Jon Culshaw, Jenni Falconer, Jason Gardiner

Impressionist and comedian Jon Culshaw, TV and radio presenter Jenni Falconer and former Dancing on Ice judge Jason Gardiner take turns on the arcade-style token-pushing machine. Dropping counters down a choice of four chutes, the celebrity contestants hope to knock piles of them off a moving shelf - and the more they collect, the better their chances of scooping the £20,000 prize for a charity of their choice.
