Tips for Tackling Tough Grids
- Scan rows, columns, and blocks for numbers that appear frequently. This can often reveal strong candidates for remaining cells.
- Look for 'singles' – cells where only one possible number can fit based on the current grid.
- Don't guess. If you're stuck, revisit your advanced strategies or take a brief moment away from the puzzle.
- Use the pencil mark feature (if available) to note down potential candidates for cells. This aids visualization of patterns.
- Identify double or triple candidates within a row, column, or block. This information can help eliminate those numbers from other cells.
