Abstract

A game machine has a win judgment table. The table stores win information corresponding to each integer in a range of integers. An integers assigned to one special win paying the largest prize is located at the end of the range of integers. In the first game of a win cycle, one integer is randomly selected from the range of integers, and the win information corresponding to this integer is used to determine the outcome of the first game. In each subsequent game of said win cycle, the integer used to determine the outcome of the previous game is incremented and the resulting integer used for the current game. When the end of the integer range is reached, the special win occurs, and the next game becomes the first game of a new win cycle. It is thus assured that the special win occurs in each cycle of games, and that the number of games between special wins never exceeds a certain value. PAC BACKGROUND OF THE INVENTION The present invention relates to a win control method and apparatus for a game machine, and more particularly to a method and an apparatus capable of generating a special win with an ensured frequency. A typical such game machine is a slot machine and the present inven…
