It's a decent sudoku game with cool in-game features. There are too many issues to justify paying for it though. The game resets your progress in-game whenever you close it, the ads are nonstop, and on nightmare level, I played a hint and it just filled in a box for me. Didn't explain what it was doing or why. This many issues in such a simple game makes me question the ability of the devs. Shouldn't be that hard to code this game correctly. And on top of that it's $7.99?? Smh. Don't pay ppl.

Hello, sorry for that. As a startup, we have to survive by integrating with ads. We've forwarded your feedback about ads and hint to our dev team. Since nightmare is so difficult we are now finding a better solution, too. Could you tell more details about your "Progress" issue? We'll continue to update our app. Thanks. - Fiona

I like the app very much, but I was having a problem, because the app sent me messages. I was worried that the app was running in the background and using up battery. It turns out there's a way to control that. I emailed the developer and they said, "You can turn off the notifications by going to your phone Settings - Applications - Sudoku - Notifications." I am very pleased with their rapid response. I changed my rating from a 3 to a 5!

Hi, we are sorry that the notifications bother you. You can turn off the notifications by going to your phone Settings > Applications > Sudoku > Notifications. If you meet the "starts up on its own" issue again, could you send a video? We'll further look into it and try our best to make it right for you! Thanks! :-) - Fiona

Interface is great. The game is simple, relaxing, and a good way to keep your brain active. The unnecessary events are excessive and cause undue lag. It's a simple puzzle game. There's no animation or anything that takes processing power. There is no reason for lag. Ever. The ads are too much. I keep getting force-sent to the play store repeatedly in the same minute for some popup blocker program ironically as well as some BET nonsense, in the middle of puzzles as well as before each.

Hi, sorry about this issue. We've blocked the ads from an ad network. Could you please kindly help to check if you will still have the same issue later? If it still doesn't work, could you please kindly take a video regarding the "Lag" and "play store" issue, and send it to We'll further look into it for you. Thanks. - Fiona
