.io Games

The .io format drops you into one shared arena with dozens of other players in real time: everyone starts small, eats to grow, and feeds the leaderboard the moment they get careless. There is no campaign and no ending — just the next run lasting a bit longer. — 8 playable now.

This shelf currently leans toward the snake-and-worm branch of .io: length games where your own body becomes the obstacle. The core skill is the same across all of them — cut off rivals' paths without boxing in your own tail.

Lobbies are live people, so sessions vary: a run can end in ten seconds or carry you to the top of the board. Each page lists devices and orientation so you know before pressing Play whether it is a mouse, keyboard or thumb game.
