Survivor: Iguazu Falls, also stylized as Survivor: Iguazu Falls- Flops vs Finalists vs Favorites, is the thirty-fifth installment in the Koror ORG Survivor series.
The season was announced on December 28th, 2017. Applications open a little over a week later, on January 7th, 2018.
- Flops vs Finalists vs Favorites- The returnees will be split into three groups based on their best previous placement. Misiones, the "Flops" tribe, consists of players whose time in the game ended during the pre-merge, yet had potential to make big moves. Curitiba, the "Finalists" tribe, consists of players who have proven they can make it to the end, with some even winning the game. Parana, the "Favorites" tribe, consists of everyone in between, well known players that dominated the merge portion of the game, yet didn't have what it takes to reach Final Tribal Council.
- Simplified Tiebreaker- In an event of a tie at Tribal Council, the re-vote would be retired, and an open forum would commence. If the non-tied players are unable to make an unanimous decision who to eliminate, the rock draw takes place.
- Idol Grid- Hidden Immunity Idols will be in play this season. However, they will found in a grid shaped in the form of 26 letters by 26 numbers. Contestants will guess coordinates in order to find idols. While most spots will be empty, some spots will contain items that aren't idols, but aren't necessarily bad either. But with those good items, there will also be punishments and penalties hidden. It will be up to the player whether they are willing to risk receiving a punishment in order to find a reward.
- No Escape - Players are not allowed to quit the game. They must ask to be voted out by their tribe at the following tribal council if they wish to leave.
