PROBLEM TO BE SOLVED: To improve the relation between a function to vary probability and a time shortening function to enhance fun. SOLUTION: When the large winning patterns among probability patterns are led out in the respective special pattern display areas 50a-50c of an LCD 32a, probability improving period is generated, the period continues until special patterns vary for 50 times and a high probability state is attained. After they vary for 50 times, the period ends. In the meantime, when the probability improving period starts, a time shortening period is also occured, the period continues until the special patterns vary for 100 times and a time shortening operation is executed. After they vary for 100 times, the period ends. In the case that the large winning patterns among probability variation patterns are displayed again during the probability improving period or the time shortening period, a probability variation counter G or a time shortening variation counter H is reset and counting can be performed from the beginning. In the case that a large winning state is generated during the probability improving period and the time shortening period, a large winning operation is given priority and a high probability operation and the time shortening operation executed in the period can be put in a stop state. |
