21 blackjack is a popular casino game that is played with a deck of 52 cards. The goal of the game is to score as many points as possible by playing cards that add up to 21.
To begin the game, each player is dealt two cards face down. These two cards, plus the player’s original card, are used to form the player’s hand.
A player may only play cards that add up to 21. For example, if a player has a 10 and an 8 in their hand, they may not play a 3 or a 6.
If a player has two cards that add up to 21 (10 and an 11), they may play either card.
To make a decision about how to play, a player counts up their points in their head. If the total point value of their hand is equal to or greater than the value of the current blackjack table minimum (usually 10 or 20), then the player can play that hand according to normal rules.
If not, the player must subtract 1 point from their score for every card they are missing (i.e., if they have 9 points in their hand and the table minimum is 18, they would subtract 1 point from their score so that their final total would be 17).
If at any time a player has no remaining points, they lose the game and are awarded nothing (other than whatever money they may have already lost).
The goal of 21 blackjack is to make as many hands as possible where the point value of all of the players’ hands combined equals or exceeds the table minimum. In order to win at 21 blackjack, it is important to understand how different hands score and what strategy is best for achieving this goal.
