Survivor (American TV series)
In the event of a tie at the final four, there will be a revote (However, in Survivor: Gabon, there was no revote in the final four and it went straight to the fire-making tie breaker challenge), but if the revote does not break the tie, the tied players will compete in a challenge.  In Palau, Panama, Cook Islands and Gabon, this challenge was a fire-making contest.  In Marquesas, the random rock tiebreaker was used at the final four, which host Jeff Probst later said was a mistake.
