This is the worst game ever. Trust me I am not exaggerating. This is a wast of your time for multiple reasons, 1 it is trying not to let you get enough gems. The more you progress the less you earn I started earning 0.01 gems per round right when I am about to reach my goal. 2 packed with ads ads every time and when you keep playing and try to get ads to get more gems it won't let you. 3 It is boring the levels are not even fun. Please don't get this THING. It is horrible.
