Hungry Crab

Open Hungry Crab and you are playing — a Puzzle game that runs on the page rather than beside it. Taps and swipes are the whole vocabulary — a phone plays it best. Listed under 2d, casual, fun, puzzle.

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.
