Claim 1
Independent Claim
199 words
In a game board assembly for receiving questions to be answered and signifying selection of a correct answer to a question, the combination comprising: a. a main base member; b. means on said main base member forming a multiplicity of normally electrically nonconductive cross points each correlated to the correct answer to a different question received in said game board assembly; c. electrical contact assembly means supported on the main base member and including a multiplicity of normally closed electrical contacts correlated to said multiplicity of normally electrically nonconductive cross points; d. question bearing control means selectively associated with said electrical contact assembly means and operative to retain some of said normally closed electrical contacts in open condition; e. means supported on said main base member having thereon indicia associated with said cross points and representing correct answers presented on said question bearing control means; f. means for making an electrical circuit through one of said normally electrically nonconductive cross points by selection of an indicia associated therewith representing the correct answer to a question presented on said question bearing control means; and g. means responsive to making of said circuit signifying selection of indicia representing a correct answer.
