Idk why but the ai is really hard to beat everytime I reach a challenge where I have to score three goals. It's exhilarating. And I even hate the fact that I often got silver & a few duplicate whenever I buy player. I know you can get better ball from it, but you have to be REALLY lucky. I don't like that and it makes me salty. I'm gonna uninstall this game if this game keeps teasing me _+
