Koh-Lanta: Thaïlande

Koh-Lanta: Thaïlande is the 18th season of Koh-Lanta, the French version of Survivor.

Twists

 * Tribe Selection: After the marooning, the 20 castaways arrive at a beach where they must spend the first night. They find a message saying that the next day, only 18 of them will form the tribes: they must choose two of them that will stay on the beach. On Day 2, the 18 contestants who left the beach are divided into two tribes by a Schoolyard Pick led by the youngest man (Marius) and the youngest woman (Wendy).
 * Island of the Necklaces: This is an island away from the two tribe camps, where several Immunity Necklaces (equivalent of Hidden Immunity Idols) are hidden. In the first episode, the two castaways who stayed on the first beach are taken to this island. They stay there until Day 4, before the second Reward Challenge, where they join the tribes. Immediately after, each tribe must send a contestant from the opposite tribe to the Island of the Necklaces. These contestants will not take part in the next two challenges, and will skip Tribal Council. This is repeated in every pre-merge episode until the switch.
 * Tribe Switch: A message was hidden on the Island of the Necklaces, giving "a great power" to its founder. When the exiled return from the island, all castaways are told that a tribe shuffle will occur with a new Schoolyard Pick. The message founder becomes the captain of their former tribe, and must also choose the captain of the opposite tribe.

Voting History
Notes:

Charlie elected to quit the game. No vote occurred for her removal and Laureen was added into the game to replace her.

Cassandre and Steve stayed at the marooning beach, and spent the first days of the game on the Island of the Necklaces.

Laureen was introduced to Karwaï during the first Tribal Council. Because she did not spend the first days with the tribe, she was immune and could not cast a vote.

Marius elected to quit the game. No vote occurred for his removal.

This contestant was sent to the Island of the Necklaces before the Reward Challenge, thus did not attend their tribe's Tribal Council.

Tribal Council resulted in a tie. Per the rules, a second vote was held where the castaways could only vote for those involved in the tie, while Carole's black vote did not count anymore.
