Online blackjack remains one of the most widely recognised casino card games, both in an online format and in physical table form. Reasons range from its comparatively high RTP, the role of decision-making during hands and its simple but strategy-centric gameplay. Players also commonly cite the role of skill in shaping outcomes as a reason for preferring blackjack to other casino card games, although skill affects variance rather than guaranteeing better results.
Simpler Rules and a Variety of Decisions
A relatively simple objective and scoring system is used in blackjack, especially when compared with many other casino card games. The idea is to create a hand with a value closer to 21 than the dealer’s, without exceeding 21 and going bust.
An easy-to-understand scoring system is also used:
- Number cards keep their face value
- Picture cards count as 10
- Aces hold a value of 1 or 11
The player acts before the dealer completes their hand, and the two totals are then compared. A natural blackjack, 21 with two cards, beats all other hands, even 21 hands created using more cards. This hand is possible only with the first two cards dealt to a position and consists of a picture card and an ace. In the event the dealer and player both have a natural blackjack, it is a Push (tie), with the bet returned to the player.
As the hand plays out, participants can make decisions based on their hand. Options include:
- Stand: Drawing no additional cards
- Hit: Receiving an extra card
- Split: Splitting a paired hand into two separate hands
- Double Down: Place an extra stake following the first two cards in return for just one additional card
- Surrender: Dropping out of the hand after the first two cards in return for half the stake back
That additional decision-making element distinguishes blackjack from many passive casino games in which player choices have little or no impact on how a round is played.
A Simple Head-to-Head Structure
While multiple people, usually up to eight, can sit at a blackjack table and take part in the same round, they’re not competing with each other. Each player is going head-to-head with the dealer, and their results are independent of everyone else’s. Some could win, some could lose, and in other instances, a push can occur when the hand ends in a tie.
It is a format that translates well to both virtual blackjack games powered by random number generators and live dealer variations featuring a human dealer streamed via a webcam, so results are delivered in real time using real cards and shoes.
Strategy is an Element of the Game
Blackjack differs from most casino games in its strategic elements, as in-game decisions can impact a player’s success over a long session. Mathematicians studied the game’s mathematics for years to invent a ‘basic strategy’. It takes every possible player’s total versus the dealer’s upcard and then mathematically tells a player whether a ‘hit’, ‘stand’, ‘split’, ‘double down’, or in some cases ‘surrender’ gives the player the highest percentage of winning.
By following the correct ‘basic strategy’ according to the rules of the table, a player can play what is known as a ‘perfect game’. Conversely, players who do not follow basic strategy do not maximise their wins or minimise their losses and end up losing to the low RTP/house edge that has made Blackjack one of the most popular casino games today.
Some of the Highest RTPs
Another reason for Blackjack’s popularity is its comparatively high RTP compared to most other casino games. The RTP is basically the expected return to player ratio over thousands of hands. For example, with a 99% RTP, a player can expect to lose 1% over time.
RTP can vary from one blackjack game to another. That’s because, over the years, the games have evolved, and there are multiple rules that any table can use. Some may come with an RTP of 99.5%, which is about the average for blackjack.
The opposite of RTP is the house edge, which represents the expected return to the dealer over thousands of hands. Therefore, a 99.5% RTP gives the house a 0.5% edge. The key principles for players are that blackjack games with a high RTP or low house edge reduce the player’s chances of losing and the house’s chances of winning.
Live Blackjack & Multiple Game Variations
The game of blackjack is usually found in two different formats at online gambling sites. The first is a virtual variation that delivers results using a random number generator, and the second is a live table stream from custom studios or land-based casinos. The latter features human dealers and is played out in a similar physical way to games hosted in brick-and-mortar venues.
Depending on the blackjack game played, rules can also differ. For example, some games require the dealer to hit on a soft 17 (H17), while others require the dealer to stand (S17). Players may also face different rules regarding surrender, split pairs, or double-down actions.
Why Blackjack Keeps Its Position
Blackjack is widely regarded among the most popular card games in online casino lobbies. Considering its mix of strategy-based gameplay, variety of table variations and lower-than-average house edge, not many would see that changing in the near future.
Still, as with all casino games, the odds favour the house, meaning most players will lose over the long term. While player decisions can influence expected returns under a given ruleset, they do not eliminate the risk of gambling or guarantee positive results.
