What’s Inside
Absorb and Expand
Vacuum.io places players in a tiled field where you pull in loose matter and smaller opponents to grow your mass and push up the leaderboard.
- Your vacuum radius increases as your mass grows, pulling in nearby objects passively
- Smaller players caught inside your radius are absorbed without a direct collision requirement
- The field continuously spawns new matter to keep growth opportunities distributed across the arena
Size-Based Hierarchy
The arena operates on a strict size ladder — you absorb anything smaller and must avoid anything larger until you can close the gap.
- Visual scale updates in real time so relative size differences are immediately readable
- Mid-sized players occupy the most contested zone — large enough to hunt small players but still vulnerable to the top ranks
- Rank position is displayed live, making every absorption move meaningful to standing
Split and Eject Tactics
Players can split their mass forward to catch fleeing opponents or eject matter to bait, feed allies, or reposition quickly.
- Splitting halves your current mass across two moving pieces, both of which can absorb
- Ejecting matter reduces your size but can lure opponents into range or support a teammate
- Recombining split pieces takes a cooldown window, leaving a vulnerability gap after aggressive plays
Territory Race
Claiming Ground Against Everyone
The map is the score — paint more than anyone else.
Vacuum.io puts players on a shared map where the goal is to cover as much surface as possible with your color, competing directly against rivals doing the same in real time. The map is the arena — territory gained by one player is territory denied to all others, making every move a spatial decision. The leaderboard reflects not kills but coverage percentage.
Competitive Mechanics
Common Questions
What does the player control in Vacuum.io?
You pilot a vacuum-like vessel that moves around the arena and absorbs smaller debris, particles, or weaker opponents to increase your size.
How does the absorption mechanic work?
Your vessel pulls in objects and players that are smaller than your current mass — the larger you grow, the wider your effective pull range becomes.
Can larger players be defeated?
Yes — maneuvering to avoid a bigger opponent while absorbing enough mass to close the size gap is the primary strategic tension of each match.
What fills the arena besides other players?
Scattered resource particles and neutral objects populate the field, giving smaller players a way to grow without immediately competing against larger rivals.
How is performance measured during a session?
A live leaderboard tracks the largest players in the current arena by mass, updating in real time as players absorb or are absorbed.
Does the game require any account or login?
You can enter a display name and jump straight into the arena without registering — the session begins immediately in the browser.
