As with many other games, no one knows exactly the origin of Blackjack. Most agree it was introduced in French casinos in around 1700, where it was known as "Vingt-et-Un", which is french for Twenty-one.
Most believe that BlackJack is a variation of Baccarat, as the object of the game is somewhat similar, which is to add up the cards in your hand.
