<p><P>PROBLEM TO BE SOLVED: To provide a game machine capable of sufficiently increasing interest in a game. <P>SOLUTION: The game machine is provided with: a variable display means, a variable prize-winning means; an operating means for operating the variable prize-winning means; and a probability varying means for varying a probability of indicating a specific pattern on the variable display means. When the specific pattern is a first probability variation pattern, the operating means operates the variable prize-winning means according to a first operating mode, and the probability varying means varies a probability of indicating the specific pattern later on the variable display means into a high probability. Besides, when the specific pattern to be indicated on the variable display means is a second probability variation pattern, the operating means operates the variable prize-winning means according to a second operating mode, and the probability varying means varies a probability of indicating the specific pattern later on the variable display means into a high probability. When operating the variable prize-winning means according to the second operating mode, a prize-winning rate of a game ball in the variable prize-winning means is then lowered in comparison with a case of operating the variable prize-winning means according to the first operating mode. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
