Simon Gregson, John Thomson, Ricky Tomlinson

Coronation Street's Simon Gregson (Steve McDonald), his former co-star John Thomson and The Royle Family's Ricky Tomlinson take part in 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 gather, the better their chances of collecting the £20,000 prize for their selected charity.
