Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reads a numerical value used for a predetermined judgment in a game from a predetermined storage area in a game control program, updates the read numerical value for judgment, and updates the judged numerical value for the predetermined value. The present invention relates to a gaming machine that performs a random number update process stored in the storage area.

2. Description of the Related Art A game machine has a game control program including a first program forming a main routine that is normally executed and a second program forming an interrupt routine executed by an interrupt instruction. ing. In addition, a game machine is widely known in which various determinations in a game (for example, big hit lottery, symbol determination, variation pattern determination, etc.) are performed using random numbers.

The random number used for the determination is a random number updating process of reading a numerical value used for a predetermined determination in a game from a predetermined storage area, updating the read numerical value, and storing the updated numerical value in the predetermined storage area. , A numerical value is read from the predetermined storage area according to a predetermined game situation (for example, in response to detection of winning at a starting opening), and the read numerical value is used as a random number (determination numerical value).

Conventionally, in each of the first program forming the main routine and the second program forming the interrupt routine executed by the interrupt instruction, the same kind of judgment numerical value is used for the predetermined judgment in the game. There is a game machine that performs a random number update process for a determination numerical value (random number).

FIG. 7 is a flow chart showing the structure of a game control program in the above-mentioned conventional gaming machine.
FIG. 8 is a flowchart showing a subroutine of random number updating processing in the game control program of FIG. In such a conventional gaming machine, in the random number updating process of the specific random number (for example, the random number for jackpot determination) of the first program, the determination numerical value (updated) stored in a predetermined storage area is updated. Before reading the previous determination numerical value, updating the read determination numerical value (+1 in this example), and saving (storing in the predetermined storage area) the updated determination numerical value (+1 determination numerical value) There is a case where an interrupt instruction is entered in (see FIG. 8), and when an interrupt instruction is entered, processing is performed as described below.

That is, first, the random number updating process of the specific random number is interrupted, and then the second program (interrupt routine of FIG. 7) as the interrupt process is started. Then, in the random number updating process of the same specific random number (random number for jackpot determination in this example) in the second program, the determination numerical value (determination numerical value before update) stored in the predetermined storage area is again used. The read numerical value for determination is updated (+1 in this example), and the updated numerical value for determination (+1 numerical value for determination) is saved (stored in a predetermined storage area). Then, after the completion of the second program which is the interrupt process, the process is returned to the random number updating process of the specific random number in the first program, but here, the process after the interrupt command is entered is continued. Will be done.

In the above example, as a result, the random number updating process of the specific random numbers of the same type is performed twice. However, even though the random number update process of the specific random number is performed twice, in the first program, the same pre-update determination numerical value (same value) is updated and saved. The phenomenon that the saved numerical value for determination is updated only once (only the updated storage made by the first program) occurs. Such a phenomenon is suspected that the random number is not updated accurately, leading to lack of reliability as a gaming machine.

[0008]

To control the payout of prize balls. Further, the firing control circuit 17 controls driving / stopping of the hitting ball launching device, and based on a stop command / stop cancellation command from the game control device 1, drives the ball hitting launching device 18 to stop / drive.

Next, a game control program provided in the game control device 1 of the pachinko gaming machine of the embodiment will be described. FIG. 2 is a flowchart showing the configuration of the game control program stored in the ROM of the game control device 1 for the pachinko gaming machine of the embodiment.

As shown in FIG. 2, the game control program normally includes a first program forming a main routine executed by the main CPU and an interrupt routine executed by the main CPU in response to an interrupt instruction. And a second program to be formed. The main routine is a process for setting the stack pointer (step S01), and a process for determining whether or not the power is turned on (step S0).
2), initialization processing that is executed only when the power is turned on (step S03), interrupt prohibition processing (step S04) that is executed regardless of whether the power is turned on, and execution is performed subsequent to the interrupt prohibition processing of step S04. Random number update process (step S
05), the interrupt permission process (step S06) performed after the random number update process of step S05.

Further, the interrupt routine performs a saving process for saving the value of the register used in the main routine to the stack area (step S11), monitoring the shortage of prize balls, and controlling the number of prize balls paid out. Prize ball control processing (step S1
2), random number update processing (step S13), normal symbol starting sensor 5 and starting switch detection processing (step S14) for reading various random numbers related to winning detection by the starting mouth sensors 4a, 4b, ordinary symbol of the ordinary symbol display device 15 Ordinary symbol-related processing (step S1) relating to hit determination, variation and stop of ordinary symbols, and control processing of ordinary electric auditors
5), big hit determination regarding the special symbol, special symbol relation processing regarding the fluctuation and stop of the special symbol and opening control of the special winning opening (step S16), the starting winning prize stored due to the starting winning of the ordinary symbol and the special symbol It is composed of a lamp control process (step S17) relating to lighting control of the number of holdings, other processes (step S18), and a return process (step S19) for returning the value saved in the stack area to the register.

In the embodiment shown in FIG. 2, step S0 provided in the main routine (first program).
The random number updating process of 5 and the random number updating process of step S13 provided in the interrupt routine (second program) are the same process.

The main CPU sets the stack pointer when the power is turned on (step S01), then determines whether the power is turned on or not (step S02), and is executed only when the power is turned on. Initialization processing is performed (step S03), and when the initialization is completed, the process proceeds to step S04. In the initial setting process of step S03, the interrupt timing (2 ms in this embodiment) stored in the ROM of the game control device 1 is read and C
Set the register in the PU to set the interrupt timing. Also set the start time of the interrupt time. That is, from the time of this setting, the internal timer of the one-chip microcomputer 2 operates to measure the time and generate an interrupt command at every interrupt timing (2 ms).

At step S04, the main CPU
Performs interrupt prohibition processing (step S04), and subsequently executes random number update processing (step S05). Therefore, during execution of the random number updating process of step S05, even if an interrupt instruction comes in, it is ignored, that is, the second instruction by the interrupt instruction.
The execution of the program (interrupt routine) is prohibited. When the main CPU finishes the random number updating process in step S05, it performs an interrupt permission process (step S06).
Therefore, the interrupt permission process enables the interrupt command,
When an interrupt instruction comes in, the second program (interrupt routine) is started.

When the main CPU starts the interrupt routine, it saves the value of the register used in the main routine in the stack area (step S11), and step S1.
Each processing of 2 to step S18 is sequentially executed (the random number updating processing of step S13 is also naturally executed), and when the value saved in the stack area is returned to the register (step S19), the processing returns to the main routine.

When the main CPU returns to the main routine, the remaining time until the next interrupt instruction is input, step S0.
4, the processing loop formed in step S05 and step S06 is repeatedly executed. Therefore, the random number updating process of step S05 is repeatedly executed a plurality of times.

As described above, with respect to the random number updating process (step S05) of the first program provided in common to the first program (main routine) and the second program (interrupt routine). Since the interrupt prohibition process is provided immediately before the start of the random number update process and the interrupt permission process is provided immediately after the end of the random number update process, during execution of the random number update process of the first program, Since the start of execution of the two programs is prohibited, it is possible to accurately update the determination numerical value used as a random number for the predetermined determination in the game.

Further, in the case of the embodiment shown in FIG. 2, as shown in FIG. 3, the time required from the interrupt prohibition process to the interrupt permission process is approximately 0.01 at the current processing speed of the CPU.
It is 5 ms (= 15 μs). On the other hand, the time required to execute the interrupt routine changes depending on the game situation. For example, in the prize ball control processing, the processing time differs (changes) depending on whether there is a prize ball or not. Also,
In the start switch detection process, the processing time differs depending on whether there is a start detection or not. Further, in the normal symbol-related processing, time is changed when a normal symbol is detected or a variation command of the normal symbol is performed. Furthermore, in the special symbol-related processing, the display control circuit 1 issues an instruction to start changing the special symbol.
The processing time differs depending on whether the instruction is given to No. 3 or not. In the lamp control process, the processing time differs depending on whether the lighting instruction is issued or not.

In the case of the present embodiment, the time required to execute the interrupt routine is about 1.7 ms at the minimum and about 1.9 ms at the maximum at the current processing speed of the CPU. According to this, the remaining time until the next interrupt instruction (every 2 ms) is input is about 0.3 ms (= 300 μ).
s) to 0.1 ms (= 100 μs). Therefore, in this embodiment, the number of times that the random number updating process of step S05 is repeatedly performed is 300/15 to 100/15, which is within a range of approximately 6 to 20 times. In this way, the random number updating process of the first program (step S
The number of executions of 05) changes depending on the game situation. Therefore, the updating degree of the judgment numerical value used as a random number for the judgment of the game changes according to the game situation (if the number of times of repetition this time is 6, the judgment numerical value is updated as much as 6 times, If the number of repetitions of is 15 times, the determination numerical value is updated as much as 15 times), and thus the determination numerical value itself can be treated as a random number.

Next, various random numbers used in the pachinko gaming machine of the embodiment will be described. The RAM of the game control device 1 is provided with various random number counters (storage areas) for updating and storing values used as various random numbers. In this embodiment, as various random number counters, a normal symbol random number counter RAN1 and a big hit determination random number counter R

In addition, the random number value acquired in response to the winning detection by the starting opening sensor 4a or 4b is 17
Alternatively, if the number is 31, it is treated as a winning, and the reach is lost.

Each time it is read, it is incremented by 1 and is cyclically updated in the range of 0 to 11. In addition, at the time of determination of the jackpot design,
For example, when the value of the random number counter RAN6 for jackpot design determination is "0", the jackpot design is "000".
In addition to this, an initial value random number for determining an initial value at the start of updating the random number of the big hit determination random number RAN2 may be appropriately provided.

Next, the value of the register is updated by +1 (step A02), and it is determined whether the updated value of the register is out of the range (10 or more in this embodiment) (step A03) and updated. If the register value is out of the range, 0 is set in the register and the process proceeds to step A05 (step A04). If the updated register value is not out of the range, the process directly proceeds to step A0.

Then, the value of the register is updated by +1 (step A18), and it is determined whether the updated value of the register is out of the range (12 or more in the present embodiment) (step A19) and updated. If the register value is out of the range, 0 is set in the register and the process proceeds to step A21 (step A20). If the updated register value is not out of the range, the process directly proceeds to step A21. When the main CPU proceeds to step A21, it stores the updated register value in the right special symbol random number counter RAN3b (step A21).

That is, the main CPU reads the value of the fluctuation pattern determining random number counter RAN5 set as a predetermined storage area of the RAM into the register (step A33). Then, the value of the register is updated by +1 (step A34), and the updated value of the register is out of the range (50 in this embodiment).
The above is determined (step A35), and if the updated value of the register is out of the range, 0 is set in the register and the process proceeds to step A37 (step A36), while the update is updated. If the register value is not outside the range, the process directly proceeds to step A37. Main CPU

Interrupt prohibition that prohibits the execution start of the second program by an interrupt instruction from before being read from the time until the updated determination numerical value is stored in a predetermined storage area And management, after storing the determination numerical value updated in a predetermined storage area, may be a structure in which the interrupt permission process for permitting execution start of the second program by interrupt instruction.

The same type of judgment numerical value (random number) is also used in the second program if the random number (judgment numerical value) whose random number is updated in the first program is a big hit judgment random number. It means a configuration in which the big hit determination random number is updated.

FIG. 6 is a flow chart showing the second embodiment of the configuration of the game control program stored in the ROM of the game control device 1. The second program (interrupt routine) of the second embodiment is the same as that of the embodiment shown in FIG. Further, the first program (main routine) of the second embodiment is different only in the process related to the update of random numbers, and the other processes are the same as those in the embodiment shown in FIG. That is, in the second embodiment shown in FIG. 6, in the first program (main routine), the random number updating process for the big hit determination random number (steps A06 and A0 shown in FIG. 4).
7, Step A08, Step A09 and Step A1
0)), and the second program (interrupt routine) performs the random number updating process (random number updating process for all random numbers) shown in FIGS. 4 to 5.

In this case, the second program commonly includes a random number updating process for the big hit determination random number provided in the first program. In addition, in regard to the random number update processing for the big hit determination random numbers of the first program that is provided in common, at least a numerical value is read out from the big hit determination random number counter (predetermined storage area), and interrupt prohibition processing is performed. It is sufficient to prohibit the execution start of the second program by the interrupt instruction from the time when the numerical value is read from the big hit determination random number counter until the updated value is stored in the big hit determination counter. After the numerical value is stored in the jackpot determination random number counter (in a predetermined storage area), an interrupt permission process for permitting the execution start of the second program by the interrupt instruction may be provided (see FIG. 6).

In the above-mentioned embodiment, the method of updating the random number is +1 with respect to the numerical value for judgment.
Not limited to this, the determination numerical value to be updated and added can be appropriately determined. Alternatively, a method of subtracting a certain value from the upper limit value may be used. For example, a method of subtracting −1 from the upper limit value may be used. In this case, when the updated value becomes 0, the upper limit value may be rewritten.

Further, the random number updating process of the first program and the random number updating process of the second program are performed at least by the same updating method, but not limited to this, for example,
The random number update process performed by the first program is an update that increments the determination numerical value by 1, and the random number update process that is performed by the second program is an update that increments the determination numerical value by +3. The second program may have a different updating method, and the first program and the second program may include random number updating processing for the same type of determination numerical value (random number).

Further, in the above-described embodiment, the random number of the game control device 1 is used. However, for example, the random number update process provided in the display control circuit 13, the lamp control circuit 10 or the voice control circuit 11 is applied. The invention may be applied.

[0052]

According to the configuration of the first aspect, during execution of the random number update process provided in the first program forming the main routine, at least before reading the determination numerical value from the predetermined storage area, Until the updated determination numerical value is stored in the predetermined storage area, the execution start of the second program forming the interrupt routine by the interrupt instruction is prohibited, so the random number update provided in the first program is updated. In the process, since the determination numerical value used as the random number for the predetermined determination in the game is accurately updated, the suspicion about the random number can be dispelled and the reliability as the gaming machine can be maintained.

According to the configuration of claim 2, the random number updating process provided in the first program and the random number updating process provided in the second program can be made into one subroutine process, so that the program is slim. Can be converted.

According to the configuration described in claim 3, the number of executions of the random number updating process of the first program provided in common to the first program and the second program changes according to the game situation. Therefore, the updated numerical value itself can be treated as a random number.
