Samurai Sudoku Solver: Scan

Scan a Classic or Samurai grid

$2.99 · Designed for iPad. Not verified for macOS.

Stuck on a Samurai? Point your camera at a printed Sudoku — Classic or the five-grid Samurai — and get the answer in a second. No ads, no subscription, nothing uploaded. The only scanner that solves a Samurai. Point your camera at a printed Sudoku and get the solution. Not just the standard 9×9 — Scan & Solve reads the five-grid Samurai too, the one no other scanner will touch. HOW IT WORKS Hold your phone over the puzzle. It finds the grid, reads the digits, and works out the answer — usually in about a second. Nothing to type in, nothing to line up. IT TELLS YOU HOW, NOT JUST WHAT Every solution names the techniques the puzzle actually needed — naked singles, hidden pairs, X-Wings — so you can see where you were stuck. Want to work through it properly? One tap opens the exact board in Samuraiku and walks you through it step by step. SHARE THE ANSWER Send or print a clean solution card with the original clues in bold, so you can check your own work against it. WHAT IT DOESN'T DO No ads. No subscription. No account. Nothing is uploaded — the camera image never leaves your phone, and it's never saved to your photo library. You pay once. Classic 9×9 and Samurai. Works offline. Made by the people behind Samuraiku.
