Ultimate Insanity is similar to my Edge of Insanity puzzle, but three additional axes have been created at the long edges of the trigonal dipyramid shape. The puzzle has a total of nine axes, one at every edge. Moves on these axes can be combined in any order. This makes the puzzle extremely complex as it jumbles and shape shifts constantly.
Other Items Needed:
Dye: If you want the puzzle to be black, you'll need to dye the pieces yourself with a nylon dye such as RIT or Dylon. This puzzle is only available in white because it is printed in a sinterbox to reduce the cost.
Stickers: Template available in the instructions forum. If you want professionally cut stickers, I recommend Oliver’s Stickers or Chewie's Custom Stickers.
Screws: Nine 12mm M3 pan head screws required, available in hardware stores or on the web.
Springs: Nine springs needed, available in web puzzle shops. I get mine from HK Now Store.
Degree of Difficulty:
Assembly: Inside-out core requires lots of dexterity and patience to assemble.
Solving: Extremely difficult to solve.
Ultimate Insanity turns easily, and the mechanism is stable, although it can pop if care is not taken to align slices before turning.
