Sudoku Daily: Logic Puzzle

Sudoku Daily is classic 9x9 sudoku, built to be played every day.

A NEW PUZZLE EVERY DAY
Everyone gets the same daily challenge, so you can compare how you did.

FOUR DIFFICULTIES
Easy, Medium, Hard and Expert. Difficulty is measured by the solving techniques a puzzle actually requires, not by how many numbers are missing, so a level always feels the way it should.

HINTS THAT TEACH
Stuck? A hint points at the cell and explains why that number belongs there, so you finish the puzzle knowing something you did not know before.

BUILT FOR COMFORTABLE PLAY
- Pencil marks with automatic clean-up as you solve
- Undo, erase, and mistake tracking
- Row, column and box highlighting
- Light and dark themes
- Your game is saved automatically, so you can stop mid-puzzle

FREE AND OFFLINE
No account, no sign-up, and no internet needed to play. Puzzles are generated on your device, so you will never run out.

Ads keep the app free. Watch one if you want an extra hint, another chance after running out of mistakes, or an hour with no ads at all.
