PROBLEM TO BE SOLVED: To provide a game machine capable of reducing the data capacity and controlling the gradation for varying the lightness of light-emitting elements. SOLUTION: A subordinate CPU computes the current value as the grade of lightness based on a function K1 to which the parameter (in this embodiment, the grade of initial lightness and a unit value of increase/decrease stored in ROM to be temporarily stored in RAM) stored in the ROM is given. Then, the subordinate CPU sets the time to turn on the light and the time to turn off the light based on the current value (the grade of lightness) in variable interval processes.
