About

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?

fun and relaxing. Great game for winding down after work!
Alright so over all it was pretty mid, the graphics were honestly pretty nice but most of the upgrades didnt seem to do very much to prolong your runs, maybe i was doing something wrong but it didnt seem to go anywhere. For almost all of the gameplay the game is 100% silent unless you got a achievement or start a new run. 4/10
i love this games idea but after you rebirth i think (i havent played this game in a month) its just not good, i bought this on release and i enjoyed the start but this game is boring. theres no reason to play more of it.

Very interesting game that plays exactly like any other rouge-style game, except with the unique mechanic of offline progression calculation. Extremely fun, as simple or difficult as you want it to be, and a great price.
peak
Excellent time sink, and I think the math checks out. 10/10, definitely recommend. Between the incredible visuals, the educational value, and the amazing soundtrack, this is a gem you should get today.
good idle farm
Симулятор, про то, как ты выращиваешь черную дыру, имба если честно, всем рекомендую
broken whenever i attempt to enter it works fine but every time i click the resume run it brings me back to steam fix this bug
This game is great, hope it gets more content over time. Amazing if you love space and incremental games.
