About these 1.21.4 seeds

A swamp biome sample within 160 blocks of estimated spawn is required for every seed in this category. Lists are computed separately for the version printed on each card.

These lists retain the 1.21.4 generation model for older worlds and modpacks. Use 26.3 lists for Wilderness Bound; new biomes can change the same seed's layout.

Computed for Java 1.21.4. Spawn and terrain-dependent structure placement remain estimates.

For the current Java 26.3 release, see the main swamp seeds — or the same list for 26.3 · 1.20 · 1.19 · 1.18 · 1.16. All 1.21.4 lists live under best 1.21.4 seeds.

Frequently asked questions

How is this different from the main swamp seeds page?
These seeds are computed for Java 1.21.4. The main swamp seeds list targets Java 26.3. Match the version on the card; older versions can generate different biomes and structure positions.
Are these Wilderness Bound seeds?
No. These lists target Java 1.21.4; use the main catalog or the 26.3 lists for Wilderness Bound.
