Pipes
Rotate tiles to connect every pipe into one flowing network.
The rules
How to play
- 01
Rotate to connect
Click any tile to rotate it a quarter-turn clockwise. You can only rotate tiles, never move them.
- 02
One single network
Every pipe must join into one continuous network, and every pipe opening has to connect to another pipe.
- 03
No closed loops
The finished network must be a tree — no rotation may close a loop back on itself or leave a section stranded.
- 04
Flow from the source
Water flows out from the source tile. When the whole network is linked, every pipe fills and the puzzle is solved.
- 05
Lock what you know
Right-click a tile to lock it once you are sure it is placed correctly, so a stray click cannot rotate it.

Four ways to untangle the grid
Start from edges
Edge pipes have fewer connection options, making them easier to solve first.
Focus on end pipes
End pipes must connect to exactly one neighbor, limiting their rotation options.
Avoid loops
If a rotation would create a closed loop, it's incorrect.
Use the lock feature
Lock tiles you're confident about to focus on the remaining ones.
