If Father Christmas was a fan of the film Saw, he'd probably come up with the RollOnFriday Christmas Quiz.
12 fiendish posers await you. The answers are buried in this year's stories, helpfully narrowed down to those featured in the Review of the Year 2019.
Last year's Christmas Quiz winner, from Norton Rose Fulbright, picked £100 as her prize. But there is another option: a meal with RollOnFriday.
Have a go, just pick wisely if you win.
Please note, you'll need to give an email address so you can be contacted if your name is picked out of the hat. Good luck.
