How “crabs” became “craps”

The name craps is linked to an English dice-game term: “crabs,” a name for especially bad throws. In Louisiana, French-speaking players adopted the English term and pronounced it in a way that turned the final b sound into a p. The altered word stuck as the name of the game.

That small sound change reflects a larger exchange. Dice games traveled between languages and communities, and players carried their own words for throws and rules along with them. As the game took root in Louisiana, its name preserved a trace of that contact.

From a bad throw to a game name

The connection makes sense because dice outcomes are central to craps. Players bet on what will happen as dice are rolled, so a term for an unlucky result could readily become associated with the game itself. Over time, the reference to “crabs” gave way to the familiar name, “craps.”

The result is a casino staple whose name records more than its rules: it captures a moment when an English gaming expression passed through Louisiana French and emerged with a different sound.
