Abstract

PROBLEM TO BE SOLVED: To provide a Pachinko (Japanese pinball game) machine capable of making the prediction of the transition of a large prize numerical value from the external of a main control part impossible and preventing the foul play using 'suspended substrate' in advance by generating the large prize at random in a figure display unit without changing a large prize numerical value setting means for setting the large prize numerical value. SOLUTION: In a play, whether the possibility of new start of a figure variation exists or not is judged when a figure varying process is started in a CPU 25, a large prize numerical value stored in a large prize numerical value storing resistor is stored in a present time large prize numerical value memory when the judgement is YES, and the numerical values stored in the other large prize numerical value storing resistors are successively shifted. When the large prize numerical value is agreed with one of plural large prize judgement values in a case of high probability with the setting of a probability varying flag, the result of the present figure variation is judged to be a large prize. By switching the large prize judgement value at random correspondingly to the game state, the foul play by 'suspended substrate' can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention includes a symbol display device for displaying a jackpot loss, and compares a jackpot numerical value randomly selected for use in setting a jackpot related to the symbol display device with a jackpot determination value. More particularly, the present invention relates to a pachinko gaming machine that determines a big hit when it matches, and determines that it comes off when it does not match, and particularly to a pachinko gaming machine that randomizes the timing of occurrence of a big hit in a symbol display device.

[0002]

2. Description of the Related Art A pachinko game machine equipped with a symbol display device for displaying a big hit or a miss is widely known. In such a pachinko gaming machine, a big hit numerical value used to set a big hit related to the symbol display device is set.

[0003] The big hit value starts from 0 when the power is turned on, and is periodically updated by one within a preset range of 0 to N at predetermined intervals. For example, starting from 0 at power-on, every time a reset interrupt signal is input (for example, every 2.000 ms), it is incremented by 1 and is initialized to 0 when it reaches 359. As a result, it circulates from 0 to 358. . Therefore, in this case, one cycle of the big hit value is (2.000 × 359 =) 718.
000 ms. The normal probability of a big hit in the game is 1
In the case of / 359, the big hit value for generating a big hit is determined when a predetermined specific value (for example, 5) from 0 to 359 is taken. The big hit determination is made by comparing the big hit numerical value with the big hit determination value (5 in the above case). If they match, the big hit is determined.

Therefore, in the above case, the value for the big hit is 2.000 × 5 = 10000 ms after the power is turned on.
Later, one predetermined specific value (for example, 5) that causes a big hit is taken, and thereafter (718.0) every predetermined period.
(Every 00 ms)
Two specific values (for example, 5) will be taken.

[0005] The timing for selecting the jackpot numerical value is determined when a winning of a pachinko ball is detected in a starting port provided in the game board (when a detection signal of a starting winning detection switch provided in the starting port is present). Therefore, the big hit value at the time of performing the lottery according to the detection signal of the start winning detection switch is:
When the value is one predetermined value (for example, 5), a big hit occurs.

In the prior art, since the timing of winning the pachinko ball into the starting opening is random, the randomness of the value of the jackpot that is randomly selected based on the winning of the pachinko ball into the starting opening is also guaranteed. I was Therefore, the jackpot numerical value drawn based on the winning of the pachinko ball to the starting port could be used as the jackpot determination random number.

[0007] However, recently, unauthorized alterations, which are so-called "hanging boards", in which unauthorized components are attached between the main control board and peripheral devices, have been significantly increased.
This is to take in the signal periodically output from the main control board, etc. to constantly monitor the big hit value, and to illegally delay the output timing of the detection signal when the game ball passes the start winning switch. This is a fraudulent act of intentionally generating a big hit by sending a detection signal to the main control unit at a timing when the big hit value becomes a big hit.

[0008] Since the fraudulent act using the "hanging board" does not involve any modification to the main control unit itself of the pachinko game machine, only measures for preventing fraudulent acts such as replacement with a fraudulent ROM or a fraudulent CPU are provided. Cannot be prevented, and security cannot be said to be maintained.

[0009] Since the fraudulent act due to the "hanging board" is a method of remodeling around the starting winning switch wiring, a certain degree of operation is also performed by the game arcade side, such as strengthening the surveillance in the game arcade, periodic visual inspection, and the like. Although it seems possible to prevent this, it is an urgent task to take technical measures to further improve the security of the gaming machine itself.

[0010] Since the fraudulent act by the "hanging board" is a fraudulent act caused by the current random number updating, lottery, and judgment methods, it is theoretically difficult to modify the method by changing a part or all of these methods. Is very effective as a countermeasure.

[0011]

The game contents of the pachinko gaming machine of the embodiment will be schematically described. When the game ball passes through one of the left and right gates 3 and 4, the symbol on the symbol display 9 usually starts changing, and stops changing after about 5.0 seconds.
Note that there are ten types of symbols commonly used for symbols, from “0” to “9”. When the normal symbol whose fluctuation is stopped is “1,” “3,” “5,” “7,” or “9,” the normal electric accessory 5 is activated, and the starting winning opening 8 is the symbol of the special symbol display device 7. When the jackpot lottery probability related to the fluctuation is the normal probability, the opening is expanded for about 0.3 seconds, and when the jackpot lottery probability is the high probability, it is opened for about 4.5 seconds. When three pachinko balls are awarded to the opening winning opening 8 during opening, the opening operation of the opening opening opening 8 ends even within the opening time.

When the pachinko ball wins the starting winning opening 8,
The special symbol of the special symbol display device 7 starts to change in the order of the left symbol, the right symbol, and the middle symbol. When about 7.7 seconds or more elapse after the start of the symbol change, the symbols are stopped in the order of the left symbol, the right symbol, and the middle symbol, and the special symbol is determined. However, when the lottery probability of the big hit related to the symbol change of the special symbol display device 7 is a high probability, the change time is shortened, and when about 5.2 seconds or more elapse after the symbol change starts, the left symbol, the right symbol The symbols are stopped in the order of the symbol and the middle symbol, and the symbol is determined.

"444,""555,""666,""7777,"
In the case of “gold, silver and gold”, “gold, gold and gold”, “sakura cherry blossoms”, “ball A ball B ball A”, and “ball A ball A ball A”, a big hit is established.

That is, the condition device operates, the special winning opening solenoid SOL2 operates, the opening and closing door 16 rotates forward, and the special winning opening 17 is opened for a predetermined time (29.0 seconds). . As in the conventional case, up to four winning memories in the starting winning opening 8 are stored. In the case other than the combination described above, the condition is removed and the condition device does not operate.

If ten game balls are won during opening of the special winning opening 17, the special winning opening 17 is closed with the tenth winning. If the game ball passes through the specific area 18 during the opening of the special winning opening 17 and within about 1.5 seconds from the time when the special winning opening 17 is closed, the accessory continuous operation device (establishment of continuous operation) is activated. Then, after the opening of the special winning opening 17 being opened, the special winning opening 17 is repeatedly opened again. The opening operation of the special winning opening 17 is a maximum of 16 times including the first opening operation.

The special symbol combinations that have achieved the jackpot are the specific symbols “333”, “555”,
In the case of “Seven-Seven-Seven”, “Kinkin-Gin”, “Sakura-zakura-zakura”, or “Tama-A-Tama-A-TamaA”, a special symbol display device 7 is provided from the stop of the operation of the condition device to the start of the operation of the next condition device. , The lottery probability of the big hit related to the symbol change shifts to the high probability (6/359). When the condition device operates again with the above-mentioned specific symbol during the high probability, the operation of the condition device is stopped, and then a new high probability is set. When the condition device operates four times in succession with the above-mentioned specific symbol, the condition device operates with a normal symbol other than the above-mentioned specific symbol at the next operation of the condition device. The lottery probability of the big hit related to the symbol change of the special symbol display device 7,
Shift to normal probability (1/359).

Next, a means for randomly selecting a big hit value and a big hit value to be used for setting a big hit related to the special symbol display device 7 of the present invention, and a means for randomly selecting a big hit value to be used for setting the big hit. Means for determining a big hit when the values match and determining a big hit if they do not match, and a random number for determining the big hit according to a change in the game state during the game. A means for randomizing the timing of occurrence of a big hit in the special symbol display device 7 by means of a big hit determination value switching means for switching the hits will be described.

Although not shown as a flowchart,
The CPU 25 shown in FIG. 2 performs initialization processing when power is turned on, and performs various registers, various flags,
Initialize various counters and various storage areas. In the initialization process, the initial value of the jackpot numerical value NUBA used for setting the jackpot related to the special symbol display device 7 is set to 0.

At the time of the jackpot determination, each of the initial values of the jackpot determination values AHT1 to AHT6 to be compared with the random number selected at random is a jackpot determination value AHT1.
Is "7", the jackpot determination value AHT2 is "71", the jackpot determination value AHT3 is "107", the jackpot determination value AHT4 is "173", the jackpot determination value AHT5 is "227", and the jackpot determination value AHT6 is "307". Set.

Further, the big hit determination values AHT1 to AHT
No. 6 for switching, which is updated to switch No. 6
To HTN6 are set to the same values as the initial values of the big hit determination values AHT1 to AHT6. That is, the switching determination value HTN1 is “7”, the switching determination value HTN2 is “71”,
Switching decision value HTN3 is "107", switching decision value HT
N4 is "173" and the switching determination value HTN5 is "22".
7 ", the switching determination value HTN6 is set to" 307 ". The reason why the initial values of the switching determination values HTN1 to HTN6 are set as described above is to set the switching determination values HTN1 to HTN6 to take different values from each other.

When the lottery probability regarding the big hit is a low probability (1/359), 1 of the big hit determination value AHT1 is set.
Only one is used for the jackpot determination and is compared with a random number selected for the jackpot. If the lottery probability regarding the big hit is a high probability (6/359), the big hit determination value A
All six of HT1 to AHT6 are used in the jackpot determination, and these are compared with random numbers selected for the jackpot.

FIG. 3 to FIG. 10 show a change of the game control program stored in the ROM 26 for the change of the big hit value related to the symbol change of the special symbol display device 7 and the big hit determination values AHT1 to AHT6. Judgment value H
It is a flowchart which shows the part of update processing of TN1-HTN6 in outline.

The clock reset circuit 28 shown in FIG.
A reset signal is sent to the CPU 25 every 2.000 ms. When a reset signal is input to the CPU 25, the CP
U25 interrupts the main routine of the game control process including the symbol variation process related to the special symbol display device 7, for example,
The process proceeds to the numerical value update process shown in the flowchart of FIG.

When starting the numerical value updating process, the CPU 25 increases the value of the big hit numerical value NUBA by one (step A01), and determines whether or not the updated big hit numerical value NUBA has reached 359 (step A01). Step A0
2). The initial value of the big hit value immediately after turning on the power is
It is set to 0 by the initialization processing.

When the value of the big hit numerical value NUBA has reached 359, the CPU 25 sets the big hit numerical value NUBA to 0 and proceeds to step A04 (step A0).
3) If the value of the big hit number NUBA has not reached 359, the process directly proceeds to step A04.

As described above, the value of the big hit value NUBA starts from the initial value 0 when the power is turned on, and is set to 0 to 0 every predetermined period (every time a reset signal is input at a period of 2.000 ms). 1 within a preset range of 358
It is updated cyclically one by one.

The CPU 25 that has proceeded to step A04
The numerical values of the switching determination values HTN1 to HTN6 are updated. That is, after setting 1 to the index register i (step A04), the CPU 25 proceeds to step A05 to increase the numerical value of the switching determination value HTN (i) by one (step A05), and updates the switched determination. Value HTN
It is determined whether or not the value of (i) has reached 359 (step A06). If the value of the switching determination value HTN (i) has reached 359, the switching determination value HTN (i) is set to 0 ( Step A07), while the process proceeds to step A08,
If the value of the switching determination value HTN (i) has not reached 359, the flow directly proceeds to step A08. The CPU 25 determines whether or not the index register i has reached 6 (step A).
08) If the index register i has not reached 6, the index register i is updated by one (step A09), and thereafter, the processing loop of steps A05 to A09 is repeated, and each of the switching determination values HTN1 to HTN6 is Increase the numerical value by one and update.

As a result, the value of the switching determination value HTN1 becomes
Starting from the initial value 7 from power-on, every time a reset signal is input at a period of 2.000 ms, 0 to 35
8 are updated one by one within a preset range.

The value of the switching determination value HTN2 starts from an initial value 71 from the time of power-on, and changes from 0 to 358 every time a reset signal is input at a period of 2.000 ms.
Are updated cyclically one by one within a preset range of.

The value of the switching determination value HTN3 starts from the initial value 107 when the power is turned on, and the reset signal is 2.
Every time it is input at a period of 000 ms, it is cyclically updated one by one within a preset range of 0 to 358.

The value of the switching determination value HTN4 starts from an initial value 173 when the power is turned on, and when the reset signal is 2.
Every time it is input at a period of 000 ms, it is cyclically updated one by one within a preset range of 0 to 358.

The value of the switching determination value HTN5 starts from an initial value 227 when the power is turned on, and the reset signal is 2.
Every time it is input at a period of 000 ms, it is cyclically updated one by one within a preset range of 0 to 358.

The value of the switching determination value HTN6 starts from an initial value 307 when the power is turned on, and when the reset signal is 2.
Every time it is input at a period of 000 ms, it is cyclically updated one by one within a preset range of 0 to 358. When the index register i reaches 6, the CPU 25 returns to the main routine.

As described above, the switching decision values HTN1 to HTN1 to HTN
When the update of TN6 is completed, the switching determination value HTN1
To HTN 6 are different from each other.

FIG. 4 is a flow chart showing a process related to winning detection of the starting opening winning detection switch SW1, which is a part of the switch process executed by the CPU 25.

The CPU 25 has a start opening winning detection switch S
Each time the winning detection signal from W1 is inputted, the big hit numerical value N is stored in the unused big hit numerical storage register RAN (i).
The current value of UBA is stored (step B01 to step B05). The CPU 25 searches the storage state identification flag F (i) based on the value of the index register i (step B02 to step B03) each time a winning in the start winning opening 8 is detected (step B01). Flag F
If (i) is not stored (value is 0), the current value of the big hit numerical value NUBA is stored in the big hit numerical storage register RAN (i) (step B04), and the storage state identification flag F
(I) is set to be stored (value is 1) (step B0)
5).

If the storage state identification flag F (i) is not stored (the value is 0), the value of the index register i is updated by one and the next storage state identification flag F (i) is searched (step S1). B06, step B07), it is determined whether or not the storage state identification flag F (i) indicates that there is no storage (step B03). When all of the jackpot numerical value storage registers RAN1 to RAN4 have already stored the jackpot numerical value NUBA, even if the value of the index register i is updated to 4, the storage state identification flags F (i) are all stored. Therefore, after determining that the storage state identification flag F (4) has been stored,
The index register i is updated and the index register i is updated.
Reaches 5, and the result of the determination in step B07 becomes true. As a result, the current value of the big hit numerical value NUBA is not stored. As a result, up to four values of the big hit numerical value NUBA are stored.

Here, since the timing of winning the pachinko ball into the starting winning opening 8 is random, the value of the numerical value NUBA for the jackpot that is randomly selected based on the detection of the winning of the pachinko ball into the starting winning opening 8 is determined. Randomness is also guaranteed.

Therefore, the jackpot numerical value storage register RAN1 storing the jackpot numerical value NUBA randomly selected.
RAN4 can also be used as the jackpot determination random numbers.

FIGS. 5 and 6 are flowcharts showing the outline of the symbol change process of the special symbol display device 7 executed by the CPU 25, and show a process related to a big hit determination which is a part of the process. When starting the symbol variation process, the CPU 25 first determines whether or not a new symbol variation can be started (step C01). In addition, when the symbol has already been changed (during the change of the symbol or during the display of the stopped symbol that has been fixed) and during the big hit operation (during the operation of the condition device), it is impossible to start a new symbol change.

When a new symbol change can be started, the CPU 25 sets the big hit numerical value storage register RA as described above.
The big hit numerical value NUBA stored in N1 is stored in the big hit numerical storage register RAN0 this time (step C
02), big hit value storage registers RAN2 to RAN
4 is sequentially shifted to the big hit value storage registers RAN1 to RAN3 (step C03), the contents of the big hit value storage register RAN4 are cleared, and the big hit value storage register RAN is cleared.
Then, the storage state determination flag F (4) corresponding to No. 4 is cleared to 0, and the big hit value can be stored in the big hit value storage register RAN4 (step C04).

Next, it is determined whether the result of the symbol change performed this time is a big hit or a miss (step C05).
The CPU 25 determines the set state of the probability variation flag,
High probability that the probability variation flag is set (6/35
In the case of 9), this time the big hit numerical value storage register RAN
Big hit numerical value NUBA stored in 0 and big hit determination value A
HT1 to AHT6 are sequentially compared with each other, and the big hit value NUBA is changed to the big hit determination values AHT1 to AHT6.
Is determined to be a big hit, while the big hit numerical value NUBA is equal to the big hit determination values AHT1 to AHT.
If it does not match any of the numbers 6, it is determined that it is off (step C07).

If the probability change flag is cleared and the probability is low (1/359), the big hit value NUBA stored in the current big hit value storage register RAN0 is compared with the big hit determination value AHT1, and the big hit is determined. Numerical value for NUB
If A matches the jackpot determination value AHT1, it is determined that a jackpot has occurred, while the jackpot numerical value NUBA is determined to be the jackpot determination value AH.
If it does not match T1, it is determined that the connection has been lost (step C0).
6).

When a big hit is determined, the big hit flag is set (step C08), and when it is determined that the big hit is found, the big hit flag is cleared (step C09).

Next, the CPU 25 sequentially sets various conditions required for symbol fluctuation (steps C10 to C10).
Step C11). In addition, about the setting of various conditions required for a symbol change, detailed description will be omitted and will be briefly described.

First, a left symbol, a right symbol and a middle symbol to be finally stopped are determined (step C10). If it is determined to be a big hit, it is determined to be one of the combinations of the big hit symbols, and if it is determined to be out, it is determined to be one of the combinations of the missing symbols.

When it is determined that the big hit is determined, the type of the reach operation is determined so that the big hit symbol determined in the above processing is finally stopped and displayed. Decide whether or not to reach during a change, and if you want to do reach (in this case,
Although the reach operation is performed but eventually comes off, it is referred to as "miss reach"), and the type of the reach operation is determined so that the off design determined in the above process is finally stopped and displayed. Depending on whether the reach operation is performed or not, one of the later-described symbol variation patterns is determined.

Also, it is determined whether or not a big hit notice is given during the symbol change. Further, it is determined whether or not the re-change operation of the left symbol, the right symbol and the middle symbol is performed during the symbol variation (step C11).

After these various conditions are set, the change of the left symbol, the right symbol and the middle symbol is started (step C1).
2) After the variation pattern described later, the left symbol, the right symbol, and the middle symbol are stopped and displayed and fixed (step C1).
3). When the left symbol, the right symbol and the middle symbol are stopped and displayed, the big hit flag is determined (step C14), and the condition device is operated only when the big hit flag is set (step C15). Also, when the condition device is activated,
The opening number counter C1 for counting the number of opening of the special winning opening 17 is cleared to 0 (step C16), and the processing shifts to the big hit processing. In the case of a departure, the current drawing variation process ends.

FIGS. 7 to 9 are flowcharts of the big hit process executed by the CPU 25. Also, FIG.
It is a flowchart which shows the subroutine of the big hit determination value switching process which PU25 performs.

In the following description, an embodiment according to the requirements of claim 2 will be described. That is, an embodiment will be described in which the switching process for randomly switching the big hit determination value is performed according to the detection of the pachinko ball that has won the big winning opening 17.

The big hit process is a process executed only when it is determined that a big hit is made in the symbol variation process and the condition device is activated. When the big hit process is started, the CPU 25 first determines whether or not the condition device is operating (step S01). If the condition device is not operating, the result of the determination in step S01 becomes false, so that no substantial jackpot processing is performed.

When the condition device is operating, the big hit processing is executed. After the determination in step S01, the CPU 25
Stops the operation of the continuous actor (step S0).
2) The opening time of the special winning opening 17 (29.00 seconds) is set in a timer (step S03), and a winning number counter C for counting the number of pachinko balls won in the special winning opening 17 is set.
2 is set to 0, the value of the open counter C1 is increased by one (step S04), and the special winning opening solenoid SOL2 is set.
Then, the special winning opening 17 is opened by outputting the drive excitation signal to the step (S05), and the process proceeds to the step S06.
Thus, the first opening operation of the special winning opening 17 is started.

The CPU 25 that has proceeded to step S06,
It is determined whether or not a pachinko ball has won the special winning opening 17. That is, it is determined whether or not there is a winning detection signal from the special winning opening winning detection switch SW3 (step S0).
6). The CPU 25 includes a special winning opening winning detection switch SW3.
When the winning detection signal from the player is input, the value of the winning number counter C2 is incremented by one (step S07), and in response to the detection of the pachinko ball winning the big winning opening 17, the step S is performed.
08 big hit determination value switching processing is performed.

CPU 2 having shifted to the big hit determination value switching process
5 switches each value of the big hit determination values AHT1 to AHT6 to each current value of the switching determination values HTN1 to HTN6 (step S100). The CPU 25 proceeds to step S10
After the processing of 0, the process returns to the jackpot processing, and step S09
Move to

The timing of winning the pachinko ball into the special winning opening 17 and the switching determination values HTN1 to HTN described above.
6 does not have any causal relationship with the current values of the large hits, it is not possible to switch the values of the big hit determination values AHT1 to AHT6 to the current values of the switching determination values HTN1 to HTN6 at the time of winning detection. Switching is performed in a random manner.

On the other hand, if there is no input of the winning detection signal from the special winning opening winning detection switch SW3 in step S06, the CPU 25 directly proceeds to step S09.

In step S09, it is determined whether or not the pachinko ball has won a specific area 18 provided inside the special winning opening 17 (step S09). That is, CP
U25 determines whether or not there is a winning detection signal from the specific area passage detection switch SW4, and when the winning detection signal is input from the specific area passage detection switch SW4,
The continuous action device for actors is operated (step S10), and the process shifts to the timer process of step S11. If no winning detection signal is input from the specific area passage detection switch SW4, the process directly shifts to the timer process of step S11.

Note that in the timer processing of step S11,
The timer value that sets the opening time of the special winning opening 17 is subtracted.

After the processing in step S11, the CPU 25
The special winning opening 17 is determined in steps S12 to S13
It is determined whether or not the closing condition is satisfied. That is, in step S12, it is determined whether or not the number of pachinko balls that have won the open special winning opening 17 has reached 10 (step S12). If the current value of the winning number counter C2 for counting the number of pachinko balls that have won the special winning opening 17 has reached 10, the CPU 25 proceeds to step S1.
Then, the special winning opening 17 is closed by turning off the drive excitation signal of the special winning opening solenoid SOL2 (step S14). As described above, even when the special winning opening 17 is open, when the number of the pachinko balls that have won the special winning opening 17 reaches ten, the special winning opening 17 is closed.

In step S12, if the number of the pachinko balls that have won the open special winning opening 17 has not reached ten, the CPU 25 proceeds to step S13. In step S13, it is determined whether the opening time of the special winning opening 17 has ended (step S13). CPU2
In step 5, when the opening time of the special winning opening 17 is completed, the process proceeds to step S14, in which the output of the drive excitation signal of the special winning opening solenoid SOL2 is turned off to close the special winning opening 17 (step S14).

If the number of pachinko balls that have won the special winning opening 17 has not reached 10, and the opening of the special winning opening 17 is in progress, steps S12 and S
13 are false, the CPU 25 determines in step S0
6, and thereafter, the processing loop formed by steps S06 to S13 is repeated until one of the determination results in step S12 and step S13 becomes true.

Now, in step S14, the special winning opening 17
Is closed, the CPU 25 determines whether or not the condition for terminating the big hit processing is satisfied by the processing of step S15 and subsequent steps.

In step S15, the special winning opening 17
It is determined whether or not the number of times of opening has reached 16. CPU
25, when the number of times the special winning opening 17 has been opened reaches 16, the operation of the accessory continuous operation device is ended (step S2).
2), the operation of the condition device is terminated (step S23), and the big hit processing is terminated. As a result of the termination of the operation of the condition device, the big hit processing is not performed after the next cycle.

If the CPU 25 determines in the determination processing in step S15 that the number of times of opening of the special winning opening 17 has not reached 16, the valid time (about 1.5 seconds from the closing of the special winning opening 17). Is set in the timer (step S1).
6) The process proceeds to step S17.

At step S17, it is determined whether or not the accessory continuous operation device is operating (step S1).
7). During the opening of the special winning opening 17 this time, if a pachinko ball has won a specific area 18 provided inside the special winning opening 17, as a result of the processing of step S <b> 09 and step S <b> 10, The continuous actuator is operating. If the continuous actuating device is in operation (note that
The condition device remains in operation), the CPU 25 starts the jackpot process from the start, and the closed special winning opening 17 is opened again (transfer to the next round).

In step S17, when it is determined that the accessory continuous operation device is not operating, the detection of the winning of the pachinko ball to the specific area 18 is enabled for about 1.5 seconds from the closing of the special winning opening 17. The process proceeds to CPU25
Determines that the step S17 is false, and then determines whether or not there is a winning detection signal from the specific area passage detection switch SW4 (step S18).

In step S18, when a winning detection signal is input from the specific area passage detection switch SW4, the CPU 25 operates the accessory continuous operation device (step S21), and then the condition device remains operating. As a result, the jackpot process is started from the start, and the closed special winning opening 17 is opened again (transfer to the next round).

In step S18, if there is no input of the winning detection signal from the specific area passage detection switch SW4, the CPU 25 shifts to the timer processing of step S19, and subtracts the timer value for which the valid time has been set. It is determined whether the valid time has expired (step S2).
0).

Thereafter, the CPU 25 repeats steps S18 to S20 until the valid time ends, and determines whether or not there is a winning detection signal from the specific area passage detection switch SW4. If there is no input of the winning detection signal from the specific area passage detection switch SW4, the CPU 25 determines that step S20 is true, and then proceeds to step S23 to end the operation of the condition device.
The jackpot process ends. As a result of the termination of the operation of the condition device, the big hit processing is not performed after the next cycle.

As described above, if the pachinko ball does not win in the specific area 18 provided inside the grand prize opening 17 while the grand prize opening 17 is being opened, the closed grand prize is closed. The mouth 17 does not open again, and the big hit operation ends.

FIG. 11 shows a special winning opening 17 at the time of a big hit.
Timing of Pachinko Ball Winning and Big Hit Judgment Value AHT
4 is a timing chart showing a relationship with a switching timing of No. 1; As shown in FIG. 11, when a big hit occurs in the special symbol display device 17, the condition device is activated, and the special winning opening 17 is opened. The value of the jackpot determination value AHT1 at the time of opening the special winning opening 17 is A1, which is one of the ranges from 0 to 358. When a pachinko ball wins in the open special winning opening 17, it is detected by the special winning opening winning detection switch SW3. The value of the jackpot determination value AHT1 is switched in response to the winning detection of the first pachinko ball, and the value of the jackpot determination value AHT1 is switched from A1 to the current value A2 of the switching determination value HTN1 at this time. .

Thereafter, when the second pachinko ball wins in the open large winning opening 17, the value of the big hit determination value AHT1 is switched again according to the detection of the winning of the second pachinko ball, Again, the value of the big hit determination value AHT1 is switched from A2 to the current value A3 of the switching determination value HTN1 at this time. FIG. 11 shows a case where ten pachinko balls are won in the open special winning opening 17 during opening, and the value of the big hit determination value AHT1 is switched ten times in response to the ten winning detection operations. Shows that the value of the big hit determination value AHT1 has been switched to A11.

Since there is no causal relationship between the timing of winning the pachinko ball into the special winning opening 17 and the current value of the switching determination value HTN1, the value of the big hit determination value AHT1 is determined at the time of winning detection. By switching to the current value of the switching determination value HTN1, the value of the big hit determination value AHT1 is randomly switched.

Therefore, the jackpot determination value is randomly switched, so that the timing of the jackpot occurrence in the special symbol display device 17 is randomized without changing the means for setting the jackpot numerical value for setting the jackpot numerical value NUBA. As a result, it is possible to make the transition of the numerical value for the jackpot unpredictable from outside the main control unit, and it is possible to realize protection against fraud using the “hanging board”.

As described above, the requirement according to claim 2, that is, the switching processing for randomly switching the jackpot determination value is performed in the big winning opening 1
7 has been described (performed in response to the winning detection signal of the special winning opening winning switch SW3), the switching timing (the switching is performed) of randomly switching the big hit determination value. Opportunity to do)
Not only the switching timing of the above-described embodiment but also various switching timings are possible within the scope of the gist of the present invention.

The jackpot determination value switching process is not performed in accordance with the winning detection signal of the special winning opening winning switch SW3, that is, the jackpot determination value switching process is not performed after step S07 shown in FIG. For example, FIGS. 7 and 8
As indicated by a chain line, a configuration may be such that a jackpot determination value switching process is performed following the process of step S10 and a jackpot determination value switching process is performed following the process of step S21.
This configuration corresponds to the requirement described in claim 3,
The switching processing of the jackpot determination value is performed in a random manner in accordance with the detection of the pachinko ball that has won the specific area 18 provided inside the special winning opening 17.

Further, the big hit determination value switching processing is not performed in accordance with the winning detection signal of the big winning opening winning detection switch SW3. For example, as shown by a chain line in FIG.
It is good also as a structure which performs a big hit determination value switching process following the process of 05. This configuration corresponds to the requirement described in claim 6, and the switching process of the jackpot determination value is performed by the special winning opening 17.
Are switched in a random manner in accordance with the output operation of the drive signal for opening operation.

Further, the jackpot determination value switching process is not performed in accordance with the winning detection signal of the jackpot detection switch SW3. For example, as shown by a chain line in FIG. The determination value switching process may be performed. This configuration corresponds to the requirement described in claim 5, and the means for switching the big hit determination value is used to detect a pachinko ball that has won the starting winning opening 8 for starting symbol fluctuation in the special symbol display device 7. Switching is performed in a random manner in response to the request.

Next, the display operation of the special symbol display device 7 will be described. FIG. 25 is a timing chart showing the processing timing of the CPU 25 relating to the special symbol display device 7. When a reset signal from the clock reset circuit 28 is input to the CPU 25, the CPU 25 performs an interrupt process. After input processing for various switches,
Starting opening winning detection switch SW in the switch determination process
When an input of 1 is detected, in the interrupt processing,
The above-mentioned big hit numerical value NUBA is stored in the RAM 27. Then, it is determined whether or not the big hit value stored in the RAM 27 matches a predetermined big hit determination value. It should be noted that when the big hit value stored in the RAM 27 matches the big hit determination value, a big hit occurs, and when the big hit numerical value stored in the RAM 27 does not match the big hit determination value, the game goes out.

In the present embodiment, the change of the jackpot probability is switched, and the medium probability (1/359)
In the case of, if the big hit value stored in the RAM 27 is the big hit determination value AHT1 and the probability is high (6/359), the RAM
If the big hit numerical value stored in 27 is any one of AHT1 to AHT6, it is a big hit. The change of the change of the jackpot probability with the low probability and the high probability will be described later.

The types of the left symbol, the right symbol, and the middle symbol that are finally determined and stopped are determined. When the above determination result is out of order, the types of the left symbol, the right symbol, and the middle symbol that are finally fixed and stopped are determined by the outlying symbol setting table on the basis of the read out symbol value for the off symbol. When the above determination result is a big hit, the types of the left symbol, the right symbol, and the middle symbol that are finally fixed and stopped are determined by the big hit symbol setting table based on the read big hit symbol values.

Next, whether or not a reach operation is to be performed is determined by the reach operation setting table in accordance with the read reach operation numerical value, regardless of whether or not a big hit has occurred.
In the case of a big hit, a reach operation is always performed. Further, in the case of the departure, there is a case where the reach operation is not performed and a case where the reach operation is performed. The type of the reach operation will be described later.

Further, regardless of whether the result of the big hit determination is a big hit or not, it is determined whether or not to make a big hit notice. The determination method and type of the jackpot notice will be described later.

Further, a reach operation described later is a big hit in a normal symbol other than the reach operations D5, D6, M0 and M1, or a reach operation D5, D6, M0 and M
If it is other than 1 and it is a big hit in the specific symbol shown in FIG. 24 and the read value of the re-variation operation numerical value is an odd number, it is determined to perform the re-variation operation.

Then, conditions for starting the special symbol change are set, and the change of the special symbol is started. In the latter half of the special symbol fluctuation time, a rewriting process to the stopped symbol determined by the stopped symbol determining process is performed. In addition, a special symbol change suspension time is provided after the left symbol, the right symbol, and the middle symbol are fixed and stopped.

FIG. 26 is a timing chart schematically showing the symbol changing operation of the left symbol display section 12, right symbol display section 13 and middle symbol display section 14 of the special symbol display device 7.

When the pachinko ball wins the starting winning opening 8 and a winning is detected by the starting opening winning detection switch SW1 (at the time of activation), the left symbol of the special symbol display device 7 becomes 0.
After 002 seconds, the right symbol starts changing after 0.226 seconds, and the middle symbol starts changing after 0.450 seconds. The time required from the start of the change of each symbol to the time of symbol determination is the time of T1 for the left symbol,
The right symbol is the time of T2, the middle symbol is the time of T3, and the display time T4 after the symbol is determined is 1.6 when the probability is low.
The display time T4 is 56 seconds and the display time T4 is 0.600 seconds in the case of a high probability of failure, and the display time T4 is longer than 1.656 seconds when there is no prize memory in the starting winning opening 8 and when there is a big hit.
After the start of the change of the symbols, the symbols are stopped in the order of the left symbol, the right symbol, and the middle symbol, and the symbol is fixed.

FIG. 27 is a timing chart showing the time required from the start of the first change in the number of stored special symbols to the final determination of the fourth symbol when the combination of missing symbols is continuous. . The maximum value of the time required from the start of the change in the number of stored special symbols to the determination of the symbol by the fourth symbol is a low-probability swaying motion, and a -1 symbol of a reach motion D5 described later. Change in outlier by 4
It is the maximum when it is performed consecutively.

There are three types of movements of the left symbol, the right symbol, and the symbol of the middle symbol, that is, a scroll motion, a swing motion (sliding motion), and a temporary stop motion (re-fluctuation motion). The scroll fluctuation indicates a fluctuation state in which the symbols smoothly change in a predetermined direction at a predetermined fluctuation speed in a predetermined symbol arrangement state, and there are eleven types of scroll fluctuations A to K. FIG. 28 shows the contents. FIG. 29 shows a visual recognition state of each scroll change.

The swinging operation (sliding operation) indicates a state in which the symbol swings up and down.
There are two types of swing operation A and swing operation B due to the difference in speed, the contents of which are shown in FIG. 30 and FIG. 31 shows the visual recognition of the swing operation.

Further, the pause operation (re-fluctuation operation)
FIG. 32 shows an operation state in which the changing symbol is temporarily stopped and then starts to change again. FIG. 32 shows a visual recognition state of the temporary stop operation.

The time required from the start of the change of the special symbol to the decision of the symbol has a fluctuation range. The condition for changing the fluctuation time is that the lottery probability of the big hit related to the symbol change of the special symbol display device 7 is the normal probability. (Hereinafter referred to as a low probability) to a transition to a high probability and a transition to a high probability to a low probability. (A state in which a big hit may be established depending on the stop symbol of the symbol).

The special symbol fluctuation operation includes a case where a reach operation is performed and a case where it is not performed. The reach operation is performed in a total of 32 types (for convenience, A0 to A2, B0 to B2) depending on the type of the character displayed on the picture display unit 15 and the difference in the story developed by the operation of the character.

As described above, when the result of the jackpot determination is a jackpot with a low probability, the lottery is performed for each of the jackpot notice A, the jackpot notice B, the jackpot notice C, the jackpot notice D, and the jackpot notice E. , The probability of winning each of the notices is 38/253, 54/253, 26/253, 41
/ 253 and 8/253.

The determination of winning by lottery at the time of the low probability at the time of the big hit is made by the reach numerical value (in the range of 0 to 252, which is cyclically updated or updated in the range of 0 to 252) when the winning detection of the starting opening winning detection switch SW1 is detected. Is determined based on the low-probability middle and big hit notice selection table in FIG. 72.

If the result of the jackpot determination is a jackpot at the time of high probability, a lottery is performed for each of the jackpot notice A, the jackpot notice B, the jackpot notice C, and the jackpot notice E, and the winning probability of performing each notice is determined. But 38/253, 75 /
253, 26/253, and 6/253.

The winning determination by lottery in the case of a high probability and a big hit is determined by the reach numerical value (cyclically updated or updated in the range of 0 to 252) read at the time of winning detection of the starting opening winning detection switch SW1. It is determined based on the high-probability middle and big hit notice selection table in FIG.

If the result of the jackpot determination is out of range and no reach operation occurs, the jackpot notice A
Is drawn only for, and the winning probability is 6/25
3 is set.

It is assumed that the result of the big hit determination is out of range and a reach operation occurs. This condition is defined as out-of-reach occurrence. If the outreach occurs,
When the medium symbol stops one symbol before the big hit symbol at the low probability, lottery is performed for the big hit notice A, the big hit notice B, and the big hit notice D, and the winning probability of performing each notice is 64/253, 15 /. 253 and 30/253.

Also, in the case where the out-of-reach reach occurs and the middle symbol stops one symbol after the large hit symbol at a low probability, the lottery is performed for the large jackpot notice A, the large jackpot notice B, and the large jackpot notice D, respectively. The probability of winning each of the notices is 59/253, 22/253, 36/253
Is set to

Further, in the case where the out-of-reach reach occurs, and at a low probability, when the middle symbol stops in a symbol other than one symbol before the large hit symbol and one symbol after the large hit symbol, only the large hit notice A A lottery is performed, and the winning probability is set to 95/253.

[0200] In the case where the out-of-reach reach occurs and the middle symbol stops one symbol before the big hit symbol at a high probability, the lottery is performed only with respect to the big hit notice A, and the winning probability becomes 73/253. Is set.

In the case where the out-of-reach reach occurs and the middle symbol stops one symbol after the large hit symbol at a high probability, the jackpot announcement A, the jackpot announcement B, and the jackpot announcement C
, A lottery is performed, and the winning probabilities of performing the respective announcements are set to 64/253, 38/253, and 6/253.

In the case where the out-of-reach reach occurs, at a high probability, when the middle symbol is stopped in a symbol other than one symbol before the big hit symbol and one symbol after the big hit symbol, the lottery is performed only with respect to the big hit notice A. The winning probability is 73/2
53 is set.

[0203] Note that the start of the jackpot notice is set by storing 1 in bits 0 to 2 of the reach flag when the result of the jackpot determination is out of order and the reach operation is not performed. Set the start.

When the result of the big hit determination is a big hit, and when the reach operation is performed even if the result of the big hit determination is out of place, the flag setting corresponding to the type of the big hit notice to be started in FIG. 74 is made. As shown, bits 0 to 2 of the reach flag and bit 7 of the special symbol flag
A value corresponding to the type of the big hit notice to be started is set.

Next, the low probability of the jackpot probability (1/359)
The high probability (6/359) changeover process will be described. FIG. 75 is a timing chart showing the timing of the change processing of the big hit probability by the CPU 25. At power-on, the jackpot probability is set to a low probability. According to the jackpot determination, when the condition device is activated by a jackpot due to a combination of symbols other than the specific symbol shown in FIG. 24 (ordinary jackpot symbol), the probability variation flag is cleared and switched to a low probability, and the number of times of the probability variation is repeated. Clear the counter.

When the condition device is activated by the big hit determination and the big hit by the combination of the specific symbols shown in FIG. 24, the probability fluctuation flag is cleared and switched to the low probability, and the value of the probability fluctuation continuous number counter is increased by one. .

When the condition device operates with the specific symbol,
At the end of the operation of the condition device, it is determined whether or not the value of the continuous probability variation counter is 0. If the value of the continuous probability variation counter is not 0, the probability variation flag is set and the high probability variation flag is set. Switch to. When the value of the probability variation continuous number counter is 0, the value of the probability variation flag does not change, so that the value remains 0 and the probability is low.

When the condition device is activated by a big hit, the probability fluctuation flag is cleared and switching to the low probability is performed. Therefore, during the period of high probability, the next time from the end of the operation of the condition device, Until the start of operation of the condition device.

FIG. 76 is a timing chart showing switching of the change of the jackpot probability when the condition device is operated four times in succession in a specific symbol. In the present embodiment, the number of consecutive times when the condition device continuously operates in a specific symbol is limited to four times. That is, when the condition device is operated with a specific symbol four times in a row, after the end of the operation of the fourth condition device, at the time of the fifth big hit, a symbol other than the specific symbol (a normal big hit symbol) becomes a big hit, and the conditional device is operated. Is working.

In FIG. 76, when the power is turned on, the probability variation flag (KAKFG) is cleared, and the big hit probability is set to a low probability. In addition, the value of the probability variation continuous number counter (KAKCT) is also set to 0.

When the condition device is activated by a big hit (first time) due to a specific symbol, the probability variation flag is cleared and switched to low probability, and the value of the probability variation continuous number counter is incremented by one. When the operation of the condition device is completed, the value of the probability variation continuous number counter is 1, so that the probability variation flag is set and the probability is switched to the high probability.

Thereafter, when the condition device is activated again by a big hit (second time) due to the specific symbol, the probability variation flag is cleared and switched to a low probability, and the value of the probability variation continuous number counter is increased by one. When the operation of the condition device is completed, the value of the probability variation continuous number counter is 2, so that the probability variation flag is set to switch to the high probability.

In this manner, the condition device is activated by a big hit by a specific symbol four times in succession, and when the condition device is finished operating, the value of the probability fluctuation continuous number counter is 4, and the probability Set the fluctuation flag and switch to high probability.

Thereafter, when it is determined that the big hit is a big hit, the value of the probability variation continuous number counter is determined to be 4, and the special symbol normal big hit table (FIG. 24) is set so that the specific symbol does not appear at the time of the big hit. A table for selecting a normal jackpot symbol other than the specific symbol shown) and the random number for the jackpot symbol are selected and set.

[0215] As a result, the condition apparatus is activated by a big hit with a normal big hit symbol, the probability change flag is cleared, the probability change flag is switched to a low probability, and the probability change continuous number counter is cleared. And, at the time when the condition device is completed,
As a result of the value of the probability variation continuous number counter being 0, there is no change in the value of the probability variation flag, so that the value remains 0 and the probability is low. Note that the reach operation in the specific symbol is not performed from the end of the fourth operation to the start of the fifth operation of the condition device.

[0216]

According to the pachinko gaming machine of the present invention, the jackpot determination value switching means compares the jackpot determination value randomly selected with a jackpot numerical value to be used for setting the jackpot related to the symbol display device. Is randomly switched in accordance with a change in the game state during the game, so that the timing of occurrence of the big hit in the symbol display device is randomized without changing the means for setting the big hit value for setting the big hit value. As a result, it is possible to make the transition of the numerical value for the jackpot unpredictable from outside the main control unit, and it is possible to realize protection against fraud using the “hanging board”.
