How this game works
How to play Drain
- Goal
-
The water must reach the drain, and nothing may leak. Rotate pipes until every connector matches its neighbor and the glow from the source reaches the drain.
- Rules
-
Leak-free arrangements can form more than one closed shape — the extra loops and capped stubs are decoys, not part of the route. Only the shape that reaches both the source and the drain matters.
- Controls
-
Tap a tile to rotate it. A dripping pipe is leaking: keep turning it until the drip stops. The pulsing cyan tile is the source; the ringed tile is the drain.
