Jigsaw blocks are technical blocks commonly used as a way to construct large structures from smaller sections.

Jigsaw blocks can be obtained by using the pick block control, or by using various commands such as /give @s jigsaw. In Java Edition, jigsaw blocks are also available in the Creative inventory when "Operator utilities" is turned on.

In Java Edition, structure pieces of jigsaw structures loaded using structure blocks or /place template include jigsaw blocks. Structures generated from clicking the "Generate" button in the Jigsaw block interface with the "Keep Jigsaw" setting turned on will also include jigsaw blocks.

In Bedrock Edition, structures placed using /place jigsaw or /place structure with keepJigsaws set to true include jigsaw blocks.

Jigsaw blocks do not naturally generate. Some structures rely on jigsaw blocks for generation (e.g. pillager outposts, villages, and ancient cities), but these jigsaw blocks are replaced by other blocks during generation.

Players in Survival mode cannot place jigsaw blocks.

Jigsaw blocks are function blocks used for the generation of jigsaw structures out of smaller templates.^[1] Jigsaw structures are used for the generation of pillager outposts, villages, bastion remnants, ancient cities, trail ruins, and trial chambers; other structures use hardcoded generation. The GUI of a jigsaw block can be used to configure its generation settings. Those are:

Target Pool

Refers to a template pool; or an alias of a template pool. The template pool is used to select the connecting structure piece.

Name

Name of the jigsaw block.

Defaults to minecraft:empty.

Target name

The desired name of the jigsaw block in the connecting piece to connect to this jigsaw block.

Defaults to minecraft:empty.

Turns into

What the jigsaw block turns into once the whole feature is generated.

Defaults to minecraft:air.

Selection Priority

Defines the order of jigsaw blocks in a template to generate the connecting piece. If the piece being generated contains multiple jigsaw blocks that are all valid connections to the parent block, the game tries to connect to the one with the highest Selection Priority first. In the case of a tie, the connecting block is selected randomly.

Placement Priority

Defines the order of in which the connecting piece is processed to handle its jigsaw blocks during the wider structure generation.

Joint type

Appears only when jigsaw block is placed facing up or down.

Contains two types of joints: Rollable and Aligned

• Rollable: The connecting piece is placed with a random rotation. Defaults to this.
• Aligned: The connecting piece is rotated such that the rotations of the jigsaw blocks match (marked by the white bar on the jigsaw block)

Jigsaw blocks can also be used to generate multiple levels of jigsaw blocks in the world. The settings in the 2nd to last row are only used for this purpose and are not saved when leaving the UI.

Levels

Determines how many jigsaw block "levels" it goes through. (ex. Piece>[Layer 1]>[Layer 2]).

Can be set to an integer from 0 to 20. Defaults to 0.

Keep Jigsaw

Determines if the placed pieces includes the jigsaw blocks it contains or become what its "Turns into" field is set to.

Defaults to ON

Generate

The button to start the generation.

Jigsaw blocks cannot be pushed by pistons. They also cannot be pushed nor pulled by sticky pistons.
