Jigsaw Block

Jigsaw blocks are technical blocks in Minecraft, primarily used for the generation of larger structures. They do not generate naturally and are not available in the creative inventory. Players can obtain them using the pick block control or commands such as `/give @s jigsaw`. Jigsaw blocks are included when a player uses a structure block to spawn certain structures that utilize jigsaw blocks for generation. These blocks play a key role in the generation of structures like pillager outposts, villages, bastion remnants, and ancient cities. Each jigsaw block has a GUI interface that allows for configuration of generation settings. They work by connecting smaller structure templates to build larger structures, enabling the game to create diverse world landscapes in a modular fashion. Though they cannot be moved by pistons, jigsaw blocks are crucial for custom map making and modding, allowing players to design more complex generation rules.
