Slime Spawner (2025)

FAQs

What are the requirements for slime to spawn in a spawner? ›

Spawning. Slimes spawn in the Overworld in specific "slime chunks" below layer 40, regardless of light levels. They can also spawn in swamp biomes between layers 51 and 69 (inclusive) in light levels of 7 or less, with these layers tending to be near the surface.

Slimes won't spawn if a player is within 24 blocks of the spawn area, and they will de-spawn if a player is 32 or more blocks away. Wait for a full moon. Slimes spawn most frequently during a full moon, so you may want to build a small shack with a bed nearby and wait for the full moon part of the cycle.

If no slimes at all are desired, then the world can simply be generated with a surface y level above 40, which will stop the slime spawns.

If no slimes at all are desired, then in Java Edition the world can simply be generated with a surface y level above 40, which stops the slime spawns. For details, see how to create custom world generation presets.

Slimes have unique rules when it comes to spawning; you can only find them naturally spawned in Swamp biomes. Slimes will spawn naturally at nighttime in swamp biomes (light level of seven or less), but they will be particularly plentiful if it happens to be a full moon.

Above the ground, slimes spawn in the swamp and mangrove swamp Minecraft biomes but only during the nighttime. Their spawn rate is affected by the following conditions: Slimes spawn most often under the full moon, and their spawn rate decreases as the moon fades away.

The best way to find Slime chunks reliable is to use a tool like Chunk Base. Input the name of the seed and the generator will mark Slime chunks automatically. Sometimes, players can also come across a Slime chunk naturally if they spot a Slime underground.

Slimes spawn in random underground chunks below Y=39 at any light level, and can also spawn in Swamp Biomes at night depending on the phase of the Moon. They spawn more frequently during a full Moon, and never spawn during a new Moon.

Yes they do. Slimes can spawn in any light level. The only things that affect slime spawning is the height level (i think they only spawn below y62, unless it's a swamp biome) and whether it's a slime chunk.

Because of the low altitude of the world, slimes spawn frequently.

Does carpet stop slimes from spawning? ›

Slime spawning in slime chunks ignore carpets, path blocks, and blocks filling their spawn radius. When there is something that slimes should not be able to spawn with depending on their spawn area restrictions, they should not be able to spawn. Slimes can spawn no matter what is in the way of the spawn chunk.

Spawning pads are usually constructed with a 2½-block gap using slabs, to allow all types of slimes to spawn. It is important to illuminate the spawn platforms a bit to allow slimes to spawn while preventing other hostile mobs from spawning.

Fences have a 1.5 block tall hitbox, meaning they cannot be jumped over by a player or mob, unless the mob is a horse, has Jump Boost, or is standing on a slab.

Slimeballs. Slimeballs are usually obtained by killing slimes. However, slimes don't spawn in peaceful difficulty.

Within slime chunks, slimes can spawn when Y < 40. This method requires an underground room to be dug out before the farm is constructed. Slime spawning in swamps can occur between Y=51 and Y=69.

You can summon a giant slime whenever you want using a cheat (game command) in Minecraft. This is done using the /summon command.
