Hope this doesn't sound to much like an ad, but this new websites pretty cool. As someone that wants to get into sports betting, this seems like good practice. You join, and join different leagues and basically put up fantasy cash betting on different games. There's some system with coins and winning prizes later on, but I don't really care too much about that. The interface leaves a bit to be desired, but it is in beta. Pretty interesting and fun if you're not into blowing hundreds of dollars gambling.
