The Rule You Need to Read Before You Buy In
You sit down, buy chips, and the dealer starts dealing. Then you notice something: on one table the dealer stops at 17, and on the next table the dealer keeps hitting. You have not misread the game. Blackjack has two standard dealer rules, and the table you choose determines which one applies to every hand you play.
The dealer's standing number is either 17 or 18 depending on how the table treats a soft 17. A soft 17 is any hand totaling 17 that contains an ace counted as 11, such as ace-6. A hard 17 contains no ace counted as 11, or an ace counted as 1, such as 10-7. The two common rules are: the dealer stands on all 17s, or the dealer hits soft 17 and stands on hard 17 and any total of 18 or higher.
This rule is printed on the table felt or on a placard near the dealer, usually in small text that says "Dealer must stand on all 17s" or "Dealer hits soft 17." Read it before you play. It changes the house edge and the correct way to play certain hands.
Hard 17, Soft 17, and Why the Distinction Exists
A dealer's total is not just a number. The composition of the hand matters because an ace is flexible. When the dealer holds ace-6, the hand is 7 or 17. If the rule says stand on all 17s, the dealer stops at 17. If the rule says hit soft 17, the dealer takes another card because the ace can fall back to 1 and the hand cannot bust on that single hit.
The distinction exists because hitting a soft 17 gives the dealer a chance to improve to 18, 19, 20 or 21, while the ace protects against an immediate bust. The cost to the player is real but small. A dealer who hits soft 17 adds to the house edge compared with a dealer who stands on all 17s, because the dealer will occasionally turn a weak 17 into a stronger total.
| Dealer hand | Stand on all 17s | Hit soft 17 |
|---|---|---|
| Hard 17 (10-7, 9-8, no ace as 11) | Dealer stands | Dealer stands |
| Soft 17 (ace-6, ace-2-4) | Dealer stands | Dealer hits |
| 18 or higher | Dealer stands | Dealer stands |
| 16 or lower | Dealer hits | Dealer hits |
The table shows the only difference between the two common rules is the treatment of soft 17. Everything else about the dealer's play is identical: the dealer has no choices, no discretion, and no strategy. The dealer follows the printed rule on every hand.
How the Dealer's Rule Changes Your Decisions
The dealer's standing rule is not a background detail. It changes the correct play on several of your own hands because the dealer's chance of finishing with a strong total shifts. When the dealer hits soft 17, the dealer will bust slightly less often and make stronger hands slightly more often than when standing on all 17s.
Basic strategy charts are built for a specific rule set. A chart for a game where the dealer stands on all 17s is not necessarily correct for a game where the dealer hits soft 17, and the reverse is also true. The differences are small on any single hand, but they compound over many hands. Published basic-strategy charts derive from the exact rule set in use, including the number of decks, whether doubling after splitting is allowed, and whether the dealer stands or hits on soft 17.
If you use a chart, match it to the table. If you do not use a chart, understand that the dealer hitting soft 17 makes the game slightly worse for you and slightly changes the borderline decisions on hands like 11 against a dealer's ace, or soft 18 against a dealer's 2.
The Sequence of a Round, From Buy-In to Settlement
Knowing the dealer's standing rule is one part of sitting down correctly. The round itself follows a fixed order, and understanding that order prevents procedural mistakes.
You buy chips at the table by placing cash on the felt in front of you. The dealer does not take cash from your hand. The dealer spreads the cash, calls out the amount, and pushes chips toward you. You place your wager in the betting circle before any cards are dealt. Once the first card leaves the shoe, you cannot touch your bet.
The dealer gives each player two cards face up, then takes two cards, one face up and one face down. If the dealer's upcard is an ace, the dealer offers insurance before checking the hole card. Insurance is a side bet that the dealer has blackjack, and it carries its own house edge separate from the main bet.
Play proceeds around the table. Each player decides to hit, stand, double down, or split according to the cards and the table rules. The dealer acts last, after every player has finished. The dealer reveals the hole card and plays according to the printed standing rule. If the dealer busts by exceeding 21, all remaining player hands win. If the dealer does not bust, each hand is compared with the dealer's total: a higher total wins, a lower total loses, and an equal total pushes.
Blackjack, an ace plus a ten-value card on the first two cards, pays at the table's posted rate, commonly 3 to 2 or 6 to 5. The payout is printed on the felt. A 6 to 5 game pays less on blackjack than a 3 to 2 game and increases the house edge. Check this before you sit down, the same way you check the soft 17 rule.
Bet Types and How Their Edges Differ
Blackjack has a main bet and several side bets. The main bet is the one you place in the circle before the deal. Side bets are optional wagers on specific outcomes, such as whether your first two cards will form a pair or whether your cards plus the dealer's upcard will make a poker-style hand.
| Bet type | What it pays on | How the edge compares |
|---|---|---|
| Main bet | Your hand beating the dealer's without busting | Lowest house edge of the available bets under the table's rule set |
| Insurance | Dealer having blackjack when showing an ace | Separate side bet with its own, higher house edge |
| Pair or poker-style side bets | Specific combinations on your first cards | Higher house edge than the main bet; payouts are larger but rarer |
The main bet's edge depends on the rule set, including the dealer's soft 17 rule, the blackjack payout, the number of decks, and the doubling and splitting options. Side bets do not change the main bet's edge. They are separate wagers with their own, generally higher, house edges. A player who wants the lowest expected loss per hand plays the main bet and leaves the side bets alone.
Procedural Mistakes That Cost New Players
The most common mistakes at a blackjack table are not about strategy. They are about procedure, and they can cost money or slow the game for everyone.
The first mistake is touching the cards. In most shoe-dealt games, players never touch the cards. The dealer handles every card. In pitch games dealt from the dealer's hand, players may hold their cards, but only with one hand and above the table. If you are unsure, keep your hands away from the cards and wait for the dealer's instruction.
The second mistake is using hand signals incorrectly. The dealer cannot act on a verbal "hit" or "stand" alone in most casinos, because the cameras record hand signals, not words. To hit, tap the felt behind your bet. To stand, wave your hand horizontally over your cards. To double down, place an additional wager next to your original bet and hold up one finger. To split, place an equal wager next to the original and hold up two fingers. Learn the signals before your first hand, or ask the dealer to show you.
The third mistake is buying in or cashing out at the wrong moment. Do not hand cash to the dealer during a hand in progress. Wait for the settlement of the current round, then place your cash on the felt. When you leave, do not hand chips to the dealer to cash. Push them forward and ask for a colour-up, so the dealer converts smaller chips into larger denominations before you go to the cage.
Where the Exact Rule Is Stated
No article can tell you the soft 17 rule at the specific table you are about to play, because it varies by operator, by table, and sometimes by the stakes or the number of decks in the shoe. What an article can tell you is exactly where to look.
The rule is printed on the table layout itself, usually in the arc of text near the dealer's chip rack. It may say "Dealer must stand on all 17s" or "Dealer must draw to 16 and stand on all 17s" or "Dealer hits soft 17." If the felt is unclear, the rule is also stated in the game's information panel on an online table, or on the placard at the entrance to a live table's pit. The blackjack payout, usually 3 to 2 or 6 to 5, is printed in the same area. Read both before you place a bet.
FAQ
Does the dealer stand on 17 in every blackjack game?
No. The dealer always stands on hard 17, but the treatment of soft 17 varies. Some tables require the dealer to stand on all 17s, while others require the dealer to hit soft 17. The rule is printed on the table felt or in the game's information panel.
Why does hitting soft 17 help the dealer?
A soft 17 contains an ace counted as 11, so the dealer can take a card without any risk of busting on that hit. The dealer may improve to a stronger total. Over many hands, this raises the house edge slightly compared with standing on all 17s.
Does the dealer's standing rule change how I should play my hand?
Yes, on borderline decisions. A basic strategy chart is built for a specific rule set, and a chart for a stand-on-all-17s game is not necessarily correct for a hit-soft-17 game. Match your chart to the table's printed rules, including the soft 17 rule, the number of decks, and the doubling and splitting options.
