Since the big hit determination process in 14) has not been performed yet, nothing is performed in the condition device process (S13) and the process proceeds to the next process. Next, special symbol processing (S14) is performed.

In this special symbol process (S14), a jackpot determination process and the like described later are performed. Further, when this special symbol processing (S14) ends, next, the normal symbol processing (S
15) is performed. In this normal symbol processing (S15),
Ordinary symbol hit determination described below is performed.

When the normal symbol processing (S15) is completed, next, payout control (S16) for paying out the prize balls is performed and the process returns to S6. Then, in response to an interrupt reset signal from the interrupt reset circuit 57, the CPU 51 repeats the processing from S7 of the main routine shown in FIG. 8 from the start. Therefore, S7 to S1 of the main routine shown in FIG.
This means that the process of 6 is repeated every 2 ms. If the special symbol processing (S14) of the processing of the main routine is determined to be the big hit state, "1" is stored in the big hit flag storage area 52f of the RAM 52, the big hit flag is turned ON, and in the next condition device processing (S13). If "1" is stored in the jackpot flag storage area 52f, the opening and closing operations of the special winning opening 16 are performed a predetermined number of times (for example, 15 times or 16 times).

Next, details of the lending rate changing process will be described with reference to the flowchart shown in FIG. This lending rate change processing is executed in the main routine shown in FIG.
When the interrupt reset signal is generated, it is set within 2 ms. That is, S7 to S16 of the main routine
It is designed to be performed in parallel with each of the processes.

In the lending rate changing process of the flow chart shown in FIG. 9, one ball 4 provided on the upper plate 5 of the pachinko machine 1 is used.
When the circle rate selection button 5b is operated (S51: Y
ES, S52: YES), the jackpot value data storage area 53d of the ROM 53 from the jackpot value 1 (“7”, “33
3 ”) is selected and stored in the jackpot value storage area 52r of the RAM 52 (S53). Further, when the rate selection button 5c of 1 circle 2 yen provided on the upper plate 5 of the pachinko machine 1 is operated (S51: YES, S52: NO, S54:
YES), the jackpot value data storage area 5 of the ROM 53
Select the jackpot value 2 (“7”) from 3d, and RAM5
2 is stored in the jackpot value storage area 52r (S5
5).

Next, the details of the special symbol processing (S14) will be described with reference to the flowchart shown in FIG. First, it is determined whether or not a random number is stored (S21).
This determination is made depending on whether or not the number of winning balls stored in the special symbol starting winning number storage area 52d is zero. When the number of winning balls stored in the special symbol start winning number storage area 52d is "0" (S21: NO), the jackpot determination process is terminated and the process returns to the main routine.

The number of winning balls stored in the special symbol starting winning number storage area 52d is not "0", that is, 1 to
If it is determined to be one of 4 (S21: YE
S), 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 each is stored in the storage areas 2 to 4 in the special symbol random number storage area 52b. The value of the random number is shifted one by one between the storage areas (S22). That is, the storage value of the storage area 2 of the special symbol random number storage area 52b to the storage area 1, the storage value of the storage area 3 to the storage area 2,
The stored value in 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 reserved balls is subtracted (S23).

Next, it is determined whether or not to perform a shortened variation for shortening the time from the start of variation of the symbols variably displayed on the special symbol display portions L1, L2, L3 to the fixed display (S24).
This determination is performed based on the number of reserved balls (the number of winning balls for which the jackpot determination has not been performed) stored in the special symbol starting winning number storage area 52d. Specifically, the number of reserved balls is 0
In the case of ~ 2, the shortening fluctuation is not performed (S24: NO),
When the number of reserved balls is 3 or 4, shortening fluctuation is performed (S2
4: YES).

When performing the shortening variation (S24: YE
S), a short time base variation command is output from the main board 41 to the symbol display board 44 (S25). When the shortening variation is not performed (S24: NO), the long-term base variation command is output from the main board 41 to the symbol display board 44 (S26).

Output of short-time base fluctuation command (S2
5) or when the output of the long-term base variation command (S26) is completed, the jackpot determination is then performed (S28).
In the present embodiment, the value of the big hit determination random number RN2 is
Since it takes a value between "0" and "629", the value of the random number of the big hit determination random number RN2 read in the determination area in S22 is also "0"-"629". Where S
The value of the jackpot determination random number RN2 read in 22 is determined as the jackpot value, and it is determined whether or not it is the jackpot value stored in the jackpot value storage area 52r of the RAM 52. For example, when renting a game ball at a lending rate of 4 yen per ball and playing, the jackpot value stored in the jackpot value storage area 52r of the RAM 52 is a jackpot value of "7" and "333". ", So S2
The value of the jackpot determination random number RN2 read in 2 is "7"
Or, if it is "333" (S28: YES), it is determined to be a big hit and R is set to turn on the big hit flag.
"1" is stored in the jackpot flag storage area 52f of the AM 52 (S29).

In addition, when renting a game ball at a lending rate of 2 yen per ball and playing, the jackpot value stored in the jackpot value storage area 52r of the RAM 52 is a jackpot value of "7". Therefore, when the value of the jackpot determination random number RN2 read in S22 is “7” (S28: YES), it is determined to be a jackpot, and the jackpot flag storage area 52f of the RAM 52 is turned on to turn on the jackpot flag. "1" is stored (S29). Then
The jackpot reach pattern selection process is performed based on the value of the reach pattern determination random number RN7 read out in S22 (S30).

This jackpot reach pattern selection processing S3
At 0, the variation pattern command of the reach is selected by referring to the jackpot reach pattern table stored in the jackpot reach pattern table storage area 53b shown in FIG. 7, and the variation pattern command of the reach is RA.
It is stored in the symbol variation command storage area 52a of M52 (S30).

Next, a jackpot symbol selection process is carried out (S
31). When performing the jackpot display, the jackpot symbol is selected based on the value of the special symbol creation random number RN3 stored in the special symbol random number storage area 52b. The special symbol creation random number RN3 is any numerical value between "0" and "9".

Here, in accordance with the value of the special symbol creation random number RN3 stored in the special symbol random number storage area 52b, the jackpot symbol is selected as follows (S31).
The value of the special symbol creation random number RN3 and the first stop symbol (left symbol) displayed in the special symbol display portion L1 and the special symbol display portion L2
The second stop symbol (right symbol) displayed in, the relationship with the third stop symbol (middle symbol) displayed in the special symbol display portion L3,
0: “0, 0, 0”, 1: “1, 1, 1”, 2: “2,
2, 2 ", 3:" 3, 3, 3 ", 4:" 4, 4, 4 ",
5: "5, 5, 5", 6: "6, 6, 6", 7: "7,
7, 7 ", 8:" 8, 8, 8 ", 9:" 9, 9, 9 ". The data showing the selected jackpot pattern is RAM
The first stop symbol storage area 52o of 52, the second stop symbol storage area 52p, and the third stop symbol storage area 52q are stored (S31).

In the process of S31, when the value of the special symbol creation random number RN3 is "1, 3, 5, 7, 9", the probability variation mode in which the probability of the next jackpot becomes high is entered. "1" is stored in the probability variation flag storage area 52n of the RAM 52, and the probability variation flag is turned on. Also,
The value of the special symbol creation random number RN3 is "0, 2, 4, 6,
When it is 8 ”, the probability of the next big hit is not high and the mode is the normal mode. Therefore,“ 0 ”is stored in the probability variation flag storage area 52n of the RAM 52 to turn off the probability variation flag.

In the determination of S28, if the value of the random number of the jackpot determining random number RN2 read out in S22 is other than the jackpot value (S28: NO), S22.
Depending on the value of the reach determination random number RN6 read in step S7, it is determined whether or not the reach operation is performed (S32). When the value of the reach determination random number RN6 is “20 to 39”, it is determined to be out of reach (S32: YES). When it is determined to be out of reach (S32: YES), S22
Based on the special symbol creation random number RN3 and the special symbol creation random number RN4 read in, the stop symbol of the outlying reach is RAM
The first stop symbol storage area 52o of 52, the second stop symbol storage area 52p and the third stop symbol storage area 52q are respectively stored, and also the detachment reach pattern table stored in the detachment reach pattern table storage area 53c of the ROM 53. With reference to, the variation pattern command of the outlying reach is selected, and the variation pattern command of the reach is the symbol variation command storage area 5 of the RAM 52.
2a is stored (S33).

Next, when the reach is not determined in the determination process of S32 (S32: NO), the special symbol creation random number RN3 and the special symbol creation random number RN read in S22.
4, based on the random number of the special symbol creation random number RN5, the detachment stop symbol creation process (S34) is performed, and the first in the RAM 52.
Stop symbol storage area 52o, second stop symbol storage area 5
2p and the third stop symbol storage area 52q are stored (S34). When the processing of S31 or S33 or S34 is completed, next, a symbol designating command for designating a stop symbol to be confirmed and displayed on the symbols of the special symbol display portions L1, L2, L3 is output to the symbol display board 44 (S35). This symbol designating command is the first stop symbol storage area 52 of the RAM 52.
Output based on the stop symbols stored in the o, the second stop symbol storage area 52p and the third stop symbol storage area 52q.

Then, a variation pattern command output process is performed (S35). In this variation pattern command output process, the variation pattern command of the symbol stored in the symbol variation command storage area 52a of the RAM 52 of the main board 41 is output to the symbol display board 44. When the reach variation pattern command is stored in the symbol variation command storage area 52a of the RAM 52, the reach variation pattern command is output from the main substrate 41 to the symbol display substrate 44,
If the reach variation pattern command is not stored, the normal variation variation pattern command is output from the main board 41 to the symbol display board 44 (S36). On the symbol display board 44, based on the variation pattern command received from the main board 41, according to the symbol variation data stored in the ROM (not shown), the symbols of the special symbol display portions L1, L2, L3 of the special symbol display device 8 described later. Control the fluctuations of.

Next, from the main board 41 to the pattern display board 44
The first symbol stop command to the third symbol stop command for stopping the first symbol to the third symbol which are variably displayed on the special symbol display portions L1, L2 and L3 are sequentially output (S3
6, S37, S38). When the first symbol stop command to the third symbol stop command are received, the symbol display board 44
Is a special symbol display portion L1, L2 of the special symbol display device 8.
At L3, the first to third stop symbols are stopped.
