How to play Battle.io
The rules land within the first few seconds of play. You will want a keyboard for this one — the arrow keys / WASD carry most of it, and the table below has the rest. It fills the player in landscape, so use the fullscreen button on desktop and turn your phone sideways on mobile. There is no penalty for failing, so push a little harder than feels safe.

|---|---|
| Arrow keys / WASD | Move and jump |
| J / K / L | Punch, kick and block |
On mobile: Tap and swipe on screen. Turn your phone sideways — this game is designed for landscape and fills a horizontal screen.
Why it is worth playing
What keeps Battle.io worth returning to is how quickly a single round resolves. It respects your time — you are never more than a click from another attempt. It is not trying to be anything larger, and it is better for it.
