PROBLEM TO BE SOLVED: To prevent players' expectations from being drastically lowered, and results contrary to their expectations from occurring frequently as much as possible. SOLUTION: An expected value of a premonitory performance before/after a ready-to-win state is not randomly selected but managed by a performance drawing table in advance for performance variation of patterns. A plurality of performance drawing tables are prepared for each condition such as a game situation, number of times for variation, performance in action at present or the like so as to manage the expected value of the premonitory performance by the table set for the each condition. For example, a selected ratio for a premium premonitory performance of a high expected value for a definite jackpot with probability change is higher in an "odd number winning table for a high probability".
