How to Find Slimes and Make a Slime Farm in Minecraft

Slimes have been one of the most versatile mobs for a long time, and the Minecraft 1.19 update has only added to their glory. Now, they are a worthy enemy, a major part of Redstone mechanics, and even a great source of food for frogs. But all of these uses are only discoverable if you know how and where to find slimes. Moreover, if you know how to make a slime farm, then you can have a constant supply of food for frogs.

As you will see below, the former isn’t as hard as finding mobs like axolotls. But making a slime farm can be slightly challenging. So, let’s not waste time and learn the easiest methods to find slimes and make a slime farm in Minecraft.

How to Find Slimes and Make a Slime Farm in Minecraft

What are slimes in Minecraft?

Slimes are unique hostile mobs in Minecraft that are cube-shaped and bouncy. They spawn in underground areas of specific chunks or a couple of chosen biomes. You can find slimes in 3 different sizes – big, medium, and small. When a large slime dies, it breaks into medium slimes, which upon killing breaks into small slimes. The last and smallest type of slime drops slimeballs upon dying. You can use these slimeballs as a crafting ingredient for various types of recipes.

Where Do Slimes Spawn in Minecraft

Slime in Swamp Biomes -

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.
  • It can only spawn if the light level is less than 7 and the moonlight on that night is more than 0.

Slimes also spawn in slime chunks. A chunk in Minecraft is a 16 x 16 area of blocks on the horizontal axis. The whole world of Minecraft is divided into thousands of chunks. Slime chunks are specific chunks of a Minecraft world, where slimes can spawn underground. These chunks are rare and consist of only 10% of all in-game chunks. We cover the best ways to find these chunks and slimes in this guide. But finding the slime chunk isn’t enough. For a slime to spawn underground, the following conditions must also be met:

  • Slimes can spawn under any biome except the mushroom fields.
  • The area in which slimes spawn must be below the world height of Y=40.
  • Unlike the surface slimes, the light and moon’s brightness don’t affect the underground slimes.

How to Find Slimes and Get Slimeballs

The easiest way to find slimes is by visiting the swamp biomes at night and waiting for the slimes to spawn under the moonlight. But unfortunately, following this advice will only get you the slimes temporarily. If you want to make a slime farm, you must use underground slimes, which have a more reliable spawn rate.

And as you might expect, you must first find a slime chunk in your world for this to work. There are two methods to locate slime chunks in Minecraft – Exploration and Seed Analysis. Let’s go over each of them individually to find the best method for you.

1. Locate a Slime Chunk by Exploring

The simplest way to identify if a chunk can spawn slimes is by looking for slimes. Just dig down till you reach below Y=40 world height and keep exploring until you come across a naturally spawning slime. Once that happens, you have to wait around until you are sure that the area where the slimes are spawning is actually a slime chunk.

You can later use that specific chunk to create a slime farm. Moreover, as a little tip, you can use the “F3 + G” shortcut to make chunk borders visible in the Java edition. Unfortunately, there is no such feature on the Bedrock edition. You will have to wait around for slimes to spawn before selecting the area for the farm.

2. Locate a Slime Chunk with Seed Analysis

As you might expect, manual exploration is time-consuming and not the most efficient way to find slime chunks. Instead, you should spend some time analyzing your world’s seed and find out the slime chunks to reach them directly. Follow these steps below to analyze your world seed and find slime chunks:

  1. First, use the “/seed” command in the chat option to find the seed code of your world. This command works on both editions of the game. When the game displays the seed code, note it down. Make sure to also pen down the “-” sign if there is one in front of the seed code.

  1. Next, go to the slime finder website (visit) and paste the seed code in the seed option. Then, choose your game’s version from the drop-down below. The website will then analyze your seed and display the location of all the slime chunks.

  1. Finally, you can hover over the green boxes in the seed map to find slime chunks. Their coordinates will appear at the bottom left corner of the map. You should try to locate slime chunks closer to your spawn point to make the farm easier to build. The spawn point is indicated by intersecting purple lines.

Requirements to Make a Slime Farm in Minecraft

Once you locate a slime chunk, you need the following items to make a slime farm:

  • 2 Redstone repeaters
  • 7 pieces of Redstone dust
  • 1 Note block
  • 1 Allay
  • 2 Water buckets
  • 64 Magma blocks (complete stack)
  • 64 Torches, foglights, or other light source blocks (complete stack)
  • 256 Building blocks (4 stacks of any building block)
  • Multiple pickaxes

Almost everything you need for a slime farm is easy to obtain. However, you will need to spend some time exploring villages in your world to collect them in no time.

Make a Minecraft Slime Farm: A Step-by-Step Guide

With everything at your disposal, it’s time to start building an efficient slime farm. Make sure to follow the guide step-by-step in-game right now or bookmark it to avoid confusion. Let’s get started:

1. Create an Area for the Farm

To begin, you first need to dig out the entire slime chunk as deep as you can. We suggest you at least dig from Y=40 to Y=10 world height. If you go any lower, there’s a high chance that you might stumble upon the Warden, which isn’t a worthy risk. You can use TNT or pickaxes to get the job done. Just make sure to close any cave openings you might discover to keep other hostile mobs away from your farm.

2. Create Mob Spawning Platforms

For our slime farm to work, we first need to spawn slimes. For that, make two floating platforms with building blocks. The surface area of these platforms should be 14 x 14 blocks, and they should have a vertical gap of at least five blocks between them. To keep it simple, you can make one at Y=30 and the next at Y=25.

Moreover, there should be a gap of 3 blocks on all sides of the platforms. Doing so will allow the slime to slowly but surely jump into your farm’s fit and to its death. Moreover, replace some blocks of the platforms’ floor with froglight or similar light blocks. This will stop other hostile mobs from spawning on the platforms. The spawn rate of underground slimes isn’t affected by light level.

3. Set up the Killing System

Next, place magma blocks at the bottom of the slime chunk and cover the whole area to create a lava-like floor. The damage from magma blocks will kill the slimes and eventually make them drop slimeballs. Then, add a layer of water on top of these magma blocks as it will come in handy later in our slime farm’s collection system.

4. Allay Pick-Up System

Once everything else is ready, follow these steps to spawn slimes and get an Allay to collect slimeballs:

  1. First, you need to create a third floating platform a few blocks above the farm’s deadly floor. It’s not for the slimes, so you can make this one smaller in size.

  1. Then, place a note block on its edge. Later, when we play the note block, the Allay linked to it will make our slime farm automatic.

  1. Next, for our collection system to work, we need a storage area. For that, go beneath the new platform and place a hopper directly under the note block. Then surround it with three other hoppers, connecting each new hopper to the main one. Finally, place a chest underneath the main hopper.

  1. The note block must keep playing automatically to keep Allay linked to it. For that, you must place the redstone repeaters and the redstone dust in the following format. Make sure that repeaters in your farm are facing the same direction as the ones in the image.

  1. Then, bring your Allay to the note block and place a lever on the side of your note block.

  1. Finally, give a slimeball to your Allay by right-clicking or using the secondary action key. Now, activate the circuit by turning on the lever, but immediately break the lever as soon as you turn it on. By doing so, the Redstone circuit will be stuck on an infinite loop and keep playing the note block again and again.

5. Alternate Ways to Collect Slimeballs

If using Allay seems a bit complex, you can also use the following methods to collect slimeballs in your slime farm:

  • Hoppers chained on the floor of the farm
  • Water flow to transport slimeballs out of the farm
  • Hoppers in minecarts to collect and transport slimeballs

All of these methods yield similar results. You have to choose the one based on your resources and requirements.

6. How Does a Minecraft Slime Farm Work

Now that the structure is ready, it’s time to see your slime farm in action. Here’s how the slime farm will work:

  1. First, the slimes will spawn on the larger platforms and slowly but surely jump into the pit.

  1. Then, the magma blocks at the bottom of your farm’s pit will kill the slime and their smaller variants, leaving slimeballs behind.

  1. Finally, the Allay will pick up the slime balls and collect them all in the chest beneath the note block. The water on top of the magma blocks will protect Allay from taking any damage.

Whatever your plans might be, now that you know how to make a slime farm in Minecraft, you will never run out of slimeballs to feed your frogs in Minecraft. But it is only one of the many survival farms you can make in the game. Check out our guide on the best Minecraft farms and choose what you’re going to build next. With that said, what do you plan to do with so many slimeballs? Let us know in the comments below!

Can you breed slimes?

Unfortunately, there is no way to breed slimes in Minecraft. You have to make them spawn naturally for your farm to work. The only way around this mechanic is using a custom mob spawner, but you can’t do that without using cheats or being in creative mode.
