Mobile game developer AirPlay shows off its latest interactive game, which lets football fans play along with the game as it's happening. The basic concept is simple: Fans click through a menu for each play and predict what they think will happen. If they're right, they earn points. The game will be available on Sprint's network starting Tuesday.
