How To Grow a Black Hole is a chill incremental game about feeding, upgrading, researching, and barely controlling the most dangerous cosmic object imaginable.
Start small, feed your black hole, increase its mass, unlock new ways to grow, and push the numbers higher and higher until everything starts getting completely unreasonable. Just make sure things do not spiral too far out of control, because catastrophic collapses are very much part of the experience.
It is not a hardcore astrophysics simulator. It is a weird, satisfying, slightly stupid game about turning a tiny gravitational problem into an enormous one on purpose.
A little absurd. A little terrifying. Oddly hard to stop playing.
Feed your black hole and watch its mass climb.
Unlock upgrades that let you feed it faster, grow it larger, and push the numbers into ridiculous territory.
Research new systems to automate growth, improve efficiency, and keep the chaos moving.
Prevent catastrophic collapses when your black hole becomes a little too unstable.
Compare your black hole’s size and mass to real-world objects, which starts out interesting and gets unsettling fast.
Unlock bite-sized black hole facts, including why even a tiny one would be an unbelievable health hazard.
Compete globally or against friends to see who can grow the biggest black hole.
Hi, I’m Noah. I made this game in my free time because black holes are genuinely insane, and the idea of raising one like the world’s worst cosmic pet sounded too fun not to make.
I love games with giant numbers, satisfying progression, and simple ideas that slowly get out of hand. This started as one of those ideas that would not leave my brain alone, so I turned it into a real game.
I’m also hoping this project helps support the bigger and more ambitious games I want to make in the future. So by playing it, you are not just feeding a black hole. You are also helping me keep making games.
If you like incremental games, upgrades, research trees, leaderboards, cosmic horror treated a little too casually, and numbers that eventually stop feeling reasonable, this is probably for you.
If you are looking for strict realism and perfectly accurate astrophysics, this probably is not that. It is inspired by real black hole concepts, but mostly it is about making a cosmic problem worse because it feels good to watch the number go up.
How To Grow a Black Hole is a chill incremental game about feeding a black hole, keeping it stable, and trying to grow it bigger than everyone else’s. It is simple, strange, satisfying, and built around one important question:
How big can you make it before everything goes wrong?
