4 stars: Amazing game, a Stress buster for me. And the levels are challenging when it gets harder. I found some UI issues to them, later they fixed. The one thing I do not know how to exit the game. I always just minimized it.
3 stars: It is not progressively more difficult. You just get new and different challenges, so it remains fun. Some levels will be super hard, but then the next is easier. I really like the variety. ***The app is very buggy lately. They fixed bugs on 6/24 and now it is stuck on level 1615 because it won't give anything but plain blocks.
2 stars: So I love this game and play it all the time, but I gave it a low score because the adds are annoying. When you lose a round you can choose to keep playing for free if you watch an add. The thing is, All the adds are the same. They get so annoying when you have two adds about Mistplay app that they play All The Time. I wish they'd get some new adds!
