Seed Finder for Slime Chunks
Specify which chunks near the origin should (green) or should not (red) be Slime Chunks, then search for seeds that match the pattern.
Warning: This tool was last updated for Minecraft 1.8 and uses the slime chunk algorithm from that version. It will **NOT** be accurate for modern Minecraft versions (1.18+).

Click chunks on the map below to set criteria, then press Start. Results will appear here.
Click on map chunks: Green = Must be Slime Chunk, Red = Must NOT be Slime Chunk, Grey = Don't Care.
How to Use
- Configure Chunks: Click chunks on the map above. Green means the chunk MUST be a slime chunk in the found seeds. Red means it must NOT be a slime chunk. Grey means you don't care about that chunk.
- Estimate Difficulty: Look at the "1 in X seeds match" estimate above the map. The higher X is, the longer the search will take.
- Adjust Settings: Use the sliders to set how many matching seeds you want to find and how many CPU "workers" (threads) to use for the search (more workers = faster search but higher CPU usage).
- Start Search: Click the "Start" button.
- View Results: Matching seeds will appear in the results panel as they are found.
- Control Search: Use Pause, Resume, or Stop as needed. Click "Edit Pattern" to modify your chunk selections (this stops the search). "Reset" clears everything.
- Explore Seed: Click on a seed in the results list to view its full slime chunk map in this tool.
Important: This tool uses the Minecraft 1.8 slime chunk algorithm. Seeds found here will only be accurate for that version range.
