The game itself is fun to play, but I'm giving it 1 star for the annoying pop-up ads. EVERY. SINGLE. TIME. I DO EVEN THE SIMPLEST THING 5 ADS POP UP. If I wanted to spend money, I would. Yes, I'm sure I don't want to spend any money. If I wanted to invite a friend, I would. Again, I'm definitely sure I don't want to invite anyone to this game If I wanted to buy a booster pack, I would.
