Agario: As you eat, you will develop further Agario If you are looking for interesting unblocked io games to play, you should try agar io. It is a game that is played with a blob. Move your blob around the playground, find some pellets to eat and grow it. While it gets bigger, it can also eat smaller blobs. So if you have a small blob, you should be careful about bigger blobs. Those with green color are viruses. If a bigger blob touches a virus, it explodes. You can feed viruses to use it against bigger blobs. Besides, you can hide your blob inside them if it is small. Have fun!
