Slide the lines.
Route the water.
A sliding-line pipe puzzle. Every cell on the board holds a tile — you shift whole rows and columns with wrap-around until every colored entry is connected to its exit, then press Run to test the network.
Three Steps to Solve
A focused puzzle loop: shift, connect, run the water.
Shift Lines
Drag a row left or right, or a column up or down, to slide the whole line by one or more cells. Tiles wrap around — what leaves one edge appears on the opposite edge.
Connect Colors
Each color (blue, red, green) must reach its matching exit through a sealed route. Mix two colors in one pipe and the level fails.
Run Water
Press Run to start the network analyzer. Leaks, dry exits, and color mixes are reported with a status message — fix and try again.

How It Works
Each level gives you an N×N board with every cell filled by a tile and a starting scramble. Slide entire rows and columns until each colored entry has a sealed pipeline to its exit, then run the water to verify.
-
Drag a Row or Column
Touch a row to slide it left or right; touch a column to slide it up or down. Multi-step drags shift several cells at once.
-
Run the Test
Start the network analyzer. Leaks, dry exits, and mixed colors are reported immediately.

Sliding-Line Mechanic
Shift whole rows and columns with wrap-around — like rotating a face of a Rubik's cube. Every gesture moves a line of tiles at once.
