Blackjack is the only game in any South African casino where, played correctly, you can reduce the house's mathematical edge to under one percent. That single fact is what separates it from every other table. It rewards study; nothing else on the floor does.
This guide covers the whole picture: the rules as they're actually dealt at Emperors Palace, Sun City, GrandWest and Montecasino; the basic strategy charts for hard hands, soft hands, and pairs; the bankroll discipline that keeps you in your seat long enough for the maths to work.
If you take one thing from this guide: the dealer's upcard tells you everything. Your first job is to make the right decision against it — not to chase a number.
How blackjack actually works
The goal is to beat the dealer's hand without going over 21. You're not playing the other players at the table; only the dealer. Every card has a value: number cards count as printed, face cards (Jack, Queen, King) count as 10, and the Ace counts as either 1 or 11 — whichever is better for you.
You'll be dealt two cards face up. The dealer takes one face up and one face down. Now you decide: hit, stand, double, or split. The dealer always plays last and follows fixed rules — typically standing on any 17, hitting any 16 or below.
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 powerful move with the right starting total.
- Split: If you're dealt two cards of the same rank, you can split them into two separate hands, each with its own bet.
For South African players
Most SA casinos deal blackjack from a 6-deck shoe. The dealer stands on soft 17. Blackjack pays 3:2 on most tables — but be aware that some 6:5 tables exist (especially at lower minimums), and the difference is enormous. Never play 6:5 blackjack. That single rule change adds roughly 1.4% to the house edge, which is more damage than every other rule combined.
Hard hands: the foundation chart
A "hard hand" is any hand without an Ace — or one where the Ace must count as 1 to avoid busting. These are the bread and butter of every session. Here's the optimal action for each:
| Your Hand | Dealer 2–6 | Dealer 7–8 | Dealer 9 | Dealer 10 | Dealer A |
|---|---|---|---|---|---|
| 8 or less | Hit | Hit | Hit | Hit | Hit |
| 9 | Double | 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 |
Notice the pattern. When the dealer is showing a weak card (2–6), they're more likely to bust. You can stand on stiff hands (12–16) and let them break. When the dealer shows a strong card (7–Ace), they'll probably make a strong hand — you have to take the risk and hit.
Soft hands: the flexible chart
A soft hand contains an Ace counting as 11. The defining feature: you can never bust on a single hit, because the Ace can drop to 1. This changes everything. Soft hands give you license to be aggressive.
| 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 | Stand | Hit |
| Soft 19–20 | Stand | Stand | Stand |
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 | Split (vs 9) |
| 8,8 | Always Split | Always Split | Always Split |
| 7,7 | Split | Hit | Hit |
| 5,5 | Never Split | Never Split | Never Split |
| 2,2 / 3,3 | Split | Hit | Hit |
Five rules that everyone breaks
- Never take insurance. No matter what your hand is. The bet has a 7%+ house edge.
- Always split Aces and 8s. Aces become two 11s. Eights become two fresh starts instead of a 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 sessions. Variance is unavoidable. The whole point of bankroll discipline is to keep playing long enough for the math to come good. Some practical rules for SA players:
- Bring at least 40–50 times your minimum bet as your session bankroll. R2,000 for a R50 table.
- Set a session loss limit before you sit down — and walk when you hit it.
- Set a profit-taking target — and lock in some of it before chasing more.
- Bet flat. Don't increase bet size after losses. That's not strategy; that's the casino's plan.
- Take breaks. Fatigue is the most reliable predictor of strategy mistakes.
