Building 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 jump around and attack you. When you attack them, they split into smaller versions! They have been around since the Alpha version of Minecraft and always provide funny moments. At the same time, farming them is worthwhile because their slimeballs are an essential resource for your builds. Thus, an automatic farm is almost a necessity and should be present in your world.

The Best Uses for Slimeballs in Minecraft

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

Crafting Tip: Making Sticky Pistons with Slimeballs

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

Slime Blocks in Minecraft: Useful Properties and Crafting Tips

With 9 slimeballs, you can create a full block of slime. These look very similar to the monsters themselves and are slightly transparent. This makes them interesting as decoration, but the block itself also has some special properties. For example, it can be used as a sort of glue, similar to a sticky piston. If there is a slime block between a normal piston and another 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 a “Potion of Slime,” which spawns two slimes upon your death.

Crafting Leashes and Transporting Animals More Easily

Leashes are super practical if you want to move animals from one place to another. You also need slimeballs and some string from a spider for the recipe. Make transporting livestock much easier! It’s always good to have a few leashes on hand just in case. You can also use them to tie up your horse so it doesn’t run away.

Crafting Magma Cream: Potions and Blocks from Slimeballs

You can get magma cream from magma cubes in the Nether – the slimes of the underworld – but you can also craft it. Use blaze powder and slimeballs for this. With four magma creams, you can craft magma blocks. You can also 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 to feed them and 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 slimes actually spawn. This way, you can determine where you want to build your farm.

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

A wonderful help for building a slime farm is the ability to display chunk borders. However, this only works in the Java Edition. You need to press F3 and G simultaneously – and the lines will appear! Use these to orient yourself during construction.

Interestingly, we need some blocks made from slimes for building the farm. Therefore, it’s good if you already have a small supply 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 key combination F3+G and Chunkbase or just look for the coordinates of the opposite corners and orient yourself with them. We build the farm at Y-level 10 for maximum efficiency.

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

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

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

Now you need to create a way to lure the slimes. We use a snow golem, but an iron golem works too. Excavate a 6x6x4 deep hole directly above the trench. In the middle, lay a field of 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 post with the lead.

The farm is essentially complete! Now you just need to stand 25 to 32 blocks away and wait for the spawns. A simple tunnel is enough. It’s best to light up all nearby caves so that 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. You should always have enough on hand. However, searching for slimes yourself is a challenging task because they don’t spawn everywhere, and swamps have become exceedingly rare. An automatic farm in a slime chunk is the best option for you! Get infinite slimeballs for your Redstone projects on your own server. Rent your Minecraft server and get your machines running!
