Blackjackalso known as twenty-oneis a comparing online blackjack javascript game between usually several players and a dealer, where here player in turn competes against the dealer, but players do not play against each other. It is played with one or more decks of 52 cards, and is the most widely played casino banking game in the world. The objective of the game is to beat the dealer in one of the following ways:.

Players are each dealt two cards, face up or down depending on the casino and the table at which you sit. In most other countries, the dealer receives one card face up. The value секунд new jersey online gambling blackjack для cards two through ten is their pip value 2 through Face cards Jack, Queen, and King are all worth ten.

Aces can be worth one or eleven. A hand's value is the sum of the card values. Players are allowed to draw additional cards to improve their hands. A hand with an ace valued as 11 is called "soft", meaning that the hand will not bust by taking an additional card; the value of the ace will become one to prevent the hand from exceeding Otherwise, the hand is "hard". The dealer hand will not be completed if all players have either online blackjack javascript or received Blackjacks.

The dealer must hit until the cards total 17 or more points. At most tables the online blackjack javascript also hits on a "soft" 17, i. Players win by not busting and having continue reading total higher than online blackjack javascript dealer, or getting a blackjack without the dealer getting a blackjack.

If the player and dealer have the same total not counting blackjacksthis is called a "push", and the player typically does not win or lose money click that hand. Otherwise, the dealer wins. Blackjack has many rule variations. Since the s, blackjack has been a high-profile target online blackjack javascript advantage playersparticularly card counterswho track the profile of cards that have been dealt and adapt their wagers and playing strategies accordingly.

Blackjack has inspired other casino games, including Spanish 21 and pontoon. Blackjack's precursor was twenty-onea game of unknown origin. The first written reference is found in a book by the Spanish author Miguel de Cervantesmost famous for writing Don Quixote.

Cervantes was a gamblerand the main characters of his tale " Rinconete y Cortadillo ", from Novelas Ejemplaresare a couple of cheats working in Seville. They are proficient at cheating at veintiuna Spanish for twenty-one online blackjack javascript, and state that the object of the game is to reach 21 points without going over and that the ace values 1 or The game is played with the Spanish baraja deck, which lacks eights and nines.

Online gambling nj sports short story was written between andimplying online blackjack javascript ventiuna was online blackjack javascript in Castilla online blackjack javascript the beginning of the 17th century or earlier. Later references to this game are found in France and Spain. When twenty-one was introduced in the United States, gambling please click for source offered bonus payouts to stimulate players' interest.

One such bonus was a ten-to-one payout if the player's hand consisted of the ace of spades and a black jack either the jack of clubs or the jack of spades.

This hand was called a "blackjack", and the name stuck to the game even though the ten-to-one bonus was soon withdrawn. In the modern game, a online blackjack javascript refers to any hand of an ace plus a ten or face card regardless of suits or colours.

The first scientific and mathematically sound attempt to devise an optimal blackjack crown europe strategy was revealed in September This paper would become the foundation of all future sound efforts to beat the game of blackjack. At a casino blackjack table, the dealer faces five to seven playing positions from behind a semicircular table. Between one and eight standard card decks are shuffled together.

At the beginning of each online blackjack javascript, up to three players can place their bets in the "betting box" at each position in online blackjack javascript. That is, there could be up to three players at each position at a table online blackjack javascript jurisdictions that allow back betting. The player whose bet is at the front of the betting box is deemed to have control over the position, and the dealer will consult the controlling player for playing decisions regarding the hand; the other players of that box are said to "play behind".

Any player is usually allowed to control or bet in as many boxes as desired at a single table, but it is prohibited for an individual to play on more than one table at a time or to place multiple bets within a single box. Each box is dealt an online blackjack javascript hand of two cards visible to the people playing on it, and often to any other players.

The dealer's hand receives its first card face up, and in online blackjack javascript card" online blackjack javascript immediately receives its second card face down the hole cardwhich the dealer online blackjack javascript at but does not reveal unless it makes the dealer's hand a blackjack.

Hole card games are sometimes played on tables with a small mirror or electronic sensor that is used to peek securely at the hole card. In European casinos, "no hole card" games are prevalent; the dealer's second card is neither drawn nor consulted until the players have online blackjack javascript played their hands.

Cards online blackjack javascript dealt either from one or two handheld decks, from a dealer's shoeor from a shuffling machine.

Single cards are dealt to each wagered-on position clockwise from the dealer's left, followed by a single card to the dealer, followed by an additional card to each of the positions in play.

The players' initial cards may be dealt face up or face down more common in single-deck games. On their turn, players must choose whether to "hit" take a card"stand" end their turn"double" double wager, take a visit web page card and finish"split" if the two cards have the same value, separate them to make two hands or "surrender" give up a half-bet and retire from the game.

Number cards count as their natural value; the jack, queen, and king also known as "face cards" or "pictures" count as 10; aces are valued as either 1 or 11 according to the player's choice. If the hand value exceeds 21 points, it busts, and all bets on it are immediately After all boxes have finished playing, the dealer's hand is resolved by drawing cards until the hand busts or achieves a value just click for source 17 or higher a dealer total of 17 including ace, or "soft 17", must be drawn to in some games and must stand in others.

The dealer never doubles, splits, or surrenders. If the dealer busts, all remaining player hands win. If the dealer does not bust, each remaining bet wins if its hand is higher than the dealer's, and loses if it is lower. If a player receives 21 on the 1st and 2nd card it is considered a "natural" or "blackjack" and the player is paid out immediately unless dealer also has a natural, in which case the hand ties.

In the case of a tied score, known as "push" or "standoff", bets are normally returned without adjustment; however, online blackjack javascript blackjack beats any hand that is not a blackjack, even one with a value of Wins are paid out at 1: Many casinos today pay blackjacks at online blackjack javascript than Blackjack games almost always provide a side bet called insurance, which may be played when dealer's upcard is an ace.

Additional side bets, such as "Dealer Match" which pays when the player's cards match the dealer's up card, are sometimes click to see more. After receiving an initial two cards, the player has up to four standard options: Each option has a corresponding hand signal. Some games give the player a fifth option, "surrender".

Hand signals are used to assist the " eye in the sky ", a person or video camera located above the table and sometimes concealed behind one-way glass. The eye in the sky usually makes a video recording of the table, which helps in resolving disputes and identifying dealer mistakes, and is also used to protect the casino against dealers who steal chips or players who cheat.

The recording can further be used to identify advantage players whose activities, while legal, make them undesirable customers. In the event of a disagreement between a player's hand signals online blackjack javascript their words, the hand signal takes precedence.

Each hand may normally "hit" as many times online blackjack javascript desired so long as the online blackjack javascript is not above hard On reaching 21 including soft 21the hand is see more required to stand; busting is an irrevocable loss and the players' wagers are immediately forfeited to the house. After a bust or a stand, play online blackjack javascript to the next hand clockwise around the table.

When the last hand has finished being played, the dealer reveals the hole card, and stands or draws further cards according visit web page the rules of the game for dealer drawing. When the outcome of the dealer's hand is established, any hands with bets remaining on the table are resolved online blackjack javascript free casino game online counterclockwise order: If the dealer's upcard is online blackjack javascript ace, the player is offered the option of taking "insurance" before the dealer checks the hole card.

Insurance is a side bet that the dealer has blackjack and is treated independently of the main wager. The idea is that the dealer's second card has a fairly high probability nearly one-third to be ten-valued, giving the dealer blackjack and disappointment for the player. It is attractive although not necessarily wise for the player to insure against the possibility of a dealer blackjack by making a maximum "insurance" bet, in which case the "insurance proceeds" will make up for the concomitant loss on online blackjack javascript original bet.

The player may add up to half the value of online blackjack javascript original bet to the insurance and these extra chips are placed on a portion of the table usually marked "Insurance pays 2 to 1". Players with a blackjack may online blackjack javascript take insurance, and in taking maximum insurance they commit themselves to winning an amount exactly equal to their main wager, regardless of the dealer's outcome.

Fully insuring a blackjack against blackjack is thus referred to as "taking even money", and paid out immediately, before the dealer's online blackjack javascript is resolved; the players online blackjack javascript not need to online blackjack javascript more chips for the insurance wager. Insurance bets are expected to lose money in the long run, because the dealer is likely to have blackjack less than one-third of the time. However the insurance outcome is strongly anti-correlated with that of the main wager, and if the player's priority is to reduce variationthey might choose to pay for this.

Furthermore, the insurance bet is susceptible to advantage play. It is advantageous to make an insurance bet whenever the hole card has more than a chance of one in three of being a ten. Advantage play techniques can article source identify such situations.

In a multi-hand, face-up, single deck game, it is possible to establish whether insurance is a good bet simply by observing the other cards on online blackjack javascript table after the deal; even if there are just 2 player hands exposed, and neither of their two initial online blackjack javascript is a ten, then 16 in 47 of the remaining cards are tens, which is larger deposito bonus codice bwin di 1 in 3, so online blackjack javascript is a good bet.

This is an elementary example of the family of advantage play techniques known as card counting. Bets to insure against blackjack are slightly less likely to be advantageous than click to see more bets in general, since the ten in the player's blackjack makes it less likely that the dealer has blackjack too.

The rules of casino blackjack are generally determined by law or regulation, which establishes certain rule variations allowed at the discretion of the casino. The rules of any particular game are generally posted on or near the table, failing which there online blackjack javascript an expectation that casino staff will provide them on request. Over variations of blackjack have been documented. As with all casino games, blackjack incorporates a "house edge", a statistical advantage for the casino that is built into just click for source game.

The advantage of the dealer's position in blackjack relative to the player comes from the fact that if the player busts, the player loses, online blackjack javascript of whether the dealer subsequently busts. The loss online blackjack javascript of players who deviate from basic strategy through ignorance is generally expected to be greater. Surrender, for those games that allow it, is usually not permitted against a dealer blackjack; if the dealer's first card online blackjack javascript an ace or ten, the hole card is checked to make sure there is no blackjack before surrender is offered.

This rule protocol is consequently known as "late" surrender. The alternative, "early" just click for source, gives player the option to surrender before online blackjack javascript dealer checks for blackjack, or in a no-hole-card game.

Early online blackjack javascript is much more favorable to the player than late surrender. Most medium-strength hands should be surrendered against a dealer Ace if the hole card has not been checked.

For late surrender, however, while it is tempting to opt for surrender on any hand which will probably lose, the correct strategy is to only surrender on the very worst hands, because having even a one in four chance of winning the full bet is better than losing half the bet and pushing the other half, as entailed by surrendering.

Blackjack - Wikipedia

First, take a break and play the game to get an idea of how it works. You'll see that various elements on the page are dynamically updated, added and removed during the course of play. Be sure to read the rules provided. It will help in understanding much of the article source flow and comments in the rest of this article.

Games necessarily require a online blackjack javascript deal of interaction and dynamic content. As it is a fairly large script, some details of the code are omitted. The comments in the source should help explain the finer points and other articles on this site provide good information on many of the techniques used, particularly on using CSS and the DOM.

First there are the areas for the dealer and player made up of a main DIV tag containing other DIVs for the cards and text messages. Http:// style class textBox specifies float: The card area is initially empty but will be filled and cleared dynamically online blackjack javascript the game is played.

Although the game is designed for a click player, it does allow "splits. Likewise, either of these can be split again if another pair is dealt. To accommodate this, three other sets of DIVs are defined in the code. These are exactly like the main player's area except for the the IDs assigned to each online blackjack javascript. The rules limit the player to a maximum of three splits in any round so three additional areas are needed.

As they are usually not used, they have an inline style specifying display: Should the player split a hand, this style setting will be changed programmatically to display the an area and likewise, set to display: Online blackjack javascript the playing areas is a form with several buttons. Each has a function assigned to it using the onclick event to allow click to see more player to take various actions during play.

Some buttons are initially disabled. During the course of the game, individual buttons will be dynamically enabled or disabled by the script depending on various circumstances. This way, the user will only be able online blackjack javascript choose from whatever options are valid online blackjack javascript any given point in the game. For example, the player can only surrender at the start of a round when the first two cards are dealt.

Should the player just click for source to hit, stand or take any other option instead, the "Surrender" button is disabled for the remainder of the round. This helps reduce the amount of code needed as we don't have to check if a given action is valid online blackjack javascript time.

It also helps the user by giving a visual clue at to what options are available at any given time. To the right of the control buttons are two more DIVs for displaying the player's current credit line and and his or her default bet. The player will be allowed to change this bet amount before each round and the credits will automatically be updated as hands are played and won or lost. At the bottom of the online blackjack javascript the rules are printed.

Like the additional playing areas these are in a DIV tag with display: One of the form buttons calls a function that will toggle this setting, allowing the player to view the text at will. The cards themselves are created using two user-defined Online blackjack javascript objects, Card and Stack, which represent individual cards and sets decks of cards respectively.

The Card object also provides a means to dynamically display any given card on the page. As these objects are described in previously featured articles on the site, the details won't be discussed again here. You can view the articles at right for some background information if you haven't already read them. Suffice to say, these objects will allow us online blackjack javascript create a deck of cards, shuffle it, deal cards from it and create DOM nodes for displaying individual cards on the page.

The deck or shoe is initially created by a call to the newDeck function which creates a new Stack object, fills it with cards and gives it a good shuffle. It also randomly selects a number to signify a "burn" card near the bottom of the deck.

Before any new round is started, the number of cards left in the deck is checked real money bingo android this value. If the burn card has been reached or passed, a brand new deck is created by calling this function again. This is done to help prevent running out of cards during play. But it's still a possibility especially if the player splits or even resplits so whenever a card needs to be dealt, the getNextCard function is used rather than calling the Stack object's deal method directly.

If first checks whether the deck is empty online blackjack javascript if so, creates a new one. It then uses deal to eurogrand roulette erfahrung online blackjack javascript next card in the deck and return it.

Blackjack Play the game or view the source code. Additional Online blackjack javascript Areas Online blackjack javascript the game is designed for a single player, it does allow "splits. Style Note Setting display: In the interest of reducing file size, the code for the Card and Stack objects has been stripped down in this script to include only the features needed for the game.
