The daily puzzle: a shared sudoku challenge, every day
The daily puzzle offers a single sudoku 9×9 grid to every player, changed each day at midnight. The rules stay the same as classic sudoku: fill every row, every column, and every 3×3 box with the numbers 1 to 9, without repeats. Click 📅 Today to load today's challenge, or New to go back to a random grid at any time.
Since everyone solves the same grid on the same day, it's a great chance to compare your times with friends and family. Your stats (games, wins, streak, best times) are actually shared with the classic 9×9 Sudoku page.
Why play the daily puzzle?

- Comparable between players — everyone solves the same grid, so times can be compared.
- Easy to share — the "Share result" button copies a ready-to-send text to your friends.
- Streak tracking — the "Streak" stat counts your consecutive wins.
