Minecraft seeds that create dungeons close to where a player spawns, meaning where they first enter the world, are on several websites, including Minecraftseeds.co, MinecraftWorldSeeds, and Minecraft Seeds. Seeds may work differently when used in different versions of Minecraft.
A Minecraft seed is a alphanumeric code associated with a Minecraft game save file. The program uses the code to generate a world, and players may share the seed in order to generate copies of that world on other computers or consoles. Because patches for Minecraft alter how a seed is used, the world generated from a seed in an earlier version may not look the same as a world generated by that same seed in a later version.
