Abstract
Abstract The present invention is directed to a puzzle having nine virtually identical interconnected members contained within a casing. The members are interconnected through toothed gears which are accessible from the exterior of the casing. Each of the nine members and the top surface of the casing has colored dots arranged in an array. To solve the puzzle matching pairs of dots must be aligned with each other and with the dots arranged around the periphery of the surface of the puzzle. The puzzle is both challenging and entertaining and will provide the user with hours of entertainment.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
161 words
A puzzle comprising a casing having a transparent upper wall; a plurality of members each rotatably mounted in said casing, said members comprising an upper spool and a lower spool coupled concentrically such that said lower spool can rotate independently of said upper spool; each of said members also comprising intermeshing means which allow each of said members to contact adjacent members and being positioned such that rotation of one of said members is communicated to the remainder of said members such that all of said members rotate in association with one another; each of said members including a like number of indicia located thereon in an array around the periphery of said members; a plurality of indicia associated with each of said members located about the periphery of the upper wall of the casing at spaced intervals; and a means to lock any one of the upper spools in a fixed position while allowing rotation of its associated lower spool.
