From the mind of Projoy via The Banter Page: "One person sets a conventional hangman problem, but only other players are allowed to reveal the letters or add lines to the scaffold. Other players take guesses in turn as to which letters are in the word. The players who arbitrate over what letters are in the word are not allowed to confer. The shape of the word can only emerge through tacit mutual consent - via, in other words, the collective consciousness." (Winning move is "hanged")
It's risky, but I feel certain this is an awkward one. I'm not going to suggest 'Q': although I do feel there's one in there I'd like to get your views first. A 'Q' would suggest a 'U' unless it has some Arabic origin.
