Agario is a fantastic and enjoyable unblocked game that most players like. As it is simple to play, the rules are simple: Small blobs can’t eat bigger ones. So, they need to stay away from them. By the way, they can attack smaller blobs. There are also green blobs in the game and these are viruses. Bigger blobs shouldn’t touch them. Otherwise, they will be split into several pieces. But if blobs are small, they can hide in viruses so that they can protect themselves against big blobs. If you are interested in unblocked io games, you can try agar io.
