Managing a subset of participants in an event

Abstract

A method of managing bets is provided. The method includes receiving win bets and group bets. Each win bet includes a bet that a participant selected from a set of participants in an event will win the event. Each group bet includes a bet that one of a subset of the set of participants will win the event. Results of the event identifying a winning participant from the set of participants are received. An amount of a win bet payout for at least a portion of the win bets that comprise a bet on the winning participant is determined. An amount of a group bet payout for at least one of the group bets is also determined. In this manner, a bettor may bet on all participants in an event other than a particular participant, such as the favorite participant, and thus effectively bet against the particular participant.

1 . (canceled) 
     
     
         2 . A method comprising:
 receiving one or more group bets by a computer system, each group bet designating a corresponding subset of the set of participants in the event, the subset including a plurality of participants but less than all participants in the event, and being a bet that pays if any one of the corresponding designated subset wins the event, the pay amount being substantially the same whichever participant of the designated subset is the winner and independent of finishes other than the winner;   receiving, by the computer system, data representing results of the event identifying a winning participant from the set of participants;   receiving, by the computer system, data representing payment associated with one or more bets;   determining, by the computer system, data representing an amount of a group bet payout for at least one of the group bets based on the group bets designated subsets of which the winning participant is a member; and   determining by the computer system, whether to cause payment of the amount of the group bet payout at a payment interface.   
     
     
         3 . The method of  claim 2 ,
 wherein the at least one group bet is received in a pari-mutuel betting system,   wherein the act of receiving one or more group bets comprises receiving a first group bet made by a bettor, and   wherein the act of receiving the first group bet comprises receiving from the bettor a single amount representing an amount at risk in the first group bet.   
     
     
         4 . The method of  claim 2 , wherein two or more of the group bets designate the same subset of participants. 
     
     
         5 . The method of  claim 2 , further comprising:
 receiving one or more win bets, each win bet comprising a bet that a participant selected from the set of participants will win the event; and   determining the win bets that comprise a bet on the winning participant.   
     
     
         6 . The method of  claim 5 , wherein the amount of the group bet payout is determined based at least in part on the total amount of the win bets that comprise a bet on the winning participant. 
     
     
         7 . The method of  claim 5 , further comprising the steps of:
 determining the odds of winning for a one of the participants that is not included in a one of the designated subsets of participants based at least in part on the one or more received win bets; and   wherein the amount of the group bet payout for the group bet covering the one designated subset is determined based at least in part on the odds of winning for the one participant.   
     
     
         8 . The method of  claim 5 , wherein determining the amount of the group bet payout comprises:
 selecting a participant from the subset of participants; and   determining the total amount of the win bets that comprise a bet on any participant in the set of participants except for the selected participant.   
     
     
         9 . The method of  claim 2 , further comprising:
 receiving a notification that one or more of the participants will not compete in the event at the computer system; and in response, canceling at least a portion of the group bets that designated the non-competing participant in the respective designated subsets.   
     
     
         10 . The method of  claim 9 , further comprising the step of:
 reallocating the amount of at least one of the cancelled group bets among the remaining participants in the designated subset of participants.   
     
     
         11 . A computer system comprising:
 at least one processor; and   a memory electronically coupled to the at least processor and having instructions stored thereon that when executed by the at least one processor direct the at least one processor to:
 receive one or more group bets, each group bet designating a corresponding subset of the set of participants in the event, the subset including a plurality of participants but less than all participants in the event, and being a bet that pays if any one of the corresponding designated subset wins the event, the pay amount being substantially the same whichever participant of the designated subset is the winner and independent of finishes other than the winner; 
 receive data representing results of the event identifying a winning participant from the set of participants; 
 receive data representing payment associated with one or more bets; 
 determine data representing an amount of a group bet payout for at least one of the group bets based on the group bets designated subsets of which the winning participant is a member; and 
 determine whether to cause payment of the amount of the group bet payout at a payment interface. 
   
     
     
         12 . The computer system of  claim 11 , wherein the memory electronically coupled to the at least processor and having instructions stored thereon that when executed by the at least one processor direct the at least one processor to:
 receive a notification that one or more of the participants will not compete in the event at the computer system; and in response, cancel at least a portion of the group bets that designated the non-competing participant in the respective designated subsets.   
     
     
         13 . The computer system of  claim 12 , wherein the memory electronically coupled to the at least processor and having instructions stored thereon that when executed by the at least one processor direct the at least one processor to:
 reallocate the amount of at least one of the cancelled group bets among the remaining participants in the designated subset of participants.   
     
     
         14 . The computer system of  claim 11 , wherein the at least one group bet is received in a pari-mutuel betting system,
 wherein the act of receiving one or more group bets comprises receiving a first group bet made by a bettor, and   wherein the act of receiving the first group bet comprises receiving from the bettor a single amount representing an amount at risk in the first group bet.   
     
     
         15 . The computer system of  claim 11 , wherein two or more of the group bets designate the same subset of participants. 
     
     
         16 . The computer system of  claim 11 , wherein the amount of the group bet payout is determined based at least in part on the total amount of the win bets that comprise a bet on the winning participant. 
     
     
         17 . The computer system of  claim 11 , wherein the memory electronically coupled to the at least processor and having instructions stored thereon that when executed by the at least one processor direct the at least one processor to:
