About Three Suns

Three Suns is a physics survival game that puts you in charge of the last living world in a chaotic three-sun system. You place gravity anchors to steer the planet's path and switch between survival modes as conditions change, trying to last through one punishing dawn after another.

The setup draws on the three-body problem from orbital mechanics and on Liu Cixin's novel The Three-Body Problem, though the story, mechanics, and world are the creator's own. ChatGPT and Three.js were the tools behind it, and it finished 217th of 945 in Vibe Jam 2026. Phones are supported too.

There is no steady orbit to settle into. Survival depends on reading how the suns pull on the planet and answering with well-timed anchor placement, dawn after dawn.
