Libre-Sudoku is a Sudoku app for Android, built with Jetpack Compose and Material3.
Features:
- Basic things such as pencil marks (notes), undo, game pause, board reset and give up (show solution)
- 9x9, 6x6 and 12x12 with 4 difficulties
- Zoom and pan the board in 12x12
- 2 input methods. Digit first and cell first
- 2 types of mistakes checking. First is detecting game rules violations and the second is checking with final solution
- Statistics and records. Best and average times, win streak, started/completed games count and win rate
- Saves. You can continue any uncompleted game whenever you want
- Many settings and customizations such as auto erase notes, remaining uses, identical numbers highlight, app themes and more
- Tutorials for game techniques (in progress)
- Custom sudoku (manually or from string). Supported game types: 9x9, 6x6, 12x12
Hint: This app is available in both, F-Droid Main and IzzyOnDroid repos. For details on this, please see here.
While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
