Based upon the original Netherlands format of the game show, each episode sees a contestant choosing one of 26 briefcases, each containing a cash amount between $1 and $250,000, and then attempting to win as much as possible either by gambling on having a high amount in their chosen briefcase, or making the game's hidden operator, named "the Banker", offer a considerable cash sum for their case regardless of what is inside.
The second season of the show premiered on 21 November 2007, and increased to two episodes aired per week, on Wednesdays and Thursdays at 8:30pm.
[1] After picking one of the 26 briefcases as theirs to keep, the contestant then selects 6 of the remaining 25 cases to open, revealed one at a time.
This is followed by a phone call by The Banker, a silhouette figure lit only dimly from inside a box overlooking the stage, who makes an offer via telephone to Adrian to buy the contestant's case (The Banker's voice is never heard, except for Adrian himself).
If the contestant accepts the banker's offer (by pushing a stylized red button enclosed in a glass case), the game ends and they win the amount of the offer, and the value of the case that they chose at the beginning of the game is then revealed along with the whereabouts of the remaining prizes.
A lucky draw is held at the end of the game from the pool of viewers who chose the correct briefcase.
