Ratings and reviews

So happy to have found this! It fixes the "problems" with the original from Roman Mašek. And when I say problems, I mean that over the years the Android OS broke backward compatibility and you could no longer get to the menu. I don't blame the developer at all for this, but I'm thrilled that someone has taken it up and modernized it. Thank you!!!

The latest update changed my customised colours. As somebody with poor vision, this is a terrible experience. Made the game unplayable for me. As much as I've tried, I cannot restore the colours to how I had them. Really poor move from the devs on this one

I love this app. Latest update crashed within 5 sec. Had to do uninstall and reinstall to purge my puzzle library. Was playing through a million easy puzzle collection which seems to have been the problem. Open Sudoku still rocks.
