Sudoku Lens: Solver & Scanner

Stuck on a sudoku and can't find that one last number? Sudoku Lens is the sudoku solver and scanner that finishes any puzzle for you in seconds. Take or choose a clear photo of a sudoku — from a newspaper, a book, a screen or a printout — and get the complete solution in seconds. No typing, no guessing, no frustration.

We made Sudoku Lens for everyone who loves sudoku puzzles: beginners who are still learning the rules, casual players who got stuck on the bus, and hardcore solvers who want to test their logic on the toughest grids out there.

★ SOLVE ANY SUDOKU FROM A CLEAR PHOTO
Take a clear photo and let the app do the hard part. Our smart sudoku scanner uses OCR to read the grid automatically — recognizing the printed numbers — and solves it for you. Already have a screenshot? Just pick a photo straight from your gallery and Sudoku Lens handles the rest.

★ SOLVES EVERY GRID SIZE
Most sudoku apps only deal with the classic 9x9. Sudoku Lens solves them all: tiny 4x4 and 6x6 mini-sudoku that are perfect for kids and quick breaks, the classic 9x9 puzzle everyone loves, and the seriously challenging 12x12 and 16x16 mega-grids for true experts. One app, every sudoku variant.

★ STEP-BY-STEP SOLUTIONS THAT ACTUALLY TEACH YOU
Don't just reveal the answer — understand it. Sudoku Lens walks you through the solution cell by cell, showing the logic behind each move. It's like having a patient sudoku tutor in your pocket, perfect for sharpening your skills and picking up new solving techniques.

★ PREFER TO TYPE IT IN? GO AHEAD
No photo handy? Enter the numbers by hand on a clean, adaptive keypad that reshapes itself to fit the grid size. Ideal for puzzles you copy from a friend, invent yourself, or just want to double-check.

★ FAST, BEAUTIFUL AND DISTRACTION-FREE
Enjoy 5 gorgeous color themes in both light and dark mode, buttery-smooth animations and satisfying haptic feedback. The interface is clean, modern and built to get out of your way so you can focus on the puzzle, not the menus.

★ WORKS COMPLETELY OFFLINE
No internet? No problem. Sudoku Lens solves every puzzle right on your device — on the train, on a plane, anywhere at all. Your puzzles stay private and the solver is always lightning fast.
