Gear Cube Cube. Three 3x3 cubes are very similar to the original: the Gear Cube Extreme, the Gear Cube Ultimate, and the Even Less Gears Cube. Gear Cube Extreme: Unlike the original Gear Cube with 12 total gears, the Gear Cube Extreme (also known as the Anisotropic Cube) has only eight gears. The top and bottom rows remain gear cogs, whereas the middle layer edge cogs have been removed. Taking away the middle layer cogs and replacing them with standard edges allows for different movement between rows. Due to the added straight edges, the cube can now make 90° turns on two
Floppy Cube (20), the Rubik's Domino (18) and, to some extent, the Pocket Cube (11). The table also shows that there is only one combination that is exactly 8 moves away from the solved state; this is the combination in which all the corners are in their correct places but all the edges are flipped, analogous to the "superflip" on the Rubik's Cube, which requires 20 moves to solve. The Super Floppy Cube (often shortened to "Super Floppy") is a common variant of the Floppy Cube. It was also invented by Katsuhiko Okamoto but several versions have also been produced by other
