Designed by Wayne Daniel, Tetrahedra puzzles involve many combinations of different numbers and shapes of pieces.
Individual pieces contain sequences of alternating units of tetrahedra and square based pyramids.
There is a challenge to disassembling the puzzles with four or more pieces as they stay together even when shook. A great intoduction to our Tetrahedron line. See it on our Polyhedra page. Please contact us to order.
