# Replay every move

Signed-in players can now undo and redo their current moves, then revisit every step after finishing a game.

Your Sudoku history now tells the whole story:

- **Undo and redo while playing:** Signed-in players can step backward or forward through answers and notes without losing their place.
- **Replay finished games:** Open any completed game and move through it from the empty grid to the final answer.
- **Scrub through the timeline:** Use the replay slider or the previous and next controls to jump to any move.
- **Keep history across devices:** Move history is saved with the game, so it remains available after signing in again.
