Blackjack is the highest-RTP casino game widely available in South Africa. Played correctly with basic strategy, it returns 99.5% over the long run. The 0.5% house edge is the lowest in the building. Played wrong, you bleed money fast. This page covers the rules, basic strategy, the variants you’ll see at SA casinos, and the side bets that quietly steal your edge.
The rules in one minute
- You play against the dealer, not other players.
- Aim: get a hand total closer to 21 than the dealer, without going over.
- Number cards are face value, face cards (J/Q/K) are 10, Ace is 1 or 11.
- Bust (over 21) = automatic loss.
- Blackjack = Ace + 10-value card on first two cards. Pays 3:2 (some tables 6:5, avoid those).
- Dealer must hit on 16 and stand on 17. (Some variants hit on soft 17.)
The five actions you can take
| Hit | Take another card. Use when your hand total is low or the dealer’s up-card is strong. |
| Stand | Keep your current hand. Use when you’re at 17+ or when the dealer’s up-card is weak (5 or 6). |
| Double down | Double your bet, take exactly one more card. Best on 11. Strong on 10 vs dealer’s 2-9. |
| Split | Split a pair into two hands, double the bet. Always split Aces and 8s. Never split 10s or 5s. |
| Surrender | Forfeit half your bet, end the hand. Available on some tables. Best on hard 16 vs dealer’s 9, 10, A. |
Basic strategy: the rules that get you to 99.5%
Basic strategy is a mathematically optimal play for every combination of your hand and the dealer’s up-card. It’s been computed by simulation and is the closest thing to a “right answer” that a casino game offers. You don’t have to memorise the full chart for an online table because you can have it open beside you. But if you want to play live blackjack at a brick-and-mortar SA casino, learn it.
The simplified version covers about 95% of decisions:
- Always hit on hard 8 or less.
- Always stand on hard 17 or more.
- Hit hard 12 to 16 against dealer’s 7+. Stand on 12 to 16 against dealer’s 2-6.
- Always double on 11.
- Always split Aces and 8s.
- Never split 5s, 10s.
- Never take insurance. The 7% house edge on the side bet ruins your overall RTP.

Side bets: the trap
Side bets like 21+3, Perfect Pairs, Lucky Ladies, Buster Bet are tempting because they pay big multiples. They also have terrible RTP, often 90 to 95%, sometimes worse.
Honest read: the main blackjack hand is the best bet on the casino floor at 99.5% RTP. Adding a 92% RTP side bet drags your overall RTP down significantly. Skip them.

Blackjack FAQ
Is blackjack the best casino game by RTP?
For commonly available games, yes. Blackjack with basic strategy returns 99.5% over the long run. Some video poker variants run higher with perfect play but require more memorisation.
Can you count cards online?
Not on RNG blackjack. The deck is shuffled after every hand. On live blackjack, the shoe gets changed and reshuffled often (typically 50% penetration), making counting unprofitable. Online live blackjack is not a counting environment.
Should I take insurance?
No. Insurance is a side bet that pays 2:1 if the dealer has blackjack. The math gives the casino a 7% edge on insurance. Skip it every time, even when you have blackjack yourself.
What does 6:5 blackjack mean?
The blackjack payout. Standard tables pay 3:2 (a R10 blackjack wins R15). 6:5 tables pay R12 for the same R10 blackjack. The 6:5 reduction lifts the house edge from 0.5% to about 1.9%. Avoid 6:5 tables.
Why does the dealer always hit on 16?
The rules of the game. Dealer plays a fixed strategy: hit until reaching 17 or higher. They have no choice. This is the structural disadvantage they accept (the dealer busts ~28% of the time on a 16). The house edge comes from the player having to act first, so a player who busts loses immediately even if the dealer would have busted too.
Is online blackjack legal in South Africa?
Yes, at licensed operators. The Western Cape Gambling and Racing Board, Mpumalanga Gambling Board and other provincial boards license online casino with blackjack. All seven operators we review carry blackjack tables under their respective licences.
