A scrambled cube, solved with style.
Moves use Singmaster notation, devised by mathematician David Singmaster and now the basis for the official WCA standard. Each letter is a 90° clockwise turn of one face, judged while looking directly at that face.
| Letter | Face |
|---|---|
R / L | Right / Left |
U / D | Up / Down |
F / B | Front / Back |
Add a modifier after the letter:
| Suffix | Meaning |
|---|---|
| (none) | Clockwise quarter turn (e.g. R) |
' | Counter-clockwise quarter turn, "prime" (e.g. R') |
2 | Half turn, 180° (e.g. R2) |
Beyond the six faces, this visualizer also supports the rest of the standard:
| Type | Moves | Turns |
|---|---|---|
| Slices | M E S | The middle layer (M follows L, E follows D, S follows F) |
| Wide | r u f l d bor Rw Uw… | The face plus its adjacent slice |
| Rotations | x y z | The whole cube (x like R, y like U, z like F) |
Because every quarter turn has an inverse (R undoes R'), a Scramble applied to a solved cube can always be undone: the Solution is that same sequence reversed with each move inverted.
Tip: paste any algorithm into the Custom scramble box to replay it. Half turns are animated as two quarter turns.

R L U D F B, slices M E S, wide turns r u f (or Rw), or rotations x y z. Add ' for counter-clockwise or 2 for a half turn, e.g. R U R' U2 f x'.
