Sword Master

Open Sword Master 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. Catalogued as action, adventure, casual, hypercasual, ninja.

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.
