ABSTRACT:
A puzzle is comprised of cubically shaped pieces having 5 square holes centered on 5 of the cube faces and 1 square protrusion on the center of the sixth face. The protrusion is fitted with a spring loaded cog or catch so that the protrusion may be inserted into a square hole of another piece and will lock in place. The locked piece may be released only by inserting another piece in the correct orientation in another square hole in the same piece the first piece was inserted in. The release is effected by pressing the secondly inserted piece in all the way thereby releasing the catch of the first inserted piece but not allowing the release of the catch of the secondly inserted piece.
