PROBLEM TO BE SOLVED: To provide a slot machine that can increase patterns of special winning combination without restricting reel pattern arrangement and reel control as much as possible, does not allow a player to determine whether a special winning combination is won till a continuous performance ends even if the number of continuous games is increased, and can maintain the player's expectation even if a state of not determining to permit derivation of a special display result is continued.SOLUTION: The slot machine includes multiple kinds of special winning combination in which pattern combinations are different from one another and the number of continuous games of continuous performance is defined so as to satisfy Z<X+(Y1+Y2)Z where X represents the number of special winning combination in which operation procedures for winning do not coincide with one another, Y1 represents winning probability of replay role combination during continuous performance, Y2 represents winning probability of small role combination during continuous performance, and Z represents the number of continuous games of continuous performance. In the slot machine, an expectation value (500G) of the number of games required for attaining a peak (1) after the end of BB, RB is different from an expectation value (1065.9G) of the number of games required for attaining a peak (2) after the end of BB, RB. |
