The Culling Game is a battle royale-style game in the Jujutsu Kaisen manga and anime series. It is a massive ritual that uses the barriers to trap cursed energy and make all of humanity evolve and merge with Tengen. The game is designed to prepare the humans of Japan for the merger. The players gain points by killing each other, and the game takes place across 10 barrier colonies located all over Japan. The rules of the game include:
- After awakening a cursed technique, players must declare their participation in the culling game at a barrier of their choice within 19 days.
- Any player who breaks the previous rule shall be subject to cursed technique removal.
- Non-players who enter the barrier become players at the moment of entry and shall be considered to have declared participation in the culling game.
- Players score points by ending the lives of other players. Points are determined by the game master and indicate the value of a players life. As a general rule, sorcerers are worth 5 points and non-sorcerers are worth 1 point.
- Excluding the point value of a players own life, players may expend 100 points to negotiate with the game master to add one new rule to the culling game.
- If a players score remains the same for 19 days, that player shall be subject to cursed technique removal.
The Culling Game is a complex and evolving storyline in the Jujutsu Kaisen series, and more details about the game may be revealed as the story progresses.
