This article describes the new NBC game show called "Deal or No Deal" The rules are described on the NBC website as:
The rules are simple. Choose a briefcase. Then as each round progresses, you must either stay with your original briefcase choice or make a "deal" with the bank to accept its cash offer in exchange for whatever dollar amount is in your chosen case. Once you decide to accept or decline the bank's offer, the decision is final.
To fully understand the game you should play it here. Choose "game" from the options and go to the bottom of the page that comes up and choose "Start game".
The Times article observes that it is not known how the bank determines its offers. Kourlas says that, at a meeting at his house to discuss the game, some thought the decisions my be based on probability concepts such as expected values and others thought that it had "psychological--but not logical--coherence.
Of course the game as played on the Internet the bank clearly has a strategy for determing the offers and if this were known we would have an optional stopping problem reminiscent of the famous secretary problem. This is obviously presents a nice challenge for students in a probability or statistics class.
You can read more about this game enclding a discussion of the role of statistics in such a game here from Wikipedia.
