Managing a subset of participants in an event

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.

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.

An article of manufacture comprising:

• a computer-readable medium that is non-transitory, in which the computer-readable medium stores instructions which, when executed by at least one processor of at least one computer in electronic communication with a plurality of other computers via an electronic communications network, 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.
