Hereinafter, the processing operation of the pachinko machine according to the present embodiment will be described with reference to flowcharts (FIGS. 9 to 19) showing the main parts of the control program stored in the ROM 30. The processing of task 1 shown in FIGS. 9 and 10, the processing of task 2 shown in FIGS. 11 and 13, the processing of task 3 shown in FIGS. 14 and 15, and the processing of task 4 shown in FIGS. The processing is repeatedly executed by the CPU 32 in parallel at predetermined processing cycles (on the order of μs) in accordance with a signal from the clock / reset circuit 36.

The processing of task 1 shown in FIGS.
The CPU 32 sets the value of the random number for the jackpot at every predetermined cycle from 0 to 2
It is generated by sequentially incrementing in the range of 30. Each value of the left, right and middle special symbol data is set based on the value of the random number for the jackpot, and the left, right and middle special symbol data are set by the respective values of the left, right and middle special symbol data. Right, middle and big hit special design data and left,
Create the right and middle special design data, then set the left and right normal design data values based on the value of the big hit random number, and use the left and right normal design data values to set the left and right normal design data. This is to create the data and the normal left and right design data.

The CPU 32 sequentially increments the value of the random number for big hit in the range of 0 to 230 every predetermined processing cycle, and resets the value of the register RAN1 to 0 every time the value of the random number storage register for big hit RAN1 reaches 230. Initialize (step a1 to step a3).

Next, the CPU 32 performs a process for setting each value of each special symbol data and each ordinary symbol data in the second and third bits (values from 0 to 3) of the big hit random number storage register RAN1. 1 is added, and if the added value is 4, it is switched to 0 and stored in the register x. Similarly, the 1st and 2nd bits and the 0th and 1st bits of the big hit random number storage register RAN1 are respectively
If 1 is added and the added value is 4, it is switched to 0 and stored in the registers y and z (step a4), and the registers x and
The values of y and z are respectively stored in the left special symbol data storage register r.
Add to each value of 0 (values from 0 to 14), right special symbol data storage register r1 (values from 0 to 14), and middle special symbol data storage register r2 (values from 0 to 14) Then, the operation result is stored in each of the registers r0 to r2 (step a5).

Then, the CPU 32 determines whether or not the value of each special symbol data storage register r0 to r2 is 15 or more. If the value is 15 or more, the CPU 32 subtracts 15 from the value of the register. The values of the right and middle special symbol data storage registers r0 to r2 are determined (step a6).

As a result, any value from 0 to 14 is set in the left, middle and right special symbol data storage registers r0 and r2. Here, the registers x, y and z are CPU
Reference numeral 32 denotes a register used for internal processing. The values stored in the left, right, and middle special symbol data storage registers r0 to r2 are values of the internal processing index, and are stored in the special symbol data storage registers r0 to r2. The relationship between the value of the internal processing index and the special symbol displayed is as shown in Tables 1 to 3.

[0029]

[Table 1]

[0030]

[Table 2]

[0031]

[Table 3] The CPU 32 has a left, right, and middle symbol data storage register r0.
To r2 are sequentially and individually changed for each processing cycle, thereby creating all the combinations that can be displayed in the symbol, and the combination of the internal processing indices created in the processing cycle is related to the hit symbol. It is discriminated whether the symbol is related to a lost symbol or a lost symbol (steps a7 to a8). If the symbol is a hit symbol, the current values of the internal processing indices r0 to r2 are stored in the left, right, and middle and big hit special symbol data. Stored in each of the registers r0a to r2a (step a
9) If the combination of the internal processing indices created in the processing cycle is related to a lost symbol, the current value of each of the internal processing indices r0 to r2 is changed to the left, right, and centered special symbol data storage registers r0b to r0b. The data is stored in each of r2b (step a10).

Accordingly, in each of the left, right, and middle and big hit special symbol data storage registers r0a to r2a, only the value of the internal processing index related to the hit symbol is sequentially changed and updated and stored. In each of the symbol data storage registers r0b to r2b, only the value of the internal processing index relating to the lost symbol is sequentially changed and stored.

Next, the CPU 32 stores the values of the registers x, y, z determined in the processing of step a4 into the values (0
To 19), left ordinary symbol data storage register r3
(Value from 0 to 3), right normal symbol data storage register r
4 (values from 0 to 3) are added, and the operation result is stored in the respective registers RAN2, r3 to r4 (step a11).

Then, the CPU 32 determines whether the value of the random number storage register RAN2 for normal hit determination is 20 or more. If the value is 20 or more, the CPU 32 subtracts 20 from the value of the register. r4
For, determine whether the value of each register is 4 or more,
If it is 4 or more, 4 is subtracted from the register value to determine the value of the random number storage register RAN2 for normal hit determination and the values of the left and right normal symbol data storage registers r3 to r4 (step a12).

As a result, any value from 0 to 19 is set in the random number storage register RAN2 for normal hit determination, and any value from 0 to 3 is stored in the left and right normal symbol data storage registers r3 and r4. The value is set. here,
The values stored in the left and right ordinary symbol data storage registers r3 to r4 are the values of the internal processing indices, and are the ordinary symbols displayed as the values of the internal processing indices stored in the respective ordinary symbol data storage registers r3 to r4. Are as shown in Tables 4 and 5.

[0036]

[Table 4]

[0037]

[Table 5] The CPU 32 has a left and right ordinary symbol data storage register r0.
To r2 are sequentially and individually changed for each processing cycle, thereby creating all the combinations that can be displayed in the symbol, and the combination of the internal processing indices created in the processing cycle is related to the hit symbol. It is determined whether or not the symbol is related to a lost symbol (step a13). If the symbol is a hit symbol, the current values of the internal processing indices r3 to r4 are left and right, and the normal symbol data storage registers r3a to r3r are used.
4a (step a14). If the combination of the internal processing indices created in the processing cycle is related to a lost symbol, the current value of each of the internal processing indices r3 to r4 is left and right. Symbol data storage register r3
Stored in each of b to r4b (step a15).

The processing of task 2 shown in FIGS. 11 to 13 is for setting the values of each flag and each counter in accordance with the input detection of each of the switches SW1 to SW4.

The CPU 32 has a gate passage detection switch S
It is determined whether or not the detection signal from W1 is input (step b1), and if the signal from switch SW1 is input, it is determined whether or not the value of the normal symbol variation flag fa is not 0 (step b1). b2). The value of the normal symbol variation flag fa is set to 0 in the process of the task 3 while the ordinary symbol display unit 18 is changing or the opening operation of the variable starting port 8 is performed.
Is set, the normal value of fa is 0 when the ordinary symbol display unit 18 can start a new symbol change.
It has become. If the value of the ordinary symbol variation flag fa is 0, the CPU 32 proceeds to step b5, sets 1 to the ordinary symbol variation flag fa, and sets the ordinary symbol display unit 1
The execution of the symbol variation process 8 is permitted, and the process proceeds to step b6.

The value of the gate passage storage number register h is set when the ordinary symbol display flag 18 is a value other than 0 while the ordinary symbol display section 18 is changing, or when the variable starting port 8 is being opened. When the game balls pass through the gates 6, 6, the passage of up to four game balls is stored. C
The PU 32 determines whether or not the value of the gate passage storage number register h is 4 or more (Step b3), and when it is 4 or more, the process proceeds to Step b6. If it is determined in step b3 that the value of the gate passage storage number register h is not equal to or greater than 4, the CPU 32 increments the value of the gate passage storage number register h by one to allow the game ball to pass the current gate. Memorize (step b4), and step b
Move to 6. In the determination process of step b3, when it is determined that the value of the gate passage storage number register h is 4 or more, the passage of the game ball to the gates 6, 6 is not stored.

Whenever the CPU 32 shifts to step b6, the CPU 32 detects the input signal from the first-type start-up winning detection switch SW2 (step b6) and stores the unused random number storage register Ri in the unused fixed random number storage register Ri. The current value is stored (step b7 to step b12). CP
Each time U32 detects an input from any one of the two fixed starting ports 7, 7 and the variable starting port 8, based on the value of the search index i, the storage state identification flag Fi is set to an unused fixed random number storage register. Since Ri is detected, the current value of the big hit random number storage register RAN1 is stored in the determined random number storage register Ri, and the storage state identification flag Fi is set.
As shown in (a), the determined random number storage register Ri stores up to four RAN1 values at the time of winning detection.

Further, the CPU 32 determines whether or not the value of the operation state storage flag Fa is new in order to store the number of times the winning detection has been stored. The value is incremented by one (step b13 to step b14), and the process proceeds to step b15. This is because if the value of the operation state storage flag Fa is new, the special symbol display sections 3, 4, and 5 are in a state where the symbol change processing can be performed, and it is not necessary to display the number of stored symbols on the special symbol storage number display LED15. The value of the winning memory number register N1 is determined by the game to each of the starting ports 7, 8, 7 during the special symbol change based on the winning of the game ball to each of the starting ports 7, 8, 7 and the opening operation of the special winning port 9. It means the memory of the ball winning.

The value of the big hit random number storage register RAN1 changes in a lawful manner every predetermined processing cycle.
Since there is no causal relationship between the winning detection timings for the prizes 8 and 7, and the current value of RAN1, the RA at the time of winning detection is not detected.
The current value of N1 can be used as a random number.

In the case where the input signal from the first-type starting port winning detection switch SW2 is not detected in the discriminating processing in step b6, or when the game ball is won in each starting port 7, 8, 7 in the processing in steps b8 to b10. If up to four have already been stored, the CPU 32 proceeds to step b15
Move to

The CPU 32, which has proceeded to step b15,
It is determined whether or not the signal from the specific area winning detection switch SW3 is input (step b1).
5) If the signal from the specific area winning detection switch SW3 is input, it is determined whether or not the value of the specific area passage detection flag j1 is 0 (step b16). The value of the specific area passage detection flag j1 is set to 1 (step b17), the passage of the game ball to the specific area 13 is stored, and the process proceeds to step b18. The value of the specific area passage detection flag j1 is used to determine whether or not a game ball has entered the specific area 13 during the opening / closing operation of the special winning opening 9; When even a single game ball wins, the value of the specific area passage detection flag j1 becomes 1. If the input signal from the specific area winning detection switch SW3 is not detected in the determination processing in step b15, the CPU 32 proceeds to step b18.

The CPU 32, which has proceeded to step b18,
It is determined whether or not the signal from the special winning opening winning detection switch SW4 is input (step b18). If the signal from the special winning opening winning detection switch SW4 is input, the winning number winning number storage is stored. The value of the counter C4 is incremented by one (step b19), then it is determined whether or not the value of the special winning opening winning number storage counter C4 has reached the predetermined winning number of 10 (step b20). On the other hand, if the value of the special winning opening winning number storage counter C4 has reached the predetermined winning number of 10,
The large winning opening state discrimination flag g2 is set to 2, and the winning of 10 gaming balls is stored (step b21), and the step b
Move to 22. If the signal from the special winning opening winning detection switch SW4 is not input as a result of the determination in step b18, the CPU 32 proceeds to step b22.

The CPU 32, which has executed the input detection processing of the switches SW1 to SW4, proceeds to step b22.
The current value of the winning number register N1 is displayed on the special symbol memory number display LED15, the current value of the gate passing memory number register h is displayed on the gate passing memory number LED 14, and the current value of the special winning opening winning number memory counter C4 is displayed. Is displayed in the special winning opening winning number display, and a special winning opening opening number counter C1 described later is displayed.
Is displayed on the LED for displaying the number of consecutive times, and the process of task 2 is terminated.

The processing of task 3 shown in FIGS.
This relates to the process of changing the normal symbols 10 and 11 and the process of operating the variable starting port 8 which is opened when the symbols of the normal symbols match.

The CPU 32 determines whether or not the current value of the ordinary symbol variation flag fa is 1 (step c1).
If the current value of the ordinary symbol variation flag fa is 0, the CPU
At 32, the process proceeds to a determination process at step c15, but since the determination result is false, the process of task 3 is not substantially performed.

If the current value of the ordinary symbol variation flag fa is 1, a new ordinary symbol variation is executed in the processing of the task 3 (step c2). CPU32
Starts the variation process of the left and right ordinary symbols shown in the timing chart showing the symbol variation process in the left and right ordinary symbol display sections 10 and 11 in FIG. 5. In the same manner as described above, this can be achieved by setting the elapsed time measuring means and the set value which defines the switching time of the fluctuation time and the fluctuation speed of each symbol, and the description on this point will be omitted.

The CPU 32 determines whether or not the left ordinary symbol has been stopped (step c3). If it is determined that the left ordinary symbol has been stopped, the current value of the ordinary symbol state flag f1 is set to 1
Is determined. Since the current value of the ordinary symbol state flag f1 is set to 0 in the initial stage of executing the process of the task 3, the determination result of step c4 becomes false and the process proceeds to step c5. If the left normal symbol is not stopped, the CPU 32 ends the process of the cycle, and changes the left and right normal symbols until the left normal symbol stops in steps c1 to c3 after the next cycle.

The CPU 32 determines whether or not the current value of the probability state setting flag Pr is a value 1 that specifies a high probability (step c5). The value of the probability state setting flag Pr is set on the basis of the result of the specification matching of the special symbols 3, 4, and 5 in the special symbol change and the special winning opening opening / closing operation of the task 4 described later. .

If the value of the probability state setting flag Pr is a value other than 1 in the determination processing of step c5,
The PU 32 determines that the state is the normal probability state. In the case of the normal probability state in which the value of the probability state setting flag Pr is a value other than 1,
The CPU 32 proceeds to step c6 and determines whether or not the current value of the ordinary hit determination random number storage register RAN2 is the set value 19. Since the value of the random number storage register for normal hit determination RAN2 is any one of 0 to 19, in the case of the normal probability, the probability of the set value 19 being hit is 1/20. This probability is lower than the display probability 4/16 obtained by dividing the number 4 of combinations of the symbols having the same left and right ordinary symbols by the total number of combinations 16 of the left and right ordinary symbols.

On the other hand, in the determination process of step c5, if the value of the probability state setting flag Pr is 1 in the high probability state, the CPU 32 proceeds to step c7, where the ordinary hit determination random number storage register is set. It is determined whether or not the current value of RAN2 is in the set value range of 10 to 19 (step c7). When it is determined in the high probability state, the probability that the value 0 of the random number storage register for ordinary collision determination RAN2 is within the set value range is 10/20, that is, 1/20.
2, which is higher than the display probability of 1/4.

If the result of the determination in step c6 or step c7 is true, that is, if it is a hit, the CPU 32 proceeds to step c9, where the left and right hit ordinary symbol data storage registers r3a to r4a store the current values. Left and right stop normal symbol data storage registers r3c to r3
4c (step c9).

If the result of the determination in step c6 or step c7 is false, that is, if the result is a loss, the CPU 32 proceeds to step c9, in which the left and right left normal symbol data storage registers r3b to r4b are stored. The value is stored in each of the left and right stop ordinary symbol data storage registers r3c to r4c (step c8).

After executing the processing of step c8 or step c9, the CPU 32 stores the fact that the reading processing of the value of the random number storage register for normal hit determination RAN2 has been performed by setting 1 to the normal symbol state flag f1. Then, the process proceeds to step c11 to determine whether or not the right normal symbol has stopped (step c1).
1).

If the right ordinary symbol is not stopped,
The CPU 32 terminates the processing of the cycle, executes the processing of steps c1 to c3 after the next cycle, detects the current value 1 of the ordinary symbol state flag f1 in step c4, and proceeds to step c11. Until the normal symbol stops, the right normal symbol fluctuates. In the determination process of step c11, when it is determined that the right normal symbol has stopped, the CPU 32 sets the normal symbol status flag f1 to 0.
Is set and initialized (step c12), and it is determined whether or not the stopped symbol matches with the symbol (step c).
13).

If the left and right ordinary symbols do not match in the discriminating process in step c13, the CPU 32 proceeds to step c19 to store the passing of the game balls to the gates 6 and 6 regarding the next symbol changing process. It is determined whether or not there is.

If the left and right ordinary symbols match in the discriminating process of step c13, the CPU 32 sets the ordinary symbol variation flag fa to 2 and permits the execution of the opening operation process of the variable starting port 8. (Step c14), Step c
In the determination processing of No. 15, since the determination result is true (step c15), the variable starting port opening processing according to the timing chart shown in FIG. 8 is executed until the termination condition is satisfied (step c16 to step c17). Regarding the variable start-up opening process, only the solenoid SOL1 is turned on / off in accordance with the elapsed time measuring means by the same algorithm as the conventional one, and the description is omitted.

When the CPU 32 detects the end condition, the CPU 32 turns off the solenoid SOL1 and closes the variable starting port 8 (step c17 to step c18), and proceeds to step c19 to enter the gate 6 of the game ball relating to the next symbol change processing. 6
Is determined based on whether or not the current value of the gate passage storage number register h is a value other than 0.

If the game ball has passed through the gate, the value of the gate passage storage number register h is one of 1 to 4 by the discrimination processing of step b3 of task 2, and
32, after the discriminating process in step 18, the process proceeds to step c21, in which the value of the gate passage storage number register h is decremented by one (step c21), and the normal symbol variation flag fa
Is set to 1 to permit the next ordinary symbol variation process (step c22), and the process of task 3 is terminated.

In the determination process of step c19, if the determination result is true, that is, if the current value of the gate passage storage number register h is 0 and the passage of the game ball is not stored, the CPU 32 sets the normal symbol variation flag Fa is set to 0 to initialize (step c20), and the process of task 3 ends.

The processing of task 4 shown in FIGS.
It relates to the special symbol fluctuation process and the operation process of the special winning opening 9 which is opened / closed by the symbol matching of the special symbol, and includes a setting probability changing means for setting and changing the symbol matching probability of the ordinary symbol to the high probability and the normal probability. It is a thing.

The CPU 32 determines whether or not the value of the operation state storage flag Fa is 0, that is, whether or not it is in a state where a new symbol can be changed (step d1). If the value of the operation state storage flag Fa is 0, the value is new, and it is not during the process of changing the symbol, during the stop process, during the determination process, or during the opening process of the special winning opening 9, so that the symbol can be changed. Becomes

In this case, the CPU 32 first determines whether or not 1 is set in the storage state identification flag F1.
It is determined whether or not winning in each of the starting ports 7, 8, 7 has already been detected in the processing of the task 2 (step d2).

If a winning in each of the starting openings 7, 8, 7 is detected, the value of the big hit random number storage register RAN1 at the time of winning detection is stored in the determined random number storage register Ri in the processing of the task 2, and The storage state identification flag Fi corresponding to the determined random number storage register Ri is set to 1. At this time, the CPU 32 determines in the order of i = 1 to 4 each time a winning in each of the starting ports 7, 8, 7 is detected. Since the random number is stored in the determined random number storage register Ri, if 1 is set in the storage state identification flag F1, winning at each of the starting ports 7, 8, 7 has been detected at least once. (See step b6 to step b12).

If 1 is set to the storage state identification flag F1, the CPU 32 proceeds to step d3, sets 1 to the operation state storage flag Fa, and stores the start of the variable display (step d3). Processing relating to the fluctuation of each of the left and right symbols is performed (step d4). The processing up to the change and stop of each symbol in the left and right is achieved by setting the elapsed time measuring means and the set value that defines the change time of the change time and the change speed of each symbol as in the conventional case. FIG. 6 is a timing chart showing the symbol change processing in each of the symbol display units 3, 4, and 5. In this embodiment, when the value of the probability state setting flag Pr is a value 1 that defines a high probability, When not high probability, ie 0 or 2
The change time is changed at the time of, but it is detected that the value of the probability state setting flag Pr is 1, and each of the set values C, D, E
Is simply changed to c, d, and e, and a description of this point will be omitted.

As a result of setting 1 to the operation state storage flag Fa, the CPU 32 makes a determination result of false in the determination processing of step d5.
As shown in (b), the data in the storage state identification flags F1 to F4 and the determined random number storage registers R1 to R4 are sequentially shifted to the storage state identification flags F0 to F3 and the determined random number storage registers R0 to R3, and the storage state is determined. 0 is set to the identification flag F4 and the determined random number storage register R4 (step d6).

The CPU 32 operates in a fixed random number storage register R0.
Is equal to the set value 7, that is, the value of the big hit random number storage register RAN1 at the time of winning detection at each of the starting openings 7, 8, 7 which has become a starting stimulus of the present symbol variation processing is a big hit. Is determined (step d7), and if the value of the definite random number storage register R0 matches the set value 7, the process proceeds to step d8.
The values of the right and middle and big hit special symbol data storage registers r0a to r2a are stored in the left, right, middle and display symbol storage registers r0.
c to r2c, while the fixed random number storage register R
If the value of 0 does not coincide with the set value 7, the process proceeds to step d9, where the left, right, and middle special symbol data storage registers r
The values of 0b to r2b are stored in the left, right, and middle display symbol storage registers r0c to r2c, respectively.

The CPU 32 that has executed the processing of step d8 or step d9 sets the operation state flag Fa to 2 and stores the execution of reading the value of the random number storage register for big hit RAN1 (step d10), and proceeds to step d12. I do.

The CPU 32 determines whether or not all the special symbols have been stopped in the determination processing of step 12. When all of the special symbols in the left and right are not stopped, the CPU 32 ends the processing in this cycle, and detects the stop of the special symbol in the next cycle and thereafter. As a result of the operation state storage flag Fa being set to 2, the CPU 32
In the next cycle, after the discriminating processes in steps d1 and d11, the process proceeds to step d4 to continue the special symbol changing process, and then proceeds to step d12 after the discriminating process in step d5.

When all the special symbols in the left and right are stopped, the CPU 32 determines whether or not all three stopped special symbols match (step d13). In the determination processing of step d13, if the stopped special symbols in the left and right do not match, the CPU 3
In step 2, the process proceeds to step d19 to determine whether or not there is a memory for the next special symbol change.

If it is determined in the determination process at step d13 that the three stopped special symbols do not match (step d13), the CPU 32 proceeds to step d13.
The process proceeds to 22 to determine whether or not there is a memory relating to the next execution of the special symbol variation processing by determining whether or not the current value of the winning storage number register N1 is 1 or more.

If the result of the determination in step d22 is true, that is, if there is a memory relating to the next special symbol fluctuation processing, the CPU 32 sets the value of the winning memory number register N1 to 1
Then, it is decremented by one (step d23), the operation state flag Fa is set to 1 and the start of the next special symbol variation process is stored (step d24), and the process proceeds to step d4 to execute a process relating to the variation of the special symbol. .

If the result of the determination in step d22 is false, that is, if there is no storage relating to the next special symbol variation process, the CPU 32 sets 0 to the operation state flag Fa and initializes it (step d25). Then, the process of task 4 is completed.

If it is determined in the determination process at step d13 that all three stopped special symbols match (step d13), the CPU 32 sets 3 to the operation state storage flag Fa and performs special processing. The symbol matching is stored, and the execution of the opening / closing operation processing of the special winning opening 9 is permitted (step d14).

There are 14 combinations of symbols in which all three stopped special symbols are identical. Further, since the value of the random number storage register for jackpot RAN1 changes from 0 to 229, the probability of a jackpot becomes 1/230.

Next, the CPU 32 determines whether or not the current value of the probability state setting flag Pr is 1 in the high probability state (step d15).

As shown in FIG. 4, the value of the probability state setting flag Pr is a normal probability after the power is turned on until the first special symbol matches, and in this case, 0 is set. become. If the determination result of step d15 is false, the CPU 32 proceeds to step d16 and determines whether the combination of the stopped special symbols is 333 or 7 or not.
It is determined whether it is 77 or not (step d16). If the combination of the stopped special symbols is 333 or 777, 2 is set to the probability condition flag g1 (step d17), and the stop is performed. If the combination of special symbols is a jackpot symbol other than 333 or 777, 1 is set to the probability condition flag g1 (step d1).
8), proceed to step d101. In addition, it was stopped
When the combination of special symbols is 333 or 777
Means that the second symbol display means is set in advance.
When the first display mode is performed ”.

Further, in the determination processing of step d15, the current value of the probability state setting flag Pr is set to 1 in the high probability state.
In the case of, the CPU 32 proceeds to step d19, where the stopped special symbols in the left and right are 222, 444 and
It is determined whether it is any one of 666 and 888 (step d19), and if the result of the determination in step d19 is true, the value of the probability state setting flag Pr is switched to 0 to change to the normal probability state ( Step d21), Step d
If the determination result in step 19 is false, the value of the probability state setting flag Pr is switched to 2 to temporarily set the normal probability state (step d20), and the process proceeds to step d18 to set 1 to the probability condition flag g1 (step d18). Step d18), and the process proceeds to step d101. In addition, union of special design which was stopped
Is 222, 444, 666, 888
In this case, the second symbol display means described in claim 1
When the second display mode is set as described above ".

As a result, when the current value of the probability state setting flag Pr is 1 in the high probability state, if the symbol of the special symbol matches, the normal probability becomes 0 or the temporary normal probability 2. Further, the current value of the probability state setting flag Pr is 1 in the high probability state.
Otherwise, 1 or 2 is set in the probability condition flag g1.

The value of the probability state setting flag Pr is changed in the subsequent processing based on the value of the probability condition flag g1. The value of the probability state setting flag Pr is
0 specifies the special symbol loss, 1 specifies the special symbol jackpot, and 2 specifies the special symbol big hit of 333,777.

The CPU 32 that has proceeded to step d101
Executes the special winning opening opening / closing operation processing according to the timing chart shown in FIG.

First, the CPU 32 determines whether or not the opening and closing operation of the new special winning opening 9 can be started, by determining whether or not the value of the special winning opening state determination flag g2 is 0 (step d10).
1). The value of the special winning opening state determination flag g2 is set to 0 in an initial stage, and in this case, a new special winning opening 9 is set.
Can be opened and closed. The CPU 32 sets 1 to the special winning opening state determination flag g2 (step d10).
2), the start of the opening and closing operation of the special winning opening 9 is stored, the set value A is set to the parameter X (step d103), and the timer T1 is operated to start measuring the elapsed time (step d104). It is determined whether or not T1 has reached the set time X (step d105).

If the elapsed time T1 has not reached the set time X in the determination processing of step d105, the CPU 3
2 ends the processing of this cycle. In the processing of task 4 after the next cycle, the operation state storage flag F
As a result of the setting of 3 in a, the CPU 32 determines that the current value 3 of the operating state storage flag Fa is detected in the determination process of step d11 after the determination process of step d1, and the process proceeds to step d101. In the determination process, it is determined to be false, the process proceeds to step d106, and the value 1 of the special winning opening state determination flag g2 is detected, and the process proceeds to step d10.
Move to 5.

In the determination process of step d105, when it is detected that the elapsed time T1 has reached the set time X,
The CPU 32 sets and switches the value of the special winning opening state determination flag g2 to 3 (step d107), sets the set value t1 to the parameter X (step d108), starts the timer T1, and starts measuring the elapsed time. Then, the excitation command is output to the solenoid SOL2 to open the special winning opening 9 (step d110), and the value of the special winning opening release counter C1 is incremented by one (step d111).

Next, the CPU 32 determines whether or not the value of the special winning opening state determination flag g2 is 2, that is, whether or not ten gaming balls have won the special winning opening 9 (step d112). . If ten gaming balls have been awarded in the special winning opening 9, the value of the special winning opening state determination flag g2 has been switched to 2 in the processing of steps b20 to b21 of the task 2. In this case, the CPU 32 determines in step d112
Is true, the winning number winning counter winning number counter C4 is initialized (step d124), and the routine proceeds to step d114.

If the determination result of step d112 is false, the CPU 32 determines whether or not the elapsed time T1 has reached the set time X (step d113), and the elapsed time T1 has reached the set time X. If not, the processing in this cycle ends. In the processing of the task 4 after the next cycle, the current value of the operation state storage flag Fa is 3, and the step d1
As a result of the fact that the special winning opening state determination flag ga is set to 3 at 07, the CPU 32 determines that after the determination processing of step d1,
Since the current value 3 of the operation state storage flag Fa is detected in the determination process of step d11, the process proceeds to step d101. In the determination process of step d101, the determination is false, and the process proceeds to step d106. Since the result is false, the process proceeds to step d112.

If it is determined that the elapsed time T1 has reached the set time X in the determination processing of step d113, the CPU
32 initializes the special winning opening winning number counter C4 (step d124), outputs an excitation release command for the solenoid SOL2, and closes the special winning opening 9 (step d11).
4) The value of the special winning opening counter C1 is a predetermined number 1
6 is determined (step d115). If the predetermined number 16 has not been reached, it is determined whether the specific area passage detection flag j1 is 1 (step d116).
If the specific area passage detection flag j1 is 1, the specific area passage detection flag j1 is set to 0 and initialized (step d117), the parameter X is set to the set value B (step d118), and the special winning opening state determination The flag g2 is set to 1 to permit the continuous opening operation of the special winning opening 9 to be continued (step d119), and the process proceeds to step d104.

In this way, when the opening and closing operation of the special winning opening 9 is continued and the number of opening and closing reaches the predetermined number of 16 times, the present value 16 of the special winning opening opening number counter C1 is detected in the determination processing of step d115. Then, the CPU 32 proceeds to step d120. Alternatively, if the total number of the game balls that have won the special winning opening 9 reaches 10 without any of the game balls winning in the specific area 13 during the opening of the special winning opening 9 once, the CPU 32 executes the task. After the determination process in step b16 of step 2, the value of the specific area passage detection flag j1 remains 0, so that the determination process in step d116 is determined to be false, and the process proceeds to step d120. In the latter case,
Even if the number of opening of the special winning opening 9 does not reach 16, the continuous opening and closing operation of the special winning opening is stopped.

The processing from step d120 to step d123 changes the value of the probability state setting flag Pr based on the value of the probability condition flag g1.

CPU 32 having proceeded to step d120
Determines whether the current value of the probability state setting flag Pr is 2 (step d120). As shown in FIG. 4, when the determination result of step d120 is true, that is, when the probability before the symbol matching of the current special symbol is high is high, the probability state setting is performed by the symbol matching of the current special symbol. In the case where the value of the flag Pr is changed to the temporary normal probability state of 2, the symbol combination of the special symbol which has started the opening and closing operation of the special winning opening 9 this time is 222, 444, 6
Jackpot symbols other than 66,888, for example, 111, $
If it is $, the CPU 32 sets 1 to the value of the probability state setting flag Pr (step d12).
2), the state is switched from the temporary normal probability state to the high probability state, and the probability condition flag g1 is set to 0 for initialization (step d123).

If the current value of the probability state setting flag Pr is 2 in step d120, the current value of the probability state setting flag Pr is set to 1 in the processing of step d122. The value of the probability state setting flag Pr in the case where the determination result is false is 0 which specifies the normal probability and not 2 which specifies the temporary normal probability.

As described above, step d101
Thereafter, in the processing up to step d122, the current value of the probability state setting flag Pr is not in the high probability state 1.

Therefore, if the result of the determination at step d120 is false, that is, if the value of the probability state flag Pr is not the temporary normal probability 2, the value of the probability state flag Pr is the normal probability 0. Is to determine whether or not the current value of the probability condition flag g1 is 2 (step d121). In the determination process of step d121, if the current value of the probability condition flag g1 is 2, the symbol set of the special symbol which has become the starting stimulus of the opening / closing operation of the current special winning opening 9 by the processes of steps d15 to d17. Since the match was a big hit symbol of 333,777, the CPU 32 sets the value of the probability state setting flag Pr to 1 (step d122), switches from the normal probability state to the high probability state, and sets the probability condition flag. g
Initialize by setting 0 to 1 (step d123).

If the decision result in the step d120 is false,
That is, this is the case where the value of the probability state flag Pr is the normal probability 0, and if the current value of the probability condition flag g1 is not 2 in the discrimination processing of the step d121, the step d
After the determination process of step 15 and step d16, the process proceeds to step d18, and the probability condition flag g1 is set to 1, or after the determination process of step d15 and step d19, the process proceeds to step d21 and step d18 to set the probability state This is either the case where the value of the setting flag Pr is returned from the high probability state to the normal probability state and the probability condition flag g1 is set to 1.

If the value of the probability state flag Pr is normal probability 0 and the current value of the probability condition flag g1 is not 2 in the determination processing of step d121, the CPU 32
The probability condition flag g1 is set to 0 and initialized (step d123). In this case, the value of the probability state flag Pr generally remains at 0.

The value of the probability condition flag g1 is determined at step d17 or step d18 by the symbol matching of the special symbol.
Is set to a value other than 0 in any one of the processes, and is set to 0 in the process of step d123 by the end of the continuous opening and closing operation of the special winning opening 9.

CPU that has executed the process of step d123
32 initializes the special winning opening counter C1 (step d125), and proceeds to step d22 to determine whether or not there is a memory relating to the execution of the next special symbol fluctuation processing, by checking the current value of the winning memory number register N1. The determination is made by determining whether or not the number is 1 or more, but the description is omitted because it has been described above.

When the value of the probability state setting flag Pr is 1 in the high probability state by the processing of the task 4, the special symbol display sections 3, 4, 5 in the left and right sides of the game board 1 are displayed.
Is switched from red to green, and the left and right ordinary symbol display sections 10, 1 are displayed to the player.
Recognize that the probability that the symbol 1 matches increases.

The progress of the game on the game board 1 of the pachinko machine of the embodiment will be briefly described according to the winning state of the game balls. When the game balls pass through the gates 6 and 6, the normal symbol display sections 10 and 11 are displayed. It fluctuates, and the normal symbol display part 1 in the order of left and right
0, 11 are stopped. Left and right ordinary symbol display parts 10 and 11
When the display result of the first specific condition, that is, both the left and right symbols are the same symbol, the variable starting port 8 is opened.

When the game ball wins in the opened variable starting port 8 or fixed starting port 7, 7, the special symbol display portions 3, 4, 5 in the left and right are changed, and the special symbols are displayed in the order of the left and right. Stopped. Each stop symbol in the left and right is the second specific condition,
That is, when all three stopped special symbols have the same symbol, the special winning opening 9 is opened for a predetermined time, but even if the game balls are won 10 times even within the predetermined time, the special winning opening 9 is closed. You. This is referred to as one opening / closing operation of the special winning opening 9.

At this time, in the internal processing by the CPU 32,
The value of the probability condition flag g1 is a value other than 0 to 0, that is, 1
Or it is switched to 2. That is, when the three stopped special symbols satisfy the preset condition, that is, when the three stopped special symbols are any of 333,777, the probability condition flag g1 is set. Is set to 2, and if the three special symbols stopped are other than 333,777, the value of the probability condition flag g1 is set to 1, and in this case, the three special symbols stopped at the same time Is 2
If it is any of 22, 444, 666, 888, the probability state setting flag Pr is set to a value 0 defining the normal probability state, and the three special symbols stopped are 222, 444, 66.
If the value of the probability state setting flag Pr before stopping the three special symbols is a value 1 that specifies the high probability state, the probability state setting flag P
The value of r is temporarily switched to a value 2 that defines the normal state. Here, the value of the probability state setting flag Pr specifies the probability that the symbol display sections 10 and 11 are stopped with the same symbol on the left and right symbols. The three special symbols stopped are 22
If it is not any of 2,444,666,888,
The second symbol display means according to claim 2 is set in advance.
Any of the third display mode and the first display mode.
When it becomes. "

When the game ball passes through the specific area 13 in the special winning opening 9 opened by matching all the special symbols, after the closing of the special winning opening 9, the opening and closing operation of the special winning opening 9 is performed again. During one opening / closing operation of the special winning opening 9, the game ball is moved to the specific region
Is performed once, the opening and closing operation of the special winning opening 9 is repeatedly performed. If this is referred to as the continuous opening and closing operation of the special winning opening 9, the continuous opening and closing operation of the special winning opening 9 can be performed up to 16 times including the first time.

At the time when the continuous opening and closing operation of the special winning opening 9 ends, the internal processing by the CPU 32 determines whether the value of the probability condition flag g1 is 2 or the value of the probability state setting flag Pr is temporarily normal. If the value is 2 that defines the state, the value of the probability state setting flag Pr is returned to the value 1 that defines the high probability state.

As a result, when the display result of the special symbol display sections 3, 4, 5 is 333,777, after the continuous opening / closing operation of the special winning opening 9, the normal symbol display section 10, The probability that the left and right normal symbols of 11 coincide with each other becomes a high probability, and the possibility of causing the special symbol display portions 3, 4, and 5 to change the special symbol increases. Normal symbol display part 10,
The condition that the probability that the left and right ordinary symbols of 11 coincide with each other is high is that the special symbol display units 3, 4, and 5 display 222,
444, 666, or 888,
When the display result of the special symbol display sections 3, 4, 5 is any of these four combinations, the ordinary symbol display sections 10, 11
The condition that matches with a high probability of disappears and is returned to the normal probability.
