Rubik's Cube

Rubik's Cube is a mechanical puzzle invented in 1974 by the Hungarian sculptor and professor of architecture Ernő Rubik. It is a plastic cube comprising 26 smaller cubes that rotate around a typically unseen kernel. Each of the nine visible facets on a side of the Rubik's Cube exhibits one of six colors. When the puzzle is solved, each side of the Rubik's Cube is a different color, but the rotation of each face allows the smaller cubes to be rearranged in many different ways. The challenge of the puzzle is to return the cube to its original state, in which each face of the cube consists of nine squares of a single color.
