GuidesGuidesChoose a world seed, set level-seed before your world first generates, and understand why it only affects new worlds — plus how to read the seed of a world you already have.
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.

⚠️ 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).
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:
banana, 1234, your server's name. It generates a valid, repeatable world.level-seed before the first startThe clean way to start a brand-new server on a chosen seed:
level-seed (it's in the world-generation group).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.
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:
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.
Curious what seed built your current world — maybe to recreate it, or share it? Run this in the console or in-game:
/seed
It 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.
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.
level-seed. Seeds only apply to a world's first generation; make a new world instead (reset flow)./seed shows a different number than I set — same cause: your world generated before the seed was in place. Regenerate with the seed set first.
