Talpa and Initial for BBC One, 11 July to 29 August 2009 (8 episodes in 1 series)
Two families are set a series of questions and predictions. They're not expected to know the answers already, but to use a combination of estimation and guesswork to come up with a sensible answer. The closest answer to each question gives an advantage in the next stage, and the family that's best at the guesstimation will win a holiday to somewhere exotic.
The show includes challenges in the studio for special guests and famous people. Each episode features someone receiving funding from the National Lottery's sports fund, and promoted a National Lottery product for the 2012 Summer Olympic games.
Original format by Talpa Content B.V., based on an idea by John de Mol.
Augustin Bousfield composed a full score.
