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.

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: the combination that makes a greater number becomes a winning one. But it shouldn’t be beyond 21.

Though, 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. This technique consists 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.

One of the best ways of enjoying free blackjack games is attending various tournaments in online casinos. The most popular tournaments and championships are carried out for blackjack and slot machines.

So, how are these blackjack tournaments held?

It's simple: casino announces the tournament, informs about the beginning and the end of the tournament. Then it determines the minimal bet and distributes the prize money.

In offline game all players play simultaneously at common tables. But online game differs - everyone plays on their own accounts, as in a normal game. And this is your trump card, because none of your opponents can see your emotions while you play online.

The player's task is to collect more money than the other participants do. The tournament lobby displays the current leaders, so that you can always evaluate your position relatively to opponents.

Usually, online casinos offer their players to attend the monthly tournaments instead of getting deposit bonuses.

All tournaments are usually sponsored by a casino, so that gamblers can enjoy their free blackjack games without taking a risk to lose money.
