Fracture-10 won a jury honorable mention award at the 2011 International Puzzle Party Nob Yoshigahara Puzzle Design Competition.
The Fracture-10 puzzle is a ten sided solid with five axes of rotation. Each vertex around the equator of the puzzle can be turned in 90 degree increments, although due to blocking that frequently occurs, rotations are often limited to 180 degrees. Don't be fooled by the simple design of this puzzle, it is fiendishly difficult. It's a good thing that it looks just as nice (if not better) scrambled as it does solved!
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 & Springs: The puzzle snaps together, so no screws or springs are needed.
Degree of Difficulty:
Assembly: Easy assembly. I have also made an assembly video so that you can see exactly how to put the puzzle together.
Solving: Very difficult to solve.
Fracture-10 has a robust mechanism that does not pop apart, and turns easily.
