PROBLEM TO BE SOLVED: To increase excitement and enjoyment by varying appearance rate of ready-to-win condition. SOLUTION: A determination ratio showing that variable display condition of ornament symbols are made to be ready-to-win condition becomes higher when within a predetermined period than when out of the predetermined period by the setting of a ready-to-win determination table for example when game condition is in the special game condition such as probability fluctuation condition or time shortening condition. Alternatively, the determination ratio showing that the variable display condition of the ornament symbols are made to be ready-to-win condition may be lower in the predetermined period than without the predetermined period. Thus, the ratio in which ready-to-win condition is established are made different according to the determination result of whether predetermined condition being in the predetermined period is established from an execution number of times of special symbol games in the special game conditions. Further, the determination ratio of the kinds of fluctuation patterns or the fluctuation patterns or the performance modes in the performance action are made different according to whether it is in the predetermined period or not.
