A double helix of DNA wound around a living planet

The core of the game

Every empire grows from its genes

Genes shape traits. Each world tests them with its climate, each caste with its work. Work feeds the economy and the army, the economy pays for science, science opens the Genome Lab — and the lab creates new genes. Your empire is genes × planets × technology.

What you do

A whole civilization in your hands

Genetics at the core

24 gene families, mutations and hidden side effects. What thrives on a frozen world starves on a desert planet.

Colonies that live

Workers, food, science and materials flow from the creatures you bred. Hungry creatures work worse; a well-fitted caste carries the colony.

Hunt for genes

Every planet has its own plants and animals. Take a sample, read its DNA, work out what each gene does and splice the one you want.

A shared galaxy

Send scouts, settle systems, contest territory and trade genes and goods with other players on a live market.

Diplomacy and war

Treaties need consent, allies see each other's fleets and invade together, and wars end in peace or ruin. Design ships from hulls and modules and defend your domes.

Six paths to victory

Win by military might, technology, economy, culture, megaprojects or the ascension of your species. Each path has its own goals and its own standings.

Living worlds

No two creatures are alike

Every creature is grown from its genome: body plan, limbs, eyes, color and gear come from its DNA, not from a list of skins. These are drawn by the game itself.

In the game

Screens from the game

Captured in a running test world after four hundred turns.

On the phone

Your empire in your pocket

The same world fits a phone screen: play in the mobile browser today; a native iOS app is on its way. The world runs on the server, so your colony lives on while you are away.

How it is built

Solid engineering under the hood

One deterministic core

The rules are written once in Rust and run on the server. The browser uses the same Rust code, compiled to WebAssembly, to grow creatures from their genes and read the live channel.

A world that never sleeps

One main server per world checks every order and keeps the world running while you are away.

Built for scale

Tested with a thousand players in one world and designed for ten thousand, over a live WebSocket channel.

Private by default
