Notation
Understand the letters R, U, F… that describe every move.
Each face of the cube has a letter. This notation is the same all over the world:
- R (Right): the right face
- L (Left): the left face
- U (Up): the top face
- D (Down): the bottom face
- F (Front): the front face, the one facing you
- B (Back): the back face
A letter on its own means: turn that face a quarter turn clockwise. An apostrophe (R’, read “R prime”) means a quarter turn counter-clockwise. A 2 (R2) means a half turn.
A sequence like R U R' U' is called an algorithm: do the moves one by one, from left to right. Pick a move, then press play to see it.
R
Right face: a quarter turn clockwise.
The 3D cube could not be loaded.
Tips
- To know which way to turn, imagine looking straight at that face: clockwise means like the hands of a clock.
- Always keep yellow on top. You may turn the whole cube (keeping yellow on top) to bring the piece you are working on to the front.
