Slime Chunk Map
How Slime Chunks Work
- • About 1 in 10 chunks is a slime chunk, fixed forever by the world seed.
- • Inside one, slimes can spawn below Y 40 at any light level, in any Overworld biome except mushroom fields and deep dark.
- • Swamps and mangrove swamps also spawn slimes between Y 51 and 69 at light 7 or lower, most often on a full moon.
- • Peaceful difficulty stops all slime spawning.
- • For a farm, dig out the whole 16×16 chunk with several 3-high floors, light the surrounding caves, and AFK 24–128 blocks away.
Biomes & Structures
This map is calculated in your browser and only covers slime chunks. For biomes, villages, strongholds and other structures on the same seed, open it in Chunkbase:
Open seed in ChunkbaseFind slime chunks from your world seed
Roughly one chunk in ten is a slime chunk, and which ones they are depends only on your world seed. Paste the number from /seed and the map shows every one around you.
Enter your base's coordinates to see whether you're already standing in one, or get a list of the closest slime chunks with the centre block of each, ready to dig out.
The map runs entirely in your browser using the same formula as Java Edition, so it's instant and works for any seed.
Minecraft Seed Map & Slime Chunk Finder — FAQ
How do I find my world seed?
In singleplayer, or on a server where you're an operator, run /seed and paste the number exactly as shown, minus sign included.
Where do slimes spawn in a slime chunk?
Below Y 40, at any light level, as long as there's a solid block to spawn on.
Does this work for Bedrock Edition?
No. Bedrock slime chunks don't depend on the seed and use a different formula. This map follows the Java rules.
