Jewel Blocks Puzzle

Jewel Blocks Puzzle sits on the Puzzle shelf of this catalogue, and opening it is the whole setup process. It is built for touch, so a phone or a tablet is the natural place for it. Listed under arcade, brain, html5, kids, 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.
