Sunborn

Every star starts as a spark. Grow yours until it goes SUPERNOVA, and build a machine that grows it for you.

Start As A Spark

Drag fuel into a tiny Protostar by hand. Every orb you land makes it bigger. Then start automating: upgrades pull dust in on their own, so your star keeps growing even when you let go.

158 Upgrades. Automate Your Growth.

Four constellations in the Stellar Nexus. Every upgrade stacks on the last, until your star feeds itself.

Ignite Through Every Stage

Protostar. Red Dwarf. Yellow Sun. Blue Giant. Red Giant. Every ignition makes your star bigger, brighter and hungrier, and your numbers climb from single digits into the billions.

Build A Stellar Machine

Nebula Drift, solar winds, pulsation rings: stack enough and your star harvests on its own. Play active, idle or both.

Survive Titanic Events

A rogue planet is on a collision course with your star. Ram it with orbs before it hits, then shatter it for a jackpot. The full game adds more titanic events.

Go SUPERNOVA

The moment every run builds to.

Three Ways To Play

Standard: grow at your own pace. Sprint: 15 minutes, race the clock. Astral Shield: save a dying star. Four global leaderboards.
