Survivor: Edge of Extinction is the 38th season of the American CBS competitive reality television series Survivor. The season featured 14 new contestants competing with four returning players. This season introduced a new feature wherein contestants who are voted out have an option to take a boat to the titular "Edge of Extinction" rather than leave the game permanently. The Edge of Extinction is a desolate, abandoned beach with even fewer amenities than the main island: contestants on the Edge of Extinction may either wait for an opportunity to re-join the main game or may choose to leave the game at any point by raising a white sail. Castaways on the Edge of Extinction were given regular correspondence by way of coded maps and letters, which led to the location of daily rice rations and advantages in the game. The remaining contestants were initially unaware of this twist; it was officially revealed at the tribal merge, at which point the remaining Edge of Extinction castaways competed in a challenge with the winner returning to the game. The losing castaways were given the opportunity to remain on the Edge of Extinction and, from that point on, all remaining Edge of Extinction inhabitants went to each Tribal Council as members of the jury.
