Open the valve. Level the tanks.
Tanks stand in a row, joined by pipes. Throw a lever and the valve opens, the liquid runs until it settles, and the valve shuts for good. Every lever works exactly once. Bring the surface to the red line and the basin is cleared.
It looks simple. It isn't forgiving.
A pipe set high only lets the top of the liquid through. A lever thrown too early moves nothing and is gone. Most first moves are traps — the puzzle is in reading the order before you touch anything.
- 256 basins, from a single valve to two-tier rigs with drop pipes
- A handful of taps per basin, one screen, no timer
- No hints. Retry any time, as often as you like
- Heavy, slow liquid that leans, pours and settles
- Industrial sound and five original tracks, all synthesized
- Progress saved to the cloud with Google Play Games
