PROBLEM TO BE SOLVED: To prevent the bias of performance patterns in a variable display game. SOLUTION: Performance form determination means includes: a plurality of random number generation means for generating a random number value by respectively different methods; storage means for storing a performance table indicating the relation of the random number value and a performance form in order to determine the performance form on the basis of the random number beforehand; random number extraction means for extracting the random number value from one of the plurality of random number generation means when the start condition of the variable display game is established; and the performance form determination means for selecting the performance form of the variable display game on the basis of the extracted random number value and the performance table. The random number extraction means includes a random number change determination means for determining whether or not to change the random number extraction means to another random number generation means on the basis of a game state.
