Tips for Today's Puzzle
- Scan for singles first. Before reaching for pencil marks, look for rows, columns, or boxes where only one number is missing. These quick wins build momentum and reveal hidden constraints elsewhere on the board.
- Use pencil marks strategically. On a hard puzzle, candidates narrow down quickly once you eliminate possibilities box by box. Focus on cells with only two or three candidates and look for naked pairs or pointing pairs.
- Take a break if you get stuck. Stepping away for even a minute can help your brain spot patterns you missed. The daily puzzle is available all day, so there is no rush.
