Abstract (en)
Each reel (10) has a code (26 or 28) unique to each of a plurality of angular stop positions of the reel to enable sensing of the random position in which the reel stops. Each code has two series of aperture locations (22, 24) arranged to serially transmit coded information by passing light from sources (14, 16) to receivers (18, 20). Sensing therefore requires to take place just prior to stopping of the reel, with a minimum number of sensing components. A microprocessor is programmed to process the coded information and check for a winning combination of symbols on the reels.
