Ratings and reviews

This game used to be easy to interface with. In the last forced update, they changed the color scheme to make the background darker behind the black letters. Now it is very hard to read when you have two numbers penciled in the same cell. Need more contrast between letters and background.

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.)

9/15/17: Fun and addictive. 3/15/19: I've played a TON of the games, and each of them are different. Each game is challenging (to the degree of low, med., high, etc.), and the game is STILL addictive. Keeps the brain cells functioning, and defeats boredom. Had the 'pencil' option, and for the more challenging levels, it really comes in handy! It's got a timer option so you can play against the clock, and it's also set up so that you can see how your time ranks with others. Definite fun!
