Twists/Changes

 * ' Format:''' The two competing tribes, Manono and Salani, will be competing against each other while living together on the same beach in a more indefinite time. After the Tribe Switch and Reward Challenge in Day 12, the tribes were separated.
 * Battle of the Sexes: The cast will be divided according to gender, similar to both and Survivor: Vanuatu. Salani and Manono were the all-women and all-men tribes respectively, before the Tribal Shuffle on Day 12.
 * "Do-It-Yourself" Challenges: Similar to how a Reward Challenge in was conducted, certain challenges would require the contestants to run the challenge themselves, with no host overseeing them.
 * Hidden Immunity Idols: Though there will be only one camp, there will still be two Hidden Immunity Idols, one per tribe. If someone finds the other tribe's idol, they cannot use it. Instead, they must give it to a member of the opposite tribe before the next Tribal Council. Furthermore, for the first time, no clues would be provided.
 * Tribe Shuffle: The tribes were switched on Day 12, mixing the men and the women.

Season Summary
The 18 castaways were split into gender-based tribes and given maps to their camps, unaware they would lead to the same location. Despite living on the same beach, the tribes would remain split, building separate shelters and fending for their own tribe.

On the women's tribe, Salani, a five-person alliance was formed between Alicia Rosa, Chelsea Meissner, Kat Edorsson, Kim Spradlin, and Sabrina Thompson, who were able to control the votes on their tribe. Despite a strong start, the men (Manono) found difficulty with Colton Cumbie, an outspoken member of the tribe who was initially an outsider, often interacting with Salani instead. After Sabrina accidentally found Manono's Hidden Immunity Idol, she gave it to Colton, who used his new found power to overthrow Manono's dominant alliance and gain control of the tribe.

After a Tribe Switch, Colton found himself again in a position of power on the new Manono tribe, however he was medically evacuated from the game after being diagnosed with acute appendicitis. Meanwhile, on the new Salani tribe, Kim and Chelsea formed a second alliance with Jay Byars and Troyzan Robertson as a backup plan in case their original alliance failed.

Though the sexes entered the merge with equal numbers, the women decided to form a voting bloc. Jay and Troyzan chose to align with the women, betraying two of the men. Troyzan logically explained to Kat and Christina Cha, who were at the bottom of the women's alliance that after the men go they are next. They decided to stick with the women and vote out Jay and Troyzan anyway.

As a result, Tarzan Smith was the last man remaining. However, Kat's unpredictability and youthful naivety was enough to convince Kim that keeping Kat around may be a bad idea, blindsiding Kat in a unanimous vote. With only six players remaining, Kim found herself caught between her initial alliance of Chelsea and Sabrina, and the alliance of Alicia, Christina, and Tarzan. Although Alicia wanted to vote Chelsea out, Kim convinced Alicia that Tarzan was planning to betray her, leading to his elimination. Alicia and Christina were subsequently voted out at the next two Tribal Councils.

At the Final Tribal Council, the jury castigated Chelsea for acting as Kim's main pawn and lack of social play, and while they praised Sabrina for her social game, she was berated for her poor challenge performance and being lazy at camp. The jury blamed Kim for all of their eliminations, with Kim taking responsibility for every blindside. Ultimately, Kim won the title of Sole Survivor of by a vote of 7-2-0.
