About Agar.io
Play Agar.io, the classic cells-growing multiplayer game. Control your tiny cell, eat smaller cells, grow larger, and split to capture other players online instantly in your browser. Agar.io is built for shared screens and online lobbies alike. Hit Play to jump in. Fans of multiplayer will feel at home, and the io and casual elements give it extra range. Pick it up for a short break or settle in for a while — it runs well on phone, tablet, and desktop alike.
A couple of things help once you get going: In team modes, pick a role early (attacker, defender, support) so the squad balances. Take a break after three rounds; multiplayer tilt is real and hurts your rating.
Jump into Agar.io free on Glaze Games and see how far you can get. No paywall, no install — just open it and play.
