Abstract

A slot machine device comprises an input sensor for sensing tokens delivered to the slot machine. A processor is connected to the input sensor for receiving information about tokens entered into the machine and for initiating a corresponding cycle of the slot machine. A first pseudo random number generator is connected to the processor for being triggered upon sensing a token input. A background position control unit is connected to the first pseudo random number generator for associating a plurality of position pointer addresses to the signal from the first pseudo random number generator. A background reel memory includes a plurality of background reel memory sections, with each background reel memory section coordinated to a corresponding one of the plurality of position pointer addresses and connected to the processor for delivering to the processor the final configuration of this cycle. Each background reel section determines coded symbol signal values of a plurality of main display symbols with each of the main display symbols to be displayed in the center of a display zone. An output control is connected to the processor for delivering a winning payout amount in case a winning combination was delivered by the plurality of position pointer addresses of the background reel sections. A video reel memory is connected to the background reel memory for determining coded symbol signal values of subsidiary display symbols to be associated with each of the main display symbol.
