Game overview
This app generates unlimited free Sudoku puzzles of three different difficulties.
If you'd like, you can also enter your own (or your newspaper's!) puzzles into the app and work on them there too, even getting hints or the full solution if you get stuck. You can also customize the appearance with multiple themes, and change the settings to toggle helpful features like highlighting your currently-selected row and column and warning you of any mistakes.
