Game rule

Game rules are a set of customizable options for a specific in-game world.

In Java Edition, game rules can be changed using toggle buttons on the "Edit Game Rules" menu built into the "Create World" and "World Options" screens. The game rules are split into categories named "Player", "Mobs", "Spawning", "Drops", "World updates", "Chat", and "Miscellaneous".

In Bedrock Edition, about half of the game rules can be changed from the "Create New World" screen and the world options in both the "Edit World" screen and the game settings in the pause menu. The remainder can be changed only with commands, or in the "Export" interface in the Bedrock Editor.
