Abstract

In a slot machine, a specific winning line among a plurality of winning lines, e.g., an effective winning line or a winning line on which a winning symbol array appears, is optically identified. To identify a winning line or lines, series of light emitting diodes are disposed along the winning line or lines to selectively drive and illuminate the diode series. A liquid crystal display panel may be mounted in a display window. In this case, display patterns in front of the symbols are selectively flashed.
