Slide the tiles.
Route the water.
A sliding-tile pipe puzzle. Each level starts as a scrambled grid with one empty cell. Slide tiles into place until every colored entry is connected to its exit, then press Run to test the network.
Three Steps to Solve
A focused puzzle loop: slide, connect, run the water.
Slide
Tap or swipe a tile next to the empty cell to slide it into place. Repeat to reshape the board into a pipe network you can run.
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 a scrambled N×N board with one empty cell. Slide tiles into the empty cell until each colored entry has a sealed pipeline to its exit, then run the water to verify.
