PROBLEM TO BE SOLVED: To provide a game machine which is rich in game features by randomly setting the shooting intervals of game balls. SOLUTION: The shooting interval t2 between the first and the second shots, and the interval t3 between the 99th and the 100th shots are set at random, and an operation for shooting the game balls is automatically performed at random shooting interval, so that rich game property is obtained owing to the random shooting interval of the game balls ((b) in Fig. 18). When it is not determined that a big hit occurs within a prescribed period, a main control part 200 successively adopts different shooting patterns to control shooting the game balls. Thus, game features are more improved. COPYRIGHT: (C)2004,JPO
