Let's Make a Deal is a classic American television game show that was initially broadcasted on CBS from 1963 to 2003, making it one of the most longstanding shows in the history of American television. The legendary series was created by Stefan Hatos and Monty Hall, who also served as the original host until 1991, succeeded by Bob Hilton briefly and then by Billy Bush. The show's distinctive blend of decision-making, luck, and the unpredictability of prices wrapped in a package of excitement and comedy greatly contributed to its popularity and longevity.

The format of Let's Make a Deal involves contestants selected from the audience, who are usually dressed in a wide variety of costumes to catch the producer's attention and increase their chances of being picked. Each selected contestant is given the opportunity to trade an item of their choice that they have brought from home for a chance to win more valuable items or cash that are hidden behind three curtains or within a series of boxes displayed on the stage. The contestant's decision making is the centerpiece of the game, as they must decide whether to keep their original item, or risk it for the unknown prizes behind the curtains or boxes.

Each episode is filled with an assortment of games that test contestants' ability to make deals. Some of the most popular games include "Beat the Dealer", where contestants try to draw a higher-numbered card than the host, and "The Big Deal", which features three doors, behind one of which lies a grand prize, while the other two doors hide lesser-value prizes. Each game involves an element of risk and strategy, as contestants must decide when to stop making deals in order not to end up with a worthless prize, famously known as a "zonk".
