Rubika kubs Rubiks Master Cube 4x4

The Rubik's Cube 4x4 (also known as the Revenge or the Master Cube) is a 4x4x4 version of the Rubik's Cube. Unlike the original Rubik’s Cube 3x3 (and the Rubik’s Cube 5x5), it has no fixed facets: the centre facets (four per face) are free to move to different positions. The 4x4 is slick, fast and robust due to the tough tiles and the smooth mechanism we are using. This Rubik's 4x4 is no more difficult to solve than the original 3x3 cube but requires different techniques.
