BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a variable display device capable of variably displaying identification information, and a player is provided on condition that the display result of the identification information on the variable display device is a predetermined specific display mode. The present invention relates to a gaming machine such as a pachinko gaming machine that can be controlled in a specific gaming state that is advantageous for

[0002]

2. Description of the Related Art As a game machine, a game medium such as a game ball is launched into a game area by a launching device, and when a game medium is won in a prize area such as a winning opening provided in the game area, a predetermined number of prize balls are provided. There are things that are paid out to the player.
Further, a variable display device whose display state can be changed is provided, and a variable display is performed on the variable display device in response to a start winning, and when a display result on the variable display device becomes a predetermined specific display mode, a predetermined display mode is set. Some are configured to give a player a gaming value.

The gaming value means that the state of the variable winning ball device provided in the gaming area of the gaming machine is advantageous for a player who easily wins a hit ball, or is advantageous for the player. To generate the right to pay for the prize, and to make it easier for the conditions for paying out prize balls to be met.

In the pachinko gaming machine, it is usually called "big hit" that the display result of the variable display device for displaying the special symbol becomes a predetermined specific display mode. When a big hit occurs, for example, the big winning opening is opened a predetermined number of times, and a big hit game state in which a hit ball is easy to win is entered. And
In each opening period, when a predetermined number (for example, 10) of winning holes are won, the winning holes are closed. The number of times the special winning opening is opened is fixed to a predetermined number (for example, 16 rounds). An opening time (for example, 29.5 seconds) is determined for each opening, and the special winning opening is closed when the opening time elapses even if the number of winnings does not reach a predetermined number. Also,
When a predetermined condition (for example, winning in the V zone provided in the special winning opening) is not established when the special winning opening is closed, the big hit game state ends.

While the variable display is being displayed on the variable display device, and in the big hit game state, the next variable display cannot be started. Therefore, the starting winning that occurred during that time is held (stored).

Whether or not to generate a big hit as a predetermined display mode of the display result of the variable display device for displaying a special symbol is generally to generate a random number,
It is performed by comparing the generated random number value with the determination value for the jackpot determination. Then, the random number is generated when the start winning occurs, and when the variable display can be started, the random number is compared with the determination value for the big hit determination.

[0007]

Therefore, it is necessary to store the random number value in the storage means such as the RAM in the state where the start winning is suspended. Then, when the number of start-up memories that can be held is large, the size of the storage area for storing the random number value must be increased. However, since the RAM capacity that can be installed in the game machine is limited, the size of the storage area cannot be increased without limit. That is, even if an attempt is made to increase the upper limit of the number of start-up memories that can be held, the upper limit is limited.

Therefore, an object of the present invention is to provide a gaming machine capable of increasing the upper limit of the number of start-up memories that can be reserved by reducing the size of the memory area for storing random numbers. To do.

Below the hitting ball supply tray 3, there are provided a surplus ball receiving tray 4 for storing game balls that cannot be accommodated in the hitting ball supply tray 3 and a ball hitting handle (operation knob) 5 for launching the game ball. A game board 6 is detachably attached to the back surface of the glass door frame 2. The game board 6 is a structure including a plate-shaped body that constitutes the game board 6 and various parts attached to the plate-shaped body. A game area 7 is formed on the front surface of the game board 6.

In the vicinity of the center of the game area 7, a variable display device (special symbol display device) 9 including a plurality of variable display portions for variably displaying symbols as identification information is provided. The variable display device 9 includes, for example, “left”, “middle”,
There are three "right" variable display parts (symbol display areas).
In addition, the variable display device 9 is provided with eight special symbol start memory display areas (start memory display areas) 18 for displaying the number of effective winning balls that have entered the start winning opening 14, that is, the number of start memory (start winning memory number). Has been. Each time there is an effective start prize, the display color is changed (for example, changed from blue display to red display) and the start memory display area is increased by one. Then, each time the variable display of the variable display device 9 is started, the number of display areas of the starting memory in which the display color is changed is reduced by 1 (that is, the display color is returned to the original one).

In this example, since the symbol display area and the starting memory display area are provided separately, the number of starting memories can be displayed even during variable display. The start memory display area may be provided in a part of the symbol display area. In this case, the display of the start memory number may be interrupted during the variable display. Also, in this example, the start memory display area is the variable display device 9
However, the display device (special symbol starting memory display device) for displaying the starting memory number may be provided separately from the variable display device 9. Furthermore, when providing a start memory display area in the display area of the variable display device 9, a start memory display area for displaying the number of start memories as a number may be provided.

Below the variable display device 9, the start winning opening 1

The entered winning balls are detected by the V winning switch 22, and the winning balls from the opening / closing plate 20 are detected by the count switch 23. On the back surface of the game board 6, a solenoid 21A for switching the route inside the special winning opening is also provided.

When the game ball wins the gate 32 and is detected by the gate switch 32a, the variable display of the display on the normal symbol display 10 is started. In this embodiment, the left and right lamps (the pattern can be visually recognized when turned on) are alternately turned on to perform variable display. For example, when the variable display ends, the right lamp is turned on. And when the stop symbol on the normal symbol display 10 is a predetermined symbol (hit symbol), the variable winning ball device 15 is opened for a predetermined number of times and for a predetermined time. Normal symbol display 10
The number of winning balls that entered the gate 32 is displayed near 4
A normal symbol start-up memory display 41 having a display section with two LEDs is provided. Every time there is a prize in the gate 32, the normal symbol starting memory display 41 turns on the LED that is turned on by 1

The game board 6 has a plurality of winning openings 29, 30,
33, 39 are provided, and the winning openings 29, 30, 3 for gaming balls
The prizes for 3 are prize winning opening switches 29a, 30 respectively.
a, 33a, 39a. Each prize hole 2
Reference numerals 9, 30, 33, and 39 form a winning area provided on the game board 6 as an area for accepting a game medium and allowing a prize. It should be noted that the starting winning opening 14 that accepts the game medium and allows the winning, and the special winning opening also constitute the winning area. Decorative lamps 25 that are displayed blinking during the game are provided around the left and right sides of the game area 7, and an outlet 26 that absorbs a game ball that has not won is provided in the lower part. In addition, two speakers 27 that emit a sound effect are provided on the upper left and right sides outside the game area 7. On the outer periphery of the game area 7, a top frame lamp 28a, a left frame lamp 28b and a right frame lamp 2
8c is provided. Further, a decorative LED is installed around each structure (a special winning opening, etc.) in the game area 7. The top frame lamp 28a, the left frame lamp 28b, the right frame lamp 28c, and the decorative LED are examples of the decorative light-emitting body provided in the game machine.

In this example, the prize ball lamp 51 that lights up when there is a remaining number of prize balls near the left frame lamp 28b.
Is provided, and a ball-out lamp 52 that is turned on when the supply ball runs out is provided near the top frame lamp 28a.
As described above, the pachinko gaming machine 1 of this embodiment is provided with the lamps and the LEDs as the light emitting bodies at various places. Further, FIG. 1 also shows a card unit 50 which is installed adjacent to the pachinko gaming machine 1 and enables a ball lending by inserting a prepaid card.

The card unit 50 has a usable indicator lamp 151 for indicating whether or not it is in an usable state, and a connecting board direction indicator for indicating which side of the pachinko gaming machine 1 the card unit 50 corresponds to. 153, a card insertion indicator lamp 154 indicating that a card has been inserted into the card unit 50, a card insertion slot 155 into which a card as a recording medium is inserted, and a card reader provided on the back surface of the card insertion slot 155. A card unit lock 156 is provided for releasing the card unit 50 when checking the mechanism of the writer.

The game ball shot from the hitting ball launching device enters the game area 7 through the hit ball rail, and then comes down from the game area 7. When the game ball enters the starting winning opening 14 and is detected by the starting opening switch 14a, if the variable display of the symbol can be started, the variable display device 9 starts the variable display (variation) of the special symbol. If it is not in a state where variable display of symbols can be started, the number of starting memories is increased by 1.

The variable display of the special symbol on the variable display device 9 is stopped when a certain time has elapsed. If the special symbol combination at the time of stop is a big hit symbol (specific display result), the big hit game state is entered. That is, the opening / closing plate 2
0 is released until a certain time has elapsed or a predetermined number (for example, 10) of game balls are won. And
When the game ball enters the V winning area and is detected by the V winning switch 22 while the opening / closing plate 20 is open, the continuation right is generated and the opening / closing plate 20 is opened again. The continuation right can be generated a predetermined number of times (for example, 15 rounds).

A combination of special symbols in the variable display device 9 at the time of stop is a big hit symbol with a probability variation (probability variation symbol)
If, then there is a higher probability of a big hit next. That is, the state of probability change is more advantageous for the player.

When the game ball wins the gate 32, the normal symbol display 10 is in a state in which the normal symbol is variably displayed. Further, when the stop symbol in the normal symbol display 10 is a predetermined symbol (hit symbol), the variable winning ball device 1
5 is opened only for a predetermined time. Furthermore, in the probability variation state, the probability that the stop symbol in the normal symbol display 10 will be a winning symbol is increased, and the opening time and the number of times of opening the variable winning ball device 15 are increased. That is, the opening time and the number of times of opening the variable winning ball device 15 are increased when the stop symbol of the normal symbol is a winning symbol or the stop symbol of the special symbol is a probability variation symbol, and the like, and from a disadvantageous state for the player. Change to an advantageous state. In addition, increasing the number of times of opening is a concept including changing from a closed state to an open state.

FIG. 3 is a block diagram showing an example of the circuit configuration of the main board 31. Note that FIG. 3 also shows the payout control board 37 and the effect control board 80. On the main board 31, a basic circuit 53 for controlling the pachinko gaming machine 1 according to a program, a gate switch 32a, a starting opening switch 14a, a V winning switch 22, a count switch 23, winning opening switches 29a, 30a, 33a, 39.
a and a switch circuit 58 for giving a signal from the clear switch 921 to the basic circuit 53, and the variable winning ball device 15
A solenoid 16 for opening and closing, a solenoid 21 for opening and closing the opening and closing plate 20, and a solenoid circuit 59 for driving a solenoid 21A for switching the path in the special winning opening according to a command from the basic circuit 53 are mounted.

Although not shown in FIG. 3, the count switch short circuit signal is also transmitted to the basic circuit 53 through the switch circuit 58. Further, the gate switch 32a, the starting port switch 14a, the V winning switch 22, the count switch 23, the winning port switches 29a, 30a, 33a,
The switch such as 39a may be what is called a sensor. That is, any name may be used as long as it is a game medium detecting means (a game ball detecting means in this example) capable of detecting a game ball. In particular, the starting opening switch 14a for detecting the winning a prize,
The count switch 23 and the winning opening switch 29a,
The switches 30a, 33a, and 39a are also winning detection means. The winning detection means may be one that collectively detects each of the gaming balls that have been won separately in a plurality of winning openings. Further, even if a passing gate such as the gate switch 32a is used for paying out prize balls, entering a game ball into the passing gate is a prize, and a switch provided in the passing gate (for example, The gate switch 32a) serves as a winning detection means.

Further, according to the data given from the basic circuit 53, the big hit information indicating the occurrence of the big hit, the effective starting information indicating the number of the starting winning balls used to start the variable display of the symbols on the variable display device 9, and the probability variation. An information output circuit 64 that outputs an information output signal such as probability variation information indicating that it has occurred to an external device such as a hall computer is mounted.

The basic circuit 53 is a ROM 54 for storing a program for controlling a game, and R as a storage means (means for storing variation data) used as a work memory.
AM55, CPU5 which controls according to the program
6 and I / O port section 57. In this embodiment, the ROM 54 and the RAM 55 are built in the CPU 56. That is, the CPU 56 is a one-chip microcomputer. The one-chip microcomputer only needs to have at least the RAM 55 built therein, and the ROM 5
4 and the I / O port section 57 may be external or built-in. Since the CPU 56 executes control according to the program stored in the ROM 54, hereinafter, the CPU 56 executes (or performs processing) specifically means that the CPU 56 executes control according to the program. is there. This means that the main substrate 31
The same applies to CPUs mounted on boards other than the above.

The RAM 55 (which may be a CPU built-in RAM) 55 is partially or wholly power supply board 91.
It is a backup RAM that is backed up by a backup power supply created at 0. That is, even if the power supply to the gaming machine is stopped, part or all of the contents of the RAM 55 are saved for a predetermined period.

A power supply monitoring circuit 920 is mounted on the main board 31. The power supply monitoring IC 902 is a power supply board 91.
The VSL voltage (DC + 30V) from 0 is introduced, and the occurrence of the power supply stop to the gaming machine is detected by monitoring the VSL voltage. Specifically, when the VSL voltage becomes equal to or lower than a predetermined value (+ 22V in this example), the power supply cutoff signal is output (specifically, it is set to a low level). The power-off signal is input to the non-maskable interrupt terminal of the CPU 56. When the power-off signal is input to the non-maskable interrupt terminal, the non-maskable interrupt is applied, and the power supply stop process is executed as the non-maskable interrupt process. CP
U56 is a backup RAM for necessary information (information necessary for continuing the game process from the state when the power supply is stopped when the power supply is restored) in the power supply stop processing.
A process for surely storing the data (for example, a parity data setting process) is executed. Further, a flag indicating that the power supply stop processing has been performed is set.

The hit ball launching device for hitting and launching a game ball is driven by a drive motor 94 controlled by a circuit on the launch control board 91. Then, the driving force of the drive motor 94 is adjusted according to the operation amount of the operation knob 5. That is, the circuit on the launch control board 91 controls the game ball to be launched at a speed according to the operation amount of the operation knob 5.

In this embodiment, the effect control means mounted on the effect control board 80 controls the display of the normal symbol start memory display 41 and the decorative lamp 25 provided on the game board, Display control of the top frame lamp 28a, the left frame lamp 28b, and the right frame lamp 28c provided on the frame side is performed. The production control means mounted on the production control board 80 also controls the display of the variable display device 9 that variably displays the special symbol and the ordinary symbol display 10 that variably displays the ordinary symbol.

Next, the operation of the gaming machine will be described. Figure 4
Is a flowchart showing main processing executed by the game control means (CPU 56 and peripheral circuits such as ROM and RAM) on the main board 31. When power is turned on to the gaming machine and the input level of the reset terminal becomes high level, the CPU 56 starts the main processing after step S1. In the main process, the CPU 56 first makes necessary initial settings.

In the initial setting process, the CPU 33 first sets the interrupt prohibition (step S1). Next, the interrupt mode is set to interrupt mode 2 (step S
2) The stack pointer designated address is set in the stack pointer (step S3). Then, the built-in device register is initialized (step S4). After initializing the CTC (counter / timer circuit) and PIO (parallel input / output port) which are built-in devices (built-in peripheral circuits) (step S5), the RAM 55 is set to the accessible state (step S6). . In the interrupt mode 2, the address composed of the value (1 byte) of the specific register (I register) built in the CPU 33 and the interrupt vector (1 byte: least significant bit 0) output by the built-in device is the interrupt address. This is the mode shown.

Next, the CPU 56 confirms the state of the output signal of the clear switch 921 inputted via the input port 1 only once (step S7). If ON is detected in the confirmation, the CPU 56 executes normal initialization processing (steps S11 to S1).
5). When the clear switch 921 is on (when pressed), a low level clear switch signal is output. In the input port 1, the on state of the clear switch signal is high level. Further, for example, the game shop staff can easily execute the initialization process by starting power supply to the gaming machine (for example, turning on the power switch 914) while turning on the clear switch 921. That is, the RAM clear or the like can be performed.

If the clear switch 921 is not in the ON state, data protection processing of the backup RAM area (for example, processing when power supply is stopped such as addition of parity data) is performed when power supply to the gaming machine is stopped. It is confirmed whether or not (step S8). In this embodiment, when the power supply is stopped, a process for protecting the data in the backup RAM area is performed. When such a protection process is performed, backup is made. When it is confirmed that such protection processing is not performed, the CPU 56 executes initialization processing.

In this embodiment, the backup RAM
Whether or not there is backup data in the area is confirmed by the state of the backup flag set in the backup RAM area during the power supply stop process. For example, if "55H" is set in the backup flag area, it means that there is backup (on state), and "55H"
If a value other than "H" is set, it means that there is no backup (off state).

After confirming that there is a backup, the CPU 5
6 performs a data check of the backup RAM area (parity check in this example) (step S9). In this embodiment, clear data (00) is set in the checksum data area, and the checksum calculation start address is set in the pointer. Further, the number of checksum calculations corresponding to the number of checksum target data is set. Then, the exclusive OR of the contents of the checksum data area and the contents of the RAM area indicated by the pointer is calculated. The calculation result is stored in the checksum data area, the pointer value is incremented by 1, and the checksum calculation count value is decremented by 1. The above process is repeated until the value of the checksum calculation count becomes zero. When the value of the checksum calculation count becomes 0, the CPU 56 inverts the value of each bit of the contents of the checksum data area,
The data after inversion is used as the checksum.

In the power supply stop process, the checksum is calculated by the same process as the above process, and the checksum is stored in the backup RAM area. In step S9, the calculated checksum is compared with the stored checksum. If the power is restored after an unexpected power outage such as a power outage, backup RA
Since the data in the M area should have been saved, the check result (comparison result) becomes normal (match). If the check result is not normal, it means that the data in the backup RAM area is different from the data when the power supply was stopped. In such a case, since the internal state cannot be returned to the state when the power supply was stopped, the initialization process that is executed when the power is turned on is performed when the power supply is not restored.

If the check result is normal, the CPU 56
Performs a game state recovery process for returning the internal state of the game control means and the control state of the electric component control means such as the effect control means to the state at the time of stopping the power supply (step S10). Then, the saved value of the PC (program counter) saved in the backup RAM area is set in the PC and the address is restored.

In the initialization process, the CPU 56 first reads R
AM clear processing is performed (step S11). RA
The predetermined data (for example, the data of the count value of the counter for generating the big hit determination random number) may be left as it is without initializing the entire area of M55. For example, when the data of the count value of the counter for generating the big hit determination random number is left as it is, the big hit determination random number is generated even if the initialization process is executed by an unauthorized means. It is difficult to aim at a timing when the count value of the counter coincides with the jackpot determination value.
In addition, a predetermined work area (for example, a random number counter for normal symbol determination, a normal symbol determination buffer, a special symbol left middle right symbol buffer, a total prize ball number storage buffer, a special symbol process flag, a prize ball medium flag, a ball out flag , A payout stop flag and other flags for selectively performing processing according to the control state)
A work area setting process for setting an initial value to is performed (step S12).

Further, the CPU 56 executes a process of transmitting an initialization command for initializing the effect control board 80 to the effect control board 80 (step S14). As the initialization command, there is a command or the like indicating the initial symbol displayed on the variable display device 9.

Then, the register of the CTC provided in the CPU 56 is set so that the timer interrupt is periodically applied every 2 ms (step S15). That is,
A value corresponding to 2 ms as an initial value is set in a predetermined register (time constant register).

Execution of initialization processing (steps S11 to S1)
When 5) is completed, the display random number updating process (step S17) and the initial value random number updating process (step S18) are repeatedly executed in the main process. When the display random number updating process and the initial value random number updating process are executed, the interrupt disabled state is set (step S16), and when the display random number updating process and the initial value random number updating process are completed, the interrupt enabled state is set. (Step S19). The display random number is a random number for determining the symbol displayed on the variable display device 9, and the display random number updating process is a process of updating the count value of the counter for generating the display random number. . The initial value random number updating process is a process of updating the count value of the counter for generating the initial value random numbers. The initial value random number is a random number for determining an initial value of a count value of a counter (big hit determination random number generation counter) for generating a random number for determining whether or not to make a big hit. In the game control process described later, when the count value of the big hit determination random number generation counter makes one round, the initial value is set to the counter.

When a timer interrupt occurs, the CPU 56
After performing the register save process (step S20), the game control process of steps S21 to S32 shown in FIG. 5 is executed. In the game control process, the CPU 56 first inputs the detection signals of the switches such as the gate switch 32a, the starting opening switch 14a, the count switch 23, and the winning opening switches 29a, 30a, 33a, 39a via the switch circuit 58, Those states are determined (switch processing: step S21).

Next, various abnormality diagnosis processing is performed by the self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error processing: step S22).

Next, a process of updating the count value of each counter for generating each judgment random number such as a big hit judgment random number used for game control is performed (step S23).
The CPU 56 further performs a process of updating the count value of the counter for generating the display random number and the initial value random number (steps S24 and S25).

FIG. 6 is an explanatory diagram showing each random number. It is explanatory drawing which shows each random number. Each random number is used as follows. (1) Random 1: Decide whether to generate a big hit (for big hit judgment) (2) Random 2-1 to 2-3 (Random 2): For left edge middle right of special symbol Determining symbol (special symbol) Left middle right) (3) Random 3: Determine the combination of special symbols that generate a big hit (for big jack symbol determination) (4) Random 4: Determine the variation pattern of special symbols (for variation pattern determination) (5) Random 5: Determine whether or not to reach when big hit does not occur (for reach determination) (6) Random 6: Determine whether or not to generate hits based on ordinary symbols (for ordinary symbol hit determination) ( 7) Random 7: Determine initial value of random 1 (for determining random 1 initial value) (8) Random 8: Determine initial value of random 6 (for determining random 6 initial value)

At step S23 in the game control process shown in FIG. 5, the CPU 56 determines the random number for jackpot determination in (1), the random number for determining jackpot symbol in (3), and the random number for regular symbol hit determination in (6). The counter is incremented (added by 1) to generate. That is, those are the judgment random numbers, and the other random numbers are the display random numbers or the initial value random numbers. In addition, in order to enhance the game effect,
Random numbers related to ordinary symbols other than the above random numbers (1) to (8) are also used.

Further, the CPU 56 carries out special symbol process processing (step S26). In the special symbol process control, the corresponding process is selected and executed according to the special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to the gaming state. Then, the value of the special symbol process flag is updated during each process according to the game state. Also, a normal symbol process process is performed (step S27). In the normal symbol process process, the corresponding process is selected and executed according to the normal symbol process flag for controlling the display state of the normal symbol display device 10 in a predetermined order. And the value of the normal symbol process flag,
It is updated during each process according to the game state.

Next, the CPU 56 performs a process of setting the effect control command relating to the special symbol in a predetermined area of the RAM 55 and transmitting the effect control command (special symbol command control process: step S28). Moreover, the process of sending the production control command by setting the production control command relating to the ordinary symbol in a predetermined area of the RAM 55 (ordinary symbol command control process: step S29).

Further, the CPU 56 performs an information output process for outputting data such as big hit information, starting information, probability variation information, etc. supplied to the hall management computer (step S30).

Further, the CPU 56 issues a drive command to the solenoid circuit 59 when a predetermined condition is satisfied (step S31). In order to open or close the variable winning ball device 15 or the opening / closing plate 20 or to switch the game ball passage in the special winning opening, the solenoid circuit 59 drives the solenoids 16, 21, 21A according to the drive command. To do.

Then, the CPU 56 causes the winning opening switch 2
A prize ball process is performed for setting the number of prize balls based on the detection signals of 9a, 30a, 33a and 39a (step S32). Specifically, the winning opening switches 29a, 30
In response to the winning detection based on that a, 33a, 39a are turned on, a control signal such as a payout number signal indicating the number of prize balls is output to the payout control board 37. The payout control CPU 371 mounted on the payout control board 37 drives the ball payout device 97 in response to a control signal such as a payout number signal indicating the number of prize balls. After that, the contents of the register are restored (step S33), and the interrupt enabled state is set (step S3).
4).

By the above control, in this embodiment, the game control process is activated every 2 ms.
In this embodiment, the game control process is executed in the timer interrupt process, but in the timer interrupt process, for example, only a flag indicating that an interrupt has occurred is set,
The game control process may be executed in the main process.

FIG. 7 is a flow chart showing an example of a special symbol process processing program executed by the CPU 56. The special symbol process process shown in FIG. 7 is a specific process of step S26 in the flowchart of FIG. CPU56, when performing the special symbol process processing,
The fluctuation reduction timer subtraction process (step S310) is performed,
If the starting opening switch 14a for detecting that the game ball has won in the starting winning opening 14 provided in the game board 6 is turned on, that is, the starting winning in which the gaming ball enters the starting winning opening 14 occurs. If so (step S311),
After performing the starting opening switch passage process (step S312), steps S300 to S308 are performed according to the internal state.
One of the above is performed. The fluctuation reduction timer is a timer for setting the fluctuation time when the fluctuation time of the special symbol is shortened.

Special symbol normal processing (step S300):
Wait until the variable display of special symbols can be started.
When the variable display of special symbols can be started, check the number of starting memories. If the starting memory number is not 0, as a result of the variable display of the special symbol, it is determined whether or not to make a big hit. Then, the internal state (special symbol process flag) is step S
Update to move to 301.

Special symbol stop symbol setting process (step S3
01): The stop symbol of the left middle right symbol after the variable display of the special symbol is determined. Then, the internal state (special symbol process flag) is updated so as to shift to step S302.

Fluctuation pattern setting process (step S30)
2): The variation pattern (variable display mode) of the variable display of the special symbol is determined according to the value of Random 4. Also, the variable time timer is started. At this time, to the effect control board 80, the left middle right final stop symbol and the information instructing the variation mode (variation pattern) are transmitted. Then, the internal state (special symbol process flag) is updated so as to shift to step S303.

Special symbol variation process (step S303):
When a predetermined time (time indicated by the variable time timer in step S302) elapses, the internal state (special symbol process flag) is updated so as to shift to step S304.

Special symbol stop processing (step S304):
Control is performed so that all symbols displayed on the variable display device 9 are stopped. Specifically, the display control command indicating the stop of the special symbol is set to be transmitted. Then, when the stop symbol is a combination of big hit symbols, the internal state (special symbol process flag) is updated so as to shift to step S305. If not, the internal state is updated to shift to step S300.

Special winning opening opening processing (step S30
5): Start control for opening the special winning opening. Specifically, the counter and the flag are initialized, and the solenoid 21 is driven to open the special winning opening. Also, the process timer sets the execution time of the special winning opening opening process, and sets the big hit flag. Then, the internal state (special symbol process flag) is updated so as to shift to step S306.

Processing during the opening of the special winning opening (step S30
6): The control for sending the display control command of the special winning opening round display to the effect control board 80, the processing for confirming the establishment of the closing condition of the special winning opening, and the like are performed. When the closing condition for the last special winning opening is satisfied, the internal state is updated so as to shift to step S307.

Specific area effective time processing (step S30
7): The presence or absence of passage of the V winning switch 22 is monitored, and the processing for confirming the establishment of the jackpot gaming state continuation condition is performed. If the conditions for continuation of the jackpot gaming state are met and there are still remaining rounds, the internal state is updated so as to shift to step S305. If the jackpot gaming state continuation condition is not satisfied within a predetermined effective time, or if all the rounds are finished, the internal state is set to step S.
Update to move to 308.

Big hit end processing (step S308): control for causing the effect control means to perform display control for notifying the player that the big hit game state has ended. Then, the internal state is updated so as to shift to step S300.

FIG. 8 is a flow chart showing the starting opening switch passage processing (step S312) executed when a start winning is generated. In the starting port switch passage processing, the CPU 56 confirms whether or not the number of stored memories for starting has reached the maximum value of 8 (step S111). If the number of starting memories has not reached 8, the number of starting memories is increased by 1 (step S112), the value of each random number such as the big hit determination random number is extracted, and these are stored in a storage area (special area) corresponding to the value of the number of starting memories. Stored in the pattern determination buffer) (step S
113). Extracting a random number means reading a count value from a counter for generating a random number and using the read count value as a random number value. In step S113, random numbers 1 to 5 are extracted from the random numbers shown in FIG.

FIG. 9 is a flowchart showing the special symbol normal process (step S300) in the special symbol process process. In the special symbol normal processing, CPU56
In the state where the variation of the special symbol can be started (for example, when the value of the special symbol process flag is the value indicating step S300) (step S51), the value of the starting memory number is confirmed (step S52). Specifically, the count value of the starting winning counter is confirmed. In addition,
The case where the value of the special symbol process flag is the value indicating step S300 is a case where the symbol is not changed in the variable display device 9 and the big hit game is not being performed.

If the starting memory number is not 0, the starting memory number =
Each random number value stored in the storage area corresponding to 1 is read out and stored in the random number buffer area of the RAM 55 (step S53), the value of the starting memory number is decreased by 1, and the content of each storage area is shifted. (Step S5
4). That is, the number of starting memories = n (n = 2, 3, 4,
Each random number value stored in the storage area corresponding to (5, 6, 7, 8) is stored in the storage area corresponding to the starting memory number = n-1.

Next, the CPU 56 reads the big hit determination random number from the random number storage buffer (step S55),
The jackpot determination module is executed (step S56).
If it is decided to make a big hit (step S5
7), the CPU 56 sets a big hit flag (step S58). Then, the value of the special symbol process flag is updated to a value corresponding to the special symbol stop symbol setting process (step S59).

[0077]

FIG. 10 is an explanatory diagram showing an example of the big hit judging table used in the big hit judging module. As shown in FIG. 10, in this embodiment, the big hit determination values are “53” and “523” at the time of low probability (at the time of uncertain variation), and the big hit determination value is “3” at the time of high probability (at the time of certain variation). ",
"17", "31", "53", "263", "28"
2 "," 307 "," 523 "," 547 "," 57 "
1 ". All numerical values are prime numbers. Therefore,
They are relatively prime (neither number is divisible by the other). In this way, by setting the big hit determination values to be relatively prime, it is possible to prevent a situation in which the random 1 and the big hit determination value match at a constant cycle.

FIG. 11 is a flowchart showing the big hit judging module. CPU in the jackpot determination process
First, 56 determines whether or not the state at that time is undergoing probable variation (step S141).
It is determined to use the jackpot determination table at the time of probability change shown in (B) (step S142). If the probability change is not in progress, it is determined to use the big hit determination table at the time of non-probability change shown in FIG. 10A (step S14).
3).

Then, it is determined whether or not there is a value matching the extracted random 1 value in the jackpot determination table (steps S144 and S145), and if there is a matching value, the jackpot is determined (step S146). ), If there is no matching value, it is determined not to be a big hit (step S147).

FIG. 12 shows the step S11 shown in FIG.
It is explanatory drawing for demonstrating the method of storing the random 1 (random number for big hit determination) among the random numbers saved in the storage area (special symbol determination buffer) in 3. Random 1
Is a counter (random 1
It is generated by reading the count value of the generation counter), but the counter is a 2-byte counter because one byte cannot count 256 or more. When the CPU 56 reads the count value of the counter and generates Random 1, it determines whether or not the value of Random 1 matches any of the big hit determination values set in the big hit determination table.

The jackpot judgment value is shown in FIG.
2 is a numerical value as shown in the column of “binary number display”, and both bits 6 and 7 (bit 0 on the rightmost side of the binary number display shown in FIG. 12 and bit 9 on the leftmost side) are both It is 0 ". Although FIG. 12 shows the random 1 that matches the jackpot determination value, the binary display of the jackpot determination value is, of course, the same as the numerical value of the binary display shown in FIG.

If the value of Random 1 matches any of the big hit judgment values set in the big hit judgment table, the CPU 56 generates bits 6, 7 of the random 1.
Is deleted and bits 8 and 9 are set to the positions of bits 6 and 7. By such processing, the number of bits of random 1 is compressed to 8 bits (1 byte). Therefore, random 1 saved in the save area (special symbol determination buffer)
The area to be assigned to (random number for jackpot determination) may be 1 byte. If no processing is performed, the area to be assigned to random 1 (random number for jackpot determination) is 2
It is a byte.

When the value of Random 1 does not match any of the big hit judging values set in the big hit judging table (in the case of being out of alignment), the CPU 56 saves it in the save area (special symbol judging buffer). “00 (H)” is set as Random 1. When it becomes possible to start the variable display on the variable display device 9, the random 1 stored in the storage area is compared with the jackpot determination value, and the display result on the variable display device 9 is a jackpot pattern (stop in the left middle right). It is determined whether or not to shift to the big hit game state as a set of symbols), but if "00 (H)" is set, it does not match any of the big hit determination values. That is, even if the process of reducing the number of bits of random 1 is performed, it is not judged as a big hit although it is originally out of sync. A value other than “00 (H)” may be used if it does not match any of the jackpot determination values.

In this embodiment, the size of the storage area for each starting memory can be reduced by 1 byte. As a result, the upper limit of the number of starting memories can be increased. In this embodiment, the upper limit value of the number of starting memories is 8, but the upper limit value of the number of starting memories may be further increased if the RAM 55 has a sufficient capacity.

The RAM area to be used is increasing with the richness and complexity of the effect contents of the gaming machine. However, in a gaming machine such as a pachinko gaming machine, a CPU including a ROM and a RAM is used as the CPU 56 for security reasons, and the RAM capacity is limited. If the upper limit value of the number of starting memories is increased, it is possible to prevent the starting memories of special symbols involved in the big hit, which are advantageous to the player, from being invalidated, and it is possible to add a new game property to the gaming machine. . However, due to the above restrictions, there is a limit to increase the upper limit of the number of starting memories. In this embodiment, the upper limit value of the number of starting memories can be made larger under the above-mentioned constraints,
A new game property can be added to the gaming machine.

The random 1 stored in the storage area (special symbol determination buffer) is read when the variable display device 9 can start variable display (step S53), and is set in the big hit determination table. It is compared with the jackpot judgment value (steps S56, S1
44) At that time, the CPU 56 sets the read random 1 bits 6 and 1 of 1 byte to the positions of bits 8 and 9, and sets both bits 6 and 7 to “0”. That is, the 2-byte random 1 is restored. And 2
Random 1 of the byte is compared with the jackpot judgment value.

The big hit judging value set in the big hit judging table (ROM) may also be stored in a compressed form of 1 byte. That is, the jackpot determination value as the predetermined determination value data may also be stored as data with the number of bits deleted. FIG. 13 shows bits 0 to
It is explanatory drawing which shows the setting value (ROM storage value) at the time of compressing the big hit determination value comprised by bit 9 (substantially 2 bytes) to 1 byte, and setting it in a big hit determination table. As shown in FIG. 13, as in the case of random 1, the jackpot determination value is set in the jackpot determination table in a form in which bits 6 and 7 are deleted.

As shown in FIG. 13, the big hit judgment value at the time of probability change is also compressed to 1 byte and set in the big hit judgment table together with the big hit judgment value at the time of non-probability change. That is, it is preferable that the predetermined determination value data in the probability improving state is also stored as data with the number of bits deleted. When the big hit judgment value is compressed to 1 byte and set in the big hit judgment table, the amount of use of the ROM 54 can be saved, but since the number of big hit judgment values at the time of probability change is large, the big hit judgment value at the time of probability change is set to 1 By compressing the data into bytes and setting it in the jackpot determination table, the effect of ROM saving becomes greater.

In game machines such as pachinko machines, ROM5
Since the security check program for authenticity check 4 is also stored in the ROM 54, there is a limit to the ROM area that can be used as the game control program. However, in the present invention, the amount of use of the ROM 54 can be reduced, so that the area for storing the game control program can be increased and the game effect can be enriched.

When the jackpot determination value is compressed to 1 byte and set in the jackpot determination table, the bit of the jackpot determination value read from the jackpot determination table in step S113 executed when the start winning is generated. Bits 6, 7 are moved to bits 8, 9 and bit 6,
After setting both "0" to 7, the count value of the counter (2 bytes) for generating random 1 (that is, random 1 before data compression) is compared, and if they do not match, the storage area ( "00 (H)" is set as random 1 in the special symbol determination buffer), and if there is a match, random 1 compressed to 1 byte is set.

It becomes possible to start the variable display, and when the big hit judgment value set in the big hit judgment table and the random 1 (1 byte) stored in the storage area are compared, the big hit judgment value is 1 Since it is compressed into bytes and set in the jackpot determination table, the CPU 56
Can directly compare the jackpot determination value with the random 1 stored in the storage area.

FIG. 14 is a normal symbol process process (step S2) executed in the game control process shown in FIG.
7 is a flowchart showing 7). In the normal symbol process process, the CPU 56 executes one of the processes shown in steps S72 to S76 according to the value of the normal symbol process flag after executing the gate switch process in step S71.

As shown in FIG. 15, in the gate switch process, the ON state of the gate switch 32a based on the passing of the ball at the gate 32, which is a condition for starting the symbol variation, is detected (step S611). If the gate switch 32a is turned on, it is confirmed whether or not the normal symbol starting memory has reached the maximum value ("4" in this example) (step S61).
2). If it has not reached, the value of the normal symbol starting memory is +1
Yes (step S613). The LED of the normal symbol starting memory indicator 41 is turned on according to the value of the normal symbol starting memory. Then, the CPU 56 extracts the value of the random number for random determination per normal pattern (random 5) and stores the value (S).
614). The normal symbol start memory is a backup R
It is formed in AM.

In this embodiment, the upper limit of the normal symbol starting memory is 4, whereas the upper limit of the starting memory number is
8 more than that. That is, in this embodiment, R increased by compressing the random 1 stored in the storage area (special symbol determination buffer) into 1 byte.
The empty area of AM55 is allocated to the increment of the starting memory of the special symbol which is involved in the jackpot which is advantageous to the player, and a new game property which is advantageous to the player is added.

As described above, in the above embodiment, the gaming machine updates the predetermined numerical data (the count value of the counter for generating the random 1), and the predetermined timing ( Numerical data extraction means for acquiring numerical data at the time of occurrence of a start winning prize and storing it in storage means (save area: special symbol determination buffer), numerical data stored in storage means and predetermined determination value data ( (A big hit determination value) and a game state determining means for determining whether or not to have a specific game state, and the numerical data extracting means reduces the number of bits of the acquired numerical data and stores it in the storage means. Since it is configured, it is possible to save the amount of use of the storage area, and to allocate that amount to the increase of the starting memory.

In the above embodiment, the bits 6 and 7 of the plurality of jackpot determination values are the same, so these bits could be reduced. However, the reduction of bits 6 and 7 is an example. is there. Each jackpot judgment value is relatively prime, and there are bits that have the same value when displayed in binary,
If the number of bytes can be reduced by reducing those bits, it is possible to reduce the area for storing the random 1 in the storage area (special symbol determination buffer) even if another big hit determination value is used. In other words, the jackpot determination values are disjoint and 2
There is a bit that has the same value when expressed in a decimal number, and by selecting a value that can reduce the number of bytes by reducing those bits, the area for storing the random 1 can be reduced.

Further, according to the present invention, the following modified examples can be constructed.

The upper limit value changing means included in the game control means increases the upper limit value of the starting memory number within the allowable range of the RAM capacity when the display result on the variable display device 9 becomes a big hit symbol. For example, in step 58 shown in FIG. 9, the process of changing the setting of the upper limit value is also performed.

When the display result on the variable display device 9 is a probability variation big hit symbol, or a time saving symbol for shifting to a time saving state in which the variation time of the special symbol is shortened, R
Within the allowable range of AM capacity, the upper limit value of the number of starting memories is increased.

When shifting to the special game state, the upper limit of the number of starting memories is increased within the allowable range of the RAM capacity.
Also, when returning from the special game state to the normal state, the upper limit value of the number of starting memories is restored.

When the display result on the variable display device 9 is out of order, the upper limit value of the number of starting memories is restored.

In the big hit game state, the upper limit of the number of starting memories is increased within the allowable range of the RAM capacity.

In the above embodiment, the "special game state" means a state that is advantageous to the player who is prone to a big hit. Specifically, "special game state"
Is, for example, a probability variation state in which the probability that the special symbols are arranged in a big jackpot pattern is a high probability state, a time saving state in which the number of fluctuations of the ordinary symbol per unit time is increased, and an opening period and the number of times of opening the variable winning ball device 15 are increased. It is a high-probability state in which the probability of a big hit such as the extended extension state is increased. In the time saving state, since the number of times the variable winning ball device 15 is opened is increased, the number of winnings per unit time is increased, and the number of times the special symbol is variably displayed per unit time is increased. Can be said to have been raised. Similarly, in the extended open state, the number of winnings per unit time is increased because the opening period and the number of times of opening the variable winning ball device 15 are increased, and the number of times the special symbol is displayed variable per unit time is increased. Therefore, it can be said that the probability of being a big hit is increased.

Further, the pachinko gaming machine 1 of the above-described embodiment has a predetermined game value when the stop symbol of the special symbol variably displayed on the variable display device 9 is a combination of the predetermined symbols based on the start winning. Although it was a first-class pachinko game machine that can be given to a player, a predetermined game value can be given to a player when there is a prize in a predetermined area of an electric auditors to be released based on a start prize. Seed pachinko machine,
It is a third-class pachinko game machine in which a predetermined right is generated or continues when there is a prize for a predetermined electric accessory that is released when a stop symbol that is variably displayed based on a start winning is a combination of a predetermined symbol. However, the present invention can be applied.
Further, the present invention is not limited to a pachinko game machine in which the game medium is a game ball, and the present invention can be applied to a game medium detecting means for detecting a game medium even in a slot machine such as a medal game medium.

[0106]

As described above, according to the first aspect of the invention, the gaming machine has a numerical value updating means for updating predetermined numerical value data, and a numerical value acquiring means for storing numerical value data from the numerical value updating means at a predetermined timing. Numerical data extraction means to be stored in
The numerical data extraction unit includes a display result determining unit that compares the numerical data stored in the storage unit with predetermined judgment value data to determine whether to display the specific display mode, and the numerical data extracting unit acquires the acquired numerical data. Since the numerical data compressing means for reducing the number of bits of and storing the numerical data in the storing means is included, it is possible to reduce the size of the storage area of the numerical data in the storing means, and as a result, the numerical value that can be stored in the storing means. The amount of data can be increased.

According to the second aspect of the present invention, when the numerical data compressing means determines that the acquired numerical data matches the predetermined judgment value data, the numerical data compressing means sets a bit at a predetermined position in the acquired numerical data. Since the number of bits is reduced by deleting, the reduction process can be facilitated.

According to the third aspect of the present invention, when the numerical data compression means determines that the acquired numerical data does not match the predetermined judgment value data, the specific numerical data different from the predetermined judgment value data. Is stored in the storage means, it is possible to prevent the display result determination means from erroneously determining to display the specific display mode even if the reduction processing is performed.

According to the fourth aspect of the invention, since the plurality of pieces of judgment value data are numerical data that are relatively prime, a situation in which the numerical value data and the predetermined judgment value data coincide with each other in a fixed cycle does not appear. You can

According to the fifth aspect of the present invention, since the predetermined judgment value data is stored as data with the number of bits deleted, it is possible to reduce the size of the storage area for the judgment value data.

According to the sixth aspect of the present invention, since each judgment value data in the probability improving state is stored as data with the number of bits deleted, the size of the storage area of the judgment value data can be further reduced.

According to the seventh aspect of the present invention, the upper limit value of the number of stored conditions of the variable display start stored in the start storage means is set to the upper limit of the number of stored memory of the variable display start conditions stored in the normal start storage means. Since the number is larger than the upper limit value, it is possible to reduce the chance that the variable display start condition is invalidated in the variable display device that variably displays the identification information within the limited storage capacity of the storage means.

According to the eighth aspect of the present invention, since the upper limit value changing means for changing the upper limit value of the number stored in the starting storage means in accordance with the satisfaction of the predetermined condition is provided, the satisfaction of the variable display start condition is invalidated. It is possible to further reduce the opportunity to end up.
