Agario, one of the exciting unblocked io games is a fun game and most players enjoy playing. If you haven’t tried this enjoyable game, let’s look at the rules: The game is played with a blob. It is moved around the playground, pleps are found and eaten so that the blob grows. The most important rule: Only big blobs can eat smaller ones. When your blob is big enough, you may catch smaller ones. But you will need to run away from bigger blobs. Sometimes you may need to split it into two pieces to give them something to eat. Have fun!
