Why the solver rejects some colorings
A real 3×3 cannot have a single flipped edge, one twisted corner, or only two swapped pieces. The validator checks color counts, cubie uniqueness, orientation balance and permutation parity before searching.

Rubik's Cube Solver
Match your 3×3 cube, catch impossible states before you waste a move, then get a local two-phase solution with step-by-step playback. Manual entry, scramble notation, and camera-assisted color capture all stay in one clean workspace.

LIVE CUBE

MANUAL ENTRY
Tap stickers to match your cube
Centers are locked. Hold the physical cube with white up and green front to match this standard orientation.
MOVE NOTATION
Already have the scramble?
Standard U R F D L B notation, with ' for counter-clockwise and 2 for a half turn.
CAMERA-ASSISTED ENTRY
Capture six faces, then review
Start with U. Keep the face square to the guide.
Each captured center becomes that face's color calibration, so different cube shades and lighting are handled locally. Review orientation before solving; manual paint is always available for corrections.

PRACTICE MODE
Turn the virtual cube yourself
Use face buttons or your keyboard. This is intentionally secondary to the solver, but it lets you rehearse notation without another page.

Notation, scan tips & solver scope
Two-phase solving
The local search first moves the cube into a restricted subgroup, then finishes the permutation. Pruning tables guide both phases so ordinary scrambles solve quickly without uploading your state.
Camera capture
Scan all six faces under even light. The six center samples calibrate the classifier to your actual plastic colors. If one sticker is misread, correct just that sticker in Paint Cube rather than rescanning everything.
What this does not promise
The solver targets 22 moves or fewer in half-turn metric, not a proof of the absolute shortest solution. For physical speedsolving, CFOP/Roux technique and finger tricks are a separate skill.
