OpenSudoku

Fun and well written This is a good Sudoku game, with great interface and no bugs. I only wish that it would sort the puzzles so that unsolved always go to the top.

Old but gold. Definitely the best sudoku app on the market. Simple and non off those weird colors and hint features. I wish there is a check button that tells you what number position is incorrect (which by pressing adds more time solved) but seeing as this app haven't been updated for awhile I hope someone else makes a new one :)

Love it When I complete them all.... I restart all over again.

Outstanding Clean and simple. Very nice!

Awesome + open source It's great but Would love to see a ui more fitting to the holo design.

Superb Simple and fast Wonderful app and OSS too

Excellent game This is by far the best Sudoku I found on the market. A random Sudoku generator would be a great addon.

Excelente juego de sudoku y es open source

Good game and no ads! Thank you for making such a good game that works perfectly on my Nexus 10 and has no ads or crazy permissions.

Over two years later and still the best Best Sudoku game on Android. Unlimited fun, would love to see different styles of sudoku available to play. For those who complain about difficulty, have you downloaded the additional difficulties?
