This game is fun at first BUT it becomes almost impossible once you get to a higher level. You ABSOLUTELY have to pay to win or you're stuck. They will pair you with people almost double your health with unbeatable heroes. And beware when spending money. They have it set up where it won't affirm your gem spending so accidental clicks are easy to make. I thought I hadn't gotten 300 gems but apparently I spent it somewhere without even knowing. Customer service is no help.
