PROBLEM TO BE SOLVED: To simply diversify the variation times of special symbols. SOLUTION: A win/failure lottery section 112 draws a win/failure lottery triggered by an entry of a game ball in an operation-start hole 62. A special game control section 120 variably displays the special symbols indicating a result of the win/failure lottery. A pattern lottery value acquisition section 140 acquires a pattern lottery value for determining a basic variation time of the special symbols. A symbol lottery value acquisition section 142 acquires a symbol lottery value for determining stop symbols of the special symbols. The symbol lottery value is associated with a compensation time. A variation time specification section 144 determines the variation time of the special symbols by adding and subtracting the compensation time according to the symbol lottery value with respect to the basic variation time.
