Plumber

Plumber is a pipe-rotation puzzle with a one-minute deadline on each layout. You need a route from the valve to the outlet, with the arrows pointing along the flow. Later layouts mix the working route with spare pipes, so turning every piece will waste time you may need to finish.

How to play Plumber

• Tap or click a pipe to turn it a quarter-turn clockwise. Pieces stay in their positions, and cross-shaped junctions cannot be rotated.
• Connect the valve on the left to the outlet on the right. The green arrows on straight pipes must point in the direction the water should travel.
• You do not have to use every pipe. When the required route is correct, the valve opens automatically and the level ends.
• Finish before the one-minute timer reaches zero. Faster solutions earn more stars, up to three; if time runs out, retry the current level.
• There are 30 levels. Progress is saved, but completed levels are crossed out and cannot be selected again from the level menu.

Tips

• If a straight pipe fits but its arrows face backward, tap it twice more. Its shape will line up again with the direction reversed.

Can you get the water flowing with three stars?
