Rotate the pipe tiles until water from the central pump reaches every single pipe. The finished network is one connected tree — no tile left dry.
How to play: tap a tile to turn it 90° clockwise. Right-click or long-press to lock tiles you are sure about. Water flows from the pump automatically after every turn — connect all pipes to win.
