Build an Automatic Slime Farm in Minecraft: Endless Slimeballs for Redstone Projects

Slimes are probably one of the quirkiest monsters you can encounter in Minecraft. They are large, green blocks that bounce around and attack you. And when you attack them, they split into smaller versions! They have been present since the Alpha in Minecraft and always provide amusing moments. At the same time, it’s worth farming them because their slimeballs are an important resource for your constructions. Therefore, an automatic farm is a must and should also be present in your world.

The Best Uses for Slimeballs in Minecraft

If you work a lot with Redstone, slimeballs are probably one of your most important resources. But they are also needed for some other crafting recipes that you can take advantage of.

Crafting Tip: Make Sticky Pistons with Slimeballs

Sticky pistons are another form of pistons and are important for many Redstone projects. With them, you can not only push blocks away but also pull them back. This mechanic is used in some farms and machines and is therefore essential!

Slime Blocks in Minecraft: Useful Properties and Crafting Tips

From 9 slimeballs, you can create a full slime block. These look very similar to the monsters themselves and are slightly transparent. This makes them interesting as a decoration, but the block itself has some special properties. For instance, similar to a sticky piston, it can be used as a kind of glue. If there is a slime block between a normal piston and a block, it will be pulled and pushed.

On slime blocks, you can also reduce fall damage and, depending on the fall height, bounce like on a trampoline! This can have very amusing effects. Additionally, you can use full slime blocks to brew the “Potion of Slime,” which spawns two slimes upon your death.

Make Leads and Transport Animals More Easily

Leads are super handy when you want to move animals from one place to another. For the recipe, you also need slimeballs and some string from a spider. Make transporting livestock significantly easier! It’s always good to have a few leads on hand, just in case. By the way, you can also tie up your horse with it so it doesn’t run away.

Craft Magma Cream: Potions and Blocks from Slimeballs

You can get magma creams from the magma cubes in the Nether – the slimes of the underworld – but you can also craft them. Use blaze powder and slimeballs. From four magma creams, you can craft magma blocks. Additionally, you can brew potions of fire resistance with the cream, which are super useful!

Slimeballs for Frogs

Frogs are a new mob in Minecraft that you can also breed. Use slimeballs and feed them to the frogs to make them grow. Breeding works just like with normal livestock.

How to Build an Automatic Slime Farm in Minecraft

First, you need to know where exactly slimes spawn. This will determine where you want to build your farm.

• Swamp: Slimes spawn in swamps, but only between Y-level 51 and 69. The more advanced the moon phase is, the more slimes spawn.
• Slime Chunks: Depending on the seed, your world has various chunks (16x16 block sections) where slimes can appear at Y-level 40 or lower. You can hardly find these in the game, which is why we recommend Chunkbase. Use your seed and look for the green boxes there.

A wonderful help for building a slime farm is the ability to display chunk borders. However, this is only possible in the Java Edition. To do this, you have to press F3 and G simultaneously – and the lines will appear! Use these to guide you in the construction.

Interestingly, we need some blocks made from slimes for the construction of the farm. Therefore, it’s good if you already have a small stock of them.

Building Materials for the Slime Farm: Everything You Need

• Pickaxe (for excavation)
• 15 Magma Blocks
• Hopper + Chest
• Glass Pane
• Water Bucket
• 6 Slabs
• Lead
• Fence
• Torches
• 2 Snow Blocks + Carved Pumpkin

Building the Slime Farm: Step-by-Step Guide

First, find your slime chunk using the method we mentioned above. Either use the F3+G key combination and Chunkbase or just find the coordinates of the opposite corners and orient yourself by them. We will build the farm at Y-level 10 for maximum efficiency.

Excavate an area of 16x16 blocks with 3 blocks of height. You can line it according to your preference, or just leave the cave wall as it is. It’s up to you whether you want a beautiful or just a practical farm.

In the middle, you need to excavate a 4x4x4 trench, always 6 blocks away from all walls.

In the trench, slimes are automatically killed and their items collected. Line the floor with the 15 magma blocks, which inflict damage. Leave one corner free for the hopper, which leads to a chest in the wall. Enclose the chest with slabs so you can open it later. Place the glass pane on the hopper. Opposite the hopper, place your water, which will direct the slimeballs into the chest.

Now you need to create a way to attract the slimes. We use a snow golem, but an iron golem works too. Excavate a 6x6x4 block deep hole directly above the trench. In the middle, create a field from the 4 remaining slabs. Attach the fence to the ceiling above. Then build your snow golem with two snow blocks and a carved pumpkin and attach it to the fence with the lead.

The farm is essentially complete! Now, you just need to stand between 25 and 32 blocks away and wait for the spawns. A simple tunnel suffices. Make sure to light up all adjacent caves so no monsters spawn there, only in your farm.

Conclusion: Why an Automatic Slime Farm is Worth It

Slimeballs are one of your most important resources, especially for pistons and other Redstone adventures. Therefore, you should always have enough of them on hand. However, searching for slimes yourself is a challenging task, as they don’t spawn everywhere and swamps have become exceedingly rare. An automatic farm in a slime chunk is therefore the best option for you! Get unlimited slimeballs for your Redstone projects on your own server.
