This is a puzzle originally presented in 2001. Its name is derived from the fan-blade-like shape of the pieces. All the pieces are the same shape with a different arrangement of textures on the outer faces.
The goal is to assemble a cube with all six sides as solid textures (two solutions) or to assemble a it with no quadrant adjacent to a matching texture, diagonals excluded (one solution).

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!
