@chain.reader Watch this space. Swaroop is applying his very capable brain to the problem at this very moment. Hopefully Penpa is bouncing back in a big way.

Changed the display puzzle and link, reverted to an older version of the same puzzle that has a valve in it. Added the rules for the valve. Solution code is the same. And may I apologise for the head scratching caused by the previous 3/4 deadly pattern, a fine example of a last moment change gone wrong. Lesson learnt, I hope.
