In keeping with an annual tradition on this blog (ie I did it last year), I humbly offer readers a Christmas quiz. It is unusual in that no-one is expected to know the answers. Instead, the idea is simply to see who gets closest. All the solutions are numbers.
The beauty of this kind of puzzle is that everyone has a chance to win, whatever age or festive state.
The way I do it with my family is to divide the players into two or four teams depending on the size of the party. There are 20 questions and, to make it fair, each player/team should have equal numbers of questions to answer first and last.
Good luck and Merry Christmas!
