Agar.io is the game that launched the entire “.io” genre of free-to-play, browser-based multiplayer games. It’s a survival game at its core, set in a minimalist, colorful world that looks like a microscope slide. You control a single circular cell. Scattered across the map are tiny, stationary colored pellets of agar, which you can eat to grow bigger. More importantly, the map is filled with other players who are all trying to do the same thing! The golden rule is simple: if you’re bigger, you can eat them. If they’re bigger, they can eat you! This creates a constant, exciting tension where you are both the hunter and the hunted.
The reason Agar.io became so popular is its beautiful simplicity. Anyone can understand the rules in just a few seconds, making it incredibly easy to pick up and play. However, beneath this simple surface lies a deep layer of strategy. You have to think about positioning, when to be aggressive, and when to flee. The game introduced unique mechanics like splitting your cell to lunge forward or ejecting mass to help teammates, which turned a simple concept into a complex and competitive experience. For more about its history and impact, dedicated fans have created awesome content like this fan review on Fandom that explores its legacy.
Your main objective in Agar.io is to grow your cell as large as possible by consuming agar pellets and smaller player cells. The game ends for you when a larger cell consumes you, but don’t worry! You can instantly jump back into a new round and try again. The core loop of the game is a constant cycle of growing, hunting, and avoiding danger. You start small and vulnerable, focusing on eating the tiny pellets around the map. As you grow, you become a bigger threat and can start hunting smaller players. But with greater size comes slower movement, making you a target for even larger players who can split their cells to catch you. You must constantly be aware of your surroundings to climb the leaderboard and dominate the server.
Mastering the controls is key to winning. The controls are simple to learn but take practice to use effectively. Here is how to navigate the world of Agar.io:

.io was originally the country code top-level domain for the British Indian Ocean Territory. Game developers started using it for their new wave of simple, browser-based multiplayer games because “io” also suggests input/output, fitting for a game. Agar.io was the game that made this trend famous!
Yes! While the main “Free For All” mode pits everyone against each other, Agar.io also features a “Teams” mode. In this mode, you’ll be assigned to a colored team (Red, Green, or Blue) and must work together with your teammates to dominate the other colors.
The small, non-moving colored dots are “agar,” the food your cell eats to grow. The larger, moving colored circles with names are other players from all over the world. The spiky green circles are viruses, which are a special map element you can use strategically.
In the browser version, you can unlock certain skins by using specific usernames. For example, typing “Doge” or “Earth” as your name will give you a special skin. In the mobile versions, there is a larger system of earning coins to unlock and purchase a wide variety of cool skins and potions.
