The History of Black Jack
It´s exact origins are unknown, but a variety of games are likely to have developed in which the objective was not to exceed a specified number of points. Today's Black Jack is still most similar to the French game "Vingt-et-Un", translated "21". At the end of the 19th century it acquired the name "Twenty-One" in the US, where it was played primarily in private rounds. Then after 1900 American casinos also began to offer it, though in the beginning it was less popular. Only after a few changes in the rules did Black Jack make quick gains in popularity, which is unbroken today.
