The international hit game show "Deal or No Deal" comes to NBC in a five-night event. Hosted by actor/comedian Howie Mandel, "Deal" is an exhilarating game show from the producers of "Fear Factor" and "Extreme Makeover: Home Edition." Each night, the game of odds and chance unfolds when a contestant is confronted with 26 sealed briefcases full of varying amounts of cash -- ranging from a measly penny to $1 million dollars. Without knowing the amount in each briefcase, the contestant picks one -- his to keep, if he chooses, until its unsealing at game's end. The risk element of the game kicks in when the player must then instinctively eliminate the remaining 25 cases - which are opened and the amount of cash inside revealed. The pressure mounts as in each round, after a pre-determined number of cases are opened, the participant is tempted by a mysterious entity known only as "The Bank" to accept an offer of cash in exchange for what might be contained in the contestant's chosen briefcase - prompting Mandel to ask the all-important question - Deal or No Deal? As each case is opened, the likelihood of the player having a valuable cash amount in his or her own case decreases or increases. Viewers will see if truly, fortune favors the bold. The contestant knows that as long as the larger cash prizes haven't been opened, the Bank's deals will only get higher. And if the torn contestant accidentally opens a case with a bigger cash value -- The Bank's offer could suddenly vaporize. Based on the successful format from Endemol that has aired in over 35 countries, "Deal or No Deal" is produced by Endemol USA.
