Island of the Idols is a twist used in Survivor and is the titular twist of its 39th season.


The Island of the Idols appears to be a variation of Ghost Island where castaways may wager their vote to play a game of chance in exchange for game advantages. However, instead of a lottery, castaways will be mentored and challenged by two former Survivor winners, Rob Mariano and Sandra Diaz-Twine.

The island prominently features giant busts of Rob and Sandra. As stated in an oath recited by Rob and Sandra to each castaway sent to the island, both mentors are not competing for the million dollar prize, though they live under the same conditions as the actual contestants, albeit with better supplies and rations.
S39E01 IoI Oath

"The Oath of the Idols" recited by the mentors to each visiting castaway.

At random points in the game, castaways will be banished to the Island of the Idols, where they will be welcomed by Rob and Sandra. The mentors will teach the castaways survival skills and winning strategies. The castaway will then be given a choice to take the mentors' challenge. If a castaway accepts and passes the challenge, the mentors will award them an advantage in the game such as Hidden Immunity Idols or Extra Votes. However, if a castaway loses the challenge, the contestant loses the right to vote the next time he or she visits Tribal Council. If a castaway refuses to take the challenge, Rob and Sandra may tempt them into taking it.

Previous disadvantages imposed by Exile Island and Ghost Island such as the castaways being away from their tribe, ostensibly from its social dynamics, remain.
