How it works

Scan it.

Point the camera at each face — a guided flow walks you around all six. Wurfel reads the colors so you don’t have to.

Prefer typing it in? Tap colors onto a 3D cube instead.

Solve it.

A complete solution in seconds, computed right on your phone. Watch every move play out on the cube — smooth, in 3D, impossible to lose.

Play it through, or step forward and back at your pace.

Learn it.

Every move comes in plain language — “turn the right face clockwise” — next to its notation. Do it enough times and you won’t need us anymore.

That’s the plan, anyway.
