The ultimate quiz show, Grand Slam pits former winners of the main TV quizzes (Mastermind, Fifteen-to-One, Countdown, etc.) against one another, face to face. Grand Slam is the toughest quiz on television, testing all aspects of mental agility and requiring contestants to put their money where their mouths are – each contestant pays one grand in order to take part – and the winner takes all. Presented by Carol Vorderman and James Richardson.
