13th to 14th December
This round marks the start of the William Hill World Darts Championship, the annual extravaganza at Ally Pally. The tournament is the first one in PDC's history without Phil "The Power" Taylor, and his conqueror last year, Rob Cross, will be looking to defend his fairytale debut title from last year. He will face tough opponents in world No 1 Michael van Gerwen and Gary Anderson, who are both looking for their third PDC title. Whoever wins, make sure you do too by completing the quiz below and you could be the lucky owner of a Heineken Christmas Jumper to help you get into the festive spirit. By entering you will also be entered into the draw for the grand prize of a trip to Australia for two!
In order to enter we would like you to test both your mathematical and darts knowledge by giving us the lowest number that cannot be scored with one dart, give it a go!
