The goal of blackjack
Blackjack is a game of you versus the dealer, not the other players. The aim is to finish with a hand that totals closer to 21 than the dealer’s – without going over 21, which is a “bust” and an instant loss. If your total beats the dealer’s, you win even money; if you both tie, it is a “push” and your stake is returned.
The reason blackjack is worth learning is its house edge of about 0.5% with correct play – the best value on the casino floor. Get the strategy wrong and that edge can climb past 2%, so the rules below are where the money is.
Card values
| Card | Value |
|---|---|
| 2 – 10 | Face value |
| Jack, Queen, King | 10 |
| Ace | 1 or 11 (whichever helps) |
A hand with an ace counted as 11 is a soft hand (e.g. Ace-6 is “soft 17”), because you cannot bust by taking another card – the ace drops to 1. A hard hand has no ace, or an ace forced to 1.
How a hand plays out
- You place your bet and receive two cards face up.
- The dealer takes two cards, one up and one down.
- You act first: hit (take a card), stand (keep your total), double (double your bet for one final card) or split (if you have a pair, play two hands).
- The dealer then reveals and must draw to a fixed rule – usually hit until 17 or more.
- Totals are compared; closest to 21 without busting wins.
Your four moves
- Hit – take another card. Do this on low totals where busting is unlikely.
- Stand – take no more cards. Do this on strong totals, or when the dealer is likely to bust.
- Double down – double your stake and take exactly one more card. Best on 10 or 11 against a weak dealer up-card.
- Split – turn a pair into two hands. Always split aces and 8s; never split 10s or 5s.
Basic strategy in a nutshell
Basic strategy is the proven best move for every hand against every dealer up-card. The full version is a chart, but these rules capture most of the value:
- Always split aces and 8s; never split 10s or 5s.
- Double on 11, and on 10 unless the dealer shows a 10 or ace.
- Stand on hard 17 or more, always.
- Stand on hard 12–16 when the dealer shows 2–6 (let them bust); hit when the dealer shows 7 or higher.
- Always hit a hard total of 8 or less.
- Never take insurance.
Playing a live-dealer or RNG game lets you keep a strategy chart open beside you – there is no shame in it, and it is the single fastest way to cut the house edge.
A practical basic-strategy table
The correct chart changes slightly with the number of decks and whether the dealer hits soft 17. This simplified table fits a common multi-deck game where the dealer stands on soft 17 and doubling after a split is allowed:
| Your hand | Dealer shows 2–6 | Dealer shows 7–A |
|---|---|---|
| Hard 8 or less | Hit | Hit |
| Hard 9 | Double against 3–6; otherwise hit | Hit |
| Hard 10 | Double against 2–9 | Hit against 10 or A |
| Hard 11 | Usually double | Check chart against A; otherwise double |
| Hard 12 | Stand against 4–6; otherwise hit | Hit |
| Hard 13–16 | Stand | Hit |
| Hard 17+ | Stand | Stand |
| Soft 13–17 | Double in selected weak-dealer spots; otherwise hit | Hit |
| Soft 18 | Double against 3–6, stand against 2/7/8 | Hit against 9/10/A |
| Soft 19+ | Stand | Stand |
Use a chart matched to the actual table rules for exact decisions. “Hard 16 against dealer 10” is a classic uncomfortable hit, but surrender may be better when the table offers it. The purpose of basic strategy is not to win every hand; it is to choose the action with the smallest expected loss across all possible dealer outcomes.
Pair splitting without guesswork
Pairs create some of the most expensive mistakes because the decision changes both the number of hands and the amount at risk.
| Pair | Usual basic-strategy action |
|---|---|
| Aces | Always split |
| 10s | Never split; 20 is already excellent |
| 9s | Split against 2–6 and 8–9; stand against 7, 10 or A |
| 8s | Always split |
| 7s | Split against 2–7; otherwise hit |
| 6s | Split against 2–6 when doubling after split is allowed |
| 5s | Never split; play the hand as hard 10 |
| 4s | Split only in limited doubling-friendly spots |
| 2s or 3s | Split against weak dealer cards when rules allow |
Splitting aces creates two chances to start with 11; splitting 8s turns a poor hard 16 into two playable hands. Splitting 10s sacrifices a strong 20 for two uncertain hands, which is why it is a bad trade even when it occasionally produces a dramatic result.
Table rules that change the house edge
Before sitting down, open the information panel and check more than the game title:
- Blackjack pays 3:2. A A$10 blackjack returns A$15 profit. At 6:5 it returns only A$12, a major reduction.
- Dealer stands on soft 17. If the dealer hits soft 17, the house edge generally rises by about 0.2 percentage points.
- Double after split is allowed. This preserves valuable doubling opportunities on the new hands.
- Late surrender is available. Surrendering selected weak hands can reduce the edge when used correctly.
- Resplitting aces and multiple splits. More flexible split rules are generally better for the player.
- Number of decks. Fewer decks can help, but only when the other rules remain favourable.
A table advertised as “classic blackjack” may still use 6:5 payouts or restrictive doubling. The information panel and paytable determine the value, not the visual theme.
What the payouts look like in A$
With a A$10 initial stake:
| Outcome | Balance change |
|---|---|
| Standard win | +A$10 |
| 3:2 blackjack | +A$15 |
| 6:5 blackjack | +A$12 |
| Push | A$0; stake returned |
| Double-down win | +A$20 after adding another A$10 |
| Insurance win | Pays 2:1 on the separate insurance stake |
Insurance is offered when the dealer shows an ace. It does not protect the original hand; it bets that the hidden card completes a blackjack. Unless you have advanced information about deck composition, the wager carries a high edge and basic strategy declines it.
RNG, live dealer and side bets
RNG blackjack deals quickly and normally allows low stakes, making it useful for learning with a strategy chart. Live-dealer blackjack is slower and shows real cards on camera, but table limits and rule variations can be less flexible. The mathematical comparison still starts with 3:2 versus 6:5, dealer soft-17 rules and doubling options.
Side bets such as Perfect Pairs or 21+3 are separate games layered onto the hand. Their large top payouts usually come with a much higher house edge than the main blackjack bet. If value is the goal, skip them.
Managing a blackjack session
Basic strategy reduces the edge; it does not remove variance. Doubles and splits can require extra stakes, so a A$10 table can demand A$30 or A$40 during one initial hand. Choose a base bet that leaves room for those correct decisions instead of being forced to avoid them because the balance is too small.
Set a session limit in A$ and time, keep the base stake stable and never raise it to chase a losing run. Card counting is not a practical strategy in reshuffled RNG games and is usually neutralised by continuous shuffling in live games.
Mistakes that cost you money
The three big leaks are taking insurance, standing on low totals against a strong dealer card out of fear, and playing 6:5 blackjack tables instead of 3:2. The last rule commonly adds about 1.4 percentage points to the house edge, so always check the payout before you sit down.
Blackjack in one line
Beat the dealer by getting closer to 21 without busting, follow basic strategy for every hand, skip insurance and 6:5 tables, and you will be playing at roughly a 0.5% house edge – the best value a casino offers. If gambling stops being fun, call Gambling Help Online on 1800 858 858.
