Three-card Monte – also known as Find the Lady and Three-card Trick – is a confidence game in which the victims, or "marks", are tricked into betting a sum of money, assuming they can find the "money card" among three face-down playing cards.

The Three-card Monte game is simple to play. A dealer places three cards face down on a table and shows that one of the cards is the target card, e.g., the queen of hearts, and then rearranges the cards quickly to confuse the player about which card is which. The player is then given an opportunity to select one of the three cards. If the player correctly identifies the target card, the player gets the amount bet (the "stake") back, plus the same amount again; otherwise, the stake is lost.
