Celebrating 40 years of the Rubik’s Cube.

Rubik’s Cube is a 3-D combination puzzle invented in 1974 by Hungarian sculptor and professorof architecture Ernő Rubik. In a classic Rubik’s Cube, each of the six faces is covered by nine stickers, each of one of six solid colours (white, red, blue, orange, green, and yellow; in currently sold models, white is opposite yellow, blue is opposite green, and orange is opposite red, and the red, white and blue are arranged in that order in a clockwise arrangement). An internal pivot mechanism enables each face to turn independently, thus mixing up the colours. For the puzzle to be solved, each face must be returned to consisting of one colour. Similar puzzles have now been produced with various numbers of sides, dimensions, and stickers, not all of them by Rubik -Source:  Rubik’s Cube
