Blackjack is a game in which players compete against the dealer. The objective of the game is to have a hand with a value closer to 21 than that of the dealer’s, without going over. The card values are the number written on the card, the face of a card (Jack, Queen, King, or Ancestor) and an Ace which counts as either 1 or 11.
Each player is dealt two cards. They can choose to ask for more cards from the dealer, or they can stand (stop drawing) based on a set of rules. The dealer also gets two cards. The dealer must hit on a soft 17 (where one of the cards is an ace) and must stand on a hard 17. If the dealer has a blackjack, all the players’ main bets are collected (unless they also have a blackjack).
In some casinos, the player can choose to take insurance. This side bet is placed on a special portion of the table usually marked “Insurance Pays 2 to 1.” If the dealer has a blackjack, the player loses only their original bet and keeps the insurance money. However, the house still turns a profit from the insurance bets because they are essentially paying players to not play their hands.
There are many variations of the game. For example, some tables remove the tens from the decks. This decreases the value of aces and the overall power of the players’ hands. In most cases this change will not affect the basic strategy of the game.
Another variation is the use of multiple action, a rule that allows players to place two or more bets on a single hand. This increases the amount of hands a dealer can deal per hour, and it also affects the pay-out structure. In this case, a blackjack pays out at 1:1 instead of the usual 3:2.
The game is often played with six or eight decks. It is also common to find games that have a fixed minimum bet, or a maximum bet for each hand. This limits the maximum amount a player can win, and prevents the dealer from gaining an advantage.
Whether you are playing with one or multiple decks, there are strategies that can help you beat the dealer and improve your chances of winning.
