DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine which makes a winning hole open when a big hit occurs and makes it easy to win a game ball.

[0002]

2. Description of the Related Art On a game board, for example, a symbol variation display device such as a CRT, a start winning port and a large winning port are provided, and when a game ball wins or passes through the startup winning port, a display symbol of the symbol variation display device such as a CRT is displayed. Fluctuates with a predetermined probability (for example, a probability of 1/250) after a predetermined period of time, "111",
2), "333", "777", "★★★", etc., stop when aligned with the jackpot pattern, and the jackpot will be in a jackpot state. The opening and closing door of the jackpot will be opened by the operation of the solenoid, and the game ball will enter extremely. It becomes easy to win, and a certain number (for example, 10) of prizes are won in the special winning opening, or the closed winning state is established after 30 seconds have passed. ), The special winning opening is re-opened (referred to as the second round), so that the gaming balls can be very easily won again, and a certain number of winnings can be made in the special winning opening. Or the opening state continues until the elapse of 30 seconds, and in the meantime, when the game ball wins in the continuous winning opening, the opening is further continued (referred to as a third round), and thereafter, a certain number of times (for example, the third round). 16 rounds The large winning hole is opened to the final round) a limit, as a result, the player pachinko machine to be able to acquire a large number of prize balls during the jackpot period is as well known.

[0003] The jackpot symbol is, for example, "11
1 "," 333 "," 555 "," 777 "," 99 "
In the case where the jackpot symbol is a specific symbol such as an odd number such as "9", the probability that the next jackpot symbol will be aligned after the above jackpot state (ie, the jackpot occurrence probability) is high. (For example, 1/25), and as a result, a so-called probability-variable pachinko gaming machine in which a big hit occurs continuously many times is also known.

[0004]

However, as in the above-mentioned conventional example, once a jackpot is generated, a probability-variable pachinko gaming machine is configured so that the jackpot is likely to continue to occur afterwards due to some accidental factor. However, several jackpots can be picked up in succession (so-called tan-chan), which greatly inspires the gambling of the player, thereby increasing gambling and improving the soundness of pachinko games as entertainment. There was a problem of being damaged.

Therefore, the present invention restricts the setting of the high probability so that it does not continuously exceed a certain number of times, so that the ambition is not incited as described above.

To get. Then, the obtained jackpot selection random value R
It is determined whether 1 is a predetermined jackpot value,
If it is not a jackpot, the display symbol selection circuit unit 19 selects the lost symbol selected by the jackpot symbol selection random value R3 in step f and displays the lost symbol on the symbol variation display device 11 via the display drive circuit unit 20. I do.

If it is a big hit here, the high-probability mode continuation number H is set to a predetermined number (for example, 5) at step g.
It is determined whether the number of times has not reached the number of times. If the number of times has not reached, the process goes to the normal symbol folder 25 in step h, and the big hit symbol is selected according to the big hit symbol selection random value R2 shown in Table 1 and the big hit occurrence probability is determined. The setting factor of the mode M is selected (step i), and the selected big hit symbol is displayed on the symbol variation display device 11 in step l. In this case, the setting factor of the probability mode M may be a high probability or a low probability.

On the other hand, if the number of continuous high-probability modes H has reached the predetermined number, the emergency symbol folder 26 in step j is used.
And the jackpot symbol and the probability mode setting factor are selected according to the jackpot symbol selection random value R2 shown in Table 2,
The jackpot symbol is a symbol variation display device 1 in step l.
1 is displayed. The setting factor of the probability mode M selected at this time is always a low probability regardless of the value of the jackpot symbol selection random value R2.

Next, at step m, a series of big hitting processes including the opening of the big win 10 and the blinking of the lamp 7 by the big win opening / closing control circuit 31 are performed. Then, in step n, it is determined whether the set factor selected in step k or i is high probability or low probability, and if it is a high probability factor, in step o, the probability changing circuit unit 24 A command is issued to set the jackpot occurrence probability mode M to a high probability. In step g, 1 is added to the number of continuous high probability modes H, and the process returns to step c. If it is a low probability factor, the probability changing circuit unit 24 issues a command to the lottery circuit unit 18 in step p to set the jackpot occurrence probability mode M to low probability, and then returns to step b.

The special winning opening opening / closing control circuit 31 displays the number of continuous high probability mode H on the count value display section 30 provided in a part of the symbol variation display device 11 via the display drive circuit section 20. The player can know the current situation as game information.

As described above, according to the present invention, when the number of consecutive high-probability modes H reaches a predetermined number, the setting factor of the occurrence probability mode M and the big hit symbol are selected from the emergency symbol folder 26. Is not repeated many times. This is effective in reducing the gambling color of pachinko games.

[0018]

As described above, according to the present invention, in a pachinko game machine in which the probability of occurrence of a jackpot varies, it is possible to prevent the occurrence of a jackpot when the high probability mode is continuously exceeded a predetermined number of times. As a result, it is naturally prevented that the gambling of the player is excessively instigated, which is beneficial for maintaining the soundness of the pachinko game as entertainment.
