7 Days to Die Seeds: How to Find a Good World Seed on V3

We also explain which settings matter, how to put a seed on a dedicated server, and what to send your friends so everyone gets the same world.

Last updated 9 October 2026. Checked against 7 Days to Die V3.3.0 (released 5 October 2026).

Why old 7 Days to Die seed lists don't work any more

A seed on its own doesn't describe a map. It is an input: the same seed, the same world size and the same version of the generator give you the same world. Change any one of the three and the map changes.

Running the world on a server? Our 7 Days to Die server guide covers world settings, sandbox presets, crossplay and backups.

The generator has changed more than once. The official V3.0 "Dead Hot Summer" release notes list a new district creation algorithm, a new biome layout called "Circle 2" that doubles each biome, a town planner that now tries a smaller town with tighter space rules when a normal one doesn't fit, and two new tile variants for 100x100 commercial and industrial points of interest (POIs). The same notes mention reduced rural tile percentages and many more tweaks.

So a seed that gave a big city next to a trader in Alpha 21 will give you something else today. Our earlier version of this page listed named Alpha 21 seeds such as "Blackjack", "Nameloc" and "Afterlife". We have removed them: we can't confirm what they generate on V3.3.0, and we would rather say so than send you into a new world expecting the old one.

How to pick a good seed for 7 Days to Die V3

Generate a few worlds and judge them yourself. In the V3.0 notes the game now has a world generation previewer with a Generate World button (it turns into Cancel while it runs), a terrain preview step, and a biome preview that appears as soon as it is generated. Use it to look at a map before you commit a save to it.

Things worth checking in the preview:

• Biome spread. Biomes decide how hard the game gets, because the game has a biome game stage and biome progression (both appear in the V3.0 notes). Check that your start area isn't boxed in by the harshest biome, and that the others are within reach.
• Traders. Quests and trading are your main progression loop early on. Look for a trader within a sensible walk of your start and a few more spread across the map, rather than all of them in one corner.
• Towns and cities. Loot sits in POIs, so a world with a mix of small towns and at least a few large cities gives you something to do in every stage.
• Roads and water. Roads make long trips quicker, and rivers and lakes make good base spots. If you can see a clear road link between your start and the nearest trader, that helps new players.
• World size. The usual choices are 6K, 8K and 10K. A bigger world has more room and takes longer to generate, download and explore, so a small group usually does fine on the smaller sizes.

Pick one of the sizes, try a handful of seeds with a theme (your own name, a word your group likes, anything), and note the ones that look right. If the map is not what you hoped, change a character and generate again.

Setting a seed in a single-player or hosted game

1. Start a new game and pick the random world option instead of Navezgane, the hand-made map.
2. Type your seed into the seed field and choose your world size.
3. Generate and look at the preview, then start the game.

Navezgane is a fixed map, so the seed field does nothing there. If you would rather learn the hand-made map first, we have a Navezgane map guide.

V3.0 also added 150 sandbox customisation options, so how hard the game is depends far more on those settings than on your seed.

Putting a seed on a dedicated server

On a dedicated server the world comes from serverconfig.xml. Three properties matter:

• GameWorld set to RWG for a random world (or Navezgane for the fixed map).
• WorldGenSeed, your seed text. It is only used when GameWorld is RWG.
• WorldGenSize, the world size.

The server generates the world the first time it starts, then keeps it, so changing the seed later means a new world, not a rewrite of the old one. Back up your save before you change anything. The V3.0 notes also say the older difficulty properties were folded into a single SandboxCode property, so don't copy a config from an Alpha 21 guide without checking it.

On a GTX 7 Days to Die server you get full access to the config, so you can set the world type, seed and size yourself, or upload a world you've already generated or downloaded.

Sharing a seed with friends

If you play with others, tell them three things, not just the seed: the seed text, the world size and the game version (today V3.3.0). On a dedicated server nobody has to type the seed, because players download the world from the server when they join. Sharing the three values is for people who want to preview the same map before they join.

7 Days to Die seeds FAQ

What is the best 7 Days to Die seed right now?

There isn't a single best one. The best seed is the map that suits your group, and you only find it by generating a few and looking at the preview. Treat any "best seed" list from before V3.0 as a guess.

Do Alpha 21 seeds still work?

You can type them in, but the generator changed in V3.0, so they won't give the same map. Don't plan a base around an old screenshot.

Does the seed change the difficulty?

Not directly. Difficulty comes from your sandbox settings. The seed changes the shape of the map: where biomes sit, how towns are laid out and where traders are, and that can make an early game easier or harder.

Can I use a custom-made map instead of a seed?

Yes. Navezgane is the fixed built-in map, and you can load a downloaded or pre-generated world on a server. Whatever you use, test it on the version you run, because maps and mods are tied to game versions.
