The Basics

What is the Goal of Blackjack?

The goal of Blackjack is simple: beat the dealer's hand without going over 21. Going over 21 is called a bust — and a busted hand automatically loses, regardless of what the dealer holds.

You are not playing against other players at the table. Each hand is a separate battle between you and the dealer.

🂡
WIN
Your hand is closer to 21 than the dealer's without busting — or the dealer busts. Pays 1:1. Natural Blackjack pays 3:2.
🤝
PUSH
Your hand total equals the dealer's total. Bet is returned — no gain, no loss.
❌
LOSE
Your hand is lower than the dealer's, or you bust. You lose your bet.
👑
Best odds in the casino: With basic strategy, Blackjack's house edge drops to approximately 0.5% — lower than Baccarat (1.06%), Roulette (2.7%), and dramatically lower than Slots. No other mass-market casino game rewards player skill this directly.

Fundamentals

Card Values in Blackjack

Every card in the deck has a point value. Suits (♠♥♦♣) are irrelevant — only the rank matters.

2–9
Face Value
A 7 is worth 7 points. A 3 is worth 3 points.
10
10 points
The 10 card is worth exactly 10.
J Q K
10 points each
Jack, Queen and King — all worth 10. The most common card value in the deck.
A
1 or 11
The Ace is worth 11 unless that would cause a bust — then it counts as 1.
🂡
Hard vs Soft hands: A hand with an Ace counted as 11 is called a Soft hand (e.g. Ace-6 = Soft 17). A hand with no Ace, or where the Ace must count as 1 to avoid busting, is a Hard hand (e.g. 10-7 = Hard 17, or Ace-6-10 = Hard 17). Soft hands cannot bust on a single hit — this changes your strategy significantly.

What is a Natural Blackjack?

A Natural Blackjack — also called simply "Blackjack" or "a natural" — is an Ace plus any 10-value card (10, J, Q, or K) dealt as your first two cards. This is the best possible hand and pays 3:2 (so a 10-coin bet returns 25 coins). If both you and the dealer have Blackjack, it's a Push.

⚠️
Avoid 6:5 tables: Some Blackjack tables pay only 6:5 on a natural Blackjack instead of the standard 3:2. On a 10-coin bet, 6:5 pays only 12 coins instead of 15. This single rule change more than doubles the house edge, from ~0.5% to over 1.4%. Always look for 3:2 Blackjack.

Step by Step

How to Play Blackjack — Round by Round

1
Place Your Bet
Before any cards are dealt, place your chips in the betting area. This is your main bet. Optional side bets (like Perfect Pairs) are placed separately.
2
Cards Are Dealt
You receive two cards face up. The dealer receives two cards — one face up (the upcard) and one face down (the hole card). Your strategy always reacts to the dealer's visible upcard.
3
Check for Blackjack
If you have a natural Blackjack (Ace + 10-value card) and the dealer doesn't, you win immediately at 3:2. If both have Blackjack it's a Push. If only the dealer has Blackjack, you lose (unless you took Insurance).
4
Choose Your Action
If no immediate Blackjack, you act on your hand: Hit, Stand, Double Down, Split, or Surrender. You continue taking actions until you Stand or bust. Then the dealer plays.
5
Dealer Plays
The dealer reveals the hole card and must follow fixed rules: Hit on 16 or less, Stand on 17 or more. The dealer has no choice — they cannot Double, Split, or Surrender. If the dealer busts, all remaining player hands win.
6
Hands Are Compared
The dealer's final total is compared against yours. Closest to 21 without busting wins. Equal totals Push. Winning hands are paid 1:1 (or 3:2 for Blackjack).

Player Actions

Hit, Stand, Double, Split & Surrender

Once you're dealt your two cards, you have up to five actions available depending on the situation. Knowing when to use each one is the heart of Blackjack strategy.

H — Action
Hit
Take one more card. You can Hit as many times as you like. If your total exceeds 21, you bust and lose immediately. Available on any hand.
S — Action
Stand
Keep your current hand and end your turn. No more cards are drawn. The dealer then plays their hand. Available on any hand.
D — Action
Double Down
Double your bet and receive exactly one more card, then automatically Stand. Only available on the first two cards (before hitting). High-value move when the dealer is weak.
P — Action
Split
If your first two cards are a pair, split them into two separate hands, each with its own bet equal to your original wager. You then play each hand independently. Available on any pair.
SR — Action
Surrender
Fold your hand and recover half your bet. Surrender is only available on your first two cards (before any other action). Use only when basic strategy says it's the best option.
Side Bet
Insurance
Offered when the dealer shows an Ace. A side bet worth half your original wager that pays 2:1 if the dealer has Blackjack. House edge ~7% — always decline.
🃏
Split rules for Aces: When you split Aces, most casinos deal only one card to each Ace — you cannot Hit further. Additionally, a 10-value card on a split Ace pays 1:1 (not 3:2) because it is not considered a natural Blackjack.

Bets & Payouts

Blackjack Payouts & House Edge

House edge comparison: Blackjack (basic strategy) ~0.5%  ·  Baccarat Banker ~1.06%  ·  European Roulette ~2.7%  ·  Craps Pass Line ~1.41%  ·  Slots 2–15%. Only video poker (Jacks or Better) rivals Blackjack for pure value — but Blackjack requires zero memorisation to get a significant edge.

Key Probability

Dealer Bust Rates by Upcard

Everything in Blackjack strategy flows from one insight: the dealer's upcard determines how likely they are to bust. Weak upcards (2–6) bust more often — that's why you Double and Stand more when the dealer is weak. Strong upcards (7–Ace) bust rarely — that's why you Hit more aggressively against them.

The Strategy Chart

Basic Strategy — The Optimal Move for Every Hand

Basic strategy is the mathematically correct decision for every combination of your hand and the dealer's upcard, computed from billions of simulated hands. Using perfect basic strategy brings the house edge down to approximately 0.5%. Any deviation increases the house edge.

Find your hand total on the left. Find the dealer's upcard along the top. The cell where they intersect tells you the optimal action.

H = Hit
S = Stand
D = Double (Hit if not allowed)
Ds = Double (Stand if not allowed)
P = Split
SR = Surrender (Hit if not allowed)

💡
The three rules everyone should know: (1) Always split Aces and 8s — two separate hands from a terrible hard 16 is always better. (2) Never split 10s — a 20 is already a near-certain win, don't break it. (3) Never split 5s — treat them as Hard 10 and Double instead.

Expert Tips

Blackjack Strategy Tips

1
Learn basic strategy first — it's worth more than any "system"
No betting system (Martingale, Fibonacci, etc.) changes the house edge. Basic strategy does. Memorising the chart takes an hour; the return is a lifetime of better play. Royal Blackjack is a perfect free environment to practise until the decisions feel automatic.
2
Always assume the dealer's hole card is a 10
This heuristic works because 10-value cards (10, J, Q, K) make up roughly 31% of the deck — more than any other single value. Against a dealer 6, assume their total is 16 — they must hit and are very likely to bust (42%). Against a dealer 10, assume 20 — you need a strong hand or you're drawing.
3
Never take Insurance
Insurance pays 2:1 when the dealer has Blackjack, but 10-value cards make up only ~31% of the deck — not the 33.3% needed to break even. The house edge on Insurance is approximately 7%, making it one of the worst bets in the casino. Even Money (offered on your Blackjack vs dealer Ace) is the same bet — decline it.
4
Stand on Hard 12–16 when the dealer shows 4, 5, or 6
This is the move beginners get wrong most often. Against dealer 4–6, the dealer busts more than 40% of the time. Your job is not to take a risk — let the dealer bust. Standing on Hard 12 vs dealer 4 feels wrong but is mathematically correct.
5
Double Down aggressively on 9, 10 and 11
These are your best opportunities to maximise wins. Hard 11 against anything except an Ace should almost always be Doubled. Hard 10 against dealer 2–9. Don't be timid — basic strategy says Double, so Double.
6
Surrender Hard 16 vs dealer 9, 10, Ace — and Hard 15 vs dealer 10
Surrendering feels like giving up, but it's a mathematically proven save. When you surrender you recover half your bet. Against a dealer 10 with Hard 16, you lose more than 77% of hands — surrendering for a half-bet loss is strictly better than playing it out.
📊
Soft 17 rule matters: Some casinos make the dealer Hit on Soft 17 (H17) instead of standing. H17 increases the house edge by approximately 0.2%. Royal Blackjack uses Dealer Stands on Soft 17 (S17) — the more player-friendly rule.
