Sudoku

A clean Sudoku app with logic-based difficulty and helpful assists
A clean Sudoku app built with Flutter. Every puzzle is uniquely generated, and its difficulty is derived from the logical solving techniques required to complete it.

Features:

* Logic-based difficulty - difficulty is derived from the techniques needed to solve a puzzle (Hidden Single, Naked Pair, X-Wing, Swordfish, and more).
* In-game assists - notes/pencil marks, auto-notes, undo, conflict highlighting, and validation.
* Statistics & leaderboard - track your solve times per difficulty, with a top-10 board shown on the solved overlay.
* Resume - your current game is saved locally so you can continue right where you left off.
* Theming - light and dark modes plus custom color themes with a live preview.
* Responsive layout - adapts the control placement for phones and larger screens.

The app works fully offline, stores all data locally on your device.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
