Starsown is a free browser game about growing worlds that have never existed. Press SOW and a planet blooms from a 128-bit seed - one of 340 undecillion possibilities - with your name on its discovery, forever.
Claim the worlds you find, stake a claim on the ones others left, and watch rare finds and firsts become permanent history in a sky sown by everyone.
Starsown needs JavaScript to draw the sky. Meanwhile: how to play · the science library · about.
