The Soft 17 Rule in Blackjack (2023)

The “soft 17 rule” is a rule that requires the dealer to hit on soft 17. For many blackjack players, this rather innocuous rule doesn’t seem like a big deal, but the fact of the matterThe Soft 17 Rule in Blackjack (1)Henry Tamburin is the editor and publisher of the Blackjack Insider Newsletter and author of the best-selling Blackjack: Take the Money & Run.

First, a quick review of what we mean by a soft hand. Any blackjack hand that contains an ace counted as an 11 is a soft hand.An ace-6 hand is a soft 17 and so is an ace-3-3 hand. These hands are played much differently than their corresponding hard hands. For example, ace-6 is soft 17 whereas 10-7 and 7-9-ace hands are hard 17’s (notice that if your hand contains either no ace, or one or more aces that are each count as one, the hand is hard).The reason the distinction is made between soft and hard hands is that they are played quite differently. For example, a player who is dealt a 10-7 should always stand whereas a player who is dealt an ace-6 should never stand.

In the world of blackjack some casinos require dealers to stand when their hand is a soft 17 (designated as s17), whereas others require dealers to hit soft 17 (i.e. they have implemented the soft 17 rule or h17). You can always tell whether a casino has the soft 17 rule or not by reading the wording on the table layout. If it reads “Dealer Must Stand on all 17’s” it means the dealer will stand on soft 17. If instead it states “Dealer Hits Soft 17”, it means the dealer will hit soft 17.

What happens to the odds when the soft 17 rule is in effect? Usually the dealer will bust more often which is good for the player. However, when he doesn’t bust, what would have been a 17 often ends up to be a higher hand that more often then not will beat the player’s hand. Overall the player’s net expectation is reduced by 0.20% with the soft 17 rule which is another way of saying the casino’s edge over a blackjack player increases by that amount. The soft 17 rule, therefore, favors the casino not the player.

Fortunately, there aren’t too many adjustments that you need to make to the basic playing strategy if you are playing in a game with h17. When you are playing, in general you should:

double down on 11 against a dealer’s ace

double down on soft 19 against the dealer’s 6

double down on soft 18 against the dealer’s 2

A more accurate set of playing strategy modifications that takes into effect the number of decks of cards being used is summarized below. Notice the additional hands that you should surrender with h17. The reason is because the player’s chance of winning these hands decreases enough with h17 compared to s17, that surrender becomes the better option.

Modifications to Basic Playing Strategy for Soft 17 Rule

Single Deck

Hit soft 18 against ace

If double after pair splitting is allowed, split a pair of 9’s against an ace

If surrender is allowed, surrender hard 15 against an ace and hard 17 against an ace.

Double Deck

Double down on soft 14 against 4

Double down on soft 18 against 2

Double down on soft 19 against 6

If surrender is allowed, surrender hard 15 against dealer ace.

4, 6 or 8 Decks

Double down on 11 against an ace

Double down on soft 17 against 2

If surrender is allowed, surrender hard 15 against ace, hard 17 against ace, and a pair of 8’s against dealer ace.

Unfortunately, the number of casinos that are switching to the soft 17 rule is increasing. I can remember not too long ago when nearly 100% of the strip casinos in Las Vegas had the s17 rule on their shoe games. That’s not the case anymore. Based on the information of blackjack playing conditions reported in Stanford Wong’s “Current Blackjack News” only 17% of the Strip casinos offer “only s17 games”, 40% “only h17”, and 43% a mix of s17 and h17 games. Also, just about all the casinos that cater to local players offer only h17 games and ditto for the majority of casinos located in the downtown area.

However, you shouldn’t judge a blackjack game solely on the h17 rule. Why?Because even though the casino gains an extra 0.20% with the soft 17 rule, many casinos in Las Vegas and elsewhere also give some of that edge back to the player by offering single or double deck games in lieu of 6 or 8 deck games. Throw in a few more player favorable rules, such as double after pair splitting (das), resplit of aces (rsa), or late surrender (ls), and all of a sudden a h17 game isn’t such a bad game after all.

For example, summarized below is the casino’s edge for typical blackjack games you will find in Las Vegas (this of course excludes those dastardly 6-5 single games which you should not play). . Note that the casino edge over a basic strategy player for a single deck game with h17 is only 0.18%, a good blackjack game by anyone’s standard. Compare that with the rather high 0.79% for the comparable 6-deck game. In fact even a h17, 6 deck game with a bunch of added player favorable rules still only makes the game average for basic strategy players by Vegas standards.

Effect of Playing Rules on Casino’s Edge in H17 Games

h17 = dealer hits soft 17

das = player can double down after pair splitting

rsa = player can replit aces

ls = late surrender is offered

# Decks Rules Casino Edge

Single deck h17 0.18%

Single deck h17, rsa 0.15%

Single deck h17, das 0.06%

Double deck h17 0.53%

Double deck h17, rsa 0.48%

Double deck h17, das 0.40%

Double deck h17, das, rsa 0.35%

Double deck h17, das, rsa, ls 0.28%

6 deck h17 0.76%

6 deck h17, rsa 0.69%

6 deck h17, ls 0.67%

6 deck h17,das 0.63%

6 deck h17, das, rsa 0.56%

6 deck h17, das, ls 0.54%

6 deck h17, das, ls, rsa 0.46%

You can of course reduce the casino edge in 6 (or 8) decks by simply playing in a casino that offers the s17 rule rather than h17. For example several Strip casinos offer these set of rules in their 6-deck game: s17, das, ls, and rsa.The casino edge over the basic strategy player is only 0.26%, which is 0.20% lower then the best 6 deck, h17 game. Likewise a 2 deck, s17, das game has a casino edge of only 0.19%, which is 0.21% lower than the corresponding 2 deck, h17, das game.

In northern Nevada most casinos offer single deck games with h17 but they restrict doubling to only hard 10 and 11. The latter is a casino player favorable rule that results in this game having a casino edge of 0.44% (ie. it converts a good blackjack game to at best average).

The bottom line is that the soft 17 rule is tolerable in a single deck game (with no restrictions on doubling) and also in a double deck game if das, rsa, or lsis offered. For 6 (or 8) deck games, given a choice between h17 or s17 game, you are better off playing a s17 game.
