I have been playing Sudoku for years and absolutely love this app! It has a nice variance in difficulty from easy to expert. The easy I enjoy doing quickly when I only have a little bit of time. The expert I need to sit down! Some of them can be really tough which makes for a fun challenge. I find the controls to be easy to use and the new setting for quick entry mode is fantastic! I've been able to lower my solve times just from that setting alone. It's nice to see those times going down in the stats dialog! No issues so far with stability which is nice unlike some other apps I have installed. I've started to try out some of the similar games like Calcudoku. So far it's pretty fun but I don't think I'll ever leave Sudoku! Thank you developers for this great game!

Great classic Sudoku app! I like the four levels of difficulty. Some of the expert modes I’m still trying to learn how to solve. Sometimes if I have five minutes on the train I’ll do an easy Sudoku just to bang one out since it’s still fun to play those ones. It’s nice to have the notes available and saved games to keep track of longer games. I love the new stats panel too! It’s fun to see my solving times over history on the charts. Please keep the features coming and thank you for this great Sudoku game!!

I like how this app looks and works but there are two things I have a problem with. First is the white screen bug. I have tried deleting the app and reinstalling it and that worked for a short while but the problem came back. The only way to keep playing when that happens is to shut off your phone and turn it back on again. The second issue is I wish there was a paid version to get rid of the ads. If those two problems were addressed I would give this app 5 stars because of its clean look and otherwise ease of use.

This app is simple and the controls aren't needlessly over complicated. It is a sudoku app with no ads, it doesn't take wifi or a lot of storage space. It doesn't say it's anything more than it is and it is nothing less. It's great for a quick game and it will save your progress without problem. It's perfect.
