# Game rules

> Generated from the **26.3** decompile by `tools/gen_reference.py`. Do not edit by hand.

Every rule declared in `GameRules`, with its category (`GameRuleCategory`) and default. Integer rules list the bounds they declare after the default — a minimum always, a maximum only where one is not `Integer.MAX_VALUE` — and any feature gate. Values live in a `GameRuleMap` — a `SavedData` at *data/minecraft/game_rules.dat*, one set for the whole server rather than one per level. See [Level data and rules](level-data-and-rules).
