Village in an Ancient City
A village that has somehow ended up inside an Ancient City. If you can clear out the sculk shriekers without spawning the Warden, you'll have a peaceful underground hideout. Plus, there's an Amethyst Geode and a Mineshaft right above you!
Desert Temple at Bedrock
This desert seed hides a mind-blowing structure deep underground—a desert temple at Y-Level -54! Unfortunately, the chest loot is completely covered by bedrock, making it a mysterious yet frustrating discovery.
44-Diamond Ore Vein
Travel 14 million blocks to uncover one of the largest diamond veins ever found in Minecraft! This massive 44-diamond ore vein is an absolute jackpot for any survival world.
Triple Dungeon Spawner
XP grinders don't get better than this! Near spawn, you'll find a dungeon setup with two zombie spawners and one skeleton spawner—perfect for a mega XP farm. Nearby, there's also a mineshaft and a Trial Chamber waiting to be looted.
Village Inside a Mangrove Swamp
This isolated village sits right in the middle of a mangrove swamp, making it one of the rarest settlements in Minecraft. Even better, it generates a super rare swamp villager variant!
Zombified Village in the Lake
This eerie seed features an abandoned village built directly over a lake, making it look like a sunken ghost town. The surrounding cliffs and valleys provide the perfect location for a mega base.
Village in the Ocean
A fully functional village sits in the middle of the ocean, over 200 blocks away from land! This is a perfect survival island base, complete with an underground mineshaft and plenty of drowned mobs to turn into a Trident farm.
The Unbeatable Minecraft Seed
Due to a glitched End Island spawn, this is the only Minecraft 1.21 seed that is technically unbeatable. Once you defeat the Ender Dragon, the return portal doesn't generate, meaning you can never officially beat the game! (Patched in 1.21.2+)
Zombie Spawner Under Spawn
Be careful when you spawn in this world! Right beneath you is a surface-level zombie spawner. Nearby, you'll also find a Mesa biome with three cave spider spawners, making it an XP farm paradise.
Desert Temple with Village Inside
In this bizarre world generation glitch, a desert village and temple have merged, causing villager houses to be built inside the temple itself. It's a unique take on desert settlements!
Desert Temple with Outpost Inside
A Pillager Outpost has completely taken over a desert temple in this wild seed. Be careful if you decide to loot the structure—it's crawling with enemies! If you need a safe place, there's a village nearby to regroup.
Floating Island in the Sky
You spawn hundreds of blocks in the air on a floating island with only a few trees for survival. Luckily, there's an ocean below, allowing for an easy escape. This seed is perfect for a Skyblock-style challenge!
Bastion Inside a Nether Fortress
Two of the most dangerous Nether structures—Bastions and Nether Fortresses—have combined into one terrifying challenge. If you manage to survive, you'll be rewarded with insane loot and a perfect Nether Hub location.
Woodland Mansion Inside Lush Caves
This Woodland Mansion spawned inside a lush cave biome, making the eerie structure look like it's been reclaimed by nature. Underneath, you'll find a mineshaft and a Trial Chamber packed with loot.
Woodland Mansion Inside Pale Oak Valley
This stunning valley features a Woodland Mansion in the center, surrounded by lush hills and a rare Pale Garden biome. There are five different wood types within 100 blocks, making it an ideal location for builders.
Woodland Mansion in the Middle of the Ocean
One of the rarest structures ever found—a Woodland Mansion generated on a tiny 10x10 Dark Forest biome island, completely surrounded by ocean. Below the island, you'll also find a mineshaft, a Trial Chamber, and an Ocean Monument nearby!
Frequently Asked Questions
Do these seeds work on Minecraft Bedrock Edition?
These seeds are specifically for Minecraft Java Edition 1.21.4. While some seeds may generate similar worlds in Bedrock Edition, the exact structures and features will likely be different due to the different world generation algorithms between Java and Bedrock.
Will these seeds work in future Minecraft updates?
Minecraft's world generation can change between major updates. These seeds are guaranteed to work in version 1.21.4, but future updates (like 1.22) may alter terrain generation and structure placement. Minor updates within the 1.21.x series should maintain compatibility.
How do I find the coordinates in Minecraft?
Press F3 on Java Edition to open the debug screen which displays your current coordinates (X, Y, Z). Alternatively, you can enable coordinates in the game settings. For the Nether, divide overworld coordinates by 8 (except Y-coordinate).
What's new in Minecraft 1.21.4 world generation?
Minecraft 1.21.4 includes new Trial Chambers, improved cave generation, and tweaks to structure placement. The update also features new mobs like the Breeze and adds the Crafter block, which can be found in some of these seeds.
Which seed is best for survival mode?
For survival mode, we recommend seeds #4 (Triple Dungeon Spawner), #7 (Village in the Ocean), or #9 (Zombie Spawner Under Spawn). These provide good starting resources and interesting challenges without being too difficult.
