Puzzle Of Pipes is a cross between the classic game Pipe Dreams and those sliding picture puzzle games. You have to rearrange the peices before the water begins flowing!
To play the game, re-arrange the tiles to allow the water to flow through them. The bottom of the screen shows you how many tiles you have left before you can stop working and progress to the next level. You can also hold down the action button, and tap a tile, to randomly replace it with another tile, but doing so will cost you 5 points. Each piece you get water into is 10 points. The cross pieces score a bonus 10 points the second time through.
