5 stars: Great implementation. I've tried several sudoku apps and settled here. The developer regularly adds new ways to play. I would suggest they add the ability to scroll through the daily challenge screen by year for the long term players. Scrolling by month can be tedious.
5 stars: Good Sudoku game with clean interface, multiple difficulty levels and daily challenges. Ads are not intrusive - one ad is shown after each game, and that can also be skipped after a few seconds.
4 stars: Nice app, not too expensive to remove ads. I like the difficulty levels. It would be nice, if in event challenges it was also possible to change difficulty level. I would like to participate in events, but solving dozens of easy puzzles just kills me. Also in daily challenge if i solved todays puzzle, but haven't solved yesterday's one, I'd like the highlight cursor to jump to the unsolved one, not stay on the last one
3 stars: I like this game a lot, play it every day. Since you have too many and too long annoying ads. I decided to subscribe yearly. But I have the problem now after you updated the app. The numbers are too small that I can't play. Please fix it. I still have 11 months left for my subscription but I can't play. Edited stars. I can't play anymore though I already paid for the whole year, everything is so tiny, very annoying.
3 stars: The game itself is good but the adverts are overriding the fun - every other screen is too much - and as if that wasn't enough some...
