This edition features two legendary winners, Boston Rob Mariano and Sandra Diaz-Twine, who return to the game to serve as mentors to a group of 18 new players. Combined, Boston Rob and Sandra have played over 200 days in this game and plan to share their knowledge with the new castaways, but for the first time ever, they won't be competing for the money. During the 39 days, these new players will visit the Island of the Idols and learn skills and strategy from these "idols." The new players will then put their knowledge to the test and those who can rise up to the challenge will continue their quest for $1 million and the title of Sole Survivor.
