Based on arrangement relation of several symbols of the plurality of symbols stopped at the front side of the reels 4a, 4b, and 4c, a determination is made as to whether or not the player has won at least one of predetermined big payoff combinations. If the player has won a predetermined big payoff combination, a predetermined number of tokens corresponding to the big payoff combination are paid out.

Such a slot machine has a built-in controller 7suchas that shown in Fig. 4. Thecontroller 7 controls the operation of the slot machine i. In general, the controller 7 performs a control operation so called as draw-in control operation for drawing reels on the basis of result of internal drawing operation as described below. For example, a plurality of big-payoff combinations have already been set a regular bonus, a big bonus which enables acquisition of a greater number of tokens than in a regular bonus, etc.). Upon commencement of a slot machine game, internal drawing operation is performed, thereby selecting one from the plurality of big-payoff combinations and failures. On the basis of the result of internal drawing operation and the player's actions for actuating the stop buttons 5a, 5b, and 5c, the controller 7 performs a control operation for stopping the reels 4a, 4b, and 4c a draw-in control operation) such that the arrangement relation of symbols on the reels 4a, 4b, and 4c corresponding to the chosen big payoff combination is more easily obtained.
