PROBLEM TO BE SOLVED: To provide a slot machine wherein remarkable unfairness due to the bias of winning does not occur. SOLUTION: In a normal game, the cumulative payout number/cumulative input number of coins are calculated (S175F), the calculated value is compared with a standard value being 0.4 or 0.5 (S175H and S175J). A small role judgment mode is set at the high probability time or the normal time based on the compared result (S175I and S175K), and the control of feeding back the generation probability of a specified display form based on the display result of a variable display device is performed.
