Version support & accuracy
Java 1.20.6, 1.21.1 and 1.21.3: Overworld, Nether and End. Trial chambers require 1.21. Some structures are biome-checked candidates; mineshafts show placement candidates.
Biomes, villages, strongholds and slime chunks are algorithmic predictions, checked by automated regression and limited published references. Broad in-game validation has not been completed. Natural terrain uses estimated elevation and shading, not individual terrain blocks; biome-color mode samples Y=63. Spawn is estimated, and structures do not include Y.

Less wandering. More wondering.
This map starts in the Overworld with the igloo layer enabled. Enter your seed and the version that generated the area, then inspect candidate locations and share your map.
Available versions, dimensions and layers are listed in the map controls. Structure candidates do not guarantee complete generation, and terrain heights are estimates. Read about support and accuracy
Bring your seed
Copy the full seed from /seed and choose the Java version that generated your world.
Find your next stop
Switch between natural terrain and biome colors, follow a river, and pick a village or stronghold. Terrain heights are estimated.
Take the coordinates
Copy X/Z coordinates or save a map link to come back to the same view.
Before you set out
A few things worth knowing about your world.
Which versions support igloo predictions?
Available for Java 1.20.6, 1.21.1, 1.21.3 in the corresponding dimension. Chunks generated before a world upgrade retain their original generation rules.
Does a marker guarantee that the structure exists?
Candidate positions pass biome checks, but the tool does not simulate complete block generation or terrain viability. Results do not guarantee a structure, locate its loot or rooms, or supply a height.
How do I use coordinates in the Overworld?
Copy X/Z and check the same dimension, seed and generation version in game. The tool does not calculate a safe standing height; inspect the actual terrain before teleporting.
