My friend Liz writes a regular Christmas quiz.  The clues have a different theme every year, and you can usually work out what the theme is after solving a couple.

If you'd like to have a try, you can download it from here -

The solutions are usually posted in the New Year.  But you'll usually know when you've got them right.

Several members of my family like to have a go at it on Christmas Day - and we usually solve it all between us.  (but it's still a gentle competition between us to see if anyone can get it all on their own)
