Well, thought i might as well see if the actual puzzle was available online, and so it was.
All very odd and annoying.
So having completed it thanks to the pdf version from an early post in this forum I now filled in my answers in a ridiculously short 4 minutes 7 seconds.
But I am sure like most people on this forum it's the solving that is the fun.
I wonder what might work strangely next week?
Goodnight all.
