Smashy Bird

Browser Hypercasual: Smashy Bird needs a tab and nothing else. Taps and swipes are the whole vocabulary — a phone plays it best. Its tags here are arcade, bird, flight, html5, mapi games.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Everything runs client-side, so there is nothing to set up before you start.
