Used to be the best Sudoku app. Most recent update completely breaks usability.
★★☆☆☆Mickael C· Sep 3, 2022
Game is good, but the latest update introduced new features that degrade the visibility, and cannot be turned off... Too bad.
★☆☆☆☆Cate Malone· Nov 12, 2025
Please add the old color scheme, the new one is too chaotic, I cannot tell what's selected as colors are too similar I'm more than happy to change my review if these criteria is fixed please.
★★☆☆☆Bludra Kuře· Mar 5, 2021
Color picker in themes is broken. I can't play, when even and odd cells have different color, and I can't pick black
★☆☆☆☆Nick Daniels· May 25, 2025
Input modes are buggy and messed up. Tick marks only have the option for all and have to be manually edited and that is also messed up and buggy. Who messed up this upgrade?
