Before you sit down
You are standing behind a blackjack table with a stack of chips in your hand, and the first thing you need to know is not a strategy chart. It is what the little printed panel on the felt says. That panel states the exact rule set in force at that table: how many decks are in the shoe, whether the dealer stands or hits on a soft 17, what you may double, and whether you may surrender. Every decision you make after you sit down is filtered through those rules. Two tables in the same venue can play differently, and a published strategy chart only matches one specific rule set.
Blackjack is a comparing card game. Your objective is to finish the round with a hand total closer to 21 than the dealer's, without your total exceeding 21. You do not play against the other people at the table; their hands have no effect on yours. You play only against the dealer's hand, under the constraints the dealer must follow.
Buying in and placing a bet
You buy chips at the table, not at the cage, in most venues. Place your cash on the felt in front of you rather than handing it to the dealer; the dealer spreads it, announces the amount, and pushes chips back to you. Once you have chips, you place a wager in the betting circle printed in front of your seat before any cards are dealt. The table will show a minimum and maximum bet for that seat.
The dealer then deals each player two cards and takes two for the house. In the most common format, your cards are dealt face up and the dealer takes one card face up and one face down, the hole card. In some regions or older formats, your cards are dealt face down and you handle them yourself. The face-up format is the one you will most often encounter, and it changes nothing about the decisions; it only changes how the cards are handled on the felt.
Card values and the running total
Numbered cards count as their printed value. Face cards count as ten. An ace counts as one or eleven, whichever gives you the better total without exceeding 21. A hand containing an ace counted as eleven is called a soft hand, because the ace can drop to one if you draw a card that would otherwise bust the hand. A hand without an ace, or with an ace forced to count as one, is a hard hand.
Your two starting cards determine the first decision you face. If they total 21, you have a blackjack, sometimes called a natural. That hand is settled immediately unless the dealer also shows a possible natural, and it pays at a higher rate than a normal win under most rule sets. The exact payout is printed on the table; it is commonly stated as a ratio rather than a percentage.
The sequence of a round
Play moves around the table from the dealer's left. On your turn you announce your decision by hand signal even when your cards are face up, because the cameras above the table record signals, not words. The decisions available to you are:
- Stand: take no more cards and lock in your total.
- Hit: take one additional card. You may hit again until you stand or your total exceeds 21.
- Double down: add a second wager equal to your first, up to the table maximum, and receive exactly one more card. Some tables restrict doubling to certain starting totals.
- Split: if your first two cards are a pair, you may separate them into two hands, each with its own wager equal to your original bet, and play each hand independently. Some tables allow re-splitting and some do not.
- Surrender: where offered, you may forfeit half your wager and end the hand before playing it out. Some tables offer late surrender only, meaning you may use it after the dealer checks for a natural.
When every player has acted, the dealer reveals the hole card and plays the house hand according to a fixed rule printed on the table. The dealer does not choose. The most common rule is that the dealer must hit any total of 16 or lower and stand on any total of 17 or higher, with a separate printed note stating whether a soft 17 is hit or stood on. That single rule changes the house edge on the game and changes what your own correct decisions are.
How a hand settles
If your total exceeds 21, you lose your wager immediately, even if the dealer later busts. If the dealer's total exceeds 21, every player hand still in the round wins. If neither side busts, the higher total wins. Equal totals push, and your wager is returned. A player blackjack beats a dealer total of 21 made from three or more cards, but pushes against a dealer blackjack under most rule sets.
Winning bets are paid at even money, meaning you receive your original wager back plus an equal amount, unless the hand is a blackjack. The blackjack payout is printed on the felt and is commonly higher than even money, though the exact ratio varies by table.
Where the house edge sits
Blackjack is unusual among table games because your decisions change the expected loss on the hand. The house advantage is not a single fixed number that applies to everyone at the table. A player who stands on every hand, or who hits every hand, loses at a materially faster rate than a player who follows the decision rules that match the table's rule set. The edge also shifts with the rules themselves: the number of decks, the soft-17 rule, doubling restrictions, split restrictions, and the blackjack payout each move the expected loss by a measurable amount.
| What changes | How it changes the house edge | What stays fixed |
|---|---|---|
| Dealer hits soft 17 instead of standing | Increases the house edge on the game | The dealer's action is fixed by table rule, not choice |
| Fewer decks in the shoe | Generally lowers the house edge, all else equal | Card values and the 21 target do not change |
| Restricted doubling or splitting | Increases the house edge by removing player options | Your objective stays the same |
| Lower blackjack payout ratio | Increases the house edge, because the best hand pays less | A natural still beats a three-card 21 |
| Your own decisions | Move your personal expected loss up or down within the table's range | The table's rule set is unchanged by how you play |
No decision removes the house edge. A correct basic-strategy play is the one that minimises expected loss on that hand under the specific rules printed at the table, not a move that guarantees a win. The long-run average is built from a very large number of hands, and any single session can end far above or far below it.
Reading a strategy chart correctly
Published basic-strategy charts are grids that tell you the correct action for your hand total against the dealer's upcard. They are derived by calculation from one exact rule set. A chart built for a six-deck shoe where the dealer stands on soft 17 and doubling after splitting is allowed will not be correct at a table with a single deck, a hit-on-soft-17 rule, or no doubling after splits. Before you use a chart, check the rule assumptions printed on it against the panel on the felt. If they differ, the chart is not the right tool for that table.
Strategy charts are not a way to beat the game. They are a way to avoid giving away more than the table rules already take. A player who deviates from the chart is not unlucky; they are making a decision with a worse expected loss than the alternative.
Procedural mistakes that cost new players
The first mistake is touching the cards when they are dealt face up. In that format you never touch the cards; you signal your decision with your hand. Touching the cards will draw an immediate correction from the dealer and can void a hand. The second is touching your wager after the deal begins. Once cards are out, the bet belongs to the round; adjusting it is treated as an attempt to change the wager after seeing the cards. The third is announcing a decision verbally instead of signalling. The camera record is the signal, and a spoken word that does not match your hand movement can create a dispute that resolves against you. The fourth is sitting down with a strategy chart that does not match the table's printed rules, which converts a careful player into a careless one without any visible sign at the table.
If you are unsure of the signal for a decision, ask the dealer before the round starts. Dealers will show you the hand motion for hit, stand, double and split. Asking between rounds costs nothing; asking after a card has been dealt can cost you the hand.
FAQ
Does the order of players at the table change my odds?
No. Your hand is compared only with the dealer's hand. The cards other players take or leave do not change the mathematical position of your hand, though they can change which cards the dealer draws next. That effect is random and does not favour any seat.
Is a soft 17 the same as a hard 17?
No. A soft 17 contains an ace counted as eleven, such as ace-six, so it can be hit without busting. A hard 17 has no ace or an ace counted as one. Whether the dealer hits or stands on soft 17 is a printed table rule, and it changes the house edge.
Can I use a strategy chart at the table?
Most venues permit a printed chart at the table, but it must match the rule set in force. Check the chart's stated assumptions against the panel on the felt before you rely on it. A chart for the wrong rule set is worse than no chart at all.
