100 Kids vs. 100 Parents: A 100-Hour Endurance Contest for $500,000

Open on YouTube ↗
Overview

MrBeast (Jimmy) built two large cubes, one holding 100 kids and the other 100 adults, many of them the kids' own parents. The rule was simple. After 100 hours, whichever cube had more people inside would win, and only the players still standing on that team would split half a million dollars. The video follows the two sides as MrBeast and his crew, Nolan, Karl, and Chris, try to thin both groups with bribes, pranks, and rule changes.

The Setup and the First Buyout

Before the doors closed, each side was asked whether it would lose to the other. The adults were reminded that even if they won, they would have to split the $500,000. One parent said they were "a giver" and would share a little.

One hour in, MrBeast offered $1,000 to anyone who left, with 60 seconds to decide. He stressed that this was the only time anyone would get money unless they won. Some contestants said $1,000 wasn't enough. Others took it, including a father and his son, whom the crew described as "like father, like son." After that single hour, 12 adults and 10 kids were out. One adult was frustrated that people had left with "like 88 adults" still in the cube.

With the committed players identified, the parents had to sign a document. It said the kids would spend any winnings responsibly and the parents would not use the money on themselves, if the kids won. One of the crew said they couldn't believe the parents actually signed it.

Living in the Cube

Chris and the other YouTubers brought in a porta-potty. The cube soon smelled so bad that the crew drilled a hole in the wall, which the contestants called "the fart pipe."

Five hours in, Nolan left everyone alone until morning to see what they would do. Bored, the contestants discovered they could pull up the floor tiles, and they started removing them. The next morning, one kid tried to find out how many adults were left. The crew accused him of cheating and escorted him "away from the 500 grand." The information he was after turned out to be locked, and his removal left both teams tied at 78.

Food as a Weapon: Oatmeal, Taco Bell, and Coffee

Breakfast was oatmeal, and contestants complained it had no sugar. One person walked out right after it was served. MrBeast remarked that "the oatmeal always works." Kids who had just left guessed the other team was winning.

Since nobody liked the oatmeal, Nolan offered the kids Taco Bell for everyone if two of them left. They refused. He made the adults a similar offer built around what they wanted most: 75 cups of coffee if two people left. The adults accepted, and Nolan went to Starbucks, where the employee asked, "75 what?" Although the kids had refused the Taco Bell deal, a few of them left anyway. Kids who stayed noted that every departure meant more money for them. The coffee delivery left the adults, as one put it, "happy and merry."

The Green Button

MrBeast then raised the stakes. A giant button sat in front of each cube. At some point in the next 24 hours, it would turn green, and whichever side pressed it first would shrink the other team's zone. Karl controlled when the color changed.

The adults said they had three people ready to run, and credited the coffee for keeping them alert. Karl flipped the button to blue to see if anyone would jump early. It worked, and at least one person got out. The kids were told only 50 of them remained and guessed the adults had around 60. Karl switched colors several more times before finally turning it green. The race was very close. One runner insisted they had arrived first, but was told the other side had "just barely" beaten them, a letdown for their team. By the end of day two, the kids were down by 18 people.

Pizza for a Smaller Zone

MrBeast's next offer was that if a team let him shrink its square, each member would get a whole pizza for dinner. Inside the cube, the group was split, with chants of "pizza" competing against chants of "oatmeal," but the offer was taken. One contestant apologized, saying "Jimmy's making me do it," and another said it was all they had wanted all day. The pizzas were delivered, one per person.

The shrinking space made the nights harder. Contestants said there was barely any room left. Told that 60 adults remained, one person estimated only around 15 kids were left, reasoning that the kids were getting the same oatmeal every day. Another thought their side was losing badly.

A Pipe to the Parents

By day four, boredom was taking over, so the crew arranged a surprise. The kids could talk to their parents through a pipe between the cubes. Kids called out to their moms and dads. One asked for "Jessica" and was told she was no longer there. A parent told their child to stay strong and "stay away from the red line."

The Empty Briefcase

The crew then tried a prank: carrying an empty briefcase into the cubes to tempt people out. It worked on the kids. One kid who left admitted they had been planning to leave anyway. Some contestants reasoned it might have held $10,000, but pointed out that in MrBeast's other videos the briefcase had always been empty, and that Jimmy had said the $1,000 was a one-time offer.

The crew assumed the adults would be too smart to fall for it. They weren't, and someone walked out. The crew ran it again with a single dollar bill sticking out of the case, aiming to "go four for four." Another person left and said they hadn't even noticed the dollar. A kid also got out on the same trick. On a later try, when an adult walked out to see what was inside, the crew noted that the kids hadn't fallen for that one.

The Balloons

After Jimmy had been absent for a day, contestants heard noises on the roof. The crew lowered balloons into each cube and said anyone who followed orders not to pop them would not be punished. The balloons got popped, and the notes inside said that because the balloon had been popped, that team's cube would shrink. The adults blamed Nolan, saying he had dropped it on the wall. The kids' balloon had also been popped.

One group was told it had passed the test. But while that was happening, someone had stepped on the line. Karl showed them the footage of their foot on the line, and they had to leave. On the way out, the eliminated player told the others they had made them more money.

Numbered Lines

Next, the crew brought in a table and asked each team's leader to pick a number between one and five. The number decided how many lines would divide the other team's cube. One leader picked two and the other picked three. When the kids saw what the adults had done to their cube, they thought it didn't look too bad. The crew explained that the lines took up little space but made mistakes much more likely when people stepped over them, including on the way to the bathroom. One contestant wondered why everyone kept crossing them.

$10,000 per Adult, and a Teacher's Reward

After another adult left, the adults were down to 50. If they all stayed and won, each would take home $10,000. The person who had left said they were glad to be the one who made that happen.

The kids had now missed five days of school. The crew asked who their favorite teacher was and visited her, Miss Mabe. They apologized for "borrowing" her students and dumped a pile of cash in front of her, asking her to count it. She promised that if the kids won, her math students would have no homework for the rest of the year. When the kids heard, they said they were going to win.

The Final Hours

With two hours left, MrBeast offered chocolate bars from his brand Feastables to anyone who would say "Hershey sucks." Most did, though one person said they liked Hershey's.

At 99 hours, someone stepped out, and a crew member gave them $5,000 even though, by their own account, Jimmy hadn't approved it: "better to ask for forgiveness."

In the last 30 minutes, confidence was mixed. Some kids chanted that they would win and prayed the kid cube had more people than the adult cube. One guessed there were 73 adults left. Another kid said they were ready for the adults to win. On the other side, a parent said the adults would win and apologized to their son, while someone else predicted the parents would lose.

The Result

After a ten-second countdown, the challenge ended and everyone came out front. MrBeast announced that the adults had won "by a landslide." As a thank-you for staying the entire time, the kids who lasted were each given $1,000. The video ends with kids finding their parents, some saying they didn't know how to feel, parents telling them they were proud, and the adults chanting "Go adults!"
