Jailbreak was a reality television game show. It was hosted by Craig Charles, and co-presented by Charlie Stayt and Ruth England. It was shown in 2000 by Five in the United Kingdom. Original host Ulrika Jonsson had to pull out of the project due to health concerns over her newborn child. Contestants in Jailbreak had to escape from a mock prison in order to win a cash prize of £100,000. The "prison", at a secret location near Potters Bar, Hertfordshire, was fitted with hi-tech security systems. "Inmates" faced a three-week authentic prison regime, complete with 35 prison guards and a 18-foot high fence topped with razor wire. A number of chinks in the security system were deliberately placed by the production team. Escapes were aided by a series of clues, and by texts from the viewing public with suggestions on escape routes. The show was won by three female contestants Roberta Woodhouse, 29, Hannah Davies, 24, and Laura Hawkins, 22. They broke out of the prison in the early hours of a Saturday morning - 14 days into the show. It has not been commissioned for a further series.

Final Offer is essentially a game show played without a studio audience present. In the hourlong series the "contestants" are sellers of antiques and rare collectibles who get an equally rare opportunity to haggle with four professional dealers -- Jacob Chait, Patrick Painter, Billy Roland and Jordan Tabach-Bank -- eager to outbid one another for the items. One on one, and in the order they choose, the sellers negotiate with the dealers, but there's a catch: Once a seller passes on an offer, there's no turning back. He or she begins the process again with the next buyer in line, hoping the bid they receive is at least as high as the one they just turned down. Let the high-stakes game, in which the highest bidder doesn't always win, begin.

Two players each compete to find the top seven answers of a survey or a list from a board of twelve possible answers. The winning player advances to a final round where they can win up to ¥16,000 in cash/prizes by finding the five answers that were not among the top seven of a survey from the same board, and if they score enough, they can earn a ticket to the Tournament of Champions (Season 4).
