Agar.io

In the petri-dish world of Agar.io, a tiny cell drifts through a crowded server and grows by swallowing colored pellets. Size changes everything. A larger cell can absorb smaller rivals, while bigger players circle nearby and wait for an opening. No download or purchase gets in the way. Pick a regional server in your browser and enter the arena.

How to play?

Move across the field and absorb pellets to gain mass. Slip away from larger cells until your size gives you safer targets. Press Space to eject part of your mass in a burst. That move can create distance from a threat or help catch a smaller cell. Press W to feed mass to another player. Use it to bait reactions, set up a chase, or test whether someone plans to cooperate. Trust doesn't last long here. A large cell that drifts past may still be waiting for you to grow.
