PROBLEM TO BE SOLVED: To secure fairness of a game without regularity according to a decision of a prize-winning design. SOLUTION: A game machine for hitting balls has a random number extract means (step 101) for extracting a random number under fixed conditions, a prize-winning judgement means (step 102) for judging a win for a prize when a random number value belongs to a specified prize-winning range after verifying one random number extracted by the random number extract means to a judge table providing a predetermined specified prize-winning range within an entire range of the random number value produced from the random producing means, and a design stop control means (step 105) for stopping to display a stop design corresponding to design information on a design variation display means according to the design information of the prize-winning design memorized in the prize-wining range where the random number value extracted at a judgement of the win for the prize belongs. The prize-wining ranges have two kinds of the prize-wining ranges, one is determined according to a normal prize-wining probability and the other one is determined according to the prize- wining probability different from the normal prize-wining probability. |
