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"​^{[upcoming JE 26.1]} 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.

When in-game, game rules can be changed using the /gamerule command, using the syntax /gamerule <rule> [<value>], where <rule> is the name of the game rule and <value> is an allowed value, which depends on the type of the game rule. The types are boolean (where the allowed values are either true, or false) and integer (where any whole number is able to be entered).

The following is a list of game rules available in-game, their allowed values, and their availability in Java Edition and Bedrock Edition.

The categorization of game rules is based on Java Edition, except for Bedrock Edition exclusive game rules. The minecraft: prefix has been excluded from this list for the sake of brevity.

Some game rules can be changed in Bedrock Edition without cheats (either by /gamerule command or the world menus, e.g., World Options and Create New World), thus safely keeping achievements enabled while configuring these game rules.

Rules affecting chat output, including command feedback, death messages, and advancements.

Rules controlling item drops from blocks, entities, and mobs, including drop decay mechanics.

A collection of technical or utility rules that do not fit into other specific categories, such as command limits, debug info, and other mechanics.

Rules that manage mob behavior, such as mob griefing, anger mechanics, and raids.

Rule name	Description	Default value	Type	Availability in Bedrock Edition
forgive_dead_players	Makes angered neutral mobs within 65 x 21 x 65 blocks centered on the targeted player stop being angry when the player dies.	true	Bool	Java Edition exclusive
max_entity_cramming	The maximum number of pushable entities a mob or player can push, before taking 6HP entity cramming damage per half-second. Setting to 0 disables the rule. Damage affects Survival-mode or Adventure-mode players, and all mobs but bats. Pushable entities include non-Spectator-mode players, any mob except bats, as well as boats and minecarts.	24	Int	Java Edition exclusive
JE: mob_griefing BE: mobgriefing	Whether creepers, zombies, endermen, ghasts, withers, ender dragons, rabbits, sheep, villagers, silverfish, snow golems, ravagers and end crystals‌[BE only] should be able to change blocks, and whether mobs can pick up items. When mob_griefing is disabled, piglins do not pick up gold ingots, but a player can still barter with them by using the item on the mob. Similarly, villagers do not pick up food items but can still breed until they run out of any food already in their inventory. This also affects the capability of zombie-like creatures like zombified piglins and drowned to pathfind to turtle eggs.	true	Bool	Cheats only[menu 2]
raids	Whether raids are enabled.	true	Bool	Java Edition exclusive
universal_anger	Makes angered neutral mobs attack any nearby player, not just the player that angered them. Works best if forgive_dead_players is disabled.	false	Bool	Java Edition exclusive

Rules directly impacting player mechanics, such as damage sources, keep inventory, and respawning behavior.

Rules that toggle the natural spawning of various mobs and entities.

Rules related to the world environment, including time progression, weather cycles, and fluid dynamics.

Game rules that are specific to Bedrock Edition and do not have direct equivalents in Java Edition.
