Why play the Daily Sudoku?
The Daily Challenge gives you a single shared puzzle to compete against - and to compete against yourself. Because everyone plays the exact same board, it is the fairest way to benchmark your solving time. A short, focused mental workout that fits into any part of the day, with no sign-up and no ads on the grid.
Tips for faster daily times
- Scan the most-populated 3×3 boxes first - they usually reveal an immediate forced placement.
- For each digit 1–9, check rows and columns where it already appears in multiple units.
- Hunt hidden singles: a digit that can only fit one cell in a row, column, or box.
- The daily uses easy difficulty, so pencil marks are rarely needed - trust quick scanning.
- If you get stuck, move to another area and return later. A single new digit often unlocks a chain of forced moves.
