Here, when the occurrence of a big hit is permitted, a symbol to be a big hit is determined (S64), and a symbol change command for the big hit is generated (S65).

If the occurrence of the jackpot is not permitted, it is determined whether or not a reach effect is performed (S6).
6). Here, in the case of performing a reach effect, a stop symbol is determined so as to be "losing with reach" (S6).
7), a symbol change command for the reach loss is generated (S68).

On the other hand, when the reach effect is not performed,
A stop symbol is determined so as to be "reach without reach" (S69), and a symbol change command for no-reach loss is generated (S70). Then, each procedure described above (S6
The symbol variation command generated in (5, S68, S70) is transmitted to the special symbol control board 32 (S71).

Subsequently, it is determined whether or not a jackpot has actually occurred (S72). 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 (S73), a special symbol game ending process is performed (S74). If no big hit has occurred, the big hit game process (S73) is not performed.

<Conditional gate switch check processing (1)
> Condition gate switch check processing described above (S33)
The starting port switch check process (S34) is a process for determining a random number to be used for jackpot determination based on the game ball detected by the condition gate switch 19. First Embodiment of Conditional Gate Switch Check Process and Startup Port Switch Check Process Based on FIGS.
Will be described.

In the condition gate switch check process and the starting port switch check process according to the first embodiment, a random number used for determining a jackpot is determined based on the number of game balls detected by the condition gate switch 19. In the condition gate switch check process (1) according to the first embodiment, as shown in FIG. 10, it is determined whether or not a game ball has passed the condition gate 18 and has been detected by the condition gate switch 19 (S8).
1) When a game ball is detected by the condition gate switch 19, it is determined whether or not the storage number of the game ball passing the condition gate 18 is an upper limit value (for example, “5”) (S).
82).

If the number of game balls that have passed the condition gate 18 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 18 is at the upper limit, the upper limit is maintained. Also,
When the game ball is not detected by the condition gate switch 19, the above-described processes (S82, S83) are not performed.

If the value is less than the upper limit "5", the special symbol memory 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", the condition gate passage storage value is changed to "00". "1" is subtracted (S95), and a random number for jackpot determination for high probability is obtained (S96).

On the other hand, if 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-hit determination for high probability or large-value jackpot for low probability determination is set in the special symbol storage area corresponding to each special symbol storage counter value (S98), and the process returns.

In the first embodiment described above, two types of random numbers for jackpot determination are used, high probability and low probability. However, three or more types of random numbers for jackpot determination may be used. In this case, the selected random number for jackpot determination may be sequentially changed according to the condition gate passage counter value.
