Let's Make a Deal is a television game show which originated in the United States and has since been produced in many countries throughout the world. The show is based around deals offered to members of the audience by the host. The traders usually have to weigh the possibility of an offer for valuable prizes, or undesirable items, referred to as "Zonks". Let's Make a Deal is also known for the various unusual and crazy costumes worn by audience members, who dressed up that way in order to increase their chances of being selected as a trader. The show was hosted for many years by Monty Hall, who co-created and co-produced the show with Stefan Hatos. The current version is hosted by Wayne Brady, with Jonathan Mangum (announcer), Danielle Demski (model), and Cat Gray (live musician) assisting.

The original and most widely known version of the show was broadcast from 1963–68 on NBC-TV, then moved to ABC-TV where it ran until 1976. A weekly nighttime syndicated version of the show was broadcast from 1971–77. Two daily syndicated versions were telecast in the 1980s, one a Canadian-based revival that was broadcast from 1980–81, and The All New Let's Make a Deal, which was telecast from 1984–86. NBC-TV telecast a daytime series in 1990–91 and three episodes of a weekly prime-time version in 2003.
The weekly nighttime syndicated series, seen from 1971–77, was distributed by ABC Films and its successor, Worldvision Enterprises. The 1980 daily syndicated series was co-produced and distributed by Canadian production company Catalena Productions, with its American partner Rhodes Productions distributing the series in the United States (as it would later do with another Catalena production, Pitfall). The 1984 daily syndicated series was distributed by Telepictures. A partial remake called Big Deal, hosted by Mark deCarlo, telecast in the fall of 1996 on FOX-TV. One episode of the show was part of the summer replacement series Gameshow Marathon on CBS in 2006, hosted by Ricki Lake.
On July 8, 2009 a pilot was taped at CBS Television City, with Wayne Brady as host and Jonathan Mangum as the announcer. Alison Fiori was the show's first model, but was replaced by Tiffany Coyne midway through the first season, and Danielle Demski replaced Coyne in 2013 following Coyne's maternity leave. Cat Gray was added in 2011 as live musician. The program premiered on CBS on October 5, 2009, and affiliates may broadcast this show at different times depending on their commitments to syndicated programming. CBS briefly screened two new episodes daily between the cancellation of As the World Turns and the debut of The Talk.
With the conversion of CBS's children's block to an all-HD schedule on September 28, 2013, Let's Make a Deal is the only current network program on the five major American broadcast networks besides CBS's Big Brother not yet broadcast in HDTV, instead broadcasting solely in standard-definition 480i.
Each episode of Let's Make a Deal consists of several "deals" between the host and a member or members of the audience as traders. Audience members are picked at the host's whim as the show moves along, and couples are often selected to play together as traders. The deals are mini-games within the show that take several formats.
In the simplest format, a trader is given a prize of medium value (such as a television set), and the host offers them the opportunity to trade for another prize. However, the offered prize is unknown. It might be concealed on the stage behind one of three curtains, or behind "boxes" onstage (large panels painted to look like boxes), within smaller boxes brought out to the audience, or occasionally in other formats. The initial prize given to the trader may also be concealed, such as in a box, wallet or purse, or the trader might be initially given a box, envelope or curtain. The format varies widely.
Technically, traders are supposed to bring something to trade in, but this rule has seldom been enforced. On several occasions, a trader is actually asked to trade in an item such as their shoes or purse, only to receive the item back at the end of the deal as a "prize". On at least one occasion, the purse was taken backstage and a high-valued prize was placed inside of it.
Prizes generally are either a legitimate prize, cash, or a "Zonk". Legitimate prizes run the gamut of what is typically given away on game shows, including trips, electronics, furniture, appliances, and cars. Zonks are unwanted booby prizes (e.g., live animals, large amounts of food, fake money, fake trips or something outlandish such as a giant article of clothing, a room full of junked furniture, etc.). Sometimes Zonks are legitimate prizes but of a low value (e.g., Matchbox cars, wheelbarrows, T-shirts, grocery prizes, etc.). On rare occasions, a trader appears to get Zonked, but the Zonk is a cover-up for a legitimate prize.
Though usually considered joke prizes, traders legally win the Zonks. However, after the taping of the show, any trader who had been Zonked is offered a consolation prize (currently $100) instead of having to take home the actual Zonk. This is partly because some of the Zonks are intrinsically or physically impossible to receive or deliver to the traders (such as live animals or the guy in an animal costume), or the props/employees are owned by the studio. A disclaimer at the end of the credits of later 1970s episodes read "Some traders accept reasonable duplicates of Zonk prizes." Starting in the 2012–13 season, CBS invited viewers to provide Zonk ideas to producers. At the end of the season, the Zonk declared the most creative was worth $2,500 to the winner, and other viewers' Zonk ideas were also used. For every viewer-developed Zonk, the host announced the viewer who provided the Zonk. The contest has been renewed for its second season in 2013.
As the end credits of the show roll, it is typical for the host to ask random members of the studio audience to participate in fast deals. In the current Wayne Brady version, these are often referred on the CBS version as "quickie deals", and are conducted by the host, announcer, and model each. CBS will post information on the show's Twitter address (@LetsMakeDealCBS) days before taping to encourage audience members to carry and win additional cash for carrying such items. The deals are usually in the form of the following:
- Offering cash to one person in the audience who had a certain item on them.
- Offering a small cash amount for each item of a certain quantity.
- Offering cash for each instance of a particular digit as it occurred in the serial number on a dollar bill, driver's license, etc.
- Offering to pay the last check in the person's checkbook, if they had one, up to a certain limit (usually $500 or $1,000).
Other deal formats
Deals were often more complicated than the basic format described above. Additionally, some deals took the form of games of chance, and others in the form of pricing games.
- Choosing an envelope, purse, wallet, etc., which conceal dollar bills. One of them conceals a pre-announced value (usually $1 or $5), which awards a car or trip. The other envelopes contain a larger amount of money as a consolation prize. The trader must decide whether to keep their choice or trade. In some playings it is possible for more than one trader to win the grand prize.
- Making decisions for another person, such as a spouse or a series of unrelated traders. Sometimes after several offers, the teams are broken up to make an individual decision.
- Being presented with a large grocery item (e.g., a box of candy bars)—almost always containing a hidden cash amount—or a "claim check" at the start of the show. Throughout the show, the trader is given several chances to trade the item and/or give it to another trader in exchange for a different box or curtain. The final trader in possession of the item prior to the Big Deal is usually offered first choice of the three doors in exchange for giving up the item. The contents of the item are only revealed after the Big Deal is awarded (or prior to the Big Deal if the last trader with the item elected to choose one of the three doors).
- A variation of the above: A "cash box", with at various points the host inserting packets of money inside, with the contestant allowed to give it to another trader in exchange for a curtain or box. As with the above deal, the host only revealed the contents only after the last trader with the box goes for the Big Deal (again, he/she is given first choice of the doors) or after the Big Deal segment and before the closing credits.
Games of chance
Games of chance range wide in variety and format:
- Collecting a certain amount of money hidden inside wallets, envelopes, etc., or by pressing unlabeled buttons on a cash register, in order to reach a pre-stated "selling price" for a larger prize, such as a car, trip or larger amount of cash. Typically, there may also be one or more Zonk items hidden which end the game immediately if found. In the cash register game, if the Zonk button—the one that rings up "No Sale" – is found, the contestant was offered a chance to find the second "No Sale" sign to win the grand prize, otherwise the contestant won whatever amount was rang up, often double the amount. Updated versions of the game involve an ATM motif, where depositing a card withdraws cash, but "Overdrawn" on the screen counts as a Zonk and costs the player everything.
- Choosing one from among several items (e.g., one of three keys that unlocks a safe, one of three diamond rings that is genuine, one of three eggs that is raw, etc.) in order to win money or a prize. Sometimes, two or perhaps all three of the items would pay off with the state prize, especially if multiple contestants played.
- Games involving a deck of cards in which a trader must find matching cards, draw cards that reach a cumulative total within a certain number of draws, etc. to win a prize or additional money.
- Receiving clues about an unknown prize (such as a partial spelling of the prize or clues in the form or rap, rhyme, etc.) and deciding whether to take the unknown prize or a cash prize.
- Rolling dice to receive cash based upon the roll or achieving a cumulative score within a certain number of rolls to win a larger prize.
Depending on the game, the contestant is given the opportunity to stop the game at various points and take a "sure thing" deal or cash/prizes already accumulated or continue on and risk possibly losing.
Beat the Dealer
"Beat the Dealer" is a game played with three players. The three contestants choose a card from a board of nine cards to begin the game. The contestant selecting the lowest-ranked card is eliminated (and wins $100), while the other two receive $500. In the second round, a prize package is shown to the contestants. The two advancing players select two more cards. Same elimination rules apply, with the contestant having the higher card winning the prize package in addition to advancing to the final round. The remaining contestant could quit with their winnings so far or risk them in an attempt to add a car. If the contestant chose to play, he or she selected a card for himself or herself, and one for the host. Before the draw, the contestant was given the option to assign the card to either themself or the host. If the contestant again chose the higher card, he or she won all the prizes announced, but the lower card would forfeit all prizes.
Prior to 2011, the three contestants each choose an envelope which contained cash (two each of $500 or $1,000, depending on the version; with the third containing $50 or $100). The contestant who found the smaller amount was eliminated, while the other two advanced to the second round.
Other deals related to pricing merchandise are featured in order to win a larger prize or cash amounts. Sometimes traders are required to price individual items (either grocery products or smaller prizes generally valued less than $100) within a certain range to win successively larger prizes or a car. Other times traders must choose an item that a pre-announced price or two items with prices that total a certain amount to win a larger prize. These games are not used on the CBS version because of their similarities to The Price is Right.
Other deals are related to products in the form of when they were introduced to the market, general knowledge quizzes, or knowledge of geography of trips to certain locales used as prizes. These games are often used on the CBS version.
Door #4/Go for a Spin
Played every few days on the 1984–86 version, a trader was chosen at random by a computer based on a number (from 1–36) which appeared on the trader's name tag. The rules were revised several times in early playings, with the rules most associated with the game going into effect by later in the fall of 1984.
Those most common rules saw Hall give the contestant a check for $1,000 and then offered an opportunity to spin a carnival wheel, containing amounts ranging from $100 to $4,000, plus several spaces marked "Zonk." Two other spaces were marked with the word "car", which won a new car if landed on. The contestant could either keep the $1,000 or exchange it for spinning the wheel. Wherever the wheel landed on, that's what the contestant won; if the wheel stopped on a "Zonk" space, he/she received a T-shirt saying "I was ZONKED by Monty Hall." Even if the contestant decided to keep the initial $1,000, he she was asked to spin the wheel to see how the game would have ended.
In the first playings, the trader was offered a sure-thing prize package or going for Door #4, which hid a cash amount of anywhere from $1–$5,000. When the carnival wheel was initially introduced, the wheel contained cash amounts from $100–$5,000. The trader spun the wheel and could keep the cash amount on which the wheel stopped, or risk their winnings for another spin. However, if the amount of the second spin was less than the first amount spun, the trader won nothing. Also on the wheel was a space marked "Double Deal", which doubled the trader's spin, for a possible total of $10,000. If the trader spun Double Deal with both spins, they also won $10,000. When the permanent rules were first introduced, the initial cash prize was $750, with the wheel's top cash prize at $3,000.
A revamped version, titled "Go for a Spin", was first played on the December 20, 2011 episode. A contestant is selected and shown a sixteen-space wheel, with various cash amounts, five Zonk spaces and one car space. The trader is then asked three questions with two choices each, and attempts to choose the option preferred by the audience in an earlier poll. For each correct choice selected, the trader wins $500 and one Zonk space of the trader's choice is converted to a car space. The trader can keep the money earned or trade it in for one spin of the wheel. If the trader chooses to spin, the trader wins whatever is indicated in the space on which the wheel stops.
Each show ends with the Big Deal. Beginning with the day's biggest winner, and moving in order to the winner of the lowest prize value, the host asks each trader if they want to trade their winnings for a spot in the Big Deal (whose value was usually revealed at that point). He continues asking until two traders agreed to participate. However, in the CBS version, only one trader is asked to participate in the Big Deal.
The Big Deal involves three doors, famously known as "Door #1", "Door #2", and "Door #3", each of which contains a prize or prize package. In the two-trader format used until 2003, the top winner of the two was offered the first choice of a door, and the second trader was then offered a choice of the two remaining doors. In the one-trader format used since 2009, the trader simply selects a door.
One door hides the day's Big Deal, which is usually valued higher than the top prize offered on that specific episode to that point. It often includes the day's most expensive prize (a luxury or sports car, a trip, furniture/appliances, a fur, cash, or a combination of items). The other two doors conceal prizes or prize packages of lesser value. The Big Deal does not offer Zonks, although there is always the possibility that a trader could wind up with less than their original winnings. All three doors are opened, in order of increasing value; however, the order of reveal often changes on the CBS version based upon the trader's selection.
Sometimes one of the doors contains a cash prize, contained within a container such as "Monty's Cookie Jar", "Monty's Piggy Bank", a "LMaD Claim Check", or in the CBS version, the "Let's Make a Deal Vault". In some cases these cash prizes have been the Big Deal, but often they are not.
During the 1975–76 syndicated season, a new "Super Deal" was offered for Big Deal winners. At this point, Big Deals were limited to a range of $8,000 to $10,000. The trader could risk their Big Deal winnings on a 1-in-3 shot at adding a $20,000 cash prize. A trader who chose one of the other doors forfeited the "Big Deal", but received a $1,000 or $2,000 consolation cash prize. Given this scenario, a Super Deal winner could win as much as $30,000 in cash and prizes. Later, the consolation cash prize was changed to $2,000 and a "mystery amount" between $1,000 and $9,000.
The Super Deal was discontinued when the show permanently moved to Las Vegas for the final season (1976–77), and Big Deal values returned to the previous range of $10,000 to $15,000.
The Super Deal returned on March 26, 2012 on the CBS version in celebration of its 500th episode that day and again on February 18, 2013 to celebrate the show's 50th anniversary and each Super Deal lasted for two weeks and again on the week of April 22nd. Three envelopes, ruby, emerald, and sapphire, hid cash prizes of $1,000, $2,000, and $50,000. As before, if the $50,000 envelope was chosen, the contestant won the cash and kept their Big Deal.
Upon the original Let's Make a Deal's debut, journalist Charles Witbeck was skeptical of the show's chances of success, noting that the previous four NBC programs to compete with CBS' Password had failed. Some critics described the show as "mindless" and "demeaning to contestants and audiences alike."
By 1974, however, the show had spent more than a decade at or near the top of daytime ratings, and became the highest-rated syndicated primetime program. At the time, the show held the world's record for the longest waiting list for tickets in show-business history – there were 350 seats available for each show, and a wait time of two-to-three years after requesting a ticket.
In 2001, Let's Make a Deal was ranked as #18 on TV Guide's list of "The 50 Greatest Game Shows of All Time." In 2006, GSN aired a series of specials counting down its own list of the "50 Greatest Game Shows of All Time", on which Let's Make a Deal was #7.
Many of the show's estimated five thousand plus episodes exist:
- NBC Daytime/Nighttime: Status is unknown, though it is very likely that the original tapes were wiped as they were recorded over by NBC with new programming in an era when videotape was prohibitively expensive. The 1963 pilot exists, with Wendell Niles as announcer, traders in normal business attire (typical of its first season), and a Zonk behind one of the doors in the Big Deal (worth $2,005). Zonks have never officially been in the big deal. The 1967 nighttime finale exists in the Library of Congress, along with a few scattered daytime episodes. Three daytime episodes are at the Paley Center for Media. Clips of the pilot and others were used in 2013 for both flashback clips and also during the opening clip montage used in the show opening.
- ABC Daytime: More than 500 episodes exist. A clip from the ABC daytime premiere was used on Monty Hall's "Biography", which aired during Game Show Week on A&E. Another episode from 1969 was found, which features a gaffe that Hall himself rated as his most embarrassing moment on Let's Make a Deal – at the end of the show, he attempted to make a deal with a woman carrying a baby's bottle. Noting that it had a removable rubber nipple, he offered the woman $100 if she could show him another nipple (she didn't). This clip was restored utilizing the LiveFeed Video Imaging kinescope restoration process, and was re-aired in 2008 as part of NBC's Most Outrageous Moments series. Episodes substitute-hosted by Dennis James exist in his personal library; a clip from one of his episodes was featured in a 1972 pitch film for The New Price Is Right, whose nighttime version was hosted by James.
- ABC Nighttime/1971–77 Syndicated: Exist almost in their entirety and have been seen on GSN in the past. The CBN Cable Network reran the syndicated series in the 1980s and its successor, The Family Channel, from June 7, 1993 to March 29, 1996.
- (NOTE: All episodes exist from 1980 onward. The original 1964–77 (NBC, ABC, Syndicated), 1980, and 1984 version logos were included in the show opening sequence in the 2013 50th anniversary episodes.)
- The 1980–81 Canadian version was seen in reruns on the Global Television Network for much of the 1980s.
- The 1984–86 syndicated version has been seen on GSN in the past. Reruns previously aired on the USA Network from December 29, 1986 to December 30, 1988 and The Family Channel from August 30, 1993 to March 29, 1996.
- The 1990s NBC version has not been seen since its cancellation. The logo of this version was not included in the 50th anniversary opening.
- The 2003 NBC prime time version only aired three of the five episodes produced, with no rebroadcasts since. The logo of this version was not included in the 50th anniversary opening.
RTL Group holds international (and as of February 2009, American) rights to the show, and has licensed the show to 14 countries.

In 1964, Milton Bradley released a home version of Let's Make a Deal featuring gameplay somewhat different from the television show. In 1974, Ideal Toys released an updated version of the game featuring Hall on the box cover, which was also given to all traders on the syndicated version in the 1974–75 season. An electronic tabletop version by Tiger Electronics was released in 1998. In the late summer of 2006, an interactive DVD version of Let's Make a Deal was released by Imagination Games, which also features classic clips from the Monty Hall years of the show. In 2010, Pressman Toy Corporation released an updated version of the box game, with gameplay more similar to the 1974 version, featuring Brady on the box cover.
In 1999, Shuffle Master teamed up with Bally's to do a video slot machine game based on the show with the voice and likeness of Monty Hall.
In 2004, IGT (International Gaming Technology) did a new video slot game based on the show still featuring Monty Hall.
In 2013, Aristocrat Technology did an all-new video slot machine game based on the Wayne Brady version.
The Monty Hall Problem
The Monty Hall Problem, also called the Monty Hall paradox, is a veridical paradox because the result appears impossible but is demonstrably true. The Monty Hall problem, in its usual interpretation, is mathematically equivalent to the earlier Three Prisoners problem, and both bear some similarity to the much older Bertrand's box paradox. The problem examines the counterintuitive effect of switching one's choice of doors, one of which hides a "prize."
The problem has been analyzed many times, in books, articles and online. In an interview with The New York Times reporter John Tierney in 1991, Hall gave an explanation of the solution to that problem, stating that he played on the psychology of the contestant, and why the solution did not apply to the case of the actual show.
