5 stars: An interesting take on sudoku with the levels challenge. The daily puzzles and different difficulties also give me lots of options to play, a real good brain workout at different tiers for different times. Edit: the developers are very responsive and take suggestions into consideration, kudos to the team and thanks for again for a great app!
5 stars: Like that you can choose different skill levels. Sometimes you want more of a callenge, sometimes not.
4 stars: Nearly perfect sudoku app. Very few popular adverts and only the occasional banner at the bottom. No way to turn off the sounds under the settings.
4 stars: Expanding the mind.. Hardly any adds and dnt want to put it down
3 stars: dropped to 3 star becaùse adverts keep stalling & when you restart the game it incorrectly reports you have made 3 mistakes & you have to start again
3 stars: All the sudoku are blending but either I am asked to upgrade, deny it and it still upgrades or there are way too many advertisements for games. Less is better. I just get so annoyed that I flip the phone over and think about deleting.
2 stars: The game keeps resetting and I have to restart the levels every few weeks. It's happened 4 times so far. I don't log out or delete the game. I get a message about ads and it resets the levels. Made it to 617 and it reset to level 1 again.
2 stars: The game is so bad for me.I play over level 1000 and now let me start with level 1.This is second for me.
