Blackjack rules are some of the simplest in the casino. You and the dealer chase the same number: 21. Get closer without going over, and you win. This guide breaks down the official rules of blackjack online, from card values to payouts, so you can sit down at any table and play with confidence.
The Objective of Blackjack and How Cards Are Valued
The goal never changes. Beat the dealer’s hand without your total going over 21. Hands are scored using simple card values, and every blackjack rule that follows builds on this one idea.
Cards 2 through 9 count at face value. Face cards, Jack, Queen, and King, are worth 10 points each. The Ace flexes between 1 and 11, whichever number serves your hand better.
Two cards that total 21 on the deal is a natural blackjack, and it’s the strongest hand in the game. Most online blackjack rules pay this hand at 3:2, meaning a $10 bet returns $15 in winnings. Hold that figure in your head. It matters later when we get to payout rules.
- An Ace plus a 10-value card on the deal is blackjack, not 21 built from three cards.
- A hand with an Ace counted as 11 is called soft, like soft 17 or soft 18. Once that Ace drops to a value of 1, the hand turns hard.
- Suits carry no weight in blackjack. Only rank matters.
How a Hand of Online Blackjack Is Dealt
Every round starts the same way. You place your bet, then the cards land.
You receive two cards face up. The dealer receives two cards as well, but one stays face down, the hole card, until the hand finishes. That single hidden card is what makes blackjack rules around insurance and dealer blackjack checks necessary; more on that shortly.
From there, you choose how to play your hand. Hit asks for another card. Stand locks in your total and ends your turn. Bust means your total cleared 21, and the hand is over regardless of what the dealer holds. A push happens when your total ties the dealer’s, and your bet comes back to you untouched.
Decks vary by blackjack variant, running anywhere from a single deck up to eight decks shuffled together in a shoe. More decks generally nudge the house edge up slightly, which is why single deck and double deck games tend to attract sharper players.
Blackjack Dealer Rules: Why the House Plays Last, and Why It Matters
Dealer play is not optional, and that is the part most new players miss. You get to choose your moves. The dealer does not.
House rules force the dealer to hit on any total of 16 or below. Once the dealer reaches 17, they stand, full stop. This single blackjack rule shapes almost every basic strategy decision you will ever make.
Soft 17 adds a wrinkle. Some tables require the dealer to stand on a soft 17, an Ace plus a 6, which favours you. Others force a hit on soft 17, which favours the house by roughly 0.2%. Check the felt or the game info screen before you sit down. It tells you which rule is in play.
Dealers do not have the freedom to double, split, or take insurance for themselves. Their hand plays out mechanically every single time.
Splitting and Doubling Down: Blackjack Rules for Building a Better Hand
Two more options open up once you see your first two cards, and both can tilt the odds back toward you when used correctly.
Splitting is allowed when your first two cards share the same rank, like two 8s or two Jacks. Split them into two separate hands, match your original bet on the second hand, and play each one out against the dealer independently. A pair of Aces is the one split most basic strategy charts insist on every single time.
Doubling down doubles your original bet in exchange for exactly one more card. Most casinos allow it on any first two cards, though some restrict it to specific totals. Doubling after a split, taking that option on a hand that came from splitting, is a player-friendly rule when it’s offered, since it adds another opportunity to capitalise on a strong hand.
Move | What It Does | Best Used When |
Split | Breaks a pair into two separate hands | You hold 8s, 9s, or Aces |
Double Down | Doubles your bet for exactly one card | Your total is 9, 10, or 11 |
Hit | Takes another card | Your total sits below 17 |
Stand | Ends your turn | Your total is 17 or higher |

The Blackjack Insurance Rule Explained
Insurance only shows up when the dealer’s face-up card is an Ace, and it works like a side bet on a single outcome.
You can wager up to half your original bet that the dealer’s hidden card is worth 10. Guess right, and insurance pays 2:1. Guess wrong, and you lose the side bet outright, separate from whatever happens with your main hand.
Here’s the catch. In a standard six-deck shoe, only about 4 cards in 13 are worth 10. The math behind insurance rarely favours you unless you’re tracking the deck through card counting, and even then the edge is thin. Basic strategy says skip it, almost every time.
If you want to understand why card counters treat insurance differently from everyone else, the card counting guide covers the deck-tracking logic in full.
Blackjack Payout Rules: 3:2 vs 6:5
Payout structure is the blackjack rule that affects your bankroll more than any other, and it hides in plain sight on the table felt.
A 3:2 payout returns $3 for every $2 wagered on a natural blackjack. A 6:5 table returns less, just $6 for every $5 wagered, on the same winning hand. That gap sounds small until you run the numbers over a full session.
Payout | $20 Blackjack Bet Returns | Player-Friendly? |
3:2 | $30 | Yes, the standard fair rule |
6:5 | $24 | No, raises the house edge by over 1% |
Always check the payout odds before your first hand. A 6:5 table can look identical to a 3:2 table from across the room, but the difference adds up fast. Real money blackjack tables worth your bankroll will display 3:2 payouts clearly in the game rules.
Blackjack Surrender Rules
Surrender lets you forfeit half your bet and walk away from a hand before it plays out, and it’s one of the rarer rules you’ll find at the table.
Late surrender, the more common version, only becomes available after the dealer checks for a natural blackjack. Early surrender, by contrast, lets you fold before that check happens, and it’s tougher to find online.
Surrender earns its keep on a narrow set of hands, hard 15 or 16 against a dealer’s strong upcard being the classic example. Used outside those spots, it just gives away equity you didn’t need to give up.

Online Blackjack Rules by Variant
Standard blackjack rules shift slightly depending on which variant you sit down at, and knowing the differences helps you pick the table that suits your bankroll.
- Classic Blackjack sticks closest to the traditional rule set, usually dealt from one to eight decks.
- European Blackjack deals the dealer just one face-up card at first, with no hole card until after your turn.
- Atlantic City Blackjack runs eight decks with player-friendly rules, including double down on any two cards.
- Spanish 21 strips all 10s from the deck but compensates with liberal doubling and bonus payouts on certain 21s.
- Double Exposure Blackjack shows both dealer cards face up, then balances it out with tougher push rules.
- Super Fun 21 adds late surrender on any hand and a player blackjack that beats the dealer outright.

Blackjack Rules FAQ
What are the basic rules of blackjack?
Beat the dealer’s hand without going over 21. Number cards count at face value, face cards count as 10, and an Ace counts as 1 or 11. You can hit, stand, double down, or split depending on your hand, while the dealer must hit until reaching 17.
Does blackjack pay 3 to 2 or 6 to 5?
It depends on the table. A 3:2 payout is the standard, fair blackjack rule and returns $15 on a $10 bet. A 6:5 payout returns only $12 on the same bet and raises the house edge by more than 1%. Always check the felt before you play.
What is the dealer’s rule for hitting in blackjack?
The dealer must hit on any total of 16 or below and stand once reaching 17. Whether the dealer hits or stands on a soft 17 depends on the specific table rules, usually printed on the felt or listed in the game info.
Is taking insurance a good bet in blackjack?
Not usually. Insurance pays 2:1 if the dealer has blackjack, but the odds of that happening are normally worse than the payout suggests. Basic strategy recommends skipping insurance unless you’re counting cards.
Can you double down after splitting in blackjack?
It depends on the casino. Some tables allow doubling down on a hand that came from a split, which lowers the house edge slightly. Check the table rules before you split, since not every variant offers this option.
What happens when you tie with the dealer in blackjack?
It’s called a push. Your hand and the dealer’s hand total the same number, and your original bet is returned to you in full. Nobody wins or loses on a push.
