How to Find Slimes and Make a Slime Farm in Minecraft

The 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. But all of these uses are only discoverable if you know how and where to find slimes in Minecraft. Moreover, if you know how to make a slime farm, then you can have a constant supply of food for frogs in Minecraft 1.19. As you will see, the former part isn’t as hard as finding mobs like axolotls in Minecraft. 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.

Make a Slime Farm in Minecraft (2023)

We will first cover the spawn point of slimes, followed by their storage and farming process. If you already know how to find and get slimes in Minecraft, you can directly skip to the farming process.

What is a Slime in Minecraft

Slimes are unique hostile mobs in Minecraft that are cube-shaped and bouncy. They spawn in underground areas of specific chunks within your world or in a few chosen biomes. You can find slimes in three different sizes – big, small, and tiny. When a large slime dies, it breaks into small slimes, which upon killing break into tiny 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. However, one of the most popular uses of slimeballs is in creating sticky pistons, which are a useful component of various Redstone machines.

What are the Uses of Slimes

You can use slimes and slime farms in Minecraft for the following purposes:

  • To collect experience that gets dropped when a mob dies
  • For collecting slimeballs, which you can use to craft various items, including slime blocks, lead, and more.
  • Slimeballs also act as the main source of food for frogs, so you can use them to breed frogs in Minecraft.

Where Do Slimes Spawn in Minecraft

Above the ground, slimes most commonly spawn in the swamp and mangrove swamp 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.

What is a Slime Chunk

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. And the slime chunks are specific chunks of a Minecraft world, where the slimes can spawn underground. These chunks are rare and consist of only 10% of all in-game chunks. We will later 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 Minecraft biome except the mushroom fields.
  • The area in which slimes spawn must be below the world height of Y=40.
  • Unlike overworld slimes, the light and moon’s brightness don’t affect the underground slimes.

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 the creative mode.

How to Find Slimes and Slimeballs in Minecraft

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.

How to Locate a Slime Chunk

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 hack, 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 in Minecraft before selecting the area for the farm.

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.

2. Next, go to the slime finder website (visit) and paste the seed code in the seed column. 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.

3. 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 in Minecraft:

  • 64 torches or froglights or other light blocks (complete stack)
  • Multiple pickaxes with the best Minecraft enchantments
  • 256 cobblestone blocks (4 stacks of any building blocks)
  • 1 Allay with 2 Redstone repeaters, a note block, and 7 pieces of Redstone dust
  • 2 water buckets
  • 64 Magma blocks (complete stack)

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.

How to Make a Slime Farm in Minecraft

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

Create 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 opening you might discover to keep other hostile mobs away from your farm.

Create Mob Spawning Platforms

For our slime farm to work in Minecraft 1.19, 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 5 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 in your farm’s fit and to their 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.

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 Minecraft slime farm’s collection system.

Allay to Collect Slimeballs

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.

2. 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 in Minecraft.

3. 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.

4. 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.

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

5. 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.

Alternate Ways to Collect Slimeballs

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

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

All methods yield similar results in a Minecraft slime farm. You have to choose the one based on your resources and requirements.

How Does a 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 in Minecraft:

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

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

3. 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.

Make an Automatic Slime Farm in Minecraft

Some players work on bouncy Minecraft house ideas, while others create complex sticky piston machines with slimeballs. 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. But this is only one of the many survival farms you can make in the game. If you have a sweet tooth and want to collect honey, you can make a bee farm in Minecraft. Meanwhile, if you just want to collect XP, there is nothing better than a sculk farm in Minecraft.

However, no other farm comes close to the slime farm when it comes to dramatic performances. With that said, are you going to use Allay or stick with only a hopper in your Minecraft slime farm? Tell us in the comments below!


  1. I just wanted to note after my previous comment that honestly with the rates of this farm, even with the improvements I implemented, are far worse than those of a farm made in an actual swamp. Literally hunting slimes in a swamp is faster than this. It is still a good idea.

  2. I had noticed that not only was their “chunk” not 16 blocks wide, but also that they said the platforms needed to be 14×14 but in the image they are 11×11.
    A lot of info is left out, but There are some changes that I made from my own knowledge that improve the rates. It still only produces about 15 slimeballs per hour, but it’s better.
    You can mine out the chunk, make the platforms, and then you need to add mushrooms (brown and red work) on all blocks of the platforms besides in the center 4×4 (note: the platforms have to be 10×10 for how I made it.) It should look like a large square with a smaller square cutout in the middle.
    This will help, I promise. There is logic behind it involving light levels but it really doesn’t matter.
    After this, make a roof of tinted glass on top of the entire chunk. This will allow for enough light that they will still spawn, especially at night, while also not removing all light.
    That’s really all. I hope this helps. Also, if you can, light up all caves in the area to improve rates.

  3. If ur gonna go to the effort of mining a whole chunk for a slime farm, *please* don’t make this design. the spawning platforms are small, there is literally no reason to use an ally, hoppers or hopper minecarts work fine, and don’t be afraid of mining bellow y=10, it’s not likely you’ll find a warden. That being said, slimes don’t spawn in deep dark or mushroom fields, so don’t place your farm there.
