.io games are simple online games you join in seconds, with lots of players in one arena at the same time. You start small, grow by eating, building or winning fights, and try to climb the leaderboard before someone bigger takes you out. The name comes from the .io web addresses many of them use. They need no account, and a round can last a minute or an hour depending on how well you do.
