Krystian’s Cube

Krystian’s Cube was proposed by Krystian Wilisowski. The puzzle turns like a 2x2x2 Rubik’s Cube.
However, when a 45-degrees turn is made, a new move is enabled that mixes pieces at the edges.
This makes the puzzle into a new type of “quasi-doctrinaire” twisty puzzle.

Proportional Oh

Proportional Oh was suggested by David Tzur. It looks like a 3x3x3 Rubik’s Cube, but those turns do not work. Instead the corners need to be turned. Surprise: oh! Hence the puzzle’s name.
