PROBLEM TO BE SOLVED: To prevent non-uniformity of a performance pattern in a variation display game. SOLUTION: A performance mode determination means includes random number generation means, storage means, random number extraction means, performance mode determination means, initial value generation means and initial value setting means; wherein the random number generation means is adapted to generate a result of a prescribed computing of the initial value as a random number value when the initial value setting means sets the initial value, and to generate a result of the prescribed computing of the random number which the random number generation means generates in the previous time, when the initial value setting means sets no initial value.
