Feed a black hole, push the numbers into absurd territory, and try not to let everything spiral out of control.
Overview
How big can you make it before everything goes wrong?
Feed your black hole, watch its mass climb, and unlock new ways to grow until the numbers stop feeling reasonable. It is not a hardcore astrophysics simulator. It is a weird, satisfying game about turning a tiny gravitational problem into an enormous one on purpose.
Compare your black hole's size to real-world objects, unlock bite-sized cosmic facts in the Codex, and compete globally or against friends to grow the biggest singularity. Just make sure things do not spiral too far out of control, because catastrophic collapses are very much part of the experience.
Features
What you'll be doing
Upgrade & automate
Unlock upgrades that feed faster and push growth into ridiculous territory. Research new systems to automate growth and keep the chaos moving.
Universal & Structural layers
Layer wide-effect Universal boosts with Structural upgrades that rewrite how rigs, emitters, and feed networks behave.
Prevent collapses
Push past disk pressure and trigger Accretion Collapse on your terms, or fail to keep things stable and watch a catastrophic collapse reset the run.
Codex & real-world scale
Persistent Codex facts, granular stats dashboards, and comparisons to real-world objects that start interesting and get unsettling fast.
Compete on Steam
Steam achievements, global and friends leaderboards, cloud saves, offline progress, and a free demo. Built for desktop launch.
