Doesn’t work, extremely confusing to use, wouldn’t recommend. Use a different app. -- Idiotic retards, 2025-08-01 ### *---- "Absolute garbage" This app is absolute garbage. It doesn’t work had every number programmed in correctly and it said no solution. App is junk -- Ace2566, 2022-06-26 ### *---- "App doesn’t even work" The scanner is very very very poor -- Tmills009, 2020-04-28 ### ***** "Works like a charm if photo quality is adequate" Make sure you take the photo of the sudoku puzzle with good lighting and without distortion then the app will do just what it is supposed to do. I tested it with some sudokus with the size of approximately 10 by 10 cm printed on non glossy paper with plain white background and recognition was 100% correct. -- j.p.kerspe, 2019-12-24 ### *---- "Pointless and not worth the download" Doesn’t work. It’s pointless -- Jenn0219, 2019-11-19 [View all SudokuScan reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## SudokuScan Discovered Keywords -
