Controls

You play by rotating pipe segments. On a phone, tap any pipe on the grid and it turns ninety degrees. On a laptop, click the same pipe with your mouse; there's no dragging involved either way. Keep rotating segments until they line up into a continuous path.

The goal is one unbroken connection:

• Rotating pipes is your only action. Each click or tap turns a segment a quarter turn, so a piece may need several turns to point the right way.
• The path must run unbroken from the water source to the outlet. Every segment along it has to connect to the next, or the water leaks and the level isn't complete.

Junctions and dead-end pipes are added at later levels to mislead you, so not every pipe belongs on the final path.

You solve a level by completing the leak-free connection. The game counts your moves, so solving in fewer clicks or taps is its own reward, and the grid grows from 5x5 to 8x8 across eight levels.

Tips

• Start from the source and the drain. Working outward from the two fixed endpoints gives you certain starting points, since the pipes right next to them can only connect one useful way.
• Solve the forced pieces first. Corner and edge pipes have fewer possible orientations, so locking those in early narrows down the middle of the grid and reveals the path's shape.
• Ignore the decoy pipes. Later levels include dead ends and extra junctions that lead nowhere, so once you spot a segment that can't join the path, leave it and focus on the real route.
• Trace the whole route before rotating everything. Picturing the path from source to drain first means you rotate pipes with a plan, rather than turning them at random and hoping they line up.
• Aim for fewer taps. The game tracks your move count, so thinking about the shortest way to orient each pipe, rather than spinning it in full circles, keeps your solve efficient.
• Fix leaks by checking each joint. If water isn't flowing, walk along your path and check that every segment truly connects to the next, since a single misaligned joint breaks the whole line.
