A seed is the number Minecraft uses to generate a world. The same seed always produces the same terrain, so a good seed means you get to choose your world — a spawn beside a village, a mushroom island, a huge cave — instead of taking whatever the game rolls. This guide shows you how to set a seed on Falix, and the one rule that trips everyone up: it only applies to a world that hasn't been generated yet.

First, the rule that saves you a headache
⚠️ Heads up: A seed only decides how a world is first generated. Setting
level-seedon a world that already exists does nothing — the terrain is already baked in. Seeds are a decision you make before the first start, or when you're creating a fresh world.
Keep that in mind and everything below makes sense. If you've already been playing and want a specific seed now, you're not editing a setting — you're making a new world (jump to Starting fresh on a chosen seed).
Picking a seed
A seed can be any number, or any word or phrase (Minecraft turns text into a number for you). You've got two ways to get one:
- Type your own —
banana,1234, your server's name. It generates a valid, repeatable world. - Grab a curated one — plenty of community seed sites collect seeds by what's near spawn (villages, biomes, structures) with screenshots. Search for "Minecraft seeds" and pick one that matches the map you want. Match the game version: a seed shown for one Minecraft version can generate different terrain on another, because world generation changes between versions. Use a seed on the version it was found on.
Set level-seed before the first start
The clean way to start a brand-new server on a chosen seed:
- Create the server but don't start it yet (no server? see the Java quickstart). If it already generated a world on a first boot, that world exists now — you'll want the fresh-world method below instead.
- Open the Properties page from your server menu and find
level-seed(it's in the world-generation group). - Paste in your seed and save.
- Start the server. Because there's no world yet, Minecraft generates one from your seed — same terrain everyone else got from that seed.
That's it. server-ip and server-port are managed by the panel and should never be touched, but everything else on the Properties page — including level-seed — is yours to set.
💡 Tip: Want a specific kind of world as well as a specific seed? The
level-typeproperty (same page) picks the generator — normal, flat (great for creative), large biomes, and amplified. Seed decides the layout; type decides the style.
Starting fresh on a chosen seed
Already have a world and want to switch to a new seed? You can't re-seed the existing world, so you generate a new one. Two clean options:
- The Worlds page generator. Open the Worlds page, generate a new world, and enter your seed (and world type) right there — no property editing needed. Full walkthrough in Manage your worlds.
- The reset recipe. Stop the server, rename or delete the old world folder, set
level-seed, and start — Minecraft builds a new world from the seed. The step-by-step (including renaming instead of deleting so you can go back) is the world reset flow.
💡 Tip: Whichever route you take, back up first if the current world matters — on the free plan, backups save to your own Google Drive. Re-seeding means a new world; the old one only survives if you kept it.
What seed is my world already on?
Curious what seed built your current world — maybe to recreate it, or share it? Run this in the console or in-game:
/seedIt prints the seed of the world that's loaded right now. That's a read-only lookup: it tells you the seed, it doesn't change anything.
Verify it worked
Start the server, join, and check spawn against what the seed promised — the village, biome, or landmark should be there. Still want proof it's the right seed? Run /seed and confirm the number matches the one you set. If spawn looks generic and /seed shows a random number, the world was generated before you set level-seed — generate a fresh one and set the seed first.
Troubleshooting
- My seed did nothing — the world already existed when you set
level-seed. Seeds only apply to a world's first generation; make a new world instead (reset flow). - The terrain doesn't match the screenshots — version mismatch. World generation differs between Minecraft versions; use the seed on the version it was found on.
/seedshows a different number than I set — same cause: your world generated before the seed was in place. Regenerate with the seed set first.
