Abstract
A slot machine 10 includes: reels 101-105 each having symbols 501; backlight devices M7 which individually light the symbols 501; a display window 150 which displays the symbols 501; and a motherboard 70 programmed to run a game in which the reels 101-105 are rotated to rearrange the symbols 501, and a prize is awarded according to a combination of the symbols 501. The motherboard 70 (a1) drives and rotating the reels 101-105; (a2) stops the rotation of a predetermined reel; (a3) causes a backlight source M70 of a backlight device M7, which corresponds to a winning-related symbol 501 out of the symbols 501 rearranged, to be in an on-state while causing a backlight source M70 of a backlight device M7 corresponding to a non-winning-related symbol 501 to be in an off-state; and (a4) executes (a3) every time the rotation of at least one of the reels 101-105 is stopped.
