Hi Shapeways fans, Diskussion is a magnetic sequential-movement puzzle. The tokens are 12x3-millimeter magnetic disks. There are also five magnets embedded in the frame. When one of the four rotors is turned such that the void goes over an embedded magnet, then the adjacent magnetic token will jump into the void. So the puzzle is played by only turning the rotors without touching the tokens. The one-way jumps of the tokens make it impossible to simply "undo" a wrong move. Nevertheless, the puzzle is relatively easy to solve. Watch the YouTube video. Buy the puzzle at my Shapeways Shop. Read more at the Twisty Puzzles Forum. Check out the photos below. Enjoy! Oskar
