Yellow Pipes

Yellow Pipes is a Puzzle game you can be inside of about a second after clicking. It is built for touch, so a phone or a tablet is the natural place for it. Tagged 1 player, 2d, board, draw, hypercasual.

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.
