PROBLEM TO BE SOLVED: To reduce a memory capacity of a game machine which performs a lottery by using a random number.SOLUTION: A game machine includes a register value table in which a plurality of register values are defined which indicate a winning region from random number values which can be generated by random number generation means, and a plurality of lottery tables defining a correspondence between a register value number indicating which register value is used from among the plurality of register values, and a winning number indicating a lottery result. Each of the lottery table stores, as lottery data, a number value obtained by the calculation of "X×a+Y", in which X×a+Y≤255 and a>Ymax are satisfied, where X is the register value number, Y is the winning number, Ymax is a maximum value of the winning number, and a is a constant number determined according to the winning number. The game machine includes a first lottery table and a second lottery table which are different at least in a part of the winning number as the plurality of lottery tables. When a first condition is satisfied, a lottery is performed by using the first lottery table, whilst when a second condition is satisfied, a lottery is performed by using the second lottery table.SELECTED DRAWING: Figure 24 |
