The ads are horrible-but you will not regret upgrading to pro. This app is very good, with no glitches or bugs that I have seen. Though there are no penalties in the game, it is very fun to play. I bought this during the free sale, but anyway, this app is totally worth it. You definitely need to work hard to score goals which makes it more like hockey.
Why am I not rating 5 stars? Well, the graphics are not very good, and the ads at first are constant. They keep having you "watch videos" to unlock things. Its all a bribe. Paying the $1.99 is worth it though, because it makes it extra fun since ads dont get in your way.
I read reviews before upgrading and debated whether I should pay $1.99 or not. I decided not to believe what other people said and Im pretty much right. The glitches people said that were not fixed did not occur to me, and the game worked out really good. Not only do you play games with the computer, you can do seasons which eventually lead to the playoffs. (Im doing good so far
