Ratings and reviews

Switching to another app or even glancing at notifications makes the game "out of sync" and requires a restart. Wait for it to reload and you get served two ads, even though you have a paid subscription to remove them. One of the ads opens the Play Store, which again makes the game out of sync. The added insult is that the notification that started it all was a spam email from Microsoft.

Paid for the subscription, but regularly it shows me ads anyway and doesn't give me the XP multiplier promised. Shoddy work, and makes no sense for this to be a subscription app... Just let me buy it and be done. Also the touch UI is so buggy. If you touch anything (or sometimes even if you don't) it'll turn off the notes mode as a surprise and cause you to get a mistake when you weren't trying to fill in the box, just mark a number as a note. OMG. Fix this.

Favorite sudoku out there, I just wish I could get a lifetime subscription. Until then I'll just put up with the ads. My only complaint is that when I accidentally miss the little ">>" or "x" it takes me to the Play store, and even though I try to get back to the Sudoku app, it resets everything and reloads it like I just opened it. 😞 Otherwise, super fun app with new challenges each day!
