Blackjack is one of the most familiar card games in UK casinos, both in person and online. The rules are simple and the pace is steady once you know what to look for.
A little groundwork goes a long way. Understanding card values, the choices available on each hand, and how the dealer acts helps everything click into place.
This guide explains how a round works, what terms like hit, stand, double and split mean, and how insurance, surrender, decks and payouts fit in. If you choose to play, set limits that suit you and keep it casual.
Blackjack is a card game played against a dealer, not other players. Each hand aims to reach a total as close to 21 as possible without going over.
At the beginning of a round, both the player and the dealer receive two cards. Players decide whether to draw more cards or keep their hand as it is. The dealer acts only after all player decisions are complete and follows fixed rules for every round.
The goal is to finish with a higher total than the dealer without exceeding 21. If a hand goes over 21, it is out for that round. Blackjack can be played in casinos or online.
So, how are the cards counted in the first place?
In blackjack, each card has a clear value. Numbered cards from 2 to 10 are worth their face value. For example, a 7 counts as seven points.
All face cards, Jack, Queen and King, each count as ten. The Ace is flexible because it can be worth either one point or eleven points, whichever makes the hand stronger without going over 21. A hand such as Ace and 7 can be 8 or 18, often called a soft 18 when the Ace is counted as eleven.
The best possible starting hand is a blackjack, made up of an Ace plus a ten-value card (10, Jack, Queen or King) as the first two cards. All other hands are simply ranked by their totals, as close to, but not over, 21. If a total goes above 21, the hand is bust.
With values in mind, it helps to see how a round unfolds from bet to result.
Each round begins with players placing a wager. The dealer then gives two cards to each player and two to themselves, with one of the dealer’s cards usually face up so everyone can see it.
Players review their totals and choose how to continue. Some prefer to add another card, while others keep their current total. Each player acts in turn until all decisions are made.
Only then does the dealer complete their hand. Dealers follow table rules that require them to draw until reaching a set total. Once the dealer finishes, hands are compared and the outcome is settled based on the totals.
From here, the choices available on a hand make a real difference to how the round develops.
In blackjack, players can shape the round through a few key options.
Hitting means asking for another card to move closer to a strong total. Players can take additional cards until they choose to stop or the hand goes over 21.
Standing means keeping the hand as it is and ending the turn. This is common when the total already looks competitive.
Double down allows the player to double the initial bet and receive exactly one more card before standing. It is only available on the first two cards and increases both potential return and the amount at stake.
Splitting can be used when the first two cards are of the same value, such as 8 and 8 or King and Queen. The pair is separated into two hands and an extra bet equal to the original is placed on the new hand. Each hand is then played separately. Some tables restrict re-splitting or limit split Aces to one additional card, so checking the table rules helps avoid surprises.
Next come two optional rules that only appear in specific spots and can change how a round is settled.
Insurance is offered when the dealer’s face-up card is an Ace. It is a separate side wager, usually half the original bet, placed on the dealer having a blackjack. If the dealer does have blackjack, the insurance bet typically pays 2:1. If not, the insurance bet is lost and the main hand continues as normal.
Surrender lets a player forfeit the hand after the first two cards in exchange for keeping half of the original stake. Not every table offers surrender, and rules vary by game, so it is worth confirming whether the option is available.
Understanding how the dealer must act next will make the rest of the round easier to follow.
Blackjack dealers follow strict procedures. In most games, the dealer draws cards until reaching at least 17 and then stands. Many tables require the dealer to stand on all 17s, including a soft 17 where an Ace counts as eleven. Some tables, however, require the dealer to hit on soft 17, and this will be shown on the table rules.
Dealers do not make discretionary choices; they apply the posted rules the same way every time. This consistency is what allows players to make informed decisions with the information on show.
Blackjack can be played with different numbers of decks. Some games use a single deck of 52 cards, while many use multiple decks, commonly six or eight. The deck count affects how often shuffling happens and the general pace of play. The rules and deck count are usually displayed clearly at the table or on the game screen.
With the structure of play clear, it is easier to understand how wins, ties and blackjacks are paid.
The outcome of the round determines how bets are settled. If a hand finishes higher than the dealer without going over 21, the player wins. A standard win usually pays 1:1, so a £10 stake returns £10 in winnings.
A push occurs when the player and dealer have the same total at the end of the round. In a push, the original stake is returned with no win or loss.
A blackjack, the Ace and ten-value starting hand, usually pays 3:2. With a £10 stake, that means £15 in winnings. Some tables pay differently, so it is always worth checking the paytable before joining a game.
