Pipes

How to play

• Left click a pipe to turn it clockwise. Right click turns it the other way. The pump and the tank cannot be turned.
• Water crawls along every pipe that is connected to the pump. When it reaches the tank, the round is solved. Turning a pipe can cut the water off again.
• Some pipes are decoys: dead stubs that lead nowhere and only get in the way. Every board can be solved, however scrambled it looks.
• A level is one board size. It opens on a board with three decoys. Each time you solve it, the run is laid out afresh with three more decoys, until every square holds a pipe. Solving that full board finishes the level.
• Before your first turn, the size button in the footer cycles the five board sizes, 6x6 up to 10x10, and lays out the one it lands on. After a level is finished it does the same, so the next size is your choice.
• Once you have turned a pipe, the button reads End and gives up the level at the same size.

Scoring

• A solve earns up to 100 points, fewer the further your turns run past the board's par, plus 25 for every decoy on that board. A finished level banks the total of its solves.
• Turns counts your turns on the current board. Best is your best level score for this board size.
