A puzzle consisting of a cube with colored faces made of 26 smaller colored blocks attached to a spindle in the center, the object being to rotate the blocks until each face of the cube is a single color.
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.On early cubes, the position of the colours varied from cube to cube.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 have only one colour. Similar puzzles have now been produced with various numbers of sides, dimensions, and stickers, not all of them by Rubik.

A letter by itself means a 90 degree clockwise rotation of the face. A letter followed by an apostrophe is a counterclockwise turn. For example: F R’ U2 D means front face clockwise, right counterclockwise, a half turn of the upper face and then down clockwise.
