Sudoku

Sudoku to play in your browser on a phone, tablet or computer: fill the nine-by-nine grid so that every row, every column and every three-by-three box holds the digits 1 to 9 once each. Six levels, from a 6×6 grid for beginners through easy and expert to master, every puzzle with exactly one solution and graded by the techniques it needs. Pencil marks (filled in for you if you like), undo, hints, an optional mistake check and mistake limit, large digits and a night theme, and a daily puzzle that everyone gets the same day.
