What Are .io Games?
.io games are browser-based multiplayer games that drop you into a shared arena with dozens or hundreds of other players. The core loop: start small, grow bigger, dominate the leaderboard. Minimal graphics, simple controls (often just mouse movement), instantly accessible to anyone.
The genre exploded in 2015 with Agar.io and has expanded into battle royale, territory control, team combat, building, racing, and more.
