Minecraft Slime Chunk Finder (Java & Bedrock)
Enter your seed and position to see every slime chunk around you on a map, with the nearest ones listed. For seed -4172144997902289642 on Java, the closest slime chunk to 0, 0 is chunk 1, 0; on Bedrock (same for every world) it is chunk -1, 0.

| Chunk size | 16 × 16 blocks | 16 × 16 blocks |
How to use it
- Choose Java or Bedrock.
- Java only: type your world seed (use /seed in game, or read it from your world folder).
- Type your X and Z coordinates, or drag the map to move around.
- Pick a nearby green chunk and press Copy /tp, or walk there using the chunk's block range.
- Dig down below Y = 40 inside that chunk and build your slime farm.
How it works
On Java, the game decides whether a chunk is a slime chunk using the world seed and the chunk's coordinates in a fixed formula with Java's random number generator; this tool runs exactly the same formula. On Bedrock, slime chunks don't depend on the seed: they come from a different fixed formula using only the chunk coordinates, so every Bedrock world has them in the same places.
Questions
How do I know if I'm in a slime chunk?
Enter your seed and coordinates above: the yellow dot shows where you are, and green squares are slime chunks. On Java you can also press F3 + G to see chunk borders while you walk to one.
Why don't slimes spawn in my slime chunk?
Slimes from slime chunks only spawn below height Y = 40, need space and a spot to spawn on, and won't spawn when other mobs fill the mob cap. Light up caves around your farm and stand within range so the chunk is active.
Do I need my seed on Bedrock?
No. Bedrock slime chunks are the same in every world, so you only need your coordinates.
