What is an IO Game?
IO games are a genre of multiplayer browser games that became massively popular after the release of Agar.io in 2015. Named after the .io top-level domain where most are hosted, these games share common traits: instant play, simple mechanics, and real-time multiplayer action.
Why they took over
- Zero friction: no download, no account, click and play
