IO games are free online games you can play in real-time on your computer. Online gameplay is the thing that most io games are about. Aside from that, most of these games are built on the io domain extension, which stands for 'Indian Ocean.' Since "Input/Output," a familiar term in computing, is shortened to "IO," this top-level domain extension is popular with software engineers.
How IO Games Grew
Agar io was the first io game. It was made by Matheus Valadares in 2015, and the internet forum 4chan helped it become very famous. The game is all about cells that grow when they eat agar and eat other players. A few months after the game came out, Miniclip bought it, and a new type of game based on the simple io name extension began to take shape.
