Daily Killer Sudoku fixes both the sudoku solution and cage arrangement to today’s date. Retry the same arithmetic constraints all day or compare with another player.
Same killer rules as the standard mode — cages sum correctly, no repeats in a cage, full sudoku uniqueness.
How to play Daily Killer Sudoku
- Killer sudoku rules with a date-seeded cage layout.
- Refreshing does not change today’s puzzle until the calendar date changes.
- New game reloads today’s daily grid, not a random one.
Strategy tips
- On a daily killer, write down which two-cell cages you solved first — tomorrow’s puzzle will feel faster with the same habit.
- Cross-reference cage sums with box boundaries; cages often straddle box edges deliberately.
- Daily mode rewards methodical cage order over random scanning.
- Use regular Killer Sudoku for unlimited random cage sets.
- Pair with Daily Sudoku for a numbers double without killer cages.
