Game Rules Mod (1.21.7, 1.21.1) gives players the freedom to adjust Minecraft’s built-in game rules at any point during gameplay, even after a world has been created. In vanilla Minecraft, game rules can only be set before world creation or through commands this mod bypasses that limitation by adding a convenient GUI accessible with a customizable keybind.

Ideal for players who want to fine-tune game behavior (like mob griefing, fire spread, daylight cycle, etc.) without switching to creative or enabling cheats, this mod brings flexibility and convenience to both singleplayer survival and custom game setups.
