Version support & accuracy
Java 1.20.6, 1.21.1 and 1.21.3: Overworld, Nether and End. Trial chambers require 1.21. Some structures are biome-checked candidates; mineshafts show placement candidates.
Biomes, villages, strongholds and slime chunks are algorithmic predictions, checked by automated regression and limited published references. Broad in-game validation has not been completed. Natural terrain uses estimated elevation and shading, not individual terrain blocks; biome-color mode samples Y=63. Spawn is estimated, and structures do not include Y.

Less wandering. More wondering.
Find the right chunk before you dig. Slime chunks are drawn as a separate overlay, with boundaries aligned to Minecraft’s 16-by-16 block grid.
Available versions, dimensions and layers are listed in the map controls. Structure candidates do not guarantee complete generation, and terrain heights are estimates. Read about support and accuracy
Bring your seed
Copy the full seed from /seed and choose the Java version that generated your world.
Find your next stop
Switch between natural terrain and biome colors, follow a river, and pick a village or stronghold. Terrain heights are estimated.
Take the coordinates
Copy X/Z coordinates or save a map link to come back to the same view.
Before you set out
A few things worth knowing about your world.
Will slimes always spawn in these chunks?
No. A slime chunk is one requirement; height, space, player distance and other game spawning rules still apply. This layer does not simulate mob spawning.
How are negative coordinates handled?
Chunk coordinates use floor division by 16. For example, block X=-1 belongs to chunk X=-1, not chunk zero.
Does this work for Bedrock?
Select Java or Bedrock in the edition control. Slime chunk rules differ by edition, so never use a Java overlay as a Bedrock result. Check the experimental status and supported version shown for Bedrock.
