The castaways were welcomed to the game by Jeff with just their street clothes. After introducing themselves, the tribes were divided by schoolyard pick. As traditional in Gabon, Jeff announced that the oldest people usually make the decisions in the tribe and therefore the oldest castaways, Bob and Gillian, started the pick. After the tribes were picked, tribe names Fang and Kota were announced, and buffs passed out, Jeff announced the first challenge for individual Immunity Idols and extra food.

• Tribal Reward/Individual Immunity Challenge: The tribes would have to race across the plain and up a hill. The first castaway from each tribe to the top of the hill would win an Individual Immunity Idol that would only be good at their tribe's first Tribal Council. The first entire tribe to the top of the hill would win an extra bag of corn and beans.

Marcus and GC won individual Immunity Idols and Kota won the extra bag of food. At the Kota tribe, Bob and Ace took charge and organized the campsite. At the Fang tribe, a nighttime visit by an elephant spooked the tribe. Randy hit his head on the tribe's hut, requiring a visit by the Survivor medical team to put in several stitches.

• Reward/Immunity Challenge: Six tribe members would be belted together and have to race through a swamp, over a net wall, and under and over a series of hitching posts. The six would then have to dig up three bags of puzzle pieces and deliver them to the three remaining tribe members. These three would then assemble the puzzle pieces to win flint and immunity.

At a combined Reward/Immunity Challenge, Kota pulled far ahead while digging up the puzzle bags and won by a blowout. Before Tribal Council, Michelle and Gillian were targets for votes due to their negativity and age, respectively. Michelle's negativity outweighed concerns over age and she was voted out. After the vote, Jeff announced that Fang would be taking their torches back to camp and gave them a flint.

Picked as the leader of Fang at Tribal Council, GC started the tribe's first fire and organized jobs to fix up the campsite. At Kota, Charlie and Marcus formed an alliance; the two expanded their alliance to include Jacquie and Corinne. The four discussed bringing in Bob to have a majority, though Bob would be kept out of the core alliance of four. In the early morning of day 5, GC resigned his leadership of the tribe after arguing with Gillian over waking up early and making too much noise. After receiving tree mail announcing the next challenge, Dan tried to unify Fang by painting everybody with charcoal face paint.

• Reward/Immunity Challenge: The tribes have to roll a large ball through a series of gates. At two points along the course, a tribe member would have to climb atop the ball to retrieve of set of keys. At the final gate, the keys would unlock three chains that blocked the gate. The first tribe to go through all the gates and roll their boulder atop a short pedestal wins fishing gear and immunity.

Despite Fang's attempts to boost morale, Kota won their third challenge in a row. Kota selected Dan to go to Exile Island, where he chose to get a clue to the Hidden Immunity Idol, but he was not able to decode the clue to find it. At Fang, Randy fashioned a fishing hook out of parts from his glasses and the tribe was finally able to get some meat. Gillian suggested to Susie that the two of them form an alliance, fearing they might have been next in line to be voted out since they were the oldest women in the game; she suggested the two vote off Ken because Gillian thought he was useless. Dan's behavior after he returned from Exile Island made the others suspicious that he had found the Hidden Immunity Idol. This caused some of the Fang tribe to reconsider voting out Gillian, and instead vote for Dan. At Tribal Council, Gillian's weakness at physical challenges was seen as a greater concern than Dan's potential of having the Hidden Immunity Idol and she was voted out.

At Fang, the argument over who was or was not the tribe leader continued. At Kota, the rest of the tribe was annoyed at Ace's attitude of being king of the tribe.

• Reward Challenge: One member of each tribe would hang on to a post. Two members of the opposing tribe would attempt to remove the tribe member from the post and drag them across the sand to the finish line. The first tribe to get the member of the other tribe across the finish line would receive one point. The first tribe to score two points wins blankets, a hammock, pillows, and a mat.

At the Reward Challenge, Ace chose Paloma to hang onto the post. However, the Fang members easily overpowered her, leading to their first victory. They also elected to send Sugar to Exile Island. The win re-energized the Fang tribe and they finally felt like a team. Meanwhile, at Kota, Paloma's poor effort at the challenge caused her to be seen as the weakest link in the tribe. Corinne talked to Bob about joining her alliance of four, though she kept him in the dark about his status in the endgame. On Exile Island, Sugar elected to receive a clue to the Hidden Immunity Idol over comfort and followed the clues to find the Hidden Immunity Idol. Sugar then revealed that her father's recent death was the motivation for her playing the game.

• Immunity Challenge: One at a time, six tribe members would slide down a water slide. They would then swim out to retrieve a numbered tile, then run up the hill they slid down to drop their number off. Once all six tiles were retrieved, the remaining castaway would use the tiles to solve a numeric puzzle. The answer to the puzzle is a combination to open a locked chest which holds an ax. The first tribe to open their chest and use the ax to cut a rope that would raise their tribe's flag would win.

During the Immunity Challenge, Ken secured Fang's victory by overcoming Kota's lead at the tile retrieval stage and solving the numeric puzzle before Bob. After the Immunity Challenge and back at their camp, Sugar told Ace that she found the Hidden Immunity Idol while leading the others to believe she didn't have it. Paloma approached Corinne about forming an alliance and targeting Ace for elimination, due to Ace being manipulative and trying to set her up for failure at the Reward Challenge. At Tribal Council, Ace's attitude at camp was discussed, but the tribe chose to remove their weakest physical link and voted out Paloma.

After Tribal Council, Ace was upset at Kelly's animosity towards him and her vote against him. In retaliation, he targeted her for the next elimination. Over at Fang, an alliance of Dan, Matty, Randy, and Susie formed and targeted GC for elimination. The remaining members of Fang, Crystal, GC, and Ken formed their own alliance. When the tribes next gathered, Jeff announced that the castaways would rank their tribemates by secret survey according to their importance within the tribe. Kota ranked Marcus as most important in their tribe followed by Ace, Bob, Charlie, Jacquie, Corinne, Sugar, and Kelly. Fang ranked Matty as most important in their tribe followed by Dan, Randy, Crystal, Ken, GC, and Susie. After announcing the rankings, Jeff told the castaways to drop their buffs as they would be picking new tribes by schoolyard pick once again. Voted as most important within their tribes, Marcus and Matty stayed with their original tribes and started the draft. The new Kota was Marcus, Dan, Charlie, Randy, Corinne, Susie, and Bob, while the new Fang tribe consisted of Matty, Ace, Crystal, Jacquie, Ken, Kelly, and GC. As Sugar was not selected during the process, she was sent to Exile Island. She would stay there until after the next Tribal Council and then join the tribe that lost the next Immunity Challenge. Since she had already found the Hidden Immunity Idol, Sugar chose the comfort option at Exile Island. At the newly formed Fang campsite, Crystal noticed that Kelly felt like an outcast at the old Kota and invited her to join her alliance with GC and Ken.

• Immunity Challenge: The tribes would play a lacrosse-like game on the water. Each tribe member would be on a raft and have a paddle. Each round, Probst would toss a ball into the water. The castaways would paddle around the playing field, using the paddle to pass the ball from one tribemate to another. The first tribe to throw the ball three times into their opponents goal would win.

At the Immunity Challenge, Randy scored all three goals for Kota in their shutout victory over Fang. Kelly's poor performance at the challenge made Crystal, GC, and Ken reconsider their alliance with her, as they now perceived her as the weakest member of the tribe. However, they decided to target Jacquie instead, realizing that Sugar might have the Hidden Immunity Idol and with it, the trio of Ace, Sugar, and Jacquie would hold power within the tribe. They wanted to ensure that Ace in particular had as little power as possible, as he was also a physical threat. The three shared their plan with Matty to persuade him to vote their way, but he immediately informed Jacquie of the development. Jacquie tried to plead her case to Ken and Crystal, casting herself as an outsider who was not allied with Ace and really wanted to remain in the game. However, her effort was in vain, as the original Fang stuck to their plan at Tribal Council, voting Jacquie out.

Sugar arrived at Fang to join her new tribe and was surprised to see that Jacquie was voted out at the last Tribal Council. She continued to feign that she had not found the Hidden Immunity Idol, but Crystal did not believe her and targeted her next for elimination. On day 13, the Fang tribe were visited by an elephant just across the river from their camp.

• Reward Challenge: A tribe member would toss fruit through a hole in a wall to two members of their own tribe. An opposing tribe member would stand in front of the wall and use a club to try to knock away the fruit as it was thrown through the air. Once a piece of fruit is caught by a tribe member, it would have to be thrown through a hole in a second wall defended by a second opposing tribe member. The tribe that catches the most fruit by weight after five minutes would win an herb garden, salt, oil, chili sauce, and all fruit collected from the challenge.

At the Reward Challenge, a strategy change of tossing two fruit at a time over Ace defending the second wall helped Kota win the challenge by 2 pounds (0.91 kg). Kota chose to send Sugar to Exile Island for the third time in a row, with Dan stating that it was a strategy move to force her to play the Hidden Immunity Idol before the tribal merge as they wanted it back into circulation. At Exile Island, Sugar once again opted for the comfort. At the Fang camp, the pressure of the game started to get to GC and he argued with Crystal. Immediately before they were to leave for the Immunity Challenge, he went off alone in the tribe's kayak, causing his tribemates to call out for him. He returned just before they left for the challenge.

• Immunity Challenge: One member from each tribe would roll a large ball made of interwoven sticks down a hill. A blindfolded tribe member at the bottom of the hill would attempt to block the opposing tribe's ball with a shield and the aid of a caller. Behind the blocker would be a row of seven goals of varying point values. If a tribe's ball made it past the blocker and into a goal, they would be awarded the specified number of points. The tribe with the most points after five rounds would win.

At the Immunity Challenge, Fang was in the lead until the last round of the challenge when Randy, the caller for Kota, tricked Ace, the blocker for Fang, into stopping and allowing the last Kota ball to reach the goal. The final points were enough for Kota to win the challenge, continuing their winning streak. Before Tribal Council, GC told Matty that he was ready to leave the game. Crystal searched Sugar’s bag and found that Sugar had the Hidden Immunity Idol. Although Crystal, Kelly, Ken, and Matty believed that the upcoming Tribal Council was the ideal time to blindside Sugar, they decided instead to grant GC’s wish to leave and he was voted out.

The day after Tribal Council, Matty and Ace made a pact to take each other to the tribal merger as long as Ace could keep Sugar in the game and Matty could keep Ken in the game. Matty swore on his girlfriend and Ace swore on his mother's life. Over at Kota, Dan's extra helpings of food caused conflict among the tribe while the dwindling food supplies at Fang made them rethink their rationing of food. After Ace told Sugar that he thought the rest of Fang went through her bag and discovered the Hidden Immunity Idol, she gave him the idol for safekeeping.

• Reward Challenge: The tribes would be tethered to a 20-foot (6.1 m) long, 200-pound (91 kg) cloth snake. The tribes would start at opposite ends of an oval course. Both tribes would run counter-clockwise around the course and try to catch up to the other tribe. If a tribe member could not continue, they may unhook themselves from the snake and the remaining tribe members would continue the challenge. The first tribe to catch the other tribe and touch one of the opposing tribe members would win croissants, fruit tarts, chocolate éclairs, coffee, and tea.

At the Reward Challenge, Kota won their fourth consecutive challenge when Ken, Sugar, Kelly, and Crystal were unable to keep up and dropped out of the challenge, leaving an exhausted Ace and Matty to be chased down by the five men of Kota. Randy's taunting of an emotional Crystal did not sit well with her and she predicted that the old Fang and new Fang members would not get along. Kota chose to send Sugar back to Exile Island for the fourth time. Unlike her last visit where she enjoyed the food with the comfort, Sugar felt guilty about eating while her fellow tribe members subsisted on three scoops of rice. Kelly thought that Crystal crying after the Reward Challenge was a sign of weakness, but Crystal said that it was not.

• Immunity Challenge: The tribes would divide into three pairs. Each pair would be tethered together by a rope. The first pair would crawl under a cargo net, race through the jungle, go through an obstacle, retrieve two sections of a flag pole, and return to the starting line. The next pair would run the same course with an additional obstacle to retrieve the next two pieces of the flag pole. The final pair would run the course with two additional obstacles and retrieve the final two pieces of the flag pole. The first tribe to collect all of the flag pole pieces and assemble their flag would win.

At the Immunity Challenge, good teamwork by Kota during the flag pole assembly versus Ace trying to assemble Fang's flag alone allowed Kota to extend their winning streak to five challenges in a row. After the challenge, Matty approached Ace about blindsiding Sugar to flush the Hidden Immunity Idol, but Ace convinced Matty not to worry about the Hidden Immunity Idol being played and to vote for Kelly, though Ace did not tell Matty that he had the idol. Crystal also wanted to blindside Sugar or vote out Ace, but Matty told her of Ace's plans. Ken talked to Matty about blindsiding Ace, but Matty told Ken that he made a promise that he could not break. Lastly, Ken talked to Sugar about Ace and she told Ken that she had given the idol to Ace. Ken was unable to convince Sugar to change her alliances, but Ken did make sure that Sugar took the idol back from Ace. At Tribal Council, none of the blindside plans came to fruition and Kelly was voted out.

The day after Tribal Council, Crystal accidentally kicked over Fang's rice supply, which upset Ace and Matty. At the Kota camp, the alliance of Charlie, Corinne, and Marcus made Dan uncomfortable and he approached them feeling left out.

• Reward Challenge: In two roped off squares, three members of a tribe would toss a breakable ball back and forth. An opposing tribe member would attempt to smash or knock the ball to the ground. The first tribe to break the opposing tribe's ball would score a point for the round. The first tribe to score three points would win a helicopter ride to a picnic. Not announced at the challenge was an additional reward of letters from home.

At the Reward Challenge, Kota continued their winning streak by shutting out Fang 3-0; Sugar was chosen to go to Exile Island for the fifth consecutive time. Back at camp, Matty voiced his frustration at Sugar’s lack of effort at the challenge. Matty offered Ace a plan to vote out Sugar without Ace having to stab her in the back, but Ace wanted to vote out Crystal instead. Meanwhile, Ken talked to Crystal about blindsiding Ace. During Kota's reward picnic, a crew member of the helicopter surprised them with letters from home. At the Immunity Challenge, Jeff announced that both tribes would be going to Tribal Council, that they would be playing for Individual Immunity, and there would be a twist announced after the Challenge was done.

• Immunity Challenge: The castaways would compete in a head-to-head logrolling contest in a single-elimination tournament. Each castaway is matched up against another castaway. The first person to fall off from the log is eliminated from the challenge. The final round would have three castaways rolling the log at the same time. The last person remaining would win immunity.

Marcus won the Individual Immunity by defeating Sugar and Ace. The twist was that Marcus had to assign Individual Immunity to one member of the other tribe and he selected Sugar. After the Immunity Challenge, Ken, in an effort to blindside Ace, told Sugar about Ace and Matty plotting to vote her out. Later, Ace asked Sugar to give him the Hidden Immunity Idol, which made her think Ken's story was true. At Fang's Tribal Council, Ken's plan to blindside Ace came to fruition as Sugar cast the deciding vote against Ace and he was voted out. The afternoon before Kota's Tribal Council, Dan scrambled to keep himself in the game. Charlie, Corinne, and Marcus replaced Bob in their alliance with Randy, though they did not tell Bob. Susie upset Corinne by telling her she had planned to vote for her. Corinne immediately went to her alliance and told them that she wanted to vote out Susie. Corinne, Charlie, Marcus, Randy, and Bob split their votes between Dan and Susie, convincing each to vote for the other and hoping that the immunity idol would be flushed out if Dan had it in his possession. Ultimately, Dan was voted out.

Back at camp after Tribal Council, Marcus and Corinne addressed Susie over her opinion that she was a stronger player than Corinne. Over at Fang's camp site, the tribe tried to start over and looked ahead to an expected tribal merger. After tree mail hinted at a tribal merge, the castaways packed up their personal items and went to a beach for a feast. At the feast, a clue for a second Hidden Immunity Idol was tucked under a locked box that the castaways would open after the feast was over. Ken noticed the note first, but when he tried to get the note for himself, Charlie saw the note and forced Ken to share the note with everybody. When nobody showed much interest in going to find the idol for fear of looking greedy, Marcus proposed to dig up the Hidden Immunity Idol, but to throw it in the ocean so that nobody could use it. Although many were tempted to take the Idol, the castaways finally agreed to throw it into the ocean. When the castaways opened the locked box, they were instructed to each draw a numbered stone from a bag. A second note was then read, stating that they had just selected new tribes. Castaways with odd numbers would be the new Fang and the even numbers the new Kota. At the new Kota, Marcus identified Crystal as the cousin of one of his friends, forming a connection with her. The two agreed not to write each other's names down at Tribal Council, but Crystal later stated in a confessional she had no intention to be loyal to him. Marcus tried to convince Susie to join his alliance with himself and Bob. At the new Fang, Corinne felt that the greatest threat to her alliance with Marcus was Matty and she wanted to vote him out next. Matty told Sugar that Ace never targeted her contrary to what Ken told her and she felt bad about blindsiding Ace at the last Tribal Council. The two formed a new alliance. Concerned over how Susie would vote at a Kota Tribal Council, Randy talked to Charlie and Corinne about throwing the next Immunity Challenge to force Fang to go to Tribal Council where the three would vote out Matty.

• Immunity Challenge: The castaways would hold two poles on the tops of their hands up against a board over their heads. Any movement in their hands would cause the poles to drop to the ground. If the castaway dropped his or her poles, he would be eliminated from the challenge. The last person who does not drop their poles would win immunity for their tribe and keep all of its members safe. In other words, the first tribe to have all its members drop their poles would lose immunity.

At the Immunity Challenge, Matty outlasted Bob and he won the challenge for Fang, spoiling Charlie, Corinne, and Randy's plans. Marcus tried to keep the Kota six alliance going by approaching Crystal about replacing Susie in the Kota six and voting out Ken followed by Susie, but she did not want to vote out her ally, Ken. Marcus told a different story to Susie, telling her the plan would be to vote out Ken followed by Crystal. He also promised to take Susie to the final three. Not wanting to betray her long term alliance with Ken, Crystal told Ken what Marcus told her. Crystal tried to convince Susie that Marcus's promise of a final three was not possible because Corinne and Randy disliked Susie too much to allow that to happen. At Tribal Council, Susie decided to join Crystal and Ken, and they made Marcus the first member of the jury.

Several castaways expected a merge notice via tree mail, but instead the tribes received a Reward Challenge note. Upon seeing the Marcus-less Kota tribe, Charlie and Corinne were visibly shocked at their ally's ouster.

• Reward Challenge: The tribes would use a three man slingshot to shoot an oversized golf ball along three golf holes. The tribe that put their ball in the hole using fewer shots would receive one point. The first tribe to score two points would win an overnight trip to a Gabonese village.

Fang came from behind to win the Reward Challenge. Corinne announced that Fang was going to send Bob to Exile Island, hoping that he would find the Hidden Immunity Idol, but not knowing that Sugar had already found it. At Exile Island, Bob followed the clues to the Hidden Immunity Idol and found the location where the idol would have been. Unable to find the idol and thinking that Sugar may have found it, Bob fabricated a fake Hidden Immunity Idol that he hoped to use as a bluff. On day 27, before the start of the Immunity Challenge, Jeff announced that the tribes had merged.

• Immunity Challenge: The castaways would make a fire large enough to burn through a rope using flint, steel, and a box of fire making supplies. The first castaway to completely burn through their rope would win immunity.

Susie and Sugar were the only two castaways to get a fire started during the Immunity Challenge, with Susie being the first to burn through her rope to win individual immunity. The castaways returned to the old Fang campsite, found that they had received new food supplies, and named themselves Nobag ("Gabon" backwards). The alliance of Charlie, Corinne, and Randy saw Sugar as a swing vote at Tribal Council to vote for Crystal, whom Randy wanted voted out. Sugar told Charlie and Corinne that she could not live with Randy any more and Corinne tried to convince Sugar that if she voted with their alliance that they would vote Randy out next. To get revenge for forcing him to share the note about the second Hidden Immunity Idol at the feast, Ken decided to blindside Charlie by fabricating a story that Charlie was the brains behind the Kota alliance. Ken told the story to his alliance of Crystal, Matty, and Susie who believed his story and agreed to vote for Charlie. Ken told the same story to Sugar in an effort to get her vote for Charlie. At Tribal Council, Crystal confronted Randy over why he disliked her so much. Sugar joined the alliance of Crystal, Ken, Matty, and Susie, because she did not want to align with Randy and Corinne, and Charlie was sent to the jury.

Not knowing that Sugar had the Hidden Immunity Idol, Bob told her that he did not have it and showed her the fake idol that he made.

• Survivor Auction: Instead of a Reward Challenge, a Survivor Auction was held. Each castaway was given $500. Items won included food and drinks, a secret item for the next Immunity Challenge, the power to send someone to Exile Island and take their remaining money, and a hot bath with fresh clothes.

The second item up for bid was unknown as it was covered. After making the winning bid, Ken discovered he had won the right to send somebody to Exile Island and take their money. He chose Bob who immediately departed for Exile Island. For the second to last item at the auction, Corinne won a sealed bottle with a note that would give her an advantage at the next Immunity Challenge. Randy won the last item of the auction, chocolate chip cookies to share with the tribe. Sugar declined the first cookie offered to her which Randy then split between Matty and Corinne. Without taking one for himself, Randy offered Sugar the last cookie. She took it and gave it to Matty which upset Randy. At Exile Island, after getting no additional help from the Hidden Immunity Idol clue, Bob decided to go on a personal safari instead of looking for the idol. After the auction, Corinne and Randy talked to Matty about joining their alliance with Bob. Instead of joining with Corinne and Randy, Matty lobbied his alliance to vote out Bob next instead of Randy. Randy decided that the only option available to his alliance was to annoy the Fang alliance, get them to all vote for him, pull out the Hidden Immunity Idol that he assumed Bob had found, and blindside Susie at Tribal Council in revenge for her flipping to the Fang alliance. Randy told Matty that Matty had "whored [himself] out" to the original Kota alliance, at which point Matty rescinded his voting off order and gave into his alliance's want of voting Randy off.

• Immunity Challenge: In the first round, the castaways would race across a series of balance beams carrying a bag of puzzle blocks. The first two castaways to bring all three of their bags would go to the final round in which each player must stack all of their pieces like a line of domino tiles while avoiding ropes that would topple the tiles that were already stacked. Once all of the blocks were properly stacked, the castaway would start a chain reaction which would release a flag. The first castaway to raise their flag would win.

At the Immunity Challenge, Corinne's sealed note that she bought at the Survivor Auction stated that she would skip the first round and go directly to the final round. Despite her advantage, Ken defeated her and Matty in the final round. After the Immunity Challenge, Bob told Sugar that he still did not have the Hidden Immunity Idol and she told him that he should give his fake idol to Randy. Figuring that he had nothing to lose and it would keep him in the game, Bob agreed to Sugar’s plan and gave Randy the fake idol. At Tribal Council, Randy pulled out the idol before the votes were read. Jeff announced that it was not a hidden immunity idol and tossed the idol into the fire pit. The votes against Randy were counted and he was sent to the jury.

A recap of the first 30 days including previously un-aired bonus footage.

Back at camp after Tribal Council, Bob was upset at all of the laughing when Randy was voted out. Corinne and Sugar argued over how to play the game. At the Reward Challenge, the castaways got to view a short video clip from their loved ones before the schoolyard pick. Jeff said that the castaways' loved ones were not around the corner and he only had the videos of them. Because "today is all about love" according to Jeff, nobody was sent to Exile Island.

• Reward Challenge: The castaways would be split into two teams of three by schoolyard pick. The unpicked castaway would be ineligible to win the reward. The teams would be roped together and have to race through a swamp to collect seven sprocket pieces at two different stations. After collecting all the sprockets, the team would have to assemble them on a board in order to turn another sprocket which in turn would raise a flag. The members of the winning team would move on to the final round to individually solve a sliding puzzle. The first castaway to solve the puzzle would win a video from their loved one, pizza, beer, and brownies. Not announced at the challenge was an in-person visit from their loved one.

The schoolyard pick resulted in one team of Susie, Matty, and Ken and another team of Crystal, Sugar, and Bob; Corinne was not picked, so she could not win. The team of Bob, Crystal, and Sugar came from behind to win the first round of the challenge and moved on to the final round. Bob won the Reward Challenge by quickly solving his sliding puzzle first. Jeff then told the rest of the tribe that he had nothing for them and told them to head back to camp. While Bob was watching the video clip from his wife, she paused and said that there was "something I wanted to show you" and moved off-camera. Contrary to what Jeff said at the start of the Reward Challenge, Peggy, Bob's wife, was in Gabon and she stepped around the corner to surprise Bob. Bob and Peggy then walked hand in hand to the Nobag campsite to meet the rest of the castaways. After introducing his wife to the tribe, Bob turned and whistled to signal the other castaways' loved ones to make an appearance. Matty proposed to his girlfriend, Jamie. The loved ones departed camp before sundown. Bob shared with Corinne a plan to blindside Matty where Bob would make up a second fake Immunity Idol and tell the Fang alliance that it was the idol that Marcus threw into the ocean. Bob's story was that Marcus only threw the bottle into the ocean, had hidden the idol around the camp, and told Bob where it was.

• Immunity Challenge: The castaways would be asked trivia questions about Gabon. For each question answered correctly, the castaway would earn one ball. After four questions are asked, the castaways would throw the balls that they won down a hill at a target divided into zones. The castaway who throws their ball into the zone closest to the center of the target would win.

At the Immunity Challenge, Bob won by throwing his second ball one zone from the center. With Bob's win, Corinne expanded upon her blindsiding plan with Bob by concocting the story that Bob would have played the idol tossed into the ocean at the next Tribal Council, but since he won Individual Immunity, he would give Corinne the lost idol. Bob and Corinne hoped that the threat of Corinne having an idol would deter the Fang alliance from voting for her and would instead vote for Matty. Corinne told the story to Ken, which he believed and he suggested that Bob and Corinne approach Crystal with their plan. Bob told the story to Crystal and showed her the second fake idol. Crystal and Ken talked about their voting strategy under this plan where Ken would vote for Matty, Crystal would vote for Corinne, resulting in a 4-3 vote split between Corinne and Matty, respectively, Corinne would play the lost idol negating votes against her, the lost idol would be flushed, and Matty would be going home. At Tribal Council, the vote went as Crystal and Ken planned, Corinne's bluff was called and she was sent to the jury.

After the castaways returned from Tribal Council, Matty was upset because Ken voted for him. Ken told Matty about Bob and Corinne's fake Hidden Immunity Idol, but Matty did not believe him. Ken confronted Bob about the fake Hidden Immunity Idol. Bob promised Ken that if he won the next Immunity Challenge that he would give the immunity necklace to Ken.

• Reward Challenge: The castaways would race through a swamp and over several obstacles to retrieve one of three balls. They would then return to the start and toss the ball into a net. The first castaway to retrieve all three balls and get them into the net would win an overnight helicopter trip to a gorilla sanctuary in Loango National Park, a meal, a shower, and a bed to sleep in.

Bob won the Reward Challenge and chose to take Crystal and Ken along on the trip and to send Susie to Exile Island. While on the trip, Bob reiterated his promise to give the immunity necklace to Ken. Ken decided that he would only take it if he felt he was in danger of being voted out. On Exile Island, Susie selected the comfort choice because she knew that Sugar already had the Hidden Immunity Idol. Back at camp, Matty tried to get Sugar to give him the Hidden Immunity Idol. After returning from the reward trip, Crystal yelled at Matty for him questioning Crystal and Ken's loyalty to him. The yelling made Sugar change her opinion about Crystal and Ken. She told Matty that he would not be going home after the next Tribal Council and hatched a plan to take out Crystal and Ken.

• Immunity Challenge: The castaways would be blindfolded during the challenge. At the starting line would be a Gabonese mask. At the other end of a net obstacle would be a duplicate mask with some pieces removed. Three bags of puzzle pieces would need to be carried across the net obstacle one at a time. The puzzle pieces would then need to be assembled to replicate the mask at the start line. The first castaway to correctly replicate the mask would win.

At the Immunity Challenge, Bob won immunity for the second time in a row, marking his fourth consecutive challenge win. Ken told Crystal, Matty, and Sugar that Bob would give him the immunity necklace if they all told Bob that they would be voting for Ken, so they should tell Bob that and then vote for Bob instead to blindside him. Sugar told Bob of Ken's plan, that she would not vote for him, and to vote for Crystal. At Tribal Council, Bob and Ken said that their agreement over the immunity necklace would be that Bob would give it to Ken if Bob felt that Ken was in danger of being voted out. Jeff stated that this Tribal Council would be the last Tribal Council where the Hidden Immunity Idol could be played. Sugar was openly wearing the Hidden Immunity Idol. Before the voting started, Jeff asked Bob if he was going to give up the Immunity necklace. Bob stated that he was not going to give up the necklace as he thought Ken was not going to go home. Before the votes were tallied, Sugar gave the Hidden Immunity Idol to Matty who then presented it to Jeff. Ken and Crystal's votes against Matty were voided and Crystal, upon receiving the four remaining votes, was sent to the jury.

Ken felt that Bob reneged on his deal to hand over the immunity necklace at the last Tribal Council. Sugar worked on re-establishing Ken's trust in her even as she plotted with Bob to vote out Susie and Ken next.

• Immunity Challenge: The castaways would have to dig a hole under a wall, cross a maze made out of planks, and untie a series of knots that would open a gate that led to a maze with 25 Gabonese huts. In three of the huts would be a bag of puzzle pieces. One puzzle bag at a time would need to be retrieved from the maze and dropped off at the finish platform. Once all three bags were retrieved, the first castaway to correctly assemble the puzzle (a replica of a Gabonese hut) would win.

At the Immunity Challenge, Bob narrowly beat Sugar, winning immunity for the third straight time and the fifth consecutive challenge. At Tribal Council, Ken felt confident going into Tribal Council that he would not be voted out, but that confidence was misplaced as he was unanimously sent to the jury.

Before the start of the final Immunity Challenge, the Final Four took the traditional journey honoring the castaways voted out before them.

• Immunity Challenge: The castaways would be given 200 wooden tiles. The first castaway to use the tiles to build a house of cards 10 feet (3.0 m) tall would win. There is a time limit of 30 minutes for the challenge. If after 30 minutes, no castaway has built the house of cards to over 10 feet (3.0 m) tall, the castaway who builds the tallest house of cards at the end of the time limit would win.

Susie broke Bob's challenge winning streak by having built the tallest house of cards after 30 minutes. Sugar thought about forcing a tie at the next Tribal Council due to her loyalty towards Bob for being a father figure. Bob went off into the trees to practice starting a fire, anticipating a fire making tiebreaker challenge. At Tribal Council, Sugar did force a 2–2 tie between Bob and Matty. The tiebreaker challenge was to create a fire large enough to burn through a rope, which Bob won after resuscitating his initial fire to burn through his rope before Matty managed to even get one started. As a result, Matty became the final member of the jury.

The final three spent their last day at camp eating the traditional feast and burning down one of the huts at the campsite. At the final Tribal Council, Charlie asked Sugar and Susie why they felt they should be voted at the "top of the totem pole" even though they were ranked the second lowest and lowest, respectively, among their tribes before the first tribal switch. He asked Bob if the "intimate cuddling and spooning all night long" was more enjoyable than he would liked to admit. Crystal asked no question of Susie, asked Bob to tell her something that Sugar didn't tell him to do, and asked Sugar why she voted her out. Ken asked Susie why she thought she deserved the million dollars and his vote, asked Sugar why she back stabbed him, and Bob about their deal over the immunity necklace. Corinne asked Susie if she would be willing to have her vocal cords removed if she were to win the million dollars. She asked Bob to show the nasty side of Bob and make her believe that he did not like Sugar. She took the opportunity to make a callous comment about Sugar’s deceased father, to which Sugar gave an obscene gesture. Marcus asked no questions of Susie, what Sugar would do to honor her deceased father if she were to win, and for Bob to give one example of a situation in which he was responsible for his decisions. Randy asked Susie to elaborate on the time that Susie said she felt sorry for him and Sugar and Bob if they considered the consequences of putting him on the jury when they gave him the fake Hidden Immunity Idol. Matty asked Susie to tell him why Bob and Sugar were less deserving that she was of the million dollars, Sugar to reveal something that she felt that she did was evil, and Bob why Sugar and Susie were more deserving of the million dollar prize than he was.

Months later, the votes were cast and the jury revealed Bob the Sole Survivor receiving four jury votes while Susie received the remaining three and Sugar received nothing. The castaways return to discuss the season with host, Jeff Probst.
