About This Game

Sudoku Deluxe serves the world's favorite number puzzle to every skill level at once. Beginners get easy grids built for fun, relaxation and pleasantly passing free time; advanced players get the demanding boards that make a pencil-and-brain session worthwhile. The interface stays minimal and quick, so switching difficulty to match your mood takes seconds, not menus. No timers punish slow thinking and no ads interrupt mid-deduction — this is sudoku as a daily habit rather than a test. Thousands of boards, one clean ruleset, playable instantly in your browser on phone or desktop. Free, forever, no download.

How to Play

Fill every row, column and 3x3 box with digits 1-9, each used exactly once per unit. Select a cell and place a digit; the interface flags conflicts so pure logic stays in charge. Beginners: hunt for the most complete row or box first and ask what must be true. Veterans: use candidate notation and hunting pairs. Difficulty is your dial — change it any time without losing progress. Tip: the fastest solvers spend more time reading the board than writing on it.
