MyBookie is a very interesting development, crossing the boundaries between Facebook apps like Farmville and games on the phone itself.
MyBookie combines real-time Vegas lines with live sporting events. The game encourages players to build their fortune using strategy and personal ingenuity. The game features multiple betting scenarios including Game Spread, Moneyline, Over/Under, and Parlays, and supported leagues support includes NFL, NCAA Football, NBA, NCAA Basketball, MLB, and NHL!
The game also feature Facebook leaderboard integration and rewards.
The app is at the vanguard of a movement which make it easier to engage your own social graph in what is usually a solitary activity. Hopefully this is bandwagon which Microsoft will also jump on to, making it easier to engage friends who are not already Xbox Live users.
