3 stars: Game had bugs at the start. Those were of course fixed and even with the ads after each game it still was a 5 star game. This last update though took away the ability to do previous daily challenges. Since I do these so quickly I save several to do at once. I have moved this to 3 stars until this is fixed back to allowing completion of any daily puzzle.
5 stars: The ads are kept to a reasonable level. The way the board is presented is very user friendly and in my case minimises misclicks. I have only tried the expert level and found some fairly easy to solve and some really difficult. Best sudoku app I have found.
4 stars: Very good app, pretty good puzzles generated. I would rate full 5 stars if they bring back the option to complete old Daily Challenges or offer more collecting activities/trophy earning in general. The calendar events are really good, I like the little graphic for the completion tracks.
4 stars: This is a fun game but I think it's easier than regular Sudoku because the totals given for each cage are great hints. It is a bit frustrating though because I spend so much time trying to see where each cage is. I don't suppose you could make those lines red?
4 stars: Overall has been a great app with just a few glitches. Ads aren't bad at all compared to other apps, but are present. Most recent change is pretty bad though. Limiting the daily puzzle to only be accessible day of. So if you miss a day, too bad \ud83e\udd37\u200d\u2640\ufe0f <...
