5 stars: I like the game... But hate ads. It would be great if there was a way to buy a way to never see ads. One other thing, I would prefer the UI to allow number placement from touching the number, without needing to touch the open square first. Update: I hadn't looked at the game well enough to make the above comment...it has the option of choosing a number first, I just hadn't discovered it yet! That makes this game a 5 star game for me!
5 stars: Very addicting puzzle game! Fun and enjoyable. Challenging puzzles.
4 stars: Really good challenge but sometimes a bit too much guessing required on the most difficult levels.
