Compete against others in this classic multiplayer survival game where you must grow your cell by consuming smaller targets while avoiding larger opponents in a massive arena.

About Agar.io

Agar.io is a skill-based multiplayer game that places you in a competitive environment where size determines survival. Starting as a small cell, you navigate the play area to absorb pellets and smaller players, gradually increasing your mass. The core challenge involves balancing your growth with the risks of being consumed by larger entities roaming the map.

The game emphasizes strategic movement and timing. As you grow larger, you naturally become slower, requiring tactical decisions on when to divide your mass or eject feed to stay mobile. This battle royale style experience rewards players who can outmaneuver rivals and react quickly to changing board conditions. It is ideal for those seeking competitive, session-based gameplay.

How to play

Use your mouse to guide your cell across the arena, collecting small pellets to gain mass. As you grow, identify smaller players to consume while keeping a safe distance from larger ones. Use the spacebar to split your cell into two to catch faster targets or escape danger. Press W to eject mass, which can be used to influence your surroundings or interact with other cells in the arena.

Tips for beginners

  • Split only when you are certain you can consume a smaller target or need an emergency escape.
  • Use the edges of the map to corner and trap smaller opponents.
  • Avoid getting too close to larger cells that can easily divide to catch you.
  • Remember that splitting makes you faster but also makes you vulnerable to more players.
