RotoPrism 3 (round) is a bandaged puzzle with three axes of rotation, based on the geometry of the triangular dipyramid. It is essentially a shape modification of my Fracture-6 puzzle. The three axes are located at the center of each face around the equator of the puzzle. Every axis is capable of turning in 90 degree increments, but only when there are no triangular pieces on that face, otherwise the axis will be limited to 180 degree turns. This bandaging makes RotoPrism 3 difficult to solve.

Other Items Needed:

Dye: I recommend buying the puzzle in black from i.materialise. They do a fantastic job for very little extra cost.

Stickers: Please contact me for the sticker template. If you want professionally cut stickers, I recommend Oliver’s Stickers or Chewie's Custom Stickers.

Screws: Three 12mm M3 pan head screws required, available in hardware stores or on the web.

Springs: Three springs needed, available in web puzzle shops. I get mine from HK Now Store.

Degree of Difficulty:

Assembly: Moderately easy assembly.

Solving: Moderately difficult to solve.


RotoPrism 3 (round) turns easily, and the mechanism is stable.

Have fun!

Welcome! My goal when designing puzzles is to create geometries that are visually striking and have a complexity belied by their apparent simplicity. Many of my puzzles use odd axis systems, and exhibit strange properties such as jumbling and shape-shifting. Enjoy!
