About this game

Meet NumberLab — a fast, private, fully offline Sudoku companion. Point your camera at a puzzle in a book or newspaper and NumberLab reads the grid for you, then helps you solve it, learn from it, or just check your answer. No account, no sign-in, and no internet connection required.

Scan any Sudoku with your camera
Line the board up with the on-screen guide and NumberLab recognizes the printed digits on the spot, right on your device. Mis-read a number? Fix it in a tap on the review screen before you start.

Solve and check instantly
Get the complete solution for any valid puzzle, or confirm that the one you entered has a single correct answer.

Learn with step-by-step hints
Stuck on a square? NumberLab gives you the next logical step — not just the answer — so you can improve your own technique at your own pace.

Create your own puzzles
Generate fresh Sudoku at a range of difficulty levels whenever you want something new to play.

Keep your puzzles organized
Save the boards you scan or create, search and filter your collection, and come back to them anytime.

Private and offline by design
Everything runs on your device. Scanning, solving, and hints all work with no network connection, and your puzzles never leave your phone.

NumberLab is free to use. If you'd like to support development, you can choose to watch an optional ad — but every feature works fully whether you watch one or not.
