The game concept in Blackjack is relatively simple. It's about beating the dealer and getting closest to the number 21 without getting into a number over it, using cards that are dealt to you. Even if you are several players at a Blackjack table, you only play against the dealer in each dealer. So it doesn't matter if more than you win in one and the same round as you still get your entire win. A Blackjack round of bets will allow you to bet on your hand even before the cards are dealt, and then as a player you will receive two open cards while the dealer receives one. It is now up to you to consider whether you want one to short or if you want to stay. Only after that does the dealer draw another card. To win you must have a higher total than the dealer, but not above the number 21 in total. The dealer must stay at 17 or higher and must not stop pulling cards until it has landed there. If you or the dealer gets over 21, the game is lost and the counterparty has won. If you end up at between 17 to 19, the dealer wins but if you get 20 or 21 you split the pot. Then as a player you have neither won nor lost. The hand known as Blackjack, an Ace and a Jack wins directly against other hands.
If this was the whole game then it would have been an easy one with maybe not as fascinating games as it is now. Over the years, Blackjack has become much more versatile and nowadays there are several game variants at different casinos. To prevent cheating or card counting, you now play with more than one deck of cards. In fact, you can use up to eight games in some casinos, but the most common is that you settle for two to four. As a player, you need to make certain choices: hit, stand, double down and split. This means you take one more card, on stand you stop on your two cards. With a double down, you double your stake and draw one more card while a split lets you split two equal cards into two different hands.BlackjackThe dealer never uses either split or double down, and different casinos have different rules for how these hands should be played. The value of the cards is calculated by numbering, the cards are automatically ten and an ace can be worth one or eleven.
Since Blackjack has been around for hundreds of years, people for generations have been trying to find the way to outwit the house and guarantee a profit. If you have seen movie 21 you have heard of card counting and the fact is that this movie is based on a true story. There, you can follow top students from one of the most prestigious tech universities in the US who capped Vegas and picked up huge sums on a Blackjack game using card counting and probability theory. This scandal is one of many reasons for the small but necessary rule changes in Blackjack and a contributing reason why one often plays with many card games.
