Waterputer

Water streams down from the top into a grid of empty boxes, connected by rotatable pieces of plumbing. The player's task is to rotate and rearrange the pieces so that all the boxes are filled up with water. This must be done quickly - the water will inevitably leak and pool at the bottom of the screen, then start rising upwards, drowning row after row of boxes as it does. The level must be finished before the water reaches the top.
