Blackjack is one of the most popular card games in any casino. The goal is simple. You try to get a hand closer to 21 than the dealer without going over. Better still, your decisions matter. A player who knows the basics faces one of the lowest house edges in the casino.
This guide explains how blackjack works in plain English. You will learn the card values, the player actions and the dealer rules. We also cover basic strategy, the effect of table rules and the mistakes that cost beginners money.
You do not need any experience to follow it. For other games, see our full set of casino game guides.
A Short History Of Blackjack
Blackjack has no single clear starting point. Most historians trace it to French card games played in the 1700s. The best known is Vingt-et-un, which means twenty-one. Related games such as Chemin de Fer and French Ferme also played a part.
The game later reached North America. American casinos wanted to make it more exciting. Some offered a special bonus payout of 10 to 1. It paid when a player held the ace of spades and a black jack. That bonus is long gone, yet the name stuck.
In 1962, a mathematician named Edward Thorp published a book called Beat the Dealer. It showed that smart play could cut the casino’s edge. The book became a bestseller and brought a wave of new players to the tables.
| Period | What changed |
|---|---|
| 1700s | Vingt-et-un is played in French casinos |
| 1800s | The game spreads to North America |
| Early 1900s | The name blackjack becomes common |
| 1962 | Edward Thorp publishes Beat the Dealer |
| Late 1990s onward | Online blackjack and live dealer games appear |
Today, blackjack is played all over the world. Online versions let you play at home, and live dealer tables bring a real dealer to your screen.
How Blackjack Works
You play against the dealer, not against other players. Other people at the table do not affect your hand. Here is a round from start to finish.
- Place your bet. Each table has a minimum and a maximum.
- The cards are dealt. You get two cards. The dealer gets two as well, with one face up.
- You play your hand. You can hit, stand and more. We explain each option below.
- The dealer plays. The dealer follows fixed rules and has no choices.
- Hands are compared. The higher hand that has not gone over 21 wins.
If you go over 21, you bust and lose at once. This is true even if the dealer would also have busted. That rule gives the casino its basic edge.
Card Values
| Card | Value |
|---|---|
| 2 to 10 | Face value |
| Jack, Queen, King | 10 |
| Ace | 1 or 11, whichever helps your hand |
A hand with an ace counted as 11 is called a soft hand. For example, an ace and a six make a soft 17. You cannot bust on the next card, because the ace can drop to 1. A hand without a flexible ace is a hard hand.
A blackjack is an ace plus a ten-value card as your first two cards. It beats any other 21. Most tables pay 3 to 2 on a blackjack. A R100 bet then wins R150. If both you and the dealer have blackjack, the round is a push, and you keep your bet.
Player Actions
| Action | What it means |
|---|---|
| Hit | Take another card |
| Stand | Keep your hand and take no more cards |
| Double down | Double your bet, take one more card, then stand |
| Split | Turn a pair into two hands, with a second bet of equal size |
| Insurance | A side bet offered when the dealer shows an ace |
| Surrender | Give up half your bet and end the hand, where allowed |
Not every table offers every action. Surrender, for example, is rare online. Always read the rules shown on the table or the game screen.
How The Dealer Plays
The dealer has no choices. The rules are fixed, and every table posts them. In most games, the dealer must hit until reaching 17 or more. Some tables make the dealer hit on a soft 17. Others make the dealer stand on every 17.
This small difference matters. A dealer who hits soft 17 adds a little to the house edge. For that reason, a table where the dealer stands on all 17s is better for you.
Basic Strategy
Basic strategy is a set of rules for every hand. It tells you the best play based on your hand and the dealer’s face-up card. Players have worked it out with computers, so it is not a guess. It will not make you win every hand. However, it gives you the lowest house edge possible.
The lists below are a simplified version. They suit most common tables.
Hard Hands
| Your hand | What to do |
|---|---|
| 8 or less | Hit |
| 9 | Double against a dealer 3 to 6. Otherwise hit. |
| 10 | Double against a dealer 2 to 9. Otherwise hit. |
| 11 | Double against a dealer 2 to 10. Otherwise hit. |
| 12 | Stand against a dealer 4 to 6. Otherwise hit. |
| 13 to 16 | Stand against a dealer 2 to 6. Otherwise hit. |
| 17 or more | Stand |
Soft Hands
| Your hand | What to do |
|---|---|
| Ace with 2 to 6 (soft 13 to 17) | Hit |
| Ace with 7 (soft 18) | Stand against a dealer 2, 7 or 8. Hit against a dealer 9, 10 or ace. |
| Ace with 8 or 9 (soft 19 or 20) | Stand |
Pairs
| Your pair | What to do |
|---|---|
| Aces and 8s | Always split |
| 10s and 5s | Never split. Play 10s as 20, and 5s as a hard 10. |
| 9s | Split, except against a dealer 7, 10 or ace |
| 7s | Split against a dealer 2 to 7 |
| 6s | Split against a dealer 2 to 6 |
| 2s and 3s | Split against a dealer 2 to 7 |
| 4s | Do not split. Hit. |
You can print a full chart and keep it next to you when you play online. Many players do. Casinos on the ground may or may not allow it, so ask first.
How Table Rules Change The Odds
Two blackjack tables can look the same and still cost you very different amounts. The rules matter a great deal. Check them before you sit down or open a game.
| Rule | Better for you | Worse for you |
|---|---|---|
| Blackjack payout | 3 to 2 | 6 to 5 |
| Dealer on soft 17 | Stands | Hits |
| Number of decks | Fewer decks | More decks |
| Doubling | On any two cards | Limited to some totals |
| Surrender | Allowed | Not allowed |
The blackjack payout is the biggest one. A table that pays 6 to 5 instead of 3 to 2 raises the house edge by more than one percentage point. Skip these tables whenever you can.
With good rules and basic strategy, the house edge is often around half a percent. Without strategy, it can climb to two percent or more. Take a player who bets R2,500 in total over an evening. At 0.5%, the expected loss is about R12. At 2%, it is about R50.
Blackjack Terms Explained
| Term | What it means |
|---|---|
| Bust | Going over 21, which loses the hand |
| Push | A tie, where your bet is returned |
| Hole card | The dealer’s face-down card |
| Upcard | The dealer’s face-up card |
| Shoe | The box that holds several decks and deals the cards |
| Soft hand | A hand with an ace counted as 11 |
| Hard hand | A hand with no ace, or an ace counted as 1 |
| Natural | Another word for a blackjack |
Popular Blackjack Variations
Most online casinos offer more than one type of blackjack. The rules change slightly in each one.
| Variation | What is different |
|---|---|
| Classic blackjack | The standard game with the usual rules |
| European blackjack | The dealer takes the second card only after you play |
| Spanish 21 | The 10s are removed from the deck, with bonus payouts to make up for it |
| Blackjack Switch | You play two hands and can swap the top cards between them |
| Multi-hand blackjack | You play several hands at once against one dealer hand |
| Live dealer blackjack | A real dealer deals the cards by video stream |
Stick to classic blackjack while you learn. Basic strategy changes with the rules, so a chart for one game may not fit another.
How Much Should You Bet?
Set your budget first, then choose a bet size to match. A common rule is to bet only a small part of your bankroll on each hand. For example, with R500, a bet of R10 or R20 gives you plenty of hands to play.
With a R25 bet, R500 gives you only 20 hands if you lose each one. With R10, you get 50 hands. Neither choice changes the odds. However, smaller bets let you play longer and handle bad runs.
Avoid betting systems. They raise your bet after a loss or a win. They may feel clever, but they do not change the house edge. They only make your swings larger.
Common Mistakes To Avoid
- Taking insurance. It costs you money in the long run. Skip it, even with a strong hand.
- Playing at 6 to 5 tables. The lower payout costs you a lot.
- Copying the table. Other players do not change your hand. Play by the chart.
- Standing on 12 to 16 against a high card. It feels safe, but hitting is correct.
- Splitting 10s. A hand of 20 is too strong to break up.
- Chasing losses. Raising your bets to win it back can drain your money fast.
- Playing without a plan. Decide your limit and stick to it.
Does Card Counting Work Online?
Card counting is a method of tracking the cards that have left the deck. It can give an expert a small edge in a land-based casino. However, it takes serious practice and a lot of concentration. Casinos also watch for counters and can ask them to stop playing.
It does not work in most online blackjack. Online games use a random number generator that effectively reshuffles after every hand. As a result, there is nothing to track. Live dealer games deal from a shoe, but casinos often shuffle early.
Blackjack Compared With Baccarat
| Feature | Blackjack | Baccarat |
|---|---|---|
| Your choices | Hit, stand, double, split and more | Pick a bet only |
| Skill | Strategy lowers the house edge | None |
| Best house edge | Often under 1% with good play | About 1.06% on the Banker bet |
| Pace | Slower, with more decisions | Fast and simple |

Playing Blackjack In South Africa
You will find blackjack tables in many land-based casinos in South Africa. They are licensed and regulated by the provincial gambling boards. You must be 18 or older to play.
Online blackjack is a different matter. The National Gambling Act of 2004 does not allow online casino gambling in South Africa. No South African online casino licence exists. Offshore sites accept South African players, but they are not licensed here. As a result, you have no local regulator to turn to if something goes wrong. Our online gambling laws guide explains the position in detail.
If you choose to play at an offshore site, read our online casino reviews first. They show the bonus rules and the licence details for each site.
Frequently Asked Questions
Is blackjack a game of skill or luck?
It is both. The cards are random, but your decisions change the result. Good play lowers the house edge.
What is the best hand in blackjack?
A blackjack, which is an ace plus a ten-value card, is the best hand. It beats any other total of 21.
Should I ever take insurance?
In the long run, no. It is a side bet with a higher cost than the main game. Basic strategy says to skip it.
What does a 6 to 5 table mean?
It means a blackjack pays 6 to 5, not 3 to 2. On a R100 bet, you win R120 instead of R150. Avoid these tables when you can.
Can I count cards online?
Not in any useful way. Most online games reshuffle after every hand, so there is nothing to count.
Is online blackjack legal in South Africa?
No. The National Gambling Act of 2004 does not permit online casino gambling, and no South African online casino licence exists. Land-based casinos are licensed by provincial gambling boards.
