You're standing in the dark. It’s that deep, blocky silence of a cave. Suddenly, a rhythmic clack-clack-clack of skeleton bones echoes from behind a mossy cobblestone wall. You've found it. But here’s the thing: most players think they can just pick that cage up and take it home. They can’t.
If you're wondering how do you make a monster spawner on minecraft, the answer is a bit of a "yes and no" situation. Technically, in survival mode, you cannot craft a spawner block. You can't mine it either—not even with a Silk Touch netherite pickaxe. It’ll just shatter into nothingness, leaving you with a handful of XP and a lot of regret.
What you can do is build a "natural" mob farm that acts like a spawner, or, if you're in Creative, use specific commands to manifest one. Most people are actually looking for a way to get endless loot—bones, arrows, gunpowder—without having to wander the plains at 3:00 AM.
The Hard Truth About Survival Spawners
Let’s be real for a second. Minecraft’s progression system is built around the idea that some things are fixed points in the world. Spawners are one of them. These 1x1 cages are found in Dungeons, Mineshafts, Strongholds, and Bastion Remnants.
Since you can't move them, the real trick isn't making the block; it's making a machine around the block.
Think of it like a wild animal. You can’t tame the cage, but you can build the cage bigger. When you find a zombie or skeleton spawner, you're looking at a goldmine. To activate it, you need to be within 16 blocks. If you stand too far away, the little spinning mob inside the cage stops moving. That’s your first clue that the farm is "off."
The Geometry of the Kill Chamber
Most players mess up the spacing. A spawner checks a 9x9x9 area around itself for valid spawning spots. If there are too many mobs of its own kind in that area, it just stops working. This is why "falling" designs are king.
You want to dig out the room. Four blocks out from every side of the spawner, and maybe three blocks above and below. Then, you use water. Minecraft water physics are weirdly predictable. A single bucket flows eight blocks. By placing water along one wall, you create a treadmill for the monsters. They spawn, they get pushed, and they drop into a hole.
Simple.

But wait. If you want a "manual" farm for XP, you need that drop to be exactly 22 blocks deep. Why? Because at 23 blocks, most mobs die instantly. At 22, they land with half a heart. You can punch them once with your bare hand, and boom—infinite levels.
How Do You Make a Monster Spawner on Minecraft in Creative?
Sometimes you just want to build a map. Or maybe you're tired of the grind. If you have "Cheats" enabled or you're in a Creative world, the rules of physics don't apply.
You won't find the spawner in the standard item menu. It’s hidden. To get it, you have to use the chat console. On Java Edition, you'd type something like /give @s minecraft:spawner. On Bedrock, it’s basically the same.
When you first place it, it’s a "Pig Spawner." Why pigs? Ask Mojang. It’s just the default. To change it, you don't need a PhD. You just need a Spawn Egg. If you want a Creeper spawner (which doesn't exist naturally in the wild), you grab a Creeper Spawn Egg and right-click the cage. The little pig inside will transform into a tiny, spinning Creeper.
Commands and Customization
For those who want to go deeper, the /setblock command is your best friend. You can actually customize how fast the mobs spawn. In the NBT data (the "brain" of the block), there are tags like MinSpawnDelay and MaxSpawnDelay.
Standard spawners wait anywhere from 200 to 799 ticks between spawns. That's a lot of waiting. If you set those numbers to 10, the cage will essentially explode with mobs. It’s chaotic. It’ll probably crash your game if you aren't careful. But it’s how professional map-makers create boss arenas.
Building a "Dark Room" Spawner from Scratch
If you're in Survival and you haven't found a dungeon yet, you have to build a "Dark Room" farm. This is the closest you'll get to actually making a spawner.
You’ve probably seen the giant cobblestone boxes in the sky on servers. Those are mob grinders. They rely on the game’s natural spawning algorithm rather than a physical cage block.
The Mechanic of Darkness
The game constantly tries to spawn monsters in a sphere around the player (between 24 and 128 blocks away). If you build a massive, pitch-black room high in the air, the game has nowhere else to put the mobs. It "forces" them into your trap.
- The Platform: Build a series of platforms inside a giant box.
- The Trapdoors: This is the pro tip. Mobs see open trapdoors as solid blocks. They try to walk across them and fall into the water canals below.
- The Height: Build this over a deep ocean. This prevents mobs from spawning in caves underground, which "speeds up" your farm upstairs.
Honestly, these are often better than cage-based spawners because you get a variety of loot. You’ll get string from spiders, gunpowder from creepers, and the occasional carrot from a zombie.
Why Your Spawner Might Not Be Working
It’s frustrating. You spent two hours hauling cobblestone, and nothing is happening.
First, check the light level. Since the 1.18 "Caves & Cliffs" update, hostile mobs only spawn in complete darkness (Light Level 0). Even a single stray soul torch or a crack in the wall will ruin the whole thing.
Second, check your "Mob Cap." If there are 70 mobs elsewhere in the loaded chunks—maybe in a dark cave 20 blocks under your feet—the game won't spawn any more. You have to light up every single cave in the vicinity. It’s a chore. It sucks. But it’s the only way to make a high-efficiency farm.

Third, slabs. Mobs can't spawn on "bottom" slabs. If you built your floor out of bottom-half slabs to save on materials, you've accidentally made a "mob-proof" room.
Ethics and Gameplay: To Farm or Not to Farm?
There’s a segment of the Minecraft community, often following the "Technical Minecraft" scene like the SciCraft guys or Ilmango, who treat spawners like industrial power plants. Then there are the purists.
The purists say that building a massive mob grinder ruins the "survival" feel. Why hunt for food when you have a machine that spits out cooked chicken and rotten flesh?
But honestly, once you've beaten the Ender Dragon for the tenth time, you stop wanting to hunt. You want to build. And building requires materials. Gunpowder for rockets (to fly your Elytra) is the biggest motivator. Without a "handmade" spawner, you're stuck walking. And nobody wants to walk in 2026.
Real-World Reference: The Technical Community
According to data and tests run by the Minecraft Wiki community and technical players, a well-optimized "General Mob Farm" can produce upwards of 5,000 items per hour. Compare that to a single Skeleton Spawner cage, which might give you 300-400 arrows in the same time.
If you're serious about the game, the "handmade" route is always superior to the "found" cage.
Essential Next Steps for Your Build
If you’re ready to stop reading and start digging, here is exactly what you should do right now to maximize your results.
Locate a Fortress or Dungeon Use an online tool like ChunkBase if you don't mind "spoiling" the seed. It will give you the exact coordinates of every spawner in your world. If you want to stay "legit," listen for sounds through walls. Subtitles (on Java Edition) are a literal cheat code here—they’ll show "Skeleton pops" or "Zombie groans" on the side of your screen with a directional arrow.
Clear the Perimeter Don't just build a box. Clear a 128-block radius around your AFK (Away From Keyboard) spot. If you don't want to dig, just build your farm 128 blocks above the ocean. This is the "lazy man’s" way to get perfect spawn rates because the game won't find any other spots for mobs to appear.
Automate the Kill Use a campfire. If you place a soul campfire at the bottom of your drop chute, it will kill the mobs slowly without destroying the items. Put a Hopper underneath the campfire, and the loot will go straight into a chest. You can go to sleep in real life and wake up to a chest full of loot.
Manage Your XP If you use the campfire method, you lose the experience points. If you want the levels, you have to be the one to deal the final blow. Use a "Sweeping Edge" enchanted sword to clear out the mobs in batches.
The mechanics of Minecraft are deep, but they are consistent. Once you understand that "making" a spawner is really about managing light levels and mob caps, you stop playing the game and start running it. Get your torches ready, find a cave, and start clearing that 9x9 space. Your infinite supply of gunpowder is waiting.
