[0012] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. The dimensions, materials, and other specific numerical values ​​shown in these embodiments are merely examples to facilitate understanding of the invention and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals to avoid redundant explanations, and elements not directly related to the present invention are omitted from the illustrations.

[0013] To facilitate understanding of the embodiments of the present invention, the mechanical and electrical configurations of the gaming machine according to this embodiment, as well as the specific processing on each circuit board, will be described.

[0014] Figure 1 is a perspective view of the gaming machine 100 according to this embodiment, showing the door in an open state. As shown in the figure, the gaming machine 100 comprises an outer frame 102 in which a surrounding space is formed by four sides arranged in a substantially rectangular shape, an inner frame 104 attached to the outer frame 102 so as to be openable and closable by a hinge mechanism, and a front frame 106 attached to the inner frame 104 so as to be openable and closable by a hinge mechanism.

[0015] The inner frame 104, like the outer frame 102, has a surrounding space formed by four sides arranged in a roughly rectangular shape, and the game board 108 is held in this surrounding space. The front frame 106 holds a glass or resin transparent plate 110. When these inner frame 104 and front frame 106 are closed relative to the outer frame 102, the game board 108 and the transparent plate 110 face each other roughly parallel to maintain a predetermined distance, and the game board 108 becomes visible from the front side of the gaming machine 100 through the transparent plate 110.

[0016] Figure 2 is a front view of the gaming machine 100 according to this embodiment. As shown in this figure, an operating handle 112 is provided at the lower part of the front frame 106, protruding towards the front of the gaming machine 100. This operating handle 112 is provided so that it can be rotated by the player, and when the player rotates the operating handle 112 to perform a launching operation, a game ball is launched by a launching mechanism (not shown) with a force corresponding to the rotation angle of the operating handle 112. The game ball launched in this manner rises between rails 114a and 114b provided on the game board 108 and is guided to the game area 116.

[0017] The game area 116 is a space formed between the game board 108 and the permeable plate 110, and is an area in which game balls can flow or roll. The game board 108 is equipped with numerous nails and windmills, and game balls guided into the game area 116 collide with the nails and windmills, causing them to flow or roll in irregular directions.

[0018] The game area 116 comprises a first game area 116a and a second game area 116b, which differ in the degree to which game balls enter each other depending on the launch strength of the launching mechanism. The first game area 116a is located on the left side of the game area 116 as viewed from a player facing the game machine 100, and the second game area 116b is located on the right side of the game area 116 as viewed from a player facing the game machine 100. Since the rails 114a and 114b are on the left side of the game area 116, game balls launched by the launching mechanism with a launch strength below a predetermined strength enter the first game area 116a, and game balls launched with a launch strength of a predetermined strength or greater enter the second game area 116b.

[0019] Furthermore, the game area 116 is provided with a general prize entry point 118, a first start entry point 120, and a second start entry point 122 into which game balls can be entered. When a game ball enters one of these general prize entry points 118, the first start entry point 120, or the second start entry point 122, a predetermined number of prize balls are dispensed to the player. The number of prize balls dispensed can be any number, one or more, and the number of prize balls dispensed from each of the general prize entry point 118, the first start entry point 120, and the second start entry point 122 may be different or the same. In this case, it is also possible to set the number of prize balls dispensed when a game ball enters the first start entry point 120 to be less than the number of prize balls dispensed when a game ball enters the second start entry point 122.

[0020] As will be explained in more detail later, a first starting area is provided within the first starting opening 120, and a second starting area is provided within the second starting opening 122. When a game ball enters the first starting opening 120 or the second starting opening 122 and enters the first starting area or the second starting area, a lottery is held to determine one of several pre-determined special symbols. Each special symbol is associated with various game benefits, such as whether or not a major or minor winning game that is advantageous to the player can be performed, or what kind of game state the subsequent game will be in. Therefore, when a game ball enters the first starting opening 120 or the second starting opening 122, the player not only wins a predetermined prize ball, but also gains the opportunity to acquire the right to receive various game benefits.

[0021] The first starting opening 120 is located below the game area 116, and is positioned such that only game balls flowing down the first game area 116a can enter it, or it is positioned in a way that makes it easier for game balls that have entered the first game area 116a to enter than for game balls that have entered the second game area 116b.

[0022] Furthermore, the second starting port 122 is located in the second game area 116b, and only game balls flowing down the second game area 116b can enter it, or it is positioned so that game balls entering the second game area 116b are more likely to enter than game balls entering the first game area 116a. This second starting port 122 is composed of a variable starting port (variable starting prize entry device) having a movable piece 122b, so that the ease with which game balls can enter the second starting port 122 is variable.

[0023] Specifically, the second starting opening 122 is provided with a movable piece 122b that can be opened and closed, and when this movable piece 122b is in the closed position, it is impossible or difficult for game balls to enter the second starting opening 122. The specific configuration of the second starting opening 122 is not particularly limited, but here, the movable piece 122b is assumed to be retracted into the rear side of the game board 108 when in the closed position, and to protrude into the front side of the game board 108 when in the open position. When the movable piece 122b is retracted and in the closed position, the second starting opening 122 is closed, and game balls flow down the front side of the second starting opening 122.

[0024] In response to this, when a game ball passes through the gate 124 provided in the first game area 116a and the second game area 116b, or when a game ball enters the regular symbol operation opening 125 provided in the second game area 116b, it is determined whether or not to perform an auxiliary game in which the second start opening 122 is opened. If it is determined that the auxiliary game should be performed, an auxiliary game is executed in which the second start opening 122 is opened and closed. More specifically, a lottery for regular symbols, described later, is performed based on whether a game ball has passed through the gate 124 or entered the regular symbol operation opening 125. If a winning combination is selected in this lottery, the movable piece 122b is controlled to be open for a predetermined time.

[0025] When the movable piece 122b is in the open position, the game balls flowing down the front side of the second start opening 122 fall onto the movable piece 122b. The game balls that fall onto the movable piece 122b are guided by the movable piece 122b and led to the second start opening 122. In this way, when the movable piece 122b is in the open position, it functions as a receptacle that guides the game balls to the second start opening 122, making it easier for the game balls to enter the second start opening 122.

[0026] Furthermore, a first large prize opening 126 and a second large prize opening 128 are provided at the bottom of the game area 116. The first large prize opening 126 and the second large prize opening 128 are positioned so that game balls flowing down the second game area 116b can enter them. The first large prize opening 126 is provided with an opening / closing door 126b that can be opened and closed. Normally, the opening / closing door 126b closes the first large prize opening 126, making it impossible for game balls to enter the first large prize opening 126. However, when the aforementioned small prize game is played, the opening / closing door 126b is opened and functions as a receiving tray, making it possible for game balls to enter the first large prize opening 126. When a game ball enters the first large prize opening 126, a predetermined amount of prize balls is paid out to the player.

[0027] Furthermore, the second major prize slot 128 is equipped with an opening / closing door 128b that can be opened and closed. Normally, the opening / closing door 128b closes the second major prize slot 128, making it impossible for game balls to enter it. However, when the aforementioned major prize game is performed, the opening / closing door 128b opens and functions as a receiving tray, allowing game balls to enter the second major prize slot 128. When game balls enter the second major prize slot 128, a predetermined amount of prize balls are paid out to the player. The first major prize slot 126 and the second major prize slot 128 are collectively referred to simply as the major prize slots.

[0028] Furthermore, at the bottom of the game area 116, there is an outlet 130 for discharging game balls that did not enter any of the general prize entry points 118, the first start entry point 120, the second start entry point 122, the first major prize entry point 126, or the second major prize entry point 128 from the game area 116 to the back side of the game board 108.

[0029] Furthermore, the gaming machine 100 is equipped with a performance device that performs effects during gameplay, including a performance display device 200 consisting of a liquid crystal display, a performance mechanism device 202 consisting of a movable device, a performance lighting device 204 consisting of lamps that can be controlled to various lighting patterns and colors, an audio output device 206 consisting of a speaker, and performance buttons 208 that accept input from the player.

[0030] The performance display device 200 comprises a main performance display unit 200a and a sub-performance display unit 201a, both consisting of an image display unit for displaying images. The main performance display unit 200a is positioned approximately in the center of the game board 108, visible from the front of the game machine 100. As shown in the figure, performance symbols 210a, 210b, and 210c are displayed in this main performance display unit 200a in a variable manner, and a variable performance is executed in which the result of the big win lottery is notified to the player based on the stopping display pattern of each of these performance symbols 210a, 210b, and 210c. The sub-performance display unit 201a is provided above the main performance display unit 200a and displays auxiliary performance images during the variable performance.

[0031] The special effects device 202 is positioned in front of the main display unit 200a and is normally retracted to the back of the game board 108. However, during the display of the above-mentioned special effects symbols 210a, 210b, and 210c, it moves to the front of the main display unit 200a to give the player a sense of anticipation for a big win.

[0032] The special effects lighting device 204 is installed on the special effects mechanism 202, the game board 108, etc., and is controlled to light up in various ways in accordance with the images displayed on the main special effects display unit 200a.

[0033] The audio output device 206 is located at the top of the front frame 106 and at the bottom of the outer frame 102, and outputs various sounds toward the front of the gaming machine 100 in accordance with the images and other information displayed on the main display unit 200a.

[0034] The performance button 208 is a button that accepts a press operation from the player and is located approximately in the center of the width direction of the gaming machine 100 and below the transparent plate 110. This performance button 208 is activated in accordance with the image displayed on the main performance display unit 200a, and when the player's operation is accepted within the valid operation time, various performances are executed according to that operation.

[0035] The directional pad 209 consists of four buttons—up, down, left, and right—that accept player input, and is located near the effect button 208. The effect button 208 and the directional pad 209 are sometimes used to adjust various settings.

[0036] In the diagram, reference numeral 132 indicates an upper tray into which prize balls dispensed from the gaming machine 100 and game balls dispensed from the game ball dispensing device are led. When this upper tray 132 is full of game balls, the game balls are led to the lower tray 134. The bottom surface of the lower tray 134 has a ball release hole (not shown) for discharging game balls from the lower tray 134. This ball release hole is normally closed by an opening / closing plate (not shown), but by pressing in the ball release knob 134a, the opening / closing plate slides together with the ball release knob 134a, making it possible to discharge game balls from the ball release hole to the bottom of the lower tray 134.

[0037] Furthermore, the game board 108 is equipped with a first special symbol indicator 160, a second special symbol indicator 162, a first special symbol hold indicator 164, a second special symbol hold indicator 166, a regular symbol indicator 168, a regular symbol hold indicator 170, and a right-hand shooting notification indicator 172, located outside the game area 116 and visible to the player. Each of these indicators 160 to 172 is a device for displaying various situations related to the game, and their details will be described later.

[0038] (Internal configuration of the control system) Figure 3 is a block diagram showing the internal configuration of the control means for controlling the progress of the game according to this embodiment.

[0039] 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 main CPU 300a reads the program stored in the main ROM 300b based on input signals from various detection switches and timers, performs calculations, directly controls various devices and displays, or sends commands to other boards according to the results of the calculations. The main RAM 300c functions as a data work area during calculations performed by the main CPU 300a.

[0040] The gaming machine 100 of this embodiment is broadly divided into two types: a special game which is started by the entry of a game ball into the first start port 120 or the second start port 122, and a normal game which is started by the entry of a game ball through the gate 124 (a game ball entering the normal operation port 125). The main ROM 300b of the main control board 300 stores various programs for running the special game and the normal game, as well as data and tables necessary for each type of game.

A game information output terminal board 312 is connected to this payout control board 310, and various information regarding the progress of the game output from the main control board 300 is output to the hall computer of the amusement parlor via the payout control board 310 and the game information output terminal board 312.

[0051] Furthermore, a payout motor 314 is connected to the payout control board 310 for dispensing game balls stored in the storage unit to the player as prize balls. The payout control board 310 controls the payout motor 314 based on a payout quantity specification command transmitted from the main control board 300 to dispense a predetermined number of prize balls to the player. At this time, the number of game balls dispensed is detected by the payout ball counting switch 316s, and it is determined whether the prize balls that should have been dispensed have been dispensed to the player.

[0052] Furthermore, the payout control board 310 is connected to a tray full detection switch 318s that detects when the lower tray 134 is full. This tray full detection switch 318s is installed in the passage that guides the game balls to be paid out as prize balls to the lower tray 134, and each time a game ball passes through this passage, a game ball detection signal is input to the payout control board 310.

[0053] When the lower tray 134 is filled with more than a predetermined amount of game balls, the game balls accumulate in the passage leading to the lower tray 134, and a game ball detection signal is continuously input from the tray full detection switch 318s to the payout control board 310. When the game ball detection signal is continuously input for a predetermined time, the payout control board 310 determines that the lower tray 134 is full and sends a tray full command to the main control board 300. On the other hand, if the continuous input of the game ball detection signal is interrupted after sending the tray full command, the payout control board 310 determines that the full state has been released and sends a tray full release command to the main control board 300.

[0054] Furthermore, the payout control board 310 is connected to a launch control circuit 320 in a bidirectional manner. When the launch control circuit 320 receives launch control data from the payout control board 310, it authorizes the launch. The launch control circuit 320 is connected to a touch sensor 112s, which is provided on the operating handle 112 and detects when a player touches the operating handle 112, and an operating volume 112a, which detects the operating angle of the operating handle 112. When signals are input from the touch sensor 112s and the operating volume 112a, the launch control circuit 320 controls the launch solenoid 112c provided on the game ball launching device to energize and launch the game ball.

[0055] The sub-control board 330 primarily controls various effects during gameplay and standby. This sub-control board 330 includes a sub-CPU 330a, sub-ROM 330b, sub-RAM 330c, RTC 330d, actuarial unit 340, and display control unit 350, and is connected to the main control board 300 in a one-way communication manner from the main control board 300 to the sub-control board 330.

[0056] The sub-CPU 330a reads the program stored in the sub-ROM 330b based on commands transmitted from the main control board 300 and input signals from the timer, performs calculations, and controls the execution of the performance.

[0057] At this time, the sub-RAM 330c functions as a data work area during the calculation processing of the sub-CPU 330a. The sub-CPU 330a also determines the effect to be executed and sends a command indicating the determined effect to the act unit 340.

[0058] The Act Unit 340 manages the timing of the effects to be executed by the effect display device 200, the effect prop device 202, the effect lighting device 204, and the sound output device 206 based on commands sent from the sub-CPU 330a. For example, the Act Unit 340 sends a message to the display control unit 350 indicating the start of the effect execution. The Act Unit 340 manages the timing of each message transmission to manage the timing of the effects to be displayed on the main effect display unit 200a.

[0059] The display control unit 350 controls the display of images on the main performance display unit 200a and the sub-performance display unit 201a based on messages transmitted from the act unit 340. Specifically, the act unit 340 transmits a message based on the performance that has been decided to be executed, the display control unit 350 receives the message transmitted from the act unit 340, generates an image based on the received message, and displays it on the main performance display unit 200a.

[0060] Furthermore, the sub-control board 330 operates the performance device 202 and controls the lighting of the performance lighting device 204, as well as controlling the audio output to output sound from the audio output device 206. In addition, when an operation detection signal is input from the performance button detection switch 208s, which detects when the performance button 208 is pressed, and the directional key detection switch 209s, which detects when the directional key 209 is pressed, it performs predetermined processing.

[0061] Each circuit board is connected to a power supply board (not shown), and power is supplied to each board from the commercial power supply via the power supply board. The power supply board also has a backup power supply consisting of capacitors. The RTC330d, located on the sub-control board 330, receives power from this backup power supply to measure the current time.

[0062] Figure 4 is an address map of the memory area used by the main CPU 300a according to this embodiment. In Figure 4, addresses are shown in hexadecimal, and "H" indicates a hexadecimal number. As shown in Figure 4, the memory area used by the main CPU 300a includes the memory area allocated to the main ROM 300b (0000H to 2FFFH) and the memory area allocated to the main RAM 300c (F000H to F3FFH).

[0063] The memory area of ​​the main ROM 300b is provided with a used area (0000H~1A7AH) for storing programs and data for controlling the progress of the game, and an unused area (2000H~2BFFH) other than the used area for storing programs and data for performing tests as defined by the gaming machine regulations and for displaying the performance display monitor 184 (including processing for calculating the base ratio to be displayed on the performance display monitor 184).

[0064] The main ROM 300b's usable area includes a program area (0000H~0A89H) where programs for controlling the game's progress are stored, an unused area (0A8AH~0FFFH), and a data area (1000H~1A7AH) where data other than programs is stored. Note that the usable area may be excluded from the unused area (0A8AH~0FFFH).

[0065] The unused area of ​​the main ROM 300b includes a program area (2000H~27FFH) where programs for performing tests stipulated by the gaming machine regulations and for displaying the performance display monitor 184 are stored, and a data area (2800H~2BFFH) where data other than these programs is stored.

[0066] In addition to the used and unused memory areas, the main ROM 300b also includes an unused area (1A7BH~1DFFH), a ROM comment area (1E00H~1EFFH) where arbitrary data such as the program title and version are stored, an unused area (1F00H~1FFFH), an unused area (2C00H~2FBFH), and a program management area (2FC0H~2FFFH) where information necessary for the main CPU 300a to execute the program is stored.

[0067] The memory area of ​​the main RAM 300c is divided into a used area (F000H~F1FFH) that is temporarily used when a program for controlling the progress of the game is being executed, and an unused area (F210H~F228H) that is not used when a program for performing tests as defined by the gaming machine regulations or for displaying the performance display monitor 184 is being executed.

[0068] The main RAM 300c's used area includes a work area (F000H~F12AH) that is temporarily used when a program to control the progress of the game is being executed, an unused area (F12BH~F1D7H), and a stack area (F1D8H~F1FFH) for temporarily saving data while the program to control the progress of the game is being executed. Note that the used area may be excluded from the unused area (F12BH~F1D7H).

[0069] The unused area of ​​the main RAM 300c includes a work area (F210H~F21FH) that is temporarily used when programs for performing tests stipulated by the gaming machine regulations or for displaying the performance display monitor 184 are being executed, and a stack area (F220H~F228H) that temporarily saves data when these programs are being executed.

[0070] Furthermore, in addition to the used and unused memory areas, the main RAM300c also includes unused areas (F200H~F20FH) and unused areas (F229H~F3FFH).

[0071] Thus, the main ROM 300b and main RAM 300c are provided with separate areas for use, which are used to control the progress of the game, and for use, which are used to perform processes for conducting tests as defined by the gaming machine regulations and for controlling the display of the performance display monitor 184.

[0072] Furthermore, 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 separating the used area and the unused area, clearly defining the boundary between the used area and the unused area. This prevents the unused area from being used when a program to control the progress of the game is being executed, and prevents the used area from being used when a program for performing tests stipulated in the gaming machine regulations or for controlling the display of the performance display monitor 184 is being executed.

[0073] The unused area between the used and unused areas only needs to be at least 1 byte, but from a security standpoint, it is preferable to have at least 4 bytes, and even more preferable to have at least 16 bytes. In addition, writing and reading data from the unused area is prohibited, but from a security standpoint, it may be set to be cleared at predetermined intervals.

[0074] Next, the gameplay in the gaming machine 100 of this embodiment will be explained along with the various tables stored in the main ROM 300b.

[0075] As described above, the gaming machine 100 of this embodiment has two types of games, special games and regular games, that proceed in parallel. When these two games are played, the game proceeds in one of the game states which is a combination of either a low-probability game state or a high-probability game state and either a non-time-saving game state or a time-saving game state.

[0076] Details of each game state will be described later, but the low-probability game state is a game state in which the probability of acquiring the right to perform a major prize game in which the first major prize slot 126 and the second major prize slot 128 are opened is set to be low, and the high-probability game state is a game state in which the probability of acquiring the right to perform a major prize game is set to be high.

[0077] Furthermore, the non-time-saving game state is a game state in which the movable piece 122b is less likely to open and game balls are less likely to enter the second start opening 122, while the time-saving game state is a game state in which the movable piece 122b is more likely to open than in the non-time-saving game state and game balls are more likely to enter the second start opening 122. The initial state of the game machine 100 is set to the low-probability game state and the non-time-saving game state, and in this embodiment, this game state is referred to as the normal game state.

[0078] When a player operates the control 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 opening 120 or the second start opening 122, a lottery is held to determine whether or not the player is awarded a game prize (hereinafter referred to as the "Big Prize Lottery"). If the Big Prize Lottery results in a Big Win or a Small Win, the first Big Prize opening 126 and the second Big Prize opening 128 are opened, and a Big Prize game or Small Prize game is executed, allowing game balls to enter the first Big Prize opening 126 and the second Big Prize opening 128. Furthermore, the game state after the Big Prize game ends is set to one of the above game states. The Big Prize Lottery method will be explained below.

[0079] As will be explained in more detail later, when a game ball enters the first start port 120 or the second start port 122, various random values ​​related to the big prize lottery (jackpot determination random number, winning symbol random number, reach group determination random number, reach mode determination random number, and variation pattern random number) are acquired, and each of these random values ​​is stored in the special symbol reserve memory area of ​​the main RAM 300c. Hereafter, the various random numbers stored in the special symbol reserve memory area when a game ball enters the first start port 120 will be collectively referred to as Special 1 Reserve, and the various random numbers stored in the special symbol reserve memory area when a game ball enters the second start port 122 will be collectively referred to as Special 2 Reserve.

[0080] The main RAM 300c's special symbol hold memory area comprises a first special symbol hold memory area and a second special symbol hold memory area. The first and second special symbol hold memory areas each have four memory units (first to fourth memory units). When a game ball enters the first start port 120, special symbol 1 hold is stored sequentially starting from the first memory unit of the first special symbol hold memory area, and when a game ball enters the second start port 122, special symbol 2 hold is stored sequentially starting from the first memory unit of the second special symbol hold memory area.

[0081] For example, when a game ball enters the first start opening 120, if no hold is stored in any of the first to fourth memory units of the first special symbol hold memory area, special hold 1 is stored in the first memory unit. Also, for example, if special hold 1 is stored in the first to third memory units, and a game ball enters the first start opening 120, special hold 1 is stored in the fourth memory unit. Similarly, when a game ball enters the second start opening 122, special hold 2 is stored in the memory unit with the smallest number (ordinal number) among the first to fourth memory units of the second special symbol hold memory area, provided that special hold 2 is not already stored in that unit.

[0082] However, the number of special 1 reserves (X1) and special 2 reserves (X2) that can be stored in the first special reserve memory area and the second special reserve memory area are set to four, respectively. Therefore, for example, when a game ball enters the first start opening 120, if four special 1 reserves are already stored in the first special reserve memory area, no new special 1 reserves will be stored as a result of the game ball entering the first start opening 120. Similarly, when a game ball enters the second start opening 122, if four special 2 reserves are already stored in the second special reserve memory area, no new special 2 reserves will be stored as a result of the game ball entering the second start opening 122.

[0083] Figure 5 is a diagram illustrating the low-probability jackpot determination random number determination table according to this embodiment. When a game ball enters the first start port 120 or the second start port 122, one jackpot determination random number is obtained from the range of 0 to 65535. Then, when the jackpot lottery is started, that is, when the jackpot is determined, a jackpot determination random number determination table is selected according to the game state, and the jackpot lottery is performed using the selected jackpot determination random number determination table and the obtained jackpot determination random number.

[0084] In a low-probability game state, when initiating a major prize draw for Special 1 and Special 2 reserves, the low-probability jackpot determination random number table is referenced. In this embodiment, six setting values ​​with different degrees of advantage are provided, and a low-probability jackpot determination random number table is provided for each setting value. During gameplay, the setting value is set to one of the six levels, and the major prize draw is performed by referencing the low-probability jackpot determination random number table corresponding to the currently set setting value (registered setting value stored in the setting value buffer).

[0085] In a low-probability game state, when the setting value is set to 1 (registered setting value = 1), the big win lottery is conducted by referring to the low-probability big win determination random number table a shown in Figure 5(a). According to this low-probability big win determination random number table a, a big win is determined if the big win determination random number is between 10001 and 10218, a small win is determined if the big win determination random number is between 20001 and 21310, and a loss is determined if any other big win determination random number is used. Therefore, the probability of a big win in this case is approximately 1 / 300.6, and the probability of a small win is approximately 1 / 50.

[0086] In a low-probability game state, when the setting value is set to 2 (registered setting value = 2), the big win lottery is conducted by referring to the low-probability big win determination random number table b shown in Figure 5(b). According to this low-probability big win determination random number table b, a big win is determined if the big win determination random number is between 10001 and 10225, a small win is determined if the big win determination random number is between 20001 and 21310, and a loss is determined if any other big win determination random number is used. Therefore, the probability of a big win in this case is approximately 1 / 291.2, and the probability of a small win is approximately 1 / 50.

[0087] In a low-probability game state, when the setting value is set to 3 (registered setting value = 3), the big win lottery is conducted by referring to the low-probability big win determination random number table c shown in Figure 5(c). According to this low-probability big win determination random number table c, a big win is determined if the big win determination random number is between 10001 and 10232, a small win is determined if the big win determination random number is between 20001 and 21310, and a loss is determined if any other big win determination random number is used. Therefore, the probability of a big win in this case is approximately 1 / 282.4, and the probability of a small win is approximately 1 / 50.

[0088] In a low-probability game state, when the setting value is set to 4 (registered setting value = 4), the big win lottery is conducted by referring to the low-probability big win determination random number table d shown in Figure 5(d). According to this low-probability big win determination random number table d, a big win is determined if the big win determination random number is between 10001 and 10239, a small win is determined if the big win determination random number is between 20001 and 21310, and a loss is determined if any other big win determination random number is used. Therefore, the probability of a big win in this case is approximately 1 / 274.2, and the probability of a small win is approximately 1 / 50.

[0089] In a low-probability game state, if the setting value is set to 5 (registered setting value = 5), the big win lottery is conducted by referring to the low-probability big win determination random number table e shown in Figure 5(e). According to this low-probability big win determination random number table e, a big win is determined if the big win determination random number is between 10001 and 10246, a small win is determined if the big win determination random number is between 20001 and 21310, and a loss is determined if any other big win determination random number is used. Therefore, the probability of a big win in this case is approximately 1 / 266.4, and the probability of a small win is approximately 1 / 50.

[0090] In a low-probability game state, if the setting value is set to 6 (registered setting value = 6), the big win lottery is performed by referring to the low-probability big win determination random number table f shown in Figure 5(f). According to this low-probability big win determination random number table f, a big win is determined if the big win determination random number is between 10001 and 10253, a small win is determined if the big win determination random number is between 20001 and 21310, and a loss is determined if any other big win determination random number is used. Therefore, in this case, the probability of a big win is approximately 1 / 259.0, and the probability of a small win is approximately 1 / 50.

[0091] Figure 6 illustrates the high-probability state jackpot determination random number table according to this embodiment. When a jackpot lottery is initiated for Special 1 and Special 2 reserves in a high-probability game state, the high-probability state jackpot determination random number table is referenced. The high-probability state jackpot determination random number table is also provided for each setting value, similar to the low-probability state jackpot determination random number table.

[0092] When in a high-probability game state and the setting value is set to 1 (registered setting value = 1), the big win lottery is conducted by referring to the high-probability big win determination random number table a shown in Figure 6(a). According to this high-probability big win determination random number table a, a big win is determined if the big win determination random number is between 10001 and 10620, a small win is determined if the big win determination random number is between 20001 and 21310, and a loss is determined if the big win determination random number is any other. Therefore, in this case, the probability of a big win is approximately 1 / 105.7, and the probability of a small win is approximately 1 / 50.

[0093] Similarly, in a high-probability game state, when the setting value is set to 2-6 (registered setting value = 2-6), the big win lottery is conducted by referring to the high-probability big win determination random number judgment tables b-f shown in Figures 6(b)-(f). According to these high-probability big win determination random number judgment tables b-f, a big win is determined when the big win determination random number is the value shown in the figure. Therefore, the big win probability for setting values ​​2-6 is approximately 1 / 102.4-1 / 91.0, and the small win probability is approximately 1 / 50.

[0094] As described above, the major prize draw is conducted according to the registered setting value. At this time, the probability of winning the jackpot differs depending on the registered setting value, and it is easier to win the jackpot when the registered setting value is larger than when it is smaller. Here, it is assumed that the probability of winning a minor prize does not change even if the registered setting value is different, but it is also possible to make the probability of winning a minor prize different for each registered setting value. Furthermore, minor prizes are not mandatory, and it is also possible for only a jackpot or a loss to be determined in the major prize draw.

[0095] Furthermore, while here it is assumed that the probability of winning a jackpot in both the low-probability and high-probability game states differs according to the registered setting value, it is also possible that only the probability of winning a jackpot in either the low-probability or high-probability game state differs according to the registered setting value.

[0096] Figure 7 illustrates the winning symbol random number determination table according to this embodiment. When a game ball enters the first start port 120 or the second start port 122, one winning symbol random number is obtained from the range of 0 to 99. Then, when the above-mentioned major prize lottery determines whether the result is a "big win" or a "minor win", the type of special symbol is determined by the obtained winning symbol random number and the winning symbol random number determination table. At this time, if a "big win" is achieved by special 1 reserve, special 1 winning symbol random number determination table a is selected, as shown in Figure 7(a), and if a "minor win" is achieved by special 1 reserve, special 1 winning symbol random number determination table b is selected, as shown in Figure 7(b). Furthermore, if a "big win" is achieved by special 2 reserve, special 2 winning symbol random number determination table a is selected, as shown in Figure 7(c), and if a "minor win" is achieved by special 2 reserve, special 2 winning symbol random number determination table b is selected, as shown in Figure 7(d). In the following, the special symbols determined by the winning symbol random number, that is, the special symbols determined when a jackpot is determined, will be called jackpot symbols, the special symbols determined when a minor win is determined will be called minor win symbols, and the special symbols determined when a losing result is determined will be called losing symbols.

[0097] According to the special symbol random number determination table a for special 1 shown in Figure 7(a) and the special symbol random number determination table a for special 2 shown in Figure 7(c), the type of special symbol (jackpot symbol) is determined according to the acquired value of the winning symbol random number, as shown in the figure. Furthermore, according to the special symbol random number determination table b for special 1 shown in Figure 7(b) and the special symbol random number determination table b for special 2 shown in Figure 7(d), regardless of the acquired value of the winning symbol random number, the type of special symbol (minor win symbol) is determined to be special symbol a, as shown in the figure.

[0098] On the other hand, if the result of the major prize lottery is "miss," and that result is derived by Special 1 Reserve, then Special Symbol X is determined as the losing symbol without conducting a lottery. Also, if the result of the major prize lottery is "miss," and that result is derived by Special 2 Reserve, then Special Symbol Y is determined as the losing symbol without conducting a lottery.

[0099] In other words, the winning symbol random number determination table is only referenced when the major role lottery result is "Big Win" or "Minor Win," and is not referenced when the major role lottery result is "Loss." Here, it is assumed that the same big win symbol is determined in the special 1 winning symbol random number determination table and the special 2 winning symbol random number determination table, respectively. However, it is also possible to determine different big win symbols in the two tables, or to determine the type of special symbol (big win symbol) by referring to the winning symbol random number determination table 1, regardless of the type of hold.

[0100] In this example, the selection ratio of the jackpot symbol and the minor prize symbol is the same for all settings, but either the jackpot symbol or the minor prize symbol, or both, may be different for each setting.

[0101] Figure 8 is a diagram illustrating the reach group determination random number judgment table according to this embodiment. Multiple reach group determination random number judgment tables are provided, and a pre-set table is selected according to the type of hold, the number of holds, the game state, the fluctuation state associated with the game state, etc. When a game ball enters the first start opening 120 or the second start opening 122, one reach group determination random number is obtained from the range of 0 to 10006. As described above, when the big win lottery result is derived, a process is performed to determine the fluctuation performance pattern that notifies the big win lottery result. In this embodiment, when the big win lottery result is "miss", the group type is first determined by the reach group determination random number and the reach group determination random number judgment table in determining the fluctuation performance pattern. The fluctuation state is a concept set separately from the game state, which specifies which table is referred to to determine the fluctuation performance pattern.

[0102] For example, when the game state is set to a non-time-saving game state, if a "miss" result is derived from the special 1 reserve, and the number of special 1 reserves (hereinafter simply referred to as "reserve count") when the big win lottery is performed is 0, then as shown in Figure 8(a), the reach group determination random number judgment table 1 is selected. Similarly, when the game state is set to a normal game state, if a "miss" result is derived from the special 1 reserve, and the number of reserves when the big win lottery is performed is 1 to 2, then as shown in Figure 8(b), the reach group determination random number judgment table 2 is selected, and if the number of reserves is 3, then as shown in Figure 8(c), the reach group determination random number judgment table 3 is selected. Note that in Figure 8, the group x listed in the group type column represents an arbitrary group number. Therefore, various group numbers are determined as the group type depending on the acquired reach group determination random number and the type of reach group determination random number judgment table being referenced.

[0103] In this explanation, we have described the random number determination table for determining the reach group, which is referenced when a "miss" major role lottery result is derived based on the special 1 reserve during non-time-saving gameplay. However, the main ROM 300b also stores many other random number determination tables for determining the reach group.

[0104] Furthermore, if the result of the major role lottery is "Big Win" or "Minor Win," the group type is not determined when deciding the variation animation pattern. In other words, the random number judgment table for determining the reach group is only referenced when the result of the major role lottery is "Miss," and is not referenced when the result of the major role lottery is "Big Win" or "Minor Win."

[0105] Figure 9 illustrates the random number determination table for determining the reach mode according to this embodiment. This random number determination table for determining the reach mode is broadly divided into three types: a random number determination table for determining the reach mode when the big role lottery result is a "miss," a random number determination table for determining the reach mode when the big role lottery result is a "jackpot," and a random number determination table for determining the reach mode when the big role lottery result is a "minor win." The random number determination table for determining the reach mode when a miss is provided for each group type determined as described above, while the random number determination table for determining the reach mode when a jackpot and the random number determination table for determining the reach mode when a minor win are provided for each type of hold.

[0106] Furthermore, each reach mode determination random number judgment table is also provided for each game state and symbol type. Here, an example of the reach mode determination random number judgment table for group x when missing, which is referenced in a predetermined game state and symbol type, is shown in Figure 9(a), an example of the reach mode determination random number judgment table for special 1 when hitting a jackpot is shown in Figure 9(b), an example of the reach mode determination random number judgment table for special 2 when hitting a jackpot is shown in Figure 9(c), an example of the reach mode determination random number judgment table for special 1 when hitting a minor jackpot is shown in Figure 9(d), and an example of the reach mode determination random number judgment table for special 2 when hitting a minor jackpot is shown in Figure 9(e).

[0107] When a game ball enters the first start port 120 or the second start port 122, a random number for determining the reach mode is obtained from within the range of 0 to 250. If the result of the above-mentioned big win lottery is "miss", as shown in Figure 9(a), a random number determination table for determining the reach mode in the event of a miss, corresponding to the group type determined by the above-mentioned lottery for the group type, is selected, and the variable mode number is determined based on the selected random number determination table for determining the reach mode in the event of a miss and the random number for determining the reach mode. If the result of the above-mentioned big win lottery is "jackpot", as shown in Figures 9(b) and (c), a random number determination table for determining the reach mode in the event of a jackpot, corresponding to the read-out hold type, is selected, and the variable mode number is determined based on the selected random number determination table for determining the reach mode in the event of a jackpot and the random number for determining the reach mode.

[0108] Furthermore, if the result of the above major role lottery is a "minor win," as shown in Figures 9(d) and (e), a random number determination table for determining the reach mode during a minor win corresponding to the read-out hold type is selected, and the variable mode number is determined based on the selected random number determination table for determining the reach mode during a minor win and the reach mode determination random number.

[0109] Furthermore, in each reach mode determination random number judgment table, the reach mode determination random number is associated with the variation mode number and the variation pattern random number judgment table described later, and the variation pattern random number judgment table is determined at the same time as the variation mode number is determined. Note that in Figure 9, table x written in the column for the variation pattern random number judgment table indicates an arbitrary table number. Therefore, the variation mode number and the table number of the variation pattern random number judgment table are determined according to the acquired reach group determination random number and the type of reach mode determination random number judgment table to be referenced. In addition, in this embodiment, the variation mode number and the variation pattern number described later are set in hexadecimal. In the following, "H" is used to indicate hexadecimal numbers, but "○○H" written in Figures 9 to 11 indicates an arbitrary value shown in hexadecimal.

[0110] As described above, if the result of the major role lottery 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 Figure 8. Then, according to the determined group type and game state, the variation mode number and variation pattern random number judgment table are determined by the miss reach mode determination random number judgment table and reach mode determination random number shown in Figure 9(a).

[0111] On the other hand, if the result of the major role lottery is a "big win" or a "minor win," the random number determination table for determining the reach mode at the time of the big win, shown in Figure 9, is referenced to determine the random number for determining the reach mode, which corresponds to the determined big win symbol or minor win symbol (type of special symbol), the game state at the time of the big win or minor win, and the variable mode number and variable pattern random number determination table are determined using the random number for determining the reach mode.

[0112] Figure 10 illustrates the variable pattern random number determination table according to this embodiment. Here, we show the variable pattern random number determination table x with a predetermined table number x, but many other variable pattern random number determination tables are also provided for each table number.

[0113] When a game ball enters the first starting port 120 or the second starting port 122, one random variation pattern number is obtained from the range of 0 to 238. Then, based on the random variation pattern number determination table determined simultaneously with the above-mentioned variation mode number and the obtained random variation pattern number, the variation pattern number is determined as shown in the figure.

[0114] In this way, when the big prize lottery is held, the variation mode number and variation pattern number are determined according to the big prize lottery result, the determined symbol type, the game state, the number of reserved symbols, the type of reserved symbols, etc. These variation mode numbers and variation pattern numbers identify the variation performance pattern, and each of them is associated with the manner and duration of the variation performance.

[0115] Figure 11 is a diagram illustrating the variation time determination table according to this embodiment. As described above, once the variation mode number is determined, variation time 1 is determined according to the variation time 1 determination table shown in Figure 11(a). According to this variation time 1 determination table, 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.

[0116] Furthermore, as described above, once the variation pattern number is determined, variation time 2 is determined according to the variation time 2 determination table shown in Figure 11(b). According to this variation time 2 determination table, 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 sum of variation times 1 and 2 determined in this way becomes the time of the variation animation that announces the result of the big prize lottery, i.e., the variation time.

[0117] Once the variation mode number is determined as described above, a variation mode command corresponding to the determined variation mode number is transmitted to the sub-control board 330. Once the variation pattern number is determined, a variation pattern command corresponding to the determined variation pattern number is transmitted to the sub-control board 330. The sub-control board 330 primarily determines the first half of the variation performance based on the received variation mode command, and primarily determines the second half of the variation performance based on the received variation pattern command. Details of this will be described later. In the following, the variation mode number and variation pattern number may be collectively referred to as variation information, and the variation mode command and variation pattern command may be collectively referred to as variation commands.

[0118] Figure 12 is a diagram illustrating the special electric mechanism operation ramset table according to this embodiment. This special electric mechanism operation ramset table stores various data for controlling big win games or small win games. During big win games and small win games, the first big prize slot solenoid 126c and the second big prize slot solenoid 128c are energized by referring to this special electric mechanism operation ramset table. In reality, multiple special electric mechanism operation ramset tables are provided for each type of special symbol (big win symbol and small win symbol), and the corresponding table is set at the start of a big win game or small win game according to the determined type of special symbol. However, for the sake of explanation, all the control data for special symbols is shown in one table here.

[0119] When a special symbol A, B, or C, which is a jackpot symbol, or a special symbol a, which is a minor jackpot symbol, is determined, as shown in Figure 12, an opening and closing process is executed to control the opening and closing of the first jackpot 126 and the second jackpot 128 in a predetermined opening and closing pattern by referring to the special electric mechanism operation ramset table. A jackpot game consists of multiple rounds in which the second jackpot 128 is opened and closed a predetermined number of times, while a minor jackpot game consists of only one round in which the first jackpot 126 is opened and closed a predetermined number of times.

[0120] According to this special electric mechanism operation ramset table, the opening time (waiting time until the first round of gameplay begins), the maximum number of special electric mechanism operations (number of rounds of gameplay performed during one major win or minor win game), the number of openings for the main prize slots (the first and second main prize slots 126 and 128 that are opened in each round of gameplay), the number of special electric mechanism opening / closing switches (the number of times the first and second main prize slots 126 and 128 are opened during one round of gameplay), and the solenoid energizing time (the solenoids 126c and 2nd main prize slot solenoids for each number of times the first and second main prize slots 126 and 128 are opened). The energizing time of the lenoid 128c (i.e., the time the first and second large prize slots 126 and 128 are open for one round), the specified number (the maximum number of prizes that can be won into the first and second large prize slots 126 and 128 in one round of play), the effective closing time of the large prize slots (the time the first and second large prize slots 126 and 128 are closed between rounds of play, i.e., the interval time between rounds), and the ending time (the waiting time from the end of the last round of play until the normal special game resumes) are pre-stored as control data for the big prize game, for each type of big prize symbol and small prize symbol, as shown in the figure.

[0121] In this embodiment, when special symbols A and B, which are the winning symbols, are determined, a grand prize game consisting of 5 rounds is executed in both cases, and when special symbol C is determined, a grand prize game consisting of 15 rounds is executed. Each round ends when a predetermined number (8 balls) of game balls enter the second large prize slot 128, or when a predetermined time (in this case, 29.0 seconds) has elapsed since the second large prize slot 128 was opened.

[0122] Furthermore, if the special symbol a, which is a minor win symbol, is determined, a minor win game consisting of one round of gameplay is executed. In the minor win game executed when special symbol a is determined, the first major prize slot 126 is opened for 0.9 seconds twice during the first round of gameplay, with a predetermined pause in between.

[0123] Figure 13 illustrates a game state setting table for setting the game state after the completion of a major prize game according to this embodiment. In this embodiment, when a major prize game is played, the game state after the completion of the major prize game is set according to the type of special symbol determined at the time of winning the jackpot.

[0124] According to this game state setting table, if the winning symbol is special symbol A, the game state is set to a low probability game state after the big win game ends. On the other hand, if the winning symbol is special symbol B or C, the game state is set to a high probability game state after the big win game ends, and the number of times the high probability game state continues (hereinafter referred to as "high probability count") is set to 10,000. This means that the high probability game state will continue until the big win lottery result is confirmed 10,000 times. However, the high probability count mentioned above represents the maximum number of times that can continue in a high probability game state, and if a big win is achieved before reaching the above number of consecutive wins, the high probability count will be set again. Therefore, if the game state is set to a high probability game state after the big win game ends, and no big win lottery result is obtained in that high probability game state, and a losing lottery result is obtained 10,000 times, the game state will be changed to a low probability game state.

[0125] Furthermore, after a major win is completed, the game is set to a time-saving game state, and the number of times the time-saving game state will continue (hereinafter referred to as "time-saving rounds") is set. At this time, if the winning symbol is special symbol A, the time-saving rounds are set to 100, and if it is special symbol B or C, the time-saving rounds are set to 10,000. This means that the time-saving game state will continue until the major win lottery result is confirmed to be 100 or 10,000 times. However, the above-mentioned time-saving rounds represent the maximum number of consecutive rounds in one time-saving game state, and if a jackpot is won before reaching the above number of consecutive rounds, the time-saving rounds will be set again.

[0126] Figure 14 is a diagram illustrating the random number determination table for determining a winning combination according to this embodiment. When a game ball flowing down the game area 116 passes through the gate 124 (the game ball enters the regular symbol opening 125), a determination process for the corresponding regular symbol (hereinafter referred to as "regular symbol lottery") is performed to determine whether or not to energize the movable piece 122b of the second start opening 122.

[0127] As will be explained in more detail later, when a game ball passes through gate 124 (enters the normal ball operation opening 125), one winning random number is obtained from the range of 0 to 99, and up to four of these random numbers are stored in the normal ball reserve memory area of ​​the main RAM 300c. In other words, the normal ball reserve memory area has four memory units for saving winning random numbers. Therefore, if a game ball passes through gate 124 (enters the normal ball operation opening 125) while all four memory units of the normal ball reserve memory area have already stored winning random numbers, no new winning random number will be stored based on the passage of that game ball. Hereafter, a winning random number stored in the normal ball reserve memory area after a game ball passes through gate 124 (enters the normal ball operation opening 125) will be referred to as a normal ball reserve.

[0128] When a regular symbol draw is initiated in a non-time-saving game state, the random number determination table for non-time-saving game states is referenced, as shown in Figure 14(a). According to this random number determination table for non-time-saving game states, if the random number for determining the win is 0, a winning symbol is determined as the type of regular symbol, and if the random number for determining the win is between 1 and 99, a losing symbol is determined as the type of regular symbol. Therefore, the probability of a winning symbol being determined in a non-time-saving game state, i.e., the probability of winning, is 1 / 100. As will be explained in more detail later, if a winning symbol is determined in this regular symbol draw, the second start port 122 is controlled to be in an open state, and if a losing symbol is determined, the second start port 122 is kept in a closed state.

[0129] Furthermore, when starting a regular symbol draw in the shortened play state, the random number determination table for the shortened play state is referenced, as shown in Figure 14(b). According to this random number determination table for the shortened play state, if the random number for determining the win is between 0 and 98, a winning symbol is determined as the type of regular symbol, and if the random number for determining the win is 99, a losing symbol is determined as the type of regular symbol. Therefore, the probability of a winning symbol being determined in the shortened play state, i.e., the probability of winning, is 99 / 100.

[0130] Figure 15(a) is a diagram illustrating the normal symbol variation time data table according to this embodiment, and Figure 15(b) is a diagram illustrating the opening / closing control pattern table according to this embodiment. As described above, when a normal symbol lottery is performed, the variation time of the normal symbols is determined. The normal symbol variation time data table is referenced when determining the variation time of a normal symbol when a winning symbol or a losing symbol is determined by the normal symbol lottery. According to this normal symbol variation time data table, if the game state is set to a non-time-saving game state, the variation time is determined to be 10 seconds, and if the game state is set to a time-saving game state, the variation time is determined to be 1 second. Once the variation time is determined in this way, the normal symbol indicator 168 is displayed (flashed) for the determined time. When a winning symbol is determined, the normal symbol indicator 168 lights up, and when a losing symbol is determined, the normal symbol indicator 168 turns off.

[0131] Then, when the winning symbol is determined by the regular symbol lottery and the regular symbol indicator 168 lights up, the movable piece 122b of the second start port 122 is powered on by referring to the opening / closing control pattern table, as shown in Figure 15(b). In reality, an opening / closing control pattern table is provided for each game state, and the corresponding table is set when the regular electric mechanism solenoid 122c is powered on, depending on the game state when the regular symbol is determined. However, for the sake of explanation, here, the control data corresponding to each game state is shown in a single table.

[0132] Once the winning symbol is determined, the second start port 122 is opened and closed by referring to the opening and closing control pattern table, as shown in Figure 15(b). According to this opening / closing control pattern table, the following are stored in advance as control data for the second start port 122 for each game state, as shown in the figure: time before normal opening (waiting time until the opening of the second start port 122 begins), maximum number of normal electric mechanism opening / closing switches (number of times the second start port 122 is opened), solenoid energizing time (energizing time of the normal electric mechanism 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), specified number (maximum number of possible winnings into the second start port 122 during the entire opening of the second start port 122), normal closing effective time (closing time between each opening of the second start port 122, i.e., pause time), normal effective state time (waiting time from the end of the last opening of the second start port 122), and normal end wait time (waiting time after the normal effective state time has elapsed until the display of the normal symbols, described later, resumes).

[0133] Thus, the non-time-saving game state and the time-saving game state are each associated with opening and closing control conditions for opening and closing the second start opening 122 as game progression conditions. In the time-saving game state, it is easier for game balls to enter the second start opening 122 than in the non-time-saving game state. In other words, in the time-saving game state, as long as game balls pass through the gate 124 (game balls enter the normal opening 125), normal draws are performed one after another, and the second start opening 122 is frequently open, allowing players to perform big draws while reducing the consumption of game balls.

[0134] The opening and closing conditions for the second start port 122 are defined by three elements: the probability of winning with a normal symbol, the duration of the normal symbol's variation display, and the duration of the second start port 122's opening. In this embodiment, two of these elements are set to be more favorable in the time-saving game state than in the non-time-saving game state, so that it is easier for game balls to enter the second start port 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 favorable in the time-saving game state than in the non-time-saving game state. In any case, the goal is to ensure that the time-saving game state is more favorable in at least one element compared to the non-time-saving game state, so that overall, it is easier for game balls to enter the second start port 122 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 should be controlled to open and close according to the first condition, and when the game state is set to a time-saving game state, the movable piece 122b should be controlled to open and close according to the second condition, which is more likely to be in the open state than the first condition.

[0135] Furthermore, in this embodiment, a general-purpose opening 125 is provided in the second game area 116b, and almost all of the game balls that flow down to the bottom of the second game area 116b enter the general-purpose opening 125. When a game ball enters the general-purpose opening 125, one prize ball is dispensed. Therefore, even if a game ball is launched into the second game area 116b in a non-time-saving game state, the number of game balls hardly decreases. However, the general-purpose opening 125 is not an essential configuration, and the board configuration is merely an example. Therefore, a configuration in which the number of game balls decreases when a game ball is launched into the second game area 116b in a non-time-saving game state is also acceptable.

[0136] Next, the main processing of the main control board 300 as the game progresses in the gaming machine 100 according to this embodiment will be described.

[0137] Figure 16 is a diagram illustrating the gaming machine status flag according to this embodiment. In the main control board 300, whether or not the game is in a state where it can proceed is managed by the gaming machine status flag. The gaming machine status flag is set to one of six flag values ​​from 00H to 05H. A flag value of 00H indicates that the game is playable. When the gaming machine status flag is 00H, the game is controlled to proceed, and when the gaming machine status flag is anything other than 00H, the game is stopped.

[0138] A flag value of 01H for the game machine status flag indicates a setting change state. When the game machine status flag is 01H, it becomes possible to change the registered setting value. A flag value of 02H for the game machine status flag indicates a setting confirmation state. When the game machine status flag is 02H, it becomes possible to confirm the registered setting value, for example, by displaying it on the performance display monitor 184. A flag value of 03H for the game machine status flag indicates a setting abnormality state. When the game machine status flag is 03H, the game is stopped because the registered setting value is abnormal. A flag value of 04H for the game machine status flag indicates an RWM (read write memory) abnormality state. When the game machine status flag is 04H, the game is stopped. A flag value of 05H for the game machine status flag indicates a checksum abnormality state. When the game machine status flag is 05H, the game is stopped. When the power is turned on, the game machine status flag is set to one of the flag values, and processing is performed according to the game machine status flag.

[0139] (CPU initialization process of the main control board 300) Figure 17 is a first flowchart illustrating the CPU initialization process in the main control board 300 according to this embodiment, and Figure 18 is a second flowchart illustrating the CPU initialization process in the main control board 300 according to this embodiment.

[0140] 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).

[0141] (Step S100-1) When powered on, the main CPU 300a reads the boot program from the main ROM 300b as part of the initial setup process, and also performs the necessary configuration processes to execute various other operations.

[0142] (Step S100-3) The main CPU 300a sets the wait processing time in the timer counter.

[0143] (Step S100-5) The main CPU 300a determines whether it has detected a power failure warning signal. The main control board 300 is equipped with a power failure detection circuit, and when the power supply voltage falls below a predetermined value, the power failure detection circuit outputs a power failure warning signal. If a power failure warning signal is detected, the process proceeds to step S100-3 above; if a power failure warning signal is not detected, the process proceeds to step S100-7.

[0144] (Step S100-7) The main CPU 300a determines whether the wait time set in step S100-3 has elapsed. If it determines that the wait time has elapsed, it proceeds to step S100-9; if it determines that the wait time has not elapsed, it proceeds to step S100-5.

[0145] (Step S100-9) The main CPU 300a performs the necessary processing to allow access to the main RAM 300c.

[0146] (Step S100-11) The main CPU 300a loads the flag value of the gaming machine's state flag before the power was cut off into the D register.

[0147] (Step S100-13) The main CPU 300a calculates a checksum and determines whether the calculated checksum matches (is normal) the checksum stored at the time of power failure, and whether the backup flag is normal. If it is determined that both the backup flag and the checksum are normal, the process moves to step S100-15. If it is determined that either or both are not normal, the process moves to step S100-25.

[0148] (Step S100-15) The main CPU 300a sets the starting address of the main RAM 300c to an address that does not contain the setting value or the gaming machine status flag.

[0149] (Step S100-17) The main CPU 300a determines whether a RAM clear operation signal is being input from the RAM clear switch 182s (i.e., whether the RAM clear button is being pressed). If it determines that a RAM clear operation signal is being input, the process moves to step S100-31; if it determines that no RAM clear operation signal is being input, the process moves to step S100-19.

[0150] (Step S100-19) The main CPU 300a determines whether the flag value of the game machine status flag loaded in step S100-11 is 00H (playable state), whether the setting change switch 180s is ON, and whether the middle frame 104 is open. If it determines that all three conditions are met, the process moves to step S100-21; if it determines that even one of the three conditions is not met, the process moves to step S100-23.

[0151] (Step S100-21) The main CPU 300a sets the gaming machine status flag to 02H (settings confirmation state). In other words, when the middle frame 104 is open, the settings change switch 180s is on, and the RAM clear button is not pressed, and the power is turned on normally, the machine enters the settings confirmation state.

[0152] (Step S100-23) The main CPU 300a performs an initialization process to clear the area of ​​the main RAM 300c that is to be cleared when power is restored, which is the area from the starting address set in step S100-15 above, and then proceeds to step S100-49.

[0153] (Step S100-25) The main CPU 300a sets the D register to 05H (checksum error state).

[0154] (Step S100-27) The main CPU 300a performs out-of-bounds read / write checks, which involve checking and clearing read / write memory in unused areas.

[0155] (Step S100-29) The main CPU 300a sets the address containing the setting value and the gaming machine status flag to the starting address of the main RAM 300c that is to be cleared.

[0156] (Step S100-31) The main CPU 300a checks and clears the read / write memory in the area being used.

[0157] (Step S100-33) The main CPU 300a determines whether the read / write memory check in step S100-31 is normal. If it determines that it is normal, it proceeds to step S100-37; if it determines that it is not normal, it proceeds to step S100-35.

[0158] (Step S100-35) The main CPU 300a sets the D register to 04H (RWM abnormal state) and moves processing to step S100-45.

[0159] (Step S100-37) The main CPU 300a determines whether 02H (setting confirmation state) is set in the D register. If it determines that 02H is set, it proceeds to step S100-39; if it determines that 02H is not set, it proceeds to step S100-41.

[0160] (Step S100-39) The main CPU 300a sets the D register to 00H (ready to play).

[0161] (Step S100-41) The main CPU 300a determines whether the setting change conditions are met. If it determines that the setting change conditions are met, the process moves to step S100-43; if it determines that the setting change conditions are not met, the process moves to step S100-45. Here, the setting change conditions include at least the setting change switch 180s being ON, the middle frame 104 being open, and a RAM clear operation signal being input from the RAM clear switch 182s.

[0162] (Step S100-43) The main CPU 300a sets the D register to 01H (setting change state).

[0163] (Step S100-45) The main CPU 300a saves the value set in the D register to the game machine status flag.

[0164] (Step S100-47) The main CPU 300a performs an initialization process to clear the main RAM 300c that is targeted for clearing during RAM clearing, and then proceeds to step S100-49.

[0165] (Step S100-49) The main CPU 300a performs the process of sending a payout command (RAM clear specification command) to the payout control board 310 to inform it that the main RAM 300c has been cleared (storing the RAM clear specification command in the transmit buffer).

[0166] (Step S100-51) The main CPU 300a loads the gaming machine status flags.

[0167] (Step S100-53) The main CPU 300a determines whether the game machine status flag loaded in step S100-51 is 00H (playable state). If it determines that it is 00H, it proceeds to step S110; otherwise, it proceeds to step S100-55.

[0168] (Step S110) The main CPU 300a performs the subcommand set processing. This subcommand set processing will be explained later.

[0169] (Step S100-55) The main CPU 300a performs subcommand set processing to send predetermined commands to the sub-control board 330. Here, commands corresponding to the game machine status flags are set. For example, if the game machine status flag is 01H, the setting change status specification command is set, and if the game machine status flag is 02H, the setting confirmation status specification command is set. In this way, by sending commands corresponding to the game machine status flags to the sub-control board 330, the internal state of the main control board 300 can be determined by the sub-control board 330.

[0170] (Step S100-57) The main CPU 300a sets the timer interrupt period.

[0171] (Step S100-59) The main CPU 300a performs the process to disable interrupts.

[0172] (Step S100-61) The main CPU 300a updates the initial value update random number for the winning symbol random number. This initial value update random number is used to determine the initial and final values ​​of the winning symbol random number. In other words, when the winning symbol random number update process described later cycles from the initial value update random number for the winning symbol random number to the current initial value update random number - 1, the winning symbol random number is updated to the initial value update random number for the winning symbol random number at that time.

[0173] (Step S100-63) The main CPU 300a analyzes the received data (main command) from the dispensing control board 310 and performs various processes according to the received data.

[0174] (Step S100-65) The main CPU 300a performs processing to send subcommands stored in the transmit buffer to the sub-control board 330.

[0175] (Step S100-67) The main CPU 300a performs the processing necessary to enable interrupts.

[0176] (Step S100-69) The main CPU 300a updates the random numbers for determining the reach group, the random numbers for determining the reach mode, and the random numbers for determining the variation pattern, and then repeats the process from step S100-59 described above. In the following, the random numbers for determining the reach group, the random numbers for determining the reach mode, and the random numbers for determining the variation pattern will be collectively referred to as random numbers for variation effects.

[0177] Figure 19 is a flowchart illustrating the subcommand group set process (S110) in the main control board 300 according to this embodiment.

[0178] (Step S110-1) The main CPU 300a loads the flag values ​​of the gaming machine status flags.

[0179] (Step S110-3) The main CPU 300a performs subcommand set processing to send predetermined commands to the sub-control board 330. For example, if initialization processing was performed in step S100-47 above, a RAM clear command is set.

[0180] (Step S110-5) The main CPU 300a performs a machine command setting process, which involves setting a machine command indicating the machine type information of the gaming machine 100 into the transmission buffer.

[0187] (Step S110-19) The main CPU 300a determines whether the special game management phase is in a state of waiting for a special symbol change. If it determines that it is in a state of waiting for a special symbol change, it proceeds to step S110-21; if it determines that it is not in a state of waiting for a special symbol change, it terminates the subcommand group set process.

[0188] (Step S110-21) The main CPU 300a sets the customer waiting command in the send buffer and terminates the process of setting the subcommand group.

[0189] Next, the interrupt processing in the main control board 300 according to this embodiment will be described. Here, the power outage saving process (XINT interrupt processing) and the timer interrupt processing will be described.

[0190] (Power outage saving process for main control board 300 (XINT interrupt processing)) Figure 20 is a flowchart illustrating the power failure escape process (XINT interrupt processing) in the main control board 300 according to this embodiment. The main CPU 300a monitors the power failure detection circuit, and when the power supply voltage falls below a predetermined value, it interrupts the CPU initialization process to execute the power failure escape process.

[0191] (Step S300-1) When a power failure warning signal is received, the main CPU 300a saves its registers.

[0192] (Step S300-3) The main CPU 300a checks for a power failure warning signal.

[0193] (Step S300-5) The main CPU 300a determines whether it has detected a power failure warning signal. If it determines that it has detected a power failure warning signal, it proceeds to step S300-11; if it determines that it has not detected a power failure warning signal, it proceeds to step S300-7.

[0194] (Step S300-7) The main CPU 300a restores the registers.

[0195] (Step S300-9) The main CPU 300a performs the process to enable interrupts and then terminates the power-out save process.

[0196] (Step S300-11) The main CPU 300a executes an output port clear process, which stops the output from the output port.

[0197] (Step S300-13) The main CPU 300a performs a checksum setting process that calculates and saves the checksum.

[0198] (Step S300-15) The main CPU 300a performs the necessary RAM protection configuration process to prevent access to the main RAM 300c.

[0199] (Step S300-17) The main CPU 300a sets a predetermined number of power failure detection signals in the loop counter's counter value in order to set the power failure monitoring time.

[0200] (Step S300-19) The main CPU 300a checks for a power failure warning signal.

[0201] (Step S300-21) The main CPU 300a determines whether it has detected a power failure warning signal. If it determines that it has detected a power failure warning signal, it proceeds to step S300-17; if it determines that it has not detected a power failure warning signal, it proceeds to step S300-23.

[0202] (Step S300-23) The main CPU 300a decrements the value of the loop counter set in step S300-17 by 1.

[0203] (Step S300-25) The main CPU 300a determines whether the counter value of the loop counter is not zero. If it determines that the counter value is not zero, it proceeds to step S300-19; if it determines that the counter value is zero, it proceeds to the CPU initialization process described above (step S100).

[0204] If a power outage actually occurs, the operation of the gaming machine 100 will stop while steps S300-17 to S300-25 are looping.

[0205] (Timer interrupt processing on the main control board 300) Figure 21 is a flowchart illustrating the timer interrupt processing in the main control board 300 according to this embodiment. The main control board 300 is provided with a reset clock pulse generation circuit that generates a clock pulse at predetermined intervals (4 milliseconds in this embodiment, hereinafter referred to as "4ms"). When a clock pulse is generated by the reset clock pulse generation circuit, the CPU initialization process (step S100) is interrupted and the following timer interrupt processing is executed.

[0206] (Step S400-1) The main CPU 300a saves the registers.

[0207] (Step S400-3) The main CPU 300a performs the processing necessary to enable interrupts.

[0208] (Step S400-5) The main CPU 300a outputs common data set in the common output buffer to the output port and performs dynamic port output processing to control the illumination of the first special symbol indicator 160, the second special symbol indicator 162, the first special symbol hold indicator 164, the second special symbol hold indicator 166, the normal symbol indicator 168, the normal symbol hold indicator 170, the right-hand hit notification indicator 172, and the performance display monitor 184.

[0209] (Step S400-7) The main CPU 300a reads various input port information and performs port input processing to accurately obtain the latest switch status.

[0210] (Step S400-9) The main CPU 300a loads the flag values ​​of the gaming machine status flags.

[0211] (Step S400-11) The main CPU 300a determines whether the flag value loaded in step S400-9 is 00H (playable state). If it determines that it is 00H, it proceeds to step S400-15; otherwise, it proceeds to step S400-13.

[0212] (Step S400-13) The main CPU 300a determines whether the flag value loaded in step S400-9 is 03H (setting abnormal state) or higher. If it determines that it is 03H or higher, it proceeds to step S400-27; if it determines that it is not 03H or higher, it proceeds to step S450.

[0213] (Step S450) The main CPU 300a executes setting-related processing and transfers the processing to step S400-27. The setting-related processing will be described later.

[0214] (Step S400-15) The main CPU 300a performs timer update processing to update various timer counters. Here, unless otherwise specified, the various timer counters are decremented each time the timer interrupt processing of the main control board 300 occurs, and the decrement stops when it reaches 0.

[0215] (Step S400-17) The main CPU 300a executes update processing of the initial value update random number for the winning symbol random number, similar to step S100-61 above.

[0216] (Step S400-19) The main CPU 300a performs processing to update the winning symbol random number. Specifically, the random number counter is incremented by 1 for update. If the result of the addition exceeds the maximum value of the random number range, the random number counter is reset to 0. When the random number counter makes one full 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.

[0217] Although detailed description is omitted, in this embodiment, the big win determination random number and the win determination random number use hardware random numbers updated by the hardware random number generation unit built in the main control board 300. The hardware random number generation unit updates both the big win determination random number and the win determination random number according to a certain rule, automatically changes the random number sequence every time the random number sequence makes one full cycle, and changes the start value every time the system is reset.

[0218] (Step S500) The main CPU 300a executes a switch management process for determining whether there is an input signal from the first start port detection switch 120s, the second start port detection switch 122s, the gate detection switch 124s, the general drawing operation port detection switch 125s, the first major winning port detection switch 126s, and the second major winning port detection switch 128s. The details of this switch management process will be described later.

[0219] (Step S600) The main CPU 300a executes a special game management process for controlling the progress of the above special game. The details of this special game management process will be described later.

[0220] (Step S700) The main CPU 300a executes a normal game management process for controlling the progress of the above normal game. The details of this normal game management process will be described later.

[0221] (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. When it is determined that an error has occurred, the main CPU 300a sets an error designation command corresponding to the type of error.

[0222] (Step S400-23) The main CPU 300a checks the general winning port detection switch 118s, the first start port detection switch 120s, the second start port detection switch 122s, the first major winning port detection switch 126s, and the second major winning port detection switch 128s, and executes a winning port switch process for adding a counter for prize ball control and the like corresponding thereto.

[0223] (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 prize ball control set in the above step S400-23.

[0224] (Step S400-27) The main CPU 300a executes external information management processing to set output data for external information to be output externally from the game information output terminal board 312.

[0225] (Step S400-29) The main CPU 300a executes LED display setting processing, which sets common data for controlling the lighting of various indicators (LEDs) such as the first special symbol indicator 160, the second special symbol indicator 162, the first special symbol hold indicator 164, the second special symbol hold indicator 166, the normal symbol indicator 168, the normal symbol hold indicator 170, and the right-hand shooting notification indicator 172 into the common output buffer.

[0226] (Step S400-31) The main CPU 300a performs solenoid output image synthesis processing to synthesize the solenoid output images of the ordinary electric mechanism solenoid 122c, the first large prize slot solenoid 126c, the second large prize slot solenoid 128c, and the movable member drive solenoid 142c, and stores them in the output port buffer.

[0227] (Step S400-33) The main CPU 300a performs port output processing to output the values ​​of the common output buffer stored in each output port buffer to the output port.

[0228] (Step S400-35) The main CPU 300a performs the process to disable interrupts.

[0229] (Step S400-37) The main CPU 300a uses the unused area of ​​the main RAM 300c to perform processing to calculate the base ratio to be displayed on the performance display monitor 184, and executes performance display monitor control processing to set the calculated base ratio as common data to be displayed on the performance display monitor 184 in the common output buffer. In the performance display monitor control processing, the base ratio is calculated at predetermined intervals. The performance display monitor 184 may switch between displaying the base ratio for the current period and the base ratio for previous periods at predetermined intervals. In addition, the base ratio displayed on the performance display monitor 184 may be switched according to predetermined operations. Furthermore, if the game machine status flag is 01H or 02H, the main CPU 300a displays the registered setting value set in the setting value buffer on the performance display monitor 184.

[0230] (Step S400-39) The main CPU 300a restores its registers and terminates the timer interrupt processing.

[0231] Figure 22 is a flowchart illustrating the above-mentioned setting-related processing (S450) according to this embodiment.

[0232] (Step S450-1) The main CPU 300a determines whether the flag value of the gaming machine status flag is 01H (settings changed state). If it determines that the value is 01H, it proceeds to step S450-3; if it determines that the value is not 01H, it proceeds to step S450-15.

[0233] (Step S450-3) The main CPU 300a loads the registered setting values ​​stored in the setting value buffer into a designated processing area.

[0234] (Step S450-5) The main CPU 300a determines whether the RAM clear switch 182s is on (i.e., whether the RAM clear operation signal is input). As a result, if it is determined that the RAM clear switch 182s is on, the process proceeds to step S450-7; if it is determined that the RAM clear switch 182s is not on, the process proceeds to step S450-9.

[0235] (Step S450-7) The main CPU 300a adds 1 to the set value of the processing area.

[0236] (Step S450-9) The main CPU 300a determines whether the set value of the processing area is within the range of 1 to 6. As a result, if it is determined that the set value is within the range of 1 to 6, the process proceeds to step S450-13; if it is determined that the set value is not within the range of 1 to 6, the process proceeds to step S450-11.

[0237] (Step S450-11) The main CPU 300a sets the set value of the processing area to 1.

[0238] (Step S450-13) The main CPU 300a sets the set value of the processing area to the set value buffer.

[0239] (Step S450-15) The main CPU 300a determines whether the setting change switch 180s is on. As a result, if it is determined that the setting change switch 180s is on, the setting-related process ends; if it is determined that the setting change switch 180s is not on, the process proceeds to step S450-17.

[0240] (Step S450-17) The main CPU 300a sets a setting-related end designation command indicating the end of the setting-related process to the transmission buffer.

[0241] (Step S110) The main CPU 300a executes the subcommand set processing shown in Figure 19. That is, when setting-related processing is executed, the following commands are sent to the sub-control board 330 upon completion: machine command, setting value specification command, special figure 1 hold specification command, special figure 2 hold specification command, count command, variation pattern selection state specification command, special figure phase specification command, and customer waiting specification command.

[0242] (Step S450-19) The main CPU 300a sets the gaming machine status flag to 00H (playable state) and terminates the processing related to that setting.

[0243] As described above, according to this embodiment, when the power is turned on normally with the middle frame 104 open, the setting change switch 180s turned on, and the RAM clear button pressed, the game machine state flag is set to 01H (setting change state) during the CPU initialization process (Figure 17). After that, the timer interrupt process is executed, but because the game machine state flag is set to 01H (setting change state), all processes related to the progress of the game (steps S400-15 to S400-25 in Figure 21) are stopped and setting-related processes are executed.

[0244] The setting-related processing is executed repeatedly while the setting change switch 180s is ON, and during this setting-related processing, pressing the RAM clear button is accepted as a setting change operation for the registered setting value. In other words, during the setting change processing (S450-1 to S450-13) that accepts setting change operations, the registered setting value stored in the setting value buffer is switched to one of the multiple setting values ​​provided in response to the setting change operation.

[0245] Then, when the setting change switch 180s is switched off while the game machine status flag is set to 01H (settings changed state), the setting change process ends, and the game machine status flag is set to 00H (playable state). As a result, processing related to the progress of the game can be executed from the next timer interrupt process.

[0246] In this embodiment, during the setting-related processing, after the RAM clear button is pressed, i.e., after the acceptance of the setting change operation for the registered setting value is complete, a setting value specification command corresponding to the registered setting value is sent to the sub-control board 330 during the sub-command group set processing. On the other hand, while the setting change operation is being accepted, the setting value specification command is not sent to the sub-control board 330. In this way, by not sending the setting value specification command while the setting change operation is being accepted, and only sending the setting value specification command when the acceptance of the setting change operation is complete and the system transitions to a state where the game can proceed, the risk of the registered setting value being acquired illegally can be reduced.

[0247] Furthermore, in this embodiment, multiple flag values, including at least 01H (setting change state), are switched. When 01H (setting change state) is set in the game machine state flag, setting-related processing becomes executable, and the game progress is stopped. In this way, setting-related processing is not executed while the game is in progress, and no setting value specification command is sent while the game is in progress, thus reducing the risk of registered setting values ​​being illegally acquired.

[0248] Next, we will explain in detail the switch management process in step S500, the special game management process in step S600, and the normal game management process in step S700, which are part of the timer interrupt processing described above.

[0249] Figure 23 is a flowchart illustrating the switch management process (step S500) in the main control board 300 according to this embodiment.

[0250] (Step S500-1) The main CPU 300a determines whether the gate detection switch has been turned ON or the general-purpose opening detection switch has been turned ON, that is, whether a game ball has passed through the gate 124 and the detection signal from the gate detection switch 124s has been turned ON, or whether a game ball has entered the general-purpose opening 125 and the detection signal from the general-purpose opening detection switch 125s has been turned ON. If it is determined that the gate detection switch has been turned ON or the general-purpose opening detection switch has been turned ON, the process moves to step S510. If it is determined that the gate detection switch has not been turned ON or the general-purpose opening detection switch has not been turned ON, the process moves to step S500-3.

[0251] (Step S510) The main CPU 300a executes gate passage processing based on the passage of a game ball through gate 124 (the entry of a game ball into the normal operation opening 125). Details of this gate passage processing will be described later.

[0252] (Step S500-3) The main CPU 300a determines whether the first start port detection switch is ON, that is, whether a game ball has entered the first start port 120 and a detection signal has been input from the first start port detection switch 120s. If it determines that the first start port detection switch is ON, the process moves to step S520; if it determines that the first start port detection switch is NOT ON, the process moves to step S500-5.

[0253] (Step S520) The main CPU 300a executes the first start gate passage process based on the entry of a game ball into the first start gate 120. Details of this first start gate passage process will be described later.

[0254] (Step S500-5) The main CPU 300a determines whether the second start port detection switch is ON, that is, whether a game ball has entered the second start port 122 and a detection signal has been input from the second start port detection switch 122s. If it determines that the second start port detection switch is ON, the process moves to step S530; if it determines that the second start port detection switch is NOT ON, the process moves to step S500-7.

[0255] (Step S530) The main CPU 300a executes a second start gate passage process based on the entry of a game ball into the second start gate 122. Details of this second start gate passage process will be described later.

[0256] (Step S500-7) The main CPU 300a determines whether the big prize hole detection switch is ON, that is, whether a game ball has entered the first big prize hole 126 and the second big prize hole 128 and a detection signal has been input from the first big prize hole detection switch 126s and the second big prize hole detection switch 128s. If it is determined that the big prize hole detection switch is ON, the process moves to step S500-9; if it is determined that the big prize hole detection switch is NOT ON, the process moves to step S500-11.

[0257] (Step S500-9) The main CPU 300a determines whether a major prize game or a minor prize game is currently in progress, and whether the game balls were properly entered into the first major prize slot 126 and the second major prize slot 128. If it determines that a major prize game or a minor prize game is not in progress, it executes a predetermined fraud detection process. If it determines that a major prize game or a minor prize game is in progress and that the game balls were properly entered into the first major prize slot 126 and the second major prize slot 128, it increments the major prize slot ball count counter by 1 and sets the major prize slot entry designation command in the transmission buffer.

[0258] (Step S500-11) The main CPU 300a determines whether the general prize entry detection switch is ON, that is, whether a game ball has entered the general prize entry 118 and a detection signal has been input from the general prize entry detection switch 118s. If it determines that the general prize entry detection switch is ON, the process moves to step S500-13; if it determines that the general prize entry detection switch is NOT ON, the process moves to step S500-15.

[0259] (Step S500-13) The main CPU 300a sets the command for designating a general prize winner in the transmission buffer.

[0260] (Step S500-15) The main CPU 300a determines whether the out-of-bounds ball detection switch is turned ON, that is, whether a detection signal has been input from the out-of-bounds ball detection switch 130s. If it is determined that the out-of-bounds ball detection switch is turned ON, the process moves to step S500-17. If it is determined that the out-of-bounds ball detection switch is not turned ON, the switch management process is terminated.

[0261] (Step S500-17) The main CPU 300a sets the out-of-bounds ball detection command in the transmit buffer and terminates the switch management process.

[0262] Figure 24 is a flowchart illustrating the gate passage process (step S510) in the main control board 300 according to this embodiment.

[0263] (Step S510-1) The main CPU 300a loads the winning random number updated by the hardware random number generator.

[0264] (Step S510-3) The main CPU 300a determines whether the counter value of the normal symbol ball count counter is greater than or equal to the maximum value, that is, whether the counter value of the normal symbol ball count counter is 4 or greater. If it determines that the counter value of the normal symbol ball count counter is greater than or equal to the maximum value, the gate passage process is terminated. If it determines that the normal symbol ball count counter is not greater than or equal to the maximum value, the process moves to step S510-5.

[0265] (Step S510-5) The main CPU 300a updates the counter value of the normal symbol ball count counter to the current counter value plus "1".

[0266] (Step S510-7) The main CPU 300a determines which of the four memory units in the general data hold memory area will be used to save the acquired winning random number.

[0267] (Step S510-9) The main CPU 300a saves the random number used to determine the winner, obtained in step S510-1, to the target memory unit calculated in step S510-7.

[0268] (Step S510-11) The main CPU 300a sets a "normal diagram hold" command, which indicates the number of normal diagrams held in the normal diagram hold memory area, into the transmission buffer and terminates the gate passage process.

[0269] Figure 25 is a flowchart illustrating the first start port passage process (step S520) in the main control board 300 according to this embodiment.

[0270] (Step S520-1) The main CPU 300a sets the special symbol identification value to "00H". The special symbol identification value is used to identify whether the hold type is Special 1 hold or Special 2 hold. The special symbol identification value (00H) indicates Special 1 hold, and the special symbol identification value (01H) indicates Special 2 hold.

[0271] (Step S520-3) The main CPU 300a sets the address of the special symbol 1 reserved ball counter.

[0272] (Step S535) The main CPU 300a executes the special symbol random number acquisition process and then terminates the first start gate passage process. This special symbol random number acquisition process is executed using a module common to the second start gate passage process (step S530). Therefore, the details of the special symbol random number acquisition process will be explained after the explanation of the second start gate passage process.

[0273] Figure 26 is a flowchart illustrating the second start port passage process (step S530) in the main control board 300 according to this embodiment.

[0274] (Step S530-1) The main CPU 300a is set to "01H" as the special symbol identification value.

[0275] (Step S530-3) The main CPU 300a sets the address for the special symbol 2 reserved ball count counter.

[0276] (Step S535) The main CPU 300a executes the special symbol random number acquisition process, which will be described later.

[0277] (Step S530-5) The main CPU 300a loads the normal game management phase. As will be explained in more detail later, the normal game management phase indicates the stage of the normal game execution process, that is, the progress of the normal game, and is updated according to the stage of the normal game execution process.

[0278] (Step S530-7) The main CPU 300a determines whether the normal game management phase loaded in step S530-5 is "04H". The normal game management phase "04H" indicates that the normal electric prize entry opening control process is underway. In this normal electric prize entry opening control process, the normal electric prize solenoid 122c is energized and the movable piece 122b is controlled to the open state. Therefore, the CPU determines whether the second start opening 122 is in a state where it can be properly opened. If the CPU determines that the normal game management phase is not "04H", it terminates the second start opening passage process. If the CPU determines that the normal game management phase is "04H", it proceeds to step S530-9.

[0279] (Step S530-9) The main CPU 300a updates the counter value of the normal electric prize ball entry counter to the current counter value plus "1", and then terminates the process of passing through the second start gate.

[0280] Figure 27 is a flowchart illustrating the special symbol random number acquisition process (step S535) in the main control board 300 according to this embodiment. This special symbol random number acquisition process is performed using a common module in the first start gate passage process (step S520) and the second start gate passage process (step S530) described above.

[0281] (Step S535-1) The main CPU 300a loads the special symbol identification value set in step S520-1 or step S530-1 above.

[0282] (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 step S535-1 is "00H", the counter value of the special symbol 1 reserved ball counter, i.e., the number of special 1 reserved balls, is loaded. Also, if the special symbol identification value loaded in step S535-1 is "01H", the counter value of the special symbol 2 reserved ball counter, i.e., the number of special 2 reserved balls, is loaded.

[0283] (Step S535-5) The main CPU 300a loads the jackpot determination random number updated by the hardware random number generator.

[0284] (Step S535-7) The main CPU 300a determines whether the number of target special symbol reserved balls loaded in step S535-3 is equal to or greater than the upper limit. If it determines that it is equal to or greater than the upper limit, it proceeds to step S535-21; otherwise, it proceeds to step S535-9.

[0285] (Step S535-9) The main CPU 300a updates the counter value of the target special symbol ball count counter to the current counter value plus "1".

[0286] (Step S535-11) The main CPU 300a determines which of the eight memory units in the special symbol hold memory area will be used to save the acquired jackpot determination random number.

[0287] (Step S535-13) The main CPU 300a acquires the jackpot determination random number loaded in step S535-5, the winning symbol 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.

[0288] (Step S535-15) The main CPU 300a performs a special symbol reserve ball entry order setting process, which updates and stores the entry order of special symbol reserve balls 1 and 2 stored in the special symbol reserve memory area.

[0289] (Step S536) The main CPU 300a performs an acquisition-time performance determination process based on the various random numbers stored in the target memory unit in step S535-13 above, which involves a preliminary lottery for major roles, a preliminary determination of winning symbols, and a preliminary determination of variation information. In this acquisition-time performance determination process, a pre-read specification command indicating the variation information to be determined when newly stored reserved information is read is sent to the sub-control board 330. This acquisition-time performance determination process will be described later.

[0290] (Step S535-17) The main CPU 300a loads the counter values ​​for the Special Symbol 1 Reserved Ball Counter and the Special Symbol 2 Reserved Ball Counter.

[0291] (Step S535-19) The main CPU 300a sets a special symbol hold designation command in the transmission buffer based on the counter value loaded in step S535-17 above. Here, the special symbol 1 hold designation command is set based on the counter value of the special symbol 1 hold ball count counter (special 1 hold count), and the special symbol 2 hold designation command is set based on the counter value of the special symbol 2 hold ball count counter (special 2 hold count). As a result, each time a special 1 hold or special 2 hold is stored, the special 1 hold count and special 2 hold count are transmitted to the sub-control board 330.

[0292] (Step S535-21) The main CPU 300a loads the normal game management phase.

[0293] (Step S535-23) The main CPU 300a checks the normal game management phase loaded in step S535-21 and determines whether it is below the normal electric prize entry opening control state described later. If it is determined that it is below the normal electric prize entry opening control state, the process moves to step S535-25. If it is determined that it is not below the normal electric prize entry opening control state, the special symbol random number acquisition process is terminated.

[0294] (Step S535-25) The main CPU 300a determines whether or not an abnormal prize has been awarded. If it determines that an abnormal prize has been awarded, it executes a predetermined abnormal prize award error processing process at the starting gate and terminates the special symbol random number acquisition process (step S535).

[0295] Figure 28 is a flowchart illustrating the acquisition-time performance determination process (step S536) in the main control board 300 according to this embodiment.

[0296] (Step S536-1) The main CPU 300a selects a corresponding jackpot determination random number table based on the currently set settings. Specifically, it selects a corresponding jackpot determination random number table based on the current game state and the currently set settings. Then, based on the selected table and the jackpot determination random number stored in the target memory unit in step S535-13 above, it performs a special symbol win provisional determination process to provisionally determine whether it is a jackpot, a minor win, or a miss.

[0297] (Step S536-3) The main CPU 300a executes a special symbol provisional determination process to provisionally determine the special symbols. Here, if the result of the provisional big win lottery in step S536-1 (the result derived by the special symbol provisional win determination process) is a big win or a small win, the system loads the winning symbol random number, the winning type (whether it is a big win or a small win), and the hold type stored in the target memory in step S535-13, selects the corresponding winning symbol random number determination table, extracts the special symbol determination data, and saves the extracted special symbol determination data (type of big win or small win symbol). If the result of the provisional big win lottery in step S536-1 is a miss, the system saves the predetermined special symbol determination data for misses (type of miss symbol).

[0298] (Step S536-5) The main CPU 300a sets the pre-read symbol type specification command (pre-read specification command) corresponding to the special symbol judgment data saved in step S536-3 into the transmission buffer.

[0299] (Step S536-7) The main CPU 300a determines whether the result derived from the special symbol win provisional determination process in step S536-1 is a big win or a small win. If it determines that it is a big win or a small win, it proceeds to step S536-9; if it determines that it is neither a big win nor a small win (i.e., a loss), it proceeds to step S536-11.

[0300] (Step S536-9) The main CPU 300a sets the random number determination table for determining the reach mode during a big win (see Figures 9(b) and (c)) or the random number determination table for determining the reach mode during a small win (Figures 9(d) and (e)), and then proceeds to step S536-19.

[0301] (Step S536-11) The main CPU 300a loads the random number used to determine the reach group, which was stored in the target memory unit in step S535-13 above.

[0302] (Step S536-13) The main CPU 300a determines whether the random number used to determine the reach group loaded in step S536-11 is a fixed value (8500 or greater). Here, the group type is determined by referring to the random number determination table for determining the reach group, which is selected according to the number of reserved numbers stored. At this time, the random number used to determine the reach group is obtained from the range of 0 to 10006. If the value of the random number used to determine the reach group is 8500 or greater, the same random number determination table is selected regardless of the number of reserved numbers. If the value of the random number used to determine the reach group is less than 8500, a different random number determination table is selected according to the number of reserved numbers. Hereinafter, among the random numbers used to determine the reach group, values ​​in the range of 0 to 8499 for which a different random number determination table is selected according to the number of reserved numbers will be referred to as undefined values, and values ​​in the range of 8500 to 10006 for which the same random number determination table is selected regardless of the number of reserved numbers will be referred to as fixed values. If it is determined that the random number used to determine the reach group loaded in step S536-11 is a fixed value (8500 or greater), the process moves to step S536-15. If it is determined that the random number used to determine the reach group loaded in step S536-11 is not a fixed value (8500 or greater), the process moves to step S536-27.

[0303] (Step S536-15) The main CPU 300a sets up the reach group determination random number judgment table (see Figure 8). Note that there are multiple types of reach group determination random number judgment tables depending on the number of reserved numbers, but here, the table used when the number of reserved numbers is 0 is selected. Then, based on the set reach group determination random number judgment table and the reach group determination random number stored in the target memory unit in step S535-13 above, the reach group (group type) is provisionally determined.

[0304] (Step S536-17) The main CPU 300a sets a random number determination table for determining the reach mode when a loss occurs (see Figure 9(a)) corresponding to the group type provisionally determined in step S536-15 above, and then moves the process to step S536-19.

[0305] (Step S536-19) The main CPU 300a provisionally determines the variation mode number based on the reach mode determination random number judgment table set in step S536-9 or step S536-17 and the reach mode determination random number stored in the target memory in step S535-13. At this point, along with the variation mode number, the variation pattern random number judgment table is also provisionally determined.

[0306] (Step S536-21) The main CPU 300a sets a look-ahead specified variable mode command (look-ahead specified command) corresponding to the variable mode number provisionally determined in step S536-19 above into the transmit buffer.

[0307] (Step S536-23) The main CPU 300a provisionally determines the variation pattern number based on the variation pattern random number determination table provisionally determined in step S536-19 and the variation pattern random numbers stored in the target memory unit in step S535-13.

[0308] (Step S536-25) The main CPU 300a sets the pre-read specified variation pattern command (pre-read specified command) corresponding to the variation pattern number provisionally determined in step S536-23 above into the transmission buffer, and terminates the acquisition time performance determination process.

[0309] (Step S536-27) The main CPU 300a sets an undefined value command (pre-read specified variation mode command and pre-read specified variation pattern command = 7FH) in the transmission buffer for newly stored hold data in the target memory unit, indicating that the group type, i.e., the variation pattern, will change according to the number of hold data at the time the hold data is read, and then terminates the performance determination process at the time of acquisition.

[0310] Figure 29 is a diagram illustrating the special game management phase according to this embodiment. As already explained, in this embodiment, a special game triggered by the entry of a game ball into the first start port 120 or the second start port 122, and a normal game triggered by the passage of a game ball through the gate 124 (entry of a game ball into the normal operation port 125) proceed simultaneously. The processing related to the special game is executed in stages and repeatedly, and the main control board 300 manages each of these special game-related processes through the special game management phase.

[0311] As shown in Figure 29, the main ROM 300b stores multiple special game control modules for executing and controlling special games, and each of these special game control modules is associated with a special game management phase. Specifically, if the special game management phase is "00H", a module for executing the "special symbol variation waiting process" is called; if the special game management phase is "01H", a module for executing the "special symbol variation in progress process" is called; if the special game management phase is "02H", a module for executing the "special symbol stop symbol display process" is called; if the special game management phase is "03H" or "07H", a module for executing the "pre-opening process for the big prize slot" is called; if the special game management phase is "04H" or "08H", a module for executing the "big prize slot opening control process" is called; if the special game management phase is "05H" or "09H", a module for executing the "big prize slot closing valid process" is called; and if the special game management phase is "06H" or "0AH", a module for executing the "big prize slot closing wait process" is called.

[0312] Figure 30 is a flowchart illustrating the special game management process (step S600) in the main control board 300.

[0313] (Step S600-1) The main CPU 300a loads the special game management phase.

[0314] (Step S600-3) The main CPU 300a selects the special game control module corresponding to the special game management phase loaded in step S600-1 above.

[0315] (Step S600-5) The main CPU 300a calls the special game control module selected in step S600-3 above and starts processing.

[0316] (Step S600-7) The main CPU 300a loads the special game timer, which manages the control time for special games, and then terminates the special game management process.

[0317] Figure 31 is a flowchart illustrating the special symbol variation waiting process in the main control board 300. This special symbol variation waiting process is executed when the special game management phase is "00H".

[0318] (Step S610-1) The main CPU 300a determines whether the counter value of the special symbol 2 reserved ball counter, i.e., the special 2 reserved ball count (X2), is "1" or greater. If it determines that the special 2 reserved ball count (X2) is "1" or greater, the process moves to step S610-7; if it determines that the special 2 reserved ball count (X2) is not "1" or greater, the process moves to step S610-3.

[0319] (Step S610-3) The main CPU 300a determines whether the counter value of the special symbol 1 reserved ball counter, i.e., the special 1 reserved ball count (X1), is "1" or greater. If it determines that the special 1 reserved ball count (X1) is "1" or greater, the process moves to step S610-7; if it determines that the special 1 reserved ball count (X1) is not "1" or greater, the process moves to step S610-5.

[0320] (Step S610-5) The main CPU 300a sets the customer waiting command in the transmission buffer, executes the customer waiting setting process to set the machine to a customer waiting state, and then terminates the special symbol variation waiting process.

[0321] (Step S610-7) The main CPU 300a blocks the special symbol 2 reserved balls stored in the first to fourth memory units of the second special symbol reserved ball storage area, or the special symbol 1 reserved balls stored in the first to fourth memory units of the first special symbol reserved ball storage area, to the memory unit with the smaller ordinal number. Specifically, in step S610-1 above, if it is determined that the number of special symbol 2 reserved balls is "1" or more, the special symbol 2 reserved balls stored in the second to fourth memory units of the second special symbol reserved ball storage area are transferred to the first to third memory units. In addition, the main RAM 300c is provided with a memory unit 0 to be processed, and the special symbol 2 reserved balls stored in the first memory unit are block-transferred to the memory unit 0. Furthermore, in step S610-3 above, if it is determined that the number of special symbol 1 reserved balls is "1" or more, the special symbol 1 reserved balls stored in the second to fourth memory units of the first special symbol reserved ball storage area are transferred to the first to third memory units, and the special symbol 1 reserved balls stored in the first memory unit are block-transferred to the zero memory unit. In this special symbol storage area shift process, the counter value of the target special symbol reserved ball count counter corresponding to the reserved ball type transferred to the zero memory unit is deducted by "1", and a reserved ball reduction specification command indicating that the special symbol 1 reserved balls or special symbol 2 reserved balls have been reduced by "1" is set in the transmission buffer.

[0322] (Step S611) The main CPU 300a executes a special symbol win determination process for the major prize lottery. This special symbol win determination process will be described later.

[0323] (Step S610-11) The main CPU 300a executes a special symbol determination process to determine the special symbols. Here, if the determination information (lottery result of the major role lottery) stored in step S611 is a big win or a minor win, the winning type (whether it is a big win or a minor win) and the hold type are loaded, and the corresponding winning symbol random number determination table is set. Then, referring to the set winning symbol random number determination table, the special symbol determination data is extracted using the winning symbol random number transferred to the 0th memory unit, and the extracted special symbol determination data (type of big win symbol or minor win symbol) is saved. On the other hand, if the lottery result of the major role lottery stored in step S611 is a miss, if the hold type is special 1 hold, special symbol X is saved as a miss, and if the hold type is special 2 hold, special symbol Y is saved as a miss. Here, a symbol type specification command corresponding to the saved special symbol determination data is set in the transmit buffer.

[0324] (Step S610-13) The main CPU 300a saves the special symbol stop symbol number corresponding to the special symbol judgment data extracted in step S610-11 above. 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 ultimately light up.

[0325] (Step S612) The main CPU 300a executes a special symbol variation number determination process that determines the variation mode number and variation pattern number. Details of this special symbol variation number determination process will be described later.

[0326] (Step S610-15) The main CPU 300a loads the variation mode number and variation pattern number determined in step S612 above, and determines variation time 1 and variation time 2 by referring to the variation time determination table. Then, it sets the total duration of the determined variation times 1 and 2 in the special symbol variation timer.

[0327] (Step S610-17) The main CPU 300a performs a reserve area setting process, which includes storing the game state when a major role lottery is executed in the game state buffer. In this reserve area setting process, if the result of the major role lottery is a jackpot, it stores game state information to be set after the major role game, the type of jackpot symbol (special symbol judgment data), etc., in the reserve area of ​​the main RAM 300c.

[0328] (Step S610-19) The main CPU 300a executes a process to set the special symbol display counter in order to start the variable display of special symbols in the first special symbol display unit 160 or the second special symbol display unit 162. Each segment of the 7-segment display that makes up the first special symbol display unit 160 and the second special symbol display unit 162 is associated with a counter value, 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 when the variable display of special symbols starts is set in the special symbol display counter. Note that the special symbol display counter is provided separately as a special symbol 1 display counter corresponding to the first special symbol display unit 160 and a special symbol 2 display counter corresponding to the second special symbol display unit 162, and here, the counter value is set in the counter corresponding to the hold type.

[0329] (Step S610-21) The main CPU 300a loads the counter values ​​of the Special Symbol 1 Reserve Ball Count Counter and the Special Symbol 2 Reserve Ball Count Counter, and sets the Special Symbol Reserve Designation Command in the transmission buffer. Here, the Special Symbol 1 Reserve Designation Command is set based on the counter value of the Special Symbol 1 Reserve Ball Count Counter (Special Symbol 1 Reserve Count), and the Special Symbol 2 Reserve Designation Command is set based on the counter value of the Special Symbol 2 Reserve Ball Count Counter (Special Symbol 2 Reserve Count). Also here, the Special Symbol Winning Order Command, corresponding to the winning order of the Special Symbol 1 Reserve and Special Symbol 2 Reserve stored in step S610-7 above, is set in the transmission buffer. As a result, each time a Special Symbol 1 Reserve or Special Symbol 2 Reserve is consumed, the number of Special Symbol 1 Reserves and Special Symbol 2 Reserves, as well as the winning order of each of these Reserves, are transmitted to the sub-control board 330.

[0330] (Step S610-23) The main CPU 300a updates the special game management phase to "01H" and terminates the special symbol variation waiting process.

[0331] Figure 32 is a flowchart illustrating the special symbol hit detection process (S611) according to this embodiment.

[0332] (Step S611-1) The main CPU 300a loads the special symbol probability state flag.

[0333] (Step S611-3) The main CPU 300a loads the registered settings from the settings buffer.

[0334] (Step S611-5) The main CPU 300a determines whether the registered setting value loaded in step S611-3 is within the normal range. If it determines that the value is within the normal range, it proceeds to step S611-11; otherwise, it proceeds to step S611-7.

[0335] (Step S611-7) The main CPU 300a sets the gaming machine status flag to 03H (setting abnormal state).

[0336] (Step S611-9) The main CPU 300a sets a setting error status command (subcommand) in the transmission buffer and terminates the special symbol hit detection process. When this setting error status command is transmitted to the sub-control board 330, a notification indicating a setting error is issued.

[0337] (Step S611-11) The main CPU 300a refers to the jackpot determination random number judgment table corresponding to the information loaded in steps S611-1 and S611-3 above, and sets the lower limit and upper limit values, respectively, for determining whether it is a jackpot or a minor win.

[0338] (Step S611-13) The main CPU 300a compares the jackpot determination random number transferred to the 0th memory unit with the above lower and upper limits and performs a determination process (jackpot lottery) to determine whether a jackpot or a minor win has been achieved.

[0339] (Step S611-15) The main CPU 300a sets the result of the judgment process in step S611-13 as judgment information and terminates the special symbol win judgment process.

[0340] Figure 33 is a flowchart illustrating the special pattern variation number determination process in the main control board 300 according to this embodiment.

[0341] (Step S612-1) The main CPU 300a determines whether the variable pattern selection status flag is 01H or higher. If it determines that the variable pattern selection status flag is 01H or higher, it proceeds to step S612-3; if it determines that the variable pattern selection status flag is not 01H or higher, it proceeds to step S612-5.

[0342] Here, there are five types of variation pattern selection status flags: 00H, 01H, 02H, 03H, and 04H. Each variation pattern selection status flag indicates the variation state, with 00H corresponding to the normal variation state, 01H to the first variation state, 02H to the second variation state, 03H to the third variation state, and 04H to the fourth variation state. The variation state determines which table (reach group determination random number judgment table, reach mode determination random number judgment table, variation pattern random number judgment table) to select.

[0343] In the first to fourth variation states, the selection of which table to use is defined for each variation state based on the number of times the symbols are displayed in variation (number of variations). Therefore, when the variation pattern selection state flag is 01H or higher, the main CPU 300a selects a pre-set table based on both the variation pattern selection state flag and the number of variations, and then determines the variation information by referring to the selected table. On the other hand, in the normal variation state, the variation information is determined by referring to the table corresponding to the current game state, etc., regardless of the number of variations.

[0344] (Step S612-3) The main CPU 300a increments the fluctuation count counter. The fluctuation count counter is a counter that counts the number of fluctuations in the current fluctuation state.

[0345] (Step S612-5) The main CPU 300a determines whether the result of the major prize lottery in step S611 is a big win or a minor win. If it determines that it is a big win or a minor win, it proceeds to step S612-7. If it determines that it is neither a big win nor a minor win (it is a miss), it proceeds to step S612-11.

[0346] (Step S612-7) The main CPU 300a loads the variable pattern selection status flag.

[0347] (Step S612-9) If the variable pattern selection status flag loaded in step S612-7 is 01H or higher, the main CPU 300a sets a random number determination table for determining the reach mode based on the variable pattern selection status flag and the counter value of the variable count counter. If the variable pattern selection status flag loaded in step S612-7 is 00H, the main CPU 300a sets a random number determination table for determining the reach mode corresponding to the current game state and the type of hold.

[0348] (Step S612-11) If the type of the read-out hold is Special 2 hold, the main CPU 300a checks the counter value of the Special Symbol 2 hold ball count counter, and if the type of the read-out hold is Special 1 hold, it checks the counter value of the Special Symbol 1 hold ball count counter.

[0349] (Step S612-13) The main CPU 300a loads the variable pattern selection status flag.

[0350] (Step S612-15) If the variable pattern selection status flag loaded in step S612-13 is 01H or higher, the main CPU 300a sets a random number determination table for determining the reach group based on the variable pattern selection status flag, the counter value of the variable count counter, the type of hold, and the number of holds confirmed in step S612-11. On the other hand, if the variable pattern selection status flag loaded in step S612-13 is 00H, the main CPU 300a sets a corresponding random number determination table for determining the reach group based on the current game state, the number of holds confirmed in step S612-11, and the type of hold. Then, based on the set random number determination table for determining the reach group and the random number for determining the reach group transferred to the 0th memory unit in step S610-7, the main CPU 300a determines the reach group (group type).

[0351] (Step S612-17) The main CPU 300a sets up a random number determination table for determining the reach mode in case of a loss, which corresponds to the group type determined in step S612-15 above.

[0352] (Step S612-19) The main CPU 300a determines the variable mode number based on the reach mode determination random number judgment table set in step S612-9 or step S612-17 and the reach mode determination random number transferred to the 0th memory unit in step S610-7. At this point, the variable pattern random number judgment table is also determined along with the variable mode number.

[0353] (Step S612-21) The main CPU 300a sets the variable mode command corresponding to the variable mode number determined in step S612-19 above into the transmit buffer.

[0354] (Step S612-23) The main CPU 300a determines the variation pattern number based on the variation pattern random number determination table determined in step S612-19 and the variation pattern random number transferred to the 0th memory unit in step S610-7.

[0355] (Step S612-25) The main CPU 300a sets the variable pattern command corresponding to the variable pattern number determined in step S612-23 above into the transmission buffer, and terminates the special symbol variable number determination process.

[0356] Figure 34 is a flowchart illustrating the special symbol variation processing in the main control board 300 according to this embodiment. This special symbol variation processing is executed when the special game management phase is "01H".

[0357] (Step S620-1) The main CPU 300a executes the process of updating the special symbol variation base counter. The special symbol variation base counter is set so that it completes one cycle in a predetermined period (for example, 100ms). Specifically, if the counter value of the special symbol variation base counter is "0", a predetermined counter value (for example, 25) is set, and if the counter value is "1" or greater, the counter value is updated to a value obtained by subtracting "1" from the current counter value.

[0358] (Step S620-3) The main CPU 300a determines whether the counter value of the special symbol variation base counter updated in step S620-1 is "0". If the counter value is "0", the process moves to step S620-5; otherwise, the process moves to step S620-9.

[0359] (Step S620-5) The main CPU 300a performs a special symbol variation timer update process, which subtracts a predetermined value from the timer value of the special symbol variation timer set in step S610-15 above.

[0360] (Step S620-7) The main CPU 300a determines whether the timer value of the special symbol variation timer, which was updated in step S620-5 above, is "0". If the timer value is "0", the process moves to step S620-15; otherwise, the process moves to step S620-9.

[0361] (Step S620-9) The main CPU 300a updates the special symbol display timers that measure the illumination time of each segment of the 7-segment display that makes up the first special symbol display unit 160 and the second special symbol display unit 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 greater, the timer value is updated to a value obtained by subtracting "1" from the current timer value.

[0362] (Step S620-11) The main CPU 300a determines whether the timer value of the special symbol display timer is "0". If it determines that the timer value of the special symbol display timer is "0", it proceeds to step S620-13. If it determines that the timer value of the special symbol display timer is not "0", it terminates the special symbol variation process.

[0363] (Step S620-13) The main CPU 300a updates the counter value of the special symbol display counter to be updated and terminates the special symbol variation process. As a result, each segment that makes up the 7-segment display lights up sequentially at predetermined time intervals.

[0364] (Step S620-15) The main CPU 300a updates the special game management phase to "02H".

[0365] (Step S620-17) The main CPU 300a saves the special symbol stop symbol number (counter value) determined in step S610-13 above to the target special symbol display symbol counter. As a result, the determined special symbol is displayed as stopped on the first special symbol display unit 160 or the second special symbol display unit 162.

[0366] (Step S620-19) The main CPU 300a sets a special symbol stop command in the transmission buffer, indicating that a special symbol has been stopped and displayed on the first special symbol indicator 160 or the second special symbol indicator 162.

[0367] (Step S620-21) The main CPU 300a sets the special symbol variation stop time, which is the time for the special symbol to be displayed in a stopped state, to the special game timer and terminates the special symbol variation processing.

[0368] Figure 35 is a flowchart illustrating the special symbol stop symbol display process in the main control board 300 according to this embodiment. This special symbol stop symbol display process is executed when the special game management phase is "02H".

[0369] (Step S630-1) The main CPU 300a determines whether the timer value of the special game timer set in step S620-21 is not "0". If it determines that the timer value of the special game timer is not "0", it terminates the special symbol stop symbol display process. If it determines that the timer value of the special game timer is "0", it moves to step S630-3.

[0370] (Step S630-3) The main CPU 300a checks the results of the major role lottery.

[0371] (Step S630-5) The main CPU 300a determines whether the result of the major role lottery is a jackpot. If it determines that it is a jackpot, it proceeds to step S630-19; if it determines that it is not a jackpot, it proceeds to step S630-7.

[0372] (Step S630-7) The main CPU 300a executes the count limit management process. Here, it loads the special symbol probability state flag to check whether the current game state is a low probability game state or a high probability game state. If the game state is a high probability game state, it updates the high probability count limit counter value to a value obtained by subtracting "1" from the current counter value. If the high probability count limit counter value becomes "0" as a result of updating it, it sets the special symbol probability state flag corresponding to the low probability game state. As a result, in the high probability game state, once the special symbols have been confirmed a predetermined number of times without winning a jackpot, the game state will transition to the low probability game state.

[0373] Furthermore, a time-saving state flag is loaded here to identify whether the game state is a non-time-saving game state or a time-saving game state, and the current game state is checked to determine whether it is a non-time-saving game state or a time-saving game state. If the game state is a time-saving game state, the counter value of the time-saving count counter is updated to a value obtained by subtracting "1" from the current counter value. If the counter value becomes "0" as a result of updating the time-saving count counter, the time-saving state flag corresponding to a non-time-saving game state is set. As a result, in a time-saving game state, once the special symbols have been confirmed a predetermined number of times without winning a jackpot, the game state will transition to a non-time-saving game state.

[0374] (Step S631) The main CPU 300a performs a change state update process to update the change state. This change state update process will be described later using Figure 36.

[0375] (Step S630-11) The main CPU 300a sets a command to the transmission buffer that specifies the game state when a special symbol is confirmed, indicating the game state at the time the special symbol is confirmed.

[0376] (Step S630-13) The main CPU 300a sets a count command in the transmission buffer to transmit the high-probability count and time-saving count updated in step S630-7 above to the sub-control board 330.

[0377] (Step S630-15) The main CPU 300a determines whether the result of the major prize draw is a minor prize. If it determines that it is a minor prize, it proceeds to step S630-21; if it determines that it is not a minor prize, it proceeds to step S630-17.

[0378] (Step S630-17) The main CPU 300a updates the special game management phase to "00H" and terminates the special symbol stop symbol display process. As a result, the special game management process based on hold 1 is terminated, and if special hold 1 or special hold 2 is stored, processing will be performed to start the display of the special symbol variation based on the next hold.

[0379] (Step S630-19) The main CPU 300a resets (sets) the game state to its initial state, which is the low-probability game state and the non-time-saving game state.

[0380] (Step S630-21) The main CPU 300a sets the data for the special electric mechanism operation ramset table according to the type of special symbol that has been determined.

[0381] (Step S630-23) The main CPU 300a performs the process of setting the maximum number of special electric mechanism operations. Specifically, it refers to the data set in step S630-21 above and sets a predetermined number (counter value corresponding to the type of special symbol = number of rounds) as the counter value in the special electric mechanism maximum operation counter. This special electric mechanism maximum operation counter indicates the number of rounds that can be executed in the upcoming big prize game. Meanwhile, the main RAM 300c is equipped with a special electric mechanism continuous operation counter, and the current number of rounds is managed by adding "1" to the counter value of the special electric mechanism continuous operation counter at the start of each round game. At the start of the big prize game, a process to reset (update to "0") the counter value of this special electric mechanism continuous operation counter is also executed.

[0382] (Step S630-25) The main CPU 300a refers to the data set in step S630-21 above and saves a predetermined opening time as a timer value to the special game timer.

[0383] (Step S630-27) The main CPU 300a sets an opening designation command in the transmission buffer to inform the sub-control board 330 of the start of a major or minor win game. This opening designation command is set for each opening time, and in this case, the opening designation command corresponding to the opening time saved in step S630-25 above is set in the transmission buffer.

[0384] (Step S630-29) If the result of the major role lottery confirmed in step S630-3 above is a jackpot, the main CPU 300a updates the special game management phase to "07H", and if it is a minor win, it updates the special game management phase to "03H", and terminates the special symbol stop symbol display process. This starts either a jackpot game or a minor win game.

[0385] Figure 36 is a flowchart illustrating the fluctuating state update process in the main control board 300 according to this embodiment.

[0386] (Step S631-1) The main CPU 300a determines whether the variable pattern selection status flag is 01H or higher. If it determines that the variable pattern selection status flag is 01H or higher, the process moves to step S631-3; if it determines that the variable pattern selection status flag is not 01H or higher, the process moves to step S631-9.

[0387] (Step S631-3) The main CPU 300a determines whether the number of fluctuations has reached a predetermined number. If it determines that the number of fluctuations has reached the predetermined number, it proceeds to step S631-5; if it determines that the number of fluctuations has not reached the predetermined number, it proceeds to step S631-9.

[0388] (Step S631-5) The main CPU 300a resets (sets to 0) the counter value (number of changes) of the change count counter.

[0389] (Step S631-7) The main CPU 300a updates the variable pattern selection status flag to 00H.

[0390] (Step S631-9) The main CPU 300a loads the variable pattern selection status flag, sets the variable status specification command corresponding to the loaded variable pattern selection status flag, and then terminates the variable status update process.

[0391] Figure 37 is a flowchart illustrating the pre-processing for opening the main prize slot in the main control board 300 according to this embodiment. This pre-processing for opening the main prize slot is executed when the special game management phase is "03H" or "07H".

[0392] (Step S640-1) The main CPU 300a determines whether the timer value of the special game timer is not "0". If it determines that the timer value of the special game timer is not "0", it terminates the pre-processing for opening the big prize slot. If it determines that the timer value of the special game timer is "0", it proceeds to step S640-3.

[0393] (Step S640-3) The main CPU 300a updates the counter value of the special electric mechanism continuous operation count counter to the current counter value plus "1".

[0394] (Step S640-5) The main CPU 300a sets a command to specify the opening of the large prize slots in the transmission buffer to transmit to the sub-control board 330 that the first large prize slot 126 and the second large prize slot 128 have started to open (the start of the round game).

[0395] (Step S641) The main CPU 300a executes the process of switching the opening and closing of the main prize slot. This process will be explained later.

[0396] (Step S640-7) The main CPU 300a updates the special game management phase to the current value plus 01H ("04H" or "08H"), and terminates the pre-processing for opening the big prize slot.

[0397] Figure 38 is a flowchart illustrating the opening and closing switching process of the main prize slot in the main control board 300 according to this embodiment.

[0398] (Step S641-1) The main CPU 300a determines whether the counter value of the special electric mechanism opening / closing switch count counter is the upper limit of the number of times the special electric mechanism is opened and closed (the number of times the first large prize opening 126 and the second large prize opening 128 are opened and closed during one round of gameplay). If it is determined that the counter value is the upper limit, the process of opening and closing the large prize openings is terminated. If it is determined that the counter value is not the upper limit, the process moves to step S641-3.

[0399] (Step S641-3) The main CPU 300a refers to the data in the special electric mechanism operation ramset table and extracts solenoid control data for controlling the energization of the first large prize slot solenoid 126c or the second large prize slot solenoid 128c, as well as timer data which is the energization time or de-energization time of the first large prize slot solenoid 126c or the second large prize slot solenoid 128c, based on the counter value of the special electric mechanism opening / closing switch counter.

[0400] (Step S641-5) Based on the solenoid control data extracted in step S641-3 above, the main CPU 300a executes a large prize solenoid energization control process to either start energizing the first large prize solenoid 126c or the second large prize solenoid 128c, or to stop energizing the first large prize solenoid 126c or the second large prize solenoid 128c. This execution of the large prize solenoid energization control process results in the start or stop of energizing the first large prize solenoid 126c or the second large prize solenoid 128c being controlled in steps S400-31 and S400-33 above.

[0401] (Step S641-7) The main CPU 300a saves the timer value based on the timer data extracted in step S641-3 above to the special game timer. The timer value saved to the special game timer here is the maximum opening time for the first and second large prize winning slots 126 and 128 in one go.

[0402] (Step S641-9) The main CPU 300a determines whether the first large prize slot solenoid 126c or the second large prize slot solenoid 128c is in the power-on state, that is, whether the control process to start powering the first large prize slot solenoid 126c or the second large prize slot solenoid 128c was performed in step S641-5 above. If it is determined that the power-on state has been started, the process moves to step S641-11; if it is determined that the power-on state has not been started, the large prize slot opening / closing switching process is terminated.

[0403] (Step S641-11) The main CPU 300a updates the counter value of the special electric mechanism opening / closing count counter to the current counter value plus "1", and then terminates the opening / closing process for the large prize slot.

[0404] Figure 39 is a flowchart illustrating the big prize opening control process in the main control board 300 according to this embodiment. This big prize opening control process is executed when the special game management phase is "04H" or "08H".

[0405] (Step S650-1) The main CPU 300a determines whether the timer value of the special game timer saved in step S641-7 is not "0". If it determines that the timer value of the special game timer is not "0", it proceeds to step S650-5. If it determines that the timer value of the special game timer is "0", it proceeds to step S650-3.

[0406] (Step S650-3) The main CPU 300a determines whether the counter value of the special electric mechanism opening / closing switch count counter is the upper limit of the number of times the special electric mechanism can be opened / closed. If it determines that the counter value is the upper limit, the process moves to step S650-7; if it determines that the counter value is not the upper limit, the process moves to step S641.

[0407] (Step S641) In step S650-3 above, if the counter value of the special electric mechanism opening / closing switch count counter is determined not to be the upper limit of the number of times the special electric mechanism can be opened / closed, the main CPU 300a executes the process in step S641 above.

[0408] (Step S650-5) The main CPU 300a determines whether the counter value of the large prize-winning ball counter, which was updated in step S500-9 above, has reached a predetermined number, that is, whether the same number of game balls as the maximum number of balls that can be won in one round have entered the first large prize-winning ball 126 or the second large prize-winning ball 128. If it determines that the predetermined number has not been reached, the large prize-winning ball opening control process is terminated, and if it determines that the predetermined number has been reached, the process moves to step S650-7.

[0409] (Step S650-7) The main CPU 300a executes the necessary prize-winning gate closing process to close the first prize-winning gate 126 and the second prize-winning gate 128 by stopping the power supply to the first prize-winning gate solenoid 126c and the second prize-winning gate solenoid 128c. As a result, the first prize-winning gate 126 and the second prize-winning gate 128 are closed.

[0410] (Step S650-9) The main CPU 300a saves the effective closing time (interval time) for the big prize slot to the special game timer.

[0411] (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").

[0412] (Step S650-13) The main CPU 300a sets a command to specify that the first and second prize winning holes 126 and 128 have been closed, and then terminates the prize winning hole opening control process.

[0413] Figure 40 is a flowchart illustrating the process for activating the closure of the main prize slot in the main control board 300 according to this embodiment. This process for activating the closure of the main prize slot is executed when the special game management phase is "05H" or "09H".

[0414] (Step S660-1) The main CPU 300a determines whether the timer value of the special game timer saved in step S650-9 is not "0". If it determines that the timer value of the special game timer is not "0", it terminates the process of activating the closing of the big prize slot. If it determines that the timer value of the special game timer is "0", it proceeds to step S660-3.

[0415] (Step S660-3) The main CPU 300a determines whether the counter value of the special electric mechanism continuous operation count counter matches the counter value of the special electric mechanism maximum operation count counter, that is, whether the number of rounds of gameplay that have been set in advance has ended. If it is determined that the counter value of the special electric mechanism continuous operation count counter matches the counter value of the special electric mechanism maximum operation count counter, the process moves to step S660-9; if it is determined that they do not match, the process moves to step S660-5.

[0416] (Step S660-5) The main CPU 300a updates the special game management phase to "03H". Note that if the special game management phase is "05H", that is, during the control of a minor win game, the number of rounds for the minor win game is "1", so step S660-3 above will always be judged as YES, and the process will not proceed to that step.

[0417] (Step S660-7) The main CPU 300a saves the predetermined closure time for the large prize slot to the special game timer and terminates the process of activating the closure of the large prize slot. As a result, the next round of gameplay begins.

[0418] (Step S660-9) The main CPU 300a executes the ending time setting process, which saves the ending time to a special game timer.

[0419] (Step S660-11) The main CPU 300a updates the special game management phase to a value obtained by adding 01H to the current value ("06H" or "0AH").

[0420] (Step S660-13) The main CPU 300a sets an ending specification command, indicating the start of the ending, into the transmission buffer and terminates the process of activating the closing of the grand prize jackpot.

[0421] Figure 41 is a flowchart illustrating the big prize entry end wait processing in the main control board 300 according to this embodiment. This big prize entry end wait processing is executed when the special game management phase is "06H" or "0AH".

[0422] (Step S670-1) The main CPU 300a determines whether the timer value of the special game timer saved in step S660-9 is not "0". If it determines that the timer value of the special game timer is not "0", it terminates the big prize entry end wait process. If it determines that the timer value of the special game timer is "0", it proceeds to step S670-3.

[0423] (Step S670-3) The main CPU 300a executes a state setting process to determine the game state after a major win has ended. Here, the game state after a major win is set based on the winning symbols that triggered the major win. Specifically, if the winning symbols that triggered the major win were special symbols B and C, the game is set to a high-probability game state and a time-saving game state, and the number of high-probability rounds and time-saving rounds are set to 10,000. If the winning symbols that triggered the major win were special symbols A, the game is set to a low-probability game state and a time-saving game state, and the number of time-saving rounds is set to 100.

[0424] Furthermore, based on the winning symbols that triggered the major win or minor win, this process also sets the spin pattern selection status flag and the number of spins in order to determine the spin state after the major win or minor win has ended.

[0425] (Step S670-5) The main CPU 300a sets a game state change specification command in the transmission buffer to transmit the game state that will be set after the end of a major game.

[0426] (Step S670-7) The main CPU 300a sets the number of counts specified in step S670-3, which were saved in the above step, into the transmission buffer.

[0427] (Step S670-9) The main CPU 300a sets a variable state specification command in the transmission buffer to transmit the variable state that is set after the end of a major win game or a minor win game.

[0428] (Step S670-11) The main CPU 300a updates the special game management phase to "00H" and terminates the waiting process for the end of the big prize entry. As a result, if special 1 or special 2 reserves are stored, the display of the special symbols will resume.

[0429] Figure 42 is a diagram illustrating the normal game management phase according to this embodiment. As already explained, in this embodiment, the processing related to normal gameplay, triggered by the passage of a game ball through the gate 124 (entry of a game ball into the normal operation opening 125), is executed in stages and repeatedly. The main control board 300 manages each of these normal game-related processes through the normal game management phase.

[0430] As shown in Figure 42, the main ROM 300b stores multiple normal game control modules for executing and controlling normal gameplay, and each of these normal game control modules is associated with a normal game management phase. Specifically, if the normal game management phase is "00H", a module for executing the "normal symbol variation waiting process" is called; if the normal game management phase is "01H", a module for executing the "normal symbol variation in progress process" is called; if the normal game management phase is "02H", a module for executing the "normal symbol stop symbol display process" is called; if the normal game management phase is "03H", a module for executing the "normal electric prize entry opening pre-processing" is called; if the normal game management phase is "04H", a module for executing the "normal electric prize entry opening control process" is called; if the normal game management phase is "05H", a module for executing the "normal electric prize entry closing effective process" is called; and if the normal game management phase is "06H", a module for executing the "normal electric prize entry closing wait process" is called.

[0431] Figure 43 is a flowchart illustrating the normal game management process (step S700) in the main control board 300 according to this embodiment.

[0432] (Step S700-1) The main CPU 300a loads the normal game management phase.

[0433] (Step S700-3) The main CPU 300a selects the normal game control module corresponding to the normal game management phase loaded in step S700-1 above.

[0434] (Step S700-5) The main CPU 300a calls the normal game control module selected in step S700-3 above and starts processing.

[0435] (Step S700-7) The main CPU 300a loads the normal game timer, which manages the control time for normal gameplay.

[0436] Figure 44 is a flowchart illustrating the normal symbol variation waiting process in the main control board 300 according to this embodiment. This normal symbol variation waiting process is executed when the normal game management phase is "00H".

[0437] (Step S710-1) The main CPU 300a loads the counter value of the normal symbol reserve ball counter and determines whether the counter value is "0", that is, whether there are "0" normal symbol reserves. If it determines that the counter value is "0", it terminates the normal symbol variation waiting process, and if it determines that the counter value is not "0", it moves to step S710-3.

[0438] (Step S710-3) The main CPU 300a blocks the normal symbol reserves (winning random numbers) stored in the first to fourth memory units of the normal symbol reserve memory area and transfers them to the memory unit with the smaller ordinal number. Specifically, it transfers the normal symbol reserves stored in the second to fourth memory units to the first to third memory units. The main RAM 300c is also provided with a zero memory unit to be processed, and it transfers the normal symbol reserves stored in the first memory unit to the zero memory unit. During this normal symbol memory area shift process, the counter value of the normal symbol reserve ball count counter is deducted by "1", and a normal symbol reserve reduction command, indicating that the normal symbol reserve has been reduced by "1", is set in the transmission buffer.

[0439] (Step S710-5) The main CPU 300a loads the random number that determines the winning combination, which has been transferred to the 0th memory unit, selects a random number determination table that corresponds to the current game state, performs a regular symbol draw, and executes a regular symbol winning determination process that stores the result of that draw.

[0440] (Step S710-7) The main CPU 300a saves the regular symbol stop number corresponding to the result of the regular symbol lottery in step S710-5 above. In this embodiment, the regular symbol indicator 168 is composed of one LED lamp, and the regular symbol indicator 168 lights up when there is a win, and turns off when there is a loss. The regular symbol stop number determined here indicates whether or not the regular symbol indicator 168 will ultimately light up. For example, if there is a win, "0" is determined as the regular symbol stop number, and if there is a loss, "1" is determined as the regular symbol stop number.

[0441] (Step S710-9) The main CPU 300a checks the current game state and selects and sets the corresponding regular symbol variation time data table.

[0442] (Step S710-11) The main CPU 300a determines the normal symbol variation time based on the winning random number transferred to the 0th memory unit in step S710-3 and the normal symbol variation time data table set in step S710-9.

[0443] (Step S710-13) The main CPU 300a saves the normal symbol variation time determined in step S710-11 above to the normal game timer.

[0444] (Step S710-15) The main CPU 300a executes a process to set the normal symbol display counter in the normal symbol display unit 168 in order to start the display of the normal symbols in a variable state. If the counter value of this normal symbol display counter is set to, for example, "0", the normal symbol display unit 168 is controlled to light up, and if the counter value is set to "1", the normal symbol display unit 168 is controlled to turn off. Here, a predetermined counter value is set to the normal symbol display counter when the display of the normal symbols in a variable state begins.

[0445] (Step S710-17) The main CPU 300a sets a "Plant Hold Specification Command" in the transmission buffer, which indicates the number of Plan Holds stored in the Plan Hold Storage Area.

[0446] (Step S710-19) The main CPU 300a sets a normal symbol specification command in the transmission buffer based on the normal symbol stop symbol number determined in step S710-7 above, that is, the symbol type (winning symbol or losing symbol) determined by the normal symbol hit determination process.

[0447] (Step S710-21) The main CPU 300a updates the normal game management phase to "01H" and terminates the normal symbol variation waiting process.

[0448] Figure 45 is a flowchart illustrating the processing during normal symbol variation in the main control board 300 according to this embodiment. This normal symbol variation processing is executed when the normal game management phase is "01H".

[0449] (Step S720-1) The main CPU 300a determines whether the timer value of the normal game timer saved in step S710-13 is "0". If the timer value is "0", the process moves to step S720-9; otherwise, the process moves to step S720-3.

[0450] (Step S720-3) The main CPU 300a updates the regular symbol display timer, which measures the on-time and off-time of the regular symbol display unit 168. Specifically, if the timer value of the regular symbol display timer is "0", a predetermined timer value is set, and if the timer value is "1" or greater, the timer value is updated to a value obtained by subtracting "1" from the current timer value.

[0451] (Step S720-5) The main CPU 300a determines whether the timer value of the normal symbol display timer is "0". If it determines that the timer value of the normal symbol display timer is "0", it proceeds to step S720-7. If it determines that the timer value of the normal symbol display timer is not "0", it terminates the normal symbol variation process.

[0452] (Step S720-7) The main CPU 300a updates the counter value of the normal symbol display counter. Here, if the counter value of the normal symbol display counter was a value indicating that the normal symbol display unit 168 was off, it is updated to a value indicating that it was on. If the counter value was indicating that the normal symbol display unit 168 was on, it is updated to a value indicating that it was off, and the normal symbol variation process is terminated. As a result, the normal symbol display unit 168 will repeatedly turn on and off (blink) at predetermined time intervals throughout the normal symbol variation time.

[0453] (Step S720-9) The main CPU 300a saves the regular symbol stop symbol number (counter value) determined in step S710-7 above to the regular symbol display symbol counter. As a result, the regular symbol display unit 168 is ultimately controlled to light up or turn off, and the result of the regular symbol lottery is announced.

[0454] (Step S720-11) The main CPU 300a sets the normal symbol change stop time, which is the time it takes for the normal symbols to stop displaying, to the normal game timer.

[0455] (Step S720-13) The main CPU 300a sets a normal symbol stop command in the transmit buffer, indicating that the normal symbol stop display has started.

[0456] (Step S720-15) The main CPU 300a updates the normal game management phase to "02H" and terminates the processing during the normal symbol variation.

[0457] Figure 46 is a flowchart illustrating the normal symbol stop symbol display process in the main control board 300 according to this embodiment. This normal symbol stop symbol display process is executed when the normal game management phase is "02H".

[0458] (Step S730-1) The main CPU 300a determines whether the timer value of the normal game timer set in step S720-11 is not "0". If it determines that the timer value of the normal game timer is not "0", it terminates the normal symbol stop symbol display process. If it determines that the timer value of the normal game timer is "0", it moves to step S730-3.

[0459] (Step S730-3) The main CPU 300a checks the results of the general lottery.

[0460] (Step S730-5) The main CPU 300a determines whether the result of the lottery is a win. If it determines that it is a win, it proceeds to step S730-9; if it determines that it is not a win (it is a loss), it proceeds to step S730-7.

[0461] (Step S730-7) The main CPU 300a updates the normal game management phase to "00H" and terminates the normal symbol stop and symbol display processing. As a result, the normal game management processing based on the 1 normal symbol hold is terminated, and if a normal symbol hold is stored, processing is performed to start the display of the changing normal symbols based on the next hold.

[0462] (Step S730-9) The main CPU 300a refers to the data in the opening / closing control pattern table and saves the time before the normal power is opened as a timer value to the normal game timer.

[0463] (Step S730-11) The main CPU 300a updates the normal game management phase to "03H" and terminates the normal symbol stop symbol display process. As a result, the opening and closing control of the second start port 122 begins.

[0464] Figure 47 is a flowchart illustrating the pre-processing for opening the normal electric prize winning slot in the main control board 300 according to this embodiment. This pre-processing for opening the normal electric prize winning slot is executed when the normal game management phase is "03H".

[0465] (Step S740-1) The main CPU 300a determines whether the timer value of the normal game timer is not "0". If it determines that the timer value of the normal game timer is not "0", it terminates the pre-processing for opening the normal electric prize entry point. If it determines that the timer value of the normal game timer is "0", it proceeds to step S741.

[0466] (Step S741) The main CPU 300a executes the process of switching the opening and closing of the standard electric prize slot. This process of switching the opening and closing of the standard electric prize slot will be described later.

[0467] (Step S740-3) The main CPU 300a updates the normal game management phase to "04H" and terminates the pre-processing for opening the normal electric prize entry point.

[0468] Figure 48 is a flowchart illustrating the switching process for opening and closing the ordinary electric prize slot in the main control board 300 according to this embodiment.

[0469] (Step S741-1) The main CPU 300a determines whether the counter value of the normal electric mechanism opening / closing count counter is the upper limit of the normal electric mechanism opening / closing count (the number of times the movable piece 122b opens and closes during one opening / closing control). If it determines that the counter value is the upper limit, the normal electric mechanism prize entry opening / closing switching process is terminated. If it determines that the counter value is not the upper limit, the process moves to step S741-3.

[0470] (Step S741-3) The main CPU 300a refers to the data in the opening / closing control pattern table and extracts solenoid control data (power supply control data or power supply deactivation control data) for controlling the power supply of the ordinary electric mechanism solenoid 122c, and timer data which is the power supply time (solenoid power supply time) or power supply deactivation time (ordinary power closing effective time = pause time) of the ordinary electric mechanism solenoid 122c, based on the counter value of the ordinary electric mechanism opening / closing switch count counter.

[0471] (Step S741-5) Based on the solenoid control data extracted in step S741-3 above, the main CPU 300a executes a solenoid power supply control process to either start or stop the power supply to the solenoid 122c. This solenoid power supply control process allows for the start or stop of power supply to the solenoid 122c in steps S400-31 and S400-33.

[0472] (Step S741-7) The main CPU 300a saves the timer value based on the timer data extracted in step S741-3 above to the normal game timer. The timer value saved to the normal game timer here is the maximum opening time of the second start opening 122 in one go.

[0473] (Step S741-9) The main CPU 300a determines whether the standard electric prize solenoid 122c is in the power-on state, that is, whether the control process to start powering the standard electric prize solenoid 122c was performed in step S741-5 above. If it is determined that the power-on state is in place, the process moves to step S741-11; if it is determined that the power-on state is not in place, the standard electric prize entry opening opening / closing switching process is terminated.

[0474] (Step S741-11) The main CPU 300a updates the counter value of the normal electric mechanism opening / closing count counter to the current counter value plus "1".

[0475] Figure 49 is a flowchart illustrating the control process for opening the normal electric prize slot in the main control board 300 according to this embodiment. This control process for opening the normal electric prize slot is executed when the normal game management phase is "04H".

[0476] (Step S750-1) The main CPU 300a determines whether the timer value of the normal game timer saved in step S741-7 is not "0". If it determines that the timer value of the normal game timer is not "0", it proceeds to step S750-5. If it determines that the timer value of the normal game timer is "0", it proceeds to step S750-3.

[0477] (Step S750-3) The main CPU 300a determines whether the counter value of the normal electric mechanism opening / closing switch count counter is the upper limit of the normal electric mechanism opening / closing switch count. If it determines that the counter value is the upper limit, the process moves to step S750-7; if it determines that the counter value is not the upper limit, the process moves to step S741.

[0478] (Step S741) In step S750-3 above, if the counter value of the normal electric mechanism opening / closing count counter is determined not to be the upper limit of the normal electric mechanism opening / closing count, the main CPU 300a executes the process of step S741 above.

[0479] (Step S750-5) The main CPU 300a determines whether the counter value of the ordinary electric prize ball entry counter, which was updated in step S530-9 above, has reached a specified number, that is, whether the same number of game balls as the maximum number of prize balls that can be entered during one opening and closing control have entered the second start opening 122. If it determines that the specified number has not been reached, the ordinary electric prize entry opening control process is terminated, and if it determines that the specified number has been reached, the process moves to step S750-7.

[0480] (Step S750-7) The main CPU 300a executes the necessary process to close the second start port 122 by stopping the power supply to the ordinary electric mechanism solenoid 122c. As a result, the second start port 122 is closed.

[0481] (Step S750-9) The main CPU 300a saves the normal power-on state time to the normal game timer.

[0482] (Step S750-11) The main CPU 300a updates the normal game management phase to "05H" and terminates the normal electric prize entry opening control process.

[0483] Figure 50 is a flowchart illustrating the process for activating the closing of the ordinary electric prize entry slot in the main control board 300 according to this embodiment. This process for activating the closing of the ordinary electric prize entry slot is executed when the ordinary game management phase is "05H".

[0484] (Step S760-1) The main CPU 300a determines whether the timer value of the normal game timer saved in step S750-9 is not "0". If it determines that the timer value of the normal game timer is not "0", it terminates the normal electric prize entry opening closing process. If it determines that the timer value of the normal game timer is "0", it proceeds to step S760-3.

[0485] (Step S760-3) The main CPU 300a saves the normal power end wait time to the normal game timer.

[0486] (Step S760-5) The main CPU 300a updates the normal game management phase to "06H" and terminates the normal electric prize entry opening closing process.

[0487] Figure 51 is a flowchart illustrating the normal electric prize entry point end-wait processing in the main control board 300 according to this embodiment. This normal electric prize entry point end-wait processing is executed when the normal game management phase is "06H".

[0488] (Step S770-1) The main CPU 300a determines whether the timer value of the normal game timer saved in step S760-3 is not "0". If it determines that the timer value of the normal game timer is not "0", it terminates the normal electric prize entry point end wait process. If it determines that the timer value of the normal game timer is "0", it proceeds to step S770-3.

[0489] (Step S770-3) The main CPU 300a updates the normal game management phase to "00H" and terminates the normal electric prize entry point end wait processing. As a result, if a normal symbol hold is stored, the display of the normal symbol fluctuations will resume.

[0490] As described above, special games and regular games proceed as various processes are executed on the main control board 300. During the progress of these games, the sub-control board 330 performs various effects based on commands transmitted from the main control board 300. An example of an effect is described below.

[0491] Figure 52 illustrates an example of a variation animation for a variation pattern without a reach according to this embodiment. As described above, when a major prize lottery is performed on the main control board 300, a variation animation that notifies the result of the major prize lottery is executed during the variation display of the special symbols, that is, for the duration of the variation of the special symbols. In this variation animation, various background images are displayed on the main animation display unit 200a, and the animation symbols 210a, 210b, and 210c are displayed superimposed on these background images. During the variation animation, sound is output from the sound output device 206 in accordance with the image displayed on the main animation display unit 200a, the animation lighting device 204 is controlled to light up, and the animation mechanism device 202 is controlled to move, but a detailed explanation is omitted here.

[0492] The variation effects according to this embodiment are broadly classified into a no-reach variation pattern and a reach variation pattern. In the no-reach variation pattern variation effect, a background image (not shown) is displayed on the main effect display unit 200a, and the effect symbols 210a, 210b, and 210c are superimposed on this background image and displayed in a variation manner. For example, as shown in Figure 52(a), suppose the effect symbols 210a, 210b, and 210c are displayed in a combination that indicates that the big win lottery result was a miss. In this state, when a variation display of a special symbol is newly performed, the three effect symbols 210a, 210b, and 210c begin to change (scroll) as shown in Figure 52(b) along with the start of the variation display of the special symbol. Note that the downward-pointing white arrow in the figure indicates that the effect symbols 210a, 210b, and 210c are scrolled in the height direction.

[0493] Then, as shown in Figure 52(c), the special symbol 210a is displayed first, and then, as shown in Figure 52(d), a special symbol 210c, which is different from special symbol 210a, is displayed. At almost the same time that the special symbol display ends and the special symbol is displayed in the first special symbol display 160 or the second special symbol display 162, the special symbol 210b is displayed, as shown in Figure 52(e), and the result of the big prize lottery is announced to the player based on the final display patterns of the three special symbols 210a, 210b, and 210c.

[0494] Figure 53 is a diagram illustrating an example of the variation animation of a normal reach variation pattern according to this embodiment. In this embodiment, the reach variation patterns are broadly classified into a normal reach variation pattern, an advanced reach variation pattern, and a pseudo-continuous reach variation pattern. The variation animation of the normal reach variation pattern is similar to that of the no-reach variation pattern, and the variation display of the animation symbols 210a, 210b, and 210c begins when the variation display of the special symbols starts, and as shown in Figure 53(a), the animation symbol 210a is displayed first. Then, as shown in Figure 53(b), the animation symbol 210c, which is the same as the animation symbol 210a, is displayed.

[0495] As shown in Figure 53(c), when the same performance symbols 210a and 210c are displayed in a reach pattern on the main performance display unit 200a, the word "Reach" is displayed superimposed on the performance symbols 210a and 210c on the main performance display unit 200a. There are multiple types of reach patterns, and the same performance symbols 210a and 210c, each bearing one of the numbers from "1" to "9", are displayed in a reach pattern. Subsequently, as shown in Figure 53(d), the shape of the performance symbols 210a and 210c is changed from before the reach pattern, and the display continues to change. Finally, as shown in Figure 53(e), a performance symbol 210b, which is different from the performance symbols 210a and 210c, is displayed, informing the player that the result of the big win lottery was a loss.

[0496] Figure 54 is a diagram illustrating an example of the variation animation of the development reach variation pattern when a miss occurs according to this embodiment, and Figure 55 is a diagram illustrating an example of the variation animation of the development reach variation pattern when a jackpot occurs according to this embodiment. In the variation animation of the development reach variation pattern, as shown in Figures 54(a) to (d) and Figures 55(a) to (d), similar to the variation animation of the normal reach variation pattern, the animation symbols 210a and 210c are displayed in a reach pattern on the main animation display unit 200a, and then a predetermined development image (video) is played and displayed in a reach development animation. In this reach development animation, for example, as shown in Figures 54(e) and 55(e), a mission is displayed on the main animation display unit 200a, and as shown in Figures 54(f), (g) and 55(f), (g), images toward achieving the mission are displayed.

[0497] Here, the development images for the reach development sequence are broadly divided into losing patterns and winning patterns. In the losing pattern development image, as shown in Figure 54(h), an image indicating the failure of the mission is ultimately displayed, and then, as shown in Figure 54(i), the performance symbols 210a, 210b, and 210c stop and display in a combination that indicates a loss. On the other hand, in the winning pattern development image, as shown in Figure 55(h), an image indicating the success of the mission is ultimately displayed, and then, as shown in Figure 55(i), the performance symbols 210a, 210b, and 210c stop and display in a combination that indicates a win.

[0498] Furthermore, the reach development sequences include, for example, mission sequences that display development images showing the content of the mission, and battle sequences that display development images showing an ally character and an enemy character fighting. The mission sequences have multiple execution patterns with different mission content, and the battle sequences have multiple execution patterns with different characters and fighting methods. As mentioned above, the execution patterns of the mission sequences are broadly divided into jackpot patterns where the mission is completed and losing patterns where the mission is failed, and similarly, the execution patterns of the battle sequences are broadly divided into jackpot patterns where the ally character defeats the enemy character and losing patterns where the ally character is defeated by the enemy character.

[0499] The winning and losing patterns are identical in content until the final stages of the animation, differing only in whether the ally character wins or loses, or whether the mission is completed or not. Therefore, during the reach development animation, the player cannot determine the result of the big win lottery until the final stages of the variation animation, thus creating a sense of anticipation for a big win.

[0500] The winning pattern is selected only if the result of the major role lottery is a jackpot, and the losing pattern is selected only if the result of the major role lottery is a loss. However, it is possible for the reach development animation to be executed twice in a single spinning animation. In this case, the first reach development animation will be executed as a losing pattern, and the second reach development animation will be executed as either a losing pattern or a jackpot pattern. The following describes the flow of the animation when the reach development animation is executed twice in a single spinning animation.

[0501] Figure 56 illustrates an example of a variation animation when the reach development animation according to this embodiment is executed twice. For example, suppose that after the animation symbols 210a and 210c are displayed in a reach pattern, the mission animation is executed as shown in Figures 56(a) and (b). Up to this point, there is no difference from the case where the reach development animation is executed only once in one variation animation, but immediately after it is announced that the mission was not completed, "REACH UP" is displayed on the main animation display unit 200a as shown in Figure 56(c).

[0502] Subsequently, as shown in Figure 56(d), the main display unit 200a shows an advanced image for the battle sequence, and the second reach sequence begins. This advanced image for the battle sequence depicts a battle between an ally character and an enemy character. When a jackpot is won, as shown in Figure 56(e), the ally character ultimately defeats the enemy character, and as shown in Figure 56(f), the symbols 210a, 210b, and 210c stop and display in a combination that indicates a jackpot. On the other hand, when a jackpot is lost, as shown in Figure 56(g), the ally character ultimately loses to the enemy character, and as shown in Figure 56(h), the symbols 210a, 210b, and 210c stop and display in a combination that indicates a loss.

[0503] Figure 57 illustrates an example of the variation animation of the pseudo-continuous reach variation pattern according to this embodiment. As shown in Figure 57(a), when the variation display of the animation symbols 210a, 210b, and 210c begins, as shown in Figure 57(b), the animation symbols 210a, 210b, and 210c are temporarily stopped and displayed in one of a plurality of pre-defined pseudo-modes. One such pseudo-mode is, for example, the same animation symbols 210a and 210b, and animation symbol 210c, which has a number "2" greater than these animation symbols 210a and 210b, are temporarily stopped and displayed.

[0504] When the symbols 210a, 210b, and 210c are temporarily stopped in a pseudo-mode, the display of the changing symbols 210a, 210b, and 210c resumes, as shown in Figure 57(c). In other words, the pseudo-mode indicates the re-display of the changing symbols 210a, 210b, and 210c. Subsequently, as shown in Figure 57(d), the symbols 210a, 210b, and 210c are once again temporarily stopped in a pseudo-mode.

[0505] Then, as shown in Figure 57(e), when the display of the animation symbols 210a, 210b, and 210c resumes, the animation symbols 210a and 210c are displayed in a reach pattern, as shown in Figure 57(f). Thereafter, as shown in Figures 57(g) to (i), a reach development animation is performed in the same way as the development reach variation pattern, and the result of the big win lottery is announced to the player.

[0506] Thus, the variation animation of the pseudo-continuous reach variation pattern differs from that of the development reach variation pattern in that the content of the animation leading up to the reach pattern of the animation symbols 210a and 210c is different, and after the reach pattern is reached, the variation animation proceeds in the same way as the development reach variation pattern.

[0507] In the pseudo-continuous reach variation pattern, there are multiple variation display patterns for the performance symbols 210a, 210b, and 210c until the reach pattern is reached. Each variation display pattern differs in the number of times the performance symbols 210a, 210b, and 210c are temporarily stopped (displayed), or in other words, the number of times the performance symbols 210a, 210b, and 210c are displayed in variation. This variation display pattern is determined by the variation mode command, and the selection ratio of the variation mode command when a jackpot is won and when a jackpot is lost is set so that the more times the performance symbols 210a, 210b, and 210c are temporarily stopped (displayed in variation), the higher the probability (hereinafter referred to as "reliability") that a jackpot will be announced in the end.

[0508] Specifically, if the result of the major role lottery is a jackpot, the selection ratio of variable mode commands with a high number of display occurrences is set higher than the selection ratio of variable mode commands with a low number of display occurrences. Conversely, if the result of the major role lottery is a loss, the selection ratio of variable mode commands with a low number of display occurrences is set higher than the selection ratio of variable mode commands with a high number of display occurrences.

[0509] Furthermore, the main control board 300 is set so that the reliability of the pseudo-continuous reach variation pattern is higher than the reliability of the development reach variation pattern. Therefore, the reliability is indicated by the number of times the performance symbols 210a, 210b, and 210c are temporarily stopped (varied), and the player watches the outcome of the performance while hoping that the performance symbols 210a, 210b, and 210c will be temporarily stopped (varied) more often.

[0510] The execution patterns for the variation effects described above are determined and executed by the sub-control board 330 based on the variation commands determined by the main control board 300. In other words, the execution patterns for the variation effects are determined collaboratively by the main control board 300 and the sub-control board 330.

[0511] Figure 58 illustrates the variable performance determination table according to this embodiment, with Figure 58(a) showing the first half variable performance determination table and Figure 58(b) showing the second half variable performance determination table. As described above, when a major role lottery is performed on the main control board 300, a variable command is determined based on the result of the major role lottery, and each determined command is transmitted to the sub-control board 330. When the sub-control board 330 receives a variable mode command, it obtains a random performance number of 1 from the range of 0 to 249, and, referring to the first half variable performance determination table, determines the execution pattern of the first half variable performance based on the obtained random performance number and the received variable mode command. Furthermore, when it receives a variable pattern command, it obtains a random performance number of 1 from the range of 0 to 249, and, referring to the second half variable performance determination table, determines the execution pattern of the second half variable performance based on the obtained random performance number and the received variable pattern command. Note that in Figure 58, only a portion of the first half variable performance determination table and the second half variable performance determination table are shown.

[0512] As shown in Figure 58, according to the first-half variation performance determination table, a selection ratio for the execution pattern of the first-half variation performance is set for each variation mode number (variation mode command), and according to the second-half variation performance determination table, a selection ratio for the execution pattern of the second-half variation performance is set for each variation pattern number (variation pattern command). Then, by combining the determined execution patterns of the first and second halves of the variation performance, one variation performance is executed.

[0513] The variation animation for the no-reach variation pattern is executed when, as the execution pattern for the first half, "None" is determined, indicating that the variation animation for the first half will not be executed, and as the execution pattern for the second half, one of the following is determined: "Normal Miss 1", "Normal Miss 2", "Special Miss 1", or "Special Miss 2", which corresponds to the no-reach variation pattern. For example, when a variation mode command corresponding to the variation mode number "01H", which indicates that the variation animation for the first half will not be executed, is received, the sub-control board 330 will always determine "None" as the execution pattern for the first half. At the same time, the selection ratio is set in the second half variation animation determination table so that only one of the following can be determined from the variation pattern commands that can be received simultaneously: "Normal Miss 1", "Normal Miss 2", "Special Miss 1", or "Special Miss 2". Therefore, when "None" is determined as the execution pattern for the first half, and one of the following is determined as the execution pattern for the second half, the execution pattern for the variation animation will be determined to be the no-reach variation pattern described above.

[0514] On the other hand, the variation animation for the reach variation pattern is executed when a pattern other than "none" is determined as the execution pattern for the first half, and one of the reach development animations (shown as Development 1 to 5 in the diagram) is determined as the execution pattern for the second half. In other words, when the variation animation for the reach variation pattern is executed in the main animation display unit 200a, it has always received a variation mode command corresponding to a variation mode number other than variation mode number = 01H, and a variation pattern command corresponding to a variation pattern number that determines one of Development 1 to 5.

[0515] In Figure 58(a), "Normal Reach 1" and "Normal Reach 2" in the first half of the execution pattern refer to the background images and the variation display patterns of the performance symbols 210a, 210b, and 210c displayed on the main performance display unit 200a until the performance symbols 210a, 210b, and 210c appear in a reach pattern, or more specifically, until the reach development performance begins. These image patterns are pre-designed to match the timing of the variation display of the special symbols associated with the variation mode number. For example, when "Normal Reach 1" is determined, the images shown in Figures 53(a) to (d) will be displayed on the main performance display unit 200a.

[0516] Furthermore, in Figure 58(a), "Pseudo 2a" and the like in the first half of the execution patterns indicate the display pattern of the main variation animation image displayed on the main animation display unit 200a, that is, the execution pattern of the animation symbols 210a, 210b, and 210c that are displayed in a variation animation within the variation animation of the pseudo-continuous reach variation pattern until the reach development animation begins. For example, "Pseudo 2a" is a pseudo-continuous reach variation pattern of "Pseudo 2" in which the animation symbols 210a, 210b, and 210c are displayed in a variation animation twice, and indicates that the main variation animation image is display pattern a. Also, "Pseudo 3b" is a pseudo-continuous reach variation pattern of "Pseudo 3" in which the animation symbols 210a, 210b, and 210c are displayed in a variation animation three times, and indicates that the main variation animation image is display pattern b.

[0517] Furthermore, in the first half and second half variation performance determination tables shown in Figure 58, the selection ratios for the no-reach variation pattern and the normal reach variation pattern are set so that they are executed only when the result of the big win lottery is a miss. In addition, the development reach variation pattern and the pseudo-continuous reach variation pattern are determined both when there is a miss and when there is a big win, but the development reach variation pattern has a higher selection ratio when there is a miss and a lower selection ratio when there is a big win than the pseudo-continuous reach variation pattern. By setting the selection ratios in this way for both misses and big wins, the pseudo-continuous reach variation pattern is set to have a higher reliability than the development reach variation pattern.

[0518] Furthermore, within the pseudo-consecutive reach variation patterns, the more pseudo-reels there are, the higher the selection rate for a big win and the lower the selection rate for a loss. The settings are designed so that the more pseudo-reels there are, the higher the reliability.

[0519] As described above, the general flow of the variable performance is determined by the variable performance determination table, but at the start of the variable performance, the feasibility and execution pattern of various elemental performances that constitute the variable performance are further determined based on the variable mode command or variable pattern command. Here, elemental performances refer to all performances that constitute the variable performance, such as the variable display of performance symbols 210a, 210b, and 210c in the main performance display unit 200a, the development image displayed in the main performance display unit 200a during the reach development performance, and the performance that moves the performance mechanism device 202.

[0520] Figure 59 is the first diagram illustrating an example of a timer effect according to this embodiment. The timer effect indicates in advance that some element effect will be executed during the fluctuation effect. Multiple elements are provided for the element effect to be executed during the fluctuation effect, which are pre-set as target candidates. The timer effect targets one of these multiple target candidates and is executed before the start of the target candidate.

[0521] In this embodiment, in order to update the image of the main display unit 200a at a rate of 30 frames per second, the timer interrupt process is performed 30 times per second, or approximately once every 0.033 seconds.

[0522] For example, at the start of the timer effect, an animation of the first timer display unit 222a appearing is played in the lower left of the main effect display unit 200a, as shown in Figure 59(a). In this appearance animation, for example, the shutter image displayed when the first timer display unit 222a appears gradually opens over 30 frames, or 1 second. At the end of the appearance animation, the timer value (initial time information) "5.00" is displayed on the first timer display unit 222a, as shown in Figure 59(b), and thereafter, as time progresses, the timer value is updated (subtracted) as shown in Figures 59(c) and (d). In this embodiment, the initial time information consists of an integer part ("5" in Figure 59(b)) and a decimal part ("00" in Figure 59(b)).

[0523] Then, as shown in Figure 59(e), when the timer value on the first timer display unit 222a becomes "0.00", "GOGO" is displayed on the first timer display unit 222a immediately afterward, indicating that the target performance will be executed. In this embodiment, the "GOGO" display on the first timer display unit 222a is displayed for 30 frames, or 1 second. Then, 30 frames, or 1 second, elapses after the "GOGO" display ends, and the target performance is executed.

[0524] Thus, the timer effect suggests that some kind of elemental effect will be executed afterward, and it counts down the remaining time until the target is reached. Because the player cannot see what elemental effect will be executed during the timer effect, it can create a sense of anticipation that an elemental effect with a high probability of leading to a jackpot will be executed.

[0525] In this embodiment, the case where the timer effect starts during a fluctuation effect in which the target candidate is executed (hereinafter referred to as the "target fluctuation effect") is described, but the timer effect may start before the start of the target fluctuation effect.

[0526] Figure 60 is a second diagram illustrating an example of timer effects according to this embodiment. As shown in Figure 60, in this embodiment, it is possible to execute (display) up to three timer effects (first timer display unit 222a, second timer display unit 222b, and third timer display unit 222c) simultaneously.

[0527] Furthermore, as shown in Figure 60, if the timer value displayed in the timer display unit (third timer display unit 222c) is greater than 99.99 seconds, an image with the words "Preparing" will be displayed instead of the timer value.

[0528] Figure 61 is a diagram illustrating potential targets for the timer effect according to this embodiment. As described above, various elemental effects are executed in a single fluctuation effect, but potential targets for the timer effect are predetermined, and the target is selected from among these candidates.

[0529] As shown in Figures 61(a) and (b), among the elemental effects that serve as turning points in the fluctuation effect, target candidates Ta1 to Ta8 are provided as elemental effects that can be targeted by the timer effect. These target candidates Ta1 to Ta8 are elemental effects that are located at fluctuation divisions that serve as turning points in the flow of the effect within a single fluctuation effect, and their appearance or non-appearance is mainly determined by the fluctuation effect determination table. Specifically, target candidates Ta1 to Ta3 are the temporary stop display in the 1st to 3rd pseudo-modes of the effect symbols 210a, 210b, and 210c, respectively; target candidate Ta4 is the effect when a reach is displayed; target candidate Ta5 is the first reach development effect; target candidate Ta6 is the reach-up effect; target candidate Ta7 is the second reach development effect; and Ta8 is the judgment effect.

[0530] Therefore, for example, if target candidate Ta3 is determined to be the target, the timer display unit (e.g., first timer display unit 222a) will start updating the timer value a predetermined time before the temporary stop display in the third pseudo-mode of the performance symbols 210a, 210b, and 210c, and "GOGO" will be displayed on the timer display unit (e.g., first timer display unit 222a) immediately before the temporary stop display in the third pseudo-mode.

[0531] Similarly, for example, if candidate Ta7 is selected as the target, the timer display unit (e.g., the first timer display unit 222a) will start updating the timer value from a predetermined time before the start of the second reach development sequence, and "GOGO" will be displayed on the timer display unit (e.g., the first timer display unit 222a) immediately before the start of the second reach development sequence.

[0532] Figure 62 illustrates the timer effect execution decision table. Whether or not the timer effect is executed is determined by referring to the timer effect execution decision table. According to the timer effect execution decision table, as shown in Figure 62, for each combination of variation mode number and variation pattern number (variation information), the selection ratio for executing the timer effect (once, twice, or three times) and not executing it is set. Here, the more likely a variation information is to determine a variation effect execution pattern with a high reliability, the higher the probability that the timer effect will be executed. In other words, the timer effect itself is a highly reliable effect.

[0533] In this embodiment, when the sub-control board 330 receives a fluctuation command, it refers to the timer effect execution decision table to determine whether or not to execute the timer effect.

[0534] If a decision is made to execute the timer effect (once, twice, or three times), the target determination table is referenced to determine the candidate target T for the timer effect.

[0535] Figure 63 illustrates an example of a timer effect target determination table (single execution) according to this embodiment. Specifically, a target determination table is provided for each number of timer effect executions, and when the timer effect is executed once, the target candidate T to be used for the timer effect is determined by referring to the timer effect target determination table (single execution) shown in Figure 63.

[0536] Furthermore, if the timer effect is executed twice, the target candidate T for the first timer effect (first timer display unit 222a) and the target candidate T for the second timer effect (second timer display unit 222b) are determined by referring to a timer effect target determination table (not shown) for cases where the timer effect is executed twice.

[0537] Furthermore, if the timer effect is executed twice, the selection ratio is set so that the target candidate T for the second timer effect (second timer display unit 222b) is selected at a later timing than the target candidate T for the first timer effect (first timer display unit 222a).

[0538] Similarly, if the timer effect is executed three times, the target candidate T for the first timer effect (first timer display unit 222a), the target candidate T for the second timer effect (second timer display unit 222b), and the target candidate T for the third timer effect (third timer display unit 222c) are determined by referring to a timer effect target determination table (not shown) for cases where the timer effect is executed three times.

[0539] Furthermore, when the timer effect is executed three times, the selection ratio is set so that the target candidate T for the second timer effect (second timer display unit 222b) is selected at a later timing than the target candidate T for the first timer effect (first timer display unit 222a). In addition, the selection ratio is set so that the target candidate T for the third timer effect (third timer display unit 222c) is selected at a later timing than the target candidate T for the second timer effect (second timer display unit 222b).

[0540] As described above, once the execution of the timer effect is decided and the target of the timer effect is determined, the appearance timing of the timer display units (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c) is then determined.

[0541] In this embodiment, in order to suppress deterioration of appearance, the timing of appearance is determined such that the value initially displayed on the timer display unit (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c), that is, the decimal part of the initial time information, is basically "00", and the integer part of the initial time information is one of a plurality of predetermined types. For example, 116 types of integer parts of the initial time information are provided, ranging from "120" to "5".

[0542] Then, based on the start time of the target candidate T, the execution pattern of the target variation effect (variation command), etc., first, select an integer value of the selectable initial time information. After selecting an integer value of the selectable initial time information, refer to the appearance timing determination table (not shown) and decide on one of the selected integer values ​​of the initial time information.

[0543] As described above, the appearance operation requires 30 frames, the display of "GOGO" requires 30 frames, and 30 frames are required from the end of the "GOGO" display until the target is executed. Therefore, for example, if the integer part of the determined initial time information is "13", the appearance timing of the timer display unit (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c) is determined to be 480 frames before the timing when the target is executed.

[0544] In this embodiment, when the timer effect is executed twice, the selection ratio in the appearance timing determination table (not shown) is set so that the appearance timing of the second timer effect (second timer display unit 222b) is set later than that of the first timer effect (first timer display unit 222a).

[0545] Furthermore, when the timer effect is executed three times, the selection ratio in the appearance timing determination table (not shown) is set so that the appearance timing of the second timer effect (second timer display unit 222b) is set later than that of the first timer effect (first timer display unit 222a), and the appearance timing of the third timer effect (third timer display unit 222c) is set later than that of the second timer effect.

[0546] In other words, in this embodiment, the selection ratio in the appearance timing determination table (not shown) is set so that the appearance timings of the first timer display unit 222a, the second timer display unit 222b, and the third timer display unit 222c are different.

[0547] However, the selection ratio in the appearance timing determination table (not shown) may be set so that at least two of the appearance timings of the first timer display unit 222a, the second timer display unit 222b, and the third timer display unit 222c can be determined to be the same appearance timing.

[0548] However, multiple appearance timings for the timer display unit (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c) may be set in advance. For example, the following may be set in advance as appearance timings: at the start of the target variation performance in which the target candidate T determined as the target is executed (SP1), at the second variation display (re-variation display) of the performance symbols 210a, 210b, 210c in the target variation performance (SP2), at the third variation display (re-variation display) of the performance symbols 210a, 210b, 210c in the target variation performance (SP3), at the fourth variation display (re-variation display) of the performance symbols 210a, 210b, 210c in the target variation performance (SP4), and at the time of the reach display in the target variation performance (SP5).

[0549] Furthermore, the appearance timing of the timer display units (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c) may be determined to be one of the five appearance timings described above. Specifically, for example, based on the start time of the target candidate T determined as the target and the execution pattern (variation command) of the target variation effect, all appearance timings that exist before the target candidate T determined as the target are first selected. Then, after selecting the appearance timings that exist before the target candidate T determined as the target, the appearance timing determination table (not shown) is referred to and one of the selected appearance timings is determined as the appearance timing. In this case, the appearance timing may be adjusted based on the determined appearance timing so that the decimal part of the initial time information becomes "00".

[0550] Figure 64 illustrates the method for deriving initial time information. Figure 64(a) shows the case where no delays occur in the various processes. As shown in Figure 64(a), when no delays occur in the various processes, the initial time information determination process for deriving the initial time information is executed when the occurrence point determined as described above is reached.

[0551] Specifically, in the initial time information determination process, the time from the current moment, i.e., the appearance point, until the target is executed is first derived. In the case shown in Figure 64(a), it is derived that the time from the appearance point until the target is executed is 480F. As described above, the appearance operation requires 30F, the display of "GOGO" requires 30F, and it takes 30F from the end of the "GOGO" display until the target is executed. Therefore, the period during which the timer value can be updated and displayed (subtracted) is derived to be 390F. As described above, the sub-control board 330 updates the image of the main performance display unit 200a at 30F (frames) per second, so the initial time information is derived to be "13.00" seconds. As described above, in this embodiment, the appearance timing is set so that the decimal part of the initial time information is basically "00".

[0552] Incidentally, unforeseen circumstances such as delays in various processes can occur in gaming machines. Figure 64(b) shows what happens when delays occur in various processes. When a delay occurs, the execution timing of the initial time information determination process may be delayed from the originally planned timing (appearance timing). Figure 64(b) shows what happens when the execution timing of the initial time information determination process is delayed by 3 frames from the originally planned timing (appearance timing). In this case, in this embodiment, a correction process is executed in the initial time information determination process to correct the start timing of the appearance operation and the value of the initial time information.

[0553] Specifically, in the correction process, the time from the current moment until the target is executed is first derived. In the case shown in Figure 64(b), the execution timing of the initial time information determination process occurs 3 frames after the appearance timing, so it is derived that the time from the current moment until the target is executed is 477 frames. As described above, the appearance operation takes 30 frames, the display of "GOGO" takes 30 frames, and it takes 30 frames from the end of the "GOGO" display until the target is executed. Therefore, the period during which the timer value can be updated and displayed (subtracted) is derived to be 387 frames. In this embodiment, in order to suppress deterioration of appearance, when the correction process is executed, the period during which the timer value is updated and displayed (subtracted) is corrected so that the decimal part of the initial time information becomes "00" or "50". Specifically, in the case shown in Figure 64(b), 387 frames is divided by 15 frames (0.5 seconds) and the quotient and remainder are derived. In the case shown in Figure 64(b), the quotient is 25 and the remainder is 12F.

[0554] Then, the quotient value (in this case, 25) is multiplied by 0.5 seconds to obtain a value of 25 × 0.5 = 12.50 seconds, which is set as the initial time information. In other words, in this case, the integer part of the initial time information will be "12", and the decimal part of the initial time information will be "50".

[0555] Furthermore, the start timing of the appearance animation is determined based on the remainder (in this case, 12F). In other words, in this case, the start timing of the appearance animation is set to 12F (0.4 seconds) after the correction process is executed. In other words, as a result of the correction process, the start timing of the appearance animation will be delayed by 15F compared to when no delay occurs. In other words, the execution timing of the appearance animation should be delayed until the difference in time between the initial time information when the correction process is not performed and the initial time information when the correction process is performed (in this case, 15F) has elapsed.

[0556] As a result of the above correction process, as shown in Figure 64(b), the appearance action is executed 15 frames after the original appearance timing, and the timer value is updated and displayed from "12.50" 45 frames after the original appearance timing. When the timer value becomes "00.00", "GOGO" is displayed on the timer display unit (first timer display unit 222a) for 30 frames, and 30 frames, or 1 second, after the "GOGO" display ends, the target effect is executed. This makes it possible to suppress the possibility that the timing at which the countdown time in the timer effect reaches 0 will deviate from the originally planned timing, even if unforeseen circumstances such as delays in various processes occur, thereby suppressing the possibility of a decrease in the effect of the effect.

[0557] Next, we will explain the processing in the sub-control board 330 for executing the timer effect described above. Note that in the following explanation, we will omit the explanation of the processing in the sub-control board 330 that is not related to the timer effect described above.

[0558] (Sub-CPU initialization process of sub-control board 330) Figure 65 is a flowchart illustrating the sub-CPU initialization process (S1000) of the sub-control board 330 according to this embodiment.

[0559] (Step S1000-1) When power is turned on, the sub-CPU 330a reads the CPU initialization program from the sub-ROM 330b and performs initialization and setting processes for flags and other items stored in the sub-RAM 330c.

[0560] (Step S1000-3) Next, the sub-CPU 330a performs the process of updating each random number for the animation, and thereafter repeats the process of step S1000-3 until an interrupt is processed. Note that there are multiple types of random numbers for the animation, and each random number for the animation is updated asynchronously.

[0561] (Sub-timer interrupt processing on sub-control board 330) Figure 66 is a flowchart illustrating the sub-timer interrupt processing (S1100) of the sub-control board 330 according to this embodiment. The sub-control board 330 is provided with a reset clock pulse generation circuit (not shown) that generates clock pulses at a predetermined period (30 times per second). Upon generation of clock pulses by this reset clock pulse generation circuit, the sub-CPU 330a reads the timer interrupt processing program and starts the sub-timer interrupt processing.

[0562] (Step S1100-1) Sub-CPU 330a saves the registers.

[0563] (Step S1100-3) Sub-CPU 330a performs the processing required to enable interrupts.

[0564] (Step S1100-5) The sub-CPU 330a performs update processing for various timer counters used by the sub-control board 330. Here, unless otherwise specified, the timer counters are decremented by 1 each time the sub-timer interrupt processing of the sub-control board 330 occurs, and the decrementing stops when they reach 0.

[0565] (Step S1200) The sub-CPU 330a analyzes the commands stored in the receive buffer of the sub-RAM 330c and executes sub-main processing that performs various operations according to the received commands. When a command is sent from the main control board 300 to the sub-control board 330, a command reception interrupt is performed, and the command sent from the main control board 300 is stored in the receive buffer. Here, the command stored in the receive buffer by the command reception interrupt is analyzed.

[0566] (Step S1300) Act unit 340 performs the main act unit processing, which will be described in more detail later.

[0567] (Step S1100-7) Sub-CPU 330a restores the registers and terminates the sub-timer interrupt processing.

[0568] The sub-control board 330 is provided with an operation buffer, and the output timing is pre-set for each message set in the operation buffer. When the execution of the variation effect begins, the effect execution program corresponding to the execution pattern of the first half variation effect or the execution pattern of the second half variation effect is started, and the act unit 340 sequentially acquires the messages stored in the operation buffer according to the elapsed time from the start of the variation effect (or the elapsed time from the start of the second half variation effect), and outputs the acquired messages to the display control unit 350. The messages output to the display control unit 350 are then erased from the operation buffer.

[0569] Figure 67 is a flowchart illustrating the sub-main processing in the sub-control board 330 according to this embodiment.

[0570] (Step S1210-1) The sub-CPU 330a determines whether a variation command has been received. The variation command is set in the main control board 300 during the special symbol variation number determination process, and then transmitted to the sub-control board 330 by the sub-command transmission process. If it is determined that a variation command has been received, the process moves to step S1210-3; if it is determined that no variation command has been received, the sub-main process ends.

[0571] (Step S1210-3) SubCPU 330a analyzes the received variation mode command, refers to the first half variation effect determination table to determine the execution pattern for the first half variation effect, and sets a message for the execution pattern of the first half variation effect in the operation buffer based on the determined execution pattern of the first half variation effect.

[0572] (Step S1210-5) SubCPU 330a analyzes the received variation pattern command, refers to the second half variation effect determination table to determine the execution pattern for the second half variation effect, and sets a message for the second half variation effect execution pattern in the operation buffer based on the determined execution pattern. SubCPU 330a also sets the effect execution program corresponding to the second half variation effect execution pattern to the effect execution program for the second half variation effect that is scheduled to be started.

[0573] (Step S1210-7) The sub-CPU 330a, based on the received variable mode command and variable pattern command, refers to various notification determination tables, determines the execution pattern for various notification effects, and sets a message based on the determined execution pattern for the notification effect in the operation buffer.

[0574] Specifically, for example, the timer effect execution decision table (Figure 62) is referenced to determine the timer effect execution pattern (whether or not to execute, and the number of times to execute if executed). Then, if the execution of the timer effect is decided, the timer effect target decision table (Figure 63) corresponding to the number of executions is referenced to determine the target for each timer effect. Furthermore, the start timing of each timer effect execution is determined.

[0575] As described above, in this embodiment, the earlier the target timer effect is executed, the earlier its execution start timing is determined. Once the execution start timing for each timer effect is determined, a message indicating the start of the timer effect (timer effect execution start message) is set in the operation buffer based on the determined execution pattern.

[0576] The message indicating the start of a timer effect includes information such as the type of timer effect to be started (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c), the start timing of the timer effect to be started (more specifically, the appearance action) (number of frames from the start of the change), and the target execution timing (number of frames from the start of the change).

[0577] Figure 68 is a flowchart illustrating the main processing of the act section in the sub-control board 330 according to this embodiment.

[0578] (Step S1300-1) Act Unit 340 determines whether it is the start of the second half variation effect. If it is determined that it is the start of the second half variation effect, the process moves to step S1300-3; if it is determined that it is not the start of the second half variation effect, the process moves to step S1300-5.

[0579] (Step S1300-3) Act Unit 340 starts the performance execution program for the second half variation effect. Here, it starts the performance execution program corresponding to the performance execution pattern for the second half variation effect determined in step S1210-5 above.

[0580] (Step S1300-5) The act unit 340 adds the counter value of the variable time timing timer and updates the execution time of the variable effect.

[0581] (Step S1300-7) The act unit 340 determines whether the timing for outputting the execution start message of any of the timer effects (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c) has been reached. If the timing for outputting the execution start message of any of the timer effects (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c) has been reached, the process moves to step S1310. If the timing for outputting the execution start message of any of the timer effects (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c) has not been reached, the process moves to step S1320.

[0582] (Step S1310) The act unit 340 executes the timer effect control process (start), which will be described in detail later. Specifically, the timer effect control process (start) is executed only once for each timer effect (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c) when the timing for outputting the execution start message is reached.

[0583] (Step S1320) Act unit 340 executes timer effect control processing (after start), which will be described in detail later.

[0584] (Step S1300-9) When it is time for the output of various messages other than the timer effect start message, the act unit 340 retrieves the message set in the operation buffer, outputs the retrieved message to each effect device, and starts the execution of the preview effect.

[0585] Figure 69 is a flowchart illustrating the timer effect control process (at startup) in the sub-control board 330 according to this embodiment.

[0586] (Step S1310-1) The act unit 340 determines whether the current timing is delayed for the timer display (first timer display unit 222a, second timer display unit 222b, or third timer display unit 222c) that has reached the output timing. Specifically, for example, the act unit 340 determines that a delay has occurred if the counter value of the variable time timing timer updated in step S1300-5, i.e., the number of frames elapsed since the start of the variation, is larger than the execution start timing (number of frames since the start of variation) included in the execution start message that has reached the output timing. The act unit 340 also determines that no delay has occurred if the execution start timing (number of frames since the start of variation) included in the execution start message that has reached the output timing is equal to the counter value of the variable time timing timer updated in step S1300-5, i.e., the number of frames elapsed since the start of the variation.

[0587] (Step S1310-3) Act Unit 340 performs an initial time information determination process (without delay) to derive initial time information based on the set timer effect execution start message. Specifically, Act Unit 340 derives the time from the current moment, i.e., the appearance timing, until the target is executed. Then, Act Unit 340 derives a value obtained by subtracting 90F from the time from the appearance timing until the target is executed, and sets this derived value as the initial time information.

[0588] (Step S1310-5) The Act Unit 340 outputs an appearance start message to each performance device to immediately begin the execution of the appearance operation. This message includes information such as the type of timer performance to be started (first timer display unit 222a, second timer display unit 222b, or third timer display unit 222c), initial time information, and target execution timing.

[0589] (Step S1310-7) The act unit 340 reserves the output of a subtraction start message to each effect device to start updating (subtracting) the timer value from the initial time information after 30 frames for the timer effect whose appearance operation was started in step S1310-5, and then terminates the timer effect control processing (start). As a result, the update and display (subtraction display) of the timer value will start 30 frames after the start of the appearance operation.

[0590] (Step S1312) Act unit 340 performs a correction process, which will be described in detail later, and then terminates the timer performance control process (at the start).

[0591] Figure 70 is a flowchart illustrating the correction process in the sub-control board 330 according to this embodiment.

[0592] (Step S1312-1) Act Unit 340 executes an initial time information determination process (delay occurrence) to derive initial time information corrected based on the set timer effect execution start message and the delay time that occurred. Specifically, Act Unit 340 derives the time from the current time, i.e., the time when the correction process is executed at the time the delay occurs, until the target is executed. Then, Act Unit 340 derives a value obtained by subtracting 90F from the time from the current time until the target is executed, divides the derived value by 15F (0.5 seconds), and derives the quotient and remainder. Act Unit 340 sets the value obtained by multiplying the derived quotient by 0.5 seconds as the initial time information. In this case, as described above, the decimal part of the initial time information will be "00" or "50".

[0593] (Step S1312-3) The act unit 340 determines the start timing of the appearance operation based on the remainder value derived in step S1312-1. Specifically, the act unit 340 determines the start timing of the appearance operation to be after the remainder value (number of frames) derived in step S1312-1, after the correction process has been executed. In other words, as a result of the correction process, the start timing of the appearance operation will be delayed by 15 frames compared to when no delay occurs.

[0594] (Step S1312-5) The act unit 340 reserves the output of an appearance start message to each performance device at the execution start timing determined in step S1312-3 above, in order to start the appearance operation.

[0595] (Step S1312-7) The act unit 340 reserves the output of a subtraction start message to each performance device to start updating (subtracting) the timer value from the initial time information 30F after the execution timing determined in step S1312-3, and then terminates the correction process.

[0596] Figure 71 is a flowchart illustrating the timer effect control process (after start) in the sub-control board 330 according to this embodiment.

[0597] (Step S1320-1) The act unit 340 determines whether the timing for outputting the subtraction start message, which was reserved in step S1310-7 or step S1312-7, has been reached. If the timing for outputting the subtraction start message has been reached, the process moves to step S1320-3; otherwise, the process moves to step S1320-5.

[0598] (Step S1320-3) The act unit 340 outputs a message to each performance device indicating that the output timing has been reached, indicating the start of the subtraction process.

[0599] (Step S1320-5) The act unit 340 determines whether or not there is a timer effect in which the timer value is being updated (subtracted). If there is a timer effect in which the timer value is being updated (subtracted), the process moves to step S1320-7. If there is no timer effect in which the timer value is being updated (subtracted), the timer effect control process (after start) is terminated.

[0600] (Step S1320-7) Act Unit 340 performs a subtraction display process to perform an update display (subtraction display) of the timer value. Specifically, when the above correction process is performed and the decimal part of the initial time information is "50", Act Unit 340 outputs a fractional subtraction message to each performance device to subtract the decimal part from "50" to "00". Then, after 15 frames, that is, when the decimal part becomes "00" due to the update display (subtraction display) of the timer value, Act Unit 340 outputs an integer part subtraction message to subtract "1" from the integer part, and a decimal part subtraction message to subtract the decimal part from "99" to "00", to each performance device. Thereafter, Act Unit 340 outputs an integer part subtraction message and a decimal part subtraction message to each performance device every 30 frames.

[0601] Furthermore, if the above correction process is performed and the decimal part of the initial time information is "00", and if the above correction process is not performed, the act unit 340 outputs an integer part subtraction message and a decimal part subtraction message to each performance device every 30 frames.

[0602] (Step S1320-9) The act unit 340 determines whether the time set in the initial time information has elapsed since the timer value update display (subtraction display) started and whether the timing to start displaying "GOGO" has been reached. If the timing to start displaying "GOGO" has been reached, the process moves to step S1320-11; if the timing to start displaying "GOGO" has not been reached, the timer effect control process (after start) is terminated.

[0603] (Step S1320-11) The act unit 340 outputs a GOGO display start message to each performance device to initiate the "GOGO" display, and then terminates the timer performance control process (after start).

[0604] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but it goes without saying that the present invention is not limited to these embodiments. It will be obvious to those skilled in the art that various modifications or alterations can be conceived within the scope of the claims, and these will naturally also fall within the technical scope of the present invention.

[0605] In the above embodiment, an example of when the present invention is applied to a Type I gaming machine was described, but the gameplay of gaming machines 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 Type II gaming machines and Type I and Type II mixed machines. In other words, the gameplay of gaming machines to which the present invention can be applied is not particularly limited.

[0606] In any case, the present invention is widely applicable to the following gaming machines. A target determination means (in the above embodiment, as an example, a sub-CPU 330a that performs processing in step S1210-7) that determines one of several target effects as the target effect, A predetermined performance execution means (an act unit 340 that executes processing in steps S1310-5 and S1312-5, for example) that executes a predetermined performance (an animation of appearance in the above embodiment, for example) that displays a time display unit (in the above embodiment, for example, a first timer display unit 222a, a second timer display unit 222b, and a third timer display unit 222c) on a performance display unit (in the above embodiment, for example, a main performance display unit 200a), An initial time information derivation means (in the above embodiment, as an example, an act unit 340 that performs processing in steps S1310-3 and S1312-1) that derives initial time information that indicates the time from a predetermined timing to the execution of the target performance, A time information update means (in the above embodiment, an act unit 340 that performs processing in steps S1310-7 and S1312-7) that displays initial time information on the time display unit and updates the time display unit as time progresses, Equipped with, The predetermined performance execution means is, A gaming machine that performs a correction process to delay the execution timing of a predetermined performance (in the above embodiment, as an example, an act unit 340 that performs the process in step S1312).

[0607] Furthermore, the initial time information may include both an integer and a decimal part. Furthermore, the initial time information derivation means may derive initial time information in which the decimal part is a predetermined value (for example, "00" in the above embodiment) if no correction process is performed, and may derive specific initial time information in which the initial time information is shorter than in the case where no correction process is performed, and the decimal part is a specific value different from the predetermined value (for example, "50" in the above embodiment).

[0608] Furthermore, the predetermined performance execution means may delay the execution timing of the predetermined performance by correction processing until the time difference between the initial time information in the case where the correction processing is not performed and the specific initial time information has elapsed.

[0609] In the above embodiment, the case where the correction process is performed so that the decimal part of the initial time information is "00" or "50" is shown. However, the possible values ​​for the decimal part of the initial time information may or may not be predetermined. If the possible values ​​for the decimal part of the initial time information are not predetermined, for example, if the execution timing of the initial time information determination process is delayed by 3 frames from the originally planned timing (appearance timing), the value of the initial time information can be corrected to "12.90" without changing the start timing of the appearance operation.

[0610] Furthermore, in the above embodiment, a correction process is performed to change the value of the initial time information when a delay occurs. However, when a delay occurs, the execution time of the appearance action may be changed as a correction process. In this case, multiple animations of appearance actions with different execution times may be provided in advance, or the animation of the appearance action may be fast-forwarded according to the execution time.

[0611] Furthermore, both a correction process that modifies the value of the initial time information and a correction process that modifies the execution time of the appearance action may be performed. For example, if a delay exceeding 15F occurs (e.g., a delay of 20F), the correction process that modifies the value of the initial time information may shorten the value of the initial time information by 0.5 seconds, or 15F, and the correction process that modifies the execution time of the appearance action may shorten the execution time of the appearance action by 5F.

[0612] Furthermore, if a predetermined condition is met, a correction process may be executed to change the value of the initial time information, and if the predetermined condition is not met, a correction process may be executed to change the execution time of the appearance operation. For example, if the value of the initial time information derived when no delay occurs is greater than or equal to a predetermined value (e.g., 5.00 seconds or more), the predetermined condition may be met, and if the value of the initial time information derived when no delay occurs is less than a predetermined value (e.g., less than 5.00 seconds), the predetermined condition may not be met. This makes it possible to suppress the risk that the value initially displayed in the timer display unit (first timer display unit 222a, second timer display unit 222b, third timer display unit 222c) will become too small due to the correction process, that is, the period during which the timer value in the timer effect is updated and displayed (subtracted and displayed) will become too short, which may reduce the effect of the effect.
