Abstract: Methods and systems for the sale of tickets to a particular event by a ticket source to buyers who can purchase a ticket to the event based upon the participation of a particular individual or team by making periodic payments towards such purchase for so long as the particular individual or team can still qualify to participate in the event. If the particular individual or team is eliminated from the possibility of participating in the event, the buyer's obligation to make any subsequent periodic payments to the ticket source lapses and the ticket source's obligation to deliver a ticket to the buyer for the event lapses. If the particular individual or team qualifies, and the buyer has made all the requisite payments to the ticket source, the buyer ends up “scoring” a ticket to the event from the ticket source. Others can bid to acquire a buyer's right to purchase a ticket from the ticket source.
