Cube Moves
An original 3×3×3 Rubik's Cube consists of 6 faces, each with 9 colored squares called facets, for a total of 54 facets. A solved cube has all of the facets on each face having the same color.
A cube move rotates one of the 6 faces 90°, 180° or -90° (half move metric). A center facet rotates about its axis but otherwise stays in the same position.
Cube moves are described with the Singmaster notation:
| Basic 90° | 180° | -90° |
| turns the front clockwise | turns the front clockwise twice | turns the front counter-clockwise |
| turns the back clockwise | turns the back clockwise twice | turns the back counter-clockwise |
| turns the top clockwise | turns the top clockwise twice | turns the top counter-clockwise |
| turns the bottom clockwise | turns the bottom clockwise twice | turns the bottom counter-clockwise |
| turns the left face clockwise | turns the left face clockwise twice | turns the left face counter-clockwise |
| turns the right face clockwise | turns the right face clockwise twice | turns the right face counter-clockwise |
The empty move is . The concatenation of is the same as, and is the same as .
