What Are Minecraft Seeds?

In Minecraft, a seed is a string of characters or numbers that the game uses to generate a unique world. Every world — including its biomes, terrain, structures, and spawn point — is created based on that seed value.

So, when you enter a specific seed, you’re telling Minecraft:
“Build a world using this exact blueprint.”

???? Example:

Entering the seed:
-9142863513851137753
…might spawn you right next to a village beside a desert temple and a jungle biome.
