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?

i have to say : it did not really click. The game throws a lot of information at you right at the start, and i had a hard time to understand "what it wants from me". The UI is kind of clean, but there is too much information there for someone starting the game. Usually with these type of games, you get either hooked very fast, or not at all. Unfortunatly i am second. So i can´r really recommend it. from my point of view PS : regarding the strange AI hate reviews : I dont get the problem? EVERY developer ( even tripple AAA Studius) is using AI in some form, why wouldn´´t they ? it is a great tool that takes away workload, and allows SoloDevs or very Small Teams to do stuff besides their full time job. I really can not see how this makes a game worse, just because AI was used. Neither is not using AI making a good game... And especially i can not understand why ANYONE would "stalk" a developers postings or whatever somewhere in the net to "prove AI was used"... do you not have better things to do in your life? :D
I desire to feed my boy, my poor lad is so hungry. He must consume. CONSUME MY SON! CONSUME the very COSMOS!

its peak, i hold click, black hole get bigger, i reset and it get even bigger
Upgrade interactions are inconsitent and sloppy. After the last patch, the discounts you get for upgrading different black hole upgrades stopped working and still hasn't been fixed. My last run I was 28 light years in diameter and sitting at around 50-200% disc pressure, when I decided to remove a few levels out of compression to be safe before upgrading feed levels. Even though my limit before forced collapse was close to 500% disk pressure, immediately after removing a few levels (which should decrease pressure) my pressure jumped up to over 500% and the blackhole collapsed, ruining my run. Don't waste your money on this trash.
Quote from game description: [b]Compete globally or against your friends to achieve the biggest black hole. Maybe you'll be #1.[/b] Forget about it, when u spend a whole afternoon playing this game the server says F your run and u won't compete for the leadboards. I'll perfect the game and never touch it again.
AI slop, the different resources/currencies make little to no sense, upgrades are legit just useless or can slow your progress (!!!), not recommended.
my big black hole is massive and it sucks everything in
slop
After 50 hours, this game has been so much fun. It is unique to other idle games in the way it requires strategy. If you want your black hole to grow while idle, you better make sure there's no way your feeds will make it collapse. This gives you options: do you want to farm collapses to permanently strengthen your stats? You can set that up by turning on auto-buy and auto-collapse. Do you want to really grow and move up the leaderboard? There will be trial and error, but you'll figure it out. Overall, the game is a 10/10. Visuals are great and props to the developer for being so active with the community through the discord. I'm glad knowing the dev is keeping up with the feedback and working on making the game even better. How to Grow a Black Hole has been a breath of fresh air for me; I normally play competitive fps, but it's nice to have a game I can play that's not so stressful for once! Thanks Noah, great job and keep it up!
I am not sure it is worth four bucks. The game lacks explanation of zillion parameters that you upgrade; you get that they are somewhat different, but eventually just raise them all evenly and keep the feeding sources moderately upgraded to provide the "below threshold" level. I still scientifically do not get why the black hole collapses; but hell with that, just do not overfeed it :). Once you get this trick, the game just plays itself. This is a very raw skeleton of a potentially interesting game.
