PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing deterioration of game interest, in a mission performance to impart an achievement condition to a player. ! SOLUTION: First performance form determination means 2958a presents a set frequency of a variation performance in a performance start, and thereafter determines a performance pattern of a "huge chance" performance that is a performance to execute whether or not a ready-to-win state is formed on an effective line within the set frequency of the variation performance, at a prescribed ratio. First performance display control means 2975a can change performance content related to a normal ready-to-win performance or the like that is a part of performance content set in a variable display pattern into performance content of the "huge chance" performance and can execute it while holding a variation time of a special symbol set in the variable display pattern on the basis of the performance pattern of the "huge chance" performance. !
