only game balls flowing down the second game area 116b can enter, or is located in a position where game balls that have entered the second game area 116b can enter more easily than game balls that have entered the first game area 116a. The second starting hole 122 is configured by a variable starting hole (a variable starting winning device) having a movable piece 122b, and the ease of entry of game balls into the second starting hole 122 can be changed.

[0025] 4 is a partially enlarged view of the game board 108. The specific configuration of the second start opening 122 is not particularly limited, but here, the movable piece 122b is usually recessed into the back side of the game board 108, the second start opening 122 is closed, and the game ball flows down the front side of the movable piece 122b, making it impossible or difficult for the game ball to enter the second start opening 122.

[0026] In contrast, when the game ball passes through the gate 124 provided in the second game area 116b, the movable piece 122b protrudes to the front side of the game board 108, and it is determined whether or not to execute an auxiliary game that makes it easier for the game ball to enter the second starting hole 122. When it is determined that an auxiliary game is to be executed, the movable piece 122b protrudes to the front side of the game board 108, and the auxiliary game that makes it easier for the game ball to enter the second starting hole 122 is executed. In more detail, on the condition that the game ball has passed through the gate 124, a lottery for a normal symbol, which will be described later, is held, and if a winning combination is selected in this lottery, the movable piece 122b is controlled to be in an open state for a predetermined time.

[0027] When the movable piece 122b is in the protruding state, a game ball flowing down the front side of the movable piece 122b falls onto the movable piece 122b. The game ball that has fallen onto the movable piece 122b is guided by the movable piece 122b and guided to the second starting hole 122. In this way, when the movable piece 122b is in the protruding state, the movable piece 122b functions as a tray that guides the game ball to the second starting hole 122, making it easier for the game ball to enter the second starting hole 122.

[0028] Furthermore, a big prize opening 128 is provided at the bottom of the game area 116. The big prize opening 128 is disposed at a position where at least a game ball flowing down the second game area 116b can enter.

[0029] Also, the big prize opening 128 is provided with a movable piece 128b that can be opened and closed, and normally, the movable piece 128b closes the big prize opening 128, making it impossible for game balls to enter the big prize opening 128. In contrast, when a small prize game or a big role game is executed, the movable piece 128b is opened, making it possible for game balls to enter the big prize opening 128.

[0030] When a game ball enters the big prize opening 128, a predetermined number of prize balls are paid out to the player. In the embodiment, 15 game balls are paid out to the player as prize balls for one game ball entering the big prize opening 128. In other words, by having a game ball enter the big prize opening 128, the player can increase the number of game balls he or she owns.

[0031] As shown in Fig. 4, the second game area 116b is provided with a structure 129 that protrudes from the front side of the game board 108. This structure 129 has an opening formed in the upper part, which serves as the big prize opening 128. A movable piece 128b is provided on the upper part of the structure 129, and the movable piece 128b is normally maintained in a closed state in which the big prize opening 128 is closed.

[0032] The movable piece 128b protrudes into the game area 116 where the game balls roll and flow down so as to face the upper part of the game machine 100. Therefore, when the movable piece 128b is maintained in the closed state, the game balls flowing down the game area 116 (the second game area 116b) fall onto the movable piece 128b.

[0033] Here, the movable piece 128b maintained in the closed state is inclined so that the left side of the gaming machine 100 is slightly lower than the right side. Therefore, when the movable piece 128b is in the closed state, a gaming ball that has fallen onto the movable piece 128b will slowly roll from right to left on the movable piece 128b.

[0034] Inside the big prize opening 128, a lead-out path 128d is provided, and all game balls that enter the big prize opening 128 are led to the lead-out path 128d. The lead-out path 128d is provided with a specific area 140b and a non-specific area 140c, each of which is made up of holes through which the game balls can pass, and is configured so that the game balls that enter the big prize opening 128 pass through either the specific area 140b or the non-specific area 140c.

[0035] The big prize opening 128 is provided with a movable member 142 that opens and closes the specific area 140b and the non-specific area 140c. The movable member 142 appears and disappears in the front-rear direction (front-rear direction) of the gaming machine 100 from a hole formed in the gaming board 108 by an actuator (solenoid) not shown. Normally, the actuator is maintained in a non-energized state, and the movable member 142 is held in a position protruding from the hole in the gaming board 108 to the front side, making it impossible for a gaming ball to enter the specific area 140b. More specifically, when the movable member 142 is held in a position protruding from the hole in the gaming board 108 to the front side, the specific area 140b is blocked by the movable member 142, and the gaming ball can pass through the non-specific area 140c.

[0036] Moreover, when the actuator is energized, the movable member 142 is held in a position recessed on the rear side of the hole in the game board 108, and is in a state in which the game ball can enter the specific area 140b. More specifically, when the movable member 142 is held in a position recessed on the rear side of the hole in the game board 108, the specific area 140b is opened, and the game ball can pass through the specific area 140b. As will be described in detail later, when the game ball enters the specific area 140b in the small win game, a big win (type 2 big win) is obtained, and a big role game described later is started.

[0037] When a small win game or a big win game is executed, the movable piece 128b transitions to an open state in which the big prize opening 128 is opened. Here, the movable piece 128b is caused to protrude from a hole formed in the game board 108 in the front-rear direction (front-rear direction) of the game machine 100 by an actuator (solenoid) not shown. Normally, the actuator is maintained in a non-energized state, and the movable piece 128b is held in a position protruding from the hole in the game board 108 to the front side, and the big prize opening 128 is closed. When the actuator is energized, the movable piece 128b is held in a position retracted from the hole in the game board 108 to the rear side, and the big prize opening 128 is opened. In this way, when the big prize opening 128 is in an open state, a game ball enters the big prize opening 128.

[0038] Returning to Figure 3, at the bottom of the game area 116, there is an outlet 130 that discharges game balls that do not enter the general prize opening 118, the first start opening 120, the second start opening 122, or the large prize opening 128 from the game area 116 to the back side of the game board 108.

[0039] The gaming machine 100 is equipped with a performance display device 200 consisting of a liquid crystal display device, a performance prop device 202 consisting of a movable device, a performance lighting device 204 consisting of lamps that can be controlled to various lighting modes and emission colors, an audio output device 206 consisting of a speaker, and a performance button 208 that accepts operation by the player, as performance devices that perform performance while the game is in progress.

[0040] The effect display device 200 also includes a main effect display section 200a that is an image display section that displays images. The main effect display section 200a is arranged in the approximate center of the game board 108 so as to be visible from the front side of the gaming machine 100. Various images for effects are displayed on the main effect display section 200a.

[0041] The performance prop device 202 is positioned in front of the main performance display section 200a and is normally retracted to the rear side of the game board 108. It moves to the front of the main performance display section 200a in accordance with the image displayed on the main performance display section 200a, giving the player a sense of anticipation.

[0042] The effect lighting device 204 is provided on the effect part device 202, the game board 108, etc., and is controlled to light in various ways in accordance with the images displayed on the main effect display section 200a.

[0043] Returning to Figure 2, the audio output device 206 is provided at the upper position of the front frame 106 or at the lowermost position of the outer frame 102, and outputs various sounds toward the front of the gaming machine 100 in accordance with the images displayed on the main performance display section 200a.

[0044] The effect button 208 is composed of a button that accepts a press operation by the player, and is provided at approximately the center position in the width direction of the gaming machine 100, and at a position lower than the transparent plate 110. This effect button 208 is activated according to the image displayed on the main effect display section 200a, and when the operation of the player is accepted within the operation effective time, various effects are executed according to the operation.

[0045] In addition, the reference numeral 132 in the figure denotes an upper tray to which prize balls paid out from the gaming machine 100 and gaming balls lent out from the gaming ball lending device are guided, and when this upper tray 132 is filled with gaming balls, the gaming balls are guided to a lower tray 134. A ball ejection hole (not shown) for ejecting gaming balls from the lower tray 134 is formed in the bottom surface of the lower tray 134. This ball ejection hole is normally closed by an opening / closing plate (not shown), but by pushing in a ball ejection knob 134a, the opening / closing plate slides together with the ball ejection knob 134a, making it possible to eject gaming balls from the ball ejection hole to the bottom of the lower tray 134.

[0046] In addition, on the game board 108, a first special symbol display 160, a second special symbol display 162, a first special symbol reserved display 164, a second special symbol reserved display 166, a normal symbol display 168, a normal symbol reserved display 170, and a right hit notification display 172 are provided outside the game area 116 and at positions visible to the player. Each of these displays 160 to 172 is a device for displaying various situations related to the game, and the details thereof will be described later.

[0047] (Internal configuration of control means) FIG. 5 is a block diagram showing the internal configuration of a control means for controlling the progress of a game.

[0048] The main control board 300 controls the basic operation of the game. This main control board 300 is equipped with a main CPU 300a, a main ROM 300b, and a main RAM 300c.

The out ball detection switch 130s is provided in the junction passage, and all game balls discharged from the game area 116, in other words, all game balls shot into the game area 116, are detected by the out ball detection switch 130s.

[0052] In addition, the main control board 300 is connected to a normal electric device solenoid 122c that operates the movable piece 122b of the second starting hole 122, a large prize opening solenoid 128c that operates the movable piece 128b that opens and closes the large prize opening 128, and a movable member drive solenoid 142c that moves the movable member 142 provided within the large prize opening 128, and the main control board 300 is configured to control the opening and closing of the second starting hole 122, the large prize opening 128 and the specific area 140b.

[0053] Furthermore, the first special pattern display device 160, the second special pattern display device 162, the first special pattern reserved indicator device 164, the second special pattern reserved indicator device 166, the normal pattern display device 168, the normal pattern reserved indicator device 170, and the right hit notification indicator device 172 are connected to the main control board 300, and the display of each of these indicators is controlled by the main control board 300.

[0054] In addition, the gaming machine 100 is provided with multiple abnormality detection sensors 174 that detect possible abnormalities or fraud, such as a radio wave detection sensor that detects radio waves, a magnetic detection sensor that detects magnetism, and a door open sensor that detects the open state of the middle frame 104 or the front frame 106, and is configured so that an abnormality detection signal is input from each abnormality detection sensor 174 to the main control board 300.

[0055] Furthermore, a setting change switch 180s is provided on the back of the game board 108. The setting change switch 180s is configured to be accessible by a dedicated key. When the setting change switch 180s is turned on, the operation of changing and checking the setting value becomes possible. Note that the gaming machine 100 has a function of storing any of the setting values ​​with different degrees of advantage as a registered setting value in a setting value buffer, and the game progresses according to the stored registered setting value. However, in the embodiment, a case where only a setting value of 1 (registered setting value = 1) is provided as a setting value is shown.

[0056] A RAM clear button is provided on the back of the game board 108 so that it can be pressed, and pressing of this RAM clear button is detected by a RAM clear switch 182s. The RAM clear switch 182s is connected to the main control board 300, and a RAM clear operation signal is input from the RAM clear switch 182s to the main control board 300. When the RAM clear operation signal is input from the RAM clear switch 182s at power-on, the main CPU 300a clears the main RAM 300c.

[0057] A performance display monitor 184 is provided on the back of the game board 108. The main control board 300 causes the performance display monitor 184 to display the registered setting values ​​and the base ratio.

[0058] In addition, a dispensing control board 310 and a sub-control board 330 are connected to the main control board 300.

[0059] The payout control board 310 performs control for launching game balls and control for paying out prize balls. This payout control board 310 also has a CPU, ROM, and RAM, and is connected to the main control board 300 so as to be able to communicate in both directions. This payout control board 310 is connected to a game information output terminal board 312, and various information on the progress of the game output from the main control board 300 is output to the hall computer of the gaming establishment via the payout control board 310 and the game information output terminal board 312.

[0060] A payout motor 314 is connected to the payout control board 310 to pay out the game balls stored in the storage section to the player as prize balls. The payout control board 310 controls the payout motor 314 based on a payout number designation command sent from the main control board 300 to control the payout motor 314 to pay out a predetermined number of prize balls to the player. At this time, the number of paid out game balls is detected by a payout ball count switch 316s, and it is possible to know whether the prize balls to be paid out have been paid out to the player.

[0061] In addition, a tray full detection switch 318s that detects the full state of the lower tray 134 is connected to the payout control board 310. This tray full detection switch 318s is provided in a passage that leads the game balls paid out as prize balls to the lower tray 134, and a game ball detection signal is input to the payout control board 310 every time a game ball passes through the passage.

[0062] Then, when a predetermined amount or more of game balls are stored in the lower tray 134 and the tray is in a full state, game balls are retained in the passage leading to the lower tray 134, and game ball detection signals are continuously input from the tray full detection switch 318s to the payout control board 310. When the payout control board 310 receives the game ball detection signals continuously for a predetermined time, it determines that the lower tray 134 is in a full state, and transmits a tray full command to the main control board 300. On the other hand, when the continuous input of the game ball detection signals is interrupted after transmitting the tray full command, it determines that the full state has been released, and transmits a tray full release command to the main control board 300.

[0063] In addition, the launch control circuit 320 is connected to the payout control board 310 so as to be able to communicate in both directions. When the launch control circuit 320 receives launch control data from the payout control board 310, it authorizes launch. To the launch control circuit 320, a touch sensor 112s that is provided on the operating handle 112 and detects that the player has touched the operating handle 112, and an operation volume 112a that detects the operation angle of the operating handle 112 are connected. When signals are input from the touch sensor 112s and the operation volume 112a, the launch control circuit 320 controls the energization of the launch solenoid 112c provided on the game ball launching device to launch the game ball.

[0064] The sub-control board 330 mainly controls each presentation during gameplay, standby, etc. The sub-control board 330 includes a sub-CPU 330a, a sub-ROM 330b, a sub-RAM 330c, and an RTC 330d, and is connected to the main control board 300 so as to be able to communicate in one direction from the main control board 300 to the sub-control board 330. The sub-CPU 330a reads out a program stored in the sub-ROM 330b and performs arithmetic processing based on commands transmitted from the main control board 300 and input signals from a timer, and also controls the execution of presentations. At this time, the sub-RAM 330c functions as a work area for data during arithmetic processing by the sub-CPU 330a.

[0065] Specifically, the sub-control board 330 performs image display control to display images on the main performance display unit 200a. A large number of various image data to be displayed on the main performance display unit 200a are stored in the sub-ROM 330b, and the sub-CPU 330a reads the image data from the sub-ROM 330b to a VRAM (not shown) and controls the image display on the main performance display unit 200a.

[0066] The sub-control board 330 also controls the movement of the stage prop device 202 and the lighting of the stage lighting device 204, and also controls the audio output to output audio from the audio output device 206. Furthermore, when an operation detection signal is input from the stage button detection switch 208s that detects that the stage button 208 has been pressed, a predetermined stage is executed.

[0067] Each board is connected to a power supply board (not shown), and power is supplied to each board from a commercial power source via the power supply board. A backup power supply consisting of a capacitor is also provided on the power supply board. The RTC 330d provided on the sub-control board 330 receives power from the backup power supply and keeps track of the current time.

[0068] Fig. 6 is an address map of the memory area used by the main CPU 300a. In Fig. 6, addresses are shown in hexadecimal, with "H" indicating a hexadecimal number. As shown in Fig. 6, the memory area used by the main CPU 300a includes a memory area (0000H to 2FFFH) allocated to the main ROM 300b and a memory area (F000H to F3FFH) allocated to the main RAM 300c.

[0069] The memory area of ​​the main ROM 300b is provided with a used area (0000H to 1A7AH) for storing programs and data for controlling the progress of the game, and a non-used area (2000H to 2BFFH) which is an area other than the used area and stores programs and data for executing processes for conducting tests stipulated in the gaming machine regulations and processes for displaying the performance display monitor 184 (including processes for calculating the base ratio to be displayed on the performance display monitor 184).

[0070] The used area of ​​the main ROM 300b includes a program area (0000H-0A89H) in which a program for controlling the progress of a game is stored, an unused area (0A8AH-0FFFH), and a data area (1000H-1A7AH) in which data other than the program is stored. Note that the used area may not include the unused area (0A8AH-0FFFH).

[0071] The unused area of ​​the main ROM 300b includes a program area (2000H to 27FFH) in which programs for executing processes for performing tests stipulated by gaming machine regulations and processes for displaying the performance display monitor 184 are stored, and a data area (2800H to 2BFFH) in which data other than these programs are stored.

[0072] In addition to the used area and unused area, the memory area of ​​the main ROM 300b also includes an unused area (1A7BH to 1DFFH), a ROM comment area (1E00H to 1EFFH) in which arbitrary data such as the program title and version is stored, an unused area (1F00H to 1FFFH), an unused area (2C00H to 2FBFH), and a program management area (2FC0H to 2FFFH) in which information necessary for the main CPU 300a to execute a program is stored.

[0073] The memory area of ​​the main RAM 300c is divided into a used area (F000H to F1FFH) that is temporarily used when a program for controlling the progress of the game is being executed, and a non-used area (F210H to F228H) that is an area other than the used area and is temporarily used when a program for performing processes for performing tests defined by the gaming machine regulations or for displaying the performance display monitor 184 is being executed.

[0074] The used area of ​​the main RAM 300c includes a work area (F000H-F12AH) that is temporarily used when a program for controlling the progress of a game is being executed, an unused area (F12BH-F1D7H), and a stack area (F1D8H-F1FFH) for temporarily saving data during execution of a program for controlling the progress of a game. The used area may not include the unused area (F12BH-F1D7H).

[0075] The unused area of ​​the main RAM 300c includes a work area (F210H to F21FH) that is temporarily used when programs for processing tests stipulated in the gaming machine regulations and processing for displaying the performance display monitor 184 are being executed, and a stack area (F220H to F228H) in which data is temporarily saved when these programs are being executed.

[0076] In addition to the used area and unused area, the memory area of ​​the main RAM 300c also includes an unused area (F200H to F20FH) and an unused area (F229H to F3FFH).

[0077] In this way, the main ROM 300b and the main RAM 300c are provided with separate areas: a used area used to control the progress of the game, and a non-used area used to execute processes for conducting tests defined by the gaming machine regulations and for controlling the display of the performance display monitor 184.

[0078] In the main RAM 300c, a 16-byte unused area (F200H-F20FH) is provided between the used area and the unused area. This unused area (F200H-F20FH) is set as a boundary area that separates the used area and the unused area, making the boundary between the used area and the unused area clear, and prevents the unused area from being used when a program for controlling the progress of a game is being executed, and prevents the used area from being used when a program for performing a process for performing a test specified by the gaming machine rules or a process for controlling the display of the performance display monitor 184 is being executed.

[0079] The unused area between the used area and the unused area only needs to be at least 1 byte, and from the viewpoint of preventing fraud, it is preferable that it is 4 bytes or more, and more preferably set to 16 bytes or more. Furthermore, writing and reading of data into the unused area is prohibited, but from the viewpoint of preventing fraud, it may be cleared at a predetermined timing.

[0080] Next, a game in the gaming machine 100 will be described together with various tables stored in the main ROM 300b.

[0081] As described above, the gaming machine 100 allows two types of games, special games and normal games, to proceed in parallel, and when these two games are being played, the game proceeds in either a non-time-saving game state or a time-saving game state.

[0082] Although the details of each game state will be described later, the non-time-saving game state is a game state in which the movable piece 122b is less likely to be in the open state and a game ball is less likely to enter the second start hole 122, and the time-saving game state is a game state in which the movable piece 122b is more likely to be in the open state than in the non-time-saving game state and a game ball is more likely to enter the second start hole 122. The initial state of the gaming machine 100 is set to the non-time-saving game state.

[0083] When the player operates the operating handle 112 to launch a game ball into the game area 116 and the game ball flowing down the game area 116 enters the first start hole 120 or the second start hole 122, a lottery is held to determine whether or not the player will receive a game profit (hereinafter, referred to as a "big prize lottery"). If a small prize is won in this big prize lottery, the big prize hole 128 is opened and a small prize game is played.

[0084] Although the details will be described later, when a game ball enters the first start hole 120 or the second start hole 122, various random numbers related to the big role lottery (small win determination random number, winning pattern random number, reach group determination random number, reach mode determination random number, and variable pattern random number) are obtained, and each of these random numbers is stored in the special chart reservation memory area of ​​the main RAM 300c. Hereinafter, the various random numbers stored in the special chart reservation memory area when a game ball enters the first start hole 120 are collectively referred to as special 1 reservation, and the various random numbers stored in the special chart reservation memory area when a game ball enters the second start hole 122 are collectively referred to as special 2 reservation.

[0085] The special chart reservation memory area of ​​the main RAM 300c includes a first special chart reservation memory area and a second special chart reservation memory area. The first special chart reservation memory area has four memory sections (first to fourth memory sections). When a game ball enters the first starting hole 120, the special 1 reservation is stored in order from the first memory section of the first special chart reservation memory area.

[0086] For example, when a game ball enters the first starting hole 120, if no reservation is stored in any of the first storage section to the fourth storage section of the first special chart reservation storage area, the special 1 reservation is stored in the first storage section. Also, for example, when the special 1 reservation is stored in the first storage section to the third storage section, if a game ball enters the first starting hole 120, the special 1 reservation is stored in the fourth storage section.

[0087] The second special chart reservation memory area has one memory section (first memory section). When a game ball enters the second starting hole 122, the special 2 reservation is stored in the second memory section of the second special chart reservation memory area. For example, when a game ball enters the second starting hole 122, if a reservation is not stored in the first memory section of the second special chart reservation memory area, the special 2 reservation is stored in the first memory section.

[0088] The number of special 1 reservations (X1) that can be stored in the first special chart reservation memory area is set to 4. Therefore, for example, when a game ball enters the first starting hole 120, if four special 1 reservations are already stored in the first special chart reservation memory area, the entry of the game ball into the first starting hole 120 will not cause a new special 1 reservation to be stored.

[0089] In addition, the number of special 2 reservations (X2) that can be stored in the second special chart reservation memory area is set to 1. Therefore, for example, when a game ball enters the second starting hole 122, if one special 2 reservation is already stored in the second special chart reservation memory area, the entry of the game ball into the second starting hole 122 will not cause a new special 2 reservation to be stored. However, the number of special 2 reservations (X2) that can be stored in the second special chart reservation memory area may be set to 4.

[0090] FIG. 7(a) is a diagram explaining the small win determination random number judgment table for special 1. Also, FIG. 7(b) is a diagram explaining the small win determination random number judgment table for special 2. When a game ball enters the first start hole 120 or the second start hole 122, one small win determination random number is obtained within the range of 0 to 65535. Then, a small win determination random number judgment table is selected according to the reserved type read out when starting the big role lottery, and the big role lottery is performed using the selected small win determination random number judgment table and the acquired small win determination random number.

[0091] During the game, the big role lottery is performed by referring to the special 1 small win determination random number judgment table or special 2 small win determination random number judgment table corresponding to the currently set setting value (registered setting value stored in the setting value buffer). As described above, in the embodiment, the case where only the setting value = 1 (registered setting value = 1) is provided as the setting value is shown.

[0092] Specifically, when starting the big role lottery for the special 1 reservation, the big role lottery is performed by referring to the special 1 small win determination random number judgment table shown in Figure 7 (a). According to this special 1 small win determination random number judgment table, if the small win determination random number is 20001 to 20329, it is judged as a small win, and if it is any other small win determination random number, it is judged as a miss. Therefore, the small win probability in this case is about 1 / 199.20.

[0093] In addition, when starting the big role lottery for the special 2 reservation, the special 2 small win determination random number judgment table shown in Figure 7 (b) is referenced to perform the big role lottery. According to this special 2 small win determination random number judgment table, if the small win determination random number is 20001 to 21850, it is judged as a small win, and if it is any other small win determination random number, it is judged as a miss. Therefore, in this case, the small win probability is about 1 / 35.42.

[0094] 8 is a diagram explaining the winning symbol random number judgment table. When a game ball enters the first start hole 120 or the second start hole 122, one winning symbol random number is obtained within the range of 0 to 99. When the judgment result of "small win" is derived by the big role lottery, the type of special symbol is determined by the obtained winning symbol random number and the winning symbol random number judgment table.

[0095] At this time, if the "small win" is won by the special 1 reservation, the special 1 winning pattern random number determination table is selected as shown in Figure 8 (a). Also, if the "small win" is won by the special 2 reservation, the special 2 winning pattern random number determination table is selected as shown in Figure 8 (b). In the following, the special pattern determined by the winning pattern random number, that is, the special pattern determined when the small win determination result is obtained, is called the small win pattern, and the special pattern determined when the loss determination result is obtained is called the loss pattern.

[0096] According to the special 1 winning pattern random number determination table shown in FIG. 8(a) and the special 2 winning pattern random number determination table shown in FIG. 8(b), the type of special pattern (small winning pattern) is determined according to the value of the obtained winning pattern random number, as shown in the figure.

[0097] On the other hand, when the result of the big role lottery is "miss", if the result of the lottery is derived by special 1 reservation, the special pattern X is determined as the losing pattern without drawing. Also, when the result of the big role lottery is "miss", if the result of the lottery is derived by special 2 reservation, the special pattern Y is determined as the losing pattern without drawing.

[0098] In other words, the winning symbol random number determination table is referenced only when the big role lottery result is a "small win", and is not referenced when the big role lottery result is a "miss". In this case, different small win symbols are determined in the special 1 winning symbol random number determination table and the special 2 winning symbol random number determination table. However, the same small win symbol may be determined in both tables, or the type of special symbol (small win symbol) may be determined by referring to the winning symbol random number determination table 1 regardless of the reserved type.

[0099] FIG. 9 is a diagram for explaining the reach group determination random number judgment table. A plurality of reach group determination random number judgment tables are provided, and a preset table is selected according to the reserved type, reserved number, game state, and the variable state associated with the game state. When a game ball enters the first start hole 120 or the second start hole 122, one reach group determination random number is acquired from the range of 0 to 10006. As described above, when the big role lottery result is derived, a process is performed to determine a variable performance pattern (variation mode number, variable pattern number) that notifies the big role lottery result. In the embodiment, when the big role lottery result is "miss", in determining the variable performance pattern, first, the group type is determined by the reach group determination random number and the reach group determination random number judgment table. Note that the variable state is a concept that specifies which table is to be referenced to determine the variable performance pattern, and is set separately from the game state.

[0100] For example, when the game state is set to the non-time-saving game state, if the "miss" big role lottery result is derived based on the special 1 reservation, and the number of reserved special 1s (hereinafter simply referred to as the "reserved number") when the big role lottery is performed is 0, the reach group determination random number judgment table 1 is selected as shown in FIG. 9(a). Similarly, when the game state is set to the non-time-saving game state, if the "miss" big role lottery result is derived based on the special 1 reservation, and the number of reserved special roles when the big role lottery is performed is 1, the reach group determination random number judgment table 2 is selected as shown in FIG. 9(b), and if the number of reserved special roles is 2 to 3, the reach group determination random number judgment table 3 is selected as shown in FIG. 9(c). In FIG. 9, the group x written in the group type column indicates an arbitrary group number. Therefore, various group numbers are determined as the group type according to the acquired reach group determination random number and the type of the reach group determination random number judgment table to be referred to.

[0101] Here, we have explained the reach group determination random number judgment table that is referenced when a "miss" major role lottery result is derived based on the special 1 reservation in a non-time-saving game state, but many other reach group determination random number judgment tables are stored in the main ROM 300b.

[0102] In addition, if the result of the big role lottery is a "small win", the group type is not determined when determining the variable performance pattern. In other words, the reach group determination random number judgment table is referenced only when the result of the big role lottery is a "miss", and is not referenced when the result of the big role lottery is a "small win".

[0103] Fig. 10 is a diagram explaining the reach mode determination random number judgment table. This reach mode determination random number judgment table is roughly divided into a reach mode determination random number judgment table at the time of a miss, which is selected when the big role lottery result is "miss", and a reach mode determination random number judgment table at the time of a small win, which is selected when the big role lottery result is "small win". The reach mode determination random number judgment table at the time of a miss is provided for each group type determined as described above, and the reach mode determination random number judgment table at the time of a small win is provided for each reserved type.

[0104] In addition, each reach mode determination random number judgment table is also provided for each game state and type of symbol. Here, an example of a reach mode determination random number judgment table for group x when it is lost, which is referred to in a specific game state and type of symbol, is shown in Figure 10(a), an example of a reach mode determination random number judgment table for special 1 when it is a small win is shown in Figure 10(b), and an example of a reach mode determination random number judgment table for special 2 when it is a small win is shown in Figure 10(c).

[0105] When a game ball enters the first start hole 120 or the second start hole 122, one reach mode determination random number is obtained from the range of 0 to 250. If the result of the big role lottery is a "lose", as shown in Fig. 10(a), a reach mode determination random number judgment table at the time of a miss corresponding to the group type determined by the lottery of the group type is selected, and a variable mode number is determined based on the selected reach mode determination random number judgment table at the time of a miss and the reach mode determination random number.

[0106] Furthermore, if the result of the big prize lottery is a "small win," then as shown in Figures 10(b) and (c), a random number judgment table for determining the reach mode at the time of a small win corresponding to the read-out hold type is selected, and a variable mode number is determined based on the selected random number judgment table for determining the reach mode at the time of a small win and the reach mode determination random number.

[0107] In addition, in each reach mode determination random number judgment table, the reach mode determination random number is associated with a fluctuation pattern random number judgment table described later together with the fluctuation mode number, and the fluctuation pattern random number judgment table is determined at the same time as the fluctuation mode number is determined. In addition, in FIG. 10, table x described in the column of the fluctuation pattern random number judgment table indicates an arbitrary table number. Therefore, the fluctuation mode number and the table number of the fluctuation pattern random number judgment table are determined according to the acquired reach group determination random number and the type of the reach mode determination random number judgment table to be referred to. In addition, in the embodiment, the fluctuation mode number and the fluctuation pattern number described later are set in hexadecimal. In the following, "H" is added when indicating a hexadecimal number, but ○○H described in FIG. 10 to FIG. 12 indicates an arbitrary value indicated in hexadecimal.

[0108] As described above, when the big role lottery result is "miss", the group type is first determined by the reach group determination random number judgment table and reach group determination random number shown in Fig. 9. Then, according to the determined group type and the game state, the fluctuation mode number and the fluctuation pattern random number judgment table are determined by the reach mode determination random number judgment table at the time of miss and the reach mode determination random number shown in Fig. 10(a).

[0109] On the other hand, if the result of the big prize lottery is a "small prize," the small prize reach mode determination random number judgment table shown in Figure 10, which corresponds to the determined small prize pattern (type of special pattern), is referenced, and the reach mode determination random number is used to determine the fluctuation mode number and fluctuation pattern random number judgment table.

[0110] 11 is a diagram for explaining the fluctuation pattern random number determination table. Here, the fluctuation pattern random number determination table x of a predetermined table number x is shown, but in addition, many other fluctuation pattern random number determination tables are provided for each table number.

[0111] When a game ball enters the first start hole 120 or the second start hole 122, one fluctuation pattern random number is obtained from the range of 0 to 238. Then, based on the fluctuation pattern random number determination table determined at the same time as the above fluctuation mode number and the obtained fluctuation pattern random number, a fluctuation pattern number is determined as shown in the figure.

[0112] In this way, when the big role lottery is performed, the change mode number and the change pattern number are determined according to the big role lottery result, the determined symbol type, the game state, the reserved number, the reserved type, etc. These change mode numbers and change pattern numbers specify the change performance pattern, and each of them is associated with the mode and time of the change performance.

[0113] Fig. 12 is a diagram for explaining a variation time determination table. As described above, when the variation mode number is determined, the variation time 1 is determined according to the variation time 1 determination table shown in Fig. 12(a). According to this variation time 1 determination table, the variation time 1 is associated with each variation mode number, and the corresponding variation time 1 is determined according to the determined variation mode number.

[0114] In addition, as described above, when the variation pattern number is determined, the variation time 2 is determined according to the variation time 2 determination table shown in Fig. 12(b). According to this variation time 2 determination table, the variation time 2 is associated with each variation pattern number, and the corresponding variation time 2 is determined according to the determined variation pattern number. The total time of the variation times 1 and 2 determined in this way is the time of the variation performance that notifies the big role lottery result, that is, the variation time.

[0115] When the variation mode number is determined as described above, a variation mode command corresponding to the determined variation mode number is sent to the sub-control board 330, and when the variation pattern number is determined, a variation pattern command corresponding to the determined variation pattern number is sent to the sub-control board 330. In the sub-control board 330, the first half of the variation performance is mainly determined based on the received variation mode command, and the second half of the variation performance is mainly determined based on the received variation pattern command, but the details will be described later. In the following, the variation mode number and the variation pattern number are collectively referred to as variation information, and the variation mode command and the variation pattern command are collectively referred to as variation command.

[0116] 13 is a diagram explaining the special electric accessory operation ram set table. The special electric accessory operation ram set table stores various data for controlling the small win game and the big win game, and during the small win game and the big win game, the big win port solenoid 128c is controlled to be energized by referring to the special electric accessory operation ram set table.

[0117] According to the special electric role operation RAM set table, the opening time (waiting time until the first round play starts), the maximum number of times the special electric role operates (the number of round plays executed during one small win play or one big role play), the number of times the special electric role opens and closes (the number of times the large prize opening 128 opens during one round play), the solenoid energizing time (the energizing time of the large prize opening solenoid 128c for each opening of the large prize opening 128, i.e., the opening time of one large prize opening 128), the prescribed number (the maximum number of wins that can be won into the large prize opening 128 in one round play), the effective time for closing the large prize opening (the closing time of the large prize opening 128 between round plays, i.e., the interval time between rounds), and the ending time (the waiting time from the end of the last round play until the normal special play is resumed) are pre-stored as control data for the big role play as shown in the figure.

[0118] In the embodiment, when the special symbols Z1 to Z4, which are the small prize symbols, are determined, a small prize game consisting of one round of play is first executed. In this small prize game, the opening and closing of the large prize opening 128 is repeatedly executed. Specifically, the large prize opening 128 is controlled to open for 0.1 seconds (open 1), close for 3.0 seconds (close 1), open for 0.1 seconds (open 2), close for 1.0 seconds (close 2), open for 0.1 seconds (open 3), close for 1.0 seconds (close 3), and open for 0.1 seconds (open 4). As described above, in the embodiment, in the small prize game executed when the special symbols Z1 to Z4 are determined, the large prize opening 128 is opened a maximum of four times in the first round, but is not limited to this. For example, the large prize opening 128 may be opened a maximum of ten times in the first round.

[0119] Here, a specific area 140b and a non-specific area 140c are provided inside the big prize opening 128, and a game ball that enters the big prize opening 128 always enters the specific area 140b or the non-specific area 140c. In the small prize game, if the game ball that enters the big prize opening 128 enters the specific area 140b, a big prize game in which the big prize opening 128 is opened is executed following the small prize game.

[0120] In addition, in a small prize game that is executed when the special symbols Z1 to Z2 are determined, if the game ball that entered the big prize opening 128 enters the specific area 140b, a big prize game is executed following the small prize game, and in this big prize game, a round game is executed three times (2R to 4R). In addition, in a small prize game that is executed when the special symbol Z3 is determined, if the game ball that entered the big prize opening 128 enters the specific area 140b, a big prize game is executed following the small prize game, and in this big prize game, a round game is executed twice (2R to 3R). In addition, in the small prize game that is executed when the special pattern Z4 is determined, if the game ball that entered the big prize opening 128 enters the specific area 140b, the small prize game is followed by a big prize game, in which nine rounds (2R to 10R) are played.

[0121] Fig. 14 is a diagram illustrating the opening and closing manner of the large prize opening 128 and the opening and closing manner of the specific area 140b by the movable member 142. As shown in Fig. 14, in a small prize game in which the large prize opening 128 is opened, the movable member 142 opens the specific area 140b for an instant (about 0.1 seconds) at the same time as the large prize opening 128 is opened, and then maintains the specific area 140b in a closed state for a predetermined time, and then maintains the specific area 140b in an open state again.

[0122] Specifically, as shown in FIG. 14, when the special symbols Z1 to Z4 are determined and the small prize game is executed, the large prize opening 128 is opened a total of four times in the small prize game. Therefore, the game ball that enters the large prize opening 128 at the same time as the first opening of the large prize opening 128 may not be able to enter the specific area 140b, but the game ball that enters the large prize opening 128 at the second or subsequent opening of the large prize opening 128 can certainly enter the specific area 140b. Although a detailed explanation is omitted, a structure that decelerates the game ball rolling on the large prize opening 128 is provided above the large prize opening 128, and if the game ball is appropriately launched into the second game area 116b from the start of the small prize game, the game ball will definitely enter the specific area 140b.

[0123] In addition, if an unforeseen event occurs, such as the game ball getting stuck in the big prize opening 128, or the game ball getting stuck in the big prize opening 128 for a long time for some reason, the game ball may not enter the specific area 140b in the small prize game. Therefore, in this specification, for ease of understanding, the words "always" and "certainly" are used, but this is on the premise that the state of the gaming machine 100 is in an appropriate state for playing the game and no unforeseen event has occurred, and does not mean 100% physically.

[0124] 15 is a diagram explaining a game state setting table for setting the game state after the end of the big prize game. When a two-type big prize is won in the small prize game as described above, the game state is set according to the type of the special symbol that was won and the game state at the time of the win.

[0125] Here, in the embodiment, a non-time-saving game state and a time-saving game state are provided as game states. The non-time-saving game state is the initial state of the gaming machine 100, and the time-saving game state is a state in which the second start opening 122 is easier to open than the non-time-saving game state. That is, an opening condition for opening the second start opening 122 is set in each game state, and an opening condition for opening the second start opening 122 is set in the time-saving game state, which is easier to open than the non-time-saving game state.

[0126] In addition, when the game state after the big role game is set to the time-saving game state, the time-saving end condition for ending the time-saving game state is also set. Here, the time-saving end condition includes the number of times of time-saving, the number of times of time-saving end operation for small win (Z3), and the number of times of time-saving end operation for small win (Z4).

[0127] Here, in the embodiment, when the game state is set to the time-saving game state, the time-saving end condition is set, but different time-saving end conditions are set for the common time-saving game state depending on the type of special symbol and the game state at the time of winning the small prize. In the following, the time-saving game state is explained by distinguishing it into three modes: the upper mode, the first lower mode, and the second lower mode.

[0128] These three modes all have the same probability of winning a small prize and the opening condition of the second starting hole 122, but the time-saving end condition is different from each other. In the embodiment, the higher mode is more advantageous to the player because the time-saving end condition is less likely to be satisfied than the first lower mode and the second lower mode. Also, as will be described in detail later, the first lower mode does not transition directly to the higher mode, but the second lower mode can transition directly to the higher mode, so the second lower mode is more advantageous to the player than the first lower mode.

[0129] The number of time-saving times is the number of times that the pattern is changed based on the special 1 reservation or the special 2 reservation. The number of time-saving times is subtracted every time the result of the big role lottery based on the special 1 reservation or the special 2 reservation is confirmed in the time-saving game state, and when the remaining number of time-saving times becomes 0, the game state is changed to the non-time-saving game state. In other words, the number of time-saving times is subtracted when the result of the big role lottery based on the special 1 reservation or the special 2 reservation is confirmed.

[0130] The small win time-saving end operation count (Z3) is the number of times a predetermined small win (specifically, the special pattern Z3) based on the special 2 reservation in the time-saving game state is won, or the number of times the special pattern Z3 is won as the small win pattern and a small win game is executed. The small win time-saving end operation count (Z3) is subtracted every time the special pattern Z3, which is a small win pattern, is determined as a result of the big role lottery based on the special 2 reservation in the time-saving game state, and when the remaining number of the small win time-saving end operation count (Z3) becomes 0, the game state is changed to a non-time-saving game state. In other words, the small win time-saving end operation count (Z3) is subtracted only when the special pattern Z3, which is a small win pattern, is determined as a result of the big role lottery based on the special 2 reservation.

[0131] The small win time-saving end operation count (Z4) is the number of times a predetermined small win (specifically, the special pattern Z4) based on the special 2 reservation in the time-saving game state is won, or the number of times the special pattern Z4 is won as the small win pattern and a small win game is executed. The small win time-saving end operation count (Z4) is subtracted every time the special pattern Z4, which is a small win pattern, is determined as a result of the big role lottery based on the special 2 reservation in the time-saving game state, and when the remaining number of the small win time-saving end operation count (Z4) becomes 0, the game state is changed to a non-time-saving game state. In other words, the small win time-saving end operation count (Z4) is subtracted only when the special pattern Z4, which is a small win pattern, is determined as a result of the big role lottery based on the special 2 reservation.

[0132] When any one of these three time-saving end conditions is satisfied, the time-saving game state ends and the game state transitions to a non-time-saving game state. In addition to the above time-saving end conditions, for example, the number of special 1 time-saving times that is subtracted only when the result of the big role lottery based on the special 1 reservation is confirmed, and the number of special 2 time-saving times that is subtracted only when the result of the big role lottery based on the special 2 reservation is confirmed may be set as time-saving end conditions.

[0133] As shown in FIG. 15, in a small win game that is executed when a small win is won, if a type 2 big win is won, the mode (time-saving end condition) is set as follows based on the game state at the time of the small win and the type of small win pattern.

[0134] That is, when the special symbol Z1 is determined as the small win symbol, regardless of the game state at the time of winning the small win, the game state after the big win is set as the time-saving game state, and the first lower mode is set. As shown in FIG. 15, the time-saving end conditions of the first lower mode are set as follows: the number of time-saving times is 50, the number of times (Z3) for the small win time-saving end operation is 1, and the number of times (Z4) for the small win time-saving end operation is 1.

[0135] In addition, when the special symbol Z2 is determined as the small win symbol, the game state after the big win is set to a non-time-saving game state regardless of the game state at the time of winning the small win.

[0136] In addition, when the special pattern Z3 is determined as the small win pattern and the game state at the time of winning the small win is a non-time-saving game state, the game state after the big win is played is set to the first lower mode as a time-saving game state.

[0137] In addition, when the special symbol Z3 is determined as the small winning symbol and the game state at the time of winning the small winning is the time-saving game state, the game state after the big winning game is set to the time-saving game state and the higher mode is set. As shown in FIG. 15, the time-saving end conditions of the higher mode are set as follows: the number of time-saving times is 100, the number of times of the small winning time-saving end operation (Z3) is 0, and the number of times of the small winning time-saving end operation (Z4) is 0.

[0138] In addition, when the special symbol Z4 is determined as the small win symbol and the game state at the time of winning the small win is a non-time-saving game state, the game state after the big win is set to a time-saving game state and the second lower mode is set. As shown in FIG. 15, the time-saving end conditions of the second lower mode are set as follows: the number of time-saving times is 50, the number of times (Z3) for the small win time-saving end operation is 1, and the number of times (Z4) for the small win time-saving end operation is 0.

[0139] In addition, if the special pattern Z4 is determined as the small win pattern and the game state at the time of winning the small win is a time-saving game state, the game state after the big win is played is set to the time-saving game state, and a higher mode is set.

[0140] In addition, when the small win time-saving end operation count (Z3) is set to 0, the time-saving end condition based on the small win time-saving end operation count (Z3) is not substantially satisfied according to the processing in the main control board 300 described later. The small win time-saving end operation count (Z3) may be set to a sufficiently large number such as 200, or may not be set at all. Even in this case, according to the processing in the main control board 300 described later, the time-saving end condition based on the small win time-saving end operation count (Z3) is not substantially satisfied.

[0141] Also, when the small win time-saving end operation count (Z4) is set to 0, the process in the main control board 300 described later will not actually establish the time-saving end condition based on the small win time-saving end operation count (Z4). The small win time-saving end operation count (Z4) may be set to a sufficiently large number such as 200, or may not be set at all. Even in this case, the process in the main control board 300 described later will not actually establish the time-saving end condition based on the small win time-saving end operation count (Z4).

[0142] In the embodiment, in the first lower mode, when the special symbol Z3 or the special symbol Z4 is won and a small win game is executed, the time-saving game state ends before the start of the small win game, that is, before the large winning opening 128 is opened in the small win game, and the game state transitions to a non-time-saving game state. In addition, in the second lower mode, when the special symbol Z3 is won and a small win game is executed, the time-saving game state ends before the start of the small win game, that is, before the large winning opening 128 is opened in the small win game, and the game state transitions to a non-time-saving game state. As a result, at the time when the small win game is started, the game state is set to a non-time-saving game state. In this way, the prize balls that enter the large winning opening 128 during the small win game and are paid out are not treated as prize balls during the time-saving game state, and it is possible to suppress a situation in which the number of game balls increases during the time-saving game state.

[0143] 16 is a diagram explaining a winning decision random number judgment table. When the game ball flowing down the game area 116 passes through the gate 124, a normal symbol judgment process (hereinafter referred to as "normal symbol lottery") is performed, which corresponds to whether or not to control the movable piece 122b of the second starting hole 122 to be energized.

[0144] Although the details will be described later, when the game ball passes through the gate 124, one winning determination random number is obtained from the range of 0 to 99, and this random number value is stored in the general map reserve memory area of ​​the main RAM 300c, up to a maximum of four. In other words, the general map reserve memory area has four storage units for saving winning determination random numbers. Therefore, if a game ball passes through the gate 124 with winning determination random numbers stored in all four storage units of the general map reserve memory area, no winning determination random number will be stored based on the passage of the game ball. Hereinafter, the winning determination random number stored in the general map reserve memory area after the game ball passes through the gate 124 will be referred to as a general map reserve.

[0145] When starting the normal symbol lottery in the non-time-saving game state, as shown in FIG. 16(a), the winning symbol determination random number judgment table for the non-time-saving game state is referenced. According to this winning symbol determination random number judgment table for the non-time-saving game state, when the winning symbol determination random number is 0, a winning symbol is determined as the type of normal symbol, and when the winning symbol determination random number is 1 to 99, a losing symbol is determined as the type of normal symbol. Therefore, the probability that a winning symbol is determined in the non-time-saving game state, that is, the probability of winning, is 1 / 100. As will be described in detail later, when a winning symbol is determined in this normal symbol lottery, the second start hole 122 is controlled to be in an open state, and when a losing symbol is determined, the second start hole 122 is maintained in a closed state.

[0146] In addition, when starting a normal symbol lottery in the time-saving game state, a time-saving game state winning random number determination table is referenced as shown in Fig. 16(b). According to this time-saving game state winning random number determination table, when the winning random number is 0 to 98, a winning symbol is determined as the type of normal symbol, and when the winning random number is 99, a losing symbol is determined as the type of normal symbol. Therefore, the probability that a winning symbol is determined in the time-saving game state, that is, the probability of winning, is 99 / 100.

[0147] FIG. 17(a) is a diagram for explaining the normal pattern variation time data table, and FIG. 17(b) is a diagram for explaining the opening / closing control pattern table. As described above, when the normal pattern lottery is performed, the variation time of the normal pattern is determined. The normal pattern variation time data table is referenced when determining the variation time of the normal pattern when a winning pattern or a losing pattern is determined by the normal pattern lottery. According to this normal pattern variation time data table, when the game state is set to a non-time-saving game state, the variation time is determined to be 10 seconds, and when the game state is set to a time-saving game state, the variation time is determined to be 1 second. When the variation time is determined in this way, the normal pattern display 168 is displayed (blinking) for the determined time. Then, when a winning pattern is determined, the normal pattern display 168 is turned on, and when a losing pattern is determined, the normal pattern display 168 is turned off.

[0148] Then, when the winning symbol is determined by the normal symbol lottery and the normal symbol display 168 is lit, the movable piece 122b of the second starting hole 122 is controlled to energize by referring to the opening / closing control pattern table as shown in Fig. 17(b). Note that, in reality, an opening / closing control pattern table is provided for each game state, and depending on the game state when the normal symbol is determined, the corresponding table is set at the start of energization of the normal electric role solenoid 122c, but here, for convenience of explanation, the control data corresponding to each game state is shown in one table.

[0149] When the winning symbol is determined, as shown in FIG. 17(b), the opening and closing of the second starting hole 122 is controlled by referring to the opening and closing control pattern table. According to this opening / closing control pattern table, the time before normal power is released (waiting time until the second start port 122 starts to open), the maximum number of times the normal electric role can be switched between opening and closing (the number of times the second start port 122 is opened), the solenoid power supply time (the power supply time of the normal electric role solenoid 122c for each number of times the second start port 122 is opened, i.e., the opening time of one second start port 122), the specified number (the maximum number of winnings that can be won into the second start port 122 while the second start port 122 is fully open), the normal power closing effective time (the closing time between each opening of the second start port 122, i.e., the pause time), the normal power active state time (waiting time from the end of the last opening of the second start port 122), and the normal power end wait time (waiting time until the variable display of the normal pattern described below is resumed after the normal power active state time has elapsed) are pre-stored as control data for the second start port 122 for each game state, as shown in the figure.

[0150] In this way, the non-time-saving game state and the time-saving game state are respectively associated with the opening / closing control conditions for opening / closing the second start port 122 as game progress conditions, and in the time-saving game state, it is easier for the game ball to enter the second start port 122 than in the non-time-saving game state. In other words, in the time-saving game state, as long as the game ball passes through the gate 124, regular lotteries are performed one after another, and the second start port 122 is frequently in an open state, so that the player can perform the big role lottery while reducing the consumption of game balls.

[0151] The opening and closing conditions of the second start opening 122 prescribe three elements: the probability of winning a normal pattern, the time for the variable display of the normal pattern, and the opening time of the second start opening 122. In the embodiment, two of these elements are set to be more advantageous for the time-saving game state than for the non-time-saving game state, so that the game ball is more likely to enter the second start opening 122 in the time-saving game state than in the non-time-saving game state. However, one or three of the above three elements may be set to be more advantageous for the time-saving game state than the non-time-saving game state. In any case, it is sufficient that the time-saving game state is more advantageous than the non-time-saving game state in at least one element, so that the game ball is more likely to enter the second start opening 122 overall in the time-saving game state than in the non-time-saving game state. In other words, when the game state is set to a non-time-saving game state, the movable piece 122b is controlled to open and close in accordance with a first condition, and when the game state is set to a time-saving game state, the movable piece 122b is controlled to open and close in accordance with a second condition which is more likely to be in the open state than the first condition.

[0152] FIG. 18 is a diagram for explaining the game characteristics according to the embodiment. In the following, the case where the player appropriately launches the game ball and the game progresses in accordance with the original game characteristics, that is, the case where the game continues normally, will be mainly explained, and the case where an irregular situation occurs will basically be omitted. Note that the case where the game continues normally refers to the case where the player plays the game in accordance with the original game characteristics, and indicates the case where irregular situations such as various errors and game stoppages do not occur.

[0153] The initial state of the gaming machine 100 is the non-time-saving gaming state, and the player starts playing in the non-time-saving gaming state, as shown in (1) of FIG. 18. In the non-time-saving gaming state, the second start hole 122 is hardly opened, so the player performs a so-called left shot to shoot the gaming ball toward the first gaming area 116a, and the gaming ball enters the first start hole 120. In other words, the reserve that is the main target for variation (hereinafter referred to as the target reserve) is set to the special 1 reserve. Therefore, in the non-time-saving gaming state, the player plays the game while hoping to win a small prize by the special 1 reserve. In addition, in the non-time-saving gaming state, the probability of winning a small prize based on the special 1 reserve is set to about 1 / 199.20.

[0154] In the non-time-saving game state, when a small win is won by the special 1 reservation, the special symbol Z1 is determined as the small win symbol with a probability of 50%, and a small win game based on the special symbol Z1 is executed. In this small win game, since the game ball can enter the specific area 140b, the big role game is executed following the small win game. At this time, in the embodiment, the player can get a total of 600 prize balls in the small win game and the big role game. And, since the game state at the time of winning is the non-time-saving game state, as shown in (2) of FIG. 18, the game state after the big role game is set to the first lower mode as the time-saving game state.

[0155] In addition, in the non-time-saving game state, when a small win is won by the special 1 reservation, the special symbol Z2 is determined as the small win symbol with a probability of 50%, and a small win game based on the special symbol Z2 is executed. In this small win game, since the game ball can enter the specific area 140b, the big role game is executed following the small win game. At this time, in the embodiment, the player can get a total of 600 prize balls in the small win game and the big role game. And, since the game state at the time of winning is the non-time-saving game state, the game state after the big role game is reset to the non-time-saving game state as shown in (1) of FIG. 18.

[0156] In the first lower mode, the second start port 122 is frequently opened by passing the game ball through the gate 124. Since the gate 124 and the second start port 122 are provided in the second game area 116b, the player performs a so-called right hit to make the game ball flow down to the second game area 116b, and makes the game ball enter the second start port 122. In other words, in the first lower mode in which the target reservation is set to the special 2 reservation, the player plays the game while hoping to win a small prize through the special 2 reservation.

[0157] In the first lower mode, the probability of winning a small prize based on the special 2 reservation is set to about 1 / 35.42. In addition, the time-saving end conditions are set as follows: the number of time-saving times is 50, the number of times that the small prize time-saving end operation (Z3) is 1, and the number of times that the small prize time-saving end operation (Z4) is 1.

[0158] In the first lower mode, when a small win is won by the special 2 reservation, the special symbol Z3 is determined with a probability of 50%, and a small win game based on the special symbol Z3 is executed. In this small win game, since the game ball can enter the specific area 140b, a big role game is executed following the small win game. At this time, in the embodiment, the player can obtain a total of 450 prize balls in the small win game and the big role game. Also, when the special symbol Z3 is won in the first lower mode, a time-saving end condition based on the small win time-saving end operation number (Z3) is established. That is, when the special symbol Z3 is won in the first lower mode, the game state at the time of winning becomes a non-time-saving game state. Therefore, as shown in (2) of FIG. 18, the game state after the big role game is reset to the first lower mode as a time-saving game state.

[0159] In addition, in the first lower mode, when a small win is won by the special 2 reservation, the special pattern Z4 is determined with a probability of 50%, and a small win game based on the special pattern Z4 is executed. In this small win game, since the game ball can enter the specific area 140b, a big role game is executed following the small win game. At this time, in the embodiment, the player can obtain a total of 1500 prize balls in the small win game and the big role game. In addition, when the special pattern Z4 is won in the first lower mode, a time-saving end condition based on the small win time-saving end operation number (Z4) is established. That is, when the special pattern Z4 is won in the first lower mode, the game state at the time of winning becomes a non-time-saving game state. Therefore, as shown in (3) of FIG. 18, the game state after the big role game is set to the second lower mode as a time-saving game state.

[0160] In the first lower mode, if no small prize is won in 50 big prize draws, the time-saving end condition based on the number of times the time-saving has been performed is met, the so-called time-saving end occurs, and the game state is set to a non-time-saving game state.

[0161] In the second lower mode, the second start port 122 is frequently opened by passing the game ball through the gate 124. Since the gate 124 and the second start port 122 are provided in the second game area 116b, the player performs a so-called right hit to make the game ball flow down to the second game area 116b, and makes the game ball enter the second start port 122. In other words, in the second lower mode in which the target reservation is set to the special 2 reservation, the player plays the game while hoping to win a small prize through the special 2 reservation.

[0162] In the second lower mode, the probability of winning a small prize based on the special 2 reservation is set to about 1 / 35.42. In addition, the time-saving end conditions are set as follows: the number of times of time-saving is 50, the number of times of time-saving end operation for small prize (Z3) is 1, and the number of times of time-saving end operation for small prize (Z4) is 0. In other words, in the first lower mode and the second lower mode, only the number of times of time-saving end operation for small prize (Z4) is different as the time-saving end condition, and the other conditions (the number of times of time-saving and the number of times of time-saving end operation for small prize (Z3)) are set to the same time-saving end condition.

[0163] In the second lower mode, when a small win is won by the special 2 reservation, the special symbol Z3 is determined with a probability of 50%, and a small win game based on the special symbol Z3 is executed. In the small win game based on the special symbol Z3, since the game ball can enter the specific area 140b, the big role game is executed following the small win game. At this time, in the embodiment, the player can obtain a total of 450 prize balls in the small win game and the big role game. Also, when the special symbol Z3 is won in the second lower mode, the time-saving end condition based on the small win time-saving end operation number (Z3) is established. That is, when the special symbol Z3 is won in the second lower mode, the game state at the time of winning becomes a non-time-saving game state. Therefore, as shown in (2) of FIG. 18, the game state after the big role game is set to the first lower mode as a time-saving game state.

[0164] In addition, in the second lower mode, when a small win is won by the special 2 reservation, the special symbol Z4 is determined with a probability of 50%, and a small win game based on the special symbol Z4 is executed. In the small win game based on the special symbol Z4, since the game ball can enter the specific area 140b, the big role game is executed following the small win game. At this time, in the embodiment, the player can obtain a total of 1500 prize balls in the small win game and the big role game. In addition, when the special symbol Z4 is won in the second lower mode, the time-saving end condition based on the small win time-saving end operation number (Z4) is not established. In other words, when the special symbol Z4 is won in the second lower mode, the game state at the time of winning is a time-saving game state. Therefore, as shown in (4) of FIG. 18, the game state after the big role game is set to the high-order mode as a time-saving game state.

[0165] In the second lower mode, if no small prize is won in 50 big prize draws, the time-saving end condition based on the number of times the time-saving has been performed is met, the so-called time-saving end occurs, and the game state is set to a non-time-saving game state.

[0166] In the higher mode, the second start port 122 is frequently opened by passing the game ball through the gate 124. Since the gate 124 and the second start port 122 are provided in the second game area 116b, the player performs a so-called right hit to make the game ball flow down to the second game area 116b, and makes the game ball enter the second start port 122. In other words, in the higher mode in which the target reservation is set to the special 2 reservation, the player plays the game while hoping to win a small prize through the special 2 reservation.

[0167] In the higher mode, the probability of winning a small prize based on the special 2 reservation is set to about 1 / 35.42. In addition, the time-saving end conditions are set as follows: the number of time-saving times is 100, the number of times that the small prize time-saving end operation (Z3) is 0, and the number of times that the small prize time-saving end operation (Z4) is 0.

[0168] In the higher mode, when a small win is won by the special 2 reservation, the special pattern Z3 is determined with a probability of 50%, and a small win game based on the special pattern Z3 is executed. In the small win game based on the special pattern Z3, since the game ball can enter the specific area 140b, the big role game is executed following the small win game. At this time, in the embodiment, the player can obtain a total of 450 prize balls in the small win game and the big role game. Also, when the special pattern Z3 is won in the higher mode, the time-saving end condition based on the small win time-saving end operation number (Z3) is not established. That is, when the special pattern Z3 is won in the higher mode, the game state at the time of winning becomes a time-saving game state. Therefore, as shown in (4) of FIG. 18, the game state after the big role game is reset to the higher mode as a time-saving game state.

[0169] In addition, in the higher mode, when a small win is won by the special 2 reservation, the special pattern Z4 is determined with a probability of 50%, and a small win game based on the special pattern Z4 is executed. In the small win game based on the special pattern Z4, since the game ball can enter the specific area 140b, the big role game is executed following the small win game. At this time, in the embodiment, the player can obtain a total of 1500 prize balls in the small win game and the big role game. In addition, when the special pattern Z4 is won in the higher mode, the time-saving end condition based on the small win time-saving end operation number (Z4) is not established. In other words, when the special pattern Z4 is won in the higher mode, the game state at the time of winning becomes a time-saving game state. Therefore, as shown in (4) of FIG. 18, the game state after the big role game is reset to the higher mode as a time-saving game state.

[0170] In the higher mode, if no small prize is won in 100 big prize draws, the time-saving end condition based on the number of times the time-saving has been played is met, the so-called time-saving end occurs, and the game state is set to a non-time-saving game state.

[0171] As described above, in the first lower mode, the probability of being reset to the first lower mode after playing a big role is 50%, and the probability of being set to the second lower mode after playing a big role is 50%. In other words, in the first lower mode, after playing a big role, there is a 50% probability of transitioning to a mode (second lower mode) with a higher degree of advantage than the current mode (first lower mode), and after playing a big role, there is a 50% probability of resetting to a mode (first lower mode) with the same degree of advantage as the current mode (first lower mode).

[0172] In addition, in the second lower mode, the probability of being set to the first lower mode after playing a big role is 50%, and the probability of being set to the higher mode after playing a big role is 50%. That is, in the second lower mode, there is a 50% probability of transitioning to a mode (first lower mode) with a lower degree of advantage than the current mode (second lower mode) after playing a big role, and there is a 50% probability of transitioning to a mode (higher mode) with a higher degree of advantage than the current mode (second lower mode) after playing a big role. In other words, in the second lower mode, a new playability is provided in which a mode (second lower mode) with the same degree of advantage as the current mode (second lower mode) is not reset after playing a big role, which makes it possible to improve the interest of the game.

[0173] In addition, in the higher mode, the mode is reset to the higher mode with a 100% probability after the big role is played. In other words, in the higher mode, as long as the small win due to the special 2 variation is won, the game state after the big role is played is guaranteed to be set to the higher mode as a time-saving game state. In other words, in the higher mode, the mode in which the player is staying after the big role is played (the higher mode) will not be shifted to a mode in which the degree of advantage is reduced, so that the interest in the game can be improved.

[0174] In addition, after the first lower mode is set, if a specific winning result (special pattern Z4) is derived twice, the game will transition to a higher mode, which will provide new gameplay features and make the game more interesting.

[0175] In addition, after the first lower mode is set, a specific winning result (special pattern Z4) is derived, and then, if a predetermined winning result (special pattern Z3) is derived, a transition to the first lower mode is made, providing new gameplay characteristics and making the game more interesting.

[0176] In addition, after the second lower mode is set, a predetermined winning result (special pattern Z3) is derived, and then, if a specific winning result (special pattern Z4) is derived, a transition to the second lower mode is made, thereby providing new gameplay characteristics and making the game more interesting.

[0177] As described above, the game state after the big win is set based on the game state at the time of the small win and the type of the small win symbol that was won, thereby realizing the above-mentioned game characteristics. In order to realize the above-mentioned game characteristics, in this embodiment, the main control board 300 executes the following process. Below, the main process of the main control board 300 accompanying the progress of the game in the gaming machine 100 will be described.

[0178] Fig. 19 is a diagram for explaining the gaming machine status flag. In the main control board 300, whether or not a game can be played is managed by the gaming machine status flag. One of six flag values ​​from 00H to 05H is set to the gaming machine status flag. The flag value = 00H of the gaming machine status flag indicates a playable state, and when the gaming machine status flag is 00H, the game is controlled to proceed, and when the gaming machine status flag is other than 00H, the game is stopped.

[0179] The flag value of the gaming machine status flag = 01H indicates a setting change state, and when the gaming machine status flag is 01H, the registered setting value can be changed. The flag value of the gaming machine status flag = 02H indicates a setting confirmation state, and when the gaming machine status flag is 02H, the registered setting value can be confirmed by displaying it on the performance display monitor 184, for example. The flag value of the gaming machine status flag = 03H indicates a setting abnormal state, and when the gaming machine status flag is 03H, the registered setting value is considered abnormal and the game is stopped. The flag value of the gaming machine status flag = 04H indicates a RAM abnormal state, and when the gaming machine status flag is 04H, the game is stopped. The flag value of the gaming machine status flag = 05H indicates a checksum abnormal state, and when the gaming machine status flag is 05H, the game is stopped. When the power is turned on, the gaming machine status flag is set to one of the flag values, and a process according to the gaming machine status flag is performed.

[0180] (CPU initialization process of main control board 300) FIG. 20 is a first flowchart illustrating the CPU initialization process in main control board 300, and FIG. 21 is a second flowchart illustrating the CPU initialization process in main control board 300.

[0181] When power is supplied from the power supply board, a system reset occurs in the main CPU 300a, and the main CPU 300a performs the following CPU initialization process (S100).

[0182] (Step S100-1) When the power is turned on, the main CPU 300a reads a boot program from the main ROM 300b as an initial setting process, and also performs setting processes necessary for executing various processes.

[0183] (Step S100-3) The main CPU 300a sets a wait processing time in a timer counter.

[0184] (Step S100-5) The main CPU 300a judges whether a power-off warning signal has been detected. The main control board 300 is provided with a power-off detection circuit, and when the power supply voltage falls below a predetermined value, the power-off detection circuit outputs a power-off warning signal. If a power-off warning signal has been detected, the process proceeds to step S100-3, and if a power-off warning signal has not been detected, the process proceeds to step S100-7.

[0185] (Step S100-7) The main CPU 300a determines whether the wait time set in step S100-3 has elapsed. If it is determined that the wait time has elapsed, the process proceeds to step S100-9. If it is determined that the wait time has not elapsed, the process proceeds to step S100-5.

[0187] (Step S100-11) The main CPU 300a loads the flag value of the gaming machine status flag before the power is turned off into the D register.

[0188] (Step S100-13) The main CPU 300a calculates the checksum and determines whether the calculated checksum matches the checksum saved when the power was turned off (is normal) and whether the backup flag is normal. If it is determined that the backup flag and the checksum are normal, the process proceeds to step S100-15, and if it is determined that either one or both are not normal, the process proceeds to step S100-25.

[0189] (Step S100-15) The main CPU 300a sets an address that does not include a setting value or a gaming machine status flag as the first address to be cleared in the main RAM 300c.

[0190] (Step S100-17) Main CPU 300a determines whether a RAM clear operation signal has been input from RAM clear switch 182s (whether the RAM clear button has been pressed down). If it is determined that a RAM clear operation signal has been input, main CPU 300a proceeds to step S100-31, and if it is determined that a RAM clear operation signal has not been input, main CPU 300a proceeds to step S100-19.

[0191] (Step S100-19) The main CPU 300a judges whether the flag value of the gaming machine status flag loaded in the above step S100-11 is 00H (playable state), the setting change switch 180s is on, and the middle frame 104 is open. If it is judged that all three conditions are met, the process proceeds to step S100-21, and if it is judged that any one of the three conditions is not met, the process proceeds to step S100-23.

[0192] (Step S100-21) The main CPU 300a sets the gaming machine status flag to 02H (setting confirmation status). That is, when the power is normally turned on while the middle frame 104 is open, the setting change switch 180s is on, and the RAM clear button is not pressed, the gaming machine enters the setting confirmation status.

[0193] (Step S100-23) The main CPU 300a executes an initialization process to clear the areas of the main RAM 300c subsequent to the top address set in step S100-15 above that are to be cleared when the power is restored, and then proceeds to step S100-49.

[0194] (Step S100-25) The main CPU 300a sets 05H (checksum abnormal state) in the D register.

[0195] (Step S100-27) The main CPU 300a performs an outside area read / write check process for checking and clearing the read / write memory in the unused area.

[0196] (Step S100-29) The main CPU 300a sets an address including a setting value and a gaming machine status flag as the first address to be cleared in the main RAM 300c.

[0198] (Step S100-33) The main CPU 300a judges whether the check result of the read / write memory in the above step S100-31 is normal or not. If it is judged as normal, the process proceeds to step S100-37, and if it is judged as not normal, the process proceeds to step S100-35.

[0199] (Step S100-35) The main CPU 300a sets 04H (RAM abnormal state) in the D register, and moves the process to step S100-45.

[0200] (Step S100-37) The main CPU 300a judges whether 02H (setting confirmation state) is set in the D register. If it is judged that 02H is set, the process proceeds to step S100-39, and if it is judged that 02H is not set, the process proceeds to step S100-41.

[0201] (Step S100-39) The main CPU 300a sets the D register to 00H (playable state).

[0202] (Step S100-41) The main CPU 300a judges whether the setting change conditions are satisfied. If it is judged that the setting change conditions are satisfied, the process proceeds to step S100-43. If it is judged that the setting change conditions are not satisfied, the process proceeds to step S100-45. Note that the setting change conditions here include at least that the setting change switch 180s is turned on, that the middle frame 104 is open, and that a RAM clear operation signal is input from the RAM clear switch 182s.

[0203] (Step S100-43) The main CPU 300a sets the D register to 01H (setting changed state).

[0204] (Step S100-45) The main CPU 300a saves the value set in the D register in the gaming machine status flag.

[0205] (Step S100-47) The main CPU 300a executes an initialization process for clearing the items in the main RAM 300c that are to be cleared when the RAM is cleared, and moves the process to step S100-49.

[0206] (Step S100-49) The main CPU 300a performs a transmission process (storing the RAM clear designation command in a transmission buffer) of a dispensing command (RAM clear designation command) to inform the dispensing control board 310 that the main RAM 300c has been cleared.

[0207] (Step S100-51) The main CPU 300a loads the gaming machine status flag.

[0208] (Step S100-53) The main CPU 300a judges whether the gaming machine state flag loaded in the above step S100-51 is 00H (playable state). If it is judged to be 00H, the process proceeds to step S110, and if it is judged not to be 00H, the process proceeds to step S100-55.

[0209] (Step S110) The main CPU 300a performs a sub-command group set process, which will be described later.

[0212] (Step S100-59) The main CPU 300a performs processing to disable interrupts.

[0213] (Step S100-61) The main CPU 300a updates the initial value update random number for the winning symbol random number. The initial value update random number for the winning symbol random number is for determining the initial value and the end value of the winning symbol random number. In other words, when the winning symbol random number goes through one cycle from the initial value update random number for the winning symbol random number to the initial value update random number for the winning symbol random number -1 by the updating process of the winning symbol random number described later, the winning symbol random number is updated to the initial value update random number for the winning symbol random number at that time.

[0227] (Step S110-17) The main CPU 300a performs a special game phase designation command setting process for setting a special game phase designation command indicating a special game management phase in a transmission buffer. The special game management phase will be described later.

[0228] (Step S110-19) The main CPU 300a judges whether the special game management phase is in a special symbol variation waiting state. If it is judged that the special symbol variation waiting state, the process proceeds to step S110-21, and if it is judged that the special symbol variation waiting state is not, the sub-command group set process is terminated.

[0229] (Step S110-21) The main CPU 300a sets the customer waiting designation command in the transmission buffer, and ends the sub-command group setting process.

[0230] Next, a description will be given of interrupt processing in the main control board 300. Here, a description will be given of a power-off save processing (XINT interrupt processing) and a timer interrupt processing.

[0231] (Power off save process of main control board 300 (XINT interrupt process)) 23 is a flowchart explaining the power-off save process (XINT interrupt process) in the main control board 300. The main CPU 300a monitors the power-off detection circuit, and when the power supply voltage falls below a predetermined value, it interrupts the CPU initialization process to execute the power-off save process.

[0232] (Step S300-1) When the power-off warning signal is input, the main CPU 300a saves the registers.

[0233] (Step S300-3) The main CPU 300a checks the power-off warning signal.

[0234] (Step S300-5) Main CPU 300a determines whether a power-off warning signal has been detected. If it is determined that a power-off warning signal has been detected, the process proceeds to step S300-11. If it is determined that a power-off warning signal has not been detected, the process proceeds to step S300-7.

[0235] (Step S300-7) The main CPU 300a restores the registers.

[0236] (Step S300-9) The main CPU 300a performs a process for permitting an interrupt, and ends the power-off save process.

[0240] (Step S300-17) In order to set a power interruption occurrence monitoring time, the main CPU 300a sets a predetermined number of times the power interruption detection signal has been detected as the counter value of a loop counter.

[0241] (Step S300-19) The main CPU 300a checks the power-off warning signal.

[0242] (Step S300-21) The main CPU 300a judges whether a power-off warning signal has been detected. If it is judged that a power-off warning signal has been detected, the process proceeds to step S300-17. If it is judged that a power-off warning signal has not been detected, the process proceeds to step S300-23.

[0243] (Step S300-23) The main CPU 300a decrements the value of the loop counter set in step S300-17 above by one.

[0244] (Step S300-25) The main CPU 300a judges whether the counter value of the loop counter is 0. As a result, if it is judged that the counter value is not 0, the process proceeds to step S300-19, and if it is judged that the counter value is 0, the process proceeds to the above-mentioned CPU initialization process (step S100).

[0245] In addition, if a power outage actually occurs, the operation of the gaming machine 100 stops while steps S300-17 to S300-25 are being looped.

[0246] (Timer interrupt processing of main control board 300) 24 is a flowchart explaining the timer interrupt process in the main control board 300. The main control board 300 is provided with a reset clock pulse generating circuit that generates a clock pulse every predetermined period (4 milliseconds in this embodiment, hereinafter referred to as "4 ms"). When a clock pulse is generated by the reset clock pulse generating circuit, it interrupts the CPU initialization process (step S100) and executes the following timer interrupt process.

[0247] (Step S400-1) The main CPU 300a saves the registers.

[0248] (Step S400-3) The main CPU 300a performs processing for permitting an interrupt.

[0249] (Step S400-5) The main CPU 300a outputs the common data set in the common output buffer to the output port, and executes dynamic port output processing which controls the lighting of the first special pattern display 160, the second special pattern display 162, the first special pattern reserved indicator 164, the second special pattern reserved indicator 166, the normal pattern display 168, the normal pattern reserved indicator 170, the right hit notification indicator 172, and the performance display monitor 184.

[0252] (Step S400-11) The main CPU 300a determines whether the flag value loaded in step S400-9 is 00H (playable state). If it is determined that the flag value is 00H, the process proceeds to step S400-15. If it is determined that the flag value is not 00H, the process proceeds to step S400-13.

[0253] (Step S400-13) The main CPU 300a determines whether the flag value loaded in step S400-9 is equal to or greater than 03H (abnormal setting state). If it is determined that the flag value is equal to or greater than 03H, the process proceeds to step S400-27. If it is determined that the flag value is not equal to or greater than 03H, the process proceeds to step S450.

[0254] (Step S450) The main CPU 300a executes the setting-related processing, and moves the process to step S400-27, which will be described later.

[0255] (Step S400-15) The main CPU 300a performs a timer update process to update various timer counters. Here, unless otherwise specified, the timer counters are decremented every time the timer interrupt process of the main control board 300 is performed, and the decrement stops when the timer counters reach 0.

[0256] (Step S400-17) The main CPU 300a executes an update process for the initial value update random number for the winning symbol random number, similar to the above step S100-61.

[0257] (Step S400-19) The main CPU 300a performs a process to update the winning symbol random number. Specifically, the random number counter is updated by adding 1, and if the result of the addition exceeds the maximum value of the random number range, the random number counter is reset to 0, and if the random number counter has completed one cycle, the random number is updated from the value of the initial value update random number for the winning symbol random number at that time.

[0258] Although detailed explanations are omitted, in the embodiment, the small win determination random number and the win determination random number use hardware random numbers updated by a hardware random number generator built into the main control board 300. The hardware random number generator updates both the small win determination random number and the win determination random number according to certain rules, automatically changing the random number sequence every time the random number sequence goes through one cycle, and changing the start value every time the system is reset.

[0259] (Step S500) The main CPU 300a executes a switch management process to determine whether or not a signal has been input from the first start hole detection switch 120s, the second start hole detection switch 122s, the gate detection switch 124s, the big prize hole detection switch 128s, the specific area detection switch 140s, and the out ball detection switch 130s. Details of this switch management process will be described later.

[0260] (Step S600) The main CPU 300a executes a special game management process for controlling the progress of the special games. The details of the special game management process will be described later.

[0261] (Step S700) The main CPU 300a executes a normal game management process for controlling the progress of the normal game. The details of this normal game management process will be described later.

[0262] (Step S400-21) The main CPU 300a executes an error management process for determining various errors and making settings according to the error determination results.

[0263] (Step S400-23) The main CPU 300a checks the general prize hole detection switch 118s, the first start hole detection switch 120s, the second start hole detection switch 122s, and the large prize hole detection switch 128s, and executes prize hole switch processing to increment the corresponding counters for prize ball control, etc.

[0264] (Step S400-25) The main CPU 300a executes a payout control management process for creating and transmitting a payout command based on the counter value of the counter for controlling the winning balls set in the above step S400-23.

[0265] (Step S400-27) The main CPU 300a executes an external information management process for setting output data for external information to be output from the game information output terminal board 312 to the outside.

[0266] (Step S400-29) The main CPU 300a executes an LED display setting process that sets display data for controlling the lighting of various indicators (LEDs), such as the first special pattern display 160, the second special pattern display 162, the first special pattern reserve indicator 164, the second special pattern reserve indicator 166, the normal pattern display 168, the normal pattern reserve indicator 170, and the right hit notification indicator 172, in an output buffer corresponding to each common.

[0267] (Step S400-31) The main CPU 300a executes a solenoid output image synthesis process for synthesizing solenoid output images of the normal electric role solenoid 122c, the big winning port solenoid 128c, and the movable member drive solenoid 142c, and storing the synthesized images in an output port buffer.

[0268] (Step S400-33) The main CPU 300a executes a port output process for outputting the values ​​of the common output buffers stored in the respective output port buffers to the output ports.

[0269] (Step S400-35) The main CPU 300a performs processing to disable interrupts.

[0270] (Step S400-37) The main CPU 300a uses the unused area of ​​the main RAM 300c to perform processing for calculating a base ratio to be displayed on the performance display monitor 184, and executes a performance display monitor control processing for setting common data for displaying the calculated base ratio on the performance display monitor 184 in a common output buffer. In the performance display monitor control processing, the base ratio is calculated for each predetermined period. Here, the performance display monitor 184 may switch between the base ratio of the current period and the base ratio of the previous period at predetermined time intervals. Also, the base ratio displayed on the performance display monitor 184 may be switched in response to a predetermined operation.

[0271] (Step S400-39) The main CPU 300a restores the registers and ends the timer interrupt process.

[0272] FIG. 25 is a flowchart illustrating the above-mentioned setting-related process (S450).

[0273] (Step S450-1) The main CPU 300a judges whether the flag value of the gaming machine status flag is 01H (setting change status). If it is judged to be 01H, the process proceeds to step S450-3, and if it is judged not to be 01H, the process proceeds to step S450-15.

[0274] (Step S450-3) The main CPU 300a loads the registered setting values ​​stored in the setting value buffer into a predetermined processing area.

[0275] (Step S450-5) The main CPU 300a determines whether the RAM clear switch 182s has been pressed (whether a RAM clear operation signal has been input). If it is determined that the RAM clear switch 182s has been pressed, the process proceeds to step S450-7, and if it is determined that the RAM clear switch 182s has not been pressed, the process proceeds to step S450-9.

[0276] (Step S450-7) The main CPU 300a adds 1 to the setting value of the processing area.

[0277] (Step S450-9) The main CPU 300a judges whether the setting value of the processing area is within a predetermined value range (1 in this embodiment). If it is judged that the setting value is within the predetermined value range, the process proceeds to step S450-13, and if it is judged that the setting value is not within the predetermined value range, the process proceeds to step S450-11.

[0278] (Step S450-11) The main CPU 300a sets the setting value of the processing area to 1.

[0279] (Step S450-13) The main CPU 300a sets the setting value of the processing area in the setting value buffer.

[0280] (Step S450-15) The main CPU 300a judges whether the setting change switch 180s is on. If it is judged that the setting change switch 180s is on, the setting-related process is terminated, and if it is judged that the setting change switch 180s is not on, the process proceeds to step S450-17.

[0281] (Step S450-17) The main CPU 300a sets a setting-related end designation command indicating the end of the setting-related process in the transmission buffer.

[0282] (Step S110) The main CPU 300a executes the sub-command group set process of Fig. 22. That is, when the setting related process is executed, at the end of the process, the model command, the setting value designation command, the special chart 1 reservation designation command, the special chart 2 reservation designation command, the number of times command, the variation pattern selection state designation command, the special chart phase designation command, and the customer waiting designation command are transmitted to the sub-control board 330.

[0283] (Step S450-19) The main CPU 300a sets the gaming machine state flag to 00H (playable state), and ends the setting-related process.

[0284] As described above, according to the embodiment, when the power is normally turned on with the middle frame 104 open, the setting change switch 180s turned on, and the RAM clear button pressed, the gaming machine status flag is set to 01H (setting change status) in the CPU initialization process (FIG. 20). After that, the timer interrupt process is executed, but since the gaming machine status flag is set to 01H (setting change status), all processes related to the progress of the game (steps S400-15 to S400-25 in FIG. 24) are stopped, and setting-related processes are executed.

[0285] The setting-related process is repeatedly executed while the setting change switch 180s is on, and during this setting-related process, pressing the RAM clear button is accepted as a setting change operation for the registered setting value. That is, during the setting change process (S450-1 to S450-13) that accepts the setting change operation, the registered setting value stored in the setting value buffer is switched to one of multiple stages of setting values ​​in response to the setting change operation.

[0286] When the setting change switch 180s is switched off while the gaming machine status flag is set to 01H (setting change state), the setting change process ends and the gaming machine status flag is set to 00H (playable state). This allows the process related to the progress of the game to be executed from the next timer interrupt process.

[0287] Here, in the setting-related processing, after the operation of pressing the RAM clear button, i.e., the acceptance of the operation of changing the setting of the registered setting value, is finished, in the sub-command group set processing, a setting value designation command corresponding to the registered setting value is transmitted to the sub-control board 330. On the other hand, while the setting change operation is being accepted, the setting value designation command is not transmitted to the sub-control board 330. In this way, while the setting change operation is being accepted, the setting value designation command is not transmitted, and when the acceptance of the setting change operation is terminated and a transition is made to a state in which game progress is possible, the risk of the registered setting value being obtained illegally can be reduced by transmitting the setting value designation command.

[0288] In the embodiment, a plurality of flag values ​​including at least 01H (setting change state) are switched. When the gaming machine state flag is set to 01H (setting change state), setting-related processing is executable and the progress of the game is stopped. In this way, since setting-related processing is not executed while the game is in progress, a setting value designation command is not sent while the game is in progress, and the risk of the registered setting value being illegally obtained is reduced.

[0289] Next, among the above timer interrupt processing, the switch management processing in step S500, the special game management processing in step S600, and the normal game management processing in step S700 will be described in detail.

[0290] FIG. 26 is a flowchart illustrating the switch management process (step S500) in the main control board 300.

[0291] (Step S500-1) The main CPU 300a judges whether the gate detection switch is ON, that is, whether the game ball has passed through the gate 124 and the detection signal from the gate detection switch 124s has been turned ON. If it is judged that the gate detection switch is ON, the process proceeds to step S510, and if it is judged that the gate detection switch is not ON, the process proceeds to step S500-3.

[0292] (Step S510) The main CPU 300a executes a gate passing process based on the passage of the gaming ball through the gate 124. The gate passing process will be described in detail later.

[0293] (Step S500-3) The main CPU 300a judges whether the first start hole detection switch is ON, that is, whether a game ball has entered the first start hole 120 and a detection signal has been input from the first start hole detection switch 120s. If it is judged that the first start hole detection switch is ON, the process proceeds to step S520, and if it is judged that the first start hole detection switch is not ON, the process proceeds to step S500-5.

[0294] (Step S520) The main CPU 300a executes a first start hole passing process based on the entry of the gaming ball into the first start hole 120. The first start hole passing process will be described in detail later.

[0295] (Step S500-5) The main CPU 300a judges whether the second start hole detection switch is ON, that is, whether a game ball has entered the second start hole 122 and a detection signal has been input from the second start hole detection switch 122s. If it is determined that the second start hole detection switch is ON, the process proceeds to step S530, and if it is determined that the second start hole detection switch is not ON, the process proceeds to step S500-7.

[0296] (Step S530) The main CPU 300a executes a second start hole passing process based on the entry of the gaming ball into the second start hole 122. The second start hole passing process will be described in detail later.

[0297] (Step S500-7) The main CPU 300a judges whether the special prize opening detection switch is ON, that is, whether a game ball has entered the special prize opening 128 and a detection signal has been input from the special prize opening detection switch 128s. If it is judged that the special prize opening detection switch is ON, the process proceeds to step S500-9, and if it is judged that the special prize opening detection switch is not ON, the process proceeds to step S500-11.

[0298] (Step S500-9) The main CPU 300a judges whether or not a big prize game or a small prize game is currently being played, and judges whether the game ball entered the big prize opening 128 properly. If it is judged that a big prize game or a small prize game is not being played, a predetermined fraud detection process is executed, and if it is judged that a big prize game or a small prize game is being played and the game ball entered the big prize opening 128 properly, the main CPU 300a adds 1 to the big prize opening winning ball number counter and sets a big prize opening winning designation command in the transmission buffer.

[0299] (Step S500-11) The main CPU 300a judges whether the specific area detection switch is ON, that is, whether the game ball has entered the specific area 140b and a detection signal has been input from the specific area detection switch 140s. If it is judged that the specific area detection switch is ON, the process proceeds to step S540, and if it is judged that the specific area detection switch is not ON, the process proceeds to step S500-13.

[0300] (Step S540) The main CPU 300a executes a specific area passing process based on the entry of the gaming ball into the specific area 140b, and ends the switch management process. The specific area passing process will be described in detail later.

[0301] (Step S500-13) The main CPU 300a judges whether the general winning opening detection switch is on, that is, whether a game ball has entered the general winning opening 118 and a detection signal has been input from the general winning opening detection switch 118s. If it is judged that the general winning opening detection switch is on, the process proceeds to step S500-15, and if it is judged that the general winning opening detection switch is not on, the process proceeds to step S500-17.

[0302] (Step S500-15) The main CPU 300a sets a general prize slot winning designation command in the transmission buffer.

[0303] (Step S500-17) The main CPU 300a judges whether the out ball detection switch is on, i.e., whether a detection signal has been input from the out ball detection switch 130s. If it is determined that the out ball detection switch is on, the process proceeds to step S500-19, and if it is determined that the out ball detection switch is not on, the switch management process is terminated.

[0304] (Step S500-19) The main CPU 300a sets an out ball detection designation command in the transmission buffer and terminates the switch management process.

[0305] FIG. 27 is a flow chart illustrating the gate passage process in main control board 300 (step S510).

[0306] (Step S510-1) The main CPU 300a loads the winning determination random number updated by the hardware random number generating unit.

[0307] (Step S510-3) The main CPU 300a judges whether the counter value of the normal pattern reserved ball counter is equal to or greater than the maximum value, that is, whether the counter value of the normal pattern reserved ball counter is equal to or greater than 4. As a result, if it is judged that the counter value of the normal pattern reserved ball counter is equal to or greater than the maximum value, the gate passing process is terminated, and if it is judged that the normal pattern reserved ball counter is not equal to or greater than the maximum value, the process proceeds to step S510-5.

[0308] (Step S510-5) The main CPU 300a updates the counter value of the normal symbol reserved ball number counter to a value obtained by adding "1" to the current counter value.

[0309] (Step S510-7) The main CPU 300a determines which of the four storage units in the general reserve storage area is to be the target storage unit in which to save the acquired winning determination random number.

[0310] (Step S510-9) The main CPU 300a saves the winning determination random number obtained in the above step S510-1 in the target memory calculated in the above step S510-7.

[0311] (Step S510-11) The main CPU 300a sets a general map reservation designation command indicating the number of general map reservations stored in the general map reservation memory area in the transmission buffer, and terminates the gate passing process.

[0312] FIG. 28 is a flowchart illustrating the first start port passing process in the main control board 300 (step S520).

[0313] (Step S520-1) The main CPU 300a sets "00H" as the special symbol identification value. The special symbol identification value is for identifying whether the reserved type is special 1 reserved or special 2 reserved, and the special symbol identification value (00H) indicates special 1 reserved, and the special symbol identification value (01H) indicates special 2 reserved.

[0314] (Step S520-3) The main CPU 300a sets the address of the special pattern 1 reserved ball count counter.

[0315] (Step S535) The main CPU300a executes the special symbol random number acquisition process and ends the first start port passing process. This special symbol random number acquisition process is executed using a module common to the second start port passing process (step S530). Therefore, the details of the special symbol random number acquisition process will be explained after the explanation of the second start port passing process.

[0316] FIG. 29 is a flowchart illustrating the second start port passing process in the main control board 300 (step S530).

[0317] (Step S530-1) The main CPU 300a sets "01H" as the special symbol identification value.

[0318] (Step S530-3) The main CPU 300a sets the address of the special pattern 2 reserved ball count counter.

[0319] (Step S535) The main CPU 300a executes a special symbol random number acquisition process, which will be described later.

[0320] (Step S530-5) The main CPU 300a loads the normal game management phase. The normal game management phase indicates the stage of the execution process of the normal game, that is, the progress of the normal game, and is updated according to the stage of the execution process of the normal game, which will be described in detail later.

[0321] (Step S530-7) The main CPU 300a judges whether the normal game management phase loaded in the above step S530-5 is "04H". The normal game management phase "04H" indicates that the normal electric role winning hole opening control process is in progress. In this normal electric role winning hole opening control process, the normal electric role solenoid 122c is energized and the movable piece 122b is controlled to be in an open state, so here, it is judged whether the second start hole 122 is in a state in which it can be opened properly. As a result, if it is judged that the normal game management phase is not "04H", the second start hole passing process is terminated, and if it is judged that the normal game management phase is "04H", the process is transferred to step S530-9.

[0322] (Step S530-9) The main CPU 300a updates the counter value of the normal electric role winning ball counter to a value obtained by adding "1" to the current counter value, and ends the second start port passing process.

[0323] 30 is a flowchart explaining the special symbol random number acquisition process (step S535) in the main control board 300. This special symbol random number acquisition process is executed using a common module in the above-mentioned first start port passing process (step S520) and second start port passing process (step S530).

[0324] (Step S535-1) The main CPU 300a loads the special symbol identification value set in step S520-1 or step S530-1.

[0325] (Step S535-3) The main CPU 300a loads the number of reserved balls for the target special symbol. Here, if the special symbol identification value loaded in the above step S535-1 is "00H", the counter value of the special symbol 1 reserved ball counter, i.e., the special 1 reserved number, is loaded. Also, if the special symbol identification value loaded in the above step S535-1 is "01H", the counter value of the special symbol 2 reserved ball counter, i.e., the special 2 reserved number, is loaded.

[0326] (Step S535-5) The main CPU 300a loads the small win determination random number updated by the hardware random number generating unit.

[0327] (Step S535-7) The main CPU 300a judges whether the number of reserved balls of the target special symbol loaded in step S535-3 is equal to or greater than the upper limit. If it is judged to be equal to or greater than the upper limit, the process proceeds to step S535-23. If it is judged not to be equal to or greater than the upper limit, the process proceeds to step S535-9.

[0328] (Step S535-9) The main CPU 300a updates the counter value of the target special symbol reserved ball count counter to a value obtained by adding "1" to the current counter value.

[0329] (Step S535-11) The main CPU 300a determines which of the eight storage units in the special chart reservation storage area is to be the target storage unit in which the acquired small win determination random number is to be saved.

[0330] (Step S535-13) The main CPU 300a obtains the small win determination random number loaded in step S535-5, the winning pattern random number updated in step S400-19, the reach group determination random number, reach mode determination random number, and variation pattern random number updated in step S100-69, and stores them in the target memory unit calculated in step S535-11.

[0331] (Step S535-15) The main CPU 300a performs a special symbol reserved ball winning order setting process for updating and storing the winning order of the special 1 reserved and special 2 reserved balls stored in the special symbol reserved storage area.

[0332] (Step S535-17) The main CPU 300a executes the acquisition time performance determination process for performing the provisional lottery for the big role, the provisional decision of the winning symbol, and the provisional decision of the variable information based on the various random numbers stored in the target storage unit in the above step S535-13. In this acquisition time performance determination process, a pre-reading designation command indicating the variable information to be determined when the newly stored reserved is read out is transmitted to the sub-control board 330.

[0333] (Step S535-19) The main CPU 300a loads the counter values ​​of the special pattern 1 reserved ball number counter and the special pattern 2 reserved ball number counter.

[0334] (Step S535-21) The main CPU 300a sets the special reserved command in the transmission buffer based on the counter value loaded in step S535-19. Here, the special reserved command is set based on the counter value (special reserved number) of the special reserved ball number counter of the special pattern 1, and the special reserved command is set based on the counter value (special reserved number) of the special reserved ball number counter of the special pattern 2. As a result, the special reserved number and the special reserved number are transmitted to the sub-control board 330 every time the special reserved number or the special reserved number is stored.

[0335] (Step S535-23) The main CPU 300a loads the normal game management phase.

[0336] (Step S535-25) The main CPU 300a checks the normal game management phase loaded in step S535-23 and judges whether it is below the normal electric device winning opening control state described later. If it is judged to be below the normal electric device winning opening control state, the process proceeds to step S535-27, and if it is judged not to be below the normal electric device winning opening control state, the special symbol random number acquisition process is terminated.

[0337] (Step S535-27) The main CPU 300a determines whether or not an abnormal winning has occurred, and if it determines that an abnormal winning has occurred, executes a start port abnormal winning error process to perform a predetermined process, and ends the special pattern random number acquisition process (step S535).

[0338] FIG. 31 is a flowchart illustrating the specific area passing process in step S540.

[0339] (Step S540-1) When main CPU 300a determines in step S500-11 that the specific area detection switch ON has been detected, it determines whether or not the valid period flag is ON. If it determines that the valid period flag is ON, it moves the process to step S540-3, and if it determines that the valid period flag is not ON, it moves the process to step S540-9.

[0340] As will be described in more detail later, this valid period flag is used to determine whether the entry of a game ball into the specific area 140b is considered valid, and in this embodiment, it is turned on at the start of a small win game (first round game).

[0341] (Step S540-3) In the above step S540-1, if it is determined that the valid period flag is on, the main CPU 300a determines whether the specific area entry flag is on. The specific area entry flag is for identifying that the game ball has already validly entered the specific area 140b. If it is determined that the specific area entry flag is on, the specific area passing process is terminated, and if it is determined that the specific area entry flag is not on, the process proceeds to step S540-5.

[0342] (Step S540-5) The main CPU 300a turns on a specific area entry flag.

[0343] (Step S540-7) The main CPU 300a sets a specific area entry command in a transmission buffer to notify the sub-control board 330 that the gaming ball has validly entered the specific area 140b, and ends the specific area passing process.

[0344] (Step S540-9) The main CPU 300a executes a predetermined error process.

[0345] (Step S540-11) The main CPU 300a sets an error command indicating that an error has been detected in the transmission buffer, and ends the specific area passing process.

[0346] 32 is a diagram for explaining the special game management phase. As already described, in the embodiment, a special game triggered by the entry of a game ball into the first start hole 120 or the second start hole 122 and a normal game triggered by the passage of a game ball through the gate 124 proceed simultaneously in parallel. The processing related to the special game is executed stepwise and repeatedly, and the main control board 300 manages each processing related to such a special game by the special game management phase.

[0347] As shown in FIG. 32, the main ROM 300b stores a plurality of special game control modules for controlling the execution of special games, and each of these special game control modules is associated with a special game management phase. Specifically, when the special game management phase is "00H", a module for executing "special symbol change waiting process" is called, when the special game management phase is "01H", a module for executing "special symbol change in progress process" is called, when the special game management phase is "02H", a module for executing "special symbol stop pattern display process" is called, when the special game management phase is "03H" or "07H", a module for executing "large prize opening pre-processing" is called, when the special game management phase is "04H" or "08H", a module for executing "large prize opening opening control process" is called, when the special game management phase is "05H" or "09H", a module for executing "large prize opening closing valid process" is called, when the special game management phase is "06H" or "0AH", a module for executing "large prize opening end wait process" is called.

[0348] FIG. 33 is a flowchart illustrating the special game management process (step S600) in the main control board 300.

[0349] (Step S600-1) The main CPU 300a loads the special game management phase.

[0350] (Step S600-3) The main CPU 300a selects the special game control module corresponding to the special game management phase loaded in the above step S600-1.

[0351] (Step S600-5) The main CPU 300a calls the special game control module selected in step S600-3 and starts processing.

[0352] (Step S600-7) The main CPU 300a loads a special game timer that manages the control time of the special game, and ends the special game management process.

[0353] 34 is a flow chart for explaining the special symbol change waiting process in the main control board 300. This special symbol change waiting process is executed when the special game management phase is "00H".

[0354] (Step S610-1) The main CPU300a judges whether the counter value of the special symbol 2 reserved ball counter, that is, the special 2 reserved number (X2) is "1" or more. As a result, if it is judged that the special 2 reserved number (X2) is "1" or more, the process is transferred to step S610-7, and if it is judged that the special 2 reserved number (X2) is not "1" or more, the process is transferred to step S610-3.

[0355] (Step S610-3) The main CPU300a judges whether the counter value of the special symbol 1 reserved ball counter, that is, the special 1 reserved number (X1) is "1" or more. As a result, if it is judged that the special 1 reserved number (X1) is "1" or more, the process moves to step S610-7, and if it is judged that the special 1 reserved number (X1) is not "1" or more, the process moves to step S610-5.

[0356] (Step S610-5) The main CPU 300a sets a customer waiting designation command in a transmission buffer, executes a customer waiting setting process for setting a customer waiting state, and ends the special symbol change waiting process.

[0357] (Step S610-7) The main CPU300a transfers the special 2 reserved balls stored in the first to fourth storage units of the second special symbol reserved storage area, or the special 1 reserved balls stored in the first to fourth storage units of the first special symbol reserved storage area, to a storage unit with a smaller ordinal number by one. Specifically, when it is determined in the above step S610-1 that the number of reserved balls of the special symbol 2 is "1" or more, the special 2 reserved balls stored in the second to fourth storage units of the second special symbol reserved storage area are transferred to the first to third storage units. In addition, the main RAM300c is provided with a 0th storage unit to be processed, and the special 2 reserved balls stored in the 1st storage unit are block-transferred to the 0th storage unit. In addition, in the above step S610-3, if it is determined that the number of reserved balls of the special pattern 1 is "1" or more, the special pattern 1 reserved balls stored in the second to fourth storage units of the first special pattern reserved storage area are transferred to the first to third storage units, and the special pattern 1 reserved balls stored in the first storage unit are block-transferred to the 0th storage unit. In addition, in this special pattern storage area shift process, the counter value of the target special pattern reserved ball count counter corresponding to the reserved type transferred to the 0th storage unit is decremented by "1," and a reserved reduction designation command indicating that the special pattern 1 reserved balls or special pattern 2 reserved balls have been decremented by "1" is set in the transmission buffer.

[0358] (Step S610-9) The main CPU 300a loads the small win determination random number and the reserved type transferred to the 0th memory unit, selects the corresponding small win determination random number judgment table, performs a lottery for a big role, and executes a special symbol win judgment process that stores the lottery result.

[0359] (Step S610-11) The main CPU300a executes a special symbol pattern determination process for determining a special symbol. Here, if the result of the big role lottery in the above step S610-9 is a small win, the winning symbol random number and reservation type transferred to the 0th storage unit are loaded, the corresponding winning symbol random number determination table is selected to extract special symbol determination data, and the extracted special symbol determination data (type of small win symbol) is saved. Also, if the result of the big role lottery in the above step S610-9 is a loss, the special symbol determination data for loss (type of loss symbol) corresponding to the reservation type is saved. Specifically, if the reservation type is special 1 reservation, the special symbol X is saved as a loss symbol, and if the reservation type is special 2 reservation, the special symbol Y is saved as a loss symbol. In this way, after the special symbol determination data is saved, a symbol type designation command corresponding to the special symbol determination data is set in the transmission buffer.

[0360] (Step S610-13) The main CPU 300a saves the special symbol stop symbol number corresponding to the special symbol determination data extracted in the above step S610-11. The first special symbol display 160 and the second special symbol display 162 are each composed of 7 segments, and each segment constituting the 7 segments is associated with a number (counter value). The special symbol stop symbol number determined here indicates the number (counter value) of the segment that will finally be lit.

[0361] (Step S612) The main CPU 300a executes a special symbol variable number determination process for determining a variable mode number and a variable pattern number. The details of this special symbol variable number determination process will be described later.

[0362] (Step S610-15) The main CPU300a loads the fluctuation mode number and the fluctuation pattern number determined in the above step S612, and determines the fluctuation time 1 and the fluctuation time 2 by referring to the fluctuation time determination table. Then, the total time of the determined fluctuation times 1 and 2 is set in the special symbol fluctuation timer.

[0363] (Step S610-17) The main CPU 300a performs a reserve area setting process for storing the type of small winning symbol (special symbol determination data) and the like in the reserve area of ​​the main RAM 300c.

[0364] (Step S610-19) The main CPU 300a executes a process of setting a special symbol display counter in order to start the variable display of the special symbol in the first special symbol display 160 or the second special symbol display 162. A counter value is associated with each segment of the 7-segment that constitutes the first special symbol display 160 and the second special symbol display 162, and the segment corresponding to the counter value set in the special symbol display counter is controlled to light up. Here, the counter value corresponding to the segment to be lit at the start of the variable display of the special symbol is set in the special symbol display counter. In addition, the special symbol display counter is provided separately as a special symbol 1 display counter corresponding to the first special symbol display 160 and a special symbol 2 display counter corresponding to the second special symbol display 162, and here, a counter value is set in the counter corresponding to the reservation type.

[0365] (Step S610-21) The main CPU 300a loads the counter values ​​of the special pattern 1 reserved ball counter and the special pattern 2 reserved ball counter, and sets the special pattern reserved designation command in the transmission buffer. Here, the special pattern 1 reserved designation command is set based on the counter value (special 1 reserved number) of the special pattern 1 reserved ball counter, and the special pattern 2 reserved designation command is set based on the counter value (special 2 reserved number) of the special pattern 2 reserved ball counter. Also, here, the special pattern winning order command corresponding to the winning order of the special 1 reserved and special 2 reserved stored in the above step S610-7 is set in the transmission buffer. As a result, every time the special 1 reserved or special 2 reserved is consumed, the special 1 reserved number and the special 2 reserved number, as well as the winning order of each of these reserved balls, are transmitted to the sub-control board 330.

[0366] (Step S610-23) The main CPU 300a updates the special game management phase to "01H" and ends the special symbol change waiting process.

[0367] FIG. 35 is a flowchart illustrating the special symbol variable number determination process in the main control board 300.

[0368] (Step S612-1) The main CPU 300a judges whether the result of the big role lottery in the above step S610-9 is a small win. If it is judged to be a small win, the process proceeds to step S612-3, and if it is judged not to be a small win (miss), the process proceeds to step S612-5.

[0369] (Step S612-3) The main CPU 300a sets a reach mode determination random number judgment table corresponding to the current game state, the type of small winning symbol, the reserved type, and the variable state.

[0370] (Step S612-5) When the hold type of the read hold is special 2 hold, the main CPU 300a checks the counter value of the special pattern 2 hold ball count counter, and when the hold type of the read hold is special 1 hold, the main CPU 300a checks the counter value of the special pattern 1 hold ball count counter.

[0371] (Step S612-7) The main CPU300a sets the corresponding reach group determination random number judgment table based on the current game state, the reserved number and reserved type confirmed in the above step S612-5. Then, based on the set reach group determination random number judgment table and the reach group determination random number transferred to the 0th storage unit in the above step S610-7, it determines the reach group (group type).

[0372] (Step S612-9) The main CPU 300a sets a loss-time reach mode determination random number judgment table corresponding to the group type determined in step S612-7.

[0373] (Step S612-11) The main CPU 300a determines a variation mode number based on the reach mode determination random number judgment table set in the above step S612-3 or step S612-9 and the reach mode determination random number transferred to the 0th storage unit in the above step S610-7. Here, a variation pattern random number judgment table is also determined together with the variation mode number.

[0374] (Step S612-13) The main CPU 300a sets in the transmission buffer the fluctuation mode command corresponding to the fluctuation mode number determined in step S612-11 above.

[0375] (Step S612-15) The main CPU 300a determines a variation pattern number based on the variation pattern random number determination table determined in step S612-11 above and the variation pattern random number transferred to the 0th storage unit in step S610-7 above.

[0376] (Step S612-17) The main CPU 300a sets the variation pattern command corresponding to the variation pattern number determined in the above step S612-15 in the transmission buffer, and ends the special pattern variation number determination process.

[0377] 36 is a flow chart for explaining the special symbol variation process in the main control board 300. This special symbol variation process is executed when the special game management phase is "01H".

[0378] (Step S620-1) The main CPU 300a executes a process to update the special symbol variation base counter. The special symbol variation base counter is set to a counter value that completes one revolution in a predetermined cycle (e.g., 100 ms). Specifically, if the counter value of the special symbol variation base counter is "0", a predetermined counter value (e.g., 25) is set, and if the counter value is "1" or more, the counter value is updated to a value obtained by subtracting "1" from the current counter value.

[0379] (Step S620-3) The main CPU 300a judges whether the counter value of the special symbol variation base counter updated in the above step S620-1 is "0". If the counter value is "0", the process proceeds to step S620-5. If the counter value is not "0", the process proceeds to step S620-9.

[0380] (Step S620-5) The main CPU 300a performs a special symbol fluctuation timer update process for subtracting a predetermined value from the timer value of the special symbol fluctuation timer set in the above step S610-15.

[0381] (Step S620-7) The main CPU 300a judges whether the timer value of the special symbol fluctuation timer updated in the above step S620-5 is "0". If the timer value is "0", the process proceeds to step S620-15, and if the timer value is not "0", the process proceeds to step S620-9.

[0382] (Step S620-9) The main CPU 300a updates the special symbol display timer that measures the lighting time of each of the 7-segment segments that make up the first special symbol display device 160 and the second special symbol display device 162. Specifically, if the timer value of the special symbol display timer is "0", a predetermined timer value is set, and if the timer value is "1" or more, the timer value is updated to a value obtained by subtracting "1" from the current timer value.

[0383] (Step S620-11) The main CPU 300a judges whether the timer value of the special symbol display timer is "0". If it is judged that the timer value of the special symbol display timer is "0", the process proceeds to step S620-13, and if it is judged that the timer value of the special symbol display timer is not "0", the process during the special symbol variation is terminated.

[0384] (Step S620-13) The main CPU 300a updates the counter value of the special symbol display symbol counter to be updated, and ends the special symbol variation process. As a result, each segment constituting the 7-segment display is sequentially lit at predetermined time intervals.

[0385] (Step S620-15) The main CPU 300a updates the special game management phase to "02H".

[0386] (Step S620-17) The main CPU 300a saves the special symbol stop symbol number (counter value) determined in step S610-13 in the target special symbol display symbol counter. As a result, the determined special symbol is stopped and displayed on the first special symbol display device 160 or the second special symbol display device 162.

[0387] (Step S620-19) The main CPU 300a sets a special symbol stop designation command, which indicates that a special symbol has been stopped and displayed on the first special symbol display device 160 or the second special symbol display device 162, in the transmission buffer.

[0388] (Step S620-21) The main CPU 300a sets a special symbol variation stop time, which is the time for stopping and displaying the special symbol, in a special game timer, and ends the special symbol variation process.

[0389] 37 is a flow chart for explaining the special symbol stop symbol display process in the main control board 300. This special symbol stop symbol display process is executed when the special game management phase is "02H".

[0390] (Step S630-1) The main CPU 300a judges whether the timer value of the special game timer set in the above step S620-21 is "0". If it is judged that the timer value of the special game timer is not "0", the process proceeds to step S631, and if it is judged that the timer value of the special game timer is "0", the process proceeds to step S630-3.

[0391] (Step S631) The main CPU 300a executes a number-of-times-off management process, and ends the special symbol stop symbol display process. This number-of-times-off management process will be described later.

[0392] (Step S630-3) The main CPU 300a turns off the number-of-times management flag indicating that the number-of-times management process of step S631 has been executed.

[0393] (Step S630-5) The main CPU 300a sets in the transmission buffer a game state confirmation command at the time of special symbol determination, which indicates the game state at the time when the special symbol is determined.

[0394] (Step S630-7) The main CPU 300a sets in the transmission buffer a number command for transmitting the number of times of time reduction, the number of times of small win time reduction end operation (Z3), and the number of times of small win time reduction end operation (Z4) updated in the number-cut management process of the above step S631 to the sub-control board 330.

[0395] (Step S630-9) The main CPU 300a checks the result of the big role lottery.

[0396] (Step S630-11) The main CPU 300a judges whether the result of the big role lottery is a small win. If it is judged to be a small win, the process proceeds to step S630-15. If it is judged not to be a small win, the process proceeds to step S630-13.

[0397] (Step S630-13) The main CPU300a updates the special game management phase to "00H" and ends the special symbol stop symbol display process. This ends the special game management process based on the reservation of 1, and if special reservation 1 or special reservation 2 is stored, processing to start the variable display of the special symbol based on the next reservation will be performed.

[0398] (Step S630-15) The main CPU 300a sets data in the special electric role operation RAM set table according to the type of the determined special symbol.

[0399] (Step S630-17) The main CPU 300a performs a process for setting the maximum number of times that the special electric device operates. Specifically, the data set in the above step S630-15 is referenced, and a predetermined number (counter value corresponding to the type of special symbol=number of rounds) is set as a counter value in the maximum number of times that the special electric device operates counter. The maximum number of times that the special electric device operates counter indicates the number of rounds ("1") that can be executed in the small win game that is about to start. Meanwhile, the main RAM 300c is provided with a counter for the number of consecutive times that the special electric device operates, and the current number of rounds is managed by adding "1" to the counter value of the counter for the number of consecutive times that the special electric device operates at the start of each round game. Here, a process for resetting (updating to "0") the counter value of the counter for the number of consecutive times that the special electric device operates is also executed with the start of the small win game.

[0400] (Step S630-19) The main CPU 300a refers to the data set in step S630-17, and saves a predetermined opening time as a timer value in the special game timer.

[0401] (Step S630-21) The main CPU 300a sets in the transmission buffer an opening designation command for transmitting the start of the small winning game to the sub-control board 330. Note that this opening designation command is provided for each opening time, and here, the opening designation command corresponding to the opening time saved in the above step S630-19 is set in the transmission buffer.

[0402] (Step S630-23) The main CPU 300a updates the special game management phase to "03H" and ends the special symbol stop symbol display process. This starts the small win game.

[0403] FIG. 38 is a flowchart illustrating the number of cutoff management process in the main control board 300.

[0404] (Step S631-1) The main CPU 300a judges whether the number of times cutoff management flag is off. If the number of times cutoff management flag is off, the process proceeds to step S631-3. If the number of times cutoff management flag is not off (on), the main CPU 300a ends the number of times cutoff management process.

[0405] (Step S631-3) The main CPU300a turns on the number-of-times cut management flag. That is, in the embodiment, each process from step S631-3 onwards is executed when the special symbol stop symbol display process is executed for the first time after the special symbol change stop time (fixed time) is set. Note that the number-of-times cut management process may be executed when the special symbol change stop time (fixed time) is set, that is, when the change time has elapsed (step S620-15 onwards in FIG. 36).

[0406] (Step S631-5) The main CPU300a loads a time-saving state flag for identifying whether the game state is a non-time-saving game state or a time-saving game state, and checks whether the current game state is a non-time-saving game state or a time-saving game state. If the current game state is a time-saving game state, the process proceeds to step S631-7, and if the current game state is a non-time-saving game state, the process proceeds to step S631-19.

[0407] (Step S631-7) The main CPU 300a checks the result of the big role lottery.

[0408] (Step S631-9) The main CPU 300a judges whether the result of the big role lottery is a small win or not. If it is a small win, the process proceeds to step S631-11. If it is not a small win, the process proceeds to step S631-19.

[0409] (Step S631-11) The main CPU300a judges whether the value of the target small win counter is 1 or more. As a result, if it is judged that the value of the target small win counter is 1 or more, the process moves to step S631-13, and if it is judged that the value of the target small win counter is not 1 or more, the process moves to step S631-19. Specifically, in the above step S620-17, if the special pattern Z3 is stopped and displayed on the second special pattern display 162, the main CPU300a judges whether the value of the small win counter (Z3) is 1 or more. Also, in the above step S620-17, if the special pattern Z4 is stopped and displayed on the second special pattern display 162, the main CPU300a judges whether the value of the small win counter (Z4) is 1 or more. In addition, in the above step S620-17, when the special symbol Z1 or the special symbol Z2 is stopped and displayed on the first special symbol display device 160, the main CPU 300a shifts the process to step S631-19.

[0410] (Step S631-13) The main CPU 300a subtracts "1" from the small win counter of the target determined to have a value of 1 or more in the above step S631-11. That is, when the special symbol Z3 is stopped and displayed on the second special symbol display 162, the small win counter (Z3) is subtracted by "1", and when the special symbol Z4 is stopped and displayed on the second special symbol display 162, the small win counter (Z4) is subtracted by "1".

[0411] (Step S631-15) The main CPU 300a judges whether the small win counter updated in step S631-13 has changed from 1 to 0. If it has changed from 1 to 0, the process proceeds to step S631-17. If it has not changed from 1 to 0, the process proceeds to step S631-19.

[0412] (Step S631-17) The main CPU300a sets the game state to a non-time-reduction game state. As described above, when the first lower mode is set, the small win count (Z3) counter and the small win count (Z4) counter are set to "1". Therefore, when the special symbol Z3, which is a small win symbol, is won during the first lower mode, the small win count (Z3) counter is updated from 1 to 0 in step S631-13, and the game state is changed to a non-time-reduction game state in step S631-17. Also, when the special symbol Z4, which is a small win symbol, is won during the first lower mode, the small win count (Z4) counter is updated from 1 to 0 in step S631-13, and the game state is changed to a non-time-reduction game state in step S631-17. Also, as described above, when the second lower mode is set, the small win count (Z3) counter is set to "1". Therefore, if the special symbol Z3, which is a small win symbol, is won during the second lower mode, the small win count (Z3) counter is updated from 1 to 0 in step S631-13, and the game state is changed to a non-time-saving game state in step S631-17.

[0413] On the other hand, as described above, when the second lower mode is set, the small win count (Z4) counter is set to "0". Therefore, when the special symbol Z4, which is a small win symbol, is won during the second lower mode, the result of step S631-11 is NO, and the process skips steps S631-13 to S631-17 and proceeds to step S631-19. Therefore, when the special symbol Z4, which is a small win symbol, is won during the second lower mode, the game state is not set to a non-time-saving game state in step S631-17. Also, as described above, when the higher mode is set, the small win count (Z3) counter and the small win count (Z4) counter are set to "0". Therefore, if the special symbol Z3 or Z4, which is a small winning symbol, is won during the second lower mode, the result of step S631-11 is NO, and the process skips steps S631-13 to S631-17 and proceeds to step S631-19. Therefore, if the special symbol Z3 or Z4, which is a small winning symbol, is won during the higher mode, the game state is not set to the non-time-saving game state in step S631-17.

[0414] (Step S631-19) The main CPU 300a judges whether the result of the big role lottery is a small win or not. If it is a small win, the process proceeds to step S631-21, and if it is not a small win, the process proceeds to step S631-25.

[0415] (Step S631-21) The main CPU 300a sets the reserve area. The reserve area is provided in the main RAM 300c, and is a storage area for storing in advance the game state to be set after the big win game. Here, the current game state is referred to as the game state at the time of winning the small win, and the game state to be set after the big win game (time-saving state flag), the time-saving count cut counter, the small win count (Z3) counter, and the small win count (Z4) counter are stored as shown in FIG. 15 based on the current game state and the type of the small win pattern that was won. As will be described in detail later, when the big win game is executed, the game state and the counter values ​​of each counter stored in the reserve area at the end of the big win game are set.

[0416] (Step S631-23) The main CPU 300a sets the gaming state to a non-time-reduction gaming state, and ends the number-cut management process.

[0417] As described above, when the first lower mode is set, the small win count (Z3) counter and the small win count (Z4) counter are set to "1". Therefore, when the special symbol Z3, which is a small win symbol, is won during the first lower mode, the small win count (Z3) counter is updated from 1 to 0 in step S631-13, and the game state is changed to a non-time-saving game state in step S631-17. As a result, when the special symbol Z3, which is a small win symbol, is won during the first lower mode, the non-time-saving game state is referred to as the game state at the time of winning the small win, regardless of the game state at the start of the change. As a result, as shown in FIG. 18, when the special symbol Z3 is won during the first lower mode, the first lower mode is set.

[0418] In addition, if the special symbol Z4, which is a small win symbol, is won during the first lower mode, the small win count (Z4) counter is updated from 1 to 0 in step S631-13, and the game state is changed to the non-time-saving game state in step S631-17. As a result, if the special symbol Z4, which is a small win symbol, is won during the first lower mode, the non-time-saving game state is referred to as the game state at the time of winning the small win, regardless of the game state at the start of the change. As a result, as shown in FIG. 18, if the special symbol Z4 is won during the first lower mode, the game is set to the second lower mode.

[0419] Also, as described above, when the second lower mode is set, the small win count (Z3) counter is set to "1". Therefore, when the special symbol Z3, which is a small win symbol, is won during the second lower mode, the small win count (Z3) counter is updated from 1 to 0 in step S631-13, and the game state is changed to a non-time-saving game state in step S631-17. As a result, when the special symbol Z3, which is a small win symbol, is won during the second lower mode, the non-time-saving game state is referred to as the game state at the time of winning the small win, regardless of the game state at the start of the change. As a result, as shown in FIG. 18, when the special symbol Z3 is won during the second lower mode, the first lower mode is set.

[0420] Also, as described above, when the second lower mode is set, the small win count (Z4) counter is set to "0." Therefore, when the special symbol Z4, which is a small win symbol, is won during the second lower mode, the result of step S631-11 is NO, and the process of steps S631-13 to S631-17 is skipped, and the preliminary area is set in step S631-21.

[0421] Therefore, when the special symbol Z4, which is a small winning symbol, is won during the second lower mode, the time-saving game state is referred to as the game state when the small winning symbol is won. Then, after the preliminary area is set, in step S631-23, the game state is set to a non-time-saving game state. In this way, when the special symbol Z4, which is a small winning symbol, is won during the second lower mode, the time-saving game state is referred to as the game state when the small winning symbol is won, regardless of the game state at the start of the variation. As a result, as shown in FIG. 18, when the special symbol Z4 is won during the second lower mode, the higher mode is set.

[0422] Also, as described above, when the higher mode is set, the small win count (Z3) counter and the small win count (Z4) counter are set to "0." Therefore, when the special pattern Z3 or special pattern Z4, which is a small win pattern, is won during the second lower mode, the result is NO in step S631-11, and the process from step S631-13 to step S631-17 is skipped, and the preliminary area is set in step S631-21.

[0423] Therefore, when the special symbol Z3 or Z4, which is a small winning symbol, is won during the higher mode, the time-saving game state is referred to as the game state at the time of winning the small winning. Then, after the preliminary area is set, in step S631-23, the game state is set to the non-time-saving game state. In this way, when the special symbol Z3 or Z4, which is a small winning symbol, is won during the higher mode, the time-saving game state is referred to as the game state at the time of winning the small winning, regardless of the game state at the start of the variation. As a result, as shown in FIG. 18, when the special symbol Z3 or Z4 is won during the higher mode, the higher mode is set.

[0424] (Step S631-25) The main CPU 300a subtracts "1" from the time-saving count counter. In addition, when the time-saving end condition is set to, for example, the special 1 time-saving count, which is subtracted only when the result of the big role lottery based on the special 1 reservation is confirmed, and the special 2 time-saving count, which is subtracted only when the result of the big role lottery based on the special 2 reservation is confirmed, the main CPU 300a subtracts "1" from the special 1 time-saving count counter when a special pattern is stopped and displayed on the first special pattern display 160, and subtracts "1" from the special 2 time-saving count counter when a special pattern is stopped and displayed on the second special pattern display 162.

[0425] (Step S631-27) The main CPU 300a judges whether the time-saving cut-off counter updated in the above step S631-25 has changed from 1 to 0. If it has changed from 1 to 0, the process proceeds to step S631-29, and if it has not changed from 1 to 0, the process ends.

[0426] (Step S631-29) The main CPU 300a sets the gaming state to a non-time-reduction gaming state, and ends the number-cut management process.

[0427] 39 is a flow chart for explaining the process before the opening of the special prize opening in the main control board 300. This process before the opening of the special prize opening is executed when the special game management phase is "03H" or "07H".

[0428] (Step S640-1) The main CPU300a judges whether the timer value of the special game timer is not "0". As a result, if it is judged that the timer value of the special game timer is not "0", the main CPU300a ends the processing before opening the large prize opening, and if it is judged that the timer value of the special game timer is "0", the processing proceeds to step S640-3.

[0429] (Step S640-3) The main CPU 300a updates the counter value of the special electric role continuous operation number counter to a value obtained by adding "1" to the current counter value.

[0430] (Step S640-5) The main CPU 300a sets in the transmission buffer a special prize opening designation command for transmitting the start of opening of the special prize opening 128 (start of a round of play) to the sub-control board 330.

[0431] (Step S641) The main CPU 300a executes a special prize opening / closing switching process, which will be described later.

[0432] (Step S640-7) The main CPU 300a judges whether the special game management phase is 03H, that is, whether a small win game is being played. If it is judged that the special game management phase is 03H, the process proceeds to step S640-9. If it is judged that the special game management phase is not 03H, the process proceeds to step S640-13.

[0433] (Step S640-9) The main CPU 300a judges whether it is the start of the first round of play based on the counter value of the special electric device continuous operation number counter. If it is judged as the start of the first round of play, the process proceeds to step S640-11, and if it is judged as not the start of the first round of play, the process proceeds to step S640-13.

[0434] (Step S640-11) The main CPU 300a turns on the valid period flag, which enables the entry of the gaming ball into the specific area 140b when the small win game starts.

[0435] (Step S640-13) The main CPU 300a updates the special game management phase to a value obtained by adding 01H to the current value ("04H" or "08H"), and ends the pre-opening process for the special game slot.

[0436] FIG. 40 is a flowchart illustrating the special prize opening / closing switching process in the main control board 300.

[0437] (Step S641-1) The main CPU 300a judges whether the counter value of the special electric accessory opening / closing switching counter is the upper limit value of the special electric accessory opening / closing switching count (the number of times the special winning opening 128 is opened / closed during one round of play). If it is judged that the counter value is the upper limit value, the main CPU 300a ends the special winning opening opening / closing switching process, and if it is judged that the counter value is not the upper limit value, the process proceeds to step S641-3.

[0438] (Step S641-3) The main CPU 300a refers to the data in the special electric device operation RAM set table, and extracts solenoid control data for controlling the energization of the large prize opening solenoid 128c, as well as timer data which is the energization time or non-energization time of the large prize opening solenoid 128c, based on the counter value of the special electric device opening / closing switching count counter.

[0439] (Step S641-5) The main CPU 300a executes a large prize opening solenoid energization control process to start energization of the large prize opening solenoid 128c or to stop energization of the large prize opening solenoid 128c based on the solenoid control data extracted in the above step S641-3. By executing this large prize opening solenoid energization control process, the start or stop of energization of the large prize opening solenoid 128c is controlled in the above steps S400-31 and S400-33.

[0440] (Step S641-7) The main CPU 300a saves the timer value based on the timer data extracted in the above step S641-3 in the special game timer. The timer value saved in the special game timer here is the maximum opening time of the big winning port 128 once.

[0441] (Step S641-9) The main CPU 300a judges whether the special prize opening solenoid 128c is in the energization start state, that is, whether the control process to start energization of the special prize opening solenoid 128c has been performed in the above step S641-5. If it is judged to be in the energization start state, the process proceeds to step S641-11, and if it is judged not to be in the energization start state, the special prize opening opening open / close switching process is terminated.

[0442] (Step S641-11) The main CPU 300a updates the counter value of the special electric role opening / closing switching count counter to a value obtained by adding "1" to the current counter value, and ends the large prize opening opening / closing switching process.

[0443] 41 is a flow chart for explaining the special prize opening control process in the main control board 300. This special prize opening control process is executed when the special game management phase is "04H" or "08H".

[0444] (Step S650-1) The main CPU 300a judges whether the timer value of the special game timer saved in the above step S641-7 is "0". If it is judged that the timer value of the special game timer is not "0", the process proceeds to step S650-5, and if it is judged that the timer value of the special game timer is "0", the process proceeds to step S650-3.

[0445] (Step S650-3) The main CPU 300a judges whether the counter value of the special electric role opening / closing switching counter is the upper limit value of the special electric role opening / closing switching count. If it is judged that the counter value is the upper limit value, the process proceeds to step S650-7, and if it is judged that the counter value is not the upper limit value, the process proceeds to step S641.

[0446] (Step S641) In the above step S650-3, when it is determined that the counter value of the special electric role opening / closing switching number counter is not the upper limit value of the special electric role opening / closing switching number, the main CPU 300a executes the process of the above step S641.

[0447] (Step S650-5) The main CPU 300a judges whether the counter value of the special prize opening winning ball counter updated in the above step S500-9 has reached a specified number, that is, whether the same number of game balls as the maximum number of winnings in one round have entered the special prize opening 128. As a result, if it is judged that the specified number has not been reached, the special prize opening opening opening control process is terminated, and if it is judged that the specified number has been reached, the process proceeds to step S650-7.

[0448] (Step S650-7) The main CPU 300a executes a special prize opening closing process required to stop the energization of the special prize opening solenoid 128c and close the special prize opening 128. As a result, the special prize opening 128 is brought into a closed state.

[0449] (Step S650-9) The main CPU 300a saves the effective time (interval time) for closing the special winning port in the special game timer.

[0450] (Step S650-11) The main CPU 300a updates the special game management phase to a value obtained by adding 01H to the current value ("05H" or "09H").

[0451] (Step S650-13) The main CPU 300a sets a special prize opening closure designation command, which indicates that the special prize opening 128 has been closed, in the transmission buffer, and ends the special prize opening opening control process.

[0452] 42 is a flow chart for explaining the special prize opening close validity process in the main control board 300. This special prize opening close validity process is executed when the special game management phase is "05H" or "09H".

[0453] (Step S660-1) The main CPU 300a judges whether the timer value of the special game timer saved in the above step S650-9 is "0". As a result, if it is judged that the timer value of the special game timer is not "0", the main CPU 300a ends the big prize opening closure valid processing, and if it is judged that the timer value of the special game timer is "0", the processing proceeds to step S660-3.

[0454] (Step S660-3) The main CPU 300a judges whether the counter value of the special electric device continuous operation counter matches the counter value of the special electric device maximum operation counter, that is, whether a preset number of rounds have been played. If it is judged that the counter value of the special electric device continuous operation counter matches the counter value of the special electric device maximum operation counter, the process proceeds to step S660-9, and if it is judged that they do not match, the process proceeds to step S660-5.

[0455] (Step S660-5) The main CPU300a updates the special game management phase to "07H". When the special game management phase is "05H", that is, during the control of the small win game, the number of rounds of the small win game is "1", so that the result of the determination in step S660-3 is YES and the process does not proceed to the step.

[0456] (Step S660-7) The main CPU 300a saves the predetermined special prize opening closing time in the special game timer and ends the special prize opening closing validity process, thereby starting the next round of games.

[0457] (Step S660-9) The main CPU 300a judges whether the special game management phase is 05H, that is, whether a small win game is being played. If it is judged that the special game management phase is 05H, the process proceeds to step S660-11. If it is judged that the special game management phase is not 05H, the process proceeds to step S660-21.

[0458] (Step S660-11) The main CPU 300a judges whether all the game balls that entered the large prize opening 128 have been discharged. Here, when the value obtained by subtracting the total number of game balls that entered the specific area 140b and the non-specific area 140c from the number of game balls that entered the large prize opening 128 becomes 0, it is judged that the discharge is completed. If it is judged that the discharge is completed, the process proceeds to step S660-13, and if it is judged that the discharge is not completed, the large prize opening closing valid process is terminated. Note that if the judgment result that the discharge is not completed is continuously derived for a certain period of time, an error process is performed.

[0459] (Step S660-13) The main CPU 300a determines whether the specific area entry flag is on. If it is determined that the specific area entry flag is on, the process proceeds to step S660-15. If it is determined that the specific area entry flag is not on, the process proceeds to step S660-21.

[0460] (Step S660-15) The main CPU 300a turns off the specific area entry flag.

[0461] (Step S660-17) The main CPU 300a checks the type of small winning symbol and sets a predetermined number (the counter value corresponding to the type of special symbol = the number of rounds minus 1, i.e., the number of rounds in a big winning game) as the counter value in the special electric device maximum operation count counter.

[0462] (Step S660-19) The main CPU 300a sets the special game management phase to 07H, and ends the special prize opening closure validity processing.

[0463] (Step S660-21) The main CPU 300a executes an ending time setting process for saving the ending time in a special game timer.

[0464] (Step S660-23) The main CPU 300a updates the special game management phase to a value obtained by adding 01H to the current value ("06H" or "0AH").

[0465] (Step S660-25) The main CPU 300a sets an ending designation command indicating the start of the ending in the transmission buffer, and ends the big prize opening closure validity processing.

[0466] 43 is a flow chart for explaining the special prize opening end wait process in the main control board 300. This special prize opening end wait process is executed when the special game management phase is "06H" or "0AH".

[0467] (Step S670-1) The main CPU 300a judges whether the timer value of the special game timer saved in the above step S660-7 is "0". If it is judged that the timer value of the special game timer is not "0", the main CPU 300a ends the waiting process for the end of the special winning port, and if it is judged that the timer value of the special game timer is "0", the process proceeds to step S670-3.

[0468] (Step S670-3) The main CPU 300a loads the information stored in the spare area in the above step S631-21. Here, the counter values ​​of the time-saving state flag indicating the game state, the time-saving cut counter, the small win count (Z3) counter, and the small win count (Z4) counter are loaded.

[0469] (Step S670-5) The main CPU300a executes a state setting process for setting the game state after the end of the big prize game executed based on the game ball entering the specific area 140b in the small prize game. Specifically, the main CPU300a saves the information loaded in the above step S670-3 in the time-saving state flag and various counters. This sets the game state after the end of the big prize game, the number of time-saving times, the number of small prize time-saving end operations (Z3), and the number of small prize time-saving end operations (Z4).

[0470] In addition, if the game ball does not enter the specific area 140b in the small winning game, that is, if the special game management phase is "06H", the game state is not set in the step S670-5.

[0471] Also, here, a process is performed to set a variable state after the end of the big win game based on the small win symbol that triggered the execution of the small win game and the setting value being set.

[0472] In this embodiment, when the small winning symbol is stopped and displayed, the game state after the big winning game and the counter value indicating the number of times of various times, which are the time-saving end conditions, are stored in the reserve area, and after the big winning game, the information stored in the reserve area is loaded and transferred as it is. However, when the small winning symbol is stopped and displayed, either one or both of the game state at the time of winning the small winning and the type of the small winning symbol may be stored in the reserve area, and after the big winning game, the game state and counter value to be set after the big winning game may be determined based on the information stored in the reserve area. In any case, it is sufficient that the reference information including at least one of information for setting the state after the big winning game and information for determining whether the end condition is established based on the set game state is stored in the reserve area, and the specific content of the reference information is not particularly limited.

[0473] (Step S670-7) The main CPU 300a sets in the transmission buffer a game state change designation command for transmitting the game state and the variable state that are set after the end of the big role game.

[0474] (Step S670-9) The main CPU 300a sets in the transmission buffer a number designation command corresponding to the time-saving number of times saved in step S670-5, the small win time-saving end operation number of times (Z3), and the small win time-saving end operation number of times (Z4).

[0475] (Step S670-11) The main CPU300a updates the special game management phase to "00H" and ends the waiting process for the end of the special winning port. As a result, if the special 1 reserve or special 2 reserve is stored, the variable display of the special symbol is resumed.

[0476] 44 is a diagram explaining the normal game management phase. As already explained, in the embodiment, the processing related to the normal game triggered by the passage of the game ball through the gate 124 is executed stepwise and repeatedly, and the main control board 300 manages each processing related to such normal games by the normal game management phase.

[0477] As shown in FIG. 44, the main ROM 300b stores a plurality of normal game control modules for controlling the execution of a normal game, and each of these normal game control modules is associated with a normal game management phase. Specifically, when the normal game management phase is "00H", a module for executing "normal symbol change waiting process" is called, when the normal game management phase is "01H", a module for executing "normal symbol change in progress process" is called, when the normal game management phase is "02H", a module for executing "normal symbol stop symbol display process" is called, when the normal game management phase is "03H", a module for executing "normal electric role winning opening pre-processing" is called, when the normal game management phase is "04H", a module for executing "normal electric role winning opening opening control process" is called, when the normal game management phase is "05H", a module for executing "normal electric role winning opening closing valid process" is called, and when the normal game management phase is "06H", a module for executing "normal electric role winning opening end wait process" is called.

[0478] FIG. 45 is a flow chart for explaining the normal game management process (step S700) in the main control board 300.

[0479] (Step S700-1) The main CPU 300a loads the normal game management phase.

[0480] (Step S700-3) The main CPU 300a selects the normal game control module corresponding to the normal game management phase loaded in the above step S700-1.

[0481] (Step S700-5) The main CPU 300a calls the normal game control module selected in step S700-3 and starts processing.

[0482] (Step S700-7) The main CPU 300a loads a normal game timer that manages the control time of a normal game.

[0483] 46 is a flowchart explaining the normal symbol change waiting process in the main control board 300. This normal symbol change waiting process is executed when the normal game management phase is "00H".

[0484] (Step S710-1) The main CPU300a loads the counter value of the normal symbol reserved ball number counter and judges whether the counter value is "0", that is, whether the normal symbol reserved is "0". If it is judged that the counter value is "0", the normal symbol change waiting process is terminated, and if it is judged that the counter value is not "0", the process is transferred to step S710-3.

[0485] (Step S710-3) The main CPU 300a transfers the regular symbol reserve (win-determining random numbers) stored in the first to fourth storage sections of the regular symbol reserve storage area in blocks to the storage section with the next smaller ordinal number. Specifically, the regular symbol reserve stored in the second to fourth storage sections is transferred to the first to third storage sections. The main RAM 300c is also provided with a 0th storage section to be processed, and the regular symbol reserve stored in the 1st storage section is transferred to the 0th storage section. In addition, in this regular symbol storage area shift process, the counter value of the regular symbol reserved ball count counter is decremented by "1," and a regular symbol reserve decrement command indicating that the regular symbol reserve has been decremented by "1" is set in the transmission buffer.

[0486] (Step S710-5) The main CPU 300a loads the winning determination random number transferred to the 0th memory unit, selects a winning determination random number judgment table corresponding to the current game state, performs a regular symbol lottery, and executes a regular symbol winning determination process that stores the lottery result.

[0487] (Step S710-7) The main CPU300a saves the normal symbol stop symbol number corresponding to the result of the normal symbol lottery in step S710-5. In the embodiment, the normal symbol display 168 is composed of one LED lamp, and in the case of a win, the normal symbol display 168 is turned on, and in the case of a loss, the normal symbol display 168 is turned off. The normal symbol stop symbol number determined here indicates whether or not the normal symbol display 168 is ultimately turned on. For example, in the case of a win, "0" is determined as the normal symbol stop symbol number, and in the case of a loss, "1" is determined as the normal symbol stop symbol number.

[0488] (Step S710-9) The main CPU 300a checks the current game state, and selects and sets the corresponding normal symbol variation time data table.

[0489] (Step S710-11) The main CPU 300a determines the normal symbol variation time based on the winning determination random number transferred to the 0th memory unit in the above step S710-3 and the normal symbol variation time data table set in the above step S710-9.

[0490] (Step S710-13) The main CPU 300a saves the normal symbol variation time determined in the above step S710-11 in the normal game timer.

[0491] (Step S710-15) The main CPU 300a executes a process of setting the normal symbol display symbol counter in order to start the variable display of the normal symbol in the normal symbol display 168. When the counter value is set to, for example, "0" in the normal symbol display symbol counter, the normal symbol display 168 is controlled to be turned on, and when the counter value is set to "1", the normal symbol display 168 is controlled to be turned off. Here, a predetermined counter value is set in the normal symbol display symbol counter at the start of the variable display of the normal symbol.

[0492] (Step S710-17) The main CPU 300a sets a regular map reservation designation command indicating the number of regular map reservations stored in the regular map reservation memory area in a transmission buffer.

[0493] (Step S710-19) The main CPU 300a sets a normal symbol designation command in the transmission buffer based on the normal symbol stop symbol number determined in step S710-7 above, i.e., the symbol type (winning symbol or losing symbol) determined by the normal symbol winning determination process.

[0494] (Step S710-21) The main CPU 300a updates the normal game management phase to "01H" and ends the normal symbol change waiting process.

[0495] 47 is a flowchart explaining the normal symbol variation processing in the main control board 300. This normal symbol variation processing is executed when the normal game management phase is "01H".

[0496] (Step S720-1) The main CPU 300a judges whether the timer value of the normal game timer saved in the above step S710-13 is "0". If the timer value is "0", the process proceeds to step S720-9. If the timer value is not "0", the process proceeds to step S720-3.

[0497] (Step S720-3) The main CPU 300a updates the normal symbol display timer that measures the lighting time and the extinguishing time of the normal symbol display 168. Specifically, if the timer value of the normal symbol display timer is "0", a predetermined timer value is set, and if the timer value is "1" or more, the timer value is updated to a value obtained by subtracting "1" from the current timer value.

[0498] (Step S720-5) The main CPU300a judges whether the timer value of the normal symbol display timer is "0". As a result, if it is judged that the timer value of the normal symbol display timer is "0", the process proceeds to step S720-7, and if it is judged that the timer value of the normal symbol display timer is not "0", the process during the normal symbol variation is terminated.

[0499] (Step S720-7) The main CPU 300a updates the counter value of the normal symbol display symbol counter. Here, if the counter value of the normal symbol display symbol counter is a counter value indicating that the normal symbol display 168 is turned off, it is updated to a counter value indicating that the normal symbol display 168 is turned on, and if the counter value is a counter value indicating that the normal symbol display 168 is turned on, it is updated to a counter value indicating that the normal symbol display 168 is turned off, and the normal symbol variation process is terminated. As a result, the normal symbol display 168 is turned on and off repeatedly (blinks) at predetermined intervals during the normal symbol variation time.

[0500] (Step S720-9) The main CPU 300a saves the normal symbol stop symbol number (counter value) determined in step S710-7 in the normal symbol display symbol counter. As a result, the normal symbol display 168 is finally controlled to be turned on or off, and the result of the normal symbol lottery is announced.

[0501] (Step S720-11) The main CPU 300a sets a normal symbol variation stop time, which is the time for stopping and displaying the normal symbols, in a normal game timer.

[0502] (Step S720-13) The main CPU 300a sets a normal symbol stop command, which indicates that the stopped display of normal symbols has begun, in the transmission buffer.

[0503] (Step S720-15) The main CPU 300a updates the normal game management phase to "02H" and ends the normal pattern variation processing.

[0504] 48 is a flowchart explaining the normal symbol stop symbol display process in the main control board 300. This normal symbol stop symbol display process is executed when the normal game management phase is "02H".

[0505] (Step S730-1) The main CPU 300a judges whether the timer value of the normal game timer set in the above step S720-11 is not "0". As a result, if it is judged that the timer value of the normal game timer is not "0", the normal pattern stop symbol display process is terminated, and if it is judged that the timer value of the normal game timer is "0", the process proceeds to step S730-3.

[0506] (Step S730-3) The main CPU 300a checks the result of the regular drawing.

[0507] (Step S730-5) The main CPU 300a judges whether the result of the normal drawing is a win or not. If it is judged to be a win, the process proceeds to step S730-9, and if it is judged to be a no win (miss), the process proceeds to step S730-7.

[0508] (Step S730-7) The main CPU300a updates the normal game management phase to "00H" and ends the normal symbol stop symbol display process. This ends the normal game management process based on the normal symbol reservation of 1, and if the normal symbol reservation is stored, processing is performed to start the variable display of the normal symbol based on the next reservation.

[0509] (Step S730-9) The main CPU 300a refers to the data in the opening / closing control pattern table, and saves the time before normal power opening in the normal game timer as a timer value.

[0510] (Step S730-11) The main CPU300a updates the normal game management phase to "03H" and ends the normal symbol stop symbol display process. This starts the opening and closing control of the second start port 122.

[0511] 49 is a flowchart explaining the normal electric device winning opening pre-processing in the main control board 300. This normal electric device winning opening pre-processing is executed when the normal game management phase is "03H".

[0512] (Step S740-1) The main CPU300a judges whether the timer value of the normal game timer is not "0". As a result, if it is judged that the timer value of the normal game timer is not "0", the normal electric role winning opening pre-opening process is terminated, and if it is judged that the timer value of the normal game timer is "0", the process is transferred to step S741.

[0513] (Step S741) The main CPU 300a executes a normal electric accessory winning mouth opening / closing switching process, which will be described later.

[0514] (Step S740-3) The main CPU 300a updates the normal game management phase to "04H" and ends the normal electric role winning opening pre-opening process.

[0515] 50 is a flowchart explaining the normal electric role winning opening opening / closing switching process in the main control board 300.

[0516] (Step S741-1) The main CPU 300a judges whether the counter value of the normal electric role opening / closing switching counter is the upper limit value of the normal electric role opening / closing switching count (the number of times the movable piece 122b opens and closes during one opening / closing control). If it is judged that the counter value is the upper limit value, the normal electric role winning opening opening / closing switching process is terminated, and if it is judged that the counter value is not the upper limit value, the process proceeds to step S741-3.

[0517] (Step S741-3) The main CPU 300a refers to the data in the opening / closing control pattern table and extracts solenoid control data (energization control data or de-energization control data) for controlling the energization of the normal electric role solenoid 122c based on the counter value of the normal electric role opening / closing switching count counter, and timer data which is the energization time (solenoid energization time) or de-energization time (normal power closing effective time = pause time) of the normal electric role solenoid 122c.

[0518] (Step S741-5) The main CPU 300a executes a normal electric role solenoid energization control process to start energizing the normal electric role solenoid 122c or stop energizing the normal electric role solenoid 122c based on the solenoid control data extracted in the above step S741-3. By executing this normal electric role solenoid energization control process, the normal electric role solenoid 122c is controlled to start or stop energizing in the above step S400-31 and step S400-33.

[0519] (Step S741-7) The main CPU 300a saves the timer value based on the timer data extracted in the above step S741-3 in the normal game timer. The timer value saved in the normal game timer here is the maximum opening time of the second start port 122 once.

[0520] (Step S741-9) The main CPU 300a judges whether the normal electric role solenoid 122c is in the energization start state, that is, whether the control process to start energization of the normal electric role solenoid 122c has been performed in the above step S741-5. As a result, if it is judged to be in the energization start state, the process is transferred to step S741-11, and if it is judged not to be in the energization start state, the normal electric role winning opening opening switching process is terminated.

[0521] (Step S741-11) The main CPU 300a updates the counter value of the normal electric accessory opening / closing switching number counter to a value obtained by adding "1" to the current counter value.

[0522] 51 is a flowchart explaining the normal electric accessory winning port opening control process in the main control board 300. This normal electric accessory winning port opening control process is executed when the normal game management phase is "04H".

[0523] (Step S750-1) The main CPU 300a judges whether the timer value of the normal game timer saved in the above step S741-7 is "0". As a result, if it is judged that the timer value of the normal game timer is not "0", the process proceeds to step S750-5, and if it is judged that the timer value of the normal game timer is "0", the process proceeds to step S750-3.

[0524] (Step S750-3) The main CPU 300a judges whether the counter value of the normal electric role opening / closing switching counter is the upper limit value of the normal electric role opening / closing switching count. If it is judged that the counter value is the upper limit value, the process proceeds to step S750-7, and if it is judged that the counter value is not the upper limit value, the process proceeds to step S741.

[0525] (Step S741) In the above step S750-3, if it is determined that the counter value of the normal electric role opening / closing switching count counter is not the upper limit value of the normal electric role opening / closing switching count, the main CPU 300a executes the process of the above step S741.

[0526] (Step S750-5) The main CPU 300a judges whether the counter value of the normal electric device winning ball counter updated in the above step S530-9 has reached a specified number, that is, whether the same number of game balls as the maximum number of winning balls during one opening and closing control have entered the second starting hole 122. As a result, if it is judged that the specified number has not been reached, the normal electric device winning hole opening control process is terminated, and if it is judged that the specified number has been reached, the process proceeds to step S750-7.

[0527] (Step S750-7) The main CPU 300a executes a normal electric accessory closing process required to stop the power supply to the normal electric accessory solenoid 122c and close the second start port 122. This causes the second start port 122 to be in a closed state.

[0528] (Step S750-9) The main CPU 300a saves the normal power effective state time in the normal game timer.

[0529] (Step S750-11) The main CPU 300a updates the normal game management phase to "05H" and ends the normal electric role winning port opening control process.

[0531] (Step S760-1) The main CPU 300a judges whether the timer value of the normal game timer saved in the above step S750-9 is not "0". As a result, if it is judged that the timer value of the normal game timer is not "0", the normal electric role winning port closing valid processing is terminated, and if it is judged that the timer value of the normal game timer is "0", the processing is transferred to step S760-3.

[0532] (Step S760-3) The main CPU 300a saves the normal power end wait time in the normal game timer.

[0533] (Step S760-5) The main CPU 300a updates the normal game management phase to "06H" and ends the normal electric role winning hole closure validity processing.

[0534] 53 is a flowchart explaining the normal electric accessory winning port end wait processing in the main control board 300. This normal electric accessory winning port end wait processing is executed when the normal game management phase is "06H".

[0535] (Step S770-1) The main CPU300a judges whether the timer value of the normal game timer saved in the above step S760-3 is not "0". As a result, if it is judged that the timer value of the normal game timer is not "0", the normal electric role winning port end wait process is terminated, and if it is judged that the timer value of the normal game timer is "0", the process proceeds to step S770-3.

[0536] (Step S770-3) The main CPU 300a updates the normal game management phase to "00H" and ends the normal electric role winning port end wait process. As a result, if a normal symbol reservation is stored, the variable display of the normal symbol will be resumed.

[0537] As described above, various processes are executed in the main control board 300, whereby the special game and the normal game progress, and the gameplay shown in FIG. 18 is realized.

[0538] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such an embodiment. It is obvious that a person skilled in the art can think of various modifications or alterations within the scope of the claims, and it is understood that such modifications also belong to the technical scope of the present invention.

[0539] In the above embodiment, an example of the case where the present invention is applied to a second type gaming machine has been described, but the gameplay of the gaming machine to which the present invention can be applied is not limited to this. For example, it goes without saying that the present invention can also be applied to a first type gaming machine and a first type / second type mixed machine. Therefore, in the above embodiment, a case where a big win symbol is not provided has been described, but a big win symbol may be provided separately from a small win symbol. When a big win symbol is stopped and displayed, a big role game is executed without going through a small win game. For example, in the special 1 reservation, a small win symbol may not be provided and only a big win symbol may be provided. When a big win symbol is provided, the processing such as setting a reserve area and setting a game state, which is executed when a small win symbol is won in the above embodiment, may also be applied to the big win symbol.

[0540] In the above embodiment, the case where three modes (first lower mode, second lower mode, and higher mode) with different advantageous degrees are provided as the time-saving game state has been described. However, the first lower mode and the second lower mode may have a common advantageous degree. In addition, the game progress conditions in each state are not particularly limited.

[0541] In the above embodiment, four small win symbols are provided, and the state set differs depending on the type of the small win symbol. However, the number and type of the small win symbols can be set as appropriate.

[0542] In addition, the time-saving end conditions in the above embodiment are merely examples. For example, in the above embodiment, the time-saving end conditions are the number of times of time-saving, the number of times of small win time-saving end operation (Z3), and the number of times of small win time-saving end operation (Z4), but only some of these may be provided.

[0543] In the above embodiment, when a small win is won by the special 2 reservation, the special pattern Z3 is determined with a probability of 50%, and the special pattern Z4 is determined with a probability of 50%, but the probability of determining the special patterns Z3 and Z4 may be changed. For example, when a small win is won by the special 2 reservation, the probability of determining the special pattern Z3 (e.g., 80%) may be higher than the probability of determining the special pattern Z4 (e.g., 20%). By doing so, it is possible to make the probability of transitioning from the first lower mode to the second lower mode after the end of the big role game (e.g., 20%) lower than the probability of the first lower mode being reset after the end of the big role game (e.g., 80%). Also, it is possible to make the probability of transitioning from the second lower mode to the higher mode after the end of the big role game (e.g., 20%) lower than the probability of transitioning from the second lower mode to the first lower mode after the end of the big role game (e.g., 80%). This makes it possible to set the difficulty level for transitioning to a mode with a higher degree of advantage relatively high, and to provide the player with a special feeling of transitioning to a mode with a higher degree of advantage.

[0544] Also, for example, when a small win is won by the special 2 reservation, the probability that the special symbol Z3 is determined (for example, 20%) may be lower than the probability that the special symbol Z4 is determined (for example, 80%). By doing so, it is possible to make the probability that the first lower mode is shifted to the second lower mode after the end of the big role game (for example, 80%) higher than the probability that the first lower mode is reset after the end of the big role game (for example, 20%). Also, it is possible to make the probability that the second lower mode is shifted to the higher mode after the end of the big role game (for example, 80%) higher than the probability that the second lower mode is shifted to the first lower mode after the end of the big role game (for example, 20%). This makes it possible to set the difficulty level of shifting to a mode with a high degree of advantage relatively low, and since it is relatively easy to shift to a mode with a high degree of advantage, it is possible to stimulate the player's desire to play.

[0545] In any case, when the starting condition is satisfied, the game machine is provided with a determination means (main CPU300a executing the process of FIG. 34) for deriving one of a plurality of determination results including at least a winning result (special symbol Z3, special symbol Z4) and a losing result, and a game state setting means (main CPU300a executing the process of step S670-5) for setting one of a plurality of game states, in which the game states include a normal game state (non-time-shortened game state) and a time-shortened game state, and the time-shortened game state includes a predetermined time-shortened game state (first lower mode) which is more advantageous than the normal game state (non-time-shortened game state) and a specific time-shortened game state (higher mode) which is more advantageous than the predetermined time-shortened game state (first lower mode), and the winning result (special symbol Z3, special symbol Z4) is determined by a determination means (main CPU300a executing the process of FIG. 34) for deriving one of a plurality of determination results including at least a winning result (special symbol Z3, special symbol Z4), and a game state setting means (main CPU300a executing the process of step S670-5) for setting one of a plurality of game states. includes a specific winning result (special pattern Z4) and a predetermined winning result (special pattern Z3) different from the specific winning result (special pattern Z4), and the game state setting means is capable of setting a specific time-saving game state (higher mode) after the second winning result is derived when a specific winning result (special pattern Z4) is derived twice consecutively in the next two winning results after a specific time-saving game state (first lower mode) is set, and is capable of setting a specific time-saving game state (first lower mode) after the second winning result (special pattern Z3) is derived when a specific winning result (special pattern Z4) is derived in the next two winning results after a specific time-saving game state (first lower mode) is set.

[0546] Furthermore, the game state setting means may not set a time-saving game state (first lower mode, second lower mode) in which the degree of advantage decreases after the winning result (special pattern Z3, special pattern Z4) is derived in a specific time-saving game state (higher mode).

[0547] Furthermore, the processing in the main control board 300 shown in the above embodiment is merely an example, and the order and content of the processing can be modified as appropriate.

[0548] In addition, the type of the special symbol that is won and the game state setting that is set according to the game state at the time of winning are not limited to the example shown in the above embodiment. Below, modified examples of the game state setting that is set according to the type of the special symbol that is won and the game state at the time of winning are shown.

[0549] Fig. 54 is a diagram for explaining a game state setting table for setting the game state after the end of the big win game according to the modified example. The game state setting table shown in Fig. 54 is used in place of the game state setting table (Fig. 15) in the above embodiment. Below, only the points different from the game state setting table (Fig. 15) in the above embodiment will be described.

[0550] As shown in Fig. 54, according to the game state setting table of the modified example, when the special symbol Z4 is determined as the small win symbol and the game state at the time of winning the small win is a non-time-saving game state, the game state after the big win is set to the time-saving game state and the second lower mode is set. As shown in Fig. 54, in the modified example, the time-saving end conditions of the second lower mode are set as the time-saving number of times 50, the small win time-saving end operation number (Z3) 0, and the small win time-saving end operation number (Z4) 1.

[0551] FIG. 55 is a diagram for explaining the gameplay according to the modified example. In the following, the case where the player appropriately launches the game ball and the game proceeds in accordance with the original gameplay, that is, the case where the game continues normally, will be mainly explained, and the case where an irregular situation occurs will basically be omitted. In addition, the case where the game continues normally refers to the case where the player plays the game in accordance with the original gameplay, and indicates the case where irregular situations such as various errors and game stoppages do not occur. In the following, only the points that are different from the gameplay in the above embodiment (FIG. 18) will be explained.

[0552] As shown in (3) of Figure 55, in the second lower mode of the modified example, the conditions for ending the time-saving feature are set as follows: the number of times that the time-saving feature is activated is 50, the number of times that the small win time-saving feature is activated is 0, and the number of times that the small win time-saving feature is activated is 1.

[0553] In the second lower mode, when a small win is won by the special 2 reservation, the special symbol Z3 is determined with a probability of 50%, and a small win game based on the special symbol Z3 is executed. In the small win game based on the special symbol Z3, since the game ball can enter the specific area 140b, the big role game is executed following the small win game. At this time, in the embodiment, the player can obtain a total of 450 prize balls in the small win game and the big role game. Also, when the special symbol Z3 is won in the second lower mode, the time-saving end condition based on the small win time-saving end operation number (Z3) is not established. That is, when the special symbol Z3 is won in the second lower mode, the game state at the time of winning is a time-saving game state. Therefore, as shown in (4) of FIG. 55, the game state after the big role game is set to the high-order mode as a time-saving game state.

[0554] In addition, in the second lower mode, when a small win is won by the special 2 reservation, the special symbol Z4 is determined with a probability of 50%, and a small win game based on the special symbol Z4 is executed. In the small win game based on the special symbol Z4, since the game ball can enter the specific area 140b, the big role game is executed following the small win game. At this time, in the embodiment, the player can obtain a total of 1500 prize balls in the small win game and the big role game. In addition, when the special symbol Z4 is won in the second lower mode, the time-saving end condition based on the small win time-saving end operation number (Z4) is established. That is, when the special symbol Z4 is won in the second lower mode, the game state at the time of winning becomes a non-time-saving game state. Therefore, as shown in (3) of FIG. 55, the game state after the big role game is reset to the second lower mode as a time-saving game state.

[0555] As described above, in the modified example, in the second lower mode, the probability of being reset to the second lower mode after playing a big role is 50%, and the probability of being set to the higher mode after playing a big role is 50%. That is, in the second lower mode in the modified example, after playing a big role, there is a 50% probability of transitioning to a mode (higher mode) with a higher degree of advantage than the current mode (second lower mode), and there is a 50% probability of resetting to a mode (second lower mode) with the same degree of advantage as the current mode (second lower mode) after playing a big role. In other words, the second lower mode in the modified example has a new playability in which the current mode (second lower mode) does not transition to a mode with a lower degree of advantage after playing a big role, making it possible to improve the interest of the game.

[0556] In addition, in the modified example, when a specific winning result (special pattern Z4) is derived in the first lower mode, a transition to the second lower mode is made, and when a predetermined winning result (special pattern Z3) is derived in the second lower mode, a transition to the higher mode is made, thereby providing new gameplay properties and making the game more interesting.

[0557] In addition, in the modified example, regardless of which winning result (special pattern Z3, special pattern Z4) is derived in the first lower mode, the second lower mode, or the higher mode, a time-saving game state in which the degree of advantage is reduced is not set, thereby providing new gameplay properties and making the game more interesting.

[0558] In the modified example, when a small win is won by the special 2 reservation, the special symbol Z3 is determined with a probability of 50%, and the special symbol Z4 is determined with a probability of 50%, but the probability of determining the special symbols Z3 and Z4 may be changed. For example, when a small win is won by the special 2 reservation, the probability of determining the special symbol Z3 (e.g., 80%) may be higher than the probability of determining the special symbol Z4 (e.g., 20%). By doing so, it is possible to make the probability of shifting from the first lower mode to the second lower mode after the end of the big role game (e.g., 20%) lower than the probability of shifting from the second lower mode to the higher mode after the end of the big role game (e.g., 80%). This makes it possible to provide a gameplay in which the first lower mode is shifted to the second lower mode with a relatively high degree of difficulty, and the second lower mode is shifted to the higher mode with a relatively low degree of difficulty. Then, it is possible to make the advantage of the second lower mode higher than that of the first lower mode, and to improve the interest of the game.

[0559] Also, for example, when a small win is won by the special 2 reservation, the probability that the special symbol Z3 is determined (for example, 20%) may be lower than the probability that the special symbol Z4 is determined (for example, 80%). By doing so, it is possible to make the probability that the first lower mode will shift to the second lower mode after the big role game is over (for example, 80%) higher than the probability that the second lower mode will shift to the higher mode after the big role game is over (for example, 20%). This makes it possible to provide a game in which the first lower mode is shifted to the second lower mode at a relatively low level of difficulty, and the second lower mode is shifted to the higher mode at a relatively high level of difficulty, and it is possible to provide the player with a special feeling of shifting to the higher mode.

[0560] In any case, when the starting condition is established, the game machine is provided with a determination means (main CPU300a executing the process of FIG. 34) for deriving one of a plurality of determination results including at least a winning result (special symbol Z3, special symbol Z4) and a losing result, and a game state setting means (main CPU300a executing the process of step S670-5) for setting one of a plurality of game states, and the game state includes a normal game state (non-time-shortened game state) and a time-shortened game state, and the time-shortened game state includes a predetermined time-shortened game state (first lower mode) which is more advantageous than the normal game state (non-time-shortened game state) and a predetermined time-shortened game state (first lower mode). The game state setting means may set a specific time-saving game state (higher mode) which is more advantageous than the specific time-saving game state (first lower mode), and the winning results (special pattern Z3, special pattern Z4) include a specific winning result (special pattern Z4) and a predetermined winning result (special pattern Z3) different from the specific winning result (special pattern Z4). After the predetermined time-saving game state (first lower mode) is set, when a specific winning result (special pattern Z4) is derived in the next two winning results and then a predetermined winning result (special pattern Z3) is derived, the game state setting means may set a specific time-saving game state (higher mode) after the second winning result (special pattern Z3) is derived.

[0561] Furthermore, the game state setting means does not have to set a time-saving game state in which the degree of advantage decreases after the derivation of any winning result (special pattern Z3, special pattern Z4) in the time-saving game state (first lower mode, second lower mode, higher mode).
