Blackjack, also known as twenty-one, is a comparing card game between usually several players and a dealer, where each player in turn competes against the dealer, but players do not play against each other. Let the dealer draw additional blackjack strategy until their hand exceeds 21. 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. Aces can be worth one or eleven. A hand’s value is the sum of the card values. Once all the players have completed their hands, it is the dealer’s turn.
The dealer hand will not be completed if all players have either busted or received Blackjacks. The dealer then reveals the hidden card and must hit until the cards total 17 or more points. At most tables the dealer also hits on a «soft» 17, i. Since the 1960s, blackjack has been a high-profile target of advantage players, particularly card counters, who 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-one, a game of unknown origin.
The first written reference is found in a book by the Spanish author Miguel de Cervantes, most famous for writing Don Quixote. When twenty-one was introduced in the United States, gambling houses offered bonus payouts to stimulate players’ interest. The first scientific and mathematically sound attempt to devise an optimal blackjack playing strategy was revealed in September 1956. 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 52-card decks are shuffled together. At the beginning of each round, up to three players can place their bets in the «betting box» at each position in play. Each box is dealt an initial hand of two cards visible to the people playing on it, and often to any other players. Cards are dealt either from one or two handheld decks, from a dealer’s shoe, or from a shuffling machine.
