I assume the point of most apps is to get money, but this app doesnt try to hide it at all. You really cant do anything without watching advertisement after advertisement only to gain coins or bucks. The other option is to play a lot of games, but then you have to deal with losing a lot because, like others are saying, you get matched poorly with teams much better than you. The gameplay is very fun, and I enjoy the idea behind it, but I easily spend 25% of my time on this app actually playing the game. So unless you have a few hours to kill, I would try and find another app.
