Krystian's Twist is an idea by Krystian Wilisowski, which he posted at the Twisty Puzzles Forum. Krystian worked out how to turn a tridiminished icosahedron into a jumbling twisty puzzle. Actually, his version was more complex with four slices. Carl Hoff suggested that even the jumbling three-slice puzzle could be interesting. By playing this puzzle, Oskar discovered that the puzzle has a very nice 7-step jumbling-move sequence.
