Game rules allow server administrators to refine the logic and mechanics that govern a Minecraft world. These settings control specific elements, such as whether fire spreads, how mobs behave, or if players keep items after death. Operators adjust these variables to tailor the environment to a preferred difficulty level or gameplay style. The modifications take effect instantly, updating the global state without requiring a server reboot.

Note: Game rules are case-sensitive.
The settings listed are default as of Minecraft version 1.21.9.
