Getting the Most Out of Undo

Save your one-move rewind for the moments that matter most.

Undo rewinds your most recent move. It's especially useful when you accidentally press the corner-breaking direction, or when a new tile spawns in a bad spot and wrecks your layout.

That said, relying on undo too heavily won't help you improve. Ask yourself "is this really the best move?" first, and save the rewind for the truly tough calls.

In the late-game endgame, a single mistake can be fatal, so try out a move you're unsure of and undo it if the result turns out badly.
