Agar.io is an addictive multiplayer game in which players control a small cell in a vast petri dish. They aim to grow by consuming smaller cells while avoiding larger ones.

The game’s simple yet strategic mechanics involve collecting food pellets to increase size while navigating a competitive environment filled with real-time opponents.

As players grow, movement slows, requiring tactical decisions on whether to split their cell for speed or risk being overtaken.

The game also features viruses that can aid escape or fragment more prominent players. Agar.io’s intuitive controls, global multiplayer experience, and custom skins make it a highly engaging and competitive experience.
