PROBLEM TO BE SOLVED: To achieve higher performance effects in related performances to be carried out over a plurality of variable displays. SOLUTION: The first or second reservation status is retained according to the starter slots won by game balls. The processing of the second reservation status is made preferentially to the first preservation. In the retention of the first or second reservation status, the first or second related performances can be executed as done over a plurality of varying operations until the processing of the first or second reservation status is completed after the retention of the first or second reservation status. When the second reservation status is retained during the execution of the first related performances, prescribed performances making up the first related performances are executed during the variable display of special figures based on the second reservation status. The probability of executing the first related performances is higher in the non-time shortening game state and lower in the time shortening game state as compared with that for the second related performances.
