The Culling Game in Jujutsu Kaisen is one of the most dangerous and complex events in the story. Created by Kenjaku, it's a deadly survival game where sorcerers and awakened humans are forced to fight each other. At first, the rules may seem simple. But as the game unfolds, it becomes clear that each rule plays a bigger role in a twisted plan.

Some rules encourage killing. Others open the door to strategy, alliances, and betrayal. To fully understand what’s at stake, let’s break down every rule in the Jujutsu Kaisen Culling Game, starting from the easiest to the hardest to understand.


List of the Jujutsu Kaisen rules

1. Players score points by killing other players

In Jujutsu Kaisen, the simplest rule in the Culling Game is that players gain points by killing other players. This turns the entire event into a deadly battle royale. The game rewards violence, since in order to survive, one must be able to gain and hold points.

And because maintaining a pulse is the key to your score, you have no choice but to fight, whether you want to or not. It was an ominous start to the game. It’s brutal and unforgiving, much like the world of Jujutsu Kaisen. If you want to live, you have to fight to kill to make yourself safe.


2. The value of a player's life is determined by the game master

Jujutsu Kaisen adds another layer by assigning different values to lives. Sorcerers are usually worth five points, while non-sorcerers are only worth one. This makes stronger fighters more valuable targets, which creates a strategy in choosing who to kill.

Players will often avoid low-value kills since they need to stack up points fast. It also adds tension for sorcerers, who become high-value targets. This rule makes players think before striking. Every move counts, and going after the wrong person could be a waste. Or a deadly mistake.


3. Once a player awakens their cursed technique, they have to participate within 19 days

In Jujutsu Kaisen, once someone gains a cursed technique, they only have 19 days to join the Culling Game. They get to choose which colony to enter, but they must join one. This rule applies to players who were awakened by Kenjaku. An example of a person like this is Tsumiki Fushiguro. This rule forces new players into action quickly. It doesn’t allow anyone to sit on the sidelines.

Whether they’re ready or not, they must jump into the chaos. And in 19 days. This builds urgency and tension around new awakenings. In Jujutsu Kaisen, the moment someone unlocks power, their clock starts ticking. And if they don’t act fast, the game will punish them.


4. Players who break the participation rule will lose their cursed technique

The punishment for not joining within 19 days is the removal of your cursed technique. In Jujutsu Kaisen, that’s basically a death sentence. You won’t survive the game without a cursed technique. This rule ensures every awakened player becomes active, or they face serious consequences. It adds even more pressure to new players and forces them to step into danger.

If you choose to disobey the senior sibling of this rule, there are consequences. No one gets a pass. In Jujutsu Kaisen, the game makes sure everyone is involved and no one escapes responsibility. If you have power, you either use it or lose it.


5. Non-players who enter a colony become players instantly

Jujutsu Kaisen raises the stakes with this rule. Anyone who enters a colony, even by accident, is automatically part of the Culling Game. That means civilians or people just passing through are pulled in. They’re considered to have declared participation, whether they wanted to or not. For the people who were inside the barrier at the start of the Culling Game, they will have a chance to escape.

This rule creates fear and unpredictability. You could be living a normal life and suddenly be thrown into a deadly fight. In Jujutsu Kaisen, the colonies are war zones, and stepping inside changes your life forever. It’s a brutal and fast way to grow the player count.


6. If a player's score is unchanged for 19 days, they will be subject to the cursed technique removal

This rule keeps everyone moving. In Jujutsu Kaisen, if you don’t earn points for 19 days, you lose your cursed technique. It stops players from hiding or trying to survive by doing nothing. You must come out of your hiding spot and make contact with others. You need to fight or find a way to earn points every 19 days at least.

This adds more pressure and makes the game more active. Even skilled fighters can be in danger if they go too long without action. In the Culling Game, being passive is just as dangerous as fighting. This rule pushes everyone into the chaos, whether they like it or not.


7. Players can enter and exit any colony

This rule gives players the freedom to move between colonies. In Jujutsu Kaisen, it adds a level of strategy. Some colonies are more dangerous than others, so a player might move to find weaker opponents or escape a threat. It also allows allies to reunite or enemies to track each other.

This flexibility was not intended by Kenjaku. This rule was added by Yorozu, as it was not one of the original rules of the Culling Game. This kind of rule is rare in death games. Most lock you in. But Jujutsu Kaisen uses this rule to make things more dynamic. Movement can mean survival or doom, depending on who’s chasing you. Or who you’re chasing.


8. Players can transfer points to one another

Point trading introduces alliances and deals. In Jujutsu Kaisen, players don’t have to kill to increase their score. They can also receive points from others. This changes how the game is played. You can team up, save someone, or get points in exchange for favors.

It creates a loophole for some other rules that involve points. It also creates tension and trust issues. Will your ally betray you later? Will someone help you or leave you to die? It was Hiromi Higuruma who added this rule to the game. This rule brings a social side to the Culling Game, making Jujutsu Kaisen more than just fighting. It’s also about relationships and manipulation.


9. Players can see basic info about other players

Jujutsu Kaisen lets players know who’s in the game. They can see names, point totals, rule changes, and colony location. This info gives an advantage when planning moves. And with a couple of other rules in the Culling Game, this rule makes a lot of difference. You can track powerful players or avoid dangerous ones.

It also helps allies find each other. But this rule cuts both ways. If others can see your info, you’re never really hidden. In Jujutsu Kaisen, being known makes you a target. This rule adds to the mind games. Are you hunting or being hunted?


10. No new players can join after November 18, 2018

The deadline for new players locks in the roster. In Jujutsu Kaisen, this rule means no outside help is coming. You’re stuck with the players already inside. As of 9.09 pm on November 18, 2018, no one can join the game anymore. Weirdly, this rule was added by Kenjaku. And of course, there was an underlying motive.

This rule raises the tension and signals that the end is coming. It also means every player left matters more. No one is just background. Each fighter still in the game has a role in how it ends. In Jujutsu Kaisen, this rule sets the stage for the final battles and cuts off any chance of saving the game with new faces.


11. A player can use 100 points to add a rule

This is one of the most important rules. In Jujutsu Kaisen, players can spend 100 points (not including their own life value) to create a new rule. This gives power to players who are smart and strong. With the right rule, someone can change the game completely. But they must earn those points first. Because the condition on the rule creation is that it cannot cause another rule to be removed.

Meaning that if a character wants a rule, they have to make it to 100 points quickly before a counter rule is created. That’s not easy, as it involves a lot of fighting. And death. This rule creates hope and strategy. It’s not just about killing. It’s about playing smart. In Jujutsu Kaisen, knowledge is power, and with 100 points, that power becomes real.


12. The game master must accept rule changes unless they break the game

Jujutsu Kaisen gives the game master some control, but not total power. They must approve rule changes unless those rules ruin the game. That means most suggestions are allowed. The game master is not directly known, but the shikigami known as Kogane was how players interacted with the game. But the rules added can not have a long-lasting effect on the game.

Players have the chance to shape their own fate. This rule makes every 100 points even more valuable. Smart players can flip the game in their favor. It adds a layer of risk and reward. In Jujutsu Kaisen, being clever might matter more than being strong. If you can work hard to get the points, and live long enough to use them.


13. Players can use 100 points to leave the game by inviting a substitute

Escape is possible, but not easy. In Jujutsu Kaisen, a player can use 100 points to leave the Culling Game by replacing themselves with someone else. The game uses 100 points as a minimum currency for a lot of things, and this rule is one of them. This is one of the darkest rules. You’re saving yourself, but dooming another. The rule was created by Megumi Fushiguro to allow Tsumiki to successfully exit the game.

The Kogane accepted this rule after his first two iterations were not accepted. It shows how cruel the game really is. Even your freedom comes at a price. This rule forces players to think about what kind of person they want to be. In Jujutsu Kaisen, survival is never clean. It always costs something. Or someone.


14. The game ends when all players but three are dead

Jujutsu Kaisen sets a final goal: all players must die except Suguru Geto, Megumi Fushiguro, and Shiori Himi. This rule shows that the purpose of the game isn’t random. It’s designed to benefit certain people. That makes everything more twisted. It was Kenjaku who added this rule to ensure that either he or Sukuna would win the game.

Players aren’t just fighting for survival. They’re fighting in a rigged game. Most of the sorcerers know that, but don't care because they enjoy the thrill of fighting. This rule explains why some people can’t die yet. The Culling Game isn’t fair. It’s a setup with a brutal ending already in place.


15. Megumi Fushiguro holds the power to activate the Great Merger

The most complex rule in Jujutsu Kaisen gives Megumi the key to the next phase. The Great Merger is a huge event tied to the endgame. Only Megumi can start it. That makes him the most important piece on the board. This rule adds huge pressure and changes how people see him.

He’s not just a player. He’s the trigger for something far bigger. The rule was added by Kenjaku as a failsafe in case anything happened to Guguru Geto, Megumi Fushiguro, or Shiori Himi. In Jujutsu Kaisen, the Culling Game is only part of the plan. The real danger might come after, and Megumi is the one who holds that future.


Conclusion

The Culling Game rules in Jujutsu Kaisen aren’t just about survival—they reveal the larger goals behind Kenjaku’s plan. From simple kill-for-points rules to complex twists involving rule changes and final conditions, each part adds tension to the story.

As the game went on, these rules shaped every move the characters made. Some players tried to escape, others used them to gain power, and a few were caught in a game they never wanted to play. Jujutsu Kaisen uses the Culling Game to show just how far the fight between fate and free will can go.
