Blackjack is one of very few casino games where, played correctly, you can bring the house edge below one percent. That is what sets it apart from the rest of the floor: it rewards study. Roulette is the same however long you have played, and slots are the same however clever you are. Blackjack is different, and the difference is worth understanding.
This guide covers the rules you are likely to find at SA casinos such as Emperors Palace, Sun City, GrandWest, Montecasino and Suncoast; the full basic strategy charts for hard hands, soft hands and pairs; the bankroll discipline that keeps you at the table long enough for the maths to work; a realistic look at card counting; and the mistakes that cost recreational players the most over time.
If you take one thing from this guide: the dealer's upcard tells you almost everything. Your first job is to make the right decision against it, not to chase a total.
How blackjack actually works
The goal is to beat the dealer's hand without going over 21. You are not playing the other players, only the dealer. Number cards count as printed, picture cards (Jack, Queen, King) count as 10, and the Ace counts as 1 or 11, whichever suits you better.
You are dealt two cards face up. The dealer takes one face up and one face down (the "hole card"). Then you decide: hit, stand, double or split. The dealer plays last and follows fixed rules, usually standing on 17 or more and hitting 16 or less, with no choice in the matter. That is why basic strategy works: you make decisions, but the dealer behaves like a machine, and the charts in this guide give the best decision against that machine.
The four actions, explained
- Hit: Take another card. You can keep hitting until you stand or bust (go over 21).
- Stand: Keep your current total. The dealer will play their hand.
- Double: Double your bet and take exactly one more card. A strong play with the right starting total, usually a hard 9, 10 or 11 against a weak dealer card.
- Split: If you're dealt two cards of the same rank, you can split them into two separate hands, each with its own bet equal to the original.
Some tables also offer Surrender (forfeit half your bet to escape a bad hand) and Even Money (take a 1:1 payout when you have blackjack and the dealer shows an Ace). Most SA casinos do not offer Surrender on regular blackjack tables. Even Money is mathematically identical to taking insurance and is generally a poor decision for the same reason.
For South African players
The charts below assume a 6-deck shoe with the dealer standing on soft 17, a common setup, but rules vary by casino and table, so check the felt or ask the dealer. Blackjack should pay 3:2. Some tables pay 6:5, and the difference is huge. Never play 6:5 blackjack. That one change adds roughly 1.4% to the house edge, more than every other common rule change combined. If a table doesn't show its payout clearly, ask before you sit down.
Why the dealer's upcard matters more than yours
This is the most important idea in blackjack. The dealer's upcard tells you what they are likely to finish with, and that, not just your own total, decides what you should do.
A dealer showing 2, 3, 4, 5 or 6 has a "weak" upcard and busts roughly 35% to 43% of the time, depending on the card. A dealer showing 7, 8, 9, 10 or Ace has a "strong" upcard and busts much less often, from about 26% with a 7 down to about 12% with an Ace, making 17 or better the rest of the time.
That changes how you play. Against a weak upcard, you can stand on hands you would normally hit and let the dealer bust. Against a strong upcard, you have to take risks, hitting hands that might bust, because standing on a low total against a strong dealer loses more often.
Hard hands: the foundation chart
A "hard" hand is any hand without an Ace, or one where the Ace has to count as 1 to avoid busting. Most hands you play will be hard totals, so learn this chart first.
| Your Hand | Dealer 2–6 | Dealer 7–8 | Dealer 9 | Dealer 10 | Dealer A |
|---|---|---|---|---|---|
| 8 or less | Hit | Hit | Hit | Hit | Hit |
| 9 | Double 3–6 / Hit 2 | Hit | Hit | Hit | Hit |
| 10 | Double | Double | Double | Hit | Hit |
| 11 | Double | Double | Double | Double | Hit |
| 12 | Stand* | Hit | Hit | Hit | Hit |
| 13–16 | Stand | Hit | Hit | Hit | Hit |
| 17 or more | Stand | Stand | Stand | Stand | Stand |
* Hit 12 against dealer 2 or 3; stand against 4, 5, 6.
Notice the pattern. When the dealer shows a weak card (2 to 6), they are more likely to bust, so you can stand on stiff hands (12 to 16) and let them. When the dealer shows a strong card (7 to Ace), they will probably make a good hand, so you have to hit even when you might bust.

Soft hands: the flexible chart
A soft hand contains an Ace counted as 11. Because the Ace can drop to 1, you can never bust on one more card. That lets you play soft hands more aggressively, doubling or drawing to improve totals you couldn't safely chase with a hard hand.
| Your Hand | Dealer 2–6 | Dealer 7–8 | Dealer 9–A |
|---|---|---|---|
| Soft 13–14 (A,2 / A,3) | Double* | Hit | Hit |
| Soft 15–16 (A,4 / A,5) | Double* | Hit | Hit |
| Soft 17 (A,6) | Double* | Hit | Hit |
| Soft 18 (A,7) | Double 3–6 / Stand 2,7,8 | Stand | Hit |
| Soft 19–20 | Stand | Stand | Stand |
* Double soft 13–14 (A,2 / A,3) against dealer 5–6; soft 15–16 (A,4 / A,5) against 4–6; soft 17 (A,6) against 3–6. Otherwise hit.
Soft 18 (Ace, 7) catches out more recreational players than any other hand. It feels strong, so they stand. But against a dealer 9, 10 or Ace, soft 18 loses more than it wins, and the right play is to hit. If you draw a 10, the Ace drops to 1 and you still have 18, so the hit can't make your total worse and may well improve it. Most players stand anyway, and it costs them over time.
Pairs: when to split
Splitting is one of the most misunderstood actions in blackjack. Get it right and you turn one weak hand into two playable ones. Get it wrong and you double your loss on a hand you should have folded into.
| Your Pair | Dealer 2–6 | Dealer 7–8 | Dealer 9–A |
|---|---|---|---|
| A,A: Aces | Always Split | Always Split | Always Split |
| 10,10 | Never Split | Never Split | Never Split |
| 9,9 | Split | Stand vs 7 / Split vs 8 | Split vs 9 / Stand vs 10, A |
| 8,8 | Always Split | Always Split | Always Split |
| 7,7 | Split | Split vs 7 / Hit vs 8 | Hit |
| 6,6 | Split | Hit | Hit |
| 5,5 | Never Split (treat as 10) | Never Split | Never Split |
| 4,4 | Hit (split vs 5,6) | Hit | Hit |
| 3,3 | Split | Split vs 7 / Hit vs 8 | Hit |
| 2,2 | Split | Split vs 7 / Hit vs 8 | Hit |
All charts on this page are standard basic strategy for 6 decks, dealer stands on soft 17, double after split allowed, no surrender (checked against Wizard of Odds). Without double after split, split 2s and 3s only against 4–7, and don't split 4s.
The two rules from this chart every player should remember: always split Aces and 8s, never split 10s. Splitting Aces gives you two hands starting at 11, the best possible start. Splitting 8s breaks up 16, the worst hand in the game, into two fresh starts. Splitting 10s breaks up 20, the second-best total there is. Don't give that up for two unfinished hands.
Side bets: a quick note
Most SA casinos now offer side bets on blackjack tables: Perfect Pairs, 21+3, Lucky Lucky, Buster Blackjack and others. They look fun. They have flashing animations. They occasionally pay 100:1 or more on rare combinations. They are also, without exception, terrible bets. House edges on blackjack side bets typically range from 5% to 15%, which is between 10 and 30 times worse than the main blackjack hand. The casino offers them because they convert recreational players who don't realise they're paying a tax for the privilege of dopamine.
The same goes for the best-known side bet of all, insurance, which we cover below. Skip them all and bet only the main hand.
Insurance: always decline
When the dealer's upcard is an Ace, you will be offered insurance: a side bet that pays 2:1 if the dealer has a 10-value card underneath, giving them blackjack. Many recreational players take it every time. They shouldn't.
The maths: 16 of the 52 cards in a deck are worth 10 (the tens, jacks, queens and kings), roughly 31%. A bet paying 2:1 needs to win a third of the time to break even. That gap gives insurance a house edge of about 7.4% in a 6-deck game, one of the worst bets on the floor. The exception is a skilled card counter tracking how many 10-value cards remain; when they make up more than a third of the shoe, insurance becomes worth taking. If you don't count cards, decline insurance every time.
Card counting: realistic expectations
Card counting works, but it is much harder, slower and less welcome than the films suggest. The idea is simple: track the balance of high cards (10s and Aces) to low cards (2s to 6s) left in the shoe, and bet more when high cards are plentiful, because those shoes favour the player.
The most common technique is Hi-Lo: you assign +1 to every low card seen (2–6), -1 to every high card (10s and Aces), and 0 to neutral cards (7–9). Track the running count throughout the shoe. Convert to a "true count" by dividing by the number of decks remaining. Bet bigger when the true count is positive, minimum when it's negative. Played perfectly with proper bet variation, this gives the player roughly a 0.5–1.5% edge over the casino.
The catches: multi-deck shoes dilute the count and shrink the edge, casinos may shuffle early to disrupt counting, staff are trained to notice changes in bet size, and casinos can refuse to deal to suspected counters. The edge is small even for a skilled counter in a good game, and it takes hundreds of hours of practice to earn a modest hourly return.
The realistic conclusion: card counting is fascinating and mathematically real, but it is not a way to make a living for almost anyone. Learn basic strategy first and master it. Only think about counting if you enjoy the challenge for its own sake, not because you expect it to make you rich.
Five rules everyone breaks
- Never take insurance. No matter what your hand is. Even if you have blackjack yourself. The bet has a 7%+ house edge.
- Always split Aces and 8s. Aces become two hands starting at 11. Eights become two fresh starts instead of one brutal 16.
- Never split 10s. Twenty is one of the strongest hands in blackjack. Don't break it for two unfinished ones.
- Always stand on hard 17 or higher. The bust risk dwarfs any improvement upside.
- Double 11 against any dealer card except an Ace. One of the most profitable single decisions in the game.
Bankroll: how to not go broke
Even with perfect basic strategy, you will lose some sessions. Variance can't be avoided. The point of bankroll discipline is to keep you playing long enough for the maths to even out, and to make sure that when it doesn't, you leave with something rather than nothing.
Session bankroll sizing
Bring at least 40 to 50 times the table minimum as your session bankroll: R2,000 for a R50 table, R4,000 for a R100 table. That cushions normal swings. A run of six losing hands feels bad, but with 40 units it is only 15% of your bankroll, which leaves plenty of room.
Stop-loss and stop-win discipline
Set a session loss limit before you sit down; half your session bankroll is sensible. Set a profit target too, also half. When you hit either one, leave. The hardest part of blackjack isn't the strategy; it's leaving when you said you would.
Flat betting versus progression
Bet the same amount every hand, whatever has just happened. Progressive systems (Martingale, Paroli, 1-3-2-6) feel as if they should work, but they don't beat the house edge; they only change the pattern of your wins and losses. Flat betting at the table minimum gives you the smallest swings, the least stress and the longest sessions.
Avoid alcohol
SA casinos comp drinks to keep you at the table. Take the comp soda. Skip the wine. Strategy errors compound; one drink leads to two, two leads to a hit on 16-against-6, and 16-against-6 leads to chasing losses. The free drinks are not actually free.
Where to play blackjack in South Africa
Blackjack tables are available at South Africa's major licensed casinos, including Sun City, GrandWest, Emperors Palace and Montecasino. Table minimums, the number of decks, payouts and dealer rules vary by casino and table and change over time, so check the rules printed on the felt (or ask the dealer) before you sit down, and walk past any table paying 6:5 on blackjack.
Some SA bookmakers also offer live-dealer blackjack online. Online casino-style games are not licensed as such in South Africa, and whether licensed bookmakers may offer them is disputed after a 2025 Supreme Court of Appeal ruling (see our gambling laws guide). Basic strategy works the same way wherever the rules match the chart above.
The tournament player's brief note
Blackjack tournaments call for a different strategy from normal play. The goal is to finish with more chips than the others at your table, not to get the best expected value from each hand, so you sometimes make plays that would be wrong in a normal game. If you are learning, focus on normal play first and treat tournaments as a later step.
Common mistakes I see at SA tables
The mistakes recreational players make most often are well documented. The biggest:
- Hitting 12 against a dealer 4, 5 or 6. Players panic at 12 and hit "to improve". But the dealer is more likely to bust than they are to improve to 17+. Stand and let the dealer break.
- Standing on soft 18 versus dealer 9, 10 or Ace. 18 feels strong. Against a strong dealer card, it isn't. You hit.
- Splitting 10s "because the dealer looks weak". 20 is too strong to break.
- Doubling on hard 12 because the dealer shows 5 or 6. Some recreational players misinterpret strategy and double-down on stiff totals. You don't double on 12. You stand.
- Increasing bet size after losses. The hand has no memory. Past losses do not affect future probability.
