Monster Up

Open Monster Up and you are playing — a Clicker game that runs on the page rather than beside it. Taps and swipes are the whole vocabulary — a phone plays it best. Catalogued as 1 player, 2d, action, air, fun.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. It costs nothing and asks for nothing: no registration, no download, no launcher.
