How to play Cannon Ball IO
Press play and the first round teaches you the rest. Everything is done with the mouse. No key bindings to learn, so the phone version plays identically to the desktop one. It fills the player in landscape, so use the fullscreen button on desktop and turn your phone sideways on mobile. If a round goes badly, restart — attempts are cheap and it is usually the fastest way to improve.
