It is not clear which is its precise source, but the most established hypothesis establishes the European origin of blackjack in France in the casinoin the 12th century. It is thought that French citizens played a game known as vingt et un, which is translated as twenty-one, in the rooms of noble lords. The object of the casino game was to obtain 21 points with only two cards.

In case a player obtained more than 21, the player immediately lost the game. The arrival of blackjack to the United States, more particularly to the casinos in Las Vegas took place when the immigrants brought it from Europe. In 1931, in a town in Nevada blackjack made history when it was legalized, establishing itself as one of the main casino games.

Another fact that made history in the game of blackjack took place in 1962, when Edward Thorp used a primitive digital device to analyze the typical distribution of blackjack hands in blackjack games.

Making use of his investigation, he developed what is currently known as basic blackjack strategy and in this way he managed to become famous and gave this casino game more popularity. Currently, blackjack has lots of followers and is an essential part of casinos.
