About Rubik's Solver

Rubik's Solver is a free, independent set of 3D solvers for the twisty-puzzle family. You paint a model of the puzzle to match the one in your hands, press Solve!, and step through the answer move by move while turning the real thing.

Why it exists

Most solvers online cover the 3x3x3 cube and stop there. The puzzles that are genuinely hard to find help for — the Pyramorphix, the Skewb, the Rubik's Snake — either get no coverage at all or get a fixed recipe that works only from a particular starting position. This site covers six puzzles, and for the smaller ones it returns a provably shortest solution rather than a memorised sequence.

It is also built to be honest about the difference. The Rubik's Cube 3x3x3 uses a two-phase algorithm that finds short, near-optimal solutions rather than guaranteed-shortest ones, and every page that uses it says so.

How the solvers are verified

Each puzzle is modelled from one geometric source of truth: pieces are exact convex polytopes and every move is an integer rotation matrix, so a move sequence is either exactly valid or it fails outright. On top of that, each solver is checked against the puzzle's independently published mathematics by exhaustively enumerating its entire state space:

• Position count — the number of reachable states the search finds must equal the number published in the literature.
• God's number — the depth of the hardest position the search finds must equal the published diameter of the puzzle.
• Average solution length — the mean over every reachable state must match the published average.

These checks run as part of the test suite, not as a one-off. A solver whose enumeration disagrees with the published figures fails the build, which is why the shortest-solution claims on this site can be stated as facts rather than hopes.

What the site does not do

• It does not require an account to use any solver.
• It does not store the puzzle you painted; solving happens per request and nothing about your puzzle is kept afterwards.
• It does not load analytics or advertising until you have said yes. See the privacy policy for exactly what that means.
