As one of the most popular online multiplayer games, challenges you to compete against other players as you try to grow and survive. Step in the relentless cellular world where you only have two choices, eat or be eaten! Start out as a small cell and navigate through the map trying to evolve by eating others around you. As you successfully consume others, you grow in size and climb the food chain step by step. Be prepared though! Growth will allow you to eat bigger cells than before but it'll also catch the attention of others. No one would like to miss the chance to have a big and nutritious meal!

Experience the addictive gameplay of in 5 different game modes! In FFA (free-for-all), you start as a small cell, and your objective is to gain as much mass as possible by eating agar and other smaller cells! As you gain more mass, your movements will become slower. Once you reach a sufficient mass, you can split and multiply yourself! In Battle Royale, the competition is real! Race against 3 other players as each of you tries to become the biggest cell on the gradually shrinking map. Team up with other players in Teams mode and try to take over the map as you collaborate with your teammates. Experimental mode is where the developer tests new features so you might have a taste of those here. Lastly, Party mode is where you can play with your friends on a private server!

In Agario, you can save your progress and play with your friends by signing in with your Facebook account. Once you have an account, you'll gain access to the game shop, leaderboards, daily quests, and gifts. In the shop, you can spend the coins you earned to unlock new skins and upgrade the appearance of your cell. Do you like the genre of Agario? Discover our collection of other .io games!
