PROBLEM TO BE SOLVED: To impartially execute determination on whether it is a probability variation or not in a probability variation judge round, even when a player wins with a symbol preventing transfer to a high probability state.SOLUTION: In a probability variation judge round (non-probability-variation round), a large winning hole solenoid is turned on simultaneously with start (time t1) of the round, and turned off after lapse of 20 seconds (time t10) (A). A probability variation area solenoid is turned on simultaneously with the start (time t1) of the round, and turned off after lapse of 0.1 second (time t2), turned on after lapse of 23 seconds (time t11) from the start of the round, and turned off (B) when the round is terminated at the time t12. In this way, a probability area solenoid 99 is turned on for such a short period (for 0.1 second) that, after starting the round, a game ball does not reach the probability variation area, so as to secure a situation where a variable winning device and the probability variation area are opened during the jackpot game, thereby executing a real probability variation judge round. |
