There are 120 Stages and 30 Bosses in the game at present, each of which contains normal, hard, and crazy difficulties. Therefore, it means that there are totally 450 stars available now. Every time you get victory in a level, you will get one star. Get more stars and you will unlock more blue chests with generous rewards.

We are still trying our best to add new stages and new features to the game. Let's look forward to it. Thanks for your patience and understanding!
