PROBLEM TO BE SOLVED: To provide an index for predicting a jackpot expectation degree with unprecedented diversity.SOLUTION: Performance determination means continues, as a variable performance pattern, a plurality of individual variable performances during a period of a symbol variable display corresponding to a single entry of a game ball in an operation-start hole, to temporarily stop the ongoing symbol variable performance at a prescribed timing, and then displays a special variable performance that shows as if a progress of the performance has changed before and after the timing. The variable variation pattern includes, as selection objects, a plurality of special variable performance patterns each of which constitutes each individual variable performance by a combination mode between any of the plurality types of previously provided specific performances and an additional performance that may constitute a part of the specific performance. Transfer possibilities to a special game are different according to types of specific performances, and further, the transfer possibilities to the special game are different according to attributes of the additional performance. Thus, the total transfer possibilities to the special game are different according to the combination between the specific performance and the additional performance. |
