Meffert's Gear Cube Extreme

Object: Mix up and put back to start The Gear Cube Extreme is made with a black ABS plastic body. The Idea of this puzzle is to scramble all of the colors and then organize them backmto the start position. This cube has gears throughout its mechanism which causes edge pieces to rotate out of their normal square position, unlike the original Gear Cube, this puzzle has four pieces that are non-geared, which allow two of the six faces to turn at a 90° angle, as opposed to the other four faces that rotate at an 180° angle. The designer of Gear Cube Extreme, Oskar van Deventer from Leidschendam in the Netherlands, started designing puzzles when he was 12, and has now been designing for over 30 years. Oskar originally designed the four non gear edges independently, so that one could convert their Gear Cube into the Extreme version, which he called the Anisotropic Cube. The Gear Cube Extreme is now manufactured by Meffert’s Rotations Puzzles. Uwe Meffert, born in Wernigerode, Germany, not only manufactures the puzzles, but has designed many of his own puzzles as well.
