The prompt

Make a pipe-rotation puzzle in one HTML file. Build each network as a random spanning tree from a central pump so every level has a solution, then spin each piece to a random angle. Tapping turns a piece; water flows live from the pump through every joint that lines up. Solved when every pipe has water and no pipe end points at nothing.

Claude wrote this game from a short brief like this one. It was then played, tested on phones and tuned before it went up here.

How to play

Water starts at the pump in the middle.
Turn pipes so their ends meet. Water flows instantly through every joint that lines up.
You win when every pipe is full and no end is left open.
Round caps mark the ends of the network.
