How to Use Game Rules in Minecraft: Complete Command Guide

Understanding Minecraft Game Rules

Game rules are powerful configuration options that allow you to modify your Minecraft server's gameplay without using mods or plugins. These built-in settings can dramatically change how your server functions, from basic gameplay mechanics to advanced server features.

Prerequisites

Before you can modify game rules:

You must have operator (OP) status on the server
Access to the server console or in-game commands
Basic understanding of Minecraft commands

Basic Game Rule Commands

To view all available game rules:

/gamerule

To check a specific game rule's current value:

/gamerule <ruleName>

To change a game rule:

/gamerule <ruleName> <value>

Essential Game Rules

Player Experience Rules

Keep Inventory

Controls whether players keep their items after death

/gamerule keepInventory <true|false>

true: Players keep all items when they die
false: Items drop on death (default)

Announce Advancements

Manages achievement announcements

/gamerule announceAdvancements <true|false>

true: Shows player achievements in chat
false: Silently awards achievements

Show Death Messages

Controls death notifications

/gamerule showDeathMessages <true|false>

true: Displays death messages in chat
false: Silently handles player deaths

World Behavior Rules

Daylight Cycle

Controls day/night cycle

/gamerule doDaylightCycle <true|false>

true: Normal day/night cycle
false: Freezes time at current position

Weather Cycle

Manages weather changes

/gamerule doWeatherCycle <true|false>

true: Normal weather changes
false: Locks current weather

Mob Spawning

Controls creature spawning

/gamerule doMobSpawning <true|false>

true: Mobs spawn normally
false: Prevents new mob spawning

Protection Rules

Mob Griefing

Controls mob environment interaction

/gamerule mobGriefing <true|false>

true: Mobs can modify blocks
false: Prevents mob block modification

PvP Combat

Manages player combat

/gamerule pvp <true|false>

true: Players can damage each other
false: Prevents player combat

On Minecraft 1.21.2 and later the pvp key was removed from server.properties, so this gamerule is the only way to toggle PvP. See How to Turn PvP On or Off on Your Minecraft Server for per-world setups and the older method.

TNT Explosions (Bedrock Edition only)

tntExplodes is a Bedrock gamerule. Java Edition does not have it, so a Java server answers "Unknown gamerule" if you try.

/gamerule tntExplodes <true|false>

true: TNT causes explosions (Bedrock only)
false: disables TNT explosions (Bedrock only)

On Java there is no gamerule for this. Use a protection plugin such as WorldGuard on Paper or Spigot instead.

Advanced Usage Tips

Combining Game Rules

Combine multiple rules for specific gameplay experiences:

Peaceful server: Disable PvP and mob griefing
Creative building: Disable weather and daylight cycles
Hardcore experience: Enable all damage-related rules

Performance Optimization

Three gamerules that genuinely cut server work:

/gamerule doMobSpawning false stops all new mob spawns, the single biggest saving on a busy world
/gamerule randomTickSpeed 1 (default is 3) cuts block ticking for crop growth, leaf decay, and fire spread. It slows farms, so treat it as a trade
/gamerule maxEntityCramming 8 (default is 24) culls entities that pile into one block, which is the real lever on entity processing

Common Configurations

Beginner-Friendly Server

/gamerule keepInventory true
/gamerule mobGriefing false
