9 Patch Puzzle Quest

A Puzzle game that plays in the browser: 9 Patch Puzzle Quest starts on the click and keeps its progress there. Taps and swipes are the whole vocabulary — a phone plays it best. Listed under educational, logical, math.

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.
