The dealer turns over an ace and a six, then reaches for another card. At the next table the same two cards stand, and nobody explains why.
Both dealers are holding a soft 17 in blackjack. They’re just working under two different house rules, and the rule the table uses quietly changes what every hand costs you.
Key Takeaways
- “Soft” means the hand counts an ace as 11 and can take another card without busting.
- Every table fixes one soft-17 rule for the dealer, and it’s printed on the felt or the rules panel.
- Power.Win’s Blackjack Original states its soft-17 rule in the game’s rules panel before you deal a hand.
- One dealer rule moves the house edge by a measurable fraction, and a worked example below puts a dollar figure on it.
- Your own soft 17 follows different logic from the dealer’s, because you have choices and the dealer has none.
This table shows the six hands people mix up most often, with what the dealer does under each rule.
| Dealer’s hand | Soft or hard | Total | Dealer action if the table is S17 | Dealer action if the table is H17 |
|---|---|---|---|---|
| A-6 | Soft (ace = 11) | 17 | Stands | Hits |
| A-2-4 | Soft (ace = 11) | 17 | Stands | Hits |
| A-A-5 | Soft (one ace = 11, one ace = 1) | 17 | Stands | Hits |
| 10-7 | Hard (no ace) | 17 | Stands | Stands |
| 9-8 | Hard (no ace) | 17 | Stands | Stands |
| 10-6-A | Hard (ace forced to 1) | 17 | Stands | Stands |
S17 means “dealer stands on soft 17”. H17 means “dealer hits soft 17”. The only rows that change between the two columns are the soft ones.
What is a soft 17 in blackjack?
A soft 17 is any blackjack hand totalling 17 in which an ace is counted as 11, such as ace-six. It’s “soft” because the ace can drop to 1 if the next card would push the hand over 21, so one more card can’t bust it.
The classic example is A-6: 11 plus 6 makes 17. But a soft 17 doesn’t need to be two cards. A-2-4 is soft 17 (11 + 2 + 4), and so is A-A-5, where one ace counts 11 and the other counts 1.
What makes a total soft is the ace’s flexibility, not the number of cards. Hit A-6 and draw a 10, and the ace falls back to 1: the hand becomes a hard 17 (1 + 6 + 10). Draw a 3 instead and you have a soft 20.
Does the dealer hit on soft 17 at online casinos?
At online casinos the dealer hits soft 17 only on games whose rules say H17: each blackjack game or live table fixes its own soft-17 rule before the first card, and the dealer never chooses. Power.Win’s Blackjack Original, for example, stands on soft 17. Look for “dealer stands on all 17s” or “dealer hits soft 17” on the felt or in the rules panel.
Dealer stands on soft 17 (S17)
Under S17, the dealer treats every 17 the same way, soft or hard, and stops drawing. If the dealer ends on A-6, your 18 wins, your 17 pushes and anything lower loses. It’s also the rule the Wizard of Odds uses as its baseline when it prices other rule changes.
Dealer hits soft 17 (H17)
Under H17, the dealer must take another card on any soft 17 and keep drawing until the hand reaches a hard 17 or better, or a soft 18 or better.
From A-6, a 2, 3 or 4 lifts the dealer to 19, 20 or 21. A 10 turns the hand into a hard 17, and a 7 or 8 turns it into hard 14 or 15, which means drawing again.
When does the dealer have to hit in blackjack?
The dealer must hit any total of 16 or less and stand on any hard 17 or higher, with the soft 17 rule deciding the one grey hand in between. Soft 18 and above always stand. Those rules are fixed, so the dealer’s play is completely predictable once you know which version the table uses.
The dealer’s decision, in order:
- 16 or less, hard or soft: hit.
- Hard 17 to 21: stand.
- Soft 17: stand under S17, hit under H17.
- Soft 18 to 21: stand.
The dealer doesn’t double, split, surrender or take insurance, and doesn’t react to what you’re holding. That’s why a dealer’s hand can be described with a flowchart and yours can’t.
Is dealer hitting soft 17 good or bad for you?
Dealer hitting soft 17 is bad for you: under the Wizard of Odds rule-variation table, H17 lowers your expected return by 0.22% compared with the same game played S17. Rounded, that’s about 0.2 percentage points added to the house edge on every dollar you bet.
A dealer who stands on soft 17 is stuck with a total that loses to 18 and only pushes against your 17. A dealer who hits gets another chance to improve that hand to 18 through 21. Sometimes the extra card makes things worse and the dealer busts, but across millions of hands the improvements win out.
The Wizard of Odds figure is measured against a stated baseline: eight decks, dealer stands on soft 17, double after split allowed. The Wizard of Odds rule-variation table lists each rule’s effect separately, and the Wizard of Odds house-edge calculator lets you switch S17 to H17 on your own rule set.
Worked example: what 0.22% costs over a session
Say you play 500 hands at $20 a hand. That’s $10,000 put through the table.
- Extra expected cost of H17: $10,000 × 0.22% = about $22
- Extra expected cost of a 6:5 natural payout: $10,000 × 1.39% = about $139
- Both rules on one table: roughly $161 more expected cost than the same table dealt S17 with a 3:2 payout
A 6:5 payout lowers your expected return by 1.39%, more than six times the cost of the soft-17 rule, according to the same Wizard of Odds table.
So H17 matters, but it’s not the biggest line on the rules card. The payout on a natural comes first, and our crypto blackjack sites checklist walks through that 6:5 gap in full.
None of these numbers is a prediction for one session. Over 500 hands the swings of ordinary luck are far larger than $22. The figures are long-run averages, and under either rule the house keeps its edge.
What’s the difference between soft 17 and hard 17?
A soft 17 counts an ace as 11 and can’t bust on the next card; a hard 17 either has no ace or has an ace forced to count as 1, so any card above a 4 busts it. Same total, very different hand.
That difference shapes how the two are played:
- Soft 17 in your hand is weak but safe to improve. Seventeen wins only when the dealer busts, and you can hit it for free because the ace absorbs a big card.
- Hard 17 in your hand is a stand. Basic strategy stands on hard 17 against every dealer up card, because the bust risk on the next card outweighs the gain. The one exception is surrendering it against an ace on an H17 table that offers surrender.
So which is better? For you, holding soft 17 is better than holding hard 17, because it gives you a free draw. For the dealer’s rule, S17 is better for you than H17. Both answers point the same way: flexibility helps whoever gets to use it.
What are the blackjack dealer rules?
Blackjack dealer rules are a fixed script: the dealer hits 16 or less, stands on 17 or more, follows the table’s soft-17 rule, and makes no decisions of their own. The rules card on each table spells out the variables that sit around that script.
The lines worth reading on any rules card:
| Rule | What it says | Why it matters to you |
|---|---|---|
| Soft 17 | S17 (stand) or H17 (hit) | H17 lowers your expected return by 0.22% |
| Natural payout | 3:2 or 6:5 | 6:5 lowers your expected return by 1.39% |
| Insurance | Offered when the dealer shows an ace | A side bet with its own price, separate from the main hand |
| Hole card | Whether the dealer checks for blackjack early | Decides whether a double or split can be lost to a dealer natural |
| Decks | How many decks the game deals from | Moves the edge by a smaller amount |
Deck count is its own topic, and our guide to how many decks are used in blackjack covers how it moves the edge. Tracking the cards that have been dealt is a separate subject again, covered in how card counting works in blackjack.
How does soft 17 change basic strategy?
H17 changes only a handful of basic-strategy decisions, almost all of them doubles you make more often because a dealer who keeps drawing is slightly weaker in some spots. The rest of the chart stays the same.
Two examples from standard multi-deck charts:
- Hard 11 against a dealer ace: hit under S17, double under H17.
- Soft 19 (A-8) against a dealer 6: stand under S17, double if allowed under H17.
The full chart, with every S17 and H17 cell marked, is on our blackjack basic strategy explained page, and there’s no need to relearn it here. Read the table’s soft-17 rule first, then use the chart that matches it.
Basic strategy trims the cost of your own mistakes. It doesn’t remove the house edge, under S17 or H17, and no betting pattern changes that.
What soft-17 rule do Power.Win’s blackjack tables use?
Power.Win’s Blackjack Original is an S17 game: its rules panel says the dealer “must hit on 16 or below and stand on 17 or above (including soft 17)”. The same panel states that a natural pays 3:2 and insurance pays 2:1.
The rules panel on the Power.Win Blackjack Original also lets you play up to three hands at once, each with its own bet. Because the dealer stands on soft 17, the 0.22% H17 cost from the worked example doesn’t apply to it.
The Original is one of the six PWR Originals that are provably fair. Before a hand, you see a SHA-256 hash of the server seed, you can set your own client seed, and a nonce rises by 1 with every bet.
The provably fair page explains how to check a hand after you rotate your seeds. Every hand you check that way is dealt on a site licensed by the Tobique Gaming Commission, licence 0000209, operated by 3-102-968317 SRL (Costa Rica).
Live dealer blackjack is different. Those tables in the Power.Win blackjack lobby come from certified third party providers rather than the provably fair Originals, and each one sets its own rules. If you play live dealer blackjack online, read the rules card on each live table for its soft-17 rule and natural payout before the first hand.

Frequently Asked Questions
How do you play a soft 20 like ace-nine?
Stand. Soft 20 is a total of 20 with an ace counted as 11, almost always A-9, and basic strategy stands on it against every dealer up card. It’s the second-strongest total in blackjack, and the soft label only reminds you the ace could drop to 1.
Is 2 aces and a 5 a soft 17?
Yes. Two aces and a 5 make soft 17: one ace counts 11, the other counts 1, and the 5 brings it to 17. Under an H17 rule the dealer hits this hand exactly as it would A-6.
Should you hit a soft 17 yourself?
Yes, basic strategy never stands on soft 17. It hits, or doubles against a dealer 3 to 6 where doubling is allowed. Seventeen wins only when the dealer busts, and the ace means one card can’t bust you. Hitting reduces your losses but doesn’t remove the house edge.
Does H17 cost more the faster you play?
Yes, because the 0.22% applies to every dollar you wager, not to the clock. If you play 100 hands in an hour at $10 a hand, that’s $1,000 wagered and about $2.20 more expected cost per hour at an H17 table than at an S17 one. A quick online game reaches that total sooner than a live shoe does.
Can a soft 17 turn into a hard 17?
Yes. When a soft 17 takes a card that would bust it with the ace at 11, the ace drops to 1. A-6 plus a 10 becomes hard 17 (1 + 6 + 10), and a dealer on an H17 table stands on that hand.
