The Final Three are three remaining contestants on Day 39 that are present at the Final Tribal Council to plead their case for the title of Sole Survivor. This is currently the only alternative format of the Final Two.
Introduced during the events of Survivor: Cook Islands, host Jeff Probst later explained that the reason behind adopting this endgame scenario would be to prevent a strong, well-liked individual from getting to face off against a less respected individual, so by adding a third player in the mix, the odds are changed.
Whilst fan reaction to the change has been received mostly positively, several castaways have adopted taking two other castaways to the end with them who have not done as much or been obnoxious, which in turn has coined a player who fits this mold as a "goat". It is also very common that only two of the three castaways in a Final Three receive votes.
