One seed, one world
A world is made from a seed and a handful of settings, and nothing else. The same seed gives the same continent on your laptop, your phone and anybody else's, down to the last river bend.

Type a seed and a world grows in front of you: mountains raised and worn down by water, rivers that find their way to the sea, climates, forests and deserts, and towns where people would choose to live. Then fly over it, from the whole continent down to a single valley.

How it works
A world is made from a seed and a handful of settings, and nothing else. The same seed gives the same continent on your laptop, your phone and anybody else's, down to the last river bend.
Land is raised and worn down by water, rivers gather where the rain flows, climates follow latitude and mountains, and cities grow where the land is good, linked by the cheapest roads across it.
Zoom in and the land keeps its promises: finer hills, villages and lanes are made as you look, and they always fit the continent around them.
