Press Your Luck is an American television game show created by Bill Carruthers and Jan McCormack. Contestants answer trivia questions to earn "spins" on a randomly cycling game board. The board's spaces display cash, prizes, extra spins, special items, or the show's mascot, a cartoon creature known as the Whammy. Landing on a Whammy eliminates any cash and prizes accumulated while also displaying a short comedic animation. Its format is a revival of an earlier Carruthers production, Second Chance, which was hosted by Jim Peck and aired on ABC in 1977. The original version of Press Your Luck aired on CBS between 1983 and 1986. This version featured Peter Tomarken as host, Rod Roddy as announcer, and Carruthers as both director and voice of the Whammy. The original incarnation of the show gained significant media attention in 1984 for contestant Michael Larson, who won over $100,000 after memorizing the original pattern of the game board.

Following the show's cancellation by CBS in 1986, it aired frequently in reruns, first on USA Network and then on Game Show Network. Whammy! The All-New Press Your Luck, a revival of the series, aired from 2002 to 2003 also on Game Show Network with Todd Newton as host and Gary Kroeger as announcer. A weekly primetime version (reverting to the name Press Your Luck) began airing on ABC in 2019, with Elizabeth Banks as host. Neil Ross served as both announcer and voice of the Whammy until 2023, when he was replaced in both capacities by Chris Ahearn. Adaptations of Press Your Luck have also aired in other countries such as Australia, the United Kingdom, and Germany, while an adaptation of Whammy! The All-New Press Your Luck also aired in the Philippines. The show has also been adapted into a number of video games for computers and video game consoles.
