Lowering my rating to 2. This is not a free to play game. I'm at a forced wall. In order to advance I need hundreds of gems. The only way I can get gems is play ads. Ads give you up to 8 gems per 30 second ad. So you could get 1 gem for every ad. My next pregress is 500+ gems. Do the math. That's hours of ads to barely advance in the game. I could by their bundles and that would barely do anything. I would get more play time out of a $60 console game.
