How to Play Blackjack: Rules and Tips

Blackjack may seem complicated at first, but its basic format is easy to learn. This Al Buraq Regina guide covers the rules, card values, odds, payouts, table actions, and more. Read on to understand the game before betting against the dealer.

Basic Blackjack Rules: How to Play Blackjack

To win at Blackjack, build a hand as close to 21 as possible without going over. The dealer also tries to approach 21, so the hand nearer that total generally has the better chance of winning. Going over 21 means you bust and lose. If your total matches the dealer’s, the result is a tie called a push.

Blackjack is played with multiple decks, most often six, though tables may use anywhere from one to eight. After you place your first wager in the betting box, the dealer gives each player and themself two cards. All cards are dealt face up. Add the values of your cards and decide whether to take another card to get as close to 21 as possible. You can keep taking cards until you stand, reach 21, or exceed 21 and bust.

At a land-based casino, as many as six other players may sit at your table, with the dealer opposite. Players compete against the dealer rather than one another. Play moves from left to right, then the dealer takes a turn. A winning hand typically pays 1:1, returning your stake and awarding the same amount in winnings. For example, a winning $50 stake returns the original bet plus $50 in winnings.

The key exception is a “blackjack”, a two-card 21 formed with an Ace and a ten-value or face card. This hand most commonly pays 3:2; check the displayed payout before playing.

A typical table might have a $5 minimum bet and a $500 maximum. Limits vary by casino and table, but these are common examples.

Blackjack Odds and House Edge

The odds of winning at blackjack are close to 50%, with estimates of 46–48% often cited. They are not exactly 50/50 because the player acts first and can bust by exceeding the limit before the dealer takes a turn.

Using basic blackjack strategy, the house edge is stated as 0.5%. In practice, this means choosing the mathematically correct action for your hand in relation to the dealer’s hand, as explained in more detail below.

Put another way, a 0.5% house edge means many blackjack tables have a 98.5% RTP. This RTP (return to player) is described as the highest among casino games. For comparison, the lowest listed house edges for other games are:

  • Baccarat: 1.06%.
  • Video poker: From 0.76% to more than 5%, depending on the game.
  • Roulette: 2.70% for European and French versions, or 5.26% for American Roulette.
  • Video slots: From 1% to around 12%, depending on the game.

Note: Blackjack’s lower house edge helps explain its popularity at many casinos. It may offer a better chance over an extended period, but it cannot guarantee a win.

Blackjack Card Values

To reach 21, start by learning the value of each card. Number cards are worth their face value: a three counts as 3, and a six as 6. Jacks, Queens, and Kings are face cards, each worth 10. An Ace may count as 1 or 11, depending on the player’s choice and whether the hand can take that value without exceeding 21.

An Ace with a 7 can count as either 8 or 18; choose the total that works for your hand. If you then draw a 4, the Ace automatically counts as 1, making the total 7 1 4 = 12. An opening Ace is useful because it can be valued at 1 if a high card follows. The strategic details are covered below.

Essential Blackjack Terms

A number of terms come up regularly during a blackjack round. Here are some you are likely to hear:

  • Hit – Ask the dealer for another card.
  • Stick / Stand – Keep your current hand without taking another card.
  • Bust – Take a card that puts your hand total over 21.
  • Push – Tie the dealer’s score and get your original stake back.
  • Split – When the first two cards have the same value, such as 2 6s or 2 Jacks, you can divide them into two hands. Each hand receives a new card, and each requires an additional wager.
  • Double down – Double your original bet in exchange for one more card.
  • Surrender – Give up your hand before playing it and receive 50% of your original bet back.
  • Soft hand – A hand that counts an Ace as 11.
  • Blackjack – Make 21 with just two cards: an Ace and a 10 or face card. Blackjack usually pays 3:2.

For more terms, see our Blackjack Glossary and Terminology.

Basic Blackjack Actions

Standard blackjack tables generally offer the following choices. Which actions are available depends on your hand and the situation:

  • Hit: Select “hit” to ask the dealer for another card. You may keep hitting as long as your total is 21 or less.
  • Stand: When you “stand,” you end your turn with your current hand and take no more cards. You might stand when your total looks strong enough to challenge the dealer or another card could take you over 21.
  • Double down: “Double down” means doubling your initial bet and taking one more card. Players usually consider it when their hand looks promising and raising the stake could increase the potential return.
  • Split: “Split” turns a pair into two hands, each requiring an additional bet. You may be able to split cards of the same rank or a pair that could make strong hands. Eligible pairs and the permitted number of splits vary by blackjack version.
  • Surrender: When you “surrender,” you give up your hand and get half your original bet back. Depending on the blackjack variation, surrender may be early or late. It is generally considered when your hand has little chance of winning and limiting your loss is preferable.

How a Blackjack Round Works

Once players place their original wagers in the betting boxes or circles, the dealer gives each player two face-down cards. The dealer also gets two cards, one face up. You win by finishing with a higher total than the dealer without going over 21. After looking at their cards, players can hit, stand, or surrender. Turns move from left to right around the table; the dealer plays after everyone else. You are competing against the dealer, not the other players.

Early surrender means giving up before taking any additional cards. If the option is available and you use it, you get half your original bet back.

Players can draw more cards until they reach 21, exceed that total and lose, or decide to stand. After players have finished, the dealer reveals the second card and plays according to the table’s rules. Under the “17” rule, the dealer must stand upon reaching 17; at 16 or less, another card is required. This set procedure gives the dealer fewer choices than the player.

After the dealer finishes, the hands are compared and winning players are paid. If the totals tie, the result is a push and the original bet is returned.

Hard and Soft Hand Rules

Check the dealer’s hard- or soft-hand rules before playing at an online or land-based blackjack table. “S17” and “H17” refer to different dealer procedures when holding a soft 17—a hand with an Ace counted as 11. The rule can influence the house edge and player decisions. Here’s what each means:

S17 (Stand on Soft 17)

At an S17 table:

The dealer stands on soft 17. If the dealer has an Ace plus cards worth 6, such as Ace-6 or Ace-2-4, they do not take another card and stand on 17.

This rule benefits players because a dealer starting with a weaker hand has a greater chance of busting, or going over 21. It also lets players make more cautious decisions after considering the dealer’s upcard.

H17 (Hit on Soft 17)

At an H17 table:

The dealer must hit soft 17. So, if the dealer has an Ace and cards worth 6, they take another card.

This rule is less favourable to players because the dealer gets another chance to improve their hand. It lowers the chance that the dealer will bust from a weak starting hand.

Note: S17 tables are often viewed as more favourable to players because the dealer stands on a soft total, potentially increasing the chance of a bust. H17 rules let the dealer try to improve the hand. Check the applicable rule before playing blackjack online or in a casino, as it can affect strategy and winning odds. Many players prefer S17 for its slightly better odds, but adapt your play to the table’s rule.

How Many Decks Are Used?

Along with hard- and soft-hand rules, check how many decks the table uses. The deck count can affect the house edge and strategy; in general, fewer decks are more favourable to the player.

  • Single-deck game: A one-deck table has the lowest house edge and is easier for anyone considering card counting. To offset these advantages, single-deck games often have stricter conditions, such as limits on when you can double down or split.
  • Double-deck game: Double-deck games occasionally appear at online casinos. They may offer better odds than games with more decks, while having more liberal rules than single-deck games.
  • Multiple-deck game: Many blackjack tables use multiple decks, usually four to eight shuffled together. Casinos often favour this format because it makes card counting harder and raises the house edge.

Players often have little say in how many decks are used. Online casinos and land-based casinos in Las Vegas and other major gambling destinations commonly offer multiple-deck games with four or more decks. If you find a single- or double-deck table,

Blackjack Insurance

Insurance is an optional side bet offered when the dealer’s upcard is an Ace. It pays 2:1 if the dealer has blackjack—an Ace and a 10-value card. The insurance wager is usually capped at half of your original bet.

For example, if your original bet is $10, your insurance wager would be $5. If the dealer has blackjack, your original $10 bet loses, but insurance pays $10, for a net loss of $5. If the dealer does not have blackjack, you lose the insurance wager but can continue playing your original hand.

Insurance is intended to protect your original wager if the dealer has blackjack. However, the odds generally favour the house, so insurance is usually discouraged. It is a negative-expectation bet: over time, a player who takes it is expected to lose more often than win.

Splitting Blackjack Hands

You can split if your starting hand meets the table’s requirements. Splitting turns your original cards into two hands, each requiring its own wager and increasing your total stake. Rules vary between blackjack versions, so check them before playing.

  • Splitting Tens: Jacks, Queens, Kings, and 10s are each worth ten points. Many online casinos allow these cards to be split, but some require identical ranks—for example, two Kings or 10s—instead of allowing a King and a 10 to be split.
  • Resplitting: Some tables let you split a pair again, often up to three times per hand. Rules elsewhere may permit one split, six splits, or unlimited splits. For instance, you might split a pair of 8s, then split again if another eight is dealt to one of the resulting hands.
  • Resplitting aces: This uncommon rule is generally associated with Late Surrender games.
  • Taking another card after splitting aces: Usually, splitting Aces allows only one drawn card per Ace. Some versions lift that restriction and let you keep drawing.
  • No splitting aces: This rare rule prohibits splitting Aces. If it applies, you may prefer to avoid that version of blackjack.
  • Split Anytime: This option allows a player to split after taking a hit. For example, if your cards are 10 and 2, and you draw another 2 on a hit, you can split the deuces into separate hands.
  • Split any 16: This lets you split any combination totalling 16, regardless of the individual cards, including 10 and 6, Ace and 5, or 9 and 7.
  • No Splits on 4, 5, or Ten: This rule applies at UK casinos.
  • Discard split hand: This uncommon but useful rule lets you discard one of the hands created by a split.

Doubling Down

Doubling down lets you double your initial bet in return for one more card. You can make this decision only after receiving your first two cards and before taking any more. The aim is to increase a potential payout on a strong hand or improve a hand that could beat the dealer.

The advantage is a chance to win more on a hand that looks strong. It can also increase your return when your hand seems likely to win.

The downside is that doubling also raises the risk of busting—going over 21 and losing the entire bet. It can be costly if your hand is weaker than expected.

Consider the dealer’s upcard before doubling down. Doubling on a total of 10 or 11 is generally considered useful when the dealer shows a low card, such as 2–6.

Blackjack Tips

Blackjack still involves considerable chance. You cannot control the cards dealt to you or the dealer, and card counting is not possible in software games. You can, however, make informed choices and manage how you play. Here are 10 tips to consider.

  • Practise for free: Try an online casino’s practice mode to get familiar with the game before risking your own money.
  • Use a strategy chart: Keep a basic blackjack strategy chart handy online to check the recommended play for your situation.
  • Set a budget: Decide how much you will spend on blackjack before you start, and stick to that limit.
  • Pick a suitable table: Look for a table where the minimum bet is no more than 5% of your budget.
  • Follow basic strategy: Hit totals below 17 when the dealer shows 8, 9, 10, or a face card; stand on totals above 11 when the dealer shows 4, 5, or 6.
  • Avoid insurance: Insurance against a dealer blackjack is widely considered a “sucker’s bet” and is generally best avoided.
  • Use doubling down strategically: Double down on a ten-value card when the dealer’s upcard is nine or lower, or on any hand totaling eleven.
  • Know when to split: If you have two cards of equal value, split by matching your original bet. Avoid splitting 10s or 5s, but split 7s or 8s when the dealer has a lower-value hand.
  • Use progressive betting: Some players increase bets during a winning streak and lower them during a losing streak, but this does not change the underlying odds.
  • Try live dealer games: Live dealer games let you observe the table more closely and may allow card counting, unlike casino software games. Casino rules and policies still apply.

Blackjack Basic Strategy

To make better decisions during blackjack sessions, use basic strategy. These guidelines compare your cards with the dealer’s upcard to identify the mathematically preferred action. Players often refer to a blackjack strategy chart for each situation. Following one can reduce the casino’s advantage, but it cannot remove the house edge or guarantee a win.

Your hand and the dealer’s exposed card help determine whether to hit, stand, double down, split, or surrender.

Basic strategy involves many details. Our Blackjack Strategy Charts article explains how to play more effectively. Its key principles include:

  • Always hit on a hand worth 12 or less.
  • Always stand on a total of 17 or higher.
  • For totals from 13 to 16, consider the dealer’s upcard.
  • With a total in that range, stand if the dealer shows 2 through 6.
  • Conversely, hit if the dealer’s upcard is 7 through Ace.

There are additional decisions about doubling down, which doubles your bet, and splitting pairs, which turns two cards of equal value and type into separate hands. Review the complete basic strategy to learn when each action is recommended.

Blackjack Pros and Cons

Like every casino game, blackjack has advantages and disadvantages. In our view, its benefits can compare favourably with those of other table games. Skill does not determine every outcome, but informed decisions may help reduce avoidable losses.

Advantages of Playing Blackjack

Blackjack can offer players these advantages:

  • Low house edge: With suitable strategy, blackjack is known for having one of the lower house edges among casino games. Skilled players may reduce the edge to under 1%, making the game relatively favourable, though never risk-free.
  • Skill-based play: Unlike games driven mostly by luck, blackjack gives players meaningful decisions. Learning and applying basic strategy can improve the mathematical odds.
  • Different versions: Traditional and online casinos offer many blackjack variations. You can compare their rules, formats, and odds to find one that suits your preferences.
  • Social play: Land-based blackjack is often played at a table with other people, creating an interactive atmosphere. Many online versions also offer a chatroom that adds to the table experience.
  • Potential to profit: Skilled players who use strategy and card counting may profit in favourable conditions, but there is no guarantee. Blackjack’s relatively low house advantage may make it appealing to professional gamblers, but it does not provide reliable income.

Disadvantages of Playing Blackjack

Even if you know blackjack well, keep these drawbacks in mind:

  • House rules: Casino rules vary, and small differences can affect both the house edge and the right strategy. Adjust your play to the conditions at the table.
  • Card counting is difficult: Card counting may work in some circumstances, but it is hard to learn and apply. Casinos also use measures to spot and discourage it.
  • Emotional pressure: Losing streaks and poor decisions can make blackjack stressful. Staying disciplined and managing your reactions are important.
  • House advantage: Even when the edge is low, the casino retains a long-term advantage. Over time, players are expected to lose more than they win.

Getting Started with Blackjack

Many online casinos offer blackjack for beginners, experienced players, and high rollers. Beginners can look for low stakes and a generous welcome bonus, while free blackjack games provide a way to practise before wagering real money. This can be a sensible way to get started.

Splitting, doubling down, surrendering, and the value of the Ace add rules to learn, but the basic blackjack format is easy to follow. That makes the game accessible to people new to online gambling. Learn the rules, practise responsibly, and decide whether the game is right for you.

Online Blackjack Table Game Variations

Online blackjack offers a wider selection of variations than a brick-and-mortar casino. Tables commonly offer standard formats at different betting limits, including games that use both S17 and H17 rules.

Online casino software and live game providers can create formats that might not be available at land-based casinos. These versions introduce different features while keeping blackjack’s basic structure. Once you know standard blackjack, many variations are easier to understand.

Examples of blackjack games offered at online casinos include:

  • All Bets Blackjack (Playtech Live): This format is for players who want side bets. It uses eight decks and offers seven side bets, which can be wagered separately from the main hand. Each side bet has its own RTP, and its house edge is higher than that of the main game.
  • Infinite Blackjack (Evolution): This live casino format uses unlimited-seat technology, so players do not have to wait for a seat as they might at a 7-seat blackjack table. Everyone plays the same hand dealt by the dealer. One trade-off is that other players’ cards do not provide useful information. Infinite Blackjack also offers four side bets.
  • Blackjack Switch: This variation lets players exchange cards between two hands. Each player plays two hands in the same round and can “switch” the top cards. The extra feature comes with different rules: a dealer total of 22 pushes all hands that have not busted, and a “Blackjack” pays 1:1 instead of 3:2.
  • Free Bet Blackjack (Evolution): This live format offers free bets for certain doubles and splits. You can double when your first two cards total 9, 10, or 11, and you may get an extra free split if a previous split produces another pair. If the dealer’s hand totals 22, it is a push, offsetting those free bets.
  • Random Multiplier Blackjack (multiple providers): Several live casino providers offer games with random multipliers, including Lightning Blackjack (Evolution) and Quantum Blackjack (Playtech Live). Lightning Blackjack has a side bet that pays 2x to 25x the stake after two consecutive winning hands. Quantum Blackjack uses three random cards with a 10x multiplier value that can stack to create a larger bonus payout.
  • These are just some of the blackjack variations available online.

Blackjack FAQs

What are the basic rules of blackjack?

Blackjack’s rules are relatively straightforward. You play against the dealer, who gives each player two face-up cards and takes two hole cards: one face up and one face down. During the round, players choose actions to bring their combined card value as close to 21 as possible without busting.

What are the odds of winning at blackjack, and what is the house edge?

The chance of winning an individual Blackjack hand is around 46–48%, close to even money. With basic strategy, Blackjack’s house advantage is lower than that of other casino table games. Making the recommended decisions can bring the house advantage to around 0.5%, giving Blackjack an optimal RTP of 99.5%.

What is the best way to win at blackjack?

Basic strategy gives players the best mathematical chance of success, but it cannot guarantee a win. Fewer decks may also lower the house advantage, while early or late surrender lets you return half of your original wager. A betting system such as Martingale does not remove the underlying risk or guarantee a profit.

How do you choose a blackjack table?

Choose table limits that suit your bankroll, and check the minimum and maximum bets. Review the number of decks, available side bets, and rules such as S17 and H17. Fewer decks may be preferable, but compare the complete set of table rules.

What do S17 and H17 mean in blackjack?

S17 and H17 are dealer rules for Blackjack tables. They determine what the dealer does with a soft 17, where an Ace counts as 11 and the hand totals 17. Under H17, the dealer hits; under S17, the dealer stands.
