Merge the Presidents

Merge the Presidents is listed here under Puzzle. There is no launcher and no install between you and it. Taps and swipes are the whole vocabulary — a phone plays it best. Its tags here are arcade, celebrity, collecting, kids, logic.

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.
