Blackjack originated as "Vingt-et-Un" in 17th-century France, focusing on reaching 21 points. It spread to the U.S., where it evolved with new rules, such as doubling down and splitting pairs, adding strategic elements. The term "blackjack" was coined in the U.S. when casinos offered bonuses for specific hands. Over time, standardized rules emerged, and multiple game variants were created to enhance player appeal. Technological advancements, including automatic shuffling and online platforms, have further transformed blackjack, making it widely accessible while preserving its core blend of skill and chance. Today, it remains a popular casino staple worldwide.
