Abstract: Puzzle apparatus having a square playing area defined by a square pivot frame each side of which carries a plurality of strip members pivotally mounted for movement against said area in overlying relationship and interleaved with one another to provide a preselected solution sequence. The strip members have spaced recesses along their respective lengths providing lateral and endwise legs defining a plurality of L-shaped contiguous portions each having three discrete identifiable sub-areas thereby providing a multiplicity of selectable puzzle solutions.
