The Vault is a British game show based on the original Israeli version called HaKassefet ) that aired on ITV from 11 May 2002 to 24 August 2004. It was first hosted by Davina McCall in 2002, then hosted by Melanie Sykes from 2003 to 2004 and finally hosted by Gabby Logan who stepped in for Sykes for the latter half of 2004 when Sykes went on maternity leave due to her pregnancy. Format Seven contestants competed per episode in the first series, eight in the second, and nine in the third. Each contestant guessed a four-digit combination for the Vault, which held a cash jackpot that began at £100,000 after being won and increased by that amount for every game it went unclaimed. The four whose guesses were farthest away became "brokers," who could offer to sell correct answers, while all others played for a chance at the jackpot. Brokers were referred to only by their occupation. Starting with the second series, eight home viewers who had called in to the studio were chosen at random to play as brokers in addition to the four in the studio. A new set of call-in brokers was chosen for each round, referred to only by their telephone line numbers (1 through 8). Round 1 Each player individually had three minutes to answer up to 10 questions, with all other players sequestered in soundproof booths backstage. Players were spotted £1,000 to start the round, could offer multiple guesses without penalty, and could pass as often as desired. Once a player had answered or passed on all 10 questions, they could negotiate with one broker at a time to get answers to any questions that had stumped them. Each studio broker could press a button to illuminate a light on their podium and signal their readiness to make an offer. However, the player would not know if a particular call-in broker might know an answer until/unless they called on that person. If the player and a broker agreed on a price, the broker then stated their answer; if it was correct, the price was paid to them out of the player's winnings for the round. Each correct answer awarded £100 to the player, regardless of whether they or a broker had given it. Answering all 10 questions correctly awarded a £5,000 bonus.
