Weighted Seesaw

Weighted Seesaw is listed here under Puzzle. There is no launcher and no install between you and it. It is built for touch, so a phone or a tablet is the natural place for it. Its tags here are 2d, balance, block, draw, puzzle.

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.
