Agario is a popular and addicting game that has simple rules to play. If you don’t know the rules, you can learn them easily and start to play now. You start the game with a small blob and grow it while you eat pellets. Once you are big enough, you can also eat smaller ones. Note that you will also be target of bigger blobs as they can eat you. The more you grow, the more you move slowly. So you need to split your blob into two pieces to move fast and give a piece to the bigger blobs. Agar io is one of the great unblocked io games.
