What was the Culling Game for, and did it work?Fiction

In-universe lore. Claims are judged against the fiction's own canon, not the real world.

Jujutsu Kaisen's Culling Game is a rule-bound battle royale fought across ten barrier colonies, and the arc is argued over for its mechanics as much as for its fights. This is the sourced record of what the rules actually say, what the game was staged to achieve, and how far the text takes it.

  • The arc's rule load is read both ways: it is called difficult to follow even for manga readers because of the sheer number of rules, colonies and characters, and notorious for heavy exposition dumps stemming from the game's complex mechanics, while another reading holds that things become clearer as its battles go on.▰▰▰▱▱ likely1 against4 points

  • What the Culling Game was collecting is argued over inside the story itself: it was originally believed that gathering the players' cursed energy into the colonies was the primary goal, and that reading was challenged on the grounds of the number of players, the wide difference in skill, and rules that emphasize permanence.▰▰▰▱▱ roughly even chance1 against2 points

    • Reggie Star argued that couldn't be the case due to the number of players, the wide difference in skill, and the rules of the game that emphasize permanence. Strong players weeded out the weaker ones within the first twelve days, resulting in several colonies quickly reaching a deadlock. If the true goal of the Culling Game was to use the players' cursed energy, then a lengthy battle royal would be more suitable.Culling Game (The Great Merger, Ch 167) - Jujutsu Kaisen Wiki primary

  • Cursed technique removal, the penalty for missing the Culling Game's declaration deadline, is sometimes described as being carried out via Idle Transfiguration, but the mechanic is elsewhere described as a mysterious process that does not involve Idle Transfiguration.Refuted byCursed Technique Removal is a mysterious process that does not involve Idle Transfiguration. Shoko Ieiri theorizes that it affects the player's brain and would kill them. Otherwise, all the players could simply refuse to participate.

  • The idea that Kenjaku personally decides whether a newly proposed rule stands does not hold: the ritual required him to take a binding vow that he is not the game master, and the game master itself is left vague.Refuted byIn order to perform such a ritual, Kenjaku has undertaken specific binding vows, one of them being that he is not the game master. This works against Megumi's group because killing Kenjaku will not end the game. The Culling will continue until all the players are dead and its rules ensure that nothing can interrupt the ritual.refuted2 against3 points

  • The identity of the Culling Game's game master is left vague: little is known about it, and the shikigami that act as the game's interface are described as the programming of the game rather than its actual masters.▰▰▰▱▱ likely3 points

  • The Culling Game has unaddressed rules that come about due to the barriers: answering Kogane's message on entering a colony randomly transfers a player to one of nine pre-established locations, which both spreads players out and catalyzes a secondary awakening within new players.▰▰▱▱▱ likely2 points
