Boxing Day Family Puzzler 2011

As Britain stumbles into Boxing Day, trying to focus and avoid the festive wreckage, what better way to clear fogged heads than with my annual family puzzler?

As regular readers will know, the quiz is unusual in that no-one is expected to know the answers. All the solutions are numbers and the idea is simply to see who gets closest. This gives all participants a chance to win, irrespective of age or festive state of repair.

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 write their guesses down before revealing them. One mark for the closest answer and three if, by some fluke or genius, you get it spot on!

The questions are below; the answers are here and there is a version of both that is easier to print here.

Good luck and have a jolly Boxing Day!
