Claim 1
Independent Claim
251 words
A comparative answer educational and recreational device comprising: a generally flat board having a front portion and a back portion; a multiplicity of paired, normally unconnected question contacts disposed on the front of said board and extending therethrough; a multiplicity of answer contacts disposed on the front of said board and extending therethrough, each of said last mentioned contacts being connected to one contact of a matching set of paired question contacts; a common means connecting all of the unconnected contacts of the paired question contacts, said common connecting means passing through a correct answer indicating means and operatively connected to an electrical power source; a single answer selector probe operatively connected to said power source and being extensible to allow connection with all answer contacts; question card means disposed juxtaposed to said paired question contacts and having question indicia on the front side thereof and only a single conducting strip extending across the rear side for conductively connecting the contacts of one of said pair of question contacts; and answer indicia disposed adjacent said answer contacts whereby when the indicia on said question card and that adjacent said answer contacts are properly matched by connecting said probe to the answer contact adjacent the correct answer indicium, current will flow from said power source, through said selector probe, said answer contact, said matched paired question contact, said conductive area of said card, and said correct answer indicating means back to said power source to actuate and operate said last mentioned means.
