Sky Rolling Balls

Open Sky Rolling Balls and you are playing — an Arcade game that runs on the page rather than beside it. Taps and swipes are the whole vocabulary — a phone plays it best. Catalogued as 3d, ball, collecting, kids, mobile.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Free to play in the browser, with no install step between you and the first round.
