Soft 17 is a blackjack hand worth 17 in which an ace is being counted as 11, the plainest example being an ace with a six. The term turns up in two places: in the table rule that tells the dealer whether to draw on it, and in your own decisions when you hold that total. Both are covered below, for readers aged 18 and over.
Soft hands and hard hands
An ace counts as 1 or 11, whichever helps the hand. A hand is soft while it holds an ace that can still be valued at 11 without pushing the total past 21. Because that ace can always fall back to 1, a soft hand cannot bust on the next card. A hard hand has no ace, or has one that is already stuck at 1.
| Cards | Total | Type |
|---|---|---|
| Ace + 6 | 7 or 17 | Soft 17 |
| Ace + 2 + 4 | 7 or 17 | Soft 17 |
| 10 + 7 | 17 | Hard 17 |
| Ace + 6 + 10 | 17 | Hard 17 (the ace is now worth 1) |
| Ace + Ace | 2 or 12 | Soft 12 |
The fourth row is the one that confuses newcomers. When a ten-value card lands on soft 17, counting the ace as 11 would give 27, so the ace quietly switches to 1 and the hand becomes hard 17. Nothing was lost by drawing; the hand simply changed character.
The dealer's rule: H17 or S17
The dealer has no choices. Every blackjack dealer draws on 16 or less and stands on hard 17 or more, but soft 17 is handled in one of two ways, and the table states which:
- S17, often printed as "Dealer stands on all 17s": the dealer stops on soft 17 just as on any other 17.
- H17, printed as "Dealer must hit soft 17": the dealer takes another card while holding soft 17.
At a land-based table the wording is usually printed on the felt next to the payout line. Online, it tends to sit in the game rules behind the help or information button rather than on the table graphic, so a quick look before the first hand is worthwhile.
Why drawing on soft 17 favours the house
A standing 17 is a modest total. It loses to every 18 to 21 and only beats lower standing hands, which players often keep when the dealer shows a weak card. When the dealer draws to soft 17 instead, the next card cannot cause a bust, and a fair share of draws improve the hand to 18 or better. Some rounds the player would have pushed or won turn into dealer wins. The effect usually quoted is an increase of about two-tenths of a percentage point in the house edge, which sounds tiny but is larger than many of the rule details people argue about at the table.
Handling your own soft 17
You are not bound by the dealer's rule, and soft 17 is a hand where standing is a frequent error. Seventeen feels respectable, yet it wins less often than people expect, and a draw cannot bust a soft hand. The worst a single card can do is leave a weaker hard total, such as ace, six and five making hard 12, which then needs another decision. For that reason, basic strategy charts never stand on soft 17: they hit it, or double down when the dealer shows a weak card.
The table below follows a typical multi-deck chart for an S17 game. On H17 tables a few cells shift slightly towards doubling, so treat it as a guide to the logic rather than a rulebook.
| Your soft hand | Usual play |
|---|---|
| Soft 13 or 14 (A-2, A-3) | Double against a dealer 5 or 6, otherwise hit |
| Soft 15 or 16 (A-4, A-5) | Double against 4 to 6, otherwise hit |
| Soft 17 (A-6) | Double against 3 to 6, otherwise hit |
| Soft 18 (A-7) | Double against 3 to 6; stand against 2, 7 or 8; hit against 9, 10 or ace |
| Soft 19 and above | Stand |
Where doubling is not permitted, the doubling cells become hits, apart from soft 18, which then stands against 3 to 6. The reasoning behind these choices, and the rest of the chart, is set out in our guide to blackjack basic strategy, and the mechanics of the doubled bet are covered in when to double down in blackjack.
Mix-ups worth avoiding
- Reading H17 as "dealer hits 17". Only soft 17 is affected. A dealer holding ten and seven stands at every table.
- Counting a hand as soft after the ace has switched. Once the ace has to be worth 1, the hand is hard, and busting becomes possible again.
- Assuming every table uses the same rule. Two games in the same room, or two titles from the same provider, can differ.
- Standing on soft 17 because it "already beats a 16". The dealer never finishes on 16, so that comparison never arises.
Short answers to common questions
Can a hand with two aces be soft?
Yes. Ace and ace is soft 12, since only one ace can count as 11; two of them at 11 would make 22. Most players split this pair rather than play it as a single hand.
Is S17 always the better table?
With every other rule equal, yes. Other details weigh more, though. A blackjack paid at 6 to 5 instead of 3 to 2 costs far more than the soft 17 rule, so read the whole rules panel rather than one line. The full set of table rules is explained in how to play blackjack.
Does the rule apply to online blackjack too?
It does. Software dealers follow programmed rules exactly as human ones follow house procedure, and the soft 17 setting is part of each game's published rules.
Blackjack is a pastime for adults and costs money over time whatever the rules. Settle on a spending ceiling before the first hand, and confirm that card games for real money are permitted where you live.
