Seed Finder
The Core Keeper seed finder helps you pick a good world seed before you start. Core Keeper worlds are generated deterministically from a hidden seed — biome rotation, boss spawn arcs and fixed scenes all depend on it, while terrain details are generated chunk-by-chunk as you explore.
How to use
Enter a numeric seed to jump to curated seeds with similar traits, or browse the full seed library by tag (starting / rich ore / boss-near / rare terrain).

What a seed controls
- Biome rotation — which direction Clay Caves / Forgotten Ruins sit, and the counter-clockwise order of the three outer biomes
- Boss spawn arcs — fixed-distance arcs with random angles for all main and optional bosses
- Fixed scenes — the Core, first-three-boss spawns and NPC merchant scenes
FAQ
- Does Core Keeper use seeds? Yes — every world is created from a hidden random seed that determines biome rotation and boss positions.
- Are seeds version-dependent? Yes. Major updates can change generation, so check the version tag on each seed page.
- Can I preview terrain from a seed? Not fully — terrain needs the game’s generation algorithm. This tool focuses on the deterministic high-level layout.
