Agar.io is a massively multiplayer online action game developed and published by Matheus Valadares. It is the prequel to a string of similarly named .io games, such as Slither.io and Diep.io.
In 2015, it gained popularity via word of mouth on social networks and became one of the most popular web and mobile games that year.
Game information[]
Players individually control a different coloured cell and must use their mouse to lead it around to eat other cells to grow bigger. They also need to watch out for larger players, especially those who are in the top ten on the leader board, who can easily consume smaller players. They need to survive for the longest time possible; if they don't then they will return to the start screen and can play again if they wish.
Players can go by different usernames and use different skins using mods; such skins include YouTuber logos, countries' flags and memes.

In episode six, he achieved first on the leader board for the first time and discovered a skin of his channel logo to use in game. In episode eight he put out on Twitter asking for fans to join him.
