Blackjack has a reputation as the thinking person's casino game, and part of that reputation is earned: the player makes genuine decisions on every hand. Those decisions shape how much the game costs, but they never hand the advantage to the player. This guide covers the rules, the layout of the table and the small courtesies that make a first visit easier. Everything here is aimed at grown-up players.
The goal in one sentence
You are not playing against the other people at the table. Each seat plays its own hand against the dealer, and the aim is to finish with a total closer to 21 than the dealer's without going over. Go past 21 and the hand is "bust", which loses on the spot, even if the dealer later busts too. That single rule, with the player acting first and losing first, is where the casino's advantage comes from.
What the cards are worth
| Card | Value |
|---|---|
| 2 to 10 | Face value |
| Jack, queen, king | 10 each |
| Ace | 1 or 11, whichever suits the hand |
A hand in which an ace counts as 11 is called soft, because the next card cannot bust it: an ace and a 6 make a soft 17. A hand without that cushion is hard. An ace plus any ten-value card as the first two cards is a blackjack, the best hand in the game.
How a round unfolds
- Bets go down. Each player places chips in the betting circle before any card is dealt.
- The deal. Everyone, the dealer included, receives two cards. One of the dealer's cards is face up; the other, the hole card, stays hidden.
- Player decisions. Starting from the dealer's left, each player completes their hand in turn.
- The dealer's turn. The dealer turns over the hole card and draws according to fixed house rules, with no choices of their own.
- Settlement. The higher total wins; equal totals are a push and the bet is handed back.
Your options on each hand
- Hit: take another card. You can keep hitting until you stand or bust.
- Stand: keep the total you have.
- Double down: double the bet in exchange for exactly one more card. Most tables allow it on the first two cards only.
- Split: if the first two cards share a rank, add a second equal bet and play them as two separate hands.
- Surrender: where the table offers it, give up the hand straight after the deal and get half the stake back.
The dealer has no choices
The dealer must draw on 16 or less and stand on 17 or more. The one common variation is soft 17: some tables make the dealer stand on it, others make the dealer hit. The rule is usually printed on the felt, and the version where the dealer stands is slightly kinder to players.
Payouts and the house edge
An ordinary winning hand pays even money. A natural blackjack traditionally pays 3 to 2, so a 10 bet earns 15 in winnings. Many tables now pay only 6 to 5 on a blackjack, which looks similar on paper but takes noticeably more from the player over time; it is one of the first things worth checking before you sit down.
The house edge is the share of each bet the casino expects to keep on average across a very large number of hands. In blackjack it depends on the rules in force and on how well the player decides. With favourable rules, a 3 to 2 payout and decisions made by the book, the edge is commonly given as roughly half a percent. Playing on hunches or sitting at a 6 to 5 table pushes it well above that. Either way it stays on the casino's side; the decisions only change how big the slice is. Our companion piece on blackjack basic strategy explains where those by-the-book decisions come from.
A word about insurance
When the dealer shows an ace, you will be offered insurance: a side bet of up to half your stake that pays 2 to 1 if the dealer has blackjack. It sounds protective, but it is a separate wager priced worse than the main game, and most guides advise ordinary players to turn it down.
Etiquette at a live table
- Lay cash on the felt when buying in; dealers do not take money from your hand.
- Use hand signals as well as words: tap the table to hit, wave a flat hand over the cards to stand. The cameras above the table need to see each decision.
- In games dealt face up from a shoe, leave the cards where they lie. In hand-held games, touch them with one hand only.
- Once the cards are out, leave your chips alone until the hand is settled.
- Other players' choices do not change your expected result over time, so there is no need to comment on how anyone else plays.
Online and live-dealer versions handle most of this with buttons, but the rules shown on the screen deserve the same careful reading as a printed felt.
Before you play
Blackjack is entertainment with a price, not a way to make money, and no system or betting pattern changes that. Decide your budget and your stopping time before the first hand, and check the rules where you live, since the legal age and the status of online casinos differ from one country to the next.
