Circuit for use in electronic game of nim

Claim 1

A circuit for use in an electronic game of nim, said circuit comprising a source of electrical energy; an AND gate having a first input, a second input and an output; first biasing means connected to the first input and including the source of electrical energy for biasing said first input at an ON level; a player operable switch connected to the second input for biasing the second input to an ON level when the switch is closed, thereby switching the AND gate to its conductive condition; a feedback network connected between the output and the second input for biasing the second input at an ON level when the output is biased at an ON level; a light source; and second biasing means connected to the second input, for normally biasing said second input at an OFF level whereby said AND gate is normally in its low output condition, said second biasing means including the source of electrical energy, and switching means connected between the light source and the AND gate, said switching means energizing said light source when said AND gate is in its high output condition.
