Along with the symbol display section 60 that is finally stopped and displayed, the appearance probability of both stop modes of the reach stop mode in which the stop display is performed after changing to a reach fluctuation speed slower than the normal speed (for example, “512 msec / 1 symbol”) (In the present embodiment, “normal stop mode: reach stop mode = 100: 1”) is stored, and the reach probabilities of both stop modes stored in the normal probability table 84 are compared to reach. The probability of occurrence of the stop mode is high (in the present embodiment, “normal stop mode:
High probability table 85 set to reach stop mode = 10: 1 "), and the number of times the symbol display device 21 starts changing the symbols after the special game performed by the special game executing means 83 is finished. A fluctuation start counter 86 for counting,
On the condition that the special game by the special game executing means 83 is completed, the normal probability table 84 is switched to the high probability table 85, and after the special game is completed,
The high probability table is returned to the normal probability table 84 from the high probability table 85 by the table selection means 87 and the table selection means 87 on condition that the number of times the symbols start to change has reached a predetermined number, for example, four times. On condition that the normal probability table 84 is returned from 85, the counter reset means 88 for resetting the count value by the fluctuation start number counter 86, and the combination of the stop symbols determined by the stop symbol determination means 82, the last When the combination of the stop symbols of the other symbol display portions 61 except the symbol display portion 60 for stopping the variable display matches the combination of the symbols constituting the special prize mode, the table selection means 87 selects The stop mode determining means 89 for determining the stop mode based on either the high probability table 85 or the normal rate table 84, and the stop mode. According stop mode determined by the constant unit 89, and variable control means 90 for controlling the variable display of the symbols by the symbol display device 21, and a.

In the normal rate table 84, for example, a normal stop mode appearance area in which a normal stop mode appears in the entire area of the random number value generated from the random number generating means 80,
It has two areas, a reach stop manner appearance area in which the reach stop manner appears, and this ratio is, for example, “normal stop manner appearance area: reach stop manner appearance area = 100: 1”.

The high-probability table 85, like the normal rate table 84, has a normal stop mode appearance area in which a normal stop mode appears in the entire area of a random number value generated from the random number generating means 80, for example. And a reach stop manner appearance area in which the reach stop manner appears, and this ratio is, for example, “normal stop manner appearance area: reach stop manner appearance area = 10: 1”.

Further, the stop mode determining means 89 compares one random number value extracted by the random number extracting means 81 with the normal rate table 84 or the high probability table 85, for example.
Then, as a result of the collation, the stop mode determination means 89 determines that the stop mode is the normal stop mode if the random number value belongs to the normal stop mode appearance area. On the other hand, when the random number value belongs to the reach stop mode appearance area, the stop mode determination means 89 determines the stop mode as the reach stop mode.

Next, the operation of the pachinko machine 10 having the above-described structure is shown in FIGS. 5 and 6 from the time when a special game started for the first time after the pachinko machine 10 starts its operation. This will be described using a flowchart. First, in step 10, a special game is started, and by opening the opening / closing door 51 for a predetermined time, for example, 29.5 seconds at a time, it is possible to easily enter the game ball into the variable winning device 50. The game to be played is played a predetermined number of times, for example, 16 times.

When the special game is finished in step 10, the process proceeds to the next step 11. In this step 11, the probability table for determining the stop mode of the symbol variation is switched to the high probability table 85. Note that this step 11
In the state before switching to the high probability table 85, when the stop mode of the symbol variation is determined using the high probability table 85, substantially the same result is obtained without switching the table.

Next, in step 12, step 1
2, the counter reset means 88 causes the fluctuation start number counter 86 to have a predetermined number, for example, “+” in the present embodiment.
4 ”is set. Next, from step 12 to step 13, it is determined whether or not a game ball has entered the starting opening 30. This determination is made by the electric control device 70,
In the electric control device 70, the presence or absence of the output of the detection signal from the ball entrance sensor 31 provided in the starting opening 30 is constantly monitored.

When the entry of a game ball is detected, step 1
3 to the next step 14. In the 14 steps, the random number extraction means 81 extracts one random number value from the random numbers generated by the random number generation means 80 on condition that the detection signal from the ball entrance sensor 31 is input. Then, the stop symbol determination unit 82 collates the random number value extracted by the random number extraction unit 81 with a predetermined determination table, and as a result of collation with this determination table (not shown), determines a combination of corresponding stop symbols. To do.

When the stop symbol is determined in this step 14, the process proceeds to the next step 15, and the stop mode of the symbol variable display is determined. The determination of the stop mode of the variable display of symbols is performed as follows. First, in the combination of the stop symbols determined by the stop symbol determination means 86, the combination of the stop symbols of the other symbol display units 60 except the symbol display unit 60 which finally stops the variable display is a symbol constituting a special prize mode. If the combination does not match, the normal stop mode is determined.

On the other hand, when the combination of the stop symbols of the other symbol display portions 60 except the symbol display portion 60 which finally stops the variable display is the same as the combination of the symbols constituting the special prize mode, The stop mode determination means 89 determines the stop mode. The stop mode determining means 89 determines the stop mode by referring to one random number value extracted by the random number extracting means 80 with the high probability table 85 switched by the table selecting means 87. As a result of the reference, when the random number value belongs to the range of the normal stop mode, it is determined to be the normal stop mode, while the random value is
If it belongs to the reach stop mode, the reach stop mode is determined.

When the stop symbol and the stop mode are determined in this step 15, the process proceeds to the next step 16. In this step 16, the fluctuation control means 90 controls the variable display of the symbols on the symbol display device 21 based on the determination in step 15. Specifically, the variable display of the symbols by the symbol display device 21 is started, and when a predetermined time elapses, based on the stop mode determined by the stop mode determination means 89, the variable display of the symbols is stopped, and the stop symbols are also displayed. The symbols are stopped and displayed so as to correspond to the stopped symbol combination determined by the determination means 82.

In step 16, when the variable display of the symbols is stopped, the process proceeds to step 17 shown in FIG.
In step 17, it is determined whether or not the winning, that is, whether or not the combination of the stopped symbols corresponds to the combination of the symbols forming the special prize mode. This judgment is made by the electric control device 70.
Special game execution means of the electric control device 70 performed by
In 83, it is monitored whether or not the combination of the stopped symbols is the combination of the symbols forming the special prize mode.

In this step 17, when it is determined that the winning is not won, that is, when it is determined that the combination of the stopped symbols is other than the combination of the symbols forming the special prize mode, as shown in FIG. , And proceed to the next Step 18. In this step 18, the stop mode determining means 89
In, it is determined whether or not the stop mode is determined using the high probability table 85. This determination is performed by the electric control device 70, and the table selecting means 87 of the electric control device 70 is used.
In, the stop mode determination means 89 monitors whether or not the high probability table 85 is used.

When it is determined in step 18 that the stop mode is determined using the high probability table 85, the process proceeds to the next step 19, and in step 19, from the counter value of the fluctuation start number counter 86, Subtract 1 ". When "1" is subtracted from the counter value of the fluctuation start number counter 86 in step 19, the process proceeds to step 20. In step, it is determined whether or not the counter value of the fluctuation start number counter 86 is "0". This determination is performed by the electric control device 70, and the table selection means 87 of the electric control device 70 monitors whether or not the counter value of the fluctuation start number counter 86 is “0”.

When it is determined in step 20 that the counter value of the fluctuation start number counter 86 is "0", the process proceeds to the next step 21. In this step 21, the table selecting means 87 sets the high value. The probability table 85 is switched to the normal probability table 84. When the normal probability table 84 is switched to the high probability table 85 in step 21, the process returns to step 13 shown in FIG.

In step 20 described above, it is determined that the counter value of the fluctuation start number counter 86 is not "0", that is, the counter value is "1", "2", or "3". If so, the process returns to step 13 shown in FIG. In addition, step 18 described above
If it is determined that the high-probability table 85 is not used, the process immediately returns to step 13.

Further, in step 17 described above, when it is determined that the prize is won, that is, the combination of the stopped symbols is, for example, as shown in FIG. 3, a combination of symbols forming a special prize mode. If it is determined, FIG.
Return to step 10 shown in. In the above-described embodiment, the reach stop mode is such that, regarding the symbol display unit 60 that is finally stopped and displayed, the reach variation speed (eg, “512 msec / 1 symbol”) lower than the normal speed is changed and then stopped. Although it is explained that the display is made to be displayed, the fluctuation speed to be changed from the normal fluctuation speed may be a fluctuation speed different from the normal fluctuation speed, and for example, it may be changed to a slower super reach fluctuation speed (“1024 msec / 1 symbol”). Alternatively, from the normal fluctuating speed, it may be temporarily stopped, and the symbols 1-2 may be variably displayed again and then the symbols may be stopped and displayed. In addition, for example, on the contrary, a high speed fluctuation (for example, 128 msec / 1 pattern) that is faster than the normal fluctuation speed may be used.
