Ninja Run 3D

Open Ninja Run 3D and you are playing — an Arcade game that runs on the page rather than beside it. Taps and swipes are the whole vocabulary — a phone plays it best. Listed under .io games, 3d, action, adventure, boy.

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.
