How to find Slimes and Slime Chunks in Minecraft

Slimes are a pretty rare mob in Minecraft. But they’re essential if you want to make some of the more complex contraptions in the game as they drop slimeballs. Slimeballs can be used to create sticky pistons and slime blocks.

To find slimes, you’ve got two options. First, slimes can spawn naturally below Y-level 40 in any biome. Slimes do not need darkness to spawn. Instead, they spawn based on something called a Slime Chunk.

For every chunk in Minecraft, there is a chance for a Slime Chunk to generate. Slime Chunks are generated during the spawn, and all chunks in the game have a one-in-nine chance to be a Slime Chunk.

You can search for Slime Chunks the old-fashioned way, by digging to lower than Y-level 40 and hoping for the best. Alternatively, you can use a slime finder site.

You can enter your world seed at a site like this, and it will work out which chunks in your world are Slime Chunks. From there, you’ll easily be able to find slimes.

The second way to find slimes is to head to a swamp biome. Slimes will naturally spawn in swamps, even if it isn’t a Slime Chunk. Slimes here will spawn between Y-level 50 and 70. 

With these two methods, you can easily find Slimes and Slime Chunks.
