Was fun at first, and I'll admit a spent a few bucks in it. But after playing for a while you eventually reach a point where you start losing consistently because the people you are matched against are loaded with the gold cards. The game trys to force you to spend more, and you can't win more than 2 out of 5 matches until you do. I've spent more time playing this game than any other mobile game, and I have still yet to get a gold card, even with spending a few bucks. Doesn't work for me.
