PROBLEM TO BE SOLVED: To restrain a drop in interests by reducing the monotonousness of games. SOLUTION: A performance is conducted in a prescribed performance mode per game according to a winning combination selected out by an internal lottery carried out per game. When a prescribed prize winning combination is selected out by the internal lottery, it is determined depending on selection probabilities different from each other which should be the one out of a plurality of performance modes. A lottery is carried out for the execution of a supreme performance at a prescribed probability and when the lottery is won, a game is carried out to avoid the end of the replay time continuable until a bonus combination is selected out by the internal lottery. In this manner, at least in the normal game state, the game can be controlled to a supreme lottery state which makes the decision easier on the execution of the supreme performance by the lottery or a normal lottery state which makes the decision harder on the execution of the supreme performance by the lottery as opposed to the selection probabilities of the performance modes.
