The Weakest Link
The original format features a team of six contestants who take turns answering general knowledge questions. The object of each round is to create a chain of six consecutive correct answers and earn an increasing amount for a single communal pot within a certain time limit. An incorrect answer breaks the chain and loses any money earned in that chain. However, before their question is asked, a contestant can choose to bank the current amount of money earned in a chain to a safe pot, after which the chain starts afresh. A contestant's decision not to bank, in anticipation that they will be able to correctly answer the upcoming question allows the money to grow, as each successive correct answer earns proportionally more money.
