PROBLEM TO BE SOLVED: To enhance amusement of a game in a probability variable state.SOLUTION: In a slot machine performing lottery of combinations for each execution of a game, the combinations include a normal combination and a special combination. The slot machine comprises: special game state generating means (a game control device 50) capable of generating a special game state in which winning of the normal combination is established at a higher frequency than the normal game state with winning establishment of the special combination; and probability variable state generating means (the game control device 50) capable of generating the probability variable state in which the special combination is won at a higher probability than the normal game state. As winning modes of the special combination, single special winning in which the special combination is won singly and duplicate special winning in which the normal combination and the special combination are won duplicately are provided. The probability variable state generating means (the game control device 50) makes a winning probability of the duplicate special winning higher than the normal game state while maintaining a winning probability of the single special winning at the same probability as the normal game state in the probability variable state. |
