Minecraft seed map: structures and slime chunks
Explore any seed on the map
Enter a world seed to reveal slime chunks and structure locations — villages, monuments, mansions, outposts, ancient cities, trial chambers, abandoned camps (26.3 worlds) and more. Drag to pan, scroll to zoom, toggle any layer.

Structure markers are placement candidates from Minecraft's region algorithm (Java 26.3): the exact chunks the game tries in each region. Slime chunks are exact. Pillager outposts already pass the game's 1-in-5 roll and its rule against any village candidate within 10 chunks. Every structure still needs a suitable biome to generate, which the map doesn't check yet. Strongholds show the inner ring's three positions before the game shifts each one, by up to 112 blocks on each axis, into a suitable biome.
Seed map questions
- Where do I find my world seed?
- In an existing world, open the chat and run /seed — it prints the number. When creating a world you can type your own seed into the Seed field, and anyone using that same seed on the same Minecraft version gets an identical world.
- What is a slime chunk?
- Slimes spawn naturally below Y=40 in roughly one chunk in ten, chosen by a hash of the world seed and the chunk coordinates. Those chunks are fixed for the life of the world, which is what makes them worth mapping before you build a slime farm.
- Do the structure locations match my actual world?
- The markers come from the game's own placement math for your seed and the version you pick: they are the chunks where the game tries each structure, and pillager outposts already pass the game's 1-in-5 roll and its no-village-within-10-chunks rule. Not every try succeeds. The game also checks the biome, which the map doesn't yet, so a village marker out at sea stays empty. Strongholds are drawn where the game starts looking, before it shifts each one up to 112 blocks into a suitable biome. Use the coordinates as a strong starting point rather than a guarantee.
- Does this work for Bedrock seeds?
- The map follows Java Edition generation. Bedrock uses a different generator, so the same seed number produces a different world there and the structure positions shown here will not line up.
