OFFICIAL COMMENT: The picture clues have ended for now. So here come some cryptic word ones. They can be read in conjunction with the picture ones. You do not have to have understood the picture ones to get these ones.
I’m really interested to read the “how the winners won guide” because after all these clues, almost all of which I think I understand, I’m still absolutely stumped! The Code Book by Simon Singh is providing nice breaks though!
