The game of blackjack is originated from French casinos in around 1700 where it was called as “vingt-et-un” (“twenty-and-one”). The origin of this game in US can be traced since 1800. The name Blackjack is given to this game because if the player got a Jack of Spades and an Ace of Spades as the first two cards (Spade being the color black of course), the player was additionally remunerated.
