Deal or No Deal begins with a large number of suitcases set up on the stage, each of which holds a different sum of money, as well as a mystery case. Some of these suitcases hold a very small amount, while others hold quite a lot. The player chooses different suitcases to open, at which time the amount of money in the given suitcases is eliminated from play. The player continues to eliminate cases until he or she walks away with an offered sum or gets down to the final suitcase, when he or she may open the last case or switch it with the mystery case.
This is where the unique mechanic of Deal or No Deal comes in: The Banker. The Banker is a mysterious figure that calls the host of the show and offers the player the chance to walk away with a sum of money based on the remaining suitcases. So, for example, if the player has eliminated suitcases and is left with one containing ten thousand dollars, one with five hundred, and one with one hundred, he or she will be given the option of walking away with a sum between these three values or attempting to eliminate the smaller sums.
This mechanic essentially makes Deal or No Deal a combination of chance and playing the odds. Each episode also has some unique mechanics built in, which change the way the game is played somehow. In one episode, the host took the form of an ice cream vendor, and drew weather cards with a sunny card benefiting the player and a rainy card hurting them. These mechanics add a bit more chance to the game and make sure that each game is played slightly differently than the previous one.
Deal or No Deal has garnered attention from mathematicians, professional gamblers, and statisticians as to what the best choice in a given scenario is. Players can attempt to prepare for the actual game by learning what the chances of getting a better result by choosing “no deal” are, as well as when it is wise to walk away. Interestingly, studies conducted on how the show’s contestants respond to choices indicate that instead of evaluating their choices based on absolute monetary value (that is, whether they will win twenty thousand dollars or ten thousand), they tend to make choices based on relative value (that is, whether one choice appears to give more than the initial value).
Deal or No Deal presents a very interesting experiment for anyone interested in gambling, math, and statistics. There is a digital version of the game available online, albeit with no actual cash prizes, for those that want to get a taste of what it’s like to play.
