Channel 4: Deal or No Deal
Contestants try to beat the banker and guess the contents of mystery boxes to win a big-money prize. In a game-changing twist, players could now win up to £500,000 by doubling their winnings with box 23 - if they are brave enough to buy it with what they have already won. Presented by Noel Edmonds.
The contest ends at glamping site Camp Katur in Kirklington, North Yorkshire, where Kerry Roy and Nicola Wilding hope to wow their guests with their unique `geodomes' and see-through pods.
