Joe Lycett, Melody Thornton, Henry Blofeld

Ben Shephard hosts as comedian Joe Lycett, Pussycat Doll Melody Thornton and retired cricket commentator Henry Blofeld take part in the game show, in which they must answer questions to win turns on an arcade-style machine. Dropping counters down a choice of four chutes, they hope to knock piles of them off a moving shelf - with the highest scorer playing for the £20,000 jackpot for their chosen charity.
