About Blackjack

Standard Blackjack, or also known under the name of 21 is a traditional card/table game that is played with six standard decks of 52 cards and at specialized Blackjack tables. Some variations, however, may require a different number of decks (1, 4 or 8). It is a game in which the player competes with the dealer to achieve the main goal, which is to get a hand closer to the value of 21 than the dealer’s hand. Going over 21 is known as “busting”.

At the beginning of each hand, both the player and the dealer receive the initial two cards. Usually, the player gets both cards face-up, while the dealer receives one card face down, which is known by the name of “hole card”.

As for the card values, those from 2 up to 10 possess the same value written on the card. Kings, queens and jacks take the value of 10, while Aces can occupy two values. They either count as 1 (hard hand) or as 11 (soft hand), depending on the remaining cards in the hand.

The initial hand in which one gets a card that counts 10 and an ace goes by the name of “Blackjack”. This combination represents the strongest hand in the game, and it can beat all other combinations, excluding the Blackjack hand itself.

Types of Bets

The game comes with two types of wagers - main bets and side bets. Main bets include hit, stand, double down, split pairs, surrender and insurance. Hit allows the player to get an additional card. Stand means that there is no further action in the current hand. In double down the player “hits” one time, while simultaneously doubling his wager. Split cards allow the player to divide the initial two cards and continue creating two separate Blackjack hands, which can be useful when the initial cards possess the same value. Surrender option can be found at a large number of online casinos but there are also the ones that don’t include this type of wager. Insurance is a kind of a side bet in which the player can wager half of his initial stake on the option that the dealer, which face-up card is ace, will score the Blackjack hand.

The list below displays all types of twenty-one side bets:

  • Lucky Lucky - dealer’s face up card and the entire player’s hand combine, to sum up, either 19, or 20 and 21.
  • Perfect Pairs - the initial player’s hand is, in fact, a pair.
  • Royal Match - the initial player’s hand is either suited or connected and suited or a king and a queen.
  • 21+3 - the initial player’s hand and the dealer’s face up card create a poker hand (three of a kind), or straight or flush.
  • Lucky Ladies - the initial hand of the player counts 20.
  • In Bet - dealer’s face up card takes the values between player’s initial cards.
  • Bust It - the first card that the dealer receives will result in a bust.
  • Match the Dealer - either one or both initial cards from the player’s hand take the same values as the face-up card from the hand of the dealer.

The most played and offered side bets at online casinos are “21+3” and “Perfect Pairs”. However, some casinos offer more side betting options.

Tips & Strategies

Given that in the online version of twenty-one the decks are being shuffled after each and every hand, there are no real strategies for playing the game, such as the popular card tracking or card counting. The first thing one needs to do before entering the world of online twenty-one is to get pretty familiar with all the rules, bet types, house edge percentages and such. The rest comes down to knowing when to choose which type of wager, which will slowly come through gaining experience. For starters, it may be better to play several hands for free, before starting playing for real money.

One of the main things is maintaining a steady watchfulness, which is certainly helpful when making a decision which wager to choose next. When the streak is long, tracking the cards that have appeared may come in handy but don’t expect anything extraordinary from that.
