Ratings and reviews

I'm back to 5 stars. I had reduced my rating because of trouble with how some ads where handled. THEY FIXED IT! The game is back to a 5 star. It's again, hands down, the best I've played on line. The new feature, allowing the user to customize the keyboard layout, is great. I've told my friends about this sudoku app, try it and you will too.

The latest update messed up the ability to replay slowed games to improve time. Edit to add: I already had the latest update dated 8/22/2023. The problem is not fixed on my Samsung Galaxy Note 10+ running Android Version 12. Edit: Thanks to the developer's help I'm able to replay slowest games but it's a long series of taps to get there each time I wish to do so.

This is one of the better-written sudoku games for Android devices. It's not perfect but is very good. I've tried many others and have uninstalled all but this one. One knock on it is that you used to be able to replay completed games, say your slowest game in each difficulty level, but it seems to be unavailable now. Please bring it back! (I don't have any of the ads-related issues that others have commented on.)
