How to play blackjack online

To play blackjack online, you need a solid understanding of the rules and strategies. In the comfort of your own home, you can challenge the virtual dealer and test your skills in online blackjack.

Basic Blackjack Rules

The rules state that your objective is to obtain a hand whose total value is as close as possible to 21 without exceeding it. Each card has a specific value: face cards are worth 10, aces can be worth 1 or 11 depending on what is convenient for the player, and the other cards maintain their nominal value. At the beginning of the game, two cards are dealt to both the player and the dealer, starting the competition against the house.

Key terms in blackjack

In blackjack, it is essential to know and understand a series of terms:

  • 'Hit': take another card to increase the total value of your hand;
  • 'Stand': stop taking cards, keeping the current total value of your hand;
  • 'Bust': situation where the total value of your hand exceeds 21 points;
  • 'Push': occurs when both the player and the dealer have hands with the same total value;
  • 'Blackjack': having an Ace and a 10-value card in the first two cards, totaling 21;
  • 'Split': if your first two cards are of the same value, you can split them into two separate hands;
  • 'Double Down': doubling your initial bet and receiving only one additional card;
  • 'Insurance': a side bet that can be made when the dealer shows an Ace;
  • 'Surrender': option to withdraw from the hand and get back half of the bet;
  • 'Soft Hand': a hand that contains an Ace that can be counted as 1 or 11 without busting;

blackjack strategy

Strategy is crucial for success in blackjack. It's about making informed decisions that optimize your chances of winning.

Basic blackjack strategy:

The basic strategy of blackjack is the statistically optimal way to play each hand. It defines when to hit, stand, split, and double down. It is used through strategy charts, developed with precise calculations.

Blackjack card counting:

Card counting in blackjack is a tactic to anticipate the cards that will come. Although it is legal, casinos have the right to deny service to card counters. There are famous figures in this practice, with fascinating stories.

Advanced Blackjack Strategies:

In addition to basic strategy and card counting, there are advanced strategies in blackjack, such as deck tracking and ace sequencing. Although effective and legal, they require skill and experience. Some notable players like Ken Uston have mastered these techniques.

House edge and RTP in blackjack

In blackjack, the house edge represents the casino's mathematical advantage, while the RTP (Return To Player) is the theoretical long-term money return to the player. Both concepts are key to understanding the game's probabilities.

House edge explained

The house advantage in blackjack is the percentage of each bet that the casino expects to retain in the long term. Factors such as more decks in play, the dealer hitting on soft 17, and restrictions on doubling down or splitting increase this advantage.

However, the player's blackjacks that pay 3:2, the option to double the bet after splitting, and the dealer standing on soft 17 decrease the house edge.

RTP Explanation

The RTP (Return To Player) in blackjack is the percentage of the total amount of money wagered that is expected to be returned to the player in the long term. With optimal strategy, the RTP can exceed 99%, making it one of the best casino games for players. However, the specific rules of a blackjack variant can affect this percentage.

Effect of Strategy on House Edge and RTP

The low house edge and high RTP in blackjack assume optimal play. Deviations or errors in basic strategy can increase the house edge and decrease the RTP, affecting your chances of success.

Impact of Variations on House Edge and RTP

The different variants of blackjack have different house advantages and RTPs due to changes in regulations. For example, variants like Blackjack Switch or Atlantic City Blackjack have different probabilities that can affect your results.

House edge and RTP in reality

It is crucial to remember that the house edge and RTP in blackjack are long-term averages that may not reflect short-term results. In any individual session, luck and variation play a significant role.

Diferentes variaciones de blackjack

Different Blackjack Variations

The world of blackjack is vast and varied. Beyond classic blackjack, there are versions such as European Blackjack, American Blackjack, and the exclusive Indian 21.

Other popular variations include Single Deck Blackjack, Pirate 21, Super 7 Blackjack, Blackjack Switch, Double Exposure Blackjack, Mini Blackjack, and Blackjack VIP. Each one, like blackjack 21, offers unique rules and challenges, enriching the gaming experience.

Key Differences in Blackjack Variations

Blackjack is not a monolithic game; its multiple variations present different instructions and strategies. Below, we will see the key differences between the most popular versions of the game.

European Blackjack

  • The dealer only takes their second card after all the players have completed their hands.

American Blackjack

  • The dealer takes their second card (hole card) before the players have finished their hands.
  • The dealer can check for blackjack immediately if their face-up card is an Ace or a ten-value card.

Single Deck Blackjack

  • It is played with a single deck of 52 cards;
  • It can slightly decrease the house edge compared to multiple deck games.

Double Exposure Blackjack

  • Both dealer's cards are exposed, providing more information to the player.
  • Blackjacks only pay even money.
  • The dealer wins in all ties, except in a natural blackjack.
  • The player can only split once and double the bet only on hard totals of 9, 10, or 11.

Indian 21

  • It is played with a Indian deck of 48 cards (without 10s).
  • The player's 21 always beats the dealer's 21, even a blackjack.
  • Players can double the bet with any number of cards.
  • Late surrender is allowed, offering the opportunity to recover half of the bet.
  • Bonus payments for certain combinations of 21.


  • Similar to Indian 21, all 10s are removed and both of the dealer's cards are dealt face down.
  • Players can 'request' (hit) after doubling the bet;
  • Extra payments for a 'pontoon' (an ace and a ten-point card) and a 'five-card trick' (five cards that add up to 21 or less).

Super 7 Blackjack

  • Side bet on the first card, or the first two or three cards, being 7s.
  • The payout increases if the 7s are of the same suit or if the player gets three 7s.

Blackjack Switch

  • Players are dealt two hands instead of one and can exchange the second card dealt to each hand.
  • On the 22nd, the dealer pushes against any player total of 21 or less, but a player's blackjack still wins.
  • Rule variations often include only paying equal money on a player's blackjack.

Perfect Pairs Blackjack

  • It offers a side bet on the player's first two cards forming a pair.
  • Payments vary depending on whether the pair is mixed (different suits), color (same color, different suits), or perfect (same suit).

Blackjack Surrender

  • Allows players to 'surrender' and lose half of their bet if they believe their hand will lose against the dealer;
  • This option is usually available only after the first two cards are dealt and before any other actions are taken.

mini blackjack

  • A simplified version designed for mobile devices or smaller browser windows;
  • Typically the same rules as the standard.

VIP Blackjack

  • Targeted at high rollers with higher minimum and maximum bets;
  • Typically the same rules as the standard.

blackjack history

Blackjack, as we know it today, has roots that date back to the 17th century, being popular in French casinos under the name 'Vingt-et-Un'.

Over the years, this game has evolved, adopting its current name and criteria, establishing itself as one of the favorites in casinos around the world.


We have seen that blackjack is a game of strategy and skill where basic strategy is essential and card counting is an advanced tactic. There are noticeable differences between playing online and in a physical casino, such as convenience versus atmosphere.

With variants like European, American, and Indian 21, there are options for all tastes. Prominent casinos like Vulkan Vegas, LEGZO, Strendus, 10bet, and Spin Casino offer games with unique experiences, while playing live through the web provides an added authenticity.
