Blackjack is one of the most popular gambling games nowadays, played both in land based and online casinos.
Blackjack has a quite rich history that begins in the XVIII century in France. It is considered that the predecessor of this game was a card game «vingt-et-un» («twenty-one»), which appeared in the French gambling establishments approximately in the XIX century.
21- Game with the Name
Today, in most of CIS countries it is called simply “21”. This name is directly associated with the most successful combination in the hands of a player.
So, modern blackjack differs significantly from its progenitor, which was played in the beginning of the XVIII century.
It is interesting that the basic rules have not changed significantly: the combination that makes a greater number becomes a winning one. But it shouldn’t be higher than 21.

Card Counting - Blessing or Curse?
In order to make their chances better, many players use a method for tracking card in the deck (shuffle tracking), which allows to improve their chances of winning in case of professional approach. The principle of this technique lies in the fact that a player visually sees where (in what parts of the deck) the interested cards are placed. And on the basis of these data the player takes gaming and betting solutions.
Thus, after summarizing the great mathematical base for blackjack, casino owners were forced to complicate the rules in order to reduce the possibility of "card counting" (the so-called operation of mathematical definition of a winning combination without the risk of loss) to a minimum.
