Yorkhouse Puzzles and Surprises

Shop Details
I am a long-time puzzle designer. This shop features puzzles I've designed or discovered over the last 30 years or so with a spotlight on the puzzle pieces of the Spiral Group I discovered in 1978. Mix and match 8 SG pieces at a time to make many cube puzzles.
I will also post several puzzles of as many different kinds as I can figure out. And surprises.

All puzzle and model designs presented here are mine unless otherwise noted.
I welcome comments, suggestions and requests!
