Paint With Diamonds

A Puzzle game that plays in the browser: Paint With Diamonds starts on the click and keeps its progress there. It is built for touch, so a phone or a tablet is the natural place for it. Listed under 3d, arcade, color, coloring, number.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Close the tab and come back later; the game is still one click away.
