Void City io
About Void City io
Void City io is a free online io game where you control a growing black hole rolling through a bustling city, absorbing everything in your path. Cars, buildings, humans, lampposts — if it fits inside your void, it disappears into it, and your hole grows bigger with every object consumed. The catch is that other black holes are competing in the same city at the same time, and a hole larger than yours will swallow you whole. Stay aggressive, eat fast, and become the biggest void in the city before the timer runs out.
The game rewards momentum. A small hole in the early seconds needs to stick to people and small objects to grow quickly enough to compete. Once you reach a size where cars and small structures start disappearing into you, the growth rate accelerates dramatically. That tipping point — where you shift from hunting small prey to threatening the entire skyline — is what makes Void City io so satisfying to play.

Growing Your Void
Every object you absorb increases the diameter of your black hole. Small objects like pedestrians and bins give you a modest size boost in the early game, while vehicles, trees, and eventually entire buildings add significantly to your mass once you are large enough to consume them. Keeping track of your current size relative to the objects around you is key — attempting to absorb something too large simply bounces you off and wastes precious seconds.
Competing Against Other Holes
Void City io drops multiple black holes into the same city map simultaneously. Smaller holes are prey; larger ones are a threat. If an opposing void touches you and is bigger than your current size, you are absorbed and the round ends. Staying aware of where rival holes are on the map — and avoiding them until you outgrow them — is just as important as maximising your own absorption rate.
Tips for Void City io
Target dense clusters of people and small vehicles in the opening seconds to build size faster than opponents who chase isolated objects. Avoid rival black holes entirely in the early game — one unlucky collision ends your run before you have had a chance to grow. Once you are large enough to threaten buildings, head toward the most densely built sections of the map for the highest mass-per-second absorption rate. Check the scoreboard frequently to track which rivals are close to your size and need to be avoided or hunted.
