Ben Shephard invites Strictly judge Bruno Tonioli, TV doctor Zoe Williams and former Corrie actress Catherine Tyldesley to take part in a special edition of the quiz show, in which contestants answer questions to win turns on an arcade-style machine. Dropping tokens down a choice of four chutes, they hope to knock piles of them off a moving shelf - and the more they collect, the better their chances of collecting the ú20,000 prize for their selected charity.

Ben Shephard finds out if Rory Cowan, Kate Garraway and Gok Wan have what it takes to beat the extraordinary machine and win thousands of pounds for charity.
