Blackjack 21 Rules

The basic rules of blackjack 21 are simple and easy to understand. In order to play, each player is dealt two cards, one face up and one face down. The dealer is also dealt two cards, one face up and one face down. The cards are then evaluated and a winner is determined.

Objective of the Game

The objective of the game is to get a score of 21 points or as close to 21 points as possible without going over. If a player exceeds 21 points, they automatically lose the hand. The highest possible score is 21 points and is known as a ‘blackjack’.

Card Values

The values of the cards are as follows: Aces are worth either 1 or 11, face cards (Kings, Queens, and Jacks) are worth 10 points, and all other cards are worth their face value.


Before the game begins, each player must place a bet. This bet is the amount of money they are willing to wager on the hand. The minimum and maximum bet amounts are determined by the house.

Playing the Game

Once the bets have been placed, the dealer will deal two cards to each player and two cards to themselves, one face up and one face down. Players will then have the option to ‘hit’, or take another card, or ‘stand’, or keep the hand they have. Players can continue to hit until they reach 21 points or ‘bust’, which means they have gone over 21 points.

Options for Players

Players have several options once the initial cards have been dealt. These options are:

  • Hit – take one more card from the dealer.
  • Stand – keep the cards and take no more.
  • Double Down – double the bet and take one more card.
  • Split – split the hand into two separate hands if the first two cards are of the same value.
  • Surrender – forfeit half of the bet and end the hand.

Determining the Winner

Once all of the players have had a chance to hit, stand, double down, split, or surrender, the dealer will then reveal their face down card. The dealer will then hit or stand based on a set of predetermined rules. If the dealer’s total is higher than the player’s total, the dealer wins. If the player’s total is higher than the dealer’s total, the player wins. If both the player and the dealer have the same total, the hand is a tie and no one wins.


When the dealer reveals their face down card, the players’ bets are paid out based on the outcome of the hand. If the player wins the hand, they will be paid out 1:1. If the player has a ‘blackjack’, they will be paid out 3:2. If the dealer has a ‘blackjack’, the player will lose their bet. If the hand is a tie, the player will get their bet back.

Side Bets

In most casinos, there are also side bets available. These side bets offer the player the chance to win additional money based on the outcome of the hand. Common side bets include ‘Insurance’ and ‘Perfect Pairs’.

Strategy and Tips for Blackjack 21

Blackjack 21 is a game of strategy and luck. There are a few strategies and tips that can help players increase their chances of winning.

Basic Strategy

One of the most important strategies is to follow the basic strategy. The basic strategy is a set of guidelines that tells players the best action to take in any given situation. By following this strategy, players can reduce the house edge and increase their chances of winning.

Card Counting

Card counting is a strategy used by some players to gain an advantage over the house. It involves keeping track of the cards that have been dealt, and then using this information to determine which cards are likely to be dealt next. This strategy is not allowed in most casinos, so players should be aware of the rules and regulations before attempting to use it.

Manage Your Bankroll

Managing your bankroll is an important part of any casino game. Players should always set a limit for how much they are willing to spend, and stick to it. This will help them stay in control and avoid making costly mistakes.
