You watch the ads more than you even play the game, which in my opinion is messed up. Also the gems just keep getting less and less the closer you get to having enough gems. I would not recomend this game, even I don't rush and I can wait for ads to end but this is just ridiculous. And at one point it gave me only 100 coins and no gems. This is a rip off of your time do not even try it.
