Seed map

Minecraft speedrun seeds (Java 26.3)

Everything a run needs, close by: a ruined portal within 160 blocks of the spawn; in the Nether, from the spawn’s point there (its coordinates divided by 8), a fortress within 160 blocks and a bastion within 240; and a stronghold within 1,000 blocks.

Java Edition 26.3 only: since 1.18 a seed gives the same terrain in Bedrock, but Bedrock places its structures elsewhere.

How these seeds were found

Every seed here was found by our seed map’s own generator (cubiomes, for Minecraft Java 26.3): seeds drawn from a fixed sequence, each tested against what its list promises, none copied from another list. Distances run across the ground, from the spawn to where the game starts each structure.

29 of the 480,000 seeds tested pass this list’s test: the 8 here come closest to it, and no seed is on two lists.

Each picture covers 1,024 by 1,024 blocks centred on the spawn: biomes in the seed map’s colours, the spawn as a white cross, each structure as a square of the colour beside its name.

The spawn is an estimate: the game then looks for grass nearby, so a player may appear a few blocks away.

Seeds found with cubiomes (xpple/cubiomes, commit 18edd56) for Minecraft Java 26.3, the generator of our seed map.
