JumbleStar is based on the geometry of a pentagonal prism. It has ten axes of rotation, one at each vertex of the shape. Each axis can be rotated to any of four stops, and then turns can be made on other axes providing they are not blocked. Every move is a jumbling move.
Other Items Needed:
Dye: If you want the puzzle to be black, you can save money by dyeing the pieces yourself with a nylon dye such as RIT or Dylon. Or Shapeways can dye the parts for you at an additional cost.
Stickers: Template available in the instructions forum. If you want professionally cut stickers, I recommend Oliver’s Stickers.
Screws: Ten 12mm M3 pan head screws and two 6mm M3 pan head screws are required, available in hardware stores or on the web.
Springs: Ten springs are needed, available in web puzzle shops. I get mine from HK Now Store.
Degree of Difficulty:
Assembly: Easy assembly.
Solving: Moderately easy for a jumbling puzzle.
JumbleStar turns very easily, and the mechanism is very stable.
