This is a puzzle originally presented in Tokyo, 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).

This cipher device works three ways. In the initial position, it can translate from "Standard Galactic" an alphabet used in several video games including Minecraft. Spin the inner wheel and now you have a random substitution cipher. Finally, use the spinner to further randomize secret messages.

This Cube puzzle is composed of 10 pieces each of a different size. This design was inspired by a concept by Jean Carl. I am offering it in two forms. The only difference is that the smallest and opening piece is either one unit or two. This is the two unit version. In this version the pieces run continuously from two to eleven units. totaling 65 units.

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!
