Early blackjack, originating as “Vingt-et-Un” in France, had simpler rules, focusing on reaching 21 without specific betting or payout structures. There were no options like splitting, doubling down, or insurance. Over time, casinos introduced these features, along with standardized payouts, to make the game more strategic and appealing. The role of the dealer also evolved, with fixed rules for hitting or standing, while rules for card-counting were introduced to prevent players from gaining an unfair advantage. Today’s blackjack is more complex, blending elements of chance and strategy that make it distinct from its origins.
