ABSTRACT:
A block puzzle consisting of three blocks, one being characteristically "O"-shaped and the other two each being characteristically "C"-shaped, is described. The blocks are slidably engageable into a mutually perpendicular interlocking arrangement in which each block passes through the other two blocks substantially concealing the "O"-shape of the one block and the "C"-shape of the other two blocks. In various embodiments, the central openings in the blocks are respectively rectangular, oval and hexagonal in shape.
