About Sudoku (doce.games)

This daily sudoku comes with its level printed on it. Puzzles are numbered from #1 on 30 August 2026, and the difficulty follows the weekday: easy on Monday and Tuesday, medium on Wednesday, Thursday and Sunday, hard on Friday and Saturday. The site builds each level from the solving techniques it allows, rather than labelling a random grid.

You fill the grid with the on-screen keypad and can switch to notes for pencil marks. The clock is your score. A number that contradicts the solution is not blocked: it is marked and adds a 15-second penalty, so trial and error is possible but never free. When you finish you can share your time or send a challenge link to a friend.

It is one of the daily games on doce.games, a small site with no accounts, no ads and nothing to install, playable in Spanish, English, German, Portuguese, Italian and French. The daily games there share the same rules of the house: one try a day, the same puzzle for everyone, and a link to challenge a friend with your result.

It suits sudoku players who like knowing how hard the day will be before they start, and anyone who wants a timed grid without ads.

1. Open doce.games/en/sudoku and check the day's level.
2. Tap an empty square, then a number on the keypad.

5. Finish the grid and share your time or challenge a friend.

Tips

• Plan around the weekday: Monday and Tuesday are quick, Friday and Saturday need pairs and pointing techniques.
• Use notes on the hard days rather than guessing; every wrong number costs 15 seconds.
• Clearing notes is automatic when you place a number, so keep marks up to date as you go.
