Abstract: A method of managing bets includes receiving first types of bets and second types of bets. Each first type of bet comprises a bet that the number of units earned by a participant in a plurality of events will fall within a first range of numbers. Each second type of bet comprises a bet that the number of units earned by the participant over a course of a plurality of events will fall within a second range of numbers. The total number of units earned by the participant is determined based on the positioning of the participant in each event. The method includes determining whether the first or second type of bets are winning bets. A betting pool is determined based on the total amounts associated with the first and second types of bets. A payout is determined based on the betting pool and the total amounts of the winning bets.

Abstract: A method of managing bets includes receiving a first bet at a first quote, the first bet having an associated first unit stake, the first quote corresponding with the total number of units potentially earned by a participant in a plurality of events. Results of each of the plurality of events are received, which may include the positioning of the particular participant in each of the plurality of events. The total number of units earned by the participant in the plurality of events may be determined based at least in part on the results of each of the plurality of events. An amount of a payout for the first bet may be determined based at least in part on the first unit stake, the first quote, and the total number of units earned by the participant in the plurality of events.

Abstract: A method of managing bets comprises auctioning a first bet to one of a plurality of clients for a first bet amount, wherein the first bet comprises a bet that a first participant will finish in a particular finishing position associated with an event. The method further comprises auctioning a second bet to one of a plurality of clients for a second bet amount, wherein the second bet comprises a bet that a second participant will finish in the particular finishing position associated with the event. The method continues by adding the first bet amount and the second bet amount to form a betting pool, and determining an amount of a payout based at least in part on the betting pool.
