Tip of the Day
- Focus on the sub-grids first. Finding all instances of one number in a 3×3 block can clear mental clutter.
- Scan for cells where only one digit fits. Filling those anchors often unlocks a row or column.
- Use pencil marks sparingly—update them after each placement so candidates stay honest.
- When stuck, pick one digit and scan all rows for where it can still go in each band.
- A hidden single lives where a digit can only sit in one cell within a row, column, or box—even if that cell has other candidates.
- Pause for one slow breath before the next move. Accuracy beats speed on daily puzzles.
