PROBLEM TO BE SOLVED: To provide a pinball game machine that can sufficiently exhibit effect of improving game properties by the combination of so-called a "frequency limit probability variation" function and a "sudden probability variation" function.SOLUTION: A pinball game machine is configured such that a jackpot state for opening big winning means according to a predetermined opening pattern is generated when a symbol becomes a jackpot mode, and a high probability state is generated until a symbol variation frequency becomes a specific frequency after the occurrence of the jackpot state when a predetermined start condition is established. When the start condition is established during the high probability state, a final stage of the specific game state is postponed until the following symbol variation frequency becomes the specific frequency. When the specific start condition of the start condition is established, a specific opening pattern A having difficulty with a game ball winning prize is selected as an opening pattern of the jackpot state. When the specific start condition is established in the specific game state, a specific rendering showing that the final stage of the specific game state is postponed is executed by the final stage of the specific game state in the case where the postponement is assumed not to be present. |
