The moment the cards are dealt
You have bought in, placed a wager in the betting circle, and the dealer is moving around the table. Each player gets two cards face up, and the dealer takes one card up and one card down. That down card, the hole card, changes what you can see but not what you are trying to do. The objective is a hand total closer to 21 than the dealer's, without going over 21. Aces count as either 1 or 11, whichever helps the hand; tens and face cards count as 10; every other card counts as its printed value.
What confuses new players is that you are not trying to beat the other people at the table. You are playing against the dealer's hand alone. The other players' cards only matter because they consume cards from the shoe and because their decisions change the pace of the game. Your hand stands or falls on its own total against the dealer's total.
Buying in and placing a bet
You cannot hand cash to the dealer and expect it to become a bet. The correct sequence is to place your money on the table, not into the dealer's hand, and wait. The dealer spreads the cash on the layout, calls out the amount, and a supervisor verifies it. Only then do chips come back to you. This is a security measure, not a formality: it creates a witnessed record of how much you bought in for.
Once you have chips, you put a wager in the betting circle in front of your seat before the first card is dealt. The table will carry a printed minimum and maximum for that seat. If you are unsure what the minimum is, look at the small sign on the table or ask the dealer before the hand begins. Once the first card leaves the shoe, you cannot add to or remove from the wager except through the specific doubling or splitting rules described below.
The sequence of a hand
After the initial two cards, play moves from the dealer's left to right. At your turn you have a set of decisions, and each one changes the hand in a specific way.
Stand means you are satisfied with your total and take no more cards. Wave your hand palm-down over your cards to signal it. Hit means you want another card, and you may keep hitting until you stand or your total exceeds 21, at which point the hand is dead and the dealer collects your wager immediately. Double down lets you add a second wager equal to your first and receive exactly one more card, after which your hand stands automatically. Split is available when your first two cards are a pair: you place a second wager equal to the first, the dealer separates the cards into two hands, and you play each one in turn. Some tables allow re-splitting and some do not; some allow doubling after a split and some do not. Surrender, where offered, lets you forfeit half your wager and end the hand before playing it out.
When every player has finished, the dealer reveals the hole card and plays according to a fixed rule printed on the table. The most common rule is that the dealer must hit on any total of 16 or lower and stand on any total of 17 or higher. Some tables require the dealer to hit a soft 17, a hand containing an ace counted as 11. That one rule changes the house edge on the whole table, which is why strategy charts are written for a specific rule set rather than for blackjack in general.
How the settlement works
If your total exceeds 21, you lose the wager no matter what the dealer does later. If the dealer exceeds 21, every remaining hand wins. If neither side busts, the higher total wins. Equal totals push, meaning your wager is returned with no win and no loss.
A winning hand is paid at even money: one unit of profit for each unit wagered. The exception is a blackjack, an ace plus a ten-value card on the first two cards. A blackjack is paid at 3 to 2 at most tables, meaning a 10-unit wager returns 15 units of profit. Some tables pay 6 to 5 instead, which is a materially worse return on the same hand. The payout ratio is printed on the table felt, and it is worth reading before you sit down, because nothing else about the hand changes but the amount you receive for the best possible result does.
Insurance is offered when the dealer's up card is an ace. You may wager up to half your original bet that the dealer's hole card is a ten-value card, giving the dealer a blackjack. If the dealer has it, the insurance bet pays 2 to 1 and your original wager loses unless you also have a blackjack, which pushes. If the dealer does not have it, the insurance wager is collected and the hand continues.
Where the edge sits on each bet
Blackjack is unusual among table games because the decisions you make change the expected rate of loss on the hand. The house edge on the main game depends on the table's rule set and on how closely your decisions match the basic strategy for that rule set. Basic strategy is a published set of plays, one for every possible player total against every possible dealer up card, derived from the exact rules in use. A chart written for a six-deck game where the dealer stands on soft 17 is not correct for a double-deck game where the dealer hits soft 17.
The side bets are a different proposition. They resolve independently of the main hand and carry their own, generally larger, house edges. The table below compares the main bet types you will encounter.
| Bet | What it pays | What drives the house edge | Player decision involved |
|---|---|---|---|
| Main hand | Even money; 3 to 2 or 6 to 5 on a blackjack | Table rule set and how closely play matches basic strategy for that set | Yes, every hand |
| Insurance | 2 to 1 if the dealer has blackjack | The proportion of ten-value cards remaining against the payout offered | Only when dealer shows an ace |
| Side bets (e.g. pairs, suited runs) | Varies by table, printed on the layout | The specific pay table, typically a larger edge than the main hand | Optional, before the hand |
None of these bets is a way to win in the long run. The main hand, played to the correct basic strategy for the table's rules, carries a smaller expected loss per unit wagered than the side bets generally do. That is a statement about the rate at which a bankroll is consumed, not a promise that any session ends ahead.
What changes from table to table
Blackjack is not one game with one set of numbers. The things that vary between tables are exactly the things that change the house edge, and they are all printed or visible before you play.
- The blackjack payout: 3 to 2 or 6 to 5.
- The number of decks in the shoe.
- Whether the dealer stands or hits on soft 17.
- Whether doubling after a split is allowed.
- Whether re-splitting is allowed, and how many times.
- Whether surrender is offered.
- Which side bets are available and what their pay tables are.
Each of these is a rule, not a decoration. A player who learns basic strategy for one table and then sits at another with different rules is playing a slightly different game. The correct move is to find the chart that matches the table in front of you, or to ask the dealer to confirm the rule before you commit to a decision that depends on it.
Procedural mistakes that cost money
The first mistake is touching the cards. In most shoe-dealt games, the cards stay on the felt and you signal your decisions with hand gestures. Reaching for the cards will get you a warning, and repeated contact can get you removed from the table, because the casino cannot verify that cards have not been marked or switched.
The second is touching your wager after the hand starts. Once the first card is dealt, the bet in the circle belongs to the hand. Players who try to add chips after seeing a good first card, or pull chips back after a bad one, are attempting to change a wager that is already live. The dealer will stop it, and the attempt is recorded.
The third is taking insurance as a habit. Insurance is a separate bet on the dealer's hole card, and it carries its own edge. Taking it on every ace turns a decision that is occasionally defensible under a specific counting method into a steady additional cost. New players take it because they think of it as protecting the hand; mechanically, it is a side wager that the dealer has a ten underneath, and it is settled on its own terms.
What a strategy chart is and is not
A basic strategy chart is a lookup table. For each player total and each dealer up card, it tells you the play that minimises expected loss under the rule set it was built for. It does not tell you what will happen on the next hand. It does not guarantee a win, and it does not overcome the house edge entirely; it reduces the rate at which that edge applies to your play.
Charts are published for specific rule combinations, and the differences are not cosmetic. A hand like 11 against a dealer 10 is a double down under most rule sets, but the correct play on a soft 18 against a dealer 6 changes depending on whether doubling after a split is allowed and whether the dealer hits soft 17. If you carry a chart, make sure it names the deck count, the dealer's soft-17 rule, and the doubling and splitting rules it assumes. If the table in front of you differs on any of those, the chart is not authoritative for that table.
FAQ
Do you pay the dealer or the table when you buy in?
You place cash on the table in front of you, never into the dealer's hand. The dealer spreads it on the layout, announces the amount, and a supervisor confirms it before chips are pushed to you. This is the standard procedure at a table game and exists so that every buy-in has a witnessed record.
Can you change your bet after seeing your first card?
No. Once the first card is dealt, the wager in the betting circle is live and cannot be increased or reduced except through the specific doubling or splitting rules that apply to that hand. Attempting to touch or adjust the wager mid-hand will be stopped by the dealer.
Why do two blackjack tables pay different amounts for the same hand?
Because the blackjack payout is a table rule, not a universal constant. One table may pay 3 to 2 on a blackjack while another pays 6 to 5, and the difference is printed on the felt. The 6 to 5 payout returns less on the best hand in the game, so it is worth checking before you sit down.
