.io games

You enter the arena as something tiny, grow a little with every move and, if you play it smart, end up at the top of the leaderboard. That's the heart of .io games: simple rules and online matches that start the second you click play. Snake growers, territory painters, cell eaters, tank brawls and battle-royale style survival arenas are the classics of the genre, which takes its name from the web address ending many of these games use.

You usually just type a nickname and go, no account needed. Early on, steer clear of the big players and grow quietly around the edges, as it's the safest way to avoid an early exit. Taking risks pays off, but one greedy moment can cost you everything, and finding that balance is what makes each round exciting.

Since these games are played online, a stable connection helps a lot. All of them run in desktop and mobile browsers without any download.
