Blackjack is rules American version of a popular global banking game known as Twenty-Onewhose relatives include Pontoon and Vingt-et-Un. Players git not compete against each other. It is played hit one or more decks of 52 cards, and is the yit widely played casino banking game blackjack the world. Players are each dealt two cards, face up or down depending on the casino and the table at which they sit. In the U. In most other countries, the dealer receives one card face up.
In most non-U. With no hole card, it is almost never correct basic strategy to double or split against a dealer ten or ace, since a dealer blackjack will result in the loss of the split and double bets; the only exception is with a pair of aces against a dealer 10, where it is still correct to split. In all other cases, a stand, hit or surrender is called for.
For instance, holding 11 against a dealer 10, the correct strategy is to double in a hole card game where the player knows the dealer's second card is not an acebut to hit in a no hole card game. The no hole card rule adds approximately 0. The "original bets rules rule variation appearing in certain no hole card games states that if the player's hand loses to a dealer blackjack, only the mandatory initial bet "original" is forfeited, and all optional bets, meaning doubles and splits, are pushed.
Each blackjack game has a basic strategywhich prescribes the optimal method of playing any hand against any dealer up-card so that the long-term house advantage the expected loss of the player is rules. An example of a basic strategy is shown in the table below, which applies to a game with the following specifications: .
The bulk of basic strategy is common to all blackjack games, with most rule variations calling for changes in only a few situations. For example, to use the table above on a game with the stand on soft 17 rule which favors the player, and is typically found hit at higher-limit tables today only 6 cells would need to be changed: hit on 11 vs.
A, hit on 15 vs. A, stand on 17 vs. A, stand on A,7 vs. Regardless of the specific rule variations, taking insurance or "even money" is never the correct play under basic strategy. Estimates of the house edge for blackjack games hit by casinos and gaming regulators are generally based on the assumption that the players follow basic strategy and do not systematically change their bet size.
Most blackjack games have a house edge of between 0. Casino promotions such as complimentary match play vouchers or blackjack payouts allow the player to acquire an advantage without deviating from basic strategy. Basic strategy is based upon a player's point total and the dealer's visible card.
Players may be able to improve on this decision by considering the precise composition of hit hand, not just the point total. For example, players should ordinarily stand rules holding 12 against a dealer 4. However, in a single deck game, players should hit if their 12 consists of a 10 and a 2. The presence of a 10 in the player's hand has two blackjack . However, even when basic and composition-dependent strategy lead to different actions, the difference in expected reward is small, and it becomes even smaller with more decks.
Using a composition-dependent strategy rather than basic strategy in a single deck game reduces the house edge by 4 in 10, which falls to 3 infor a six-deck game. Blackjack has been a high-profile target for advantage players since the s. Advantage play is the attempt to win more using skills such as memory, computation, and observation. These techniques, while generally legal, can be powerful enough to give the player a long-term edge in the game, making them an undesirable customer for the casino and potentially leading to ejection rules blacklisting if they are detected.
The main techniques of advantage play in blackjack are as follows:. During the course of a blackjack shoe, the dealer exposes the dealt cards. Careful accounting of the exposed cards allows a player to make inferences about the cards which remain to be dealt.
These inferences can be used in the following ways:. A card counting system assigns a point score to each rank of card e. When a blackjack is exposed, a counter adds the score of that card to a running total, the 'count'. A card counter uses this count to make betting and playing decisions according to a table which they have learned. The count starts at 0 for a freshly shuffled deck for "balanced" counting systems. Unbalanced counts are often started at a value which depends on the number of decks used in the game.
Blackjack's house edge is usually between 0. Card counting is most rewarding near the blackjack of a complete shoe when as few as possible cards remain. Single-deck games are therefore particularly advantageous to the card counting player. As a result, casinos are more likely to insist that players do not reveal their cards to one another in single-deck games. In games with more decks of cards, casinos limit penetration by ending the shoe and reshuffling when one or more decks remain undealt.
Casinos also sometimes use a shuffling machine to reintroduce the exhausted cards every time a deck has been played. Card counting is legal and is not considered cheating as long as the counter is not using an external device,  : but if a casino realizes a player is counting, the casino might inform them that they are no longer welcome to play blackjack.
Sometimes a casino might ban a card counter from the property. The use of external devices to help counting cards is rules in all US states that license blackjack card games. Techniques other than card counting can swing the advantage of casino blackjack toward the player. All such techniques are based on the value of the cards to the player and the casino as originally conceived by Edward O.
Shuffle tracking requires excellent eyesight and powers of visual estimation but is more blackjack to detect since the player's actions are largely unrelated to the composition of the cards in the shoe.
Arnold Snyder's articles in Blackjack Hit magazine brought hit tracking to the general public. His book, The Shuffle Tracker's Cookbook, mathematically analyzed the player edge available from shuffle tracking based on the actual size of the tracked slug. Jerry L. Patterson also developed and published a shuffle-tracking method for tracking favorable clumps of cards and cutting them into play and tracking unfavorable clumps of cards and cutting them out of play.
The player can also gain an advantage by identifying cards from distinctive wear markings on their backs, or by hole carding observing during the dealing process the front of a card dealt face down. These methods blackjack generally legal although their status in particular jurisdictions may vary. Many blackjack tables offer a side bet on various outcomes including: .
The side wager is typically placed in a designated area next to the box for the main wager. A player wishing to wager on a side bet is usually required to place a wager on blackjack.
Some games require that the blackjack wager should equal or exceed any side bet wager.
Blackjack - Wikipedia
A non-controlling player of a blackjack hand is usually permitted to place a side bet regardless of whether the controlling player does so. The house edge for side bets is generally far higher than for the blackjack game itself. Nonetheless side bets can be susceptible to card counting.
A side count, designed specifically for a particular side bet, can improve the player edge. Only a few side bets, like "Lucky Ladies", offer a sufficient win rate to justify the effort of advantage hit. In team play it is common for team members to be dedicated toward counting only a sidebet using a specialized count.
Blackjack can rules played in tournament form. Players start with an equal numbers of chips; the goal is to finish among the top chip-holders.
Depending on the number of competitors, tournaments may be held over several rounds, with one or two players qualifying from each table after a set number of deals to meet the qualifiers from blackjack other tables in the next round. Another tournament format, Elimination Blackjackdrops the lowest-stacked player from the table at rules points in the tournament. Good strategy for blackjack tournaments can differ from non-tournament strategy because of the added dimension of choosing the amount to be blackjack. As in poker tournaments, players pay the casino an initial entry fee to participate in a tournament, and hit are sometimes permitted.
Some casinos, as well as general betting outlets, provide blackjack among a selection of casino-style games at electronic consoles. Video blackjack game rules are generally more favorable to the house; e. Video and online blackjack games generally deal each round from a fresh shoe, rendering card counting ineffective in most situations.
