US Patent 8342946 Computer graphics processing and display of selectable items

Systems and methods are provided for wagering during an event. In some embodiments, the system creates real-time markets for betting on outcomes during a live sporting event. The system determines odds for outcomes based on determined probabilities of those outcomes. A betting market is opened. A touch-sensitive display device displays a video of the game including a live image of a first location of a playing area. A bet is received from a first user based on touching the first location. After the betting market is closed, the bet outcome is resolved, and a payout is automatically paid to a winning bettor.
