UKUnderstanding the Blackjack Soft 17 Rule at the Casino – Can the Dealer Hit?
Not all blackjack tables follow the same rules, and some of those differences can affect your chances of winning. One worth paying attention to is the soft 17 rule, which determines whether the dealer must hit or stand on a particular hand. It’s easy to overlook when choosing a table, especially if you’re new to blackjack.
The difference might seem minor, but it can affect the house edge and the decisions you make during a game. We’ll explain what soft 17 means, how the dealer’s rules work, and where you might need to adjust your blackjack strategy.
What Is a Soft 17 in Blackjack?
A soft 17 in blackjack is a hand totaling 17 that contains an Ace counted as 11, such as Ace + 6. The Ace can also count as 1, bringing the hand’s value down to 7 if needed. This flexibility means you can draw another card without immediately risking a bust.
For example, if you hit a soft 17 and receive a 9, your Ace switches to a value of 1, leaving you with a hard 16 instead of 26. A hard 17 doesn’t offer the same protection because it either has no Ace or contains one already counted as 1.
Players can choose whether to hit or stand on soft 17, with basic strategy generally recommending another card. Dealers must follow the table’s rules, which specify whether the dealer hits or stands on soft 17. That distinction matters because allowing the dealer to hit increases the house edge.

Dealer Hits vs. Stands on Soft 17: Rule Comparison
Whether the dealer hits or stands on soft 17 affects the house edge and your expected losses over time. Tables where the dealer stands generally offer better odds, while hitting on soft 17 increases the casino’s advantage by approximately 0.22%.
Here’s a quick comparison of how the two rules affect blackjack:
| Feature | Dealer Stands on Soft 17 | Dealer Hits on Soft 17 |
|---|---|---|
| Dealer Action | Must stand on any hand totaling 17 | Must draw another card on soft 17 |
| Example Hand | Ace + 6 = 17 (stand) | Ace + 6 = 17 (hit) |
| Effect on House Edge | Lower house edge | Approximately 0.22% higher |
| Example House Edge | 0.56% | 0.78% |
| Expected Hourly Loss | $7.84 | $10.92 |
| Better for Players? | Yes | No |
Soft vs. Hard vs. Stiff Hands in Blackjack
Knowing the difference between soft and hard hands can help you make better decisions at the blackjack table. You might also hear players refer to a hand as “stiff,” which usually means they’re in a difficult position where taking another card could cause them to bust.
Here’s how the three types of hands compare:
| Hand type | Example | What it means |
|---|---|---|
| Soft hand | Ace + 6 = Soft 17 | The ace counts as 11 but can switch to 1 to avoid busting. |
| Hard hand | 10 + 7 = Hard 17 | The hand has no ace counting as 11, making it riskier to hit. |
| Stiff hand | 10 + 6 = Hard 16 | A hard total between 12 and 16 that could bust with another card. |
A hard 17 in blackjack is a hand worth 17 without an ace counting as 11. Unlike a soft 17, you don’t have the flexibility of changing the ace’s value if you draw another card. Basic blackjack strategy generally recommends standing on hard 17 rather than risking a bust.
Stiff hands are a little trickier. These are usually hard totals between 12 and 16, where hitting could put you over 21. Standing isn’t always a great option either, particularly when the dealer is showing a strong card.
Understanding these differences helps when deciding whether to hit or stand. It also gives you a better idea of why the dealer’s soft 17 rule matters and how it can affect the game.
Does the Blackjack Dealer Hit or Stay on a Soft 17?
Most online and land-based casinos have house rules for how blackjack dealers play. The most common setup is as follows:
- Stand on a hand of 17 or higher
- Hit on a hand of 16 or less
However, the soft 17 rule adds a twist. Most casinos have the dealer stand on a soft 17, meaning they cannot use their ace to its full advantage the same way the player can. But, when the rule changes to “dealer hits on a soft 17,” the dealer now has more chances to improve their hand. This one change gives the house a slightly bigger edge, which is never good news for players.
So, the first basic strategy for blackjack is to check the table rules before you sit down. If you see the dealer hitting on soft 17, it’s usually smart to walk away and find a table that treats 17 as a hard stop. Otherwise, understand you’re playing at a disadvantage and adjust your strategy accordingly. Players can typically find this rule written on the felt of the table or by simply asking the dealer.
When the dealer hits on soft 17, the house edge increases by approximately 0.22% compared to tables where the dealer stands, making it the less favorable option for players.
How Your Strategy Changes Based on Soft 17
Think of basic blackjack strategy as your blueprint at the table. It’s a set of moves designed to cover every possible hand you might get and every card the dealer might show. It won’t guarantee wins, but it will help you minimize mistakes, extend play, and keep the house edge as low as possible. You can check out our Blackjack Basic Strategy Guide for the scenarios in which you should hit, stand, double down, or split.
But keep in mind that the strategy depends on the blackjack variant you’re playing – whether it employs the Soft 17 Rule or not. If the dealer stands on a soft 17, the game is generally better for players. You don’t need to make as many adjustments, since the dealer is stopping earlier and giving away a bit of their edge.
But if the dealer hits on a soft 17, things change. The house has a stronger hand in the long run, so you’ll need to tweak your own decisions to balance it out. These adjustments mostly show up in how you handle soft hands and doubling down opportunities.
Key Adjustments to Remember (If the Dealer Hits on Soft 17):
- Double down on 11 vs. dealer ace.
- Double down on soft 19 vs. dealer 6.
- Double down on soft 18 vs. dealer 2.
- Hit a soft 18 vs. dealer ace in single-deck games.
- In 4+ deck games: double down on soft 17 vs. dealer 2.
These may look like small tweaks, but they’re important. Knowing when to shift gears at tables where the dealer hits on soft 17, keeps you close to optimal play.
How House Edge Changes Based on Soft 17
The average house edge for blackjack (when playing with a perfect strategy) is roughly 0.5%. However, when the dealer hits a soft 17 instead of standing on it, the house edge goes up to 0.22%. While this may not seem like much, the difference is huge in the long run.
For example, let’s say a game has a house edge of 0.56%, meaning the house is mathematically expected to win 56 cents. If your average bet size is $20, and you play 70 hands per hour, then your expected hourly loss is as follows:
- $20/hand x 70 hands/hour x 0.56% = $7.84/hour
If the dealer hits a soft 17 instead of standing on it, the house edge jumps to 0.22%. Let’s see what that means for you:
- $20/hand x 70 hands/hour x 0.22% = $10.92/hour
With this slight change, your average hourly loss increases 1.5 times from $7.84 to $10.64.
Who Benefits the Most from the Soft 17 Rule?
Some players believe the soft 17 rule helps them because the dealer is more likely to bust. While that’s technically true, the dealer’s hand also improves often enough to outweigh the extra busts.
According to Mike Aponte’s example, if a dealer hits on a soft 17, their chance of busting only goes up by 0.4%. However, their odds of finishing with a total of 18–21 tick upward by 0.8%.
The math is clear: the soft 17 rule gives the casino a stronger edge, not the player. So, it’s your best options to stick to tables where the dealer stands.
