ARQS Sudoku Logic Lab

A clear mind. One square at a time.

ARQS Sudoku Logic Lab — Offline Edition v1.1.0 gives you a clean, focused Sudoku game with fresh puzzles in three clue-density modes. Every generated puzzle is checked for a unique solution.

Use pencil notes, undo, candidate guidance, entry checking and explained hints. Pick a daily puzzle, pause whenever you need, and resume your locally saved game when browser storage is available. No account, in-game ads, cloud services or gameplay tracking.

One-time price: $19.99 USD. Includes the complete, self-contained HTML game, illustrated interface and quick-start guide. Extract the ZIP and open app.html in a modern desktop browser. The public browser demo is suitable for trying the controls on a phone; mobile file-viewer behavior varies, so the downloadable edition is intended primarily for desktop use.
