Ring It Off

Open Ring It Off and you are playing — a Hypercasual game that runs on the page rather than beside it. Taps and swipes are the whole vocabulary — a phone plays it best. Listed under 3d, coloring, hypercasual, 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.
