In the event of a tie, all tied users split the total value of the prizes awarded to the tied places. For example, if 2nd place in a contest pays $500 and 3rd place pays $200, if two users tie for 2nd place, they each would receive a payout of $350.
For satellite contests, if more users tie for tickets than there are tickets available, then no tickets will be awarded for those tied places. Instead, the tied users will split the value of the ticketed seat as a cash prize. For example, if a contest awards five $25 tickets and two users tie for the fifth ticket, both users would forfeit the ticket and instead receive cash payments of $12.50 each.
For other contests with special non-cash prizes, the rules for each specific contest will cover how ties are handled.
