&times;<br>Move notation

Moves use Singmaster notation , devised by mathematician David Singmaster and now the basis for the official WCA standard. Each letter is a 90&deg; clockwise turn of one face, judged while looking directly at that face.

LetterFace<br>R / LRight / Left<br>U / DUp / Down<br>F / BFront / Back

Add a modifier after the letter:

SuffixMeaning<br>(none)Clockwise quarter turn (e.g. R)<br>'Counter-clockwise quarter turn, "prime" (e.g. R')<br>2Half turn, 180&deg; (e.g. R2)

Beyond the six faces, this visualizer also supports the rest of the standard:

TypeMovesTurns<br>SlicesM E SThe middle layer (M follows L, E follows D, S follows F)<br>Wider u f l d b<br>or Rw Uw…The face plus its adjacent slice<br>Rotationsx y zThe whole cube (x like R, y like U, z like F)

A random Scramble is handed to a real two-phase solver (Herbert Kociemba&rsquo;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.

Your cube, in 3D and unfolded. Spin the cube (hover to pause) to compare it with the real one, then tap any sticker — centers included — to cycle its color until they match.

Every cube unfolds into this flat map — each of its 6 sides becomes one square. That's the layout you're checking below.

 Don't worry about getting a perfect color match — you can always tweak any sticker by hand before we unscramble it.
