Turn a face — drag a sticker and the layer follows your finger; let go to lock in the nearest turn. A right-click (or a second finger) cancels and snaps it back.

Orbit the view — drag the empty background or right-click drag with a mouse; drag with two fingers on a touchscreen. Use the ← ↑ → ↓ arrows too.

Zoom / size — scroll the mouse wheel, or pinch with two fingers.

Goal — make every side a single colour. Your score is the number of quarter-turns used. Fewer is better.

Stuck? — hit Solve (or S) and the cube solves itself in close to the fewest possible moves.

Wrong turn? — Undo (or Z) reverses just your last move, and it won't count against your score.
