Now in its 12th year, this is the festive quiz in which no-one is expected to know any of the answers, offering hope to those struggling to focus on this Boxing Day.

The questions relate to events in 2019 and all the solutions are numbers. Contestants must simply use wisdom and judgement to get as close to the right figure as they can.

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 luck, or genius, you get it spot on.

The answers can be found at the bottom of the page. Good luck!
