What is online blackjack?

Blackjack is one of the most popular casino banking games in the world, with blackjack tables ever-present on gambling sites and physical casinos the world over.

In simple terms, blackjack pits the player against the dealer (rather than against other players), with the player aiming to create card totals that are higher than the dealer but lower than 21.

Card totals are totted up via the numbers on the cards dealt to you – the game uses a standard 52-card deck. The two basic moves a player can make is either to choose to keep having cards drawn (known as a ‘hit’), or to end their turn and stop taking cards (a ‘stand’).

In practice, the game is more complicated than this, with other actions a player can take, and there are plenty of resources and ways to practice that you can make use of online.

There are several different types of blackjack available online. American Blackjack, as it’s known, is the standard type found in most online casinos, with European Blackjack another variation, which is played with two decks of 52 cards.

Other variations available at most casinos include free bet blackjack, in which players don’t have to bet when choosing certain play options, and Spanish 21, in which 10s are removed from the dealers deck (among other things).

The most common ‘variation’ of blackjack online, while not changing any of the rules, is the presence of live dealer games. These are popular with customers, as they allow them to see a real-time person dealing, and often feature a live chat option too.

Tips for playing blackjack online

For beginners looking to play blackjack online successfully, here are a few key tips:

1. Learn the Rules: This may sound basic, but there’s a lot to learn.Understand the basic rules first, including the goal of getting as close to 21 as possible without going over. Know when to hit, stand, double down and split.

2. Use Basic Strategy: Follow a basic blackjack strategy chart, which tells you the optimal move for every hand based on your cards and the dealer’s upcard. This reduces the house edge.

3. Manage Your Bankroll: Set a budget before you start and stick to it. Avoid chasing losses and only wager a small portion of your bankroll per hand.

4. Avoid Insurance Bets: Insurance bets generally aren’t profitable and increase the house edge, so it’s best to avoid them.

5. Play at Low Stakes: Start with low stakes to get comfortable with the game and strategy without risking large amounts.

By sticking to these tips, beginners can maximise their chances of success and enjoy a more strategic, controlled game of online blackjack.
