Sudoku 9x9

Sudoku 9x9 brings the classic number puzzle to your browser with a clean grid and three difficulty settings to choose from. The goal is straightforward — fill every row, column, and 3×3 box with digits from 1 to 9, no repeats allowed.

Beginners can start on easy mode to get a feel for the logic, while harder difficulties leave far fewer numbers pre-filled, demanding much more deduction and patience. A hint system is available if you get stuck, though leaning on it too heavily takes away from the satisfaction of solving a grid entirely on your own.

Sudoku rewards careful thinking over speed. Whether you have five minutes or an hour, a single puzzle can be as relaxed or as mentally demanding as you want it to be.
