Ratings and reviews

Excellent capture of printed Sudokus. Solves or lets you solve with pencil marks even. Touch number, then all the cells you want to place--adjust pencil marks or make solutions. I'd like to try doing my own marks first, maybe that option will come. Warns it was built for an earlier Android than mine, but does almost all I want. Interface is awkward, but worth the time to figure. When all cells solved... SILENCE?? shucks🤔👀👍

This hasn't been updated since 2017 and it is the only Sudoku app I use on a daily basis. Love that I can capture puzzles from newspapers and other print formats. The only thing I would want is dark mode since I am up late often playing this. Either way, I haven't found a Sudoku app to replace this. Kudos to the developer who makes this available for free with no ads. Definitely 5+ stars.

I have been happily using this app for several years but I recently upgraded my Pixel 4a to Android 12 and now the top 2 rows of the Sudoku Vision puzzles are not visible. The game screen is the correct width but not being able to see the top of the puzzle makes the game unplayable. I can't find a way in the settings to change the screen size so I contacted the developer and I haven't heard back yet. I wonder if anyone else has a solution.
