Agar.io is an online multiplayer game that follows the simple yet competitive mechanics of the classic "Agar.io." In this game, players control a small cell and aim to consume smaller cells or randomly generated food particles to grow larger. However, players must avoid being eaten by larger cells, which add an element of strategy to the game. Agar.io can be played for free online on web browsers, with no download required. It's a fast-paced game where survival is key, and strategic growth and avoidance are essential for success.

The goal is to become the largest cell on the map by consuming others while staying ahead of larger players. You start as a tiny cell, but the more you eat, the bigger and slower you become. However, as your size increases, so do the risks. Other players may try to eat you, and strategy becomes critical—whether you're avoiding them or using your size to your advantage. The game is easy to pick up, but hard to master, making it a thrilling experience for competitive players.
