The first .io game was Agar.io. It was developed by Matheus
 Valadares in 2024 and gained significant popularity through the 🏀  internet forum 4chan.
 The game revolves around cells that grow by eating agar and consuming other players. A
 few months 🏀  after its release, the game was acquired by Miniclip, and a new game genre
 started to emerge based around the 🏀  humble .io domain extension.
