Wonderful Sudoku game!

I have been playing Sudoku for many years and I currently have 6 other Sudoku games on phone. This one is quickly becoming my favorite. It has all the possible options. Different difficulty levels. Mistake limits. Auto complete. Time limits. Everything!
To all the others. Please only review the game itself. Don’t simply complain about ads. Ads are advertisements. Advertisements are commercials. Commercials are commerce and commerce is money. They need money to make the game so complaining about ads is just a waste of everyone’s time.

Great game but some issues

I love this game! But I’m having issues when I close the app and then open it again and try to play my last game I was playing, it just completely starts me over 😔 doesn’t save any of my progress! Even the notes on it are gone. It’s got to the point to where I don’t even want to play anymore. Anyway to fix this issue? would love some feedback! Has anyone else faced this problem? How did you solve it?

Teaches how to solve

I like how this app shows you the rules on Sudoku so that you know what to look for when you get stuck. I don’t like the ads. The game is on a timer, so I will be thinking about my next move when it breaks into an ad. Then when it returns I have to refocus, and remember what I was doing, which takes more time. So it’s not really a reflection of how long it actually would have taken you if you were allowed to follow through without distraction. In other words, the timer is kind of a moot point. There are lots of settings though, so I’m not sure yet if it’s an option to just turn it off. It’s a good app.
