3D .io game: grow your black hole in a neon city, swallow people, cars and towers, and devour the BOT holes!
About the game
Black Hole is a fast 3D .io game set in a neon city glowing under the night sky. You start as a tiny black hole; as you roam the streets, everything smaller than you tilts toward the edge, slides and spins down into the void. Capsule-shaped pedestrians, traffic cones, trash bins and streetlights are your first bites. As your mass grows the hole widens, the camera smoothly zooms out, and trees, parked and moving cars, buses and finally huge towers with glowing windows join the menu. Swallow several things of the same kind in a row and combo texts like +5 CARS fly up, and when a big building drops in the screen shakes. In CLASSIC mode every round lasts two minutes and you share the city with 8-12 named BOT black holes. A live leaderboard shows who is ahead. The rule is ruthless: a hole that is clearly bigger than you can swallow you too, while you can hunt down smaller BOTs. Finish the round in first place and you jump straight into a bigger, busier city with smarter BOTs, carrying part of your size with you as a starting bonus. SOLO mode has no rivals but the clock is ticking: you must swallow one hundred percent of the city, and an arrow on screen guides you to the last pieces. Spend the coins you earn on a larger starting size, more speed and longer rounds. Your progress is saved on your device. Free to play with no download or sign-up on phone, tablet and computer.
How to play

- Move over anything smaller than you: pedestrians, lamps, trees, cars, buses and buildings fall in.
- You grow with every bite; big objects and BOT holes can only be swallowed once you are big enough.
- CLASSIC: avoid bigger holes, eat smaller ones and be #1 when the 2 minutes end. SOLO: swallow 100% of the city before time runs out.
- Spend your coins in the ⚡ UPGRADE menu on start size, speed and round time.

FAQ
Are the other holes in Black Hole real players?
No. Every rival in CLASSIC mode is a computer hole marked BOT. Their number and intelligence grow with each new city; they flee bigger holes, hunt smaller ones and head for the richest areas.
What happens if I lose a round?
If you don't finish first, the ranking is shown. You can optionally watch an ad to replay the same city while keeping your size bonus; otherwise the game ends and Play Again restarts the same city. Your progress and coins are kept.
Does the game run smoothly on phones?
Yes. The city is built from low-poly models drawn in batches, and the resolution adapts automatically to your device's speed. It is designed to play smoothly even on mid-range phones.
