PROBLEM TO BE SOLVED: To improve the operability of a game machine and increase the profit of a game parlor. SOLUTION: When a start lever is depressed while tokens are bet, the game machine extracts a random number at that point and judges whether the number of tokens credited is 45 or more. When the result of the judgment shows that the number of tokens credited is 45 or higher, the game machine performs a lottery by using a high-probability table. On the other hand, when it is judged that the number of credited tokens is less than 45, the game machine performs a lottery by using a low-probability table. Thus since the probability of winning is changed depending on the number of credited tokens, a player cannot play a game with high probability unless the player sets the number of tokens at 45 or higher. Consequently the game machine can make the player buy a large quantity of tokens, and helps the game parlor increase its profit. COPYRIGHT: (C)2007,JPO&INPIT
