Abstract
Abstract An educational puzzle made up of a plurality of blocks or puzzle pieces having the shapes of a rhombus and forms generated by dividing the rhombus. Puzzles can be formed having, for example, a hexagonal shape utilizing various combinations of the pieces. A hexagonal container can hold a plurality of puzzles of varying complexity which can then be assembled within the container so that unless each puzzle is properly assembled, the last puzzle cannot be assembled.
