This game is good. They get you to play then at a certain point you don't get enough gems or coins to go forward. When you lose a level you don't even get the coins you worked for on that level. You get may 30 and then you have to watch an ad to double which won't give you enough to go further or make upgrades. Most likely to be deleted when you can't go further. I like this game sucks it really just doesn't let you go further after a certain point.
