About the Game
So what is
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.
What you actually do
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.
Why I made it
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.
Who it’s for
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.
Bottom line
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?

Version Information
Steam Patch Notes
Official update history
This small hotfix addresses a couple of issues reported after the latest update.
Fixed
Fixed feed source and black hole upgrades requiring a hold even for a single purchase. Clicking now buys one upgrade, while holding still works for rapid repeat purchases.
Fixed a rare startup issue where the game could hang on the GPU check screen. Restarting the game usually cleared it, but startup should now be more reliable.
Happy growing!
Startup, Display Settings Memory, and Graphics Compatibility
Thank you for the continued bug reports and startup feedback. This minor update focuses on improving desktop launch reliability, making startup progress clearer, and remembering your display setup between sessions.
Added
- Added a startup screen during desktop launch with load progress and recovery options if the game takes longer than expected to open.
- Added display settings memory for the desktop build. The game now remembers your window size, window position, selected monitor in windowed mode, and the monitor you last used for fullscreen.
Improved
- Improved hybrid-GPU startup behavior on laptops and multi-GPU systems.
- Added clearer automatic fallback behavior when the game detects a graphics mismatch.
- Added startup recovery actions, including copying diagnostics, opening the log folder, and relaunching in compatibility mode.
Fixed
- Fixed fullscreen and windowed preferences not always applying correctly after restarting the desktop build.
- Fixed blank or hung startup screens on some Windows setups.
Happy growing!
Fixed
Fixed an issue where feed sources "X AE required to unlock" would not update unless the user interacted with the game.
Fixed an issue where the info cards on upgrades would not update until the user hovered off and then hovered back over. Stats will now update in real time.
Fixed an issue with the research screen and progression page clipping out of the game while windowed.
Fixed an issue that would occur on very specific systems and cause bad screen tearing. This should now be resolved.
Tweaked
Added stat info to feed source upgrades, users can now see how much the next upgrade will improve the feed source.
Improved the visual of the research progress bar, it now looks much better.
Music now plays more frequently at random intervals between 8-28 seconds, instead of 45 seconds to 2 minutes. An option for continuous music will be included in the next update!
Added
Added the option to skip the collapse sequence by holding LMB.
Tweaked
Tweaked the survey to include a new question regarding purchasing the game.
Fixed
Fixed bug that caused the game to create ghost duplicate while alt-tabbing out of the game.
Tweaked
Reworked the collapse sequence visuals.
Improved performance significantly during heavy particle load, collapses, and UI overlays.
Fixed
Fixed an issue where the accretion disk could reset or disappear during collapses.
Fixed an issue where the black hole scene could freeze while the progression panel was open.
Added
Added a larger, scrollable Patch Notes view that can be opened from Settings.
Added company splash music support at launch.
Added a new splash sequence that fades from stars into warp speed, then reveals the black hole and game title.
Added two research upgrades: Feed Lane Controls and Reversible Upgrade Paths.
Fixed
Splash music now starts with the splash sequence in the Electron game shell instead of waiting for a click.
Collapse music no longer cuts off early. Tracks now play through with their intended fade.
Fixed upgrade row highlights that could stick after a purchase.
Fixed downgrade and sell pulses so they play on the correct action.
Fixed upgrade tier bar spacing and milestone labels.
Fixed upgrade affordability states so unaffordable upgrades are clearly dimmed.
Fixed the feed source cost reduction research info so it shows the full-stack discount instead of a source price.
Tweaked
Reworked research descriptions, effects, and improvement text so upgrades are easier to understand.
Improved splash title readability with a darker, blurrier overlay that eases into the live game scene.
Cleaned up Settings actions so Patch Notes lives with build info instead of the save/session controls.
The changelog, Welcome Back, and offline review modals now close with Escape.
Updated UI text across the game to be more consistent and easier to read.
