Overview

MrBeast built two large circles, placed 100 boys in one and 100 girls in the other, and set a single rule: whichever circle has more people in it after 100 hours wins $500,000. Anyone who touches the red line marking the edge of their circle is out. The video follows how each team held up over four days of boredom, bad food, sleep disruption, temptation, and a series of twists designed to thin the ranks.

The rules and the incentive to leave

The money is split across the entire winning team, including people who have already left. Participants worked this out immediately: even if they quit, they would still get about $5,000 each if their team won. That detail shaped much of what followed, since leaving early did not mean giving up one's share.

The boys opened by chanting insults at the girls, and the girls chanted back. When MrBeast asked whether anyone wanted to leave, the boys shouted no, yet two stepped out almost at once. One explained that he had promised his girlfriend a night out, and the others chanted "sucker" at him. Another said he could not risk the job he had just gotten after graduating for $5,000. After 20 minutes, five boys had left and no girls had.

MrBeast addressed how line violations would be caught: more than 65 cameras covered every square inch of both rooms, with a team watching everyone's movements. Portable toilets were then delivered by forklift, driven by a crew member described as having no forklift certification, so both teams had somewhere to go to the bathroom.

Why people left

Several girls described obligations outside. One said her cat was alone in her apartment with three days of food. Another had not taken the next day off work and had a 3 p.m. flight to Chicago on Friday. One woman left because she has a child. MrBeast said many contestants had jobs and family expecting them that night or the next day, and that this was exactly what he wanted. It was why he told them nothing about the competition before it started.

The crew also had participants judge each other. A GoPro on the red line caught a boy very close to the edge, and MrBeast asked the boys to rule on it. They said he was in. MrBeast played a few more seconds of the footage, which showed the boy stepping on the line, and he was eliminated.

The girls had been far ahead early, but then many of them left, betting that their team would win without them. The boys took the lead. One girl remarked that four more had just walked out. Others argued that $5,000 would change many people's lives. At one point 20 girls were out. A boy said the departures were good news for them, since the boys had no idea how many girls remained.

Oatmeal, the first night, and a meal reward

For dinner, both teams got oatmeal, which they ate on top of piles of cash. One participant called it psychological torture. MrBeast reported that the boys lost 16 people to the oatmeal and the girls only 4. One girl complained about the raisins and estimated about 20 in her bowl. MrBeast said the teams were almost neck and neck.

Space was tight. One participant said that looking left meant a face, and looking right meant toes. During the first night, seven boys and nine girls left, and MrBeast guessed the boys must have slept better. In the morning he teased each team with the other's headcount: he offered to go count and then didn't come back. He told the boys that 62 of them had made it through the night. The boys were oddly enthusiastic about another round of oatmeal. The girls were not.

Boredom set in. MrBeast said the girls made things out of money, including a money jump rope, money hopscotch, and small money dolls. The boys' circle descended into chaos, and one of them asked MrBeast to forgive them their sins. MrBeast noted that people were leaving in different ways. Some were out by accident, some couldn't handle the pressure, and one girl left to rescue another contestant's cat.

At the 24-hour mark, the girls were brought hibachi chefs to cook dinner in front of them. One girl pointed out that the boys should be fed too. The boys, who had spent two hours listening to the girls enjoying themselves, then received a surprise meal of their own.

Sabotage, a scholarship interview, and hidden car keys

Because not much was happening on day two, MrBeast let Karl and Nolan annoy the contestants while they slept. Each team was given a loud siren presented as a "gift" from the other team. The girls switched theirs off. The boys smashed theirs, and one boy called it the worst day of his life.

By the morning of day three the rooms had started to smell, since nobody had showered. MrBeast said that the previous night a boy named Kevin had told Nolan about an important Zoom call for a scholarship. Nolan bought him a suit and a laptop so he could take the call from inside the circle, which MrBeast thought seemed like a bad idea. During the interview, the other boys crowded into frame and shouted things like "party all day, party all night." The interviewer told Kevin he was keeping his composure well and that she was proud of him. One onlooker predicted Kevin would get the scholarship.

At 43 hours, MrBeast said both teams had earned a prize for putting their bodies on the line. He had customized a blue Nissan for the boys and a pink Nissan for the girls, and hid each set of keys in that team's portable toilet. The first person to find them would keep the car. The crew then watched person after person go in and out without finding anything. Eventually Karl checked the boys' toilet and found the keys were gone, because a boy already had them. He got the car plus $5,000 for gas. Afterward the boys were convinced other prizes were hidden in the circle and began searching. One boy said they had smashed a glass hoping to find something at the bottom, and admitted that being the most destructive person there was pretty fun.

The Rubik's cube race

At 50 hours, MrBeast celebrated the halfway point with a race. Each team got 100 Rubik's cubes, the first team to solve all of them would win, and the losing team's circle would be cut in half. The crew only realized once the race began that just one boy and one girl actually knew how to solve a cube. The others did what they could, such as solving the white face and passing cubes to the solver.

Because the boys were far ahead, MrBeast decided to raise the stakes. He offered the boys' solver $10,000 to leave immediately. The boy kept solving while the offer was made, his teammates urged him to take it, and he left. MrBeast then told the girls he had paid off the boys' solver, so if they didn't win, it would all have been for nothing.

The boys still won the race. The girls' circle was cut in half, and the only girl who could solve the cubes ended up leaving. She said she had solved 96 cubes and still lost.

Temptation tests: briefcases and a red button

As the third night approached, MrBeast wanted to see which team would give in to temptation more easily. Nolan placed an empty briefcase outside the boys' circle, and a boy stepped out to grab it. It was empty. Nolan produced a second briefcase and fooled the boys again; this one contained cereal. Then another boy, trying to reach a briefcase without leaving the circle, crossed out anyway.

The same trick on the girls failed. One girl warned that whoever went for it would look like an idiot if there was no money inside. Nobody took it, and MrBeast concluded that the girls were clearly smarter. At 1 a.m. the girls said they were going crazy in their halved circle.

After three days, MrBeast said he could not believe how close the contest was and that both teams still had a chance at the money. At 70 hours, the boys guessed that 20 to 25 girls remained.

On day four, a girl told MrBeast she had found the car keys in the girls' toilet. She and her friends had kept it quiet so the other girls would not panic. MrBeast showed her the new car and told her she could leave whenever she wanted. She said she was definitely staying.

Next, MrBeast placed a podium with a big red button in each circle without explaining what it did. Behind the scenes, he said pressing it would halve that team's circle. The girls called it suspicious and decided to play it safe. A boy pressed his immediately, and the boys' circle was cut in half with spray paint while the girls chanted that boys suck.

Later, one girl convinced a camera operator to let them use a drone to spy on the boys, and it nearly crashed into the boys. On the fourth evening, the teams were allowed to cook their own food, because MrBeast said the next day would get much harder. At 85 hours, one participant said they didn't think many of them would last and that the girls were winning.

The final ten hours: shrinking the circles

For the last 10 hours, each circle was split into 10 sections. Every hour, each team had to choose one section to block off, and touching the new red lines still meant elimination. This led to some heated strategy talks. One team considered fitting nine people into the portable toilets to save space. The boys picked their first section very quickly. MrBeast said the fact that the teams were still so even after 90 hours was so statistically unlikely that it was driving him crazy.

Teams debated what to give up. The boys initially seemed sure about the "money pit," then reversed course, and that section was eventually painted over. With four hours left, the choice came down to the money pit or the toilet.

Then the lights changed in the boys' room. MrBeast showed footage of a boy named Xavier clearly touching the line with a finger. Another boy had touched it after coming out of the toilet, and a third was caught as well. One boy said they were losing people through carelessness. MrBeast said everyone was careful after that and made it to the final hour. In that last hour, a bunch of boys crowded into a single portable toilet, and one said he just hoped 33 would be enough.

The result

When the contest ended, everyone met in the middle of the dome. Of the 100 girls and 100 boys who started, 33 boys and 35 girls remained after 100 hours. The girls won the $500,000 by a margin of two people.
