PROBLEM TO BE SOLVED: To keep player's expectations of a big winning when a game state is controlled to a probability variable state and to improve interest in a game. SOLUTION: A microcomputer 100 for performance control derives and displays a sudden probability variable big winning symbol ("135" for instance) on condition that it is determined to attain a sudden probability variable big winning in the probability variable state, derives and displays the big winning symbol of probability variable symbols (for instance, the state that the same odd-number symbol is arranged for left, center and right performance symbols) on condition that it is determined to attain a probability variable big winning in the probability variable state, and derives and displays the big winning symbol of non probability variable symbols (for instance, the state that the same even-number symbol is arranged for the left, center and right performance symbols) on condition that it is determined to attain a normal big winning in the probability variable state. When deriving and displaying the sudden probability variable big winning symbol using the variation symbol of special PG2-2, the big winning symbol of the non probability variable symbols is tentatively derived and displayed and then the sudden probability variable big winning symbol is derived and displayed.
