[Problems to be solved by the invention]
By the way, in order to enhance the production operation in a gaming machine, it is necessary to transmit a control command to all the sub-control boards, and the bit length of the control command has to be long. Is too large, and as a result, there is a problem that the original control operation may be hindered.
[0005]
On the other hand, no matter how advanced the staging operation of the gaming machine is, if the same type of gaming machine performs exactly the same operation, it lacks individuality and becomes unsatisfactory.
[0006]
The present invention has been made in view of such a problem, and provides a gaming machine that does not place a burden on a main control board even when a sophisticated rendering operation is advanced, and that is capable of producing a unique rendering. The task is to

Are also suitable.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the gaming machine of the present invention will be described in more detail based on embodiments. FIG. 1 is a block diagram illustrating the entire configuration of the pachinko machine according to the embodiment. The illustrated pachinko machine includes a main control board 1 for mainly controlling a game operation, a symbol control board 2 for controlling an operation of the display device 8, an audio control board 3 for realizing a sound game effect, and lamps. , A lamp control board 4 for paying out game balls, a payout control board 5 for paying out game balls, a firing control board 7 controlled by the payout control board 5 for firing game balls, and receiving a 24 V AC to apply DC voltage to various parts of the device. The power supply board 6 to be supplied is mainly configured.
[0011]
The main control board 1, the symbol control board 2, the voice control board 3, the lamp control board 4, and the payout control board 5 are each composed of a computer circuit having a one-chip microcomputer. Individual control operations are realized based on control commands from the board 1. Note that all control commands are divided into MODE data indicating the type of command and EVENT data indicating the specific contents of the command. Each data is 8 bits and has a 16-bit configuration as a whole.
[0012]
FIG. 2 is a block diagram illustrating a circuit configuration of the main control board 1. As shown in the figure, the main control board 1 includes a CPU circuit 1a composed of a one-chip microcomputer, a system clock generator 1b that generates a clock signal Φ0 having a frequency that is an integral multiple of the CPU operation clock CLK, and an address signal from the CPU. A decode circuit 1c for generating a chip select signal for each section based on the data, an output port circuit 1d for outputting data from the CPU, an input port circuit 1e for the CPU to take in external data, and sub-control boards 2 to 5 And a switch input circuit 1g for inputting the ON / OFF state of switches of each part of the game board. The CPU circuit 1a has a built-in CPU core equivalent to Z80CPU (Zilog).
[0013]
3 and 4 are flowcharts showing a control program of the main control board 1. The control program of the main control board 1 is executed after the power is turned on, and usually ends with an interrupt permission process (ST14). A system reset process program (Main in FIG. 3) and a timer interrupt process (Maskable Interrupt) started at predetermined time intervals. A prohibitable interrupt) program (TimerINT in FIG. 4) and an NMI processing program (not shown) driven by an NMI (Non Maskable interrupt) signal to back up the register value of the CPU when the power supply voltage falls below a predetermined value. ing.
[0014]
Hereinafter, the system reset processing program (main routine) will be described with reference to FIG. The main routine is started not only when the power is turned on, but also when the count value of the watchdog timer reaches a predetermined value and the CPU is reset due to a program runaway. In addition, there are two patterns when the power is turned on, and it is considered that the power is restored from the power failure state and the pachinko hall is opened.
[0015]
In the main routine shown in FIG. 3, first, the Z80 CPU sets itself to the interrupt disabled state, and initializes each part of the one-chip microcomputer including the Z80 CPU core (ST1). After setting the CPU to the interrupt mode 2 (ST2), the CPU checks the RAM clear switch (ST3).
[0016]
The RAM clear switch is a switch for clearing the RAM area at the end of business or start of business. Assuming the start of business, the game state of the previous day is stored by the NMI processing program unless special processing is performed, and the contents of the RAM are held by the backup power supply. Therefore, for example, in the case where the end of business on the previous day is in the middle of the big hit game, at the start of business, the attendant turns on the RAM clear switch and turns on the power. However, usually, the RAM clear switch is not operated because it is complicated, and the power is turned on in the OFF state.
[0017]
Therefore, usually, following the determination in step ST3, the content of the backup flag BFL is determined (ST4). The backup flag BFL is data indicating whether the backup data saved in the NMI process has been restored to the original state. In this embodiment, the backup flag BFL is set to 5AH by the NMI processing program. The processing is cleared to zero in the process of step ST12 in FIG.
[0018]
At the time of normal power-on without turning on the RAM clear switch or at the time of recovery from a power failure state, the backup flag BFL = 5AH, so that a checksum process is performed next (ST5). The sum value (the value of the SUM address) checked here is calculated and stored in the NMI process, and is held by the backup power supply even after the power is turned off. Therefore, except for the case where the power supply voltage drops abnormally quickly, in the process of step ST5, the total value obtained by adding the data of the RAM area again by 8 bits matches the value of the SUM address. Become.
[0019]
If the sum calculated by the recalculation (8-bit addition) matches the value of the SUM address, the 16-bit data read from the SP storage area storing the value of the SP (stack pointer) in the NMI process is read by the CPU. (ST6). Next, the data in the RAM area backed up in the NMI process at the time of the power failure is read, and a backup restoration command is created (ST7 to ST9).
[0020]
Here, the payout control board backup return command creation processing (ST7) means a preparatory operation for rechecking the error signal and outputting a control command according to the current state of the gaming machine to the payout control board 5. . For example, in the case of an error state where the lower plate is full before the power failure, the error state is stored in the backup data.However, since it is highly possible that the player will collect the game balls due to the power failure, the error signal will be renewed. They are checking the current situation.
[0021]
The backup control command creation processing for the symbol control board or the lamp control board (ST8, ST9) is a so-called probable state in which the gaming machine before the power failure is in a big hit state or a winning probability is increased. In such a case, the processing is to set the background color of the display device 8 according to the operation state or set the lighting state of the hold lamp.
[0022]
When the processes in steps ST8 and ST9 are completed, a POP instruction is executed to restore the values of the respective registers from the stack area (ST10) and set the initial value of the process management counter CT (ST11). The process management counter CT is a binary counter that is updated in the subsequent random number update process of the timer interrupt (FIG. 4). In the present embodiment, the process management counter CT is used to add individuality to each gaming machine. The initial value is determined randomly.
[0023]
However, since the process management counter CT is a binary counter, the initial value to be given is either 0 or 1, for example, the least significant bit of the R register (refresh register) built in the Z80 CPU, or the step ST5. Randomness can be realized by using the least significant bit of the SUM address to be checked. In any case, in this embodiment, the value of the process management counter CT is initialized at random even in a situation (ST6 to ST14) in which the information before the power shutdown (the day before) is taken over. A new personality is given to the gaming machine.
[0024]
With the above processing, the return processing from the power shutdown is temporarily completed, and the backup flag BFL is cleared to zero to indicate that (ST12). Finally, it is checked whether or not the interrupt was disabled before the power was shut off based on the value of the restored AF register (ST13), and the processing is terminated in the interrupt disabled state, or the interrupt is enabled. (ST14), and the process ends. When the RET instruction is executed, the value of the PC (program counter) at the time of the interruption, which has been subjected to the PUSH processing, is restored to the stack area, and the processing returns to the processing before the power is turned off.
[0025]
On the other hand, if the RAM clear switch is ON, the backup flag BFL = 0, or the checksum processing indicates an abnormality, the RAM area built in the one-chip microcomputer is cleared to zero (ST15). . The processing in step ST15 is executed when the power is turned on with the RAM clear switch turned ON, when the value of the SUM address does not match the recalculated value due to some trouble, or when the CPU goes out of control. It is conceivable that the watchdog timer is activated and the CPU is forcibly reset.
[0026]
In any of the above cases, the operation in step ST15 erases all the game states up to that point (or the day before), so that even if the CPU goes out of control or the game hall is closed yesterday during the big hit game, Then, the game is started in a state where the game has returned to the initial state.
[0027]
Next, the value of the process management counter CT is randomly set to an initial value of 0 or 1 (ST16). The method of setting the initial value is the same as that of step ST11. However, the processing of step ST16 is provided in addition to the processing of step ST11 regardless of whether the RAM clear switch is pressed when the power is turned on. First, the initial value of the processing management counter CT is determined at random, and individuality is given to each gaming machine.
[0028]
When the above processing is completed, the CPU is set to the interrupt disabled state (DI) (ST17), and the value of the sub-counter BGN that determines the initial value of the big hit counter BG is updated (ST18). Note that the value of the sub-counter BGN is an initial value of the big hit counter BG in the next round operation every time the big hit counter BG makes a round of the numerical range, and is the same numerical value range as the big hit counter BG ( 0 to MAX-1). Since the sub-counter BGN is updated while the CPU does not accept an interrupt (DI), the sub-counter BGN is being updated and the value of the fluid sub-counter BGN is used in the timer interrupt processing. Never be.
[0029]
Next, with the CPU returned to the interrupt permission state (EI), the value of the off symbol counter is updated (ST19, ST20). The out-of-design symbol counter is used to determine what mode to take when the out-of-slung state is reached in the big hit determination in the special symbol processing (ST42) of FIG. The updating of the out-of-design symbol counter and the updating of the sub-counter BGN are executed in an infinite loop as shown in FIG. 3, so that the value of each counter can be used as a random value having sufficient randomness.
[0030]
FIG. 4 is a flow chart showing the contents of an interrupt processing program of a timer interrupt INT (interrupt that cannot be masked interrupt) generated every 4 msec during the infinite loop processing (ST17 to ST20) of the main routine shown in FIG. When a timer interrupt occurs, the contents of each register are saved in the stack area (ST30), and then a random number creation process is first performed (ST31).
[0031]
This random number generation processing includes updating processing of the hit counter RG and the big hit counter BG used in the lottery operation in the normal symbol processing ST38 and the special symbol processing ST42. The random number creation process (ST21) also includes an update process of the process management counter CT for determining the personality of the gaming machine. In this embodiment, the processing management counter CT is a binary counter updated by software, and changes cyclically as 0 → 1 → 0 → 1 → 0 → 1 →. Is randomly determined in step ST11 or ST16.
[0032]
Further, the random number generation process of step ST31 includes a process of updating the random number X for the big hit symbol for determining which big hit symbol is to be selected as the winning symbol when the big hit state is won in the special symbol process (ST42). Have been. In this embodiment, since ten symbols [1, 2, 3, 4, 5, 6, 7, 8, 9, *] are prepared as big hit symbols, the random number X for big hit symbols is 0 to 0. This is a decimal counter that is updated in the numerical range of 9, and the winning symbol is uniquely determined by the value of the big hit symbol random number X.
[0033]
Specifically, as shown in FIG. 5, when the random number X for the jackpot symbol is an even number, the calculation result Y of X / 2 + 1 becomes the jackpot symbol Y (three stop symbols). When the symbol random number X is an odd number, the calculation result Y of (X-1) / 2 + 6 becomes the big hit symbol Y. Here, when Y = 10, it means a symbol “*”. Actually, a shift operation is used, and as shown in FIG. 5B, the processing of X / 2 and (X-1) / 2 is performed by shifting the random number X for the big hit symbol right by 1 bit. Is achieved.
[0034]
When the random number generation process in step ST31 is completed, a command transmission process for transmitting a control command to each sub-control board is performed (ST32). However, if all the control commands are transmitted to all the sub-control boards at the same time, a considerable processing time is required for the transmission processing, and other necessary time may not be secured. Therefore, in this embodiment, the entire control commands are classified into a first group and a second group of control commands, and the control commands belonging to each group are transmitted alternately at each timer interrupt. Specifically, when the processing management counter CT = 0, the first group of control commands is transmitted, and when the processing management counter CT = 1, the second group of control commands is transmitted. .
[0035]
Although the method of classifying the control commands is not particularly limited, in this embodiment, the control commands are transmitted in time sequence in the order of the payout control board 5 → the symbol control board 2 → the voice control board 2 → the lamp control board 3. As much as possible, control commands of high importance to be transmitted at the same time (that is, in the same timer interrupt process) are classified into a first group of control commands, and other control commands are classified into a second group of control commands. . As a result, in the timer interrupt process for transmitting the first group of control commands, a certain amount of time is required for the process of step ST32. However, in the timer interrupt process for transmitting the second group of control commands, the process of step ST32 is not performed. It will end quickly.
[0036]
The time charts of FIGS. 6A and 6B illustrate this relationship. The processing time for transmitting the first group of control commands (displayed as command transmission 1) corresponds to the second group of control commands (commands). Transmission 2) is considerably longer than the processing time for transmitting. When the command transmission process as described above is completed, next, a timer subtraction process is performed for a timer managing the time of each game operation (ST33). Each timer subtracted here is for managing the opening time of the electric tulip and the big winning opening and other game effect time.
[0037]
Next, signals of various switches including a symbol starting port and a gate detection switch are input and stored (ST34). Among the stored switch signals, a switch signal generated when a game ball wins the symbol starting port is particularly important, and only when this switch input is recognized, the jackpot lottery process in the special symbol process (ST42). Be executed.
[0038]
By the way, in this embodiment, the switch input process (ST34) is provided after the command transmission process (ST32), so that the timing of the switch input process in the timer interrupt process is relatively slightly changed for each timer interrupt. Will do. Therefore, for example, in the case of FIG. 6A, in the switch input process described as SW detection {circle around (1)}, the switch input process executed at a relatively late timing starts with the switch input process executed at a relatively early timing. The winning state of the game ball generated up to the input processing is detected. In FIG. 6, the relatively short detection period is described as a winning detection period A.
[0039]
On the other hand, in the switch input process described as SW detection {circle around (2)} in FIG. 6 (a), the switch input process executed at a relatively early timing to the switch input process executed at a relatively late timing occurs. The winning state of the game ball is detected. In FIG. 6, the relatively long detection period is described as a winning detection period B.
[0040]
The relatively long prize detection period B and the relatively short prize detection period A are alternately repeated, but the prize detection periods A and B having different periods and the process management in which the initial value is randomly determined. In this embodiment, each gaming machine is given personality by utilizing the counter CT.
[0041]
For example, as shown in FIG. 6A, when the initial value of the processing counter CT is 0 (first individuality), the switch detection is relatively long, such as (2), (4),. In the switch input process after the winning detection period B, the big hit symbol random number X becomes an even number such as 2, 4, 6... As a result, as shown in FIG. 4, 5, 1] is selected. On the other hand, in the switch input process after a relatively short prize detection period A, such as switch detection (1), (3),..., The jackpot symbol random number X is an odd number such as 1, 3, 5,. As a result, as shown in FIG. 5, the latter half numerical value [6, 7, 8, 9, *] is selected as the stop symbol.
[0042]
The above is the operation in the case of the first individuality in which the initial value of the process management timer CT is set to 0. Conversely, the operation in the case of the second individuality in which the initial value of the process management timer CT is set to 1 Operates as shown in FIG. 6B. In this case, in the switch input processing after a relatively long winning detection period B, the big hit symbol random number X is an odd number such as 1, 3, 5,... 6, 7, 8, 9, *] are selected. On the other hand, in the switch input process after the relatively short winning detection period A, the big hit symbol random number X is an even number such as 2, 4, 6... 3, 4, 5] is selected.
[0043]
As is apparent from the above description, in the gaming machine with the first individuality, the first half value [1, 2, 3, 3] is less likely to be a big hit in the latter half value [6, 7, 8, 9, *]. [4,5], the possibility of a big hit is higher. On the other hand, in the gaming machine with the second individuality, the possibility of a big hit with the first half numerical value [1,2,3,4,5] is larger than the possibility of the big hit in the second half The possibility of a big hit with a numerical value [6, 7, 8, 9, *] is higher.
[0044]
As a result, in the gaming machine with the first individuality, the reach production with the latter half numerical value like (8 ↓ 8) cannot be expected much, but the reach production with the first half numerical value like (2 ↓ 2) is This can be expected, and it will be possible to realize a new and unique playability. Moreover, since this individuality is updated every time the power is turned on, it is also unique in that sense.
[0045]
The method of giving the gaming machine individuality by combining the bisected command transmission processing (ST32) and the subsequent switch input processing has been described above, but the operation after the switch input processing is almost the same as that of the conventional gaming machines. It is.
[0046]
In the following, an error management process is performed following the switch input process (ST34) (ST35). The error management process is to determine whether or not an abnormality has occurred inside the device, such as when supply of the game balls has stopped or the game balls have not been clogged.
[0047]
Next, after creating a control command for the payout control board (ST36), a normal symbol process is performed on condition that the current operation mode is not the hitting mode (ST38). The ordinary symbol processing means determination of whether to activate an ordinary electric accessory such as an electric tulip. Specifically, when it is determined by the switch input processing in step ST34 that the game ball has passed the gate, the hit counter RG updated in the random number generation processing (ST31) is compared with the hit winning value. . Then, if the comparison result is a winning state, the operation mode is changed to the winning operation mode. If it is in the middle of a hit, a process for operating an ordinary electric accessory such as an electric tulip is performed (ST40).
[0048]
Subsequently, special symbol processing is performed on condition that the current operation mode is not the big hit operation mode (ST42). The special symbol processing is a determination as to whether or not to activate a first-class special electric accessory such as a special winning opening. Specifically, when it is determined by the switch input process of step ST34 that the game ball has passed through the symbol starting port, the big hit counter BG updated in the random number generation process (ST31) is set to the big hit value Hit. Contrast with. Then, if the comparison result is a winning state, the operation mode is changed to the big hit operation mode, and a winning symbol is determined based on the value of the big hit symbol random number X updated in the random number generation process (ST31).
[0049]
As described above, in the gaming machine to which the first individuality is given, there is a high possibility that the gaming machine will enter the jackpot state at the timing when the jackpot symbol random number X is an even value (see FIG. 6A). ), There is a high possibility that the first half numerical value [1, 2, 3, 4, 5] is selected as the big hit symbol. Conversely, in the gaming machine provided with the second personality, there is a slight possibility that the jackpot symbol random number X becomes a jackpot at the timing when the jackpot symbol random number X is an odd value (FIG. 6 (b)). It is highly likely that the latter half numerical value [6, 7, 8, 9, *] is selected as the big hit symbol.
[0050]
In any case, if such a big hit is in progress, processing for the operation of the first-class special electric accessory such as the special winning opening is performed (ST44). In the symbol control board, the symbol change operation is thereafter started.However, as the reach symbol in the winning state, either the first half symbol or the second half symbol easily appears, for example, the first half value is set to red. By adopting a configuration in which the latter half value is drawn in blue, the personality of the gaming machine can be further clarified.
[0051]
Thereafter, the register saved in the process of step ST30 is restored (ST45), and the interrupt process is terminated. As a result, the process normally returns from the interrupt processing routine to the infinite loop processing (ST17 to ST20) of the main routine.
[0052]
As described above, in the present embodiment, the command transmission process is divided into a first group of control commands and a second group of control commands, and the control commands are alternately transmitted. Is followed by a switch input process. Therefore, regardless of the type and bit length of the control command to be transmitted, the burden on the main control board does not increase, and a gaming machine with individuality can be realized.
[0053]
Then, the ball game machine to which the present invention is suitably applied will be described in a confirming manner. FIG. 7 is a perspective view showing the pachinko machine 22 of the present embodiment, and FIG. 8 is a side view of the pachinko machine 22. A plurality of pachinko machines 21 are provided in the length direction of the island structure of the pachinko hall in a state of being electrically connected to the card-type ball lending machine 22.

The illustrated pachinko machine 21 includes a rectangular frame-shaped wooden outer frame 23 detachably attached to the island structure, and a front frame 24 pivotally attached to be openable and closable via a hinge H fixed to the outer frame 23. It is composed of A game board 25 is detachably mounted on the front frame 24 from the back side, and a glass door 26 and a front plate 27 are pivotally mounted on the front side so as to be openable and closable, respectively.
[0055]
An upper plate 28 for storing game balls for firing is mounted on the front plate 27, and a lower plate 29 for storing game balls overflowing or extracted from the upper plate 28, and a firing handle 30 below the front frame 24. Are provided. The firing handle 30 is linked with a firing motor, and a game ball is fired by a hitting hammer 31 (see FIG. 10) that operates according to the rotation angle of the firing handle.
[0056]
On the right side of the upper plate 28, an operation panel 32 for ball lending operation for the card-type ball lending machine 22 is provided. The operation panel 32 has a card balance display section 32a for displaying the card balance with three-digit numbers. And a ball lending switch 32b for instructing lending of a predetermined amount of game balls, and a return switch 32c for instructing return of a card at the end of the game. On the upper part of the glass door 26, a big hit LED lamp P1 indicating a big hit state is arranged. Further, near the big hit LED lamp P1, abnormality notification LED lamps P2 and P3 indicating a replenishment state or a full state of the lower plate are provided.
[0057]
As shown in FIG. 8, the game board 25 is provided with an annular guide rail 33 composed of an outer rail and an inner rail made of metal, and a display by a liquid crystal color display is provided substantially in the center of the inner game area 25a. The device 8 is arranged. A symbol starting port 35, a special winning opening 36, a plurality of normal winning openings 37 (four to the left and right of the special winning opening 36), and two gates 38, which are two passing openings, are provided at appropriate places in the game area 25a. Have been. Each of the winning ports 35 to 38 has a detection switch inside so that the passage of a game ball can be detected.
[0058]
The display device 8 is a device that variably displays a specific symbol related to the big hit state and displays a background image, various characters, and the like in an animated manner. The display device 8 has special symbol display portions Da to Dc at the center and a normal symbol display portion 39 at the upper right. The normal symbol display section 39 displays a normal symbol. When a game ball passing through the gate 38 is detected, the displayed normal symbol fluctuates for a predetermined time, and is extracted when the game ball passes the gate 38. A stop symbol determined by the selected random number for lottery is displayed and stopped.
[0059]
The symbol starting port 35 is configured, for example, to be opened and closed by an electric tulip having a pair of left and right opening and closing claws 35a, and is normally opened and closed when the stopped symbol after the fluctuation of the symbol display section 39 hits and displayed. The claw 35a is opened for a predetermined time. When a game ball wins in the symbol starting port 35, the display symbols in the special symbol display sections Da to Dc fluctuate for a predetermined time, and are determined based on a lottery result according to a timing of winning the game ball to the symbol starting port 35. Stop at the stop symbol.
[0060]
The large winning opening 36 is controlled to be opened and closed by, for example, an openable and closable plate 36a that can be opened forward. When the stop symbol after the symbol change of the special symbol display portions Da to Dc is a jackpot symbol such as “777”, the “big hit” is set. Is started, and the open / close plate 36a is opened. There is a specific area 36b inside the special winning opening 36, and when a winning ball passes through the specific area 36b, a special game advantageous to the player is continued.
[0061]
After a predetermined time has elapsed after the opening and closing plate 36a of the special winning opening 36 has been opened, or when a predetermined number (for example, 10) of game balls have won, the opening and closing plate 36a closes. At this time, if the game ball does not pass through the specific area 36b, the special game is terminated. However, if the game ball passes through the specific area 36b, the special game is continued up to, for example, 16 times, which is advantageous to the player. It is controlled to the state. Furthermore, when the stopped symbol after the change is a special state occurrence symbol among the special symbols, a special state is generated.
[0062]
One of the following is suitable as an example of the special state. That is, (1) a special symbol high probability state in which the probability that the stopped symbol after the symbol change in the special symbol display section becomes a big hit symbol such as “777” is higher than in the non-special state, Compared to the special state, the large winning opening opening time is extended to increase the opening time of the special winning opening so that a larger number of gaming balls can be easily won, and (3) the gaming balls are compared to the non-special state. In order to easily win more prizes, the number of times of opening the special prize opening is increased so that the number of opening of the special prize opening is increased. Ordinary symbol that increases the probability that a stopped symbol after a symbol change in the ordinary symbol display section becomes a hit symbol, as compared to the case of the large winning opening opening amount that increases the opening amount of the mouth or (5) the non-special state. The game ball is better than in the high probability state or (6) non-special state. The number of times the electric tulip is opened so that more game balls can be easily won than in the case of an extended electric tulip opening time in which the open time of the electric tulip is extended so as to make it easier to win or (7) a non-special state. (8) An electric tulip opening amount increasing state in which the opening amount of the electric tulip is increased so that a larger number of game balls can be easily won than in the non-special state. ) Special symbol fluctuation shortened state in which the fluctuation time of the special symbol is shortened compared to the case of non-special state, and (10) effective stop line increase in which the number of effective stop lines of the special symbol is increased compared to the case of non-special state There may be a state or a normal symbol fluctuation shortened state in which the fluctuation time of the normal symbol is reduced as compared with the case of (11) the non-special state.
[0063]
Any one of these may be combined, and the generated special state is preferably terminated when a predetermined condition is satisfied. Here, the predetermined condition is the symbol change of the special symbol display unit for a predetermined number of times, the symbol change of the normal symbol display unit for a predetermined number of times, the lapse of a predetermined time, when the predetermined symbol is stopped and displayed after the symbol change of the normal symbol display unit, Typically, when a predetermined symbol is stopped and displayed after the symbol is changed in the special symbol display section, when a game ball wins a predetermined winning opening, when a game ball passes a predetermined gate, and the like.
