PROBLEM TO BE SOLVED: To enhance interest in a game in a specific game state.SOLUTION: The rate of satisfaction of probability variation control conditions resulting in a varied probability state after completion of a jackpot game state differs according to which of a plurality of major winning holes a game ball enters. For example, even if a jackpot type is determined as a "first jackpot" or a "second jackpot", the maximum number of execution times of round games in the jackpot game state becomes "14". When the number of execution times of round games is "1" to "13", a round game with an upper major winning hole as an open state is executed. When the number of execution times of round games is "14", a round game with a lower major winning hole as an open state is executed. Opening upper-limit time of the major winning hole in a case where the jackpot type is the "first jackpot" is extremely shorter than that in a case where the jackpot type is the "second jackpot". When a specific area switch detects a game ball entering a lower major winning hole, the probability variation control conditions are satisfied. |
