About this game
Turn the pipes, carry water to every fountain and leave no end open.
The stone fountains of an old city are thirsty: tap the pipes to turn them a quarter and carry water from the source to every fountain. Every end must meet another pipe and no pipe may stay dry. Six quarters bring padlocked pieces, bridges, one-way valves, two waters that must never mix and gears that turn together. Every line has exactly one solution and is checked by a program; you earn stars and coins, and the line of the day is the same for everyone.

How to play
- Tap a pipe: it turns a quarter. Long press or right click: it turns back.
- Carry the water from the source to the fountains; water flows through connected pipes.
- Close every open end: each end must meet another pipe and no pipe may stay dry.
- Stuck? Undo, or take a hint: it marks the piece that needs turning.
Controls
- Tap or click: turn the piece a quarter
- Long press or right click: turn the piece back
- Keyboard: arrows select, Space turns, Shift+Space turns back, Z undoes, H gives a hint
- Esc or P: pause
Tips
- Start at the source: turn the next pipe wherever the water stops; open ends show as red rings.
- Aim for par taps for the third star: turn every piece only as far as needed; one back-turn beats three forward ones.
- Pieces with a gear mark turn together and padlocked pieces never turn: plan around both.
