Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the gaming machine described in Patent Document 1 above, there remained room for improvement regarding the control of the gaming machine when a communication abnormality occurred between the main control board and the frame control board.

[0005] In view of the above problems, an object of the present invention is to provide a gaming machine that can perform appropriate control when a communication abnormality occurs between a main control board and a frame control board in an enclosed gaming machine.

Means for Solving the Problems

[0006] To solve the above problems, the present invention includes a main control means for controlling the transition of game states including a first game state, a second game state, and a specific game state in which control related to auxiliary games is more advantageous than the first game state and the second game state, a virtual game medium number control means for performing processing related to subtraction and addition of the number of playable virtual game media and displaying the number of virtual game media on a game medium number display, and a game effect means capable of executing a game mode effect according to the game state. The notification mode of a predetermined notification means can be changed according to the number of virtual game media displayed on the game medium number display. The main control means can generate a game machine information notification command including information indicating the game state and transmit it to the virtual game medium control means. When the virtual game medium control means receives the game machine information notification command, it can transmit a response command to the main control means. When the main control means determines that a situation where the response command cannot be received has occurred continuously for a predetermined number of times, it determines that a communication failure has occurred, and after transmitting a communication failure occurrence command to the game effect means, it can execute a standby process. This is the gist of the invention.

Effect of the Invention

[0007] According to the present invention, in an enclosed game machine, appropriate control can be performed when a communication abnormality occurs between the main control board and the frame control board.

Modes for Carrying Out the Invention

[0009] <First Embodiment> Hereinafter, a first embodiment of the present invention will be specifically described with reference to the drawings.

[0010] (Overview of the gaming machine 1) Unlike well-known pachinko gaming machines, the gaming machine 1 does not use a gaming ball supply mechanism or a gaming ball discharge mechanism for island facilities. It accommodates a predetermined number of gaming balls, conducts games by launching the accommodated gaming balls into the gaming area, collects the gaming balls that have finished the games, and conducts games again by launching the collected gaming balls. It is an enclosed gaming machine.

[0011] (Basic configuration of the gaming machine 1) First, with reference to FIGS. 1 to 4, the basic configuration of the gaming machine 1 will be described. FIG. 1 is a front view of the gaming machine 1 and the card unit 9 of the present invention. FIG. 2 is an enlarged view of the second large winning opening 17 of the gaming machine 1. FIG. 3 is a perspective view of the back side of the gaming machine 1 and the card unit 9. FIG. 4 is a view showing the main control board 110 and the frame control board 160 on the back of the gaming machine 1, and the covers 110c and 160c covering them.

[0012] As shown in FIGS. 1 and 3, the gaming machine 1 includes an outer frame 60 and a glass frame 50 that is rotatably supported. The outer frame 60 is provided with a game board 2 having a gaming area 6 where gaming balls flow down. The gaming area 6 has a left area 6L on the left side of the center and a right area 6R on the right side of the center.

[0013] One end of the glass frame 50 is connected to the outer frame 60 via a hinge mechanism portion 51, and a lock mechanism is provided at the other end of the glass frame 50. The lock mechanism of the glass frame 50 can be unlocked with a dedicated key, and by unlocking, it can be swung by the hinge mechanism portion 51 to open the gaming area 6. A door opening detection SW81c (not shown) is provided on the glass frame 50.

[0014] The glass frame 50 is provided with a production button 35 that can be pressed. The production button 35 is provided with a production button detection SW 35a. When the production button detection SW 35a detects the operation of the production button 35 by the player, it outputs predetermined information to the gaming machine 1. Therefore, the player can input predetermined information to the gaming machine 1 by operating the production button 35.

[0015] On the left side of the production button 35, a cross key 39 that can be pressed is provided. The cross key 39 is provided with an up cursor key 39A, a left cursor key 39B, a down cursor key 39C, a right cursor key 39D, and a center cursor key 39E. Each of them is provided with a cross key detection SW 39a, a cross key detection SW 39b, a cross key detection SW 39c, a cross key detection SW 39d, and a cross key detection SW 39e. When each cross key detection SW detects the operation of the cross key 39 by the player, it outputs predetermined information to the gaming machine 1. Therefore, the player can input predetermined information to the gaming machine 1 by operating the cross key 39.

[0016] The glass frame 50 is provided with an operation handle 3 that fires a game ball into the game area 6 by a rotation operation. The operation handle 3 is provided with a touch sensor 3a. The touch sensor 3a detects that the player is touching the operation handle 3. When the player rotates the operation handle 3, the firing volume 3b provided in the vicinity of the operation handle 3 also rotates, and the hitting member directly connected to the firing solenoid 4a rotates with a firing intensity corresponding to the rotation amount of the firing volume 3b.

[0017] The ball feed solenoid 4b provided in the vicinity of the operation handle 3 sends out the game balls stored in the gaming machine 1 one by one to the hitting member directly connected to the firing solenoid 4a. These touch sensor 3a, firing volume 3b, firing solenoid 4a, and ball feed solenoid 4b perform operations related to the above-mentioned firing operation under the control of the firing control unit 170 in the frame control board 160.

[0018] The game balls sent out to the hitting member are hit between the rail 5a and the rail 5b by the rotation of the hitting member, pass through the ball return prevention member 5c, and enter the game area 6. Between the rail 5a and the rail 5b, a fired ball sensor 2a, a foul ball sensor 2b, a small ball sensor 81a, and an iron ball sensor 81b are provided (all not shown in the figure).

[0019] When the fired ball sensor 2a detects that the game ball hit between the rails 5a and 5b has exceeded the firing detection point at the upper end of the rail 5b, it outputs a firing signal. When the foul ball sensor 2b detects that the game ball hit between the rails 5a and 5b has returned without reaching the game area 6, it outputs a foul signal. When the small ball sensor 81a detects that a small ball has been hit between the rails 5a and 5b, it outputs a small ball detection signal. When the iron ball sensor 81b detects that an iron ball has been hit between the rails 5a and 5b, it outputs an iron ball detection signal.

[0020] On the glass frame 50, audio output devices 32 which are speakers are provided on the left and right. The audio output devices 32 perform effects such as music and sound effects according to the progress of the game. Near the two audio output devices 32, a fourth effect lighting device 340d and two fifth effect lighting devices 340e are provided. The fourth effect lighting device 340d and the fifth effect lighting device 340e respectively have a fourth lamp 34d and a fifth lamp 34e which are full-color LEDs. The fourth effect lighting device 340d and the fifth effect lighting device 340e perform the light emission operations of the fourth lamp 34d and the fifth lamp 34e under the control of the lamp / drive control unit 150 of the effect control board 120 to perform game effects.

[0021] Inside the game area 6 of the game board 2, a general winning opening 12, a normal symbol gate 13, a first start opening 14, a second start opening 15, a first big winning opening 16, a second big winning opening 17, and an image display device 31 are provided.

[0022] Three general winning openings 12 are provided below the game area 6L. A general winning opening detection SW12a is provided for the general winning opening 12. When the winning of a game ball into the general winning opening 12 is detected by the general winning opening detection SW12a, a predetermined number of game balls are given to the player.

[0023] A first start opening 14 is provided at the lower center of the game area 6 of the game board 2. A second start opening 15 is provided in the right part of the game area 6 of the game board 2. When a game ball is launched (hit to the left) towards the left area 6L of the game area 6, the game ball can win in the first start opening 14, but it is difficult to win in the second start opening 15. When a game ball is launched (hit to the right) towards the right area 6R of the game area 6, the game ball can win in the second start opening 15, but it is difficult to win in the first start opening 14.

[0024] A first start opening detection SW14a is provided for the first start opening 14. When the winning of a game ball into the first start opening 14 is detected by the first start opening detection SW14a, a predetermined number of game balls are given to the player. A second start opening detection SW15a is provided for the second start opening 15. When the winning of a game ball into the second start opening 15 is detected by the second start opening detection SW15a, a predetermined number of game balls are given to the player. Note that the number of game balls given for the winning of a game ball into the first start opening 14 and the second start opening 15 may be the same or different. Also, although details will be described later, when the winning of a game ball into the first start opening 14 or the second start opening 15 is detected, various random values used for various processes related to the game including the jackpot lottery are acquired.

[0025] The second start port 15 is provided with two movable pieces 15b and a start port opening / closing solenoid 15c. The second start port 15 changes between two states: a closed state in which winning of a game ball is restricted by the operation of the start port opening / closing solenoid 15c, and an open state in which winning of a game ball is permitted. Specifically, the second start port 15 is controlled, by the operation of the start port opening / closing solenoid 15c, to a closed state in which the movable piece 15b becomes substantially vertical to restrict winning of a game ball, and an open state in which the movable piece 15b becomes substantially horizontal and winning of a game ball is permitted.

[0026] In addition, the second start port 15 can also vary the ease of winning of a game ball by varying the time in the open state. Although details will be described later, as the time that the second start port 15 is in the open state becomes longer, the chance of a game ball winning increases, so the ease of winning becomes higher.

[0027] An ordinary symbol gate 13 is provided at the upper right part of the game area 6 of the game board 2. The ordinary symbol gate 13 is provided with a gate detection SW 13a. When the passage of a game ball through the ordinary symbol gate 13 is detected by the gate detection SW 13a, a determination random value or the like for performing an ordinary symbol lottery described later is acquired.

[0028] A first major winning port 16 is provided in the lower right area of the game area 6 of the game board 2. The first major winning port 16 is provided with a first major winning port detection SW 16a, a first major winning port opening / closing door 16b, and a first major winning port opening / closing solenoid 16c. The first major winning port 16 changes between two states: a closed state in which winning of a game ball is restricted by the operation of the first major winning port opening / closing solenoid 16c, and an open state in which winning of a game ball is permitted.

[0029] More specifically, the first major winning port 16 becomes a closed state in which it is difficult for a game ball to win when the first major winning port opening / closing door 16b becomes substantially parallel to the surface of the game board 2 by the off operation of the first major winning port opening / closing solenoid 16c. Also, the first major winning port 16 becomes an open state in which it is easy for a game ball to win when the first major winning port opening / closing door 16b becomes substantially perpendicular to the surface of the game board 2 by the on operation of the first major winning port opening / closing solenoid 16c.

[0030] When the winning of a game ball into the first major winning opening 16 is detected by the first major winning opening detection SW16a, a predetermined number of game balls are given to the player. Note that the open state of the first major winning opening 16 changes to a closed state due to the winning of a prescribed number of game balls, which will be described later, or the elapse of a predetermined opening time.

[0031] A second major winning opening 17 is provided in the area on the right side of the game area 6 of the game board 2. The second major winning opening 17 is provided with a second major winning opening detection SW17a, a second major winning opening opening / closing door 17b, and a second major winning opening opening / closing solenoid 17c. The second major winning opening 17 changes between two states: a closed state in which the winning of a game ball is restricted by the second major winning opening opening / closing door 17b and an open state in which the winning of a game ball is permitted, by the operation of the second major winning opening opening / closing solenoid 17c.

[0032] Specifically, the second major winning opening 17 becomes a closed state in which it is difficult for a game ball to win by the off operation of the second major winning opening opening / closing solenoid 17c, causing the second major winning opening opening / closing door 17b to be substantially parallel to the surface of the game board 2. Also, the second major winning opening 17 becomes an open state in which it is easy for a game ball to win by the on operation of the second major winning opening opening / closing solenoid 17c, causing the second major winning opening opening / closing door 17b to be substantially perpendicular to the surface of the game board 2.

[0033] As shown in FIG. 2, a specific area 19B, a slide member 19C, and a second major winning opening discharge port 19E are provided inside the second major winning opening 17. The slide member 19C changes between two states: a retracted state in which it is housed deep in the gap provided in the inner wall 19 of the second major winning opening by the operation of the specific area opening / closing solenoid 18d and a forward state in which it advances in front of the gap.

[0034] Specifically, when the specific area opening / closing solenoid 18d is turned on, the slide member 19C is in the forward state, and when the specific area opening / closing solenoid 18d is turned off, the slide member 19C is in the retracted state. When the slide member 19C is in the forward state, the specific area 19B is in a closed state where it is difficult for the game balls to win, and when the slide member 19C is in the retracted state, the specific area 19B is in an open state where it is easy for the game balls to win.

[0035] Game balls passing over the specific area 19B are discharged only through the second large winning opening discharge port 19E when the slide member 19C is in the forward state, but can be discharged through the specific area 19B when the slide member 19C is in the retracted state. Game balls discharged through the second large winning opening discharge port 19E are detected by the second large winning opening detection SW17a. Game balls discharged through the specific area 19B are detected by the specific area detection SW18a. Regardless of which detection SW detects, a predetermined number of game balls are given to the player.

[0036] An out port 11 is provided at the lower center of the game area 6 of the game board 2. Game balls launched into the game area 6 are discharged from the game area 6 through the out port 11 when they do not enter any of the general winning opening 12, the first start opening 14, the second start opening 15, the first large winning opening 16, and the second large winning opening 17.

[0037] An image display device 31 is provided at the center of the game area 6. The image display device 31 displays production images according to the progress of the game, and displays waiting customer production images during the standby period when no game is being played. As the display of production images according to the progress of the game, the left symbol 36L, the middle symbol 36C, the right symbol 36R (hereinafter referred to as "decoration symbol 36"), and the fourth symbol 36Z are variably displayed according to the variable display of the special symbol. The decoration symbol 36 and the fourth symbol 36Z notify the same determination result as the big win determination result indicated by the special symbols of the first special symbol display device 20 and the second special symbol display device 21.

[0038] In addition, a radio wave detection switch SW19a (not shown) is provided at the lower center of the game area 6. When the radio wave detection switch SW19a detects a radio wave, it outputs a radio wave detection signal.

[0040] The first special symbol display device 20 is composed of 7-segment LEDs. When a game ball enters the first start port 14 of the game area 6, it performs a variable display of the special symbol and a stop display of the special symbol indicating the jackpot lottery result by lighting and extinguishing the LEDs. Similarly, the second special symbol display device 21 is composed of 7-segment LEDs. When a game ball enters the second start port 15 of the game area 6, it performs a variable display of the special symbol and a stop display of the special symbol indicating the jackpot lottery result by lighting and extinguishing the LEDs. Hereinafter, the special symbol variably displayed by the first special symbol display device 20 is referred to as the "first special symbol", and the special symbol variably displayed by the second special symbol display device 21 is referred to as the "second special symbol".

[0041] When a new variation of the first special symbol or the second special symbol cannot be started, such as during the variation of the special symbol or during the jackpot game (special game), the variable display of the special symbol is waited for under predetermined conditions. The first special symbol hold indicator 22 displays the number of variable displays that have been waited for in the first special symbol (hereinafter referred to as the "hold number"). The first special symbol hold indicator 22 is composed of two left and right LEDs, and displays the hold number of the first special symbol by their display modes. Specifically, when the hold number of the first special symbol is 1, only the left LED lights up. When the hold number of the first special symbol is 2, only the right LED lights up. When the hold number of the first special symbol is 3, the left LED blinks and the right LED lights up. When the hold number of the first special symbol is 4, both the left and right LEDs blink.

[0066] Note that communication between the main control board 110 and the frame control board 160 enables bidirectional command transmission and reception, while communication between the main control board 110 and the effect control board 120 allows command transmission only in one direction from the main control board 110 to the effect control board 120.

[0067] The main CPU 110a of the main control board 110 receives the operation clock from the crystal oscillator, reads out the game control program stored in the main ROM 110c, and performs arithmetic processing related to the game using the main RAM 110b as a work area. The main CPU 110a performs control processing according to the detection signals from each input device (such as detection switches), control processing of each output device (such as display devices), and control processing for transmitting and receiving control commands.

[0068] In the main RAM 110b of the main control board 110, various data storage areas required for game control and storage areas for storing various counters are provided, details of which will be described later. The data within the used area of the main RAM 110b is backed up by the backup power supply after adding a checksum during power failure. The data backed up by the backup power supply is restored through data checking by the checksum. In the main ROM 110c of the main control board 110, programs and data for game control are stored, details of which will be described later.

[0069] Based on the performance control commands received from the main control board 110, the performance control board 120 controls the image display device 31, the audio output device 32, the performance driving devices 330a, 330b, 330c, and the performance lighting devices 340a, 340b, 340c, 340d, 340e.

[0070] The performance control board 120 includes a performance control unit 120m that controls the progress of the performance based on the reception of the performance control commands from the main control board 110, a display / audio control unit 140 that performs control processing for image display and audio output based on the reception of the performance control commands from the performance control unit 120m, a lamp / drive control unit 150 that performs control processing for light emission performance and prop movement performance based on the performance control commands from the performance control unit 120m, and input / output ports for performance control.

[0076] Based on the commands transmitted from the production control unit 120m, the overall CPU 141a of the overall control unit 141 receives the operating clock from the crystal oscillator, reads out the overall control program and data stored in the overall ROM 141c, and uses the overall RAM 141b as a work area to perform arithmetic processing related to image display and audio output. The overall CPU 141a outputs an audio control command instructing the audio to be output to the audio output device 32, which is generated by the arithmetic processing, to the audio processor 144, and outputs a display control command (such as a display list) instructing the production image to be displayed on the image display device 31 to the VDP 145.

[0077] The audio processor 144 is connected to the audio ROM 148. The audio ROM 148 stores compressed audio data. The audio processor 144 reads out and multiplexes the audio data from the audio ROM 148 based on the audio control command received from the overall control unit 141, and outputs the audio from the audio output device 32 with the multiplexed data.

[0078] The VDP 145 is connected to the CGROM 146. The CGROM 146 stores compressed image data, non-compressed palette data, etc. The image data is composed of pixel information about sprite images and movie images to be displayed on the image display device 31. The pixel information of the image data is composed of color number information and transparency (α value) for each pixel. The palette data is data in which color number information and display colors are associated.

[0079] The VDP 145 is provided with a VRAM 147. The VRAM 147 is provided with a display list storage area, a decompression area for compressed data, a first frame buffer area, and a second frame buffer area. The display list storage area is an area for storing the display list output from the overall control unit 141.

[0080] The first frame buffer area and the second frame buffer area are storage areas for storing display image data to be displayed on the image display device 31. While the drawing of the image to be displayed in one buffer area is finished and the transfer process of the image data is being performed on the image display device 31, the drawing of the next image to be displayed is performed in the other buffer area. By repeating this alternately, high-speed and smooth display control is realized.

[0081] VDP145 stores the display list output from the overall control unit 141, reads out the image data corresponding to the display list from the CGROM146, performs a drawing process using this image data in a frame buffer for drawing, and generates an RGB signal as a video signal indicating the color of the image from the image data stored in the frame buffer for display, and outputs the generated RGB signal to the image display device 31.

[0082] The lamp / drive control unit 150 includes a lamp CPU 150a that performs arithmetic processing, a lamp RAM 150b used as a work area when performing arithmetic processing, a lamp ROM 150c that stores a lamp control program and data, and an input / output port.

[0083] Based on the commands transmitted from the effect control unit 120m and the frame control board 160, the lamp CPU 150a of the lamp / drive control unit 150 receives the operation clock from the crystal oscillator, reads out the programs and data related to light emission control and accessory drive stored in the lamp ROM 150c, and uses the lamp RAM 150b as a work area to perform arithmetic processing related to light emission control and accessory drive processing. The lamp CPU 150a performs drive control of the effect driving devices 330a, 330b, 330c and light emission control of the effect lighting devices 340a, 340b, 340c, 340d, 340e by the arithmetic processing.

[0084] The frame control board 160 controls the counting of game balls, the launching control of game balls, etc. The frame control board 160 is connected to the main control board 110 so as to be communicable bidirectionally. The frame control board 160 includes a launch control unit 170, a game ball number control unit 180, an input port, an output port, and a game ball number clear switch 180e.

[0087] The launch control unit 170 includes a launch CPU 170a, a launch RAM 170b, and a launch ROM 170c. The launch CPU 170a reads programs and data stored in the launch ROM 170c and performs arithmetic processing using the launch RAM 170b as a work area. When the power-on operation is performed, the launch CPU 170a performs initial setting processing and then controls the launch of game balls, etc.

[0088] The game ball number control unit 180 includes a game ball number CPU 180a, a game ball number RAM 180b, and a game ball number ROM 180c. The game ball number CPU 180a reads programs and data stored in the game ball number ROM 180c and performs arithmetic processing using the game ball number RAM 180b as a work area.

[0089] When the power-on operation is performed, the game ball number CPU 180a performs initial setting processing and then, according to the progress of the game, performs processing related to subtraction and addition of the number of game balls that can be played, and control related to the operation of the count button detection switch 82a according to the progress of the game, etc.

[0090] The game ball number RAM 180c is provided with various storage areas such as an error 1 occurrence information storage area, an error 2 occurrence information storage area, an error 3 occurrence information storage area, an error 4 occurrence information storage area, a counting button operation valid flag storage area, a counting button operation invalid flag storage area, a game state flag storage area, a game machine information notification standby flag storage area, an away flag storage area, a game interruption determination flag storage area, a counting notification standby flag storage area, a communication failure determination counter, a game machine information notification standby timer counter, a counting notification standby timer counter, a game interruption determination timer counter, a game ball number counter, a launched ball number counter, a total prize ball number counter, and a counted ball number counter.

[0091] Here, at the time of power-off, the data in the used area of the game ball number RAM 180c is backed up by a backup power supply (not shown) after adding a checksum, and at the time of power recovery, this backup information is recovered through data check by the checksum.

[0092] The power supply board 175 generates the main power supply necessary for the operation of the gaming machine from the power supply supplied from the outside of the gaming machine via the power plug 176, and supplies the generated main power supply to the main control board 110, the effect control board 120, the frame control board 160, etc. of the gaming machine 1. The power supply board 175 includes a power failure detection circuit (not shown) that detects whether the voltage of the power supply supplied from the outside has dropped and outputs a voltage drop signal to the main control board 110 and the frame control board 160 based on the voltage drop, and a backup power supply circuit (not shown) for supplying a backup power supply to the main control board 110 and the frame control board 160 at the time of power failure.

[0093] (Block diagram of the entire card unit) As shown in FIG. 6, the card unit 9 is provided with a card unit control board 90, a card unit SC board 95, a power supply board 97, etc. When a power-on operation is performed on the card unit 9, power is supplied from the power supply board 97 to the card unit control board 90 and the card unit SC board 95, and these boards start operating.

[0094] The card unit control board 90 controls the basic operations of the card unit 9. Specifically, the card unit control board 90 performs analysis and processing of data received from the gaming machine 1, processing according to inserted bills or cards, processing related to buttons and displays provided on the card unit 9, generation processing of data to be transmitted to the gaming machine 1, the hall computer, etc.

[0095] The card unit SC board 95 controls communication between the card unit 9 and the outside. Specifically, it controls communication between the card unit 9 and the gaming machine 1, a server of the management center (not shown), and a hall computer (not shown).

[0096] As shown in FIG. 6, the card unit control board 90 includes a one-chip microcomputer 910m having a unit CPU 910a, a unit RAM 910b, and a unit ROM 910c, an input port, an output port, etc.

[0097] Connected to the input port of the card unit control board 90 are a card reader / writer 92a, a lending button detection SW 98a, a discharge button detection SW 99a, and a bill discriminator 91a. The lending button detection SW 98a outputs a signal indicating that the lending button has been pressed. The discharge button detection SW 99a outputs a signal indicating that the discharge button has been pressed.

[0098] Connected to the output port of the card unit control board 90 are a card reader / writer 92a, an amount display 93, and a number of balls in hand display 94.

[0099] The card unit control board 90 includes a unit CPU 910a, a unit RAM 910b, and a unit ROM 910c. The unit CPU 910a reads programs and data stored in the unit ROM 910c and performs arithmetic processing using the unit RAM 910b as a work area.

[0100] In the unit RAM 910b of the card unit control board 90, various storage areas are provided, such as an amount information storage area, a number of balls in hand information storage area, a lending receipt result response waiting flag storage area, a game state flag storage area, an ejection button operation invalid flag storage area, a lending button operation invalid flag storage area, and a lending receipt result response waiting timer counter. In the unit ROM 910c of the card unit control board 90, programs and various data for controlling the card unit 9 are stored.

[0101] (Flow of lending operation, counting operation, card insertion operation, and card ejection operation) Next, with reference to FIG. 7, the flow of the game ball lending operation performed by the card unit 9 will be described. When a bill 200 is inserted into the bill insertion slot 91 of the card unit 9 (FIG. 7(a)), a number indicating the amount of the inserted bill (in the example of FIG. 7, "5" indicating 5000 yen) is displayed on the amount display 93 (FIG. 7(b)).

[0102] When the lending button 98 is pressed once in this state (FIG. 7(c)), on the amount display 93 of the card unit 9, "4" indicating that the amount data (5000 yen) stored in the card unit 9 has decreased by 1000 yen to 4000 yen is displayed, and "250" is displayed on the game ball number display 84 of the gaming machine 1 (FIG. 7(d)). The reason why the amount of 1000 yen decreases and 250 game balls are lent out is that the lending is made at 4 yen per shot.

[0103] Also, when the player presses the lending button 98 once again in the state shown in FIG. 7(d) for the card unit 9 and the gaming machine 1, a lending operation for another 1000 yen worth of game balls becomes possible. Specifically, when the lending button 98 is pressed once again in the state of FIG. 7(d), "3" is displayed on the amount display 93 of the card unit 9, and "500" is displayed on the game ball number display 84 of the gaming machine 1.

[0104] However, when the lending button 98 is pressed while the card 201 storing the number of balls in hand data is inserted into the card unit 9, lending by subtracting the amount data is not performed, and lending by subtracting the number of balls in hand data is preferentially performed.

[0105] Next, with reference to FIG. 8, the flow of the counting operation performed on the gaming machine 1 will be described. When the counting button 82 is briefly pressed once while the number of gaming balls is displayed on the gaming ball number display 84 of the gaming machine 1, the number of gaming balls displayed on the gaming ball number display 84 is decremented by 1 and displayed, and at the same time, the display of the number of balls in hand display 94 of the card unit 9 is incremented by 1 and displayed.

[0106] For example, when the counting button 82 is briefly pressed once while "12345" is displayed on the gaming ball number display 84 of the gaming machine 1 (FIG. 8(a-1)), "12344" is displayed on the gaming ball number display 84, and at the same time, the display of the number of balls in hand display 94 of the card unit 9 is updated from "0" to "1" and displayed (FIG. 8(a-2)).

[0107] Also, when the counting button 82 is long-pressed once while the number of gaming balls is displayed on the gaming ball number display 84 of the gaming machine 1, the number of gaming balls displayed on the gaming ball number display 84 is decremented by 250 and displayed, and at the same time, the display of the number of balls in hand display 94 of the card unit 9 is incremented by 250 and displayed.

[0108] For example, when the counting button 82 is long-pressed once while "12345" is displayed on the gaming ball number display 84 of the gaming machine 1 (FIG. 8(b-1)), "12095" is displayed on the gaming ball number display 84, and at the same time, the display of the number of balls in hand display 94 of the card unit 9 is updated from "0" to "250" and displayed (FIG. 8(b-2)).

[0109] Next, the process of the ejection operation and insertion operation of the card 201 will be described with reference to FIG. 9. When the ejection button 99 of the card unit 9 is pressed, the amount data displayed on the amount display 93 and the number of balls in hand data displayed on the number of balls in hand display 94 at that time are written into the card 201, and the card 201 with the amount data and the number of balls in hand data written therein is ejected from the card insertion slot 92.

[0110] For example, when the ejection button 99 is pressed in a state where "4" is displayed on the amount display 93 of the card unit 9 and "1234" is displayed on the number of balls in hand display 94 (FIG. 9(a-1)), the card 201 storing the amount data of 4000 yen and the number of balls in hand data of 1234 is ejected from the card insertion slot 92 (FIG. 9(a-2)).

[0111] Note that when the ejection button of the card unit 9 is pressed while the number of balls in hand is displayed on the number of game balls display 84 of the gaming machine 1, the writing of the amount data and the number of balls in hand data to the card 201 and the ejection of the card 201 are not performed. Therefore, when the player wants to eject the card 201 in the above state, the player performs a counting operation of pressing the counting button 82 of the gaming machine 1 to transfer all the number of balls in hand data stored in the gaming machine 1 to the card unit 9, and then presses the ejection button 99 of the card unit 9 to eject the card 201.

[0112] When the player inserts the card 201 storing the amount data and the number of balls in hand data into the card insertion slot, the card 201 is stored in the card unit 9, the amount data stored in the card 201 is displayed on the amount display 93, and the number of balls in hand data stored in the card 201 is displayed on the number of balls in hand display 94.

[0113] For example, when the card 201 storing the amount data of 4000 yen and the number of balls in hand data of 1234 is inserted into the card insertion slot 92 (FIG. 9(b-1)), the card 201 is stored in the card unit 9, "4" is displayed on the amount display 93, and "1234" is displayed on the number of balls in hand display 94.

[0114] However, when an amount is displayed on the amount display 93 or when the number of balls remaining is displayed on the number of balls remaining display 94, the card unit 9 will not accept the insertion of the card 201 into the card insertion slot.

[0115] (Game status of gaming machine 1) The gaming machine 1 has a normal state and a low base time-saving state in which the game is played by hitting from the left, and a high base time-saving state in which the game is played by hitting from the right. In these gaming states, the ease of winning the game ball into the second starting hole 15 is different.

[0116] The gaming machine 1 executes a normal pattern lottery when the starting condition for the normal pattern is met based on the passage of the gaming ball through the normal pattern gate 13. If the result of the normal pattern lottery is a win, the normal pattern is displayed in a variable manner for a predetermined time, then stops in a winning manner, and the movable piece 15b is controlled to open in a predetermined manner. If the result of the normal pattern lottery is a loss, the normal pattern is displayed in a variable manner for a predetermined time, then stops in a losing manner.

[0117] As shown in Fig. 10, the normal symbol variation time is 90 seconds in the normal state, 89 seconds in the low base time-saving state, and 4 seconds in the high base time-saving state. In addition, the opening control time of the movable piece 15b when the result of the normal symbol lottery is a win is 0.1 seconds in the normal state, 0.11 seconds in the low base time-saving state, and 8 seconds in the high base time-saving state.

[0118] The shorter the normal symbol fluctuation time, the more opportunities there are for the normal symbol to be drawn, and the longer the opening time of the movable piece 15b when the normal symbol lottery result is a winning symbol, the more opportunities there are for the game ball to win, and the higher the likelihood of the game ball winning. Therefore, in the high base time-saving state, the normal symbol fluctuation time is significantly shorter than in the normal state and the low base time-saving state, and the opening time of the second start hole 15 is also significantly longer, so that the ease of the game ball winning in the second start hole 15 is higher than in the normal state and the low base time-saving state.

[0119] On the other hand, in the low base short state, compared with the normal state, the variation time of the normal symbol is slightly shorter, and the opening time of the second start port 15 is also slightly longer. Therefore, the winning probability of the game ball entering the second start port 15 is higher than that in the normal state.

[0120] Therefore, the winning probability of the game ball entering the second start port 15 increases in the order of the high base short state, the low base short state, and the normal state. Therefore, if the winning probability of the game ball entering the second start port 15 is higher, the game state is more advantageous to the player. Then, the game state is more advantageous to the player in the order of the high base short state, the low base short state, and the normal state.

[0121] Also, as shown in FIG. 10, in the game state of the gaming machine 1, in addition to the three game states (normal state, low base short state, high base short state) with different winning probabilities of the game ball entering the second start port 15 described above, there are a game impossible state 1 and a game impossible state 2.

[0122] The game impossible state 1 is a game state in which the game is not executed due to a complete function activation error occurring in the main control board 110. The complete function activation error is an error that occurs to limit the execution of further games when the maximum number of game balls obtained in the gaming machine 1 exceeds the upper limit value of 95,000 per day.

[0123] The game impossible state 2 is a game state in which the game is not executed due to a specific error occurring in the frame control board 160. The specific errors in the frame control board 160 include a small ball detection error, an iron ball detection error, and a radio wave detection error.

[0124] In this embodiment, since a non-magnetic game ball is used, an iron ball error is detected. However, when a magnetic game ball is used, a magnet error may be detected instead of the iron ball error.

[0125] (Game flow) Next, the game flow of the gaming machine 1 will be described using the game flow of the gaming machine 1. FIG. 11 is a diagram showing the game flow of the gaming machine 1.

[0126] Based on the establishment of the start condition of the first special symbol upon the winning of a game ball in the first start port 14 and the establishment of the start condition of the second special symbol upon the winning of a game ball in the second start port 15, the jackpot lottery is executed. When the special symbol lottery result is a jackpot, after the special symbol performs a variable display for a predetermined time, it stops in the jackpot stop mode, and the first big winning port 16 is controlled to open in a predetermined mode. When the special symbol lottery result is a minor jackpot, after the special symbol performs a variable display for a predetermined time, it stops in the minor jackpot stop mode, and the second big winning port 17 is controlled to open in a predetermined mode. When the special symbol lottery result is a loss, after the special symbol performs a variable display for a predetermined time, it stops in the loss stop mode. Note that there are two types of losses: normal loss and special loss.

[0127] The special loss is a loss that is selected only by the jackpot lottery conducted upon the establishment of the start condition of the first special game, and it is composed of four types: special loss a, special loss b, special loss c, and special loss d. When the special loss is established in the normal state, the game state shifts to the low base short state or the high base short state.

[0128] The gaming machine 1 is provided with six types of first-class jackpots and three types of second-class jackpots. The first-class jackpot is a special game in which, after the special symbol stops at the jackpot symbol, the first big winning port 16 is controlled to open in a predetermined mode. The second-class jackpot is a special game that is performed on the condition that a game ball passes through the specific area 19B when the special symbol stops at the minor jackpot symbol and the second big winning port 17 is controlled to open in a predetermined mode.

[0129] Among the first-class jackpots, there are four types of special games (first-class 10R jackpot A, first-class 2R jackpot B, first-class 2R jackpot C, first-class 10R jackpot D) executed when the first special symbol stops at the jackpot symbol, and two types of special games (first-class 10R jackpot F, first-class 2R jackpot G) executed when the second special symbol stops at the jackpot symbol.

[0130] For the first type, A per 10R, D per 10R, and F per 10R, a round game in which the first major winning opening 16 is controlled in an open state where a game ball can win is conducted 10 times. In each round game, until a predetermined number of game balls (for example, 9 balls) win in the first major winning opening 16 or the opening time of the first major winning opening 16 reaches a predetermined time (for example, 29 seconds), the first major winning opening 16 is controlled to be open.

[0131] For the first type, B per 2R, C per 2R, and G per 2R, a round game in which the first major winning opening 16 is controlled in an open state where a game ball can win is conducted 2 times. In each round game, until a predetermined number of game balls (for example, 9 balls) win in the first major winning opening 16 or the opening time of the first major winning opening 16 reaches a predetermined time (for example, 29 seconds), the first major winning opening 16 is controlled to be open.

[0132] For the second type jackpot, there are three types of special games (H per 9R of the second type, I per 2R of the second type, J per 9R of the second type) that are executed when the second special symbol stops at the minor winning symbol and a game ball passes through the specific area 19B during the minor win.

[0133] For the second type, H per 9R and J per 9R, a round game in which the first major winning opening 16 is controlled in an open state where a game ball can win is conducted 9 times. In each round game, until a predetermined number of game balls (for example, 9 balls) win in the first major winning opening 16 or the opening time of the first major winning opening 16 reaches a predetermined time (for example, 29 seconds), the first major winning opening 16 is controlled to be open.

[0134] For the second type, I per 2R, a round game in which the first major winning opening 16 is controlled in an open state where a game ball can win is conducted 2 times. In each round game, until a predetermined number of game balls (for example, 9 balls) win in the first major winning opening 16 or the opening time of the first major winning opening 16 reaches a predetermined time (for example, 29 seconds), the first major winning opening 16 is controlled to be open.

[0135] Hereinafter, the game flow of the gaming machine 1 will be described with reference to FIG. 11. When A for a first - type 10R hit or B for a first - type 2R hit is established in the normal state, the game state after the special game ends returns to the normal state. When C for a first - type 2R hit or D for a first - type 10R hit is established in the normal state, the game state after the special game ends becomes a high - base short - time state where the upper limit of the high - base short - time count (J) is 100 times.

[0136] When special miss a is established in the normal state, the game state becomes a high - base short - time state where the upper limit of the high - base short - time count (J) is 100 times. When special miss b, special miss c, or special miss d is established in the normal state, the game state becomes a low - base short - time state. The upper limits of the low - base short - time counts (B) of the low - base short - time states shifted by the establishment of the above three types of special misses are 600 times (special miss b), 400 times (special miss c), and 200 times (special miss d), respectively. In the case of a normal miss, which is a miss other than the above four types of special misses, the game state does not shift (however, this does not apply when the variable count (L) described later reaches 800 times).

[0137] When C for a first - type 2R hit is established in the low - base short - time state, the game state after the special game ends becomes a low - base short - time state where the upper limit of the low - base short - time count (B) is 100 times. When A for a first - type 10R hit or B for a first - type 2R hit is established in the low - base short - time state, the game state after the special game ends returns to the normal state. When D for a first - type 10R hit is established in the low - base short - time state, the game state after the special game ends becomes a high - base short - time state where the upper limit of the high - base short - time count (J) is 100 times.

[0138] When a special miss or a normal miss is established in the low - base short - time state and the low - base short - time count (B) reaches a predetermined number of times (100 times, 200 times, 400 times, 600 times), the game state returns to the normal state.

[0139] In either the normal state or the short low-base state, if a special loss or a normal loss occurs and the number of fluctuations (L) reaches 800 times, the game state will change to the short high-base state where the upper limit of the number of short high-base times (J) is 100 times.

[0140] In the short high-base state, if F occurs for the first type 10R, G occurs for the first type 2R, H occurs for the second type 9R, or I occurs for the second type 2R, the game state after the special game ends will again become the short high-base state where the upper limit of the number of short high-base times (J) is 100 times. In the short high-base state, if J occurs for the second type 9R, the game state after the special game ends will become the normal state. In the short high-base state, if a special loss or a normal loss occurs and the number of short high-base times (J) reaches 100 times, the game state will become the normal state.

[0141] As shown in the above game flow, the short low-base state is a game state where it is more difficult to transition to the short high-base state than the normal state. Specifically, the conditions for transitioning from the short low-base state to the short high-base state are that the number of fluctuations (L) reaches 800 times and winning for D in the first type 10R. However, the conditions for transitioning from the normal state to the short high-base state also include the occurrence of a special loss a and the occurrence of C in the first type 2R in addition to the above two conditions.

[0142] Therefore, in terms of the easiness of winning a game ball into the second start port 15, the short low-base state is higher than the normal state. However, in terms of the easiness of transitioning to the most advantageous short high-base state, the normal state is higher than the short low-base state. Therefore, when the player is in the short low-base state, the player will play the game aiming to transition to the normal state. Specifically, when the player is in the short low-base state, the player will play the game aiming for the occurrence of A in the first type 10R or B in the first type 2R, or aiming to complete the specified number of short low-base times (B).

[0143] As a route to shift to the high-base short state, in addition to the route that shifts from the normal state, there is also a route that directly shifts from the low-base short state to the high-base short state. Specifically, in the low-base short state, when D is established per 10R of the first type or the number of fluctuations (L) reaches 800 times, it shifts from the low-base short state to the high-base short state. Therefore, even when the player is staying in the low-base short state, if D is established per 10R of the first type, they will shift to the high-base short state, so it becomes possible to play the game with a constant expectation of shifting to the high-base short state.

[0144] Furthermore, even when the player is staying in the low-base short state, when the number of remaining fluctuations (L) is only a few times until it reaches 800 rotations, by consuming the remaining few fluctuation displays, the number of fluctuations (L) reaches 800 times and they can surely shift to the high-base short state, so it becomes possible to play the game with a very high expectation.

[0145] Also, when shifting to the high-base short state, if F per 10R of the first type, G per 2R of the first type, H per 9R of the second type, and I per 2R of the second type continue to be established until J per 9R of the second type is established, the high-base short state will continue after the special game ends, so it becomes possible to obtain a large number of game balls. Also, the game state after passing through the high-base short state when J per 9R of the second type is established shifts to the normal state where it is easy to shift to the high-base short state, so it can be expected to return to the high-base short state in a short period of time.

[0146] (Mode background image) Next, the background image of the production mode according to the game state of the gaming machine 1 will be described. FIG. 12 is a diagram showing the mode background image of the gaming machine 1.

[0147] As shown in FIG. 12, the gaming machine 1 has three production modes: a ground mode, a sea mode, and an underwater temple mode. The ground mode is a production mode corresponding to the short state at the low base. The sea mode is a production mode corresponding to the normal state. The underwater temple mode is a production mode corresponding to the short state at the high base. However, although details will be described later, the production mode and the gaming state generally have the correspondence relationship described above, but there are also exceptions where the correspondence relationship is not as described above.

[0148] In the ground mode, a ground background image (rural background, urban background, desert background) is displayed. In the sea mode, an underwater background image (shallow seabed background, deep sea background) is displayed. In the underwater temple mode, an underwater temple background image is displayed.

[0149] From the perspective of the game flow, since the gaming state becomes a more advantageous gaming state in the order of the short state at the high base, the normal state, and the short state at the low base as described above, the background image of the production mode is set so that it becomes a more advantageous background image as it approaches the seabed.

[0150] Note that in the ground mode, there are three types of background images: a rural background image, an urban background image, and a desert background image, but the background image to be displayed may be changed according to the progress of the number of times of the short number of times (B) at the low base. For example, the closer the remaining number of times until the specified consumption of the short number of times at the low base is, the easier it may be to display the desert background image, the urban background image, and the rural background image in this order.

[0151] Also, as will be described later, when shifting to the sea mode in any gaming state of the short state at the low base and the normal state under predetermined conditions, the length of the stay period of the display of the shallow seabed background image and the deep sea background image and the transition state may be used to suggest to the player which gaming state it is. In that case, for example, it may be suggested that the higher the possibility of the normal state is as the deep sea background image is more frequently displayed.

[0152] (Command transmission and reception between the frame control board, the main control board, and the card unit) The main control board 110 of the gaming machine 1 generates a gaming machine information notification command and transmits the generated gaming machine information notification command to the frame control board 160. The gaming machine information notification command is a command that includes information indicating the gaming state of the gaming machine 1 and the status of the progress and stop of the game.

[0153] Specifically, the gaming machine information notification command is a command that includes information indicating the presence or absence of a complete function activation error, information indicating that a game ball has won a prize at the start port, information indicating that a game ball has won a prize at the big prize port, and the like.

[0154] When the frame control board 160 receives the gaming machine information notification command from the main control board 110, it transmits a response command to the main control board 110. The main control board 110 checks whether the response command has been received and determines whether a communication failure has occurred according to the reception status of the response command.

[0155] FIG. 13 is a diagram showing an example of the transmission and reception of the gaming machine information notification command and the response command between the main control board 110 and the frame control board 160. As shown in FIG. 13, the main control board 110 transmits the gaming machine information notification command to the frame control board 160 every 108 ms. When the situation where the response command is not transmitted from the frame control board 160 within 10 ms after the main control board 110 transmits the gaming machine information notification command occurs continuously 10 times, it is determined that a communication failure has occurred, and a communication failure occurrence notification is displayed on the image display device 31. The details of the gaming machine information notification process of the main control board 110 will be described later.

[0156] As shown in FIG. 14, the frame control board 160 of the gaming machine 1 transmits the gaming machine information notification data to the card unit 9 every 300 ms. The details of the gaming machine information notification process of the frame control board 160 will be described later.

[0157] Note that the gaming machine information notification data includes information indicating the gaming state of gaming machine 1, information indicating whether gaming machine 1 is in a jackpot state, information indicating the presence or absence of a complete function activation error, information indicating the occurrence or non-occurrence of a small ball detection error, information indicating the occurrence or non-occurrence of an iron ball detection error, information indicating the occurrence or non-occurrence of a radio wave detection error, information indicating the number of gaming balls, information indicating the number of launched balls, information indicating the total number of prize balls, information indicating winning at the start port, and information indicating winning at the big winning port, etc.

[0158] As shown in FIG. 15, after transmitting the gaming machine information notification data to the card unit 9, the frame control board 160 transmits the count notification data to the card unit 9 100 ms later. Note that the count notification data is data indicating the number of gaming balls transferred from gaming machine 1 to the card unit 9. Details of the count notification process of the card unit control board 90 will be described later.

[0159] As shown in FIG. 16, when the card unit 9 receives a lending operation by operating the lending button 98, it transmits lending notification data to the frame control board 160. The lending notification data is data indicating the number of gaming balls that can be used for gaming on gaming machine 1 transferred from the card unit 9 to gaming machine 1.

[0160] When the frame control board 160 receives the lending notification data from the card unit 9, it transmits lending receipt result response data to the card unit 9. If the card unit 9 does not receive the lending receipt result response data from the frame control board 160 within 10 ms after transmitting the lending notification data, it retransmits the lending notification data. Details of the lending process and the response confirmation process of the card unit 9 will be described later.

[0161] (Regarding the power-on operation of the gaming machine) When a power-on operation is performed by operating the power switch 177 provided on the back surface of gaming machine 1, power is supplied from the power board 175 to the main control board 110, the effect control board 120, and the frame control board 160, and each board starts operating.

[0162] The power-on operation of the gaming machine 1 has four types: normal power-on operation, main control board RAM clear power-on operation, frame control board RAM clear power-on operation, and all RAM clear power-on operation. The following describes the above four types of power-on operations with reference to FIG. 17.

[0163] The normal power-on operation is executed by turning on the power switch SW177 without pressing the RAM clear switch SW111a and the game ball count clear switch SW180e (FIG. 17(a-1)). (FIG. 17(a-2)).

[0164] The main control board RAM clear power-on operation is executed by turning on the power switch SW177 while pressing the RAM clear switch SW111a and not pressing the game ball count clear switch SW180e (FIG. 17(b-1)). (FIG. 17(b-2)). When power-on is performed by the main control board RAM clear power-on operation, an initialization process involving clearing all areas of the main RAM 110b of the main control board 110 is performed. Details of the initialization process of the main control board 110 will be described later.

[0165] The frame control board RAM clear power-on operation is executed by turning on the power switch SW177 while not pressing the RAM clear switch SW111a and pressing the game ball count clear switch SW180e (FIG. 17(c-1)). (FIG. 17(c-2)). When power-on is performed by the frame control board RAM clear power-on operation, an initialization process involving clearing all areas of the game ball count RAM 180b of the frame control board 160 is performed. Details of the initial setting process of the frame control board 160 will be described later.

[0166] The all RAM clear power-on operation is executed by turning on the power switch SW177 while pressing the RAM clear switch SW111a and the game ball count clear switch SW180e (FIG. 17(d-1)). (FIG. 17(d-2)). When power-on is performed by the all RAM clear power-on operation, initialization processes of each board involving clearing all areas of the main RAM 110b of the main control board 110 and all areas of the game ball count RAM 180b of the frame control board 160 are performed.

[0167] Next, various tables stored in the main ROM 110c will be described. FIG. 18 is a diagram showing the winning or losing lottery determination tables for the special symbols and the normal symbols of the gaming machine 1.

[0168] (Winning or losing lottery determination table) Specifically, FIG. 18(a) is the jackpot lottery determination table for the first special symbol display device, FIG. 18(b) is the jackpot lottery determination table for the second special symbol display device, and FIG. 18(c) is the winning lottery determination table for the normal symbol display device.

[0169] As shown in FIG. 18(a), the lottery results by the first special symbol are of three types: jackpot, special loss, and normal loss. As shown in FIG. 18(b), the lottery results by the second special symbol are of three types: jackpot, small win, and normal loss. The main CPU 110a refers to the jackpot lottery determination tables shown in FIGS. 18(a) and 18(b), and determines the lottery result based on the obtained jackpot random number value.

[0170] As shown in FIG. 18(c), the lottery result by the normal symbol is either a win or a loss. The main CPU 110a refers to the winning lottery determination table shown in FIG. 18(c), and determines the lottery result based on the obtained normal symbol random number value. As shown in FIG. 18(c), the winning probability by the normal symbol lottery is the same in the normal state, the short low base state, and the short high base state. However, the winning probability by the normal symbol lottery may be changed according to the gaming state.

[0171] (Symbol determination table) FIG. 19 is a diagram showing the jackpot and small win symbol determination tables of the gaming machine 1. Specifically, FIG. 19(a) is the symbol determination table for the jackpot. In the symbol determination table for the jackpot, the type of the special symbol display device, the special symbol random number value, the type of the special symbol (type of the jackpot), the stopped symbol data, and the symbol designation command are associated.

[0172] FIG. 19(b) is a winning symbol determination table for small wins. In the winning symbol determination table for small wins, a special symbol random value, the type of special symbol (the type of jackpot executed by winning in the specific area 19B), stop symbol data, and a symbol designation command are associated. In the gaming machine 1, a small win is established only by the lottery of the second special symbol, but a small win may be established according to the lottery result of the first special game.

[0173] The symbol designation command is composed of 1-byte MODE data indicating the classification of the control command and 1-byte DATA indicating the content of the control command to be executed. Also, for control commands (for example, variable pattern designation commands, etc.) transmitted from other main control boards 110 described later to the effect control unit 120m, the data configuration of the commands is the same as that of the symbol designation command.

[0174] FIG. 20 is a diagram showing a symbol determination table for losing symbols of the gaming machine 1. Specifically, FIG. 20(a) is a symbol determination table for special losses. FIG. 20(b) is a symbol determination table for normal losses.

[0175] As shown in FIG. 18, since a special loss is selected only in the winning or losing lottery by the first special symbol, the symbol determination table for special losses shown in FIG. 20(a) describes only the data associated with the first special symbol display device 20. In the symbol determination table for special losses, a special symbol random value, the type of special symbol (the type of special loss), stop symbol data, and a symbol designation command are associated. In the symbol determination table for normal losses shown in FIG. 20(b), the type of special symbol display device, a special symbol random value, the type of special symbol (the type of normal loss), and stop symbol data are associated.

[0176] When the variation of the special symbol starts, the main CPU 110a determines a symbol designation command based on the symbol determination tables shown in FIGS. 19 and 20 and the acquired special symbol random value, and transmits the determined symbol designation command to the effect control unit 120m.

[0177] (Special game end setting table) FIG. 21 is a special game end setting table for determining the game state after the special game of the gaming machine 1 ends.

[0178] In the special game end setting table, the type of the special symbol display device, the type of the special symbol, the stop symbol data, the game state information set in the game state buffer, the game state at the end of the special game, the short number of times (B) in the low base state, and the short state (J) in the high base state are associated.

[0179] The "game state buffer" is a storage area provided in the main RAM 110b, and is a storage area in which information indicating the game state during the variation when a big win is won is stored. As described above, the game state of the gaming machine 1 is composed of a normal state, a short state in the low base state, and a short state in the high base state.

[0180] When the game state information in the game state buffer is "00H" during the variation when a big win is won, the game state is the normal state; when the game state information in the game state buffer is "01H", the game state is the short state in the low base state; when the game state information in the game state buffer is "02H", the game state is the short state in the high base state.

[0181] The main CPU 110a refers to the special game end setting table shown in FIG. 21, and determines the game state after the special game ends, the short number of times (B) in the low base state, and the short number of times (J) in the high base state based on the stop data of the special symbol and the game state information in the game state buffer.

[0182] Although it partially overlaps with the game flow described with reference to FIG. 11 below, the change in the game state when each big win symbol stops as a special symbol will be described.

[0183] When the special symbol A stops (when A is selected for the first type 10R win), and when the special symbol B stops (when B is selected for the first type 2R win), the game state after the special game ends is the normal state regardless of the game state information in the game state buffer.

[0184] When the special symbol C stops (when C is selected for the first type of 2R hit), the game state after the special game ends is a high base short state where the upper limit of the high base short count (J) is 100 times if the game state information in the game state buffer is in the normal state, and a low base short state where the upper limit of the low base short count (B) is 100 times if the game state information in the game state buffer is in the low base short state or the high base short state.

[0185] When the special symbol D stops (when D is selected for the first type of 10R hit), the game state after the special game ends is a high base short state where the upper limit of the high base short count (J) is 100 times regardless of the game state information in the game state buffer.

[0186] When the special symbol F stops (when F is selected for the first type of 10R hit), when the special symbol G stops (when G is selected for the first type of 2R hit), when the special symbol H stops (when H is selected for the second type of 9R hit), and when the special symbol I stops (when I is selected for the second type of 2R hit), the game state after the special game ends is a high base short state where the upper limit of the high base short count (J) is 100 times regardless of the game state information in the game state buffer.

[0187] When the special symbol J stops (when J is selected for the second type of 9R hit), the game state after the special game ends is the normal state regardless of the game state information in the game state buffer.

[0188] In this embodiment, as the jackpot based on the lottery result of the second special symbol that transitions from the high base short state to the normal state after the end, only J for the second type of 9R hit is provided, but a plurality of types of jackpots based on the lottery result of the second special symbol that transitions from the high base short state to the normal state after the end may be provided. Also, as the jackpot based on the lottery result of the second special symbol that transitions from the high base short state to the normal state after the end, instead of 2 types per hit, 1 type per hit may be provided.

[0189] In addition, in this embodiment, when shifting from the normal state to the high-base short-time state triggered by a big win, the upper limit number of times of the high-base short-time (J) is set to the same 100 times for any big win case. However, the upper limit number of times of the high-base short-time (J) may be made different according to the type of the established big win.

[0190] In addition, in this embodiment, when shifting from the normal state to the high-base short-time state triggered by a big win, and when shifting to the high-base short-time state triggered by a special loss or a normal loss being established and the number of fluctuation times (L) reaching 800 times, the upper limit number of times of the high-base short-time (J) is set to the same 100 times. However, different upper limit numbers of times may be set respectively.

[0191] (Special loss symbol and normal loss symbol stop setting table) FIG. 22 is a diagram showing a special loss symbol stop setting table for determining the game state after the special loss symbol of the gaming machine 1 stops.

[0192] In the special loss symbol stop setting table, the type of the special symbol display device, the type of the special symbol, the stop symbol data, the game state before the symbol stops, the game state at the time of symbol stop, the low-base short-time number of times (B), and the high-base short-time number of times (J) are associated.

[0193] Although it partially overlaps with the game flow described with reference to FIG. 11 below, the change in the game state when each loss symbol stops as a special symbol will be described.

[0194] When the special symbol a stops (when the special loss a is selected), if the game state before the symbol stops is the normal state, the game state becomes the high-base short-time state where the upper limit number of times of the high-base short-time (J) is 100 times. If the game state before the symbol stops is the low-base short-time state, the game state and the low-base short-time number of times (B) are maintained. If the game state before the symbol stops is the high-base short-time state, the game state and the high-base short-time number of times (J) are maintained.

[0195] When the special symbol b stops (when special loss b is selected), the gaming state is as follows: if the gaming state before the symbol stops is the normal state, it becomes the low-base short state with the upper limit of the low-base short number of times (B) being 600 times; if the gaming state before the symbol stops is the low-base short state, the gaming state and the low-base short number of times (B) are maintained; if the gaming state before the symbol stops is the high-base short state, the gaming state and the high-base short number of times (J) are maintained.

[0196] When the special symbol c stops (when special loss c is selected), the gaming state is as follows: if the gaming state before the symbol stops is the normal state, it becomes the low-base short state with the upper limit of the low-base short number of times (B) being 400 times; if the gaming state before the symbol stops is the low-base short state, the gaming state and the low-base short number of times (B) are maintained; if the gaming state before the symbol stops is the high-base short state, the gaming state and the high-base short number of times (J) are maintained.

[0197] When the special symbol d stops (when special loss d is selected), the gaming state is as follows: if the gaming state before the symbol stops is the normal state, it becomes the low-base short state with the upper limit of the low-base short number of times (B) being 200 times; if the gaming state before the symbol stops is the low-base short state, the gaming state and the low-base short number of times (B) are maintained; if the gaming state before the symbol stops is the high-base short state, the gaming state and the high-base short number of times (J) are maintained.

[0198] Although not described in the table shown in FIG. 22, when the special symbol y stops (when normal loss is selected by the lottery of the first special symbol) and when the special symbol z stops (when normal loss is selected by the lottery of the second special symbol), the gaming state is different from when special loss is selected, and the transition of the gaming state does not occur.

[0199] When special losing and normal losing are selected, the gaming state at the time of symbol stop is as described above, but there are cases where the control of the gaming state is different from the above control. Specifically, when the number of fluctuations (L) reaches 800 times in the normal state or the low base short state, the gaming state, regardless of the type of losing symbol, becomes the high base short state where the upper limit of the high base short count (J) is 100 times. Also, when the high base short count (J) reaches 100 times in the high base short state, the gaming state, regardless of the type of losing symbol, becomes the normal state.

[0200] In this embodiment, only one special losing a is provided as a special losing that transitions to the high base short state in the normal state, but multiple types of special losing that transition to the high base short state may be provided. Also, in that case, the upper limit of the high base short count (J) may be set to different numbers according to the type of special losing that has occurred.

FIG. 24(a) is a diagram showing the big winning opening / closing control table for the first type of big hit. In the big winning opening / closing control table for the first type of big hit, the table number, round number, type of big winning opening, special electric operation number, and the opening time and closing time of the big winning opening in each round game are associated with each other.

[0210] As described above, the first type of big hit includes a 10R big hit and a 2R big hit. The opening control of the big winning opening in each round game is performed by referring to the table number "01" and the table number "02".

[0211] The main CPU 110a, which will be described in detail later, refers to the big winning opening / closing control table for the first type of big hit and performs the opening control and closing control of the first big winning opening 16 based on the table number when performing the round game in the first type of big hit.

[0215] FIG. 25 is a diagram showing the small winning large winning opening / closing control table and the small winning specific area opening / closing control table of the gaming machine 1. FIG. 25(a) is a diagram showing the small winning large winning opening / closing control table. In the small winning large winning opening / closing control table, the table number, the round number, the type of the large winning opening, the special electric operation number, and the opening time and closing time of the large winning opening are associated with each other.

[0216] The main CPU 110a, which will be described in detail later, refers to the small winning large winning opening / closing control table and performs opening control and closing control of the second large winning opening 17 when conducting a small winning game. Note that the opening / closing control of the large winning opening in the small winning is only one type of opening / closing control that repeats the 0.1-second opening and 0.05-second closing of the second large winning opening 17 ten times.

[0217] In this embodiment, the pattern of the opening control and closing control of the second large winning opening 17 in the small winning game is set to one type, but a plurality of types of patterns may be provided. In that case, by providing a plurality of types of opening / closing control patterns of the second large winning opening 17 with different ease of entry of the game balls into the specific area 19B during the small winning game, the ease of occurrence of the second jackpot based on the entry of the game balls into the specific area 19B according to the type of the small winning may be made different. Also, among the plurality of types of opening / closing control patterns of the second large winning opening 17, by providing a pattern in which game balls can easily enter the specific area 19B when a normal game is being played and a pattern in which it is difficult for game balls to enter the specific area 19B, the ease of occurrence of the second jackpot may be changed.

[0218] FIG. 25(b) is a diagram showing a specific area opening / closing control table for minor hits. In the specific area opening / closing control table for minor hits, the elapsed time since the second major winning opening 17 is opened, the opening time when the specific area 19B is opened by the slide member 19C being in the retracted state, and the closing time when the specific area 19B is closed by the slide member 19C being in the advanced state are associated with each other.

[0219] In the present embodiment, although there is one pattern for the opening control and closing control of the specific area 19B in the minor hit game, a plurality of types of patterns may be provided. In that case, by providing a plurality of types of opening / closing control patterns for the specific area 19B with different ease of entry of game balls into the specific area 19B during the minor hit game, the ease of occurrence of the second type of big hit based on the entry of game balls into the specific area 19B may be made different. Further, among the plurality of types of opening / closing control patterns for the specific area 19B, by providing a pattern in which game balls easily enter the specific area 19B during normal games and a pattern in which it is difficult for game balls to enter the specific area 19B, the ease of occurrence of the second type of big hit may be changed.

[0220] The main CPU 110a, although described in detail later, refers to the specific area opening / closing control table for minor hits and performs opening control and closing control of the specific area 19B when conducting a minor hit game.

[0221] (Special symbol variation pattern determination table) FIGS. 26, 27, 28, and 29 are diagrams showing a special symbol variation pattern determination table referred to for determining the variation pattern of the first special symbol or the second special symbol of the gaming machine 1.

[0222] Specifically, the variation pattern determination table for the first special symbol is composed of three types of tables: for the normal state (FIG. 26), for the short state at low base (FIG. 27), and for the short state at high base (FIG. 28).

[0223] In addition, the special symbol variation pattern determination table for the second special symbol is composed of two types of tables: one for the period from after the end of the jackpot until the 30th rotation ends in the high-base short state started with the jackpot (Fig. 29(a)), and the other for the entire period in the high-base short state started with a special loss or for the period after the 31st rotation in the high-base short state started with the jackpot (Fig. 29(b)).

[0224] Therefore, the special symbol variation pattern determination table of the gaming machine 1 is composed of five types of tables. All of these variation pattern determination tables are stored in the main ROM 120c.

[0225] In the special symbol variation pattern determination tables for the first special symbol in the normal state (Fig. 26), the first special symbol in the low-base short state (Fig. 27), and the second special symbol (Fig. 29), the special symbol, the hold number, the reach determination random value, the special symbol variation random value, the special symbol variation pattern, the special symbol variation time, and the variation pattern designation command are associated. Note that the variation pattern determination table shown for the first special symbol in the high-base short state (Fig. 28) is not associated with the hold number and the reach determination random value, and the special symbol, the special symbol variation random value, the special symbol variation pattern, the special symbol variation time, and the variation pattern designation command are associated.

[0226] The reach determination random value is a random value composed of 100 values with a random number range from 0 to 99. Since the reach effect is always performed in the case of a jackpot, the reach determination random value is not referenced in the case of the special symbol corresponding to the jackpot.

[0227] In addition, since the reach determination random value always triggers a reach effect during special losses in the normal state and the short state with a low base, and always causes a shortening variation during special losses in the short state with a high base, it is not referenced even in the case of special symbols corresponding to special losses. Therefore, the reach determination random value is only referenced in the case of special symbols corresponding to normal losses (special symbol y and special symbol z).

[0228] Hereinafter, the variation pattern determination table of the first special symbol referenced in the normal state will be described with reference to FIG. 26. In the variation pattern determination table of the first special symbol referenced in the normal state, in the case of the variation display where special symbol A (A per 10R of the first type) stops, according to the value of the special symbol variation random value, one of the variation patterns 10, 11, and 12 is associated.

[0229] The special symbol variation random value is a random value composed of 100 values with a random number range from 0 to 99. The allocation of the variation patterns for special symbol A increases in the order of variation pattern 12, variation pattern 11, and variation pattern 10. Also, the variation times T10, T11, and T12 for variation patterns 10, 11, and 12 are 20 seconds, 30 seconds, and 50 seconds respectively.

[0230] In the variation pattern determination table of the first special symbol referenced in the normal state, regarding the variation patterns and variation times of special symbol B (B per 2R of the first type), special symbol C (C per 2R of the first type), and special symbol D (D per 10R of the first type) when they stop, similar to the case of special symbol A, multiple types of variation patterns are associated according to the special symbol variation random value.

[0231] In the variation pattern determination table of the first special symbol referred to in the normal state, as the variation pattern when the special symbol a (special losing a) stops, variation pattern 30 and variation pattern 31 are associated according to the value of the random number value for special symbol variation. Also, regarding the variation patterns when the special symbol b (special losing b), the special symbol c (special losing c), and the special symbol d (special losing d) stop, similar to the special symbol a, two variation patterns are associated for each special symbol according to the value of the random number value for special symbol variation.

[0232] For variation pattern 30, variation pattern 32, variation pattern 34, and variation pattern 36 corresponding to special losing in the normal state, the variation time is all the same T30 (30 seconds). Also, for variation pattern 33, variation pattern 35, and variation pattern 37 corresponding to special losing in the normal state, the variation time is all the same T32 (40 seconds).

[0233] In the variation pattern determination table of the first special symbol referred to in the normal state, the variation pattern and variation time of the special symbol when the special symbol y (normal losing) stops are allocated according to the first special symbol retention count (U1), the reach determination random number value, and the random number value for special symbol variation.

[0234] Specifically, when the first special symbol retention count (U1) is 0 or 1, if the reach determination random number value is from 0 to 69, variation pattern 40 is associated, and if the reach determination random number value is from 70 to 99, one of variation patterns 41, 42, 43, 44 is associated according to the value of the random number value for special symbol variation. Similarly, when the first special symbol retention count is 2 or 3, if the reach determination random number value is from 0 to 89, variation pattern 45 is associated, and if the reach determination random number value is from 90 to 99, one of variation patterns 46, 47, 48, 49 is associated according to the value of the random number value for special symbol variation.

[0235] Note that although the maximum number of holds of the special symbol may be stored as 4, the variation pattern of the special symbol is determined after subtracting 1 from the number of holds of the special symbol. Therefore, when referring to the special symbol variation pattern determination table, since there is no situation where the number of holds is 4, the case where the number of holds is 4 is not included in the special symbol variation pattern determination table.

[0236] Note that the variation time T40 of variation pattern 40 is 4 seconds, and the variation time T44 of variation pattern 45 is 2 seconds. Therefore, the average time of the variation time of the special symbol when the normal loss stops is set longer when the first special symbol hold number (U1) is 0 or 1 than when it is 2 or 3. This is set in this way for two purposes: to make it easier to accumulate the hold number as the hold number decreases by setting the variation time longer as the hold number decreases, and to enable the high-speed digestion of the loss variation when the hold number is large and to make the game proceed smoothly.

[0237] Also, for variation patterns 42 and 47 in which the special symbol variation random value is selected from 50 to 69 when the special symbol y stops, the variation time is T30 (30 seconds) in both cases, which is the same as the variation time when variation patterns 30 (special symbol a), 32 (special symbol b), 34 (special symbol c), and 36 (special symbol d) corresponding to special losses stop. Although it will be described in detail later, in the case of the above variation patterns, since the same roulette effect is performed in all cases, the variation time is the same.

[0238] Next, the special symbol variation pattern determination table referred to in the low base short state using FIG. 27 will be described. Similar to the table referred to in the normal state, in the case of a big win and a special loss, the variation pattern is allocated according to the type of the special symbol and the value of the special symbol variation random value, and in the case of a normal loss, the variation pattern is allocated according to the hold number, the reach determination random value, and the special symbol variation random value. And in any case, the allocated variation pattern has a variation time and a variation pattern designation command associated with it.

[0239] The variation pattern determination table of the first special symbol, which is referred to in the normal state and the short low-base state, has the same number of variation patterns assigned to each special symbol except for the special symbol d, and the values assigned to the hold number, the random number value for reach determination, and the random number value for special symbol variation are also the same.

[0240] Note that for the special symbol d, in the normal state, two types of variation patterns can be determined by the random number value for special symbol variation, but in the short low-base state, one type of variation pattern is determined regardless of the random number for special symbol variation.

[0241] Also, when comparing the variation times of the variation pattern determination tables in the normal state and the short low-base state, for all variation patterns except variation pattern 31 (normal state) and variation pattern 64 (short low-base state) that become the random number value "20 to 99" for special symbol variation when the special symbol is special loss a, the variation times are the same.

[0242] Note that the variation time T31 of variation pattern 31, which becomes special loss a in the normal state, is 50 seconds, and the variation time T44 of variation pattern 64, which becomes special loss a in the short low-base state, is 35 seconds.

[0243] Next, the variation pattern determination table of the first special symbol, which is referred to in the short high-base state, will be described with reference to FIG. 28. As described above, the variation pattern determination table for the first special symbol in the short high-base state is not associated with the hold number and the random number value for reach determination, but is associated with the special symbol, the random number value for special symbol variation, the variation pattern of the special symbol, the variation time of the special symbol, and the variation pattern designation command.

[0244] In the variation pattern determination table of the first special symbol in the high-base short-time state, in the case of a big win, the variation patterns are allocated according to the type of special symbol and the random number value for special symbol variation. Also, in the case of a special loss and a normal loss in the high-base short-time state, one type of variation pattern is associated with each special symbol, and the same variation time T59 is associated with any of the variation patterns. Note that the variation time T59 is a shortened variation time of 2 seconds.

[0245] Next, the variation pattern determination table of the second special symbol will be described with reference to FIG. 29. FIG. 19(a) is a diagram showing the variation pattern determination table for the second special symbol variation, which is referred to in the period from after the end of the big win until the 30th rotation when the variation display is performed. In the variation pattern determination table of the second special symbol shown in FIG. 29(a), when the special symbol F (F for every 10R of the first type) and the special symbol G (G for every 2R of the first type) stop, similar to the variation pattern determination table of the first special symbol, a plurality of types of variation patterns are associated with each special symbol according to the value of the random number value for special symbol variation.

[0246] In the variation pattern determination table of the second special symbol shown in FIG. 29(a), when the special symbols H, I, and J corresponding to small wins stop, the variation patterns 210, 211, and 212 are respectively associated. Also, the variation patterns 210, 211, and 212 all have the same variation time of T55 (50 seconds).

[0247] In the variation pattern determination table of the second special symbol shown in FIG. 29(a), when the special symbol z, which is a normal loss, stops, the variation pattern and variation time of the special symbol are associated according to the second special symbol retention number (U2), the reach determination random number value, and the random number value for special symbol variation, similar to the case when the special symbol y (normal loss) in the variation pattern determination table of the first special symbol stops.

[0248] Also, when the special symbol z stops, the variation patterns 222 and 226 in which the random value for special symbol variation is selected from 40 to 89 both have a variation time of T55 (50 seconds), which is the same as the variation time when the variation patterns 210 (special symbol H), 211 (special symbol I), and 212 (special symbol J) corresponding to small wins stop. Although it will be described in detail later, in the case of the above variation patterns, the same chance effect is performed, so they have the same variation time.

[0249] FIG. 29(b) is a diagram showing a variation pattern determination table for the second special symbol variation that is referred to in periods other than when the variation display from the end of the big win to the 30th rotation is performed. Specifically, it is a diagram showing a variation pattern determination table for the second special symbol variation that is referred to in the high-base short state after the next variation after the special loss a is established in the normal state, and in the high-base short state after the 31st rotation after transitioning to the high-base short state after the end of the big win.

[0250] The variation pattern determination table for the second special symbol variation shown in FIG. 29(b) has fewer types of variation pattern designation commands than the variation pattern determination table for the second special symbol variation shown in FIG. 29(a). Specifically, in FIG. 29(a), there are many cases where a plurality of variation pattern designation commands are allocated to one type of special symbol according to the value of the random value for special symbol variation, but in FIG. 29(b), only one type of variation pattern designation command is associated with special symbols other than the special symbol z.

[0251] In addition, the variation time of the jackpot variation selected in FIG. 29(b) is set to be shorter than the variation time of the jackpot variation selected in FIG. 29(a). Specifically, the variation times selected by the special symbol F in FIG. 29(a) are T52 (60 seconds), T51 (40 seconds), and T50 (20 seconds), whereas the variation time selected by the special symbol F in FIG. 29(b) is T60 (5 seconds). Also, for the special symbol G, the special symbol H, the special symbol I, and the special symbol J, the variation time selected in FIG. 29(b) is shorter than each of the variation times selected in FIG. 29(a), similar to the special symbol F.

[0252] Furthermore, the variation time of the losing variation selected in FIG. 29(b) is set to be shorter than the variation time of the losing variation selected in FIG. 29(a). Specifically, the variation times selected by the special symbol z, which is a normal loss in FIG. 29(a), are T58 (60 seconds), T55 (50 seconds), T57 (20 seconds), T56 (6 seconds), and T59 (3 seconds). On the other hand, the variation times selected by the special symbol z, which is a normal loss in FIG. 29(b), are T61 (2 seconds) and T62 (1 second).

[0253] From the above, for the variation time of the second special symbol, it is easier to select a shorter variation time from the variation pattern determination table in FIG. 29(b) than from the variation pattern determination table in FIG. 29(a). That is, the variation time of the second special symbol is set to be shorter for the variation display after the variation display following the establishment of the special loss a and for the variation display after the 31st rotation after the end of the jackpot than for the variation display up to the 30th rotation after the end of the jackpot.

[0254] Therefore, after the next variable display when the special loss a is established, and in the high-base short state after the 31st rotation after the jackpot ends, the progress of the game becomes faster compared to the high-base short state from the end of the jackpot to the 30th rotation. Although details will be described later, in the high-base short state, three different types of production modes are executed according to the periods of "after the next variable display when the special loss a is established", "after the 31st rotation after the jackpot ends", and "from the end of the jackpot to the 30th rotation".

[0255] Although details will be described later, the main CPU 110a refers to the variable pattern determination table of the special symbol shown in FIG. 26, FIG. 27, FIG. 28, or FIG. 29, and based on the type of the special symbol display, the type of the special symbol, the number of reserved special symbols, the random number value for reach determination, and the random number value for special symbol variation, determines the variable pattern of the special symbol, the variable time of the special symbol, and the variable pattern designation command.

[0256] Also, although details will be described later, the production control board 120 controls the game production based on the variable pattern designation command received from the main control board 110. In the production content of FIG. 26, FIG. 27, FIG. 28, or FIG. 29, an example of the production executed by the production control board 120 according to each variable pattern designation command is described.

[0257] The following describes each production content described in the production content of FIG. 26, FIG. 27, FIG. 28, or FIG. 29. "Reach" refers to a variable state in which after all the decorative symbols 36 are variably displayed, the same type of decorative symbols temporarily stop on the left symbol 36L and the right symbol 36R, and the variation of the middle symbol 36C that has not temporarily stopped continues. And when the finally temporarily stopped middle symbol 36C is the same type as the previously temporarily stopped left symbol 36L and right symbol 36R, it becomes a combination of decorative symbols 36 indicating a jackpot. Also, when the finally temporarily stopped middle symbol 36C is a different type from the previously temporarily stopped left symbol 36L and right symbol 36R, it becomes a combination of decorative symbols 36 indicating a loss.

[0258] "Normal Variation" and "Shortened Variation" refer to variations in which, while multiple decorative symbols 36 are in motion, they do not reach a winning combination and instead stop losing with various types of decorative symbols 36. Also, the "Normal Variation" has a longer variation time than the "Shortened Variation".

[0259] However, if the combination of decorative symbols 36 that results in a loss is a specific combination, it may also be considered a combination of decorative symbols 36 indicating a specific jackpot (for example, "0", "0", "7", etc.). Also, by temporarily stopping a type of decorative symbol 36 that indicates a specific jackpot in the middle symbol 36C during a reach loss, it may be made into a combination of decorative symbols 36 indicating a specific jackpot (for example, "1", "2R win", "1", etc.).

[0260] "Normal Reach" is a reach effect with a low jackpot expectation in which the middle symbol 36C varies while the left symbol 36L and right symbol 36R of the same type are in a temporarily stopped state. "SP Reach" is a reach with a higher jackpot expectation than a Normal Reach, and is an effect that stimulates which type of decorative symbol 36 will temporarily stop on the middle symbol 36C using characters, etc. on a background different from that of a Normal Reach. "Full Rotation Reach" is a reach in which the jackpot is determined, and is a reach in which three decorative symbols 36 of the same type are combined and vary at a low speed.

[0261] "Roulette Effect" is an effect that is executed after a combination of decorative symbols 36 indicating a reach loss (for example, "3", "2", "3") is temporarily stopped, and is an effect indicating a change or continuation of the effect mode.

[0262] As shown in FIGS. 26 and 27, the roulette effect is an effect that is executed when the first special symbol is a special loss or a part of a normal loss. The outcomes that make up the roulette effect are three types of images corresponding to the "ground mode", "sea mode", and "undersea temple mode". Details will be described later, but the image corresponding to the "ground mode" is an image with the word "ground" attached, the image corresponding to the "sea mode" is an image with the word "sea" attached, and the image corresponding to the "undersea temple mode" is an image with the word "temple" attached.

[0263] According to the flow of the game flow described above, the roulette effect notifies the change or continuation of the effect mode according to the final outcome of the roulette corresponding to the decision. Note that the roulette effect is an effect that is executed only when the variable display of the first special symbol in the sea mode is performed, and is not executed when the variable display of the second special symbol is performed.

[0264] When the change of the mode effect is indicated by the roulette effect, the background image is switched to the background image corresponding to the destination mode. When the continuation of the mode effect is indicated by the roulette effect, the displayed background image is maintained, or the display is switched to another background image within the same mode (for example, in the sea mode, the background image is switched from the "shallow water background image" to the "deep sea background image", etc.).

[0265] The "battle effect" is an effect that notifies the establishment of a big win, the transition or continuation of the effect mode, by displaying the result of the battle (win, loss, draw), and is an effect that can be executed only when the effect mode is the sea mode.

[0266] The victory effect of the battle is executed when the first type 2R win C or the special loss a is established in the sea mode in the normal state, and when the first type 10R win D is established in the sea mode in the low base short state and the normal state. In any case, the game state transitions to the high base short state.

[0267] The battle loss effect is executed when special miss b, special miss c, or special miss d occurs in the sea mode in the normal state (when the game state transitions to the low base short state). Also, the battle loss effect is executed when some special misses occur in the sea mode in the low base short state (when the game state maintains the low base short state).

[0268] The battle draw effect is executed when a first type 10R hit A, a first type 2R hit B, or a normal miss occurs in the sea mode in the normal state (when the game state maintains the normal state). Also, the battle draw effect is executed when some special misses occur in the sea mode in the low base short state (when the game state maintains the low base short state). The details of the battle effect will be described later.

[0269] The "chance effect" is an effect executed after the symbol combination (e.g., "5", "4", "5") of the decorative symbol 36 indicating a reach miss is temporarily stopped, and is an effect indicating a small win or a reach miss.

[0270] The chance effect is executed when the second special symbol is a small win or a part of a normal miss. Note that the chance effect is executed only when the second special symbol is in variable display, and is not executed when the first special symbol is in variable display.

[0271] In the chance effect, one of the three types of images, "hit for 9R", "hit for 2R", and "miss", is displayed. Specifically, the chance effect is an effect in which one of the above three types of images appears from a treasure box image imitating a treasure box, and the winning result is notified according to the appeared image.

[0272] The image that appears from the treasure box image is an image of "hit for 9R" when the second special symbol is the second type 9R hit H or the second type 9R hit J, an image of "hit for 2R" when the second special symbol is the second type 2R hit I, and an image of "miss" when the second special symbol is a normal miss.

[0273] The treasure chest image is composed of three types of images with different designs, and the jackpot expectation degree varies according to the type of treasure chest image. In the case of a poor-looking treasure chest, a losing image is likely to appear. In the case of a normal treasure chest, the three types appear evenly. In the case of a luxurious treasure chest, an image with a 9R hit or a 2R hit is likely to appear.

[0274] The "instant win effect" is an effect in which the left symbol 36L, the right symbol 36R, and the middle symbol 36C stop in order at high speed without performing an effect that stirs whether it will be a jackpot by a reach effect, and the jackpot symbols are aligned. In the case of the first type of jackpot (special symbol F, special symbol J), a combination of decorative symbols 36 of the same symbol stops and is displayed. In the case of the second type of jackpot (special symbol H, special symbol I, special symbol J), after the same decorative symbol 36 stops and is displayed on the left symbol 36L and the right symbol 36R, a special symbol ("V hit") indicating a small win is stopped and displayed on the middle symbol 36C.

[0275] As described above, after the end of the special game of the second type 9R hit H, the game state becomes a high base short state, and after the end of the special game of the second type 9R hit J, it becomes the normal state. When a notification image notifying the second type 9R hit is displayed in the chance effect, it is difficult to identify which second type 9R hit has been won, and the effect during the jackpot notifies which hit it is. The details of the effect during the jackpot that notifies which jackpot it is will be described later.

[0276] Specifically, as will be described later using a flowchart, during a small win game that triggers a transition to the special symbols H, I, and J in the high base short state, if the game ball does not pass through the specific area 19B of the second large winning opening 17, the game state after the end of the small win game transitions from the high base short state to the normal state.

[0277] (Pre-judgment table for jackpot lottery) Figs. 30 and 31 are diagrams showing a preliminary determination table referred to for preliminarily determining the result of the jackpot lottery of the gaming machine 1. Fig. 30 is a diagram showing the preliminary determination table for the jackpot lottery in the first special symbol. Fig. 31 is a diagram showing the preliminary determination table for the jackpot lottery in the second special symbol.

[0278] Specifically, Fig. 31(a) is a diagram showing the preliminary determination table for the jackpot lottery in the second special symbol, which is referred to during the period when the variable display is performed from the end of the jackpot to the 30th rotation. Fig. 31(b) is a diagram showing the preliminary determination table for the jackpot lottery in the second special symbol, which is referred to during the variable display after the next variable display when the special loss a is established and during the variable display after the 31st rotation from the end of the jackpot.

[0279] As shown in Figs. 30 and 31, in the preliminary determination table for the jackpot lottery, a special symbol random value, a reach determination random value, a special symbol variation random value, winning information, and a start winning designation command are associated with each other.

[0280] Although it will be described in detail later, when a game ball wins a prize at the first start port 14 or the second start port 15, a special symbol random value, a reach determination random value, and a special symbol variation random value for the said prize are acquired. By using each of these acquired random values and the preliminary determination table for the jackpot lottery, it becomes possible to determine the lottery result of the variable display based on the said prize before the variable display based on the said prize is started.

[0281] The preliminary determination table for the jackpot lottery shown in Figs. 30 and 31 and the special symbol variation pattern determination table shown in Fig. 26, Fig. 27, or Fig. 29 are similar tables. However, the preliminary determination table for the jackpot lottery is referred to when a game ball wins a prize at the start port, whereas the special symbol variation pattern determination table is different in that it is referred to when the special symbol variation starts.

[0282] The common part between the pre-judgment table in the jackpot lottery and the special symbol variation pattern determination table is the allocation of variation patterns for jackpot, minor win, and special loss lottery results. Therefore, for variations resulting in jackpot, minor win, and special loss, the planned variation patterns and production contents can be grasped at the pre-judgment stage, enabling the performance of productions (preview productions) for the planned variations before the start of the variation display. Note that the preview production will be described later.

[0283] The different part between the pre-judgment table in the jackpot lottery and the special symbol variation pattern determination table is the allocation of variation patterns for normal loss. Specifically, in the pre-judgment table in the jackpot lottery, there is no allocation of variation patterns according to the number of holdovers, while in the special symbol variation pattern determination table, there is an allocation of variation patterns according to the number of holdovers.

[0284] Specifically, the allocation of reach determination random values for normal loss in FIG. 30 (“0 to 89” “90 to 99”) is different from the allocation of reach determination random values for normal loss (number of holdovers “0, 1”) in FIGS. 26 and 27 (“0 to 69” “70 to 99”), and is the same as the allocation of reach determination random values for normal loss (number of holdovers “2, 3”) in FIGS. 26 and 27 (“0 to 89” “90 to 99”).

[0285] That is, even when the first special symbol is a normal loss, when the reach determination random value is “70 to 89”, there are cases where it becomes a reach loss (number of holdovers “0, 1”) and non-reach loss (number of holdovers “2, 3”) according to the number of holdovers at the start of the variation. At the pre-judgment stage, it is impossible to grasp the number of holdovers at the start of the variation. Therefore, in the pre-judgment, only the reach determination random value “90 to 99” for which a reach is made regardless of the number of holdovers is pre-judged as a reach variation production.

[0286] Therefore, when the first special symbol is a normal loss, if the reach determination random value is "90 to 99", it is possible to perform a prediction effect that determines a reach. However, if the reach determination random value is "70 to 89", it is not possible to perform a prediction effect that determines a reach, and only a prediction effect that makes a reach more likely can be executed.

[0287] Also, similarly, since the number of holds at the start of the variation cannot be grasped at the pre-determination stage, when the first special symbol is a normal loss and the reach determination random value is "0 to 69", it is also impossible to pre-grasp whether a normal variation or a shortened variation will be performed. Note that in the case of a normal loss in the second special symbol, there may be a situation similar to the case of the normal loss in the first special symbol described above.

[0288] (Display screen in the image display device) Next, in order to explain the prediction effect, leaving the explanation of the table stored in the main ROM 110c, the outline of the screen displayed on the image display device 31 will be explained using FIG. 32.

[0289] FIG. 32 is a diagram showing an example of a display screen displayed on the image display device 31 of the gaming machine 1. The decorative symbol 36 is composed of a left symbol 36L, a middle symbol 36C, a right symbol 36R, and a fourth symbol 36Z. The left symbol 36L, the middle symbol 36C, and the right symbol 36R are displayed in the center of the display screen. The fourth symbol 36Z is displayed in the lower left of the display screen.

[0290] At the lower center of the image display device 31, a variable image 40 corresponding to the currently ongoing variation is displayed. On the left side of the variable image 40, a first hold image 41(1) of the first special symbol's first hold (the hold with the first waiting for variation) and a first hold image 41(2) of the first special symbol's second hold (the hold with the second waiting for variation) are displayed. When the number of holds of the first special symbol is the maximum value of 4, a first hold image 41(3) of the first special symbol's third hold (the hold with the third waiting for variation) and a first hold image 41(4) of the first special symbol's fourth hold (the hold with the fourth waiting for variation) are displayed on the left side of the first hold image (2).

[0291] On the right side of the variable image 40, a second hold image 42(1) of the first hold (the hold with the first waiting for variation) of the second special symbol is displayed. When the number of holds of the second special symbol is the maximum value of 4, a second hold image 42(2) of the second special symbol's second hold (the hold with the second waiting for variation), a second hold image 42(3) of the second special symbol's third hold (the hold with the third waiting for variation), and a second hold image 42(4) of the second special symbol's fourth hold (the hold with the fourth waiting for variation) are displayed on the right side of the second hold image (1).

[0292] At the lower left of the image display device 31, a fourth symbol 36Z, a first hold number image 43, and a second hold number image 44 are displayed. The first hold number image indicates the number of holds of the first special symbol in numbers. The second hold number image indicates the number of holds of the second special symbol in numbers. The number of images of the first hold image 41 is the same as the number indicated by the first hold number image 43, and the number of images of the second hold image 42 is the same as the number indicated by the second hold number image 44.

[0293] When the number of holds of the first special symbol increases due to the winning of a game ball in the first start port 14, a first hold image 41 and a first hold number image 43 corresponding to the number of holds after the increase are displayed. When the number of holds of the second special symbol increases due to the winning of a game ball in the second start port 15, a second hold image 42 and a second hold number image 44 corresponding to the number of holds after the increase are displayed.

[0294] When the number of holds of the first special symbol decreases due to the start of the variation of the first special symbol, the first hold image 41 and the first hold digit image 43 corresponding to the number of holds after the decrease are displayed. When the number of holds of the second special symbol decreases due to the start of the variation of the second special symbol, the second hold image 42 and the second hold digit image 44 corresponding to the number of holds after the decrease are displayed.

[0295] Note that the display change of the first hold image 41 according to the increase / decrease of the number of holds of the first special symbol is a change effect accompanied by an animation for a predetermined time, whereas the display change of the first hold digit image 43 is a change effect not accompanied by an animation shorter than the predetermined time.

[0296] Therefore, the execution time of the display change effect of the first hold image 41 according to the increase / decrease of the number of holds of the first special symbol is longer than the execution time of the display change effect of the first hold digit image 43 according to the increase / decrease of the number of holds of the first special symbol. Similarly, the execution time of the display change effect of the second hold image 42 according to the increase / decrease of the number of holds of the second special symbol is longer than the execution time of the display change effect of the second hold digit image 44 according to the increase / decrease of the number of holds of the second special symbol.

[0297] The variation image 40 becomes non-displayed when the variation display of the first special symbol ends. The first hold image 41(1) moves and is displayed at the position where the variation image 40 was displayed and changes to the variation image 40 as the variation image 40 becomes non-displayed. The first hold image 41(2) moves and is displayed at the position where the first hold image 41(1) was displayed and changes to the first hold image 41(1) as the first hold image 41(1) moves and is displayed. Note that for the second hold image 42 as well, when the variation display of the second special symbol ends, the same movement display and display change as those of the first hold image 41 are performed.

[0298] The first hold image 41 is composed of images of a plurality of colors (white, blue, yellow, green, red, rainbow) of the same design. The first hold image 41 indicates the jackpot expectation level for the variable display of the hold according to the display color. The jackpot expectation level of the first hold image 41 according to the display color increases in the order of rainbow, red, green, yellow, blue, white. Also, the display color of the first hold image 41 can only be changed to a display color with a higher jackpot expectation level than the current display color.

[0299] The display color of the first hold image 41 to be displayed is determined based on the above-mentioned preliminary determination of the jackpot lottery. Thus, the effect performed based on the preliminary determination of the jackpot lottery will hereinafter be described as the "preview effect". Also, among the preview effects, those that change the display color etc. of the first hold image 41 and the second hold image 42 will hereinafter be described as the "preview hold change effect".

[0300] In the preview hold change effect, only when the variable display scheduled for the hold is a reach variation according to the preliminary determination, the first hold image 41 with the display colors of rainbow, red, and green can be displayed. On the other hand, the first hold image 41 with the display colors of yellow, blue, and white is displayed whether it is a reach variation or a non-reach variation.

[0301] As described above, the preview effect is performed to suggest the possibility of a jackpot in the variable display of the hold to be previewed, but it may also be performed to suggest the possibility of a specific loss occurring. Specifically, based on the fact that the establishment of the special loss a in the normal state is determined by the preliminary determination of the jackpot lottery, the preview effect may be performed.

[0302] Also, without being based on the preliminary determination of the jackpot lottery, a preview effect may be performed according to the remaining number of times of the low base short number of times (B). Although it will be described in detail later, the gaming machine 1 suggests the transition of the gaming state to the normal state in the low base short state by executing a specific effect mode, but it may also be performed by the preview effect.

[0303] (Normal symbol determination table) Returning again to the description of the tables stored in the main ROM 110c. FIG. 33 is a diagram showing various determination tables for the normal symbols of the gaming machine 1. FIG. 33(a) is a diagram showing the normal symbol determination table of the gaming machine 1. In the normal symbol determination table, the game state, the win / loss determination result, the type of normal symbol, the stop symbol data, and the normal symbol designation command are associated with each other.

[0304] Based on the hit lottery determination table shown in FIG. 18(c), the win / loss determination result determined based on the normal symbol random value, and the current game state, the main CPU 110a refers to the normal symbol determination table and determines the normal symbol and the stop symbol data. The main CPU 110a determines a normal symbol designation command based on the determined normal symbol and stop symbol data, and transmits the determined normal symbol designation command to the effect control board 120.

[0305] FIG. 33(b) is a diagram showing the variation pattern determination table of the normal symbol. In the variation pattern determination table of the normal symbol, the game state, the win / loss determination result, the variation pattern of the normal symbol, the variation time, and the normal symbol variation designation command are associated with each other. Note that in each game state, the variation time is the same both in the case of a hit determination and in the case of a miss determination, but the variation time may be made different according to the win / loss determination.

[0306] Based on the hit lottery determination table shown in FIG. 18(c), the win / loss determination result determined based on the normal symbol random value, and the current game state, the main CPU 110a refers to the variation pattern determination table of the normal symbol shown in FIG. 33(b) and determines the variation pattern of the normal symbol. The main CPU 110a determines a normal symbol variation designation command based on the determined variation pattern of the normal symbol, and transmits the determined normal symbol designation command to the effect control board 120.

[0307] (Auxiliary game control table) FIG. 34 is a diagram showing the auxiliary game table of the gaming machine 1. FIG. 34(a) is a diagram showing the auxiliary game control table. In the auxiliary game control table, a game state, stop symbol data, an opening time, a table number of the movable piece opening / closing control table for auxiliary games, and an ending time are associated with each other.

[0308] Based on the stop symbol data, the main CPU 110a refers to the auxiliary game control table to determine the opening time, the table number of the movable piece control table for auxiliary games, and the ending time.

[0309] (Movable piece opening / closing control table for auxiliary games) FIG. 34(b) is a diagram showing the movable piece opening / closing control table for auxiliary games. In the movable piece opening / closing control table for auxiliary games, the table number of the movable piece control table for auxiliary games, the number of times the movable piece 15b opens, the opening time of the movable piece 15b, and the closing time of the movable piece 15b are associated with each other.

[0310] Based on the table number of the movable piece control table for auxiliary games, the main CPU 110a refers to the movable piece opening / closing control table for auxiliary games to determine the number of times the movable piece 15b opens, the opening time of the movable piece 15b, and the closing time of the movable piece 15b.

[0311] (Various memory areas) FIG. 35 is a diagram showing various memory areas set in the main RAM 110b of the gaming machine 1. FIG. 35(a) is a diagram showing the special symbol memory area. The special symbol memory area has a 0th memory unit corresponding to the variation, a 1st special symbol memory area in which determination information obtained when a game ball enters the 1st start port 14 is stored, and a 2nd special symbol memory area in which determination information obtained when a game ball enters the 2nd start port 15 is stored.

[0312] The first special symbol storage area has a first storage unit corresponding to the first hold, a second storage unit corresponding to the second hold, a third storage unit corresponding to the third hold, and a fourth storage unit corresponding to the fourth hold. Similarly, the second special symbol storage area has a first storage unit corresponding to the first hold, a second storage unit corresponding to the second hold, a third storage unit corresponding to the third hold, and a fourth storage unit corresponding to the fourth hold.

[0313] Note that the number of pieces of determination information stored in the first to fourth storage units of the first special symbol storage area is the first special symbol hold number (U1), and the number of pieces of determination information stored in the first to fourth storage units of the second special symbol storage area is the second special symbol hold number (U2).

[0314] Fig. 35(b) is a diagram showing each storage unit of the special symbol storage area. As shown in Fig. 35(b), in each storage unit of the first special symbol storage area and the second special symbol storage area, areas for storing jackpot random values, special symbol random values, special symbol variation random values, and reach determination random values are provided.

[0315] When a game ball enters the first start port 14 and determination information is acquired, the acquired determination information is stored in the storage unit with the smallest number among the first to fourth storage units of the first special symbol storage area where the determination information is not stored. Similarly, when a game ball enters the second start port 15 and determination information is acquired, the acquired determination information is stored in the storage unit with the smallest number among the first to fourth storage units of the second special symbol storage area where the determination information is not stored.

[0316] When the start condition for the variable display of the first special symbol is satisfied in the 0th storage unit of the special symbol storage area, the determination information stored in the first storage unit of the first special symbol storage area is shifted. Similarly, when the start condition for the variable display of the second special symbol is satisfied in the 0th storage unit of the special symbol storage area, the determination information stored in the first storage unit of the second special symbol storage area is shifted. Then, when performing the variable display of the special symbol for which the start condition is satisfied, the determination information shifted to the 0th storage unit is referred to for performing the variable display of the special symbol.

[0317] FIG. 35(c) is a diagram showing the normal symbol determination area. The normal symbol storage area has a 0th storage unit corresponding to the variation, a 1st storage unit corresponding to the 1st hold, a 2nd storage unit corresponding to the 2nd hold, a 3rd storage unit corresponding to the 3rd hold, and a 4th storage unit corresponding to the 4th hold.

[0318] FIG. 35(d) is a diagram showing each storage unit of the normal symbol storage area. As shown in FIG. 35(d), an area for storing normal symbol random values is provided in each storage unit of the normal symbol storage area. Since there is one type of variation pattern of the normal symbol for each pass / fail determination result in each gaming state, no normal symbol variation random value for distributing the variation patterns of the normal symbol is provided.

[0319] When a game ball passes through the normal symbol gate 13 and a normal symbol random value is acquired, the acquired determination information is stored in the storage unit with the smallest number among the 1st to 4th storage units of the normal symbol storage area where the determination information is not stored.

[0320] When the start condition for the variation display of the normal symbol is satisfied in the 0th storage unit of the normal symbol storage area, the determination information stored in the 1st storage unit of the normal symbol storage area is shifted. And when performing the variation display of the normal symbol for which the start condition is satisfied, the determination information shifted to the 0th storage unit is referred to for performing the variation display of the normal symbol.

[0321] Next, the progress of the game performed by the main control board 110 in the gaming machine 1 will be specifically described using a flowchart.

[0322] (Main process of the main control board) FIG. 36 is a diagram showing a flowchart of the main process of the main control board 110 of the gaming machine 1. The main process starts when a system reset occurs in the main CPU 110a when power is supplied to the main control board 110 by the power supply board 175.

[0323] As shown in FIG. 36, in step S10, the main CPU 110a executes initialization processing. In the initialization processing, the main CPU 110a reads a game control program and game control data from the main ROM 110c into the main RAM 110b in response to power-on. Thereafter, the main CPU 110a determines whether to restore data based on the on / off state of the RAM clear SW 111a provided on the back surface of the gaming machine 1 at the time of power-on, and the power-off occurrence information and checksum content backed up in the power-off monitoring process (S30) at the time of the previous power-off. If it is determined to restore the data, the data in the main RAM 110b is restored. If it is determined not to restore the data, the main RAM 110b is cleared (RAM clear). Details of the initialization processing will be described later.

[0324] In step S20, the main CPU 110a executes game machine information notification processing. In the game machine information notification processing, the main CPU 110a generates a game machine information notification command for notifying the game state of the gaming machine 1 including the progress and stop status of the game to the frame control board 160, and transmits the generated game machine information notification command to the frame control board 160. Details of the game machine information notification processing of the main control board 110 will be described later.

[0325] Next, in step S30, the main CPU 110a executes power-off monitoring processing. In the power-off monitoring processing, the main CPU 110a monitors whether a power-off has occurred in the gaming machine 1. When a power-off occurs, the main CPU 110a transmits a firing prohibition command to the firing control unit 170, stops the energization of the firing solenoid 4a and the ball feed solenoid 4b to the firing CPU 170a, and stops the firing of the game ball. Further, the main CPU 110a clears the output port, creates and saves the checksum of the main RAM 110b, and sets the power-off occurrence information. After that, the main CPU 110a sets the access to the main RAM 110b to be prohibited to prepare for a power-off. Details of the power-off monitoring processing will be described later.

[0326] Next, the main CPU 110a performs a game random value update process in step S40. In the game random value update process, the main CPU 110a updates the reach determination random value and the special symbol variation random value. Next, the main CPU 110a performs an initial random value update process in step S50. In the initial random value update process, the main CPU 110a updates the jackpot initial random value, the normal symbol initial random value, and the special symbol initial random value.

[0327] The main CPU 110a repeats the loop process from step S20 to step S50 hereafter. During this loop process, the main CPU 110a executes a timer interrupt process described later by having a clock pulse generated every predetermined period (for example, 2 ms) by a reset clock pulse generation circuit provided on the main control board 110.

[0328] (Initialization Process of Main Control Board) FIGS. 37 and 38 are diagrams showing a flowchart of the initialization process of the gaming machine 1 in step S10 in FIG. 36.

[0329] In step S10-1, the main CPU 110a performs a security check of the main CPU 110a and waits for processing for 2000 ms.

[0330] In step S10-2, the main CPU 110a permits access to the main RAM 110b. Next, in step S10-3, the main CPU 110a sets the serial communication port.

[0331] Next, in step S10-4, the main CPU 110a sets a watchdog timer. The watchdog timer monitors whether the main control unit 110m of the main control board 110 is operating normally. The main CPU 110a periodically sends a signal indicating that it is operating normally to the watchdog timer, and the watchdog timer is cleared by receiving this signal. When the processing of the main control unit 110m has stopped or when an infinite loop process of a specific process is being performed, the watchdog timer counts up without clearing, and when the timer value reaches a predetermined count value, the main control unit 110m is reset.

[0332] Next, in step S10-5, the main CPU 110a transmits a power-on designated command to the effect control board 120 and the frame control board 160. Next, in step S10-6, the main CPU 110a transmits a firing permission command to the firing control unit 170.

[0333] Note that when the firing CPU 170a receives the firing permission command, it sets a firing permission flag in the firing permission flag storage area of the firing RAM 170b. When the firing permission flag is set in the firing permission flag storage area of the firing RAM 170b, the firing CPU 170 detects the inputs of the touch sensor 3a and the firing volume 3b, and controls the firing solenoid 4a and the ball feed solenoid 4b to enable the firing of the game ball.

[0334] Next, in step S10-7, the main CPU 110a determines whether the RAM clear SW 111a is on. If the RAM clear SW 111a is on, the main CPU 110a proceeds to step S10-14 (Figure 38). If the RAM clear SW 111a is off, the main CPU 110a proceeds to step S10-8.

[0335] Next, in step S10-8, the main CPU 110a determines whether the power-off occurrence information stored in the main RAM 110b is normal. If the power-off occurrence information is normal, the main CPU 110a proceeds to step S10-9; if the power-off occurrence information is not normal, the main CPU 110a proceeds to step S10-11.

[0336] Next, in step S10-9, the main CPU 110a calculates the checksum of the main RAM 110b. Next, in step S10-10, the main CPU 110a determines whether the calculated checksum is normal. If the calculated checksum is normal, the main CPU 110a proceeds to step S10-19; if the calculated checksum is not normal, the main CPU 110a proceeds to step S10-11.

[0337] Note that whether the calculated checksum is normal is determined to be normal when the checksum calculated at the previous power-off and stored in the main RAM 110b matches the newly calculated checksum in step S10-9, and is determined to be not normal when they do not match.

[0338] In step S10-11, the main CPU 110a sends an irrecoverable designation command to the effect control board 120. Note that when receiving the irrecoverable designation command, the effect control board 120 executes processing for displaying an irrecoverable notification on the image display device 31.

[0339] The "irrecoverable notification" is processing such as displaying an image notifying that the game cannot be recovered on the image display device 31, specific light emission of effect lighting devices such as the first effect lighting device 340a, and specific voice output by the voice output device 32 ("The game cannot be recovered. Please perform a RAM clear").

[0340] In step S10-12, the main CPU 110a sends a launch prohibition command to the launch control unit 170 to prohibit the launch of game balls.

[0341] In step S10-13, the main CPU 110a prohibits access to the main RAM 110b and then executes an infinite loop process.

[0342] In step S10-14, the main CPU 110a clears the used area of the main RAM 110b. Next, in step S10-15, the main CPU 110a configures the RAM when the backup is not valid. Next, in step S10-16, the main CPU 110a clears the watchdog timer.

[0343] Next, in step S10-17, the main CPU 110a sends a RAM clear designation command to the effect control board 120 and proceeds to step S10-18. When the effect control board 120 receives the RAM clear designation command, it executes a process for performing a RAM clear preparation notification.

[0344] The "RAM clear preparation notification" is a process such as displaying an image notifying that the RAM clear will be executed on the image display device 31, specific light emission of an effect lighting device such as the first effect lighting device 340a, or specific voice output ( "The RAM clear is in progress") from the voice output device 32.

[0345] Next, in step S10-18, the main CPU 110a performs initial settings for the devices around the CPU and proceeds to step S10-22. Specifically, the main CPU 110a sets the output settings to the effect control board 120, the settings of the CTC (counter Timer Circuit) to be used, and the interrupt timer (2ms) of the CTC to be used.

[0346] In step S10-19, the main CPU 110a configures the RAM when the backup is valid. Specifically, after clearing the backup flag and checksum stored in the main RAM 110b, the main CPU 110a restores the data in each used area of the main RAM 110b based on the power-off occurrence information.

[0347] The data restored based on the power-off occurrence information is data such as that stored in data storage areas such as the special symbol memory area, the special figure special power processing data memory area, the stop symbol data memory area, the normal symbol reservation memory area, the general figure general power processing data memory area, the normal symbol data memory area, the complete information memory area, the game state flag memory area, the specific area winning flag memory area, the game state buffer, the round number (R) counter, the big winning opening ball entry number (C) counter, the first special symbol reservation number (U1) counter, the second special symbol reservation number (U2) counter, the normal symbol reservation number (G) counter, the low base short time number (B) counter, the high base short time number (J) counter, the variation number (L) counter, the opening number (S) counter, the special power operation number (K) counter, the special symbol time counter, the special game timer counter, the normal symbol time counter, the auxiliary game timer counter, the game machine information transmission waiting timer counter, the response reception waiting timer counter, the communication failure determination counter, the maximum acquired game ball number counter, and the production transmission data storage area.

[0348] Next, in step S10-20, the main CPU 110a performs initial settings for the devices around the CPU. Specifically, it sets the output to the effect control board 120, the setting of the CTC (counter timer circuit) to be used, and the interrupt timer (2 ms) of the CTC to be used.

[0349] Next, in step S10-21, the main CPU 110a determines whether the game state stored in the game state flag memory area of the main RAM 110b is the normal state. When the game state stored in the game state flag memory area of the main RAM 110b is the normal state, the main CPU 110a proceeds to step S10-22. When the game state stored in the game state flag memory area of the main RAM 110b is not the normal state, the main CPU 110a proceeds to step S10-21.

[0350] In step S10-22, the main CPU 110a transmits a power recovery designation command corresponding to the normal state to the effect control board 120 and the frame control board 160, and proceeds to step S10-26. The reason why the process of step S10-22 is performed after step S10-18 is that the normal state is set in the game state flag storage area of the main RAM 110b in step S10-15.

[0351] In step S10-23, the main CPU 110a determines whether the game state stored in the game state flag storage area of the main RAM 110b is the short state at low base. If the game state stored in the game state flag storage area of the main RAM 110b is the short state at low base, the main CPU 110a proceeds to step S10-24; if the game state stored in the game state flag storage area of the main RAM 110b is not the short state at low base, the main CPU 110a proceeds to step S10-25.

[0352] In step S10-24, the main CPU 110a transmits a power recovery designation command corresponding to the short state at low base to the effect control board 120 and the frame control board 160, and proceeds to step S10-23.

[0353] In step S10-25, the main CPU 110a transmits a power recovery designation command corresponding to the short state at high base to the effect control board 120 and the frame control board 160, and proceeds to step S10-24.

[0354] In step S10-26, the main CPU 110a transmits a game state designation command corresponding to the game state after power recovery to the effect control board 120, and ends the initialization process.

[0355] In addition, when the power is turned off in the short low-base state among the five gaming states shown in FIG. 10, in the main control board 110, the gaming state flag of the short low-base state and the count value of the game ball counter are backed up in the gaming state flag storage area of the main RAM 110b, and in the game ball number control unit 180 of the frame control board 160, the gaming state flag of the short low-base state and the count value of the game ball counter are backed up in the gaming state flag storage area of the game ball number RAM 180b.

[0356] Further, when the normal power-on operation shown in FIG. 17(a) or the main control board RAM clear power-on operation shown in FIG. 17(b) is performed, in the initial setting process performed by the game ball number control unit 180 of the frame control board 160 described later, the game ball number recovery designation command for the recovered game ball number is transmitted to the main control board 110. However, when the frame control board RAM clear power-on operation shown in FIG. 17(c) or the all RAM clear power-on operation shown in FIG. 17(d) is performed, the game ball number recovery designation command is not transmitted to the main control board 110.

[0357] (Game machine information notification process of the main control board) FIG. 39 is a diagram showing the process of the game machine information notification process of the main control board 110 shown in step S20 of FIG. 36.

[0358] The main CPU 110a determines in step S20-1 whether the value of the game machine information transmission standby timer counter stored in the main RAM 110b is greater than 0. When the value of the game machine information transmission standby timer counter is greater than 0, the main CPU 110a proceeds to step S20-2, and when it is not greater than 0 (i.e., 0), the main CPU 110a proceeds to step S20-5.

[0359] The game machine information transmission standby timer counter is a counter used to measure 108 ms, which is the transmission cycle of the game machine information notification command from the main control board 110 to the frame control board 160 as shown in FIG. 13.

[0360] The update of the counter value of the game machine information transmission waiting timer counter is performed in the counter update process of the timer interrupt process of the main control board 110 described later. Specifically, the counter value of the game machine information transmission waiting timer counter is updated by subtracting 2 each time the timer update process in the timer interrupt process is executed every 2 ms and the counter update process in the timer interrupt process is performed once.

[0361] In step S20-2, the main CPU 110a determines whether or not a response command has been received from the frame control board 160. When the main CPU 110a has received a response command, the process proceeds to step S20-3, and when the main CPU 110a has not received a response command, the process proceeds to step S20-8.

[0362] In step S20-3, the main CPU 110a clears the communication failure determination counter in the main RAM 110b. The communication failure determination counter is a counter used to determine that no response command has been received from the frame control board 160 for the transmission of the game machine information notification command 10 times in a row.

[0363] In step S20-4, the main CPU 110a clears the response reception waiting timer counter in the main RAM 110b and proceeds to step S20-12.

[0364] In step S20-5, the main CPU 110a transmits a game machine information notification command to the frame control board 160. In step S20-6, the main CPU 110a sets "108" in the game machine information transmission waiting timer counter.

[0365] In step S20-7, the main CPU 110a sets the value "10" in the communication failure determination counter in the main RAM 110b and proceeds to step S20-11.

[0366] In step S20-8, main CPU 110a determines whether the value of the response reception standby timer counter in main RAM 110b is greater than 0. When the value of the response reception standby timer counter is greater than 0, main CPU 110a proceeds to step S20-12. When the value of the response reception standby timer counter is not greater than 0 (i.e., 0), main CPU 110a proceeds to step S20-9.

[0367] In step S20-9, main CPU 110a decrements the value of the communication failure determination counter in main RAM 110b by 1. In step S20-10, main CPU 110a determines whether the value of the communication failure determination counter in main RAM 110b is greater than 0. When the value of the communication failure determination counter is greater than 0, main CPU 110a proceeds to step S20-11. When the value of the communication failure determination counter is not greater than 0 (i.e., 0), main CPU 110a proceeds to step S20-14.

[0368] In step S20-11, main CPU 110a sets "10" in the response reception standby timer counter of main RAM 110b. The response reception standby timer counter is used to measure the 10 ms standby time for receiving a response command from frame control board 160 since the transmission of the current gaming machine information notification command.

[0369] The update of the counter value of the response reception standby timer counter is performed in the counter update process of the timer interrupt process of main control board 110 described later. Specifically, since the timer update process within the timer interrupt process is executed every 2 ms, the counter value of the response reception standby timer counter is updated by subtracting 2 each time the counter update process of the timer interrupt process is performed.

[0370] In step S20-12, main CPU 110a determines whether it has received a game ball number designation command from frame control board 160. When main CPU 110a has received the game ball number designation command, it proceeds to step S20-13. When it has not received the game ball number designation command, it ends the gaming machine information notification process.

[0371] The game ball number designation command, which will be described in detail later, is a command transmitted from the game ball number control unit 180 of the frame control board 160 to the main control unit 110 when the game ball number counter in the game ball number RAM 180b of the game ball number control unit 180 is updated.

[0372] In step S20-13, the main CPU 110a performs an update process of adding or subtracting the number of game balls indicated by the received game ball number designation command to / from the maximum acquired game ball number counter in the main RAM 110b, and then ends the game machine information notification process. Note that the value of the maximum acquired game ball number counter in the main RAM 110b updated by the above update process is a value different from the game ball number counter in the game ball number RAM 180b.

[0373] In step S20-14, the main CPU 110a transmits a communication failure command to the effect control board 120. When the effect control board 120 receives the communication failure command, it performs a process to cause the image display device 31 to display a communication failure occurrence notification.

[0374] In step S20-15, the main CPU 110a sets the interrupt prohibition. In step S20-16, the main CPU 110a transmits a firing prohibition command to the firing control unit 170. The firing control unit 170, which will be described in detail later, clears the firing permission flag when it receives the firing prohibition command and stops the energization to the firing solenoid 4a and the ball feed solenoid 4b.

[0375] In step S20-17, the main CPU 110a prohibits access to the main RAM 110b and then performs a standby process.

[0376] (Power-off monitoring process of the main control board) Figure 40 is a diagram showing a flowchart of the power-off monitoring process of the main control board 110.

[0377] In step S30-1, the main CPU 110a sets interrupt inhibition. Next, in step S30-2, the main CPU 110a determines whether a power-off of the gaming machine 1 has occurred. Specifically, when a power-off detection signal is input from a power-off detection circuit (not shown) provided on the power supply board 175, the main CPU 110a determines that a power-off has occurred.

[0378] If the main CPU 110a determines that a power-off has occurred, it proceeds to step S30-4. If it determines that a power-off has not occurred, it proceeds to step S30-3.

[0379] In step S30-3, the main CPU 110a sets interrupt permission and ends the power-off monitoring process.

[0380] In step S30-4, the main CPU 110a sends a firing inhibition command to the firing control unit 170. Next, in step S30-5, the main CPU 110a clears the output port. Next, in step S30-6, the main CPU 110a sends a power-off designation command to the firing control unit 170 and the game ball number control unit 180 of the frame control board 160.

[0381] In step S30-7, the main CPU 110a calculates a checksum of the data within the used area of the main RAM 110b and sets it in a predetermined area of the main RAM 110b.

[0382] Note that the data targeted when the main CPU 110a calculates the checksum includes data stored in data storage areas such as the special symbol storage area, the special drawing and special power processing data storage area, the stop symbol data storage area, the normal symbol reservation storage area, the normal drawing and normal power processing data storage area, the normal symbol data storage area, the complete information storage area, the game state flag storage area, the specific area winning flag storage area, the game state buffer, the round number (R) counter, the big winning opening ball entry number (C) counter, the first special symbol reservation number (U1) counter, the second special symbol reservation number (U2) counter, the normal symbol reservation number (G) counter, the low base short count (B) counter, the high base short count (J) counter, the variation count (L) counter, the open count (S) counter, the special power operation number (K) counter, the special symbol time counter, the special game timer counter, the normal symbol time counter, the auxiliary game timer counter, the game machine information transmission waiting timer counter, the response reception waiting timer counter, the communication failure determination counter, the maximum acquired game ball number counter, and the production transmission data storage area.

[0383] Next, in step S30-8, the main CPU 110a sets a backup flag to be referred to at the time of recovery from a power failure in a predetermined area of the main RAM 110b. Next, in step S30-9, the main CPU 110a prohibits access to the main RAM 110b. After that, the main CPU 110a performs an infinite loop process and waits until the supply of the power voltage completely disappears.

[0384] (Timer Interrupt Processing of the Main Control Board) FIG. 41 is a diagram showing a flowchart of the timer interrupt processing of the main control board 110 of the gaming machine 1. The main CPU 110a executes timer interrupt processing at each generation cycle (for example, 2 ms) in which a clock pulse signal is generated by a reset clock pulse generation circuit provided in the main control board 110, except for special cases such as when the power is turned on or off.

[0385] When the clock pulse signal is generated, in step S100, the main CPU 110a saves the information stored in the register of the main CPU 110a in the stack area.

[0386] Next, in step S110, the main CPU 110a performs counter update processing. Specifically, the main CPU 110a updates the special symbol time counter, special game timer counter, normal symbol time counter, sub-game timer counter, game machine information transmission waiting timer counter, and response reception waiting timer counter stored in the main RAM 110b. In the counter update processing, each counter is decremented by 2. The reason for decrementing each counter by 2 in the counter update processing is that these counters are counters indicating time, and since the timer interrupt processing is executed every 2 ms, the counter update processing within the timer interrupt processing is performed every 2 ms.

[0387] The special symbol time counter is a counter used when the main CPU 110a determines whether the variation of the special symbol has elapsed the variation time or whether the stop of the special symbol has elapsed the stop time. The special game timer counter is a counter used when the main CPU 110a controls the opening and closing of the first big winning port 16 and the second big winning port 17. The normal symbol time counter is a counter used when determining whether the variation of the normal symbol has elapsed the variation time or whether the stop of the normal symbol has elapsed the stop time. The sub-game timer counter is a counter used when the main CPU 110a controls the opening and closing of the second start port 15. Details of the control using each of these counters will be described later.

[0388] As described in the game machine information notification processing of the main control board 110 shown in FIG. 39, the game machine information transmission waiting timer counter is a counter used when the main CPU 110a transmits a game machine information notification command from the main control board 110 to the frame control board 160. Also, the response reception waiting timer counter is a counter used when the main CPU 110a determines whether the communication between the main control board 110 and the frame control board 160 is being performed normally.

[0389] Next, in step S120, the main CPU 110a updates the jackpot random value, the normal symbol random value, and the special symbol random value. Specifically, the main CPU 110a adds 1 to each random value and the random counter. When the added random counter exceeds the maximum value of the random range (when the random counter makes one full cycle), the main CPU 110a resets the random counter to 0 and newly updates each random value from the initial random value at that time.

[0390] Next, in step S130, the main CPU 110a performs initial random value update processing. Specifically, the main CPU 110a updates the jackpot initial random value, the normal symbol random value, and the special symbol initial random value.

[0391] Next, in step S200, the main CPU 110a performs input control processing. Specifically, the main CPU 110a determines whether there is an input to each of the SWs of the general winning opening detection SW12a, the gate detection SW13a, the first start opening detection SW14a, the second start opening detection SW15a, the first big winning opening detection SW16a, the second big winning opening detection SW17a, and the specific area detection SW18a, and executes predetermined processing when there is an input. Details of the input control processing will be described later.

[0392] Next, in step S300, the main CPU 110a executes special figure and special electric control processing. Specifically, the main CPU 110a updates the value of the special figure and special electric processing data stored in the main RAM 110b according to the progress of the game, and executes predetermined processing based on the updated value of the special figure and special electric processing data. Details of the special figure and special electric control processing will be described later.

[0393] Next, in step S400, the main CPU 110a executes normal figure and normal electric control processing. Specifically, the main CPU 110a updates the value of the normal figure and normal electric processing data stored in the main RAM 110b according to the progress of the game, and executes predetermined processing based on the updated value of the normal figure and normal electric processing data. Details of the normal figure and normal electric control processing will be described later.

[0394] Next, in step S500, main CPU 110a executes prize ball control processing. Specifically, main CPU 110a refers to the general winning opening prize ball counter, the first start opening prize ball counter, the second start opening prize ball counter, the first big winning opening prize ball counter, and the second big winning opening prize ball counter stored in main RAM 110b, and transmits a prize ball number designation command for instructing the awarding of the number of game balls indicated by each counter to frame control board 160.

[0395] Next, in step S600, main CPU 110a executes complete determination processing. The complete determination processing is a process for determining whether or not to activate a function (complete function) that restricts the execution of further games when the maximum number of acquired game balls in gaming machine 1 exceeds the upper limit value of 95,000 for one day.

[0396] Specifically, main CPU 110a determines whether or not the maximum acquired game ball number counter in main RAM 110b exceeds 95,000. When the maximum acquired game ball number counter exceeds 95,000, main CPU 110a stores complete information in the complete information storage area of main RAM 110b, stores an error system designation command indicating error 1 in the production transmission data storage area, and sets a firing prohibition command for stopping the firing of game balls in transmission buffer to firing control unit 170.

[0397] Note that the maximum acquired game ball number counter is a counter that adds the number indicated by each prize ball counter when there is an awarding of game balls, and subtracts 1 when there is a firing of game balls when the counter value is 1 or more, and has a minimum value of 0.

[0398] Next, the main CPU 110a executes data generation processing in step S700. Specifically, the main CPU 110a performs processing to create drive data for the start port opening / closing solenoid 15c, drive data for the first large winning port opening / closing solenoid 16c, drive data for the second large winning port opening / closing solenoid 17c, drive data for the specific area opening / closing solenoid 18d, display data for the first special symbol display device 20, display data for the second special symbol display device 21, display data for the normal symbol display device 24, display data for the first special symbol hold display 22, display data for the second special symbol display 23, and display data for the normal symbol hold display 25.

[0399] Next, the main CPU 110a executes output control processing in step S800. Specifically, the main CPU 110a outputs each display data, each drive data, and the external information signal generated in the data generation processing of step S700. Further, the main CPU 110a also executes processing for transmitting commands set in the production transmission data storage area and the transmission buffer of the main RAM 110b to the production control board 120 and the frame control board 160.

[0400] Next, in step S900, the main CPU 110a restores the information saved in the stack area in step S100 to the registers of the main CPU 110a and ends the timer interrupt processing.

[0401] (Input Control Processing of the Main Control Board) FIG. 42 is a diagram showing a flowchart of the input control processing of the main control board 110 of the gaming machine 1.

[0402] In step S210, main CPU 110a executes general winning port detection SW input processing. Specifically, main CPU 110a determines whether there is a detection signal from general winning port detection SW 12a. When there is a detection signal from general winning port detection SW 12a, main CPU 110a performs an update process of adding a predetermined number (for example, 1) to the general winning port prize ball counter stored in main RAM 110b, and proceeds to step S220 for processing. When there is no detection signal from general winning port detection SW 12a, main CPU 110a directly proceeds to step S220 for processing.

[0403] In step S220, main CPU 110a executes big winning port detection SW input processing. Specifically, main CPU 110a determines whether there is a detection signal from first big winning port detection SW 16a or second big winning port detection SW 17a. When there is a detection signal from first big winning port detection SW 16a or second big winning port detection SW 17a, main CPU 110a increments the big winning port ball entry number (C) counter stored in main RAM 110b by 1, and proceeds to step S230 for processing. When there is no detection signal from first big winning port detection SW 16a or second big winning port detection SW 17a, main CPU 110a directly proceeds to step S230 for processing.

[0404] Next, in step S230, main CPU 110a executes first start port detection SW input processing. Specifically, main CPU 110a determines whether there is an input of a detection signal from first start port detection SW 14a. When there is no input of a detection signal from first start port detection SW 14a, main CPU 110a directly proceeds to step S240 for processing. When there is an input of a detection signal from first start port detection SW 14a, main CPU 110a executes an update process of the prize ball counter, acquisition of various random number values, preliminary determination processing, and setting of various commands, etc., and proceeds to step S240 for processing. Details of the first start port detection SW input processing will be described later.

[0405] Next, in step S240, the main CPU 110a executes the second start port detection SW input process. Specifically, the main CPU 110a determines whether there is an input of a detection signal from the second start port detection SW 15a. If there is no input of a detection signal from the second start port detection SW 15a, the main CPU 110a proceeds directly to step S250. If there is an input of a detection signal from the second start port detection SW 15a, the main CPU 110a executes processes such as updating the prize ball counter, obtaining various random number values, performing pre-determination processing, and setting various commands, and then proceeds to step S250.

[0406] Note that the details of the second start port detection SW input process are the same as those of the first start port detection SW input process, which will be described in detail later. Specifically, in the second start port detection SW input process, items provided for the first start port, such as replacing "the first special symbol reservation number (U1)" in the first start port detection SW input process with "the second special symbol reservation number (U2)" and replacing "the first start port detection SW 14a" with "the second start port detection SW 15a", are replaced with items provided for the second start port.

[0407] Next, in step S250, the main CPU 110a executes the specific area detection SW input process. Specifically, the main CPU 110a determines whether there is a detection signal from the specific area detection SW 18a. If there is no input of a detection signal from the specific area detection SW 18a, the main CPU 110a proceeds directly to step S260. If there is an input of a detection signal from the specific area detection SW 18a, the main CPU 110a executes a predetermined process and then proceeds to step S260. The details of the specific area detection SW input process will be described later.

[0408] Next, in step S260, main CPU 110a executes gate detection SW input processing. Specifically, main CPU 110a determines whether there is a detection signal from gate detection SW 13a. When there is an input of a detection signal from gate detection SW 13a and the number of ordinary symbol holds (G) is 3 or less, main CPU 110a increments the number of ordinary symbol holds (G) by 1, acquires an ordinary symbol random value, and stores the acquired determination information in the smallest numbered storage unit among the first to fourth storage units of the ordinary symbol storage area where the determination information is not stored.

[0409] Even when there is an input of a detection signal from gate detection SW 13a, if the number of ordinary symbol holds (G) is 4, main CPU 110a proceeds directly to step S270. Also, when there is no input of a detection signal from gate detection SW 13a, main CPU 110a ends the input control processing as it is.

[0410] (First start port detection SW input processing of main control board) FIG. 43 is a diagram showing a flowchart of the first start port detection SW input processing of main control board 110 of gaming machine 1.

[0411] In step S230-1, main CPU 110a determines whether there is a detection signal from first start port detection SW 14a. When there is a detection signal from first start port detection SW 14a, main CPU 110a proceeds to step S230-2. When there is no detection signal from first start port detection SW 14a, main CPU 110a ends the first start port detection SW input processing.

[0412] Next, in step S230-2, main CPU 110a performs an update process of adding a predetermined number (for example, 3) to the start port prize ball counter.

[0413] Next, in step S230-3, the main CPU 110a determines whether the count value of the first special symbol reservation number (U1) counter is less than 4. If the count value of the first special symbol reservation number (U1) counter is less than 4, the main CPU 110a proceeds to step S230-4. If the count value of the first special symbol reservation number (U1) counter is not less than 4, the main CPU 110a ends the first start port detection SW input process.

[0414] Next, in step S230-4, the main CPU 110a reads out the counter value of the first special symbol reservation number (U1) stored in the storage area of the main RAM 110b, adds 1 to the read counter value of the first special symbol reservation number (U1), and stores it in the storage area of the main RAM 110b.

[0415] Next, in step S230-5, the main CPU 110a acquires a jackpot random value and stores the acquired jackpot random value in the smallest numbered storage unit among the first to fourth storage units in the first special symbol storage area provided in the main RAM 110b where the jackpot random value is not stored.

[0416] Next, in step S230-6, the main CPU 110a acquires a special symbol random value and stores the acquired special symbol random value in the smallest numbered storage unit among the first to fourth storage units in the first special symbol storage area provided in the main RAM 110b where the special symbol random value is not stored.

[0417] Next, in step S230-7, the main CPU 110a acquires a reach determination random value and stores the acquired reach determination random value in the smallest numbered storage unit among the first to fourth storage units in the first special symbol storage area provided in the main RAM 110b where the reach determination random value is not stored.

[0418] Next, in step S230-8, the main CPU 110a acquires a special symbol variation random value, and stores the acquired special symbol variation random value in the storage unit with the smallest number among the first to fourth storage units in the first special symbol storage area provided in the main RAM 110b where the special symbol variation random value is not stored.

[0419] Next, in step S230-9, the main CPU 110a executes a pre-determination process. Specifically, the main CPU 110a refers to a pre-determination table (FIG. 30) for jackpot lottery in the first special symbol stored in the main ROM 120c, and determines winning information based on the jackpot random value, special symbol random value, special symbol variation random value, and reach determination random value acquired this time.

[0420] In step S230-10, the main CPU 110a sets a start winning designation command corresponding to the winning information determined in step S230-9 in the production transmission data storage area of the main RAM 110b.

[0421] Note that the effect control board 120 can execute a preview effect indicating the possibility of a jackpot or a special loss before the start of the variation of the special symbol based on the start winning designation command received from the main CPU 110a and based on the winning in the first start port 14 this time. Examples of the preview effect include those performed over a plurality of variations such as changes in the display mode (e.g., color, design, etc.) of the first hold image 41 displayed on the image display device 31 or the display of a special background image, those in which the winning sound output at the time of a start winning is a special winning sound, and those performed at the time of winning such as causing the effect lighting device to emit special light.

[0422] In step S230-11, the main CPU 110a sets a special symbol storage number designation command indicating the first special symbol retention number (U1) determined in step S230-4 in the production transmission data storage area of the main RAM 110b, and ends the first start port detection SW input process. Note that the production control board 120 performs processes such as causing the image display device 31 to increasingly display the first retention image 41 and causing the sound output device 32 to output a winning sound based on the special symbol storage number designation command received from the main CPU 110a.

[0423] (Specific area detection SW input process of the main control board) FIG. 44 is a diagram showing a flowchart of the specific area detection SW input process of the main control board 110 of the gaming machine 1.

[0424] In step S250-1, the main CPU 110a determines whether there is a detection signal from the specific area detection SW 18a. If there is no detection signal from the specific area detection SW 18a, the main CPU 110a ends the specific area detection SW input process. If there is a detection signal from the specific area detection SW 18a, the main CPU 110a proceeds to step S250-2.

[0425] Next, in step S250-2, the main CPU 110a sets a specific area winning flag in the storage area of the specific area winning flag in the main RAM 110b. The specific area winning flag is a flag indicating that a game ball has won in the specific area 19B provided in the second large winning port 17. As described above, the second type of jackpot is a jackpot performed when a game ball enters the specific area 19B provided in the second large winning port 17.

[0426] Next, in step S250-3, the main CPU 110a sets a specific area winning designation command in the production transmission data storage area of the main RAM 110b.

[0427] Next, in step S250-4, the main CPU 110a stores the game state (the game state when a game ball wins a prize in the specific area 19B) stored in the game state flag of the main RAM 110b in the game state buffer of the main RAM 110b, and ends the specific area detection SW input process.

[0428] (Special drawing special power control process of the main control board) FIG. 45 is a diagram showing a flowchart of the special drawing special power control process of the main control board 110 of the gaming machine 1.

[0429] In step S301, the main CPU 110a loads the special drawing special power process data stored in the main RAM 110b.

[0430] In step S302, the main CPU 110a executes the process corresponding to the loaded special drawing special power process data. Specifically, when the special drawing special power process data is 0, the special symbol storage determination process in step S310 is executed; when the special drawing special power process data is 1, the special symbol variation process in step S320 is executed; when the special power process data is 2, the special symbol stop process in step S330 is executed; when the special drawing special power process data is 3, the big win game process in step S340 is executed; when the special drawing special power process data is 4, the small win game process in step S350 is executed; when the special drawing special power process data is 5, the big win game end process in step S360 is executed. Then, after executing any of the processes, the main CPU 110a ends the special drawing special power control process. The details of each control process will be described later.

[0431] (Special symbol storage determination process of the main control board) FIGS. 46 and 47 are diagrams showing a flowchart of the special symbol storage determination process of the gaming machine 1.

[0432] In step S310-1, main CPU 110a determines whether the special symbol is in the process of changing. Specifically, main CPU 110a refers to the special symbol time counter stored in main RAM 110b. If the counter value is 0, it determines that the special symbol is not in the process of changing; if the counter value is not 0, it determines that the special symbol is in the process of changing. When the special symbol is in the process of changing, main CPU 110a ends the special symbol storage determination process. When the special symbol is not in the process of changing, main CPU 110a proceeds to step S310-2 for processing.

[0433] In step S310-2, main CPU 110a determines whether the second special symbol reservation count (U2) stored in main RAM 110b is 0. When the second special symbol reservation count (U2) is 0, main CPU 110a proceeds to step S310-4 for processing. When the second special symbol reservation count (U2) is not 0, main CPU 110a proceeds to step S310-3 for processing.

[0434] In step S310-3, main CPU 110a subtracts 1 from the second special symbol reservation count (U2) in main RAM 110b and proceeds to step S310-9 for processing.

[0435] In step S310-4, main CPU 110a determines whether the first special symbol reservation count (U1) stored in main RAM 110b is 0. When the first special symbol reservation count (U1) is 0, main CPU 110a proceeds to step S310-6 for processing. When the first special symbol reservation count (U1) is not 0, main CPU 110a proceeds to step S310-5 for processing.

[0436] In step S310-5, main CPU 110a subtracts 1 from the first special symbol reservation count (U1) in main RAM 110b and proceeds to step S310-9 for processing.

[0437] In step S310-6, main CPU 110a determines whether the customer waiting state flag stored in main RAM 110b is set. The customer waiting state flag is a flag indicating that the gaming machine 1 is not performing a special game, and in a state where the number of holds is 0 and variable display is not being performed (customer waiting state). If the customer waiting flag is not set, main CPU 110a proceeds to step S310-7. If the customer waiting flag is set, main CPU 110a ends the special symbol storage determination process.

[0438] In step S310-7, main CPU 110a sets the customer waiting state flag in the customer waiting state flag storage area of main RAM 110b.

[0439] In step S310-8, main CPU 110a sets a customer waiting state designation command indicating that the gaming machine 1 is in the customer waiting state in the production transmission data storage area of main RAM 110b, and ends the special symbol storage determination process.

[0440] In step S310-9, main CPU 110a executes a shift process on the storage area of main RAM 110b. Specifically, when the second special symbol hold count is decremented by 1 in step S310-3, the data stored in the first storage unit of the second special symbol storage area of main RAM 110b is written to the zero-th storage unit of the special symbol storage area, and the data stored in the second to fourth storage units is written to the previous storage unit respectively. Also, when the first special symbol hold count is decremented by 1 in step S310-5, the data stored in the first storage unit of the first special symbol storage area of main RAM 110b is written to the zero-th storage unit of the special symbol storage area, and the data stored in the second to fourth storage units is written to the previous storage unit respectively.

[0441] Note that the data already stored in the zero-th storage unit of the special symbol storage area before the shift process of the current storage area is overwritten by new data due to the shift process of the current storage area, and thus will be erased.

[0442] In addition, although the variable display of the second special symbol is executed with priority over the variable display of the first special symbol (special 2 priority digestion), it is also possible to execute the variable display of the first special symbol and the variable display of the second special symbol in parallel (special 1 and special 2 simultaneous variation), or it is also possible to execute the variable display of the first special symbol with priority over the variable display of the second special symbol (special 1 priority digestion).

[0443] In step S310-10, the main CPU 110a sets the special symbol hold count designation command in the production transmission data storage area of the main RAM 110b. Specifically, when the main CPU 110a subtracts 1 from the second special symbol hold count (U2) in step S310-3, the main CPU 110a sets the special symbol hold count designation command indicating the subtracted second special symbol hold count in the production transmission data storage area of the main RAM 110b. Also, when the main CPU 110a subtracts 1 from the first special symbol hold count (U1) in step S310-5, the main CPU 110a sets the special symbol hold count designation command indicating the subtracted first special symbol hold count in the production transmission data storage area of the main RAM 110b.

[0444] Note that the effect control board 120 performs processing for causing the image display device 31 to display a new variable image 40, to decrease the display of the first hold image 41 and the second hold image 42, and to update and display the images of the first hold numeric image 43 and the second hold numeric image 44, with reference to the special symbol storage count designation command based on the shift processing of the current storage area received from the main CPU 110a.

[0445] In step S310-11, the main CPU 110a determines whether or not the low base short count (B) stored in the main RAM 110b is 1 or more. When the low base short count (B) stored in the main RAM 110b is 1 or more, the main CPU 110a proceeds to step S310-12. When the low base short count (B) stored in the main RAM 110b is less than 1, the main CPU 110a proceeds to step S310-14.

[0446] In step S310-12, the main CPU 110a subtracts 1 from the low base short count (B) stored in the main RAM 110b and stores the result.

[0447] In step S310-13, the main CPU 110a determines whether the low base short count (B) after subtracting 1 is 0. If the low base short count (B) after subtracting 1 is 0, the main CPU 110a proceeds to step S310-20. If the low base short count (B) after subtracting 1 is not 0, the main CPU 110a proceeds to step S311.

[0448] In step S310-14, the main CPU 110a determines whether the high base short count (J) stored in the main RAM 110b is 1 or more. If the high base short count (J) stored in the main RAM 110b is 1 or more, the main CPU 110a proceeds to step S310-15. If the high base short count (J) stored in the main RAM 110b is not 1 or more, the main CPU 110a proceeds to step S311.

[0449] In step S310-15, the main CPU 110a subtracts 1 from the high base short count (J) stored in the main RAM 110b and stores the result.

[0450] In step S310-16, the main CPU 110a determines whether the high base short count (J) after subtracting 1 is 0. If the high base short count (J) after subtracting 1 is 0, the main CPU 110a proceeds to step S310-20. If the high base short count (J) after subtracting 1 is not 0, the main CPU 110a proceeds to step S311.

[0451] In step S310-20, the main CPU 110a sets the normal game state in the game state flag storage area of the main RAM 110b and proceeds to step S311.

[0452] In addition, in this embodiment, one of the conditions for transitioning from the high-base short state to the normal state is that the number of short times at high base (J) becomes 0 (at the end of the 100th losing variation in the high-base short state, "YES" in step S310-16 of FIG. 46, S310-20). However, as described above, after a special game (e.g., the second type 9R win J) that transitions to the normal state after the end of a special game, or during a small win that triggers a transition to a special game (e.g., the second type 9R win H) that transitions to the high-base short state after the end of a special game, if the game ball does not win in the specific area 19B, etc., this also becomes a condition.

[0453] In this embodiment, the conditions for transitioning from the high-base short state to the normal state are as described above. However, conditions based on the number of variations of the normal symbol, conditions based on the number of openings of the second start port 15 triggered by winning the normal symbol, or conditions based on the number of winning times of the normal symbol may also be used.

[0454] That is, the conditions for transitioning from the high-base short state to the normal state may be, for example, that the variation display of the normal symbol has ended for the first or a predetermined number of times in the high-base short state, or that the second start port 15 has been opened once or a predetermined number of times due to winning the normal symbol, or that the winning determination of the normal symbol has been made once or a predetermined number of times, etc.

[0455] In step S311, the main CPU 110a executes a big win determination process. Specifically, the main CPU 110a refers to various tables stored in the main ROM 110c shown in FIGS. 18, 19, and 20 based on the big win random number value newly stored in the 0th storage unit, the special symbol random number value, and the type of the special symbol display device of the data shifted to the 0th storage unit, and determines the type of the special symbol, the stop symbol data, etc. Details of the big win determination process will be described later.

[0456] In step S312, the main CPU 110a determines the variation pattern of the special symbol to be executed. Specifically, based on the type of the special symbol determined in step S311, the reach determination random number value and the special symbol variation random number value newly stored in the 0th storage unit, and the first special symbol reservation number and the second special symbol reservation number, the main CPU 110a refers to the variation pattern determination table for the first special symbol (Fig. 26 (in the normal state), Fig. 27 (in the short state at low base), Fig. 28 (in the short state at high base)) and the variation pattern determination table for the second special symbol (Fig. 29) stored in the main ROM 110c to determine the variation pattern of the special symbol at the start of variation.

[0457] In step S313, the main CPU 110a sets a variation pattern designation command corresponding to the variation pattern of the special symbol determined in step S312 in the production transmission data storage area of the main RAM 110b.

[0458] Note that the production control board 120 performs processing for executing a variation production according to the variation pattern of the special symbol based on the variation pattern designation command received from the main CPU 110a.

[0459] In step S314, the main CPU 110a sets a game state designation command corresponding to the game state stored in the game state flag storage area of the main RAM 110b in the production transmission data storage area of the main RAM 110b.

[0460] In step S315, the main CPU 110a sets a short-time count designation command corresponding to the short-time count (B) at low base and the short-time count (J) at high base stored in the game state flag storage area of the main RAM 110b in the production transmission data storage area of the main RAM 110b.

[0461] In step S316, the main CPU 110a executes a process for starting the variable display of the special symbol. Specifically, the main CPU 110a sets variable display data for causing the first special symbol display device 20 or the second special symbol display device 21 to perform variable display of the special symbol in a predetermined area of the main RAM 110b.

[0462] Next, in step S317, the main CPU 110a sets the variable time of the special symbol. Specifically, the main CPU 110a sets the variable time corresponding to the variable pattern of the special symbol determined in step S312 in the special symbol time counter of the main RAM 110b. Note that the special symbol time counter is decremented every 2 ms in the counter update process within the timer interrupt process of step S110 (FIG. 41) described above.

[0463] Next, in step S318, the main CPU 110a sets 1 in the special figure special electric processing data storage area of the main RAM 110b and ends the special symbol storage determination process.

[0464] Note that in the data generation process within the timer interrupt process of step S600 (FIG. 41) described above, the main CPU 110a creates the lighting and extinguishing data of the LEDs of the first special symbol display device 20 or the second special symbol display device 21 based on the display data set in step S316. Then, in the output control process within the timer interrupt process of step S700 (FIG. 41) described above, the main CPU 110a outputs the lighting and extinguishing data of the LEDs created in step S600 to the first special symbol display device 20 and the second special symbol display device 21, thereby starting the variable display of the special symbol on the first special symbol display device 20 and the second special symbol display device 21.

[0465] (Jackpot determination process of the main control board) FIG. 48 is a diagram showing a flowchart of the jackpot determination process of the gaming machine 1.

[0466] In step S311-1, the main CPU 110a determines whether the special symbol that starts the variable display is a jackpot. Specifically, when the data newly stored in the 0th storage unit of the special symbol storage area is shifted from the 1st special symbol storage area based on the jackpot random value newly stored in the 0th storage unit of the special symbol storage area, the main CPU 110a refers to the jackpot lottery determination table for the 1st special symbol display device (FIG. 18(a)) stored in the main ROM 110c. When the data newly stored in the 0th storage unit is shifted from the 2nd special symbol storage area, the main CPU 110a refers to the jackpot lottery determination table for the 2nd special symbol display device (FIG. 18(b)) stored in the main ROM 110c to determine whether the special symbol that starts the variable display is a jackpot.

[0467] If the special symbol that starts the variable display is a jackpot, the main CPU 110a proceeds to step S311-2. If the special symbol that starts the variable display is not a jackpot, the main CPU 110a proceeds to step S311-5.

[0468] In step S311-2, the main CPU 110a executes the jackpot symbol determination process. Specifically, based on the special symbol random value newly stored in the 0th storage unit and the type of the special symbol display device that starts the variable display, the main CPU 110a refers to the jackpot symbol determination table (FIG. 19(a)) stored in the main ROM 110c to determine the type of the special symbol that starts the variable display and the stop symbol data, and stores the determined stop symbol data in the stop symbol data area of the main RAM 110b.

[0469] In step S311-3, the main CPU 110a sets the symbol designation command corresponding to the stop symbol data determined in step S311-2 in the production transmission data storage area of the main RAM 110b.

[0470] Next, in step S311-4, the main CPU 110a stores the game state information (game state information at the time of executing the jackpot determination process) stored in the game state flag of the main RAM 110b in the game state buffer of the main RAM 110b, and ends the jackpot determination process.

[0471] In step S311-5, the main CPU 110a determines whether the special symbol that starts the variable display is a minor win. Specifically, when the data newly stored in the 0th storage unit of the special symbol storage area is shifted from the 2nd special symbol storage area, the main CPU 110a refers to the jackpot lottery determination table (FIG. 18(b)) for the 2nd special symbol display device stored in the main ROM 110c based on the jackpot random number value newly stored in the 0th storage unit, and determines whether the special symbol that starts the variable display is a minor win.

[0472] The reason for performing the minor win determination only when the data newly stored in the 0th storage unit of the special symbol storage area is shifted from the 2nd special symbol storage area is that the minor win is set to be determined only for the 2nd special symbol (FIG. 18(b)). Therefore, when the data newly stored in the 0th storage unit is shifted from the 1st special symbol storage area, the main CPU 110a determines that the special symbol that starts the variable display is not a minor win.

[0473] Although the winning determination of the minor win is set to be performed only for the 2nd special symbol, the winning determination of the minor win may be performed for both the 1st special symbol and the 2nd special symbol, or may be set to be performed only for the 1st special symbol.

[0474] Then, when the special symbol that starts the variable display is a minor win, the main CPU 110a proceeds to step S311-6. When the special symbol that starts the variable display is not a minor win, the main CPU 110a proceeds to step S311-8.

[0475] Next, in step S311-6, the main CPU 110a executes the small hit symbol determination process. Specifically, based on the special symbol random number value newly stored in the 0th storage unit, the main CPU 110a refers to the small hit symbol determination table (FIG. 19(b)) stored in the main ROM 110c, determines the type of the special symbol to start the variable display and the stop symbol data, and stores the determined stop symbol data in the stop symbol data area of the main RAM 110b.

[0476] Next, in step S311-7, the main CPU 110a sets the symbol designation command corresponding to the stop symbol data determined in step S311-6 in the production transmission data storage area of the main RAM 110b, and ends the big hit determination process.

[0477] In step S311-8, the main CPU 110a determines whether the special symbol to start the variable display is a special loss. Specifically, when the data newly stored in the 0th storage unit of the special symbol storage area is shifted from the 1st special symbol storage area, the main CPU 110a refers to the big hit lottery determination table (FIG. 18(a)) for the 1st special symbol display device stored in the main ROM 110c based on the big hit random number value newly stored in the 0th storage unit, and determines whether the special symbol to start the variable display is a special loss.

[0478] The reason for performing the special loss determination only when the data newly stored in the 0th storage unit of the special symbol storage area is shifted from the 1st special symbol storage area is that the special loss is set to be determined only for the 1st special symbol (see FIG. 18). Therefore, when the data newly stored in the 0th storage unit is shifted from the 2nd special symbol storage area, the main CPU 110a determines that the special symbol to start the variable display is not a special loss.

[0479] Then, when the special symbol that starts the variable display is a special loss, the main CPU 110a proceeds to the process of step S311-9. When the special symbol that starts the variable display is not a special loss, the main CPU 110a proceeds to the process of step S311-11.

[0480] In step S311-9, the main CPU 110a executes special loss symbol determination processing. Specifically, based on the special symbol random number value newly stored in the 0th storage unit, the main CPU 110a refers to the special loss symbol determination table (FIG. 20(a)) stored in the main ROM 110c, determines the type of the special symbol that starts the variable display and the stop symbol data, and stores the determined stop symbol data in the stop symbol data area of the main RAM 110b.

[0481] Next, in step S311-10, the main CPU 110a sets the symbol designation command corresponding to the stop symbol data determined in step S311-9 in the production transmission data storage area of the main RAM 110b, and ends the jackpot determination processing.

[0482] In step S311-11, the main CPU 110a performs normal loss symbol determination processing. Specifically, based on the type of the special symbol display device that starts the variable display and the special symbol random number value newly stored in the 0th storage unit, the main CPU 110a refers to the normal loss symbol determination table (FIG. 20(b)) stored in the main ROM 110c, determines the type of the special symbol that starts the variable display and the stop symbol data, and stores the determined stop symbol data in the stop symbol data area of the main RAM 110b.

[0483] In step S311-12, the main CPU 110a sets the symbol designation command corresponding to the stop symbol data determined in step S311-11 in the production transmission data storage area of the main RAM 110b, and ends the jackpot determination processing.

[0484] (Special Symbol Variable Processing of the Main Control Board) Fig. 49 is a diagram showing a flowchart of the special symbol variation process of the main control board 110 of the gaming machine 1.

[0485] In step S320-1, the main CPU 110a determines whether the variation time of the special symbol has elapsed. Specifically, the main CPU 110a refers to the special symbol time counter stored in the main RAM 110b. If the counter value is 0, it is determined that the variation time of the special symbol has elapsed; if the counter value is not 0, it is determined that the variation time of the special symbol has not elapsed. When the variation time of the special symbol has elapsed, the main CPU 110a proceeds to step S320-2. When the variation time of the special symbol has not elapsed, the main CPU 110a ends the special symbol variation process.

[0486] In step S320-2, the main CPU 110a executes a process for performing the stop display of the special symbol. Specifically, the main CPU 110a clears the display data set in step S316 of the special symbol storage determination process, and sets in a predetermined area of the main RAM 110b the display data for causing the special symbol corresponding to the stop symbol data set in the stop symbol data area of the main RAM 110b to be stopped and displayed on the first special symbol display device 20 or the second special symbol display device 21.

[0487] Next, in step S320-3, the main CPU 110a sets a symbol determination command indicating that the special symbol has stopped in the production transmission storage area of the main RAM 110b.

[0488] Next, in step S320-4, the main CPU 110a sets the symbol stop time. Specifically, the main CPU 110a sets the symbol stop time (for example, 0.5 seconds) in the special symbol time counter storage area of the main RAM 110b.

[0489] Next, in step S320-5, the main CPU 110a sets 2 in the special figure special power processing data storage area of the main RAM 110b and ends the special symbol variation process.

[0490] (Special Symbol Stop Process of Main Control Board) FIG. 50 is a diagram showing a flowchart of the special symbol stop process of the main control board 110 of the gaming machine 1.

[0491] In step S330-1, the main CPU 110a determines whether the stop time of the special symbol has ended. Specifically, when the special symbol time counter in the main RAM 110b is 0, the main CPU 110a determines that the stop time of the special symbol has ended and proceeds to step S330-2. When the special symbol time counter in the main RAM 110b is not 0, the main CPU 110a determines that the stop time of the special symbol has not ended and ends the special symbol stop process.

[0492] In step S330-2, the main CPU 110a adds 1 to the variation count (L) counter in the main RAM 110b.

[0493] Next, in step S330-3, the main CPU 110a determines whether the stop symbol data stored in the stop symbol data storage area in the main RAM 110b is a jackpot. When the stop symbol data is a jackpot, the main CPU 110a proceeds to step S330-4. When the stop symbol data is not a jackpot, the main CPU 110a proceeds to step S330-11.

[0494] In step S330-4, the main CPU 110a sets the game state flag in the normal state in the game state flag storage area of the main RAM 110b. Next, in step S330-5, the main CPU 110a resets the low base short count (B) counter and the high base short count (J) counter in the main RAM 110b. Next, in step S330-6, the main CPU 110a resets the variation count (L) counter in the main RAM 110b.

[0495] Next, in step S330-7, the main CPU 110a executes the first type jackpot game preparation process. Specifically, the main CPU 110a determines the reference destination of the special game control table for the first type jackpot (FIG. 23(a)) stored in the main ROM 110c based on the symbol stop data stored in the stop symbol data storage area of the main RAM 110b.

[0496] Next, in step S330-8, the main CPU 110a sets the opening designation command. Specifically, the main CPU 110a determines the opening designation command from the reference destination of the special game control table for the first type jackpot determined in step 330-7, and sets the determined opening designation command in the production transmission data storage area of the main RAM 110b.

[0497] Note that when the production control board 120 receives the opening designation command from the main CPU 110a, it performs processing for executing the opening production of the jackpot game on the image display device 31, the audio output device 32, etc.

[0498] Next, in step S330-9, the main CPU 110a sets the start interval time. Specifically, the main CPU 110a determines the opening time from the reference destination of the special game control table for the first type jackpot determined in step 330-7, and sets the determined opening time in the special game timer counter of the main RAM 110b.

[0499] Next, in step S330-10, the main CPU 110a sets 3 in the special figure special electric processing data storage area of the main RAM 110b, and proceeds to step S330-24.

[0500] In step S33-11, main CPU 110a determines whether the stop symbol data stored in the stop symbol data storage area of main RAM 110b is a near miss. If the stop symbol data is a near miss, main CPU 110a proceeds to step S330-12. If the stop symbol data is not a near miss, main CPU 110a proceeds to step S330-16.

[0501] In step S330-12, main CPU 110a executes near miss game preparation processing. Specifically, based on the stop symbol data stored in the stop symbol data storage area of main RAM 110b, main CPU 110a determines the reference destination of the special game control table for near misses (Fig. 23(c)) stored in main ROM 110c. Also, main CPU 110a resets the value of the special power operation number (K) counter.

[0502] In step S330-13, main CPU 110a sets an opening designation command.

[0504] Next, in step S330-15, main CPU 110a sets 4 in the special figure special power processing data storage area of main RAM 110b, and proceeds to step S330-24.

[0505] In step S330-16, main CPU 110a determines whether the counter value of the number of fluctuations (L) in main RAM 110b has reached the specified number of times (800 times). If the counter value of the number of fluctuations (L) has reached the specified number of times (800 times), main CPU 110a transfers the process to step S330-17. If the counter value of the number of fluctuations (L) has not reached the specified number of times (800 times), main CPU 110a transfers the process to step S330-19.

[0506] In step S330-17, main CPU 110a resets the low-base short count (B) counter and the number of fluctuations (L) counter of main RAM 110b, and proceeds with the process to step S330-18.

[0508] In step S330-19, main CPU 110a determines whether the stop symbol data stored in the stop symbol data storage area of main RAM 110b is a special loss. If the stop symbol data is a special loss, main CPU 110a proceeds with the process to step S330-20. If the stop symbol data is not a special loss, main CPU 110a proceeds with the process to step S330-22.

[0509] In step S330-20, the main CPU 110a executes game state setting processing. Specifically, the main CPU 110a refers to the special losing symbol stop setting table (Figure 22) stored in the main ROM 110c based on the stop symbol data stored in the stop symbol data storage area of the main RAM 110b and the game state flag stored in the game state flag storage area, determines the game state at the time of special losing stop, and sets the determined game state in the game state flag storage area of the main RAM 110b.

[0510] Next, in step S330-21, the main CPU 110a executes remaining count setting processing. Specifically, the main CPU 110a refers to the special losing symbol stop setting table (Figure 22) stored in the main ROM 110c based on the stop symbol data stored in the stop symbol data storage area of the main RAM 110b and the game state flag stored in the game state flag storage area, determines the low base short count (B) and the high base short count (J) at the time of special losing stop, and sets the determined low base short count (B) and high base short count (J) at the time of special losing stop in the low base short count (B) counter and the high base short count (J) counter of the main RAM 110b.

[0511] Next, in step S330-22, the main CPU 110a generates the count specification command indicated by the low base short count (B) counter of the main RAM 110b and generates the count specification command indicated by the high base short count (J) counter of the main RAM 110b, and sets the generated count specification commands in the production transmission data storage area.

[0512] In step S330-23, the main CPU 110a sets 0 in the special symbol special power processing data storage area of the main RAM 110b, and proceeds to step S330-24.

[0513] In step S330-24, the main CPU 110a sets a game state designation command corresponding to the game state stored in the game state flag storage area of the main RAM 110b in the production transmission data storage area, and ends the special symbol stop process.

[0514] (Jackpot game process of main control board) FIG. 51 is a diagram showing a flowchart of the jackpot game process of the main control board 110 of the gaming machine 1.

[0515] In step S340-1, the main CPU 110a determines whether the current process is during the jackpot opening. If the main CPU 110a is during the opening, the process proceeds to step S340-2. If the main CPU 110a is not during the opening, the process proceeds to step S340-6.

[0516] In step S340-2, the main CPU 110a determines whether the start interval time has elapsed. Specifically, if the special game timer counter stored in the main RAM 110b is 0, the main CPU 110a determines that the start interval time has elapsed, and the process proceeds to step S340-3. If the special symbol time counter stored in the main RAM 110b is not 0, the main CPU 110a determines that the start interval time has not elapsed, and ends the current jackpot game process.

[0517] In step S340-3, the main CPU 110a sets the count value of the round number (R) counter stored in the main RAM 110b to 1.

[0518] In step S340-4, main CPU 110a executes the big winning opening process. Specifically, main CPU 110a reads the table number of the big winning opening / closing control table from the reference destination of the first type jackpot special game control table (Fig. 23(a)) determined in step S330-7 and the reference destination of the second type jackpot special game control table (Fig. 23(b)) determined in step S351-5 described later. Based on the read table number and the current round number (R), main CPU 110a refers to the first type jackpot big winning opening / closing control table (Fig. 24(a)) or the second type jackpot big winning opening / closing control table (Fig. 24(b)) stored in main ROM 110c, determines the opening time of the first big winning opening 16, and sets the determined opening time in the special game timer counter. Also, main CPU 110a sets the energization data for energizing the first big winning opening solenoid 16c to open the first big winning opening / closing door 16b. Further, main CPU 110a sets 1 in the special power operation number (K) of main RAM 110b.

[0519] In step S340-5, main CPU 110a executes the round start command transmission determination process. Specifically, main CPU 110a sets the round start command corresponding to the current round number (R) in the production transmission data storage area and ends the jackpot game process.

[0520] In step S340-6, main CPU 110a determines whether the current process is during the ending of a jackpot. If main CPU 110a is during the ending, the process proceeds to step S340-17. If main CPU 110a is not during the ending, the process proceeds to step S340-7.

[0521] In step S340-7, main CPU 110a determines whether the first major winning opening 16 is closed. Specifically, when no energization data is set in the first major winning opening opening / closing solenoid 16c, main CPU 110a determines that the first major winning opening 16 is closed. If the first major winning opening 16 is closed, main CPU 110a proceeds to step S340-8. If the first major winning opening 16 is not closed, main CPU 110a proceeds to step S340-9.

[0522] In step S340-8, main CPU 110a determines whether the closing time of the first major winning opening 16 has elapsed. Specifically, when the value of the special game timer counter is 0, main CPU 110a determines that the closing time of the first major winning opening 16 has elapsed. If main CPU 110a determines that the closing time of the first major winning opening 16 has elapsed, it proceeds to step S340-4. If main CPU 110a determines that the closing time of the first major winning opening 16 has not elapsed, it ends the jackpot game process.

[0523] In step S340-9, main CPU 110a determines whether the release end condition of the first major winning opening 16 is satisfied. Specifically, when the count value of the major winning opening ball entry number (C) counter in main RAM 110b reaches a specified number (for example, 9), or when the special game timer counter is 0 (when the release time has elapsed), main CPU 110a determines that the release end condition of the first major winning opening 16 is satisfied. If the release end condition of the first major winning opening 16 is satisfied, main CPU 110a proceeds to step S340-10. If the release end condition of the first major winning opening 16 is not satisfied, it ends the jackpot game process.

[0524] In step S340-10, main CPU 110a executes the closing process of the first large winning opening 16. Specifically, main CPU 110a stops the energization data that was energizing the first large winning opening solenoid 16c in order to close the first large winning opening closing door 16b. Also, main CPU 110a refers to the first major jackpot winning opening opening / closing control table (Fig. 24(a)), determines the closing time of the first large winning opening 16 based on the count value of the current round number (R) counter, and sets the determined closing time in the special game timer counter.

[0525] In step S340-11, main CPU 110a executes the round data initialization process. Specifically, main CPU 110a resets the count value of the winning opening ball entry number (C) counter in main RAM 110b. Note that main CPU 110a does not reset the count value of the round number (R) counter in main RAM 110b.

[0526] Next, in step S340-12, main CPU 110a determines whether the count value of the round number (R) in main RAM 110b is the maximum value. If the count value of the round number (R) in main RAM 110b is the maximum value, main CPU 110a proceeds to step S340-14. If the count value of the round number (R) in main RAM 110b is not the maximum value, main CPU 110a proceeds to step S340-13.

[0527] In step S340-13, main CPU 110a adds 1 to the count value of the round number (R) in main RAM 110b and ends the jackpot game process.

[0528] In step S340-14, main CPU 110a resets the count value of the round number (R) in main RAM 110b.

[0529] In step S340-15, the main CPU 110a sets an ending designation command. Specifically, the main CPU 110a reads the ending designation command from the reference destination of the first special big win game control table (Fig. 23(a)) determined in step S330-7 and the reference destination of the second special big win game control table (Fig. 23(b)) determined in step S351-5 described later, and sets the read ending designation command in the production transmission data storage area.

[0530] In step S340-16, the main CPU 110a reads the ending time from the reference destination of the first special big win game control table (Fig. 23(a)) determined in step S330-7 and the reference destination of the second special big win game control table (Fig. 23(b)) determined in step S351-5 described later, and sets the read ending time in the special game timer counter.

[0531] In step S340-17, the main CPU 110a determines whether the end interval time has elapsed. Specifically, when the value of the special game timer counter is 0, the main CPU 110a determines that the end interval time has elapsed. When the main CPU 110a determines that the end interval time has elapsed, it proceeds to step S340-18. When the main CPU 110a determines that the end interval time has not elapsed, it ends the big win game process.

[0532] In step S340-18, the main CPU 110a sets 5 in the special drawing special power processing data of the main RAM 110b and ends the big win game process.

[0533] (Small win game process of the main control board) Fig. 52 is a diagram showing a flowchart of the small win game process of the main control board 110 of the gaming machine 1.

[0534] In step S350-1, main CPU 110a determines whether the current process is during a small win opening. If main CPU 110a determines that it is during an opening, it proceeds to step S350-2. If main CPU 110a determines that it is not during an opening, it proceeds to step S350-5.

[0535] In step S350-2, main CPU 110a determines whether the start interval time has elapsed. Specifically, if the special game timer counter in main RAM 110b is 0, main CPU 110a determines that the start interval time has elapsed and proceeds to step S350-3. If the special game timer counter in main RAM 110b is not 0, main CPU 110a determines that the start interval time has not elapsed and ends the small win game process.

[0536] In step S350-3, main CPU 110a executes the big winning opening process. Specifically, main CPU 110a increments the value of the special electric operation number (K) counter in main RAM 110b by 1. Main CPU 110a refers to the small win big winning opening / closing control table (Figure 25(a)) stored in main ROM 110c, determines the opening time based on the current value of the special electric operation number (K) counter, and sets the determined opening time in the special game timer counter of main RAM 110b. Then, in order to open the second big winning opening / closing door 17b, main CPU 110a sets the energization data to energize the second big winning opening solenoid 17c.

[0537] Next, in step S350-4, the main CPU 110a executes specific winning opening / closing control processing. Specifically, the main CPU 110a refers to the specific area opening / closing control table for small wins (FIG. 25(b)) stored in the main ROM 110c, determines the opening time since the second largest winning opening 17 is opened, the opening time of the slide member 19C, and the closing time of the slide member 19C, sets each determined time in a predetermined counter in a predetermined area of the main RAM 110b, and ends the small win game process. Note that the movement control of the slide member 19C is executed based on the values of these set predetermined counters.

[0538] In step S350-5, the main CPU 110a determines whether the current process is during the ending of a small win. If the main CPU 110a is during the ending, the process proceeds to step S350-13. If the main CPU 110a is not during the ending, the process proceeds to step S350-6.

[0539] In step 350-6, the main CPU 110a determines whether the second largest winning opening 17 is open. Specifically, if energization data is set in the second largest winning opening opening / closing solenoid 17c, the main CPU 110a determines that the second largest winning opening 17 is open. If the main CPU 110a determines that the second largest winning opening 17 is open, the process proceeds to step S350-8. If the main CPU 110a determines that the second largest winning opening 17 is not open, the process proceeds to step S350-7.

[0540] In step S350-7, the main CPU 110a determines whether the closing time of the second largest winning opening 17 has elapsed. Specifically, if the value of the special game timer counter is 0, the main CPU 110a determines that the closing time of the second largest winning opening 17 has elapsed. If the main CPU 110a determines that the closing time of the second largest winning opening 17 has elapsed, the process proceeds to step S350-3. If the main CPU 110a determines that the closing time of the second largest winning opening 17 has not elapsed, the small win game process ends.

[0541] In step S350-8, the main CPU 110a determines whether the release end condition of the second largest winning opening 17 is satisfied. Specifically, when the count value of the winning opening ball entry number (C) counter in the main RAM 110b reaches a specified number (for example, 9), when the special game timer counter is 0 (when the release time has elapsed), or when the specific area winning flag is set, the main CPU 110a determines that the release end condition of the second largest winning opening 17 is satisfied. When the release end condition of the second largest winning opening 17 is satisfied, the main CPU 110a proceeds to step S350-9. When the release end condition of the second largest winning opening 17 is not satisfied, the main CPU 110a ends the small win game process.

[0542] In step S350-9, the main CPU 110a executes the closing process of the second largest winning opening 17. Specifically, in order to close the second largest winning opening and closing door 17b, the main CPU 110a stops the energization data that was energizing the second largest winning opening solenoid 17c. Also, the main CPU 110a refers to the closing time in the small win winning opening opening / closing control table stored in the main ROM 110c, determines the closing time of the second largest winning opening 17 based on the current count value of the special power operation number (K) counter, and sets the determined closing time to the special game timer counter.

[0543] In step S350-10, the main CPU 110a determines whether the small win game has ended. Specifically, when the value of the special power operation number (K) counter in the main RAM 110b is 10, the maximum value, when the value of the winning opening ball entry number (C) counter has reached the specified number (for example, 9), or when the specific area winning flag is set, the main CPU 110a determines that the small win game has ended. When the main CPU 110a determines that the small win game has ended, it proceeds to step S350-11. When the main CPU 110a determines that the small win game has not ended, it ends the small win game process.

[0544] In step S350-11, the main CPU 110a executes the small hit game end process. Specifically, the main CPU 110a resets the value of the special electric operation number (K) counter and the value of the big winning opening ball entry number (C) counter in the main RAM 110b.

[0545] Next, in step S350-12, the main CPU 110a executes the ending process. Specifically, the main CPU 110a sets the small hit ending designation command in the production transmission data storage area.

[0546] In step S350-13, the main CPU 110a determines whether the end interval time has elapsed. Specifically, when the value of the special game timer counter in the main RAM 110b is 0, the main CPU 110a determines that the end interval time has elapsed. If the main CPU 110a determines that the end interval time has elapsed, it proceeds to step S350-14. If the main CPU 110a determines that the end interval time has not elapsed, it ends the small hit game process.

[0547] In step S350-14, the main CPU 110a determines whether the specific area winning flag is set in the specific area winning flag storage area of the main RAM 110b. If the main CPU 110a determines that the specific area winning flag is not set, it proceeds to step S350-15. If the main CPU 110a determines that the specific area winning flag is set, it proceeds to step S351.

[0548] In step S350-15, the main CPU 110a sets the normal state flag in the game state flag storage area of the main RAM 110b.

[0549] In step S350-16, the main CPU 110a sets 0 in the special figure special electric process data of the main RAM 110b and ends the small hit game process.

[0550] In step S351, the main CPU 110a executes the second type of jackpot game transition process and then ends the small win game process. The second type of jackpot game transition process will be described later.

[0551] As shown in the description of the above flowchart, if no game ball enters the specific area 19B during the small win game, the game state after the end of the small win game will be the normal state. Therefore, even if a small win that triggers the second type of jackpot and leads to the high base short state occurs, if no game ball enters the specific area 19B during the small win game, not only can the second type of jackpot not be obtained, but the game will transition to a normal state that is more disadvantageous than the high base short state after the end of the small win game.

[0552] However, it can be said that it is too harsh on the player to transition from the high base short state to the normal state just because no game ball enters the specific area 19B even once during the small win game in all small wins.

[0553] Therefore, even if no game ball enters the specific area 19B during the small win game in the high base short state, it may be possible to make the transition to the normal state only in the case of a specific small win.

[0554] Specifically, it may be possible to make the transition to the normal state only when no game ball enters the specific area 19B in the small win that triggers the second type of jackpot (second type 9R win J) which transitions to the normal state after the end. Also, even for a small win that triggers the second type of jackpot and transitions to the high base short state after the end, it may be possible to make the transition to the normal state only for a specific small win (for example, the small win that triggers the second type 2R win I), when no game ball enters the specific area 19B.

[0555] Also, according to the number of small wins in which the game ball did not enter the specific area 19B during the game, it may be possible to shift from the high base short state to the normal state. For example, the number of small win games in which the game ball did not enter the specific area 19B may be counted, and after the end of the small win game when the count value reaches the third time, it may be shifted from the high base short state to the normal state.

[0556] Furthermore, according to both the number of small wins in which the game ball did not enter the specific area 19B during the game and the type of small win, it may be possible to shift from the high base short state to the normal state after the end of the small win game.

[0557] Also, during the low base short state, since the release time of the movable piece 15b is 0.11 seconds, it is very difficult for the game ball to enter the second start port 15 compared to the high base short state. However, depending on the firing intensity and firing timing of the game ball, very rarely, even during the low base short state, the game ball may enter the second start port 15, and it may also happen that the player wins a small win in the winning or losing lottery according to the entry.

[0558] In that situation, if the player deliberately stops firing the game ball during the small win game and the game ball does not enter the specific area 19B during the small win game, it becomes possible to intentionally shift to the normal state, which is more advantageous than the low base short state, in order to shift from the low base short state to the normal state.

[0559] Therefore, in the case of a small win that occurred during the low base short state, even if the game ball did not enter the specific area 19B during the small win game, it may be possible to continue the low base short state without shifting to the normal state after the end of the small win game.

[0560] (Second type big win game transition process of the main control board) FIG. 53 is a diagram showing a flowchart of the second type big win game transition process of the main control board 110 of the gaming machine 1.

[0561] In step S351-1, main CPU 110a clears the specific area winning flag storage area in main RAM 110b. Next, in step S351-2, main CPU 110a sets the normal state flag in the game state flag storage area of main RAM 110b.

[0562] Next, in step S351-3, main CPU 110a resets the counter value of the low base short count (B) counter and the counter value of the high base short count (J) counter in main RAM 110b. Next, in step S351-4, main CPU 110a resets the counter value of the variation count (L) counter in main RAM 110b.

[0563] Next, in step S351-5, main CPU 110a executes the second type jackpot game preparation process. Specifically, based on the stop symbol data stored in the stop symbol data storage area of main RAM 110b, main CPU 110a determines the reference destination of the special game control table for the second type jackpot (Fig. 23(b)) stored in main ROM 110c. Main CPU 110a reads the opening time from the determined reference destination, sets the determined opening time in the special game timer counter of main RAM 110b, and sets 0 in the count value of the round number (R) counter of main RAM 110b. Main CPU 110a reads the opening designation command from the determined reference destination and sets the read opening designation command in the production transmission data storage area.

[0564] Next, in step S351-6, main CPU 110a sets 3 in the special symbol special power processing data in main RAM 110b and ends the second type jackpot game transition process.

[0565] (Jackpot game end process of main control board) FIG. 54 is a diagram showing a flowchart of the jackpot game end process of main control board 110 of gaming machine 1.

[0566] In step S360-1, the main CPU 110a loads the stop symbol data stored in the stop symbol data storage area of the main RAM 110b and the game state information stored in the game state buffer.

[0567] Next, in step S360-2, the main CPU 110a executes the remaining number setting process. Specifically, based on the loaded stop symbol data and game state information, the main CPU 110a refers to the special game end setting table (Fig. 21) stored in the main ROM 110c, and determines the low base short number (B) and the high base short number (J) at the end of the special game.

Specifically, the main CPU 110a sets the variation time corresponding to the variation pattern of the normal symbol determined in step S410-8 in the normal symbol time counter of the main RAM 110b, and ends the normal symbol variation process.

[0588] In step S410-12, the main CPU 110a determines whether the variation time of the normal symbol has ended. Specifically, when the normal symbol time counter of the main RAM 110b is 0, the main CPU 110a determines that the variation time of the normal symbol has ended.
