Generate Minecraft seeds packed with the most distinct biomes near spawn — the fast track to the Adventuring Time advancement. Each seed is ranked by how many different biomes appear within 1,500 blocks of the world spawn, computed with the same engine Minecraft Java uses.
Distinct biomes sampled within 1,500 blocks of spawn (Java 1.21). Ocean and cave biomes that reach sea level are included, as they all count toward Adventuring Time.
Click “Generate Seeds” to find biome-rich spawns
Click “View” on any seed to open it on the full map — zoomed out with the biome overlay so you can see every biome around spawn.
Open MC Seed View →Minecraft has dozens of biomes, and several advancements and challenges — most famously Adventuring Time — reward visiting many of them. On an average seed the biomes you need are scattered thousands of blocks apart. A biome-rich spawn packs a large variety close together, so you spend far less time travelling.
This finder scans random seeds, samples the biome on a grid within 1,500 blocks of the world spawn, and ranks each seed by how many distinct biomes it finds. The top results are the most diverse spawns — ideal starting points for a biome-hunting or advancement world.
The scan runs entirely in your browser using WebAssembly — no seed is ever sent to a server. Biome sampling uses the cubiomes world-generation library, so the biome layout matches Java Edition 1.21. A free, accurate alternative to Chunkbase.
