With its roots in a game called twenty-one that is thought to have originated in the early 17th century, blackjack is the world’s most popular casino card games and is offered by countless premier land, online and mobile casinos.
A big part of blackjack’s appeal is it’s so easy to play, because the aim of the game is to beat the dealer and/or get 21 or as close to 21 as possible. While blackjack is available in a host of variants, the aim of the game is always the same.
blackjack types include Classic Blackjack, Perfect Pairs Blackjack Progressive Blackjack, European Blackjack, Double Attack Blackjack, Atlantic City Blackjack, Vegas Strip Blackjack, Blackjack Switch and Double Exposure Blackjack.
On this page we’ll take you through the ins and outs of blackjack from its basics and rules to its card values and payouts and everything in between. We’ll also introduce you to the world’s premier online and mobile blackjack casinos.
Blackjack Basics and the Aim of the Game
Blackjack is a gambling or betting card game played with one or more 52-card decks, with the aim of beating the dealer, preferably by making a natural 21 (a blackjack) or getting as near to 21 as possible without busting (scoring over 21 points).
The point values in blackjack correspond with the card face values, except for picture cards and Aces - Jacks, Queens and Kings count for 10 points each while Aces count for 1 or 11 points each, which makes them the best cards you can be dealt.
A ‘soft hand’ relates to any hand that contains an Ace where the next dealt card - no matter its value - cannot put your total card count over 21. A ‘hard hand’ relates to a hand which has the potential to be ‘bust’ by the very next card dealt.
At the start of each hand you must place a bet which can fluctuate depending on the respective blackjack table limit. Once you’ve placed your bet (on one or more hands if you’re playing at a multi-hand table) the dealer will deal the cards.
They’ll deal you two cards face up so everyone can see them and themselves two cards, one face up and the other face down (a hole card). Depending on your two cards and the dealer’s up card, there are many actions you can take.
For instance, if you get an Ace and a picture or a 10 card, you’ve made a natural blackjack and will be paid out - unless the dealer also has a blackjack. In that case, the hand is considered a Push (a tie), and the dealer will refund your bet.
If you show a pair, you can choose to either Split them to make two separate hands or play them as a single hand with a combined value. If you split them, however, you must double your initial bet and then play each hand independently.
If you haven’t made 21 with any of your hands (and have exercised your option to split or not split your initial cards), you can either Stand (do nothing), Hit (ask to be dealt one or more cards until you reach 21, get close to 21 or you bust).
You can also Double (double your bet for just one more card) or Surrender (give up your hand and retain half of your initial bet). If the dealer is showing an Ace, you can take out Insurance (at a cost of half your initial bet) against them making a natural blackjack.
Once you and the other players have had their turn, it’s time for the dealer to reveal their hole card. If they show a total of 16 or less (or even a soft 17 in some casinos), as per the rules of blackjack, they must deal themselves another card.
If they bust, any player still in the hand (who didn't bust already) will get paid. If the dealer doesn’t bust, it all comes down to the points. Players with more points than the dealer (closest to 21) win and get paid, and players with less lose.
Blackjack Bets and Payouts
There are three main pay-outs in blackjack, 3 to 2 for a natural blackjack, 1 to 1 for any other winning hand, and 2 to 1 for insurance. For instance, if you bet £10 and make a natural blackjack, you’ll win £15 (3 to 2) plus your original £10.
If the dealer also makes a natural blackjack, however, the hand will result in a push, and you’ll only get your original £10 back. For every other winning hand, you’ll win £10 (1 to 1) plus your original £10.
If you take out insurance for £5 (which is always half your initial bet) and the dealer makes a natural blackjack, you’ll be paid out £10 (2 x £5) but you’ll lose your original bet (unless you also make a natural blackjack).
There is another pay-out which is controversial because it favours the casino. Where most casinos – land and online – pay 3 to 2 for a natural blackjack, some only pay 6 to 5 (£12) which, on a £10 bet, is less than 3 to 2 (£15).
As such, we advise you to always seek out blackjack casinos that pay 3 to 2 so you can maximise your winnings. The good news is that you’ll find most if not all of the blackjack mobile and online casinos featured on this site pay 3 to 2.
Most land and online blackjack tables are printed with their respective pay-outs for easy reference.
You’ll discover that payouts fluctuate depending on the type of blackjack variant and its table limits. For instance, in the case of Blackjack Double Exposure, because you get to see both of the dealer’s cards, a natural blackjack only pays 1 to 1 as do all the other winning hands, and the dealer wins all ties except a tied blackjack.
Blackjack Table Limits
Every blackjack game has specified table limits, i.e. the minimum and maximum amounts you can bet per hand. Variants with the word Low in them are for players with smaller budgets, while those with High are for players with bigger budgets.
Low limit blackjack games typically range from £1 to £50, regular or classic blackjack games range from £10 to £500 and high limit blackjack games range from £100 to £5,000. Note that blackjack table limits tend to fluctuate from casino to casino.
Here is a comparison of five common blackjack games offered by five leading UK online casinos so you can see how their respective table limits compare:
Mansion Casino | CasinoPlex | InterCasino | Hello Casino | Casino.com | |
---|---|---|---|---|---|
Blackjack Classic | Min: 0.50Max: 50 | Min: 1Max: 300 | Min: 1Max: 100 | Min: 10Max: 500 | Min: 0.50Max: 50 |

Pontoon | Min: 0.50Max: 50 | Min: 1Max: 300 | N/A | Min: 10Max: 500 | Min: 0.50Max: 50 |
It goes without saying that you should only play online blackjack games with table limits that match your budget. That way you can look forward to lengthy, fun and hopefully worthwhile blackjack sessions.
Blackjack Card Values
In blackjack, every card up to and including 10 is worth its face value, picture cards are worth 10 points each, and Aces are worth either 1 or 11. Cards suits (diamonds, clubs, hearts and spades) play no part in blackjack.
The Aces ‘duel value’ comes in handy because it gives you flexibility when playing your hand. For instance, if you’re dealt an Ace and any card worth 10, you’ll make a natural blackjack (11 points + 10 points = 21 points).
If, however, you’re sitting on 11 points and you’re dealt an Ace, it will count as 1 to give you 12 (if it counted as 11, it would bust your hand), at which point you would ask for another card to hopefully make 21 or close.
This is known as a ‘soft hand’, where at least one of two dealt cards is an Ace. Having a soft hand means it can’t be busted by the next dealt card - regardless of what it is – only improved. Here are some examples of soft hands:
- A 2 = Soft 13 (or 3)
- A 3 = Soft 14 (or 4)
- A 4 = Soft 15 (or 5)
- A 5 = Soft 16 (or 6)
- A 6 = Soft 17 (or 7)
A hard hand, meanwhile, is any two card hand that doesn’t include an Ace, and can be busted with the next dealt card. Here are some examples of hard hands:
- 10 2 = Hard 12
- 9 4 = Hard 13
- 7 7 = Hard 14
- 8 7 = Hard 15
- 10 6 = Hard 16
Blackjack Player Actions
Although you will encounter blackjack variants with slightly different rules, for the most part the following the player actions can be applied to all blackjack variants. Remember that the aim of blackjack is to beat the dealer through them busting, or by you making 21 or as close to 21 without busting yourself.
Bet
Before the start of a hand, place your bet (in chips) to the demarcated area. Single play blackjack lets you play only one hand, while multi-hand blackjack lets you play up to five hands simultaneously. Every hand you play requires a separate bet.
Deal
Once you’ve placed your bet or bets, click the ‘Deal’ button and the dealer will deal two cards face up in front of each set of chips you placed. The dealer will also deal himself two cards, one face up and one face down.

Hope for a Blackjack!
If you don’t have a blackjack, play continues starting with your hand or player to the left of the dealer. Typically, you’ll be given three choices – to hit, stand or double.
Hit
If your card count is low and you want to chase 21, click the Hit button and the dealer will deal you another card. You can hit as many times as it takes to get you to a total you’re happy with, but hopefully without busting (going over 21).

Stand
If you’re happy with your card count and don’t want any more cards, click the Stand button which effectively finalizes your hand.

Double
If you’re initial two cards add up to 10 or 11 and you feel confident you’ll be dealt a 10 value card to get you to 21 or close, click the Double button. This automatically doubles your bet and you’ll be dealt one more card. If you beat the dealer, your winnings are doubled.

Split
When you’re dealt a pair in blackjack, you have the option to split them. By clicking the Split button, each split card becomes a separate hand and will be dealt another card. Every time you split your initial bet will be automatically doubled.
The general rule of thumb in blackjack is to split Aces and 8s, but never 4s, 5s or 10s. In rare cases casinos will give you the option to re-split already split cards, but beware of this because every time you split your total bet size increases.

Insurance
This only comes into effect if the dealer’s face up card is an Ace, which means they have a shot of making a natural blackjack. If you think the dealer’s hole (face-down) card has a value of 10, you can take out insurance for half your initial bet size, which pays 2 to 1. So if the dealer makes a blackjack, you’ll get your original bet back.

Surrender
Although not all blackjack variants offer the surrender option, this is where if you are unhappy with your initially dealt cards, you can choose to give them up and in so doing forfeit half your initial bet, no matter how good or bad the dealer’s hand.

Blackjack Dealer Rules
Now that you know the actions available to you in blackjack as a player, it’s equally important to know what rules of play apply to the dealer.
Unlike you, who can make many choices in each hand, the dealer has to follow a set of pre-determined rules, which in most land and casinos are either:
Term | Definition |
---|---|
Dealer hits on 17 or higher | The dealer must keep hitting on hands that have a total value of less than 17 until they reach a point value of 17, 18, 19, 20, 21 or they bust. Here, a dealer’s Ace is only ever counted as 11. |
Dealer hits on soft 17 | The dealer must hit if they get a soft 17 (which is a hand containing an Ace that counts for 11 or 1), as well as stand on a hard 17 (a 17 point hand that doesn’t have an Ace) and a soft 18 or higher. |
Knowing the rules a blackjack dealer has to follow can give you a slight advantage over the house, and thus help you increase your chances of winning.
