Black Hole.io is an interesting multiplayer game where you control a black hole and compete against others.
The primary goal is to grow your black hole by swallowing objects in the environment, from small items like trash cans to entire buildings and even rival black holes.
You may move and feed several black holes throughout a metropolis in the Black Hole.io game. Move your hole by moving the cursor over it while holding down the left mouse button. If you let off of the button, the hole will end after following the path of your cursor. Eating as much as you can will allow you to keep growing. When the allotted time has passed or you are engulfed by another hole, the game will end.
To begin the Black Hole.io game, you must enter your name. Your hole will be tiny at first, and it can start eating anything it can fit. If you have a large enough hole, you can eat almost anything in the city, including people and structures. Your hole will get bigger after you reach a specific amount. As you eat objects, numerals will appear that indicate their value. This will allow you to consume larger items, such as smaller holes. You'll get swallowed if you find yourself in the middle of a hole larger than yourself. Based on how much you consumed, you will be given a score at the end of the Black Hole.io game.
