Take apart the pieces and put together into a twinform shape.

This demanding puzzle was René Dawir’s exchange puzzle from the IPP30 (International Puzzle Party) hosted in Osaka & Hakone, Japan in August of 2010. The puzzle contains 6 pieces.  Each piece is made of 2 tetrahexes which can rotate around an axis.  The goal: Disassemble the twinform and then assemble the 6 pieces into the twinform shape as pictured on the insert.  A twinform is a shape with 2 identical layers (each layer must have the same shape). Additional twinforms can be assembled with 2 pieces (easy) to 6 pieces (difficult). Designed and made by: Marcel Gillen
