If a jackpot has occurred, a jackpot game process for opening the special winning opening 13 for a predetermined time and a predetermined number of times is performed. After that (S63), a special symbol game end process is performed (S64). If no big hit has occurred, the big hit game process (S63) is not performed.

<Grand prize opening switch check processing> In the above-mentioned grand prize opening switch check processing (S31), FIG.
It is determined whether or not the game ball has passed through the special winning opening 13 and detected by the special winning opening switch 18 (S7).
1), every time a game ball passes through the special winning opening 13, it is determined whether or not the special winning opening storage counter value is the upper limit value (S7).
2).

If the special winning opening storage counter value is not the upper limit value, the special winning opening storage counter value is incremented and updated (S73), and the conditional gate passage storage counter value is updated by incrementing (S73). S7
4). When the special winning opening memory counter value has reached the upper limit value, the special winning opening memory is incremented (S
73) is not performed.

If the special winning opening switch 18 does not function as a condition gate switch, the condition gate passing counter value is not incremented (S74).

<Conditional Gate Switch Check Processing> The above-described conditional gate switch check processing (S33) and start port switch check processing (S34) are used to determine a jackpot based on a game ball detected by the conditional gate switch 19. This is a process for determining a random number.

When the special winning opening switch 18 is made to function as a conditional gate switch, the conditional gate switch check processing (S33) is not performed and the conditional gate switch is checked in the above described special winning opening switch check processing (S31). Check.

The condition gate switch check process and the starting port switch check process will be described with reference to FIGS. The condition gate switch check process and the starting port switch check process determine a random number to be used in a jackpot determination based on the number of game balls detected by the condition gate switch (V count switch 19).

That is, in the condition gate switch check process, as shown in FIG. 10, the game ball passes through the condition gate and passes through the condition gate switch (V count switch 19).
Is determined (S81), and if a game ball is detected by the condition gate switch (V count switch 19), the number of game balls that have passed the condition gate is set to the upper limit (for example, “5”). )) Is determined (S82).

If the number of game balls that have passed the condition gate is not the upper limit, the condition gate passage storage counter value is incremented and updated (S83). On the other hand, when the number of stored game balls that have passed the condition gate is at the upper limit, the upper limit is maintained.

If no game ball is detected by the condition gate switch (V count switch 19), the above-described processes (S82, S83) are not performed.

<Starting Port Switch Check Processing> In the starting port switch checking processing, as shown in FIG. 11, it is determined whether or not a game ball has won the starting winning port 12 (S9).
1) If the game ball does not win in the starting winning opening 12,
Return processing.

On the other hand, when the game ball has won the starting winning opening 12, it is determined whether or not the special symbol storage counter value is less than the upper limit value "5" (S92), and the upper limit value is "5". If the value is less than the upper limit value "5", the process is returned, and if the value is less than the upper limit value "5", the special symbol storage counter value is incremented and updated (S93). In other words, the number of winning balls in the starting winning opening 12 is held and stored with "5" as an upper limit.

Subsequently, it is determined whether or not the condition gate passage storage counter value is "00" (S94). If the condition gate passage storage counter value is not "00", """1" is subtracted (S95), and a random number for jackpot determination for high probability is obtained (S96).

On the other hand, when the value of the condition gate passage storage counter is “00”, a random number for large probability determination for low probability is obtained (S97).

Subsequently, the acquired random number value for large probability determination for high probability or large value for large size jackpot determination is set in the special symbol storage area corresponding to each special symbol storage counter value (S98), and the process is returned. .

As described above, in the ball game machine according to the present invention, in the variable winning opening which can be switched between the first state in which game balls are easily accepted and the second state in which game balls are hardly accepted, A condition gate through which a game ball passes is provided, and a winning probability for shifting to a special game is changed based on the game ball passing through the condition gate.

Therefore, even if the so-called probability fluctuation in which the winning probability for shifting to the special game is raised is not so high, the winning probability for shifting to the special game may increase, so that the player gets tired of the game. Without
Since the winning probability for shifting to the special game changes, the expectation for the occurrence of the special game changes, and the fun of the game can be sufficiently enjoyed.

The variable winning opening can be switched between a first state in which game balls can be easily received and a second state in which game balls cannot be easily received. The game ball must be guided to the variable winning opening in anticipation of the timing when the game ball is in the first state in which the game ball can easily be received, so that the player's technical intervention is possible and the fun of the game can be enhanced.

Further, by providing a condition gate in a specific area where game balls in the variable winning opening are difficult to pass, the degree of technical intervention of the player is further increased, and the fun of the game can be further enhanced.

Further, according to the recording medium on which the game program according to the present invention is recorded, a game program capable of playing the same game as the above-described ball game machine is used as, for example, a game program for a home game machine. can do. In addition, in the home game machine, the same game as the above-described ball game machine can be enjoyed.
