Blackjack is most often played with six decks of French cards (the number may vary from 1 to 8),each deckconsists of 52 cards - from a two to an ace in four suits (including 2 black - spades and clubs and 2 red – hearts and diamonds). Cards 2-10 have their face value, the cards from jack to a king are worth 10 points and an ace is worth a variable value of 1 or 11. An ace has the ability to create so-called "soft" combinations, which practically means that, given an ace and 8 the total can be either of 9 or 19. In this case it means soft 19. This value of the combination at the start of the hand counts as 19, but if a player drew another card and the sum exceeded 21, the value of the ace is reduced to 1, thus the cards – ace and a seven would make 18. If then an 8 was drawn, the value of the ace would automatically become 1, making the hand worth 16.
Blackjack is played against the dealer with the player aiming to obtain a higher value hand than the dealer, but not exceeding the value of 21. If you exceed 21, the game is over regardless of the sum the dealer has reached. If the dealer exceeds the limit of 21, the player wins.
The basic win in blackjack is in the ratio of 1:1. If the player gets a combination of an ace and a card worth 10, the player receives a reward for blackjack usually in the ratio of 3: 2 (the bet of 1 € would win € 2.50).
There is also a rule that after reaching the sum of 17, the dealer does not draw another card. However, the soft 17is not automatic. This rule may be applied differently i.e. when reaching the value of soft 17 the dealer draws another card or has to stand. If you play online, the table always (follows a particular set of rules) carries the instruction on the rules applied. Usuallythe instruction says "dealer stands at soft 17" and "blackjack pays 3 to 2".
If you happen to come across a Blackjack type, where the blackjack is rewarded at a ratio lower than 3: 2 (mostly when playing with only one or two packs of cards), you should be aware that casino’s edge is much higher when this rule is applied.
