IO games are a kind of multiplayer online games that you can enjoy on web browsers or mobile devices. They usually feature simple graphics, easy controls, and are made to be straightforward to pick up but tough to master. Most of them are free-to-play and don’t need any downloads, which makes them available to a broad audience. You can play IO games solo or in teams, and they’re built to be competitive, fast-paced, and super addictive.
The name ‘IO games’ comes from the .io domain extension they use, which was initially given to sites linked to the British Indian Ocean Territory. The first IO game, Agar.io, hit the scene in 2015 and quickly gained traction thanks to its straightforward gameplay and unique idea. Since then, lots of other games have popped up, like Slither.io, Hole.io, and Diep.io, among others.
