Next, it is determined whether or not the opening time T is within a predetermined opening time (specified time) of the lower movable piece 17b (step S5). If it is determined as No (the opening time T exceeds the specified time) in step S5, the lower movable piece 17b is closed and one opening operation of the lower movable piece 17b is completed (step S6), and the process returns to step S1. Return.

When it is determined in step S5 that the answer is Yes (the opening time T is within the specified time), it is determined whether or not the lower switch 26b is turned on (that is, the game ball has passed through the lower big winning opening 25b). A determination is made (step S7). If No is determined in this step S7, the process returns to step S5, and this step S7 is executed until the opening time T exceeds the specified time.

It is determined as Yes in step S7 (in this case, since the game ball has passed through the lower big winning opening 25b,
It is in a state where winning in the V zone 13 is expected. ) And V zone 1 to determine whether or not a prize has been won in V zone 13.
The determination is made based on the signal of the detection sensor provided in the third prize 3 (or the detection sensor provided in the normal winning opening 14) (step S8). No in step S8 (the ball has entered the normal winning opening 14, ie,
If it is determined that the winning is not made in the V zone 13), a payout process is performed according to the ball entering the normal winning opening 14 (step S).
9) Return to step 1. If it is determined to be Yes (win in the V zone 13) in step S8, the big hit subroutine shown in FIG. 4 is executed (step S10), and thereafter,
The process returns to the main routine (not shown).

On the other hand, if it is determined in step S2 that the starting port into which the game ball has entered is the central starting port 8, first, is the number n of operations indicating the number of times the lower movable piece 17b is opened is 2? It is determined whether or not it is (step S11). Step S1
If it is determined Yes in step 1 (the number of operations n is 2), the lower movable piece 17b is closed, and the opening operation of the lower movable piece 17b is ended twice (step S12), and the process returns to step S1.

If it is determined as No (the number of operations n is not 2) in step S11, the lower movable piece 17b is opened.

If it is determined as No (the opening time T exceeds the specified time) in step S16, the lower movable piece 17b is closed once, and one opening operation of the lower movable piece 17b is terminated. The opening time T started in step S14 is reset (for example, T = 0), and the lower movable piece 17 is set.
It becomes in a state of waiting for the second opening operation of b (step S17), and returns to step S1.

If it is determined Yes (the opening time T is within the specified time) in step S16, it is determined whether or not the lower switch 26b is turned on (that is, the game ball has passed through the lower big winning opening 25b). A determination is made (step S18). If No is determined in this step S18, the process returns to step S16, and this step S18 is executed until the opening time T exceeds the specified time.

If the determination is Yes in step S18, step S19 is executed as in step S8, and step S20 is executed as in step S9.
If “Yes” is determined in step S19, the process proceeds to step S19.
Proceed to 10 (big hit subroutine).

When the player wins the V zone 13 as described above, the big hit subroutine (step S10) is executed. In this jackpot subroutine, first, as shown in FIG. 4, the open pattern determination symbols (10 symbols from 0 to 9) displayed on the variable symbol display section 12 have an even number of five patterns (0, 2, 4, 6, 6). 8) or one of five odd numbers (1, 3, 5, 7, 9) (step S30). If it is determined to be an even number, the lower movable piece 1
7b is opened, and if it is determined to be an odd number,
7a (opening the upper movable piece 17a has a higher probability of winning in the V zone 13 than opening the lower movable piece 17b as described above), When the open pattern determination symbol is an odd number, it is in a more advantageous state than when it is an even number. Hereinafter, the case where the open pattern determination symbol displayed on the variable symbol display unit 12 is determined to be an even number and the case where it is determined that the symbol is an odd number will be described in this order.
