Abstract
A backlight for a reel assembly is disclosed comprising a plurality of light emitting diodes (LEDs). An array of red, green, and blue diodes are positioned behind a translucent reel strip to backlight three adjacent symbols on a reel strip. The LEDs are individually controllable to vary the color output of the LED array for a full spectrum of colors including white. Groups of LEDs can be illuminated to optimally illuminate any number of symbols of any size. The LEDs may be controlled to highlight special symbols such as by blinking or changing colors. LEDs are also arranged on both sides of the reel strip in a vertical array so as to outline the edges of the reel strip.
