 Teams compete for a jackpot of £2,500 for their charity, plus £250 for every pointless answer given before the final round.The jackpot does not roll over if not won, but the programme rewards all teams with £500 for taking part, regardless of how well they performed.The show's format (originally to be called "Obviously") was conceived by Tom Blakeson, Simon Craig, David Flynn, Nick Mather, Richard Osman and Shaun Parry, producers at Endemol UK, in 2009.
