Minecraft Slime Chunk Finder
By the ChunkScan Team · Updated October 2026
Quick answer: To find slime chunks, enter your Java world seed on this page and the map highlights every slime chunk around any coordinates; build the farm below Y=40 inside one. On Bedrock Edition slime chunks are identical in every world, so no seed is needed. Link straight to a result with /slime-finder?seed=YOUR_SEED.
Slimes spawn below Y=40 only inside specific chunks — about one chunk in ten. This slime chunk finder maps them for any seed, entirely in your browser, so your seed is never sent to a server. Java slime chunks depend on the world seed, so enter yours. Bedrock slime chunks are the same in every world, so no seed is needed. Looking for chunk borders and other structures too? Use the full chunk finder.

What is a slime chunk?
Slimes spawn naturally below Y=40 only inside slime chunks, which make up roughly one chunk in ten. They drop slimeballs — needed for sticky pistons, leads and magma cream — so a slime chunk near your base is the fastest route to an automated slimeball supply. A chunk is a 16x16 block column, so block 0 to 15 is chunk 0 and block -1 is chunk -1.
Are slime chunks the same on Java and Bedrock?
On Java Edition, slime chunks are determined by your world seed, so every world has them in different places — enter your seed to see yours. On Bedrock Edition, slime chunks are seed-independent: the same chunk coordinates are slime chunks in every Bedrock world, so you do not need your seed at all. A Java slime map will give a Bedrock player the wrong answer, which is the most common mistake with slime finders.
How do I build a slime farm?
A slime farm needs a flat, spawn-proofed area below Y=40 inside a slime chunk. Clusters of adjacent slime chunks are far more productive than a single chunk, because a larger contiguous floor spawns more slimes per cycle. “Slime cluster” under the map is the biggest cluster within 512 blocks of spawn; select it to jump there. To start a fresh world with a dense cluster near spawn, the seed search can filter for eight or more connected slime chunks.
