Puzzles Lib is a Minecraft Java Edition mod that provides a library API for other mods to use. It is intended for mod developers who need to create puzzle-related content. The name Puzzles Lib is a play on words, with the author suggesting that the reason for the name is itself a puzzle.
Puzzles Lib can be loaded using Fabric, Forge, or NeoForge loaders, and is used on both the client and server side. It is a required dependency for mods that utilize its library API, allowing developers to create and integrate puzzle-related features into their mods.
