ABSTRACT:
An educational question-and-answer game provided with answer verifying capabilities, a code member having a plurality of alignment possibilities, and a number of answer switches movable relative to a supporting member. A number of question-carrying elements, in the form of cards, transparencies or the like, cooperate with the code member and answer switches in such a manner that verification is accomplished only when all questions on the question-carrying element are answered correctly. The code and supporting members are each provided with part of an indicating device, and can be brought into various relative positions which are differently designated by the indicating device, in such a way that the answer switches are differently associated with the code member in each of the said positions. Each answer switch can be moved into at least two positions in order to answer any one of the questions asked, and can be brought into registry with the appropriate longitudinal unit of code alignment. The answer verifying capability can be multiplied in its verifying capacity, which results from the number of different positions of the code member relative to the supporting member or the longitudinal units of code alignment, and for improving the enciphering of the possible verifications.
