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) |
A random Scramble is handed to a real two-phase solver (Herbert Kociemba’s algorithm), so the Solution you watch is a genuine, near-optimal solve — not the scramble played in reverse.
Tip: paste any algorithm into the Custom scramble box to watch it rewind move-by-move. Half turns are animated as two quarter turns.

A plain letter is a quarter-turn clockwise, judged while looking straight at that face. x y z rotate the whole cube.
Mirror each move on your real cube, then tap Next move.
