Abstract
An electronic circuit contained within a housing and having two sets of optoelectronic display elements on the face of the housing arranged to represent the spots of a set of dice. The electronic circuit includes a timer which produces timing pulses of varying duration controlled by an externally available switch which determines the beginning of the timing pulse and their duration. During the duration of each timing pulses a switching circuit produces two varying sequences of clock pulses each of which is counted by a binary counter configurated to six counts in a repetitive counting cycle. At the termination of each timing pulse, the final count on each of the counters is displayed on the optoelectronic elements as the numbers on a set of dice. An audible oscillator simulates the sound of rolling dice during the course of each timing pulse. The electronic circuit uses integrated circuits and is designed to utilize a minimum number of circuit chips, and specifically three and two thirds circuit chips for a set of dice.
