Classic 21 Blackjack Basics

Let's start with the basics first. Classic blackjack has essentially the same basic structure as all other blackjack games. In this context, here are the most important things you need to know before starting your play 21 blackjack online business:

  • The game is played between the dealer and the player.
  • Between 2 and 8 decks are used in each game. There are no Joker cards in these decks.
  • The goal is to score a total of 21 points or beat the dealer by getting as close to that number as possible.
  • The values ​​of cards 2 to 9 are the numbers on them.
  • The 10, Jack, Queen and King cards are worth 10 points. Ace cards are worth 1 or 11 points (whichever is in favor of the player).
  • One of the main differences of Blackjack 21 is the way the cards are dealt. The dealer (or software) deals the cards after bets are placed.
  • The player takes two cards, both face down.
  • The dealer takes a single card and lays it face up on the table. Only after the player has played his hand can he take another card.

How to Play Classic Blackjack 21

After these basics, we can start answering the question of how to play 21 blackjack games. After the cards are dealt, the player has multiple choices and must choose one of them. Depending on the state of the cards on the table, the game may also end automatically. In this regard, possible scenarios are:

  • If the player's first two cards form a "blackjack" (i.e. 10 and Ace), he automatically wins the game.
  • If the dealer has the same cards in his hand, a game mode known as "push" begins.
  • If, at any stage of the game, the total of the cards in the player's or dealer's hand exceeds 21 points, that side is deemed to have lost. This is called a "bust".

These are scenarios that automatically end or win a game of blackjack 21. However, if the total of the cards in the player's hand is less than 21 points, he must make one of the following decisions for the game to continue:

  • Hit: The player requests and takes another new card.
  • Stand: The player is sure of the cards in his hand and does not want another card.
  • Split: If two cards are of the same value (eg 2 – 2), the player splits them into two and plays as two different hands. He can win both hands, lose both, or win one and lose the other.
  • Double Down: The player doubles his bet and takes another card. He must stop after receiving this card.
  • Surrender: Player gives up and loses but gets half of his bet back.

After one of these decisions is made, the dealer takes his second card and plays his own hand. At this stage, the following scenarios may occur:

  • The dealer can explode past 21 points. In this case, the player wins.
  • If the dealer decides to stand, the total points of the player's and dealer's cards are compared. The side with the higher score wins.
  • If both sides have the same score, the push mode mentioned above will be activated and the player will get their bet back.

Rules of Blackjack Classic

Classic blackjack rules, aka 21 blackjack rules, are a little different from other variants. The most important difference is in the way the cards are dealt, as mentioned above. In this context, here are the most important rule differences you should be aware of when playing blackjack 21:

  • If the dealer has blackjack (10 + Aces), the dealer is considered to have won, even if the player has 21 points.
  • However, if both sides have blackjack (10 + Aces), the push mode is activated and the player gets their bet back.
  • If the dealer has 16 points, he has to get a new card.
  • If the dealer has 17 soft points, he must stand. (Hands with Aces are called soft, hands without Aces are called hard.)
  • The player can decide to Split only once per hand.
  • The player cannot split 4's, 5's, or non-identical 10-point cards (for example, 10-J, Q-K, J-K, etc.).

  • The player can only double if he has 9, 10 and 11.
  • The player can double down on split hands.

Strategy Basics: Classic Blackjack Strategy

Strategy Basics: Classic Blackjack Strategy The house edge of 21 blackjack games is around 0.42% when 4 to 8 decks are used. The rule differences we mentioned above require some tweaks to traditional strategies as well, for example, to stop playing aggressively. In general, it would be best to play more defensively and not take unnecessary risks.

This is especially true if the dealer's up card is an Ace or another card worth 10 points. In this scenario, the player has no idea how many points the dealer can reach, as he will only be able to see the second card after he has played it. Therefore, options such as doubling or splitting become riskier, especially considering that the dealer's blackjack will beat the player's 21 points. Therefore, both options should be used very carefully.

These options are also already restricted for the following reasons:

  • It is only possible to double down on 9, 10 and 11 points. If the dealer has 10, you cannot double, even if you have 11 points.
  • As stated in the 21 blackjack rules section, 4s, 5s, and non-identical 10 point cards cannot be split.

21 blackjack card counting is theoretically possible, but will be very difficult in games with more than 2 decks. We recommend not using this technique, especially in 8 deck games: If you don't know what you're doing, this technique can mislead you.

Blackjack strategy charts will be helpful for players who are just starting out playing 21 blackjack: If you are unsure of which decision to make, we recommend that you take a look at these charts.
