495: Soma Cube

I can remember a block puzzle my maths teacher introduced to me, the “soma” puzzle was a lot like 3D Tetris.495SomaDev

There are 7 puzzle pieces, all variations of stacked cube clusters that fit together into a 3×3 cube when put together right.495Soma1

A fab fold, a simple series of box pleat collapses and a variety of techniques make these fairly robust puzzle pieces.495Soma2

I found a couple of ways to put them together, my students found many more, but Wikipedia says there are over 100 ways – wow.
