About .io games
The .io genre started as a joke domain and became its own category of gaming. The formula is simple and addictive: a single shared arena, a grow-or-die loop, a leaderboard, and a respawn button you will hit a hundred times in a sitting. Because everything runs in WebGL inside a browser tab, there is no install, no patch day, and no launcher — you go from a cold tab to a live lobby of real players in a handful of seconds.
