Blackjack (also known as Twenty-one) is a card game popular in casinos.
When playing blackjack, the dealer faces one to seven players. Each player plays his hand separately against the dealer. The part opposes all the players against the bank. The goal is to approach or make 21 without exceeding them. As soon as a player exceeds 21 it is said that it “jumps” or that it “bursts” and it loses his initial setting. The value of the charts is established as follows:
from 2 to 10 -> face value of the chart
each figure -> 10 points
the Ace -> 1 or 11 (with the choice)
Blackjack is made thanks to Have and a “log” (chart having for value 10, therefore 10, J, Q or K). However, if the player reaches item 21 in 3 charts or more one counts item 21 and not Blackjack. To the beginning of the part, the croupier distributes a chart face visible with each player and also draws a chart visible face for him. He then draws for each one one second visible chart face and car one second chart hidden side for him (American Blackjack).
Then he asks to the first player of the table (player located on its left) the option which it wishes to choose. If the player wants a chart, it must announce it by saying “Chart!”. The player can ask as many charts as it wishes it. So after the pulling of a chart, it exceeded 21, it loses its setting and the croupier passes to the following player. If it decides to stop, while saying “I remain”, the croupier also passes to the following player.
The croupier repeats this operation until all the players are served.
Then he plays for him according to a simple and codified rule: “The bank draws to 16, remains to 17”. As you included/understood, the croupier draws from the charts until reaching a point ranging between 17 and 21. If it makes more than the 21 all remaining players gain and if it makes its point, only those gain having a point higher than his (without to have jumped). In this situation, the player gains the equivalent of his setting. In the event of equality the player keeps his setting but empoche nothing moreover.
After the distribution of the first charts, the player can use other possibilities of the play:
Insurance. If the first chart of the croupier is Have, a player with the possibility of insuring itself against its Blackjack. In fact, the player must pay half of his initial setting. If the croupier makes Blackjack, the player loses his setting but sees himself paid the insurance (thus benefit 0, loss 0). If the croupier does not make Blackjack two situations are possible: firstly, the player gains. He loses his insurance but empoche the equivalent of his initial setting (clear benefit: 1/2 of the initial setting). Secondly, the player loses. He then loses the insurance like his setting (loss: 1,5 times the initial setting).
The split. When a player obtains two charts of same value, it is possible for him to separate these two charts in order to play with two plays. For that, it must add the same setting as that which it played at beginning. Once the separated plays, the player plays each hand in the same way that a simple hand. If it gains on the two plays, it will have killed two birds with one stone (two profits in a blow). If the player loses on a play, it does not gain but does not lose anything.
Lastly, if it loses on the two plays, it will have lost twice in a blow. It should be noted that so following a separation, the player obtains a third of the same chart value (on the first or second table) it can again separate them and thus play on 3 tables. In the French casinos it is not possible to play on more than three tables.
A particular rule relates to the separation of two aces: by separating two aces, the player cannot receive any more but one chart for each table.
Double. After having received two charts, the player can choose to double his setting in the only condition of receiving only one chart after that. Example: after gives, I have 11 (8 and 3). The croupier has a weak chart, 6 for example. I choose to double my setting and I receive a log. I find myself with item 21 (and not Blackjack) whereas the croupier has very few chances to make his point.
In American Blackjack, the player doubles hidden side (doubling down), i.e. the chart which it receives after having doubled to him is distributed hidden side. He sees it only once the play of the finished croupier.
