Blackjack is one of the most popular online casino games, and it’s easy to see why. This card game is a thrilling mix of strategy and luck and offers some of the lowest house edges of all casino games. With plenty of variations on offer, including live dealer tables, there’s plenty of fun to be had. This is why we’ve picked out the very best online blackjack sites, so that you can easily compare and pick out your favourite. Want to find out more about this much-loved casino classic? Read on for everything you need to know about playing blackjack online.

The aim of the game is to hit 21 or get as close as you can without going bust, which means going over 21. In blackjack, number cards are their face value, face cards are worth 10, while Aces are worth 1 or 11, depending on which suits your hand. The exact rules vary depending on the blackjack variation you’re playing, but most games play out in a similar way. Before we take a look at how a game of blackjack plays out, let’s take a look at the moves available to players:

Hit – You’re dealt another card to add to your hand.

Stand – You keep your hand as it is and don’t receive any more cards.

Split – If your first two cards are the same value, you can choose to split them into two separate hands. You’ll need to add a second bet equal to the first if you split.

Double down – You double your initial bet and receive one more card before standing. In some variations, you can’t double down after splitting.

Surrender – This move is only available in certain games and allows you to surrender the round and only lose half your bet.

Now we’ve got to grips with the blackjack moves, let’s take a step-by-step look at how to play blackjack:

  1. The dealer deals two cards to both yourself and the house. Your two cards will be dealt face up, while the dealer will have one face up—-the hole card—-and one face down.
  2. If you or the dealer get a ‘natural’ blackjack on the first draw, then the round ends there. If not, you can choose to hit, stand, double down or split.
  3. If either you or the dealer hit, another card is dealt. The process then repeats until both players stand, one player hits 21, or goes bust. If both players stand, the one with the hand closest to 21 wins the round.

One of the biggest draws of blackjack is that it offers some of the lowest house edges of all casino games. As blackjack is partly skill-based, the house edge is affected by your strategy. This means that, unlike in other games like slots and roulette, making the right moves can give you a better chance of winning. The house edge for a standard blackjack game when playing with basic strategy is around 0.42%. The house edge differs depending on the blackjack variation you’re playing and whether you’re wagering on side bets.

You can check the return to player (RTP) of online blackjack games by clicking on the ‘i’ or ‘help’ button once you load up a game. The house edge is the opposite of the RTP – so if the RTP is 9.58%, the house edge is 0.42%.

Strategy

Improve your chances with blackjack strategy

If you want the best chance of winning at blackjack, you’ll need to use optimal strategy. This involves knowing what move to make depending on the strength of your hand. While blackjack strategy can’t guarantee you a win, seeing as you have no control over what cards are drawn, it can lower the house edge.

Some basic blackjack strategy tips are well known and easy to remember, such as always hit on a hard 11 or always stand on a hard 17. It’s not easy to learn the right move for every scenario by heart, but there are many blackjack strategy charts available online which tell you the best move to make. Luckily, you can play online blackjack while having your strategy chart at hand until you get the hang of things.

In classic blackjack, the payout for blackjack is 3:2, or 1.5 times your bet amount. If your hand is closer to 21 than the dealers or the dealer goes bust, you’ll receive a 1:1 payout. In most variations, if the round ends in a tie and both the player and the dealer’s hands total 17, 18, 19, 20 or 21, ?

Lots of blackjack variations offer different payout rates. For example, many variations that have additional rules that benefit the player, like seeing both the dealer’s first cards, make up for this advantage by offering lower payout rates. Similarly, some games have rules that make it harder for the player but make up for this with increased payouts.

Variations

Try out different blackjack variations

There are a wide range of exciting game variations available at Ireland’s best blackjack sites. Let’s take a look at the top titles on offer.

Blackjack surrender – This variation allows you to cut your losses if you don’t fancy your first hand by only losing half your bet. While most games don’t allow you to surrender if the dealer gets a natural, a few variations do – this is known as early surrender.

Blackjack switch – In blackjack switch, you’re dealt two hands instead of one. You can choose to switch the second cards of each hand to create the strongest possible hands.

Double exposure – Here, both the dealers cards are face up. This is an advantage for the player, but casinos make up for this by offering slightly lower payouts. In this variation the dealer also wins on ties unless you land a natural.

Pontoon – This is essentially the opposite to double exposure – both the dealer’s cards are face down. This obviously makes things more difficult for the player, but in exchange there’s an increased payout for natural blackjack of 2:1 rather than 3:2.

Multi-hand blackjack – This variation uses the standard blackjack rules but lets you play multiple hands at once. Some games allow you to play up to five hands at a time, meaning five times the fun.

Many online blackjack games have optional side bets that you can wager on as well as wagering on your hand. These bets are separate to the main game and are based purely on luck. Side bets are popular because they offer high payouts if you get lucky. The side bets on offer vary depending on the blackjack game you’re playing, but here are the most popular:

Perfect pairs – This is a bet that your first two cards will be a pair. The payout depends on the strength of the pairing – a ‘perfect’ pair of the same rank and suit usually pays out 25:1, while a red and black pair typically pays 6:1.

23+1 – Here you’re betting that your first two cards and the dealer’s hole card will form a flush, straight, three of a king, straight flush or suited three of a kind. Again, the payouts depend on the strength of the hand.

Insurance – If the dealer’s hole card is an Ace, you can insure your bets against the dealer by placing an insurance bet equal to half the amount of your initial wager. If the dealer does have blackjack your insurance bet pays 2:1, meaning you don’t lose your original bet.

Progressive – Some blackjack games offer a progressive jackpot siddbet. In most progressive blackjack variations, this involves betting on Aces. Depending on the variation, you may need to draw four consecutive Aces of the same suit to land the jackpot.

While side bets offer high payouts, they also increase the house edge due to the slim odds involved. For example, your chances of correctly betting on a perfect pair is only around 1.6%.

Your Questions Answered

Is online blackjack fair?

Yes. All the casinos on our list are licensed. All the animated blackjack games at these sites use random number generator (RNG) technology and are audited to ensure fairness, while the live blackjack games are run by unbias dealers.

What’s the difference between hard and soft hands?

A hard hand is one that includes an Ace, whereas a soft doesn’t. Hard hands are stronger because if the round ends in a tie and you have a hard hand whereas the dealer doesn’t, you’ll win the round.

Most blackjack games use six or eight decks. A few online casino sites offer single deck blackjack, which has a house edge of around just 0.1% when played using optimal strategy, but this game isn’t available at all casinos.

Free blackjack games are perfect if you just want to play for fun, and they’re also ideal if you want to work on your strategy before playing online blackjack for real money.
