The respective values of the reach determination counter LC6 and the reach pattern determination counter LC7 are sequentially stored in the storage areas 1 to 4 of the special symbol random number storage area 52b, and the corresponding LED of the special symbol start holding unit 25 is turned on. Therefore, the maximum number of reservations is four.

When the ordinary symbol operation switch 73 provided at each of the ordinary symbol starting gates 11 and 12 detects the passage of the game ball, the ordinary symbol stored in the loop counter storage area 52a of the RAM 52 is provided. The value of the selection loop counter LC1 is stored in the normal symbol random number storage area 52.
The memory is sequentially stored in the storage areas 1 to 4 of c, and the corresponding LED of the ordinary symbol start holding unit 26 is turned on. Therefore, the maximum number of reservations is four.

When the switch reading process (S8) is completed,
Next, a loop counter updating process (S9) is performed. In the loop counter updating process (S9), the normal symbol selection loop counter LC1, the big hit determination loop counter LC2, and the special symbol creation counters LC3 and L3 stored in the loop counter storage area 52a of the RAM 52, respectively.
The values of C4, LC5, reach determination counter LC6, and reach pattern determination counter LC7 are increased (incremented) by the above-mentioned predetermined amount. When the value exceeds the maximum value set in each loop counter, the value of each loop counter is cleared to 0 and programmed to return to "0".

Next, in the main routine of the pachinko machine 1 shown in FIG. 10, when the loop counter updating process S9 ends, it is determined whether or not an error has occurred in the pachinko machine 1 (S10). If an error has occurred (S10: YES), the condition device processing (S1)
1), special symbol processing (S12), ordinary symbol processing (S1)
3) is skipped to perform the processing, and the special symbol display device 8 displays an error or the like. If no error has occurred (S10: NO), the process proceeds to the condition device process (S11).

Next, in the condition device processing (S11), opening and closing of the special winning opening 16 and a big hit demonstration display process on the special symbol display device 8 are performed. In the first round of processing, since the jackpot determination processing in the special symbol processing (S12) described later has not been performed yet, the condition device processing (S1)
In 1), nothing is performed and the process proceeds to the next process. Next, a special symbol processing (S12) is performed.

In the special symbol processing (S12), a big hit determination processing, which will be described later, is performed. When the special symbol processing (S12) is completed, next, the normal symbol processing (S1)
3) is performed. In the ordinary symbol processing (S13), the passing of the game ball to the ordinary symbol starting gates 11 and 12 causes
Normally, the count value of the symbol selection loop counter LC1 is
Since the normal symbol random number is stored in the ordinary symbol random number storage area 52c of the RAM 52, the symbol is stopped and displayed on the ordinary symbol display device 24 based on the ordinary symbol random number. Since the ordinary symbol random numbers stored in the ordinary symbol random number storage area 52c of the RAM 52 are "0" to "255", in the ordinary symbol processing (S13), the ordinary symbol random number stored in the ordinary symbol random number storage area 52c of the RAM 52 is used. When the symbol random number is from “0” to “63”, the symbol is a loss, and the symbol “−” is stopped and displayed on the normal symbol display device 24.

When the ordinary symbol random number stored in the ordinary symbol random number storage area 52c of the RAM 52 is from "64" to "255", the symbol is a win, and the symbol symbol "0" is displayed on the ordinary symbol display device 24. Is stopped. When the winning symbol is displayed on the ordinary symbol display device 24, the opening / closing member (so-called tulip) of the special symbol starting electric accessory 15 is opened for a predetermined time, and the game ball wins the special symbol starting electric accessory 15. It will be easier.

When the ordinary symbol processing (S13) is completed, next, a payout control (S14) for paying out a prize ball is performed, and the processing of the main routine is completed via a frame lamp control (S15). The processing of this main routine, including the processing of each subroutine, is completed within 2 ms. Then, according to a reset signal from the interrupt reset circuit 57,
The CPU 51 executes the processing of the main routine shown in FIG.
Repeat from start. Therefore, the processing of the main routine shown in FIG. 10 is repeated in units of 2 ms. If it is determined in the special symbol processing (S12) of the processing of the main routine of the first round that the state is a big hit state, RA
"1" is stored in the jackpot flag storage area 52f of M52, the jackpot flag is turned on, and in the next condition device processing (S11) in the second round, the jackpot flag storage area 52f is set.
If “1” is stored in f, opening of the special winning opening 16,
The closing operation is performed a predetermined number of times (for example, 15 times or 16 times).

Here, the player operates the firing handle 7 provided on the lower side of the game board 2 to drive the game ball into the game area 4, and the game ball wins the special symbol starting motor-operated role 15. Then, in the switch reading process (S8) of the main routine shown in FIG. 10, winning of the game ball to the special symbol starting electric accessory 15 is detected. Specifically, when the starting port switch 72 provided on the special symbol starting electric accessory 15 detects the passage of the game ball, the big hit determination loop counters respectively stored in the loop counter storage area 52a of the RAM 52. LC2, special symbol creation counters LC3, LC4, LC5, reach judgment counter L
C6, the value of the reach pattern determination counter LC7 is stored as a random number in the special symbol random number storage area 52b of the RAM 52. Then, the process proceeds to S10 via the loop counter updating process (S9). Normally, since no error has occurred in the pachinko machine 1 (S10: NO), the condition device processing (S1
The process proceeds to 1), but since the jackpot has not been determined yet, nothing is performed in the condition device processing (S11), and the special symbol processing (S12) is performed.

In this special symbol processing (S12), FIG.
Big hit determination processing of the flowchart shown in FIG. First, it is determined whether or not a special symbol starting electric accessory 15 is won (S21). This determination is made based on whether or not the number of winning balls stored in the special symbol starting winning number storage area 52d is zero. Special symbol start winning number storage area 52d
If the number of winning spheres stored in the game is "0" (S2
1: NO), end the big hit determination process, and return to the main routine. Special symbol start winning number storage area 52
If it is determined that the number of winning balls stored in d is not “0”, that is, it is one of 1 to 4 (S2
1: YES), the value of each random number stored in the storage area 1 of the special symbol random number storage area 52b is shifted to the determination area and read out, and stored in the storage areas 2 to 4 in the special symbol random number storage area 52b. The storage area is shifted by one for each value of the random numbers (S22). That is, the storage value of the storage area 2 of the special symbol random number storage area 52b is stored in the storage area 1, and the storage value of the storage area 3 is stored in the storage area 2
The storage value of the storage area 4 is moved to the storage area 3. Next, the storage number of the special symbol start winning number storage area 52d is subtracted by "1", that is, the number of winning balls is subtracted (S2).
3).

Next, a jackpot determination is made (S24).
In this embodiment, the value of the jackpot determination loop counter LC2 takes a value between “0” and “299”.
The random number value of the big hit determination loop counter LC2 read into the determination area at step S1 is also one of "0" to "299". Here, the value of the random number read in S22 is a specific value stored in the ROM 53 as a jackpot value,
For example, it is determined whether it is “7”. If the value of the random number read in S22 is “7” (S24: Y
ES), "1" is stored in the big hit flag storage area 52f of the RAM 52 to turn on the big hit flag (S)
25) Next, a jackpot reach pattern selection process is performed based on the value of the reach pattern determination counter LC7 read into the determination area of the special symbol random number storage area 52b (S26).

In the jackpot reach pattern selection process, the jackpot reach pattern table 100 shown in FIG.
, A reach pattern command is selected (S
26) Then, the selected reach pattern command is transmitted from the CPU 51 of the main board 41 to the I / O interface 5.

At the timing of the temporary stop, the background image F is switched to the background image G. In this case, the background image is switched according to the temporary stop of the fluctuating symbol.

Next, the special symbol display sections 27a to 27c
, The left symbol, the middle symbol, and the right symbol start to fluctuate at high speed immediately, and at the timing of T17, the three symbols temporarily stop, and at the timing of the temporary stop of the three symbols, The background image G is switched to the background image H. In this case, the background image is switched according to the temporary stop of the fluctuating symbol. Next, the left symbol, the middle symbol, and the right symbol displayed on the special symbol display portions 27a to 27c are:
Immediately at a high speed, the three symbols temporarily stop at the timing of T18, and the background image H is switched to the background image I at the timing of the temporary stop of the three symbols.

Next, at the timing of T19, as shown in FIG. 45, the symbols displayed on the special symbol display portions 27a to 27c are all rotated at low speed, with the symbols aligned in the forward direction (from top to bottom). Becomes At this time, the display is switched to the background image J of the monochrome flash. In the same manner as described above, the black-and-white flash background image J alternately switches between a white-only background image J1 and a black-only background image J2.
Thereafter, at the timing of T20, the special symbol display section 27a
Through 27c are fixedly displayed, and T21
At the timing of, the background image J is switched to the background image A, and the symbols displayed on the special symbol display sections 27a to 27c are fixedly displayed as “seven, seven, seven”. It should be noted that "7, 7, 7" is merely an example, and if the same pattern is arranged, any pattern such as "3, 3, 3" or "6, 6, 6" may be arranged. .

As described above, in the above embodiment, the background image displayed on the liquid crystal screen 28 of the special symbol display device 8 is switched when the direction of change of the symbol displayed on the special symbol display section is changed. As a result, it is possible to enrich the change of the background image during the game, and to further enhance the interest of the player. The program and data for displaying the symbols based on the reach command received by the symbol display board 44 from the main board 41 are stored in a ROM (not shown) of the symbol display board 44.

The CPU of the symbol display board 44 determines that the reach pattern command is "1 to 53 and 56 to 59".
Is received, various reach operations corresponding to the respective reach pattern commands are performed.

When the above processing is completed, the process returns to S24, and if the random number value of the jackpot determination loop counter LC2 read out in S22 is other than, for example, "7" which is a jackpot (S24: NO), Reach judgment counter L
It is determined whether or not to perform the off-reach operation based on the value of C6 (S31).
In the case of "20 to 39", it is determined that the vehicle is out of reach (S31: YES). If it is determined that there is a miss reach (S31: YES), a miss reach pattern selection process is performed with reference to the miss reach pattern table stored in the miss reach pattern table storage area 53c of the ROM 53 (S32). The operation of the reach symbol change is performed, and finally, the missing symbol is stopped and displayed on the special symbol display portion 27a, the special symbol display portion 27b, and the special symbol display portion 27c in the upper row 25 (S33).

In the symbol stop display process (S33),
