Classic sudoku, done right
Clean, offline sudoku. Five difficulties, a daily challenge, and no clutter.
About Sudoku
Sudoku with everything that matters and nothing that doesn't: a clean board, five real difficulty levels, and a fresh puzzle every day.
Every puzzle is generated with exactly one solution and verified before you see it, so a careful solve always gets you home — you will never have to guess.
Pencil notes, unlimited undo, two free hints and an optional mistake limit are all there when you want them, and all switchable off when you would rather solve unaided.
Free to play, supported by ads. Extra hints are available by watching a short video if you want them — never required to finish a puzzle.
