<P>PROBLEM TO BE SOLVED: To relax influence due to difference in relative spectral sensitivity between colors and a lighting environment concerning impression given to a game player by patterns displayed in multi-color in a game machine. Ž<P>SOLUTION: In the game machine, in order to inform a game player of lottery result on prize, a presentation unit for performing various presentation displays using LEDs of RGB is incorporated. The presentation unit displays various characters, shapes and colors by displaying the LEDs of the respective colors in multi-gradation. In this case, a sub-control board for controlling the display of the presentation unit performs presentation displays by converting the gradation value to restrain the maximum luminance of green (G) to a symbol schedule of presentation display. By this luminance adjustment, influence due to higher relative spectral sensitivity of the G to the R and B is relaxed to give an impression depending on intention in designing symbol data to the game player.
