PROBLEM TO BE SOLVED: To cause a scene making a player guess whether the game condition is a high probability drawing condition to well arrive while suppressing an opportunity to acquire prize balls from significantly increasing during a game under the condition that a structure making prize balls to be acquired in a winning game is adopted. SOLUTION: In every winning game, a special 2R probability variation jackpot game and a special 2R non-probability variation jackpot game which have the same specified round count as the 2R probability variation jackpot game and permit more prize balls to be acquired than those games and makes their kinds difficult to discriminate from each other are provided in addition to a 2R probability variation jackpot game and a small win game which make their kinds difficult to discriminate from each other. Consequently, even if the arrival of the scene making the player to guess whether the game condition is a probability variation condition is increased by making the small win game easy to appear, the game machine can suppress the opportunity of acquiring prize balls from increasing significantly. Consequently, even if structured so as to permit prize balls to be acquired in the jackpot games having the specified round count of 2, the game machine can cause the scene making the player to guess the probability variation condition to well arrive while suppressing the opportunity of acquiring prize balls from significantly increasing.
