Tips for Sudoku
- Scan for a digit that can only go in one place in a box first.
- Do not guess a full row early — it is how boards lock up.
- Play a second round right after the first — you will notice patterns you missed the first time.
- If you get stuck, restart the round instead of leaving the page: a fresh board often makes the next move obvious.
