[0002]

2. Description of the Related Art A pachinko machine has been conventionally known as this kind of ball-and-ball game machine. Conventional pachinko machines are provided with a special symbol display device for displaying a plurality of special symbols in a variation in a gaming section provided on the surface of a game board, and a starting winning port provided separately from a general winning port. Is started on the special symbol display device on condition that the game ball wins. Then, a special symbol display mode of the special symbol display device is determined by lottery using random numbers, and the variable display of the special symbol is stopped based on the determination.

Here, the special symbol display device has a special symbol stopped and displayed in a predetermined prize mode of "big hit".
When it becomes (for example, “7”, “7”, “7”), the player is caused to perform a special game that is more advantageous than the normal game.
In this special game, for example, a large winning opening provided separately from a general winning opening is opened for a predetermined time or until a predetermined number of playing balls are won, so that many game balls are won, and many Prize balls can be obtained.

[0004] The starting winning opening is provided with a variable member which can be switched between a state in which game balls can be easily received and a state in which game balls are not easily received. Has been switched to an unacceptable state.

[0005] Further, a normal symbol display device for variably displaying a plurality of normal symbols is provided in the gaming section.
On the condition that the game ball has passed through the normal symbol starting port provided separately from the general winning opening, the variable display of the normal symbol on the normal symbol display device is started. Then, a normal symbol stop display mode in the normal symbol display device is determined by random selection using random numbers, and the variable symbol display is stopped based on the determination.

In other words, in an extreme case, even if the number of times the special symbol is displayed on the special symbol display device greatly exceeds the number of times the "big hit" should occur, the "big hit" may not occur at all.

As described above, if a "big hit" does not occur at all even if the game is continued for a long time, the player becomes tired of the game, and the fun of the game is spoiled. In addition, a large amount of game balls to be used for the game must be purchased, and the balance between the profits of the game store and the player is lost, and it becomes impossible to play a sound game.

The present invention has been made in view of the above circumstances, and prevents a large decrease in the number of balls held even when a special symbol display device does not have a prize mode despite playing a game for a long time. An object of the present invention is to provide a ball game machine capable of performing a healthy game without impairing the fun of the game.

(S5_8), a normal symbol fluctuation time normal setting process for setting the normal symbol fluctuation time to the normal time (S5
_9) is performed.

Subsequently, it is determined whether or not the stop display mode of the ordinary symbol on the ordinary symbol display device is a hit (S5_10). If the hit is generated, the opening time of the ordinary electric accessory 11 is determined. Is set to the normal time, the normal electric accessory normal setting control process (S5_11) is performed, the winning possibility to the starting winning opening 12 is set to the normal state, and the process returns.

<Probability Selection Table> Next, the high probability selection table and the normal selection table will be described with reference to FIG. In the high probability selection table, as shown in the upper part of FIG. 8, a case where the random number value is “26” to “255” out of 256 random numbers from “0” to “255” is a hit.

On the other hand, as shown in the lower part of FIG. 8, the normal selection table shows a case where the random number value becomes “116” to “255” from the 256 random numbers “0” to “255”. It is a hit. Therefore, when the high-probability selection table is selected, the hit is more likely to occur by about 1.6 times than when the normal-time selection table is selected.

<Normal Symbol Fluctuation Time and Normal Electric Actor Opening Time> Next, with reference to FIG. 9, the ordinary symbol fluctuation time and the ordinary electric auditors character opening time at the time of the high setting and the normal setting will be described. . The special symbol game counter value is "100
If the value is less than "0" and the normal setting is set, the normal setting control is performed, and as shown in the lower part of FIG. The opening time of No. 11 is 0.3 sec.

On the other hand, if the special symbol game counter value is “10”
00, the high setting control is performed when the high setting is obtained, and as shown in the upper part of FIG. 9, the fluctuation time of the normal symbol in the ordinary symbol display device 7 is reduced to 5 sec. The opening time of the electric accessory 11 is extended to 3 seconds.

Therefore, when the high setting control is performed, compared with the case where the normal setting control is performed,
The fluctuation time of the ordinary symbol in the ordinary symbol display device 7 is 1 /
In addition to being reduced to 10, the opening time of the ordinary electric accessory 11 is extended by 10 times. Such processing is performed in order to increase the possibility that the game ball wins the starting winning opening 12 and increase the possibility that the jackpot is generated by that much, and in the case where the jackpot is not configured for a long time. This is because it is possible to continue the game without significantly reducing the number of balls.

That is, up to four passing balls of the symbol starting port 10 can be stored, but if the number of stored balls is the upper limit of four, no more passing balls are stored. Therefore, when the number of stored items is the upper limit value of four, until the end of the display of the change of the ordinary symbol with respect to the first stored value, the ordinary symbol starter 1
Even if the game ball passes through 0, it will be ignored.
Therefore, by shortening the fluctuation time of the ordinary symbol in the ordinary symbol display device 7, the possibility that the passing ball is not stored can be reduced, and the number of times the ordinary symbol can be displayed in the ordinary symbol display device 7 can be increased.

Further, by extending the opening time of the ordinary electric accessory 11, the possibility that the game ball can win the starting winning opening 12 can be increased. Can be increased.

The set value for shifting to the high probability, the normal symbol change time and the normal electric accessory opening time are not limited to those described above, and can be changed as appropriate.

Further, the possibility of winning in the starting winning opening 12 is controlled by controlling the normal symbol fluctuation time and the normal electric accessory opening time, but only one of them may be performed. Further, in addition to or instead of controlling the normal symbol fluctuation time and the normal electric accessory opening time, control is performed so as to change the number of game balls paid out when the game balls enter the starting winning opening 12. Can also.
