The Rubik's Cube is a 3-D mechanical puzzle invented
in 1974[1] by Hungarian sculptor and professor of
architecture Erno Rubik. In a classic Rubik's Cube,

among six solid colours (traditionally white, red,
blue, orange, green, and yellow).
There are six central pieces which show one coloured
face, twelve edge pieces which show two coloured
faces, and eight corner pieces which show three
coloured faces. Each piece shows a unique colour

the solved Cube, there is no edge piece with both red
and orange sides). The location of these cubes

outer third of the Cube 90°, 180° or 270°, but the
location of the coloured sides relative to one another
in the completed state of the puzzle cannot be
altered: it is fixed by the relative positions of the
centre squares. However, Cubes with alternative colour
