My Brewers is an old (1999) version and I can't find reference to the unclued lights in that. Have been meaning to invest in a more up-to-date version - can anyone confirm that a more modern version holds the key, or am I missing something that is in my older version?
It can also be done by Googling the answers, which are pretty straightforward and unambiguous… though it would have been quicker to go out a buy a copy of Brewer's!
