About SportXction(TM)

SportXction(TM) is a patented, real-time, software system, which allows a player to make play-by-play wagers on a sporting event while the event is in progress. Wagering may be conducted while viewing a live or televised sporting event, or listening to it on the radio. The wagers offered are mostly oriented to short-term action, for example, is the penalty kick successful, is the next play a run or a pass, is the next pitch a ball or a strike, does the shooter make two foul shots, and many more. The wagers have odds associated with them, which relate to the probable outcome of the proposition being wagered upon, and the odds are adjusted in real time to balance the pool using proprietary artificial intelligence software to reflect player sentiment, as derived from the betting patterns. The system can be used with virtually any sport.
