Seedworld: Tend a Tiny World

Seedworld is a calm, co-op terrarium on a spinning planet. Gather two to four friends (or play solo), pass a hand of cards around, and tend a single world through one ten-minute epoch.

Each turn you play a card on the globe: Rain to fill the seas, Seed and Bloom to start life, Wind and Warm to shape the climate, Spark, Cool, Tide, Ice Age and Meteor when the world needs a shake. It is about watching what your choices grow.

An epoch moves through three ages. In the Age of Water, rivers and oceans settle. In the Age of Life, species appear, spread and get names. In the Age of Crisis, the world turns restless and what you built is tested. When the epoch ends you get a timelapse of the whole story and a report of every species you discovered.

Share your finished world as a link so friends can replay it, or fork it and tend it differently. Try the Daily World, where everyone starts from the same planet, and compare biodiversity on the leaderboard.

All art and audio are generated procedurally, and the simulation is deterministic: the same seed and the same cards always grow the same world.
