A soft 17 is one of the most important rule variations in live blackjack, and it is one that most players walk past without noticing. The difference between a dealer who stands on all 17s and a dealer who hits soft 17 is worth 0.22% of house edge, which may sound small but translates directly into your practical loss rate across a session. At Flush, different blackjack variants use different soft 17 rules, and knowing which rule applies to your chosen table before you sit down is a concrete advantage.

This page explains what a soft hand is, why the soft 17 rule matters mechanically, which Flush blackjack variants operate under which rule, how basic strategy changes when the dealer hits soft 17, and what other soft hand situations you encounter regularly at the blackjack table.

Understanding soft hands is also foundational to blackjack basic strategy in general. Many of the basic strategy deviations that intermediate players miss involve soft hands: soft 18 doubling, soft 19 and 20 standing, soft 13 through soft 16 doubling or hitting. All of these decisions change depending on the dealer’s soft 17 rule. Flush makes the applicable rule visible in the game information panel before you join a table, which removes the guesswork.

What Is a Soft Hand in Blackjack?

A soft hand is any two-card (or multi-card) hand that contains an Ace counted as 11 rather than 1. The defining characteristic of a soft hand is that the Ace can be revalued to 1 without causing a bust, giving the hand two possible total values simultaneously.

The most basic example: an Ace and a 6 is a soft 17. The hand can be counted as either 7 (Ace as 1, plus 6) or 17 (Ace as 11, plus 6). The hand is soft precisely because hitting it cannot produce an immediate bust. If you draw a 10, the Ace reverts to 1 and the hand becomes 17. If you draw a 4, the hand becomes 21. If you draw a 7, the Ace stays at 11 and the hand is 24 on paper, but because Aces can revert, the hand is actually 14 (7 reverts Ace from 11 to 1, giving you 1+6+7=14).

This flexibility is what makes soft hands mathematically distinct from hard hands. A hard 17 (for example, 10-7) has no flexibility: hitting it with any card 5 or higher produces a bust. A soft 17 (Ace-6) can absorb any card without busting. This distinction is why the correct basic strategy for a soft hand often differs dramatically from the correct strategy for a hard hand of the same total.

Why Ace-6 Is Specifically a Soft 17

Ace-6 is the textbook example of a soft 17 because it is the two-card soft 17 and the one the dealer rule refers to. In its two-card form, Ace-6 has a total of either 7 or 17. As a two-card hand, it cannot be improved to anything other than 7 or 17 on a single-card draw without more options.

Other soft 17 combinations also exist in live blackjack at Flush. Ace-3-3 is soft 17 (Ace plus 3 plus 3, counted as 11+3+3=17 or 1+3+3=7). Ace-2-4 is soft 17. Ace-Ace-5 is soft 17 (if the first Ace counts as 11 and the second as 1 and 5 is added: 11+1+5=17). Any combination that produces two possible totals where the higher total is 17 qualifies as soft 17.

The dealer soft 17 rule applies to all of these configurations, not just the Ace-6 two-card version. When a dealer hits soft 17, the dealer draws an additional card any time their hand totals a soft 17 in any combination, until the hand is either hard 17 or above.

Why Dealers Hit Soft 17 in Some Variants

The casino’s motivation for offering a hit-soft-17 rule rather than standing on all 17s is straightforward: hitting soft 17 gives the dealer a mathematical advantage over standing. When the dealer stands on all 17s, the player’s basic strategy can account for the dealer’s fixed limitation. When the dealer hits soft 17, the dealer has more chances to improve from a vulnerable position.

The specific mechanism: a soft 17 is a weak dealer hand from the dealer’s perspective. Standing on soft 17 means the dealer’s hand cannot be improved. The player who holds 18, 19, 20, or 21 wins automatically. The player who holds a hard or soft 18 through 21 has a strong position against a standing dealer 17.

When the dealer hits soft 17, the dealer’s weak hand can improve to 18, 19, 20, or 21 on any draw (drawing A, 2, 3, or 4 respectively to a soft 17 stays soft or improves the total). Drawing 5 through 10 converts the soft 17 to a hard 12 through hard 17, and the dealer typically must hit again, adding another resolution layer to the hand.

The net mathematical effect of the dealer hitting soft 17 is that the dealer busts more often (because the dealer takes more cards) but also reaches better totals more often. The bust increase and the improvement increase both favor the house over different hand ranges, but the net effect is a 0.22% increase in house edge compared to a dealer who stands on all 17s.

The 0.22% House Edge Difference

The 0.22% figure for the soft 17 rule difference is one of the best-documented numbers in blackjack mathematics. It comes from simulation-based analysis of millions of hands under both rules at the same penetration, shoe size, and other rule conditions.

To put 0.22% in concrete terms: in a 100-hand session at $25 per hand, the total wagered is $2,500. The expected difference in loss between H17 and S17 rule sets is 0.22% of $2,500, which is $5.50. Over a 500-hand session at the same stake, the difference is $27.50. Over an extended high-volume session at higher stakes, the difference becomes more meaningful.

This matters at Flush because the choice between an H17 variant and an S17 variant is available in the live blackjack section. When you have the option to choose between two otherwise identical blackjack tables where one dealer stands on soft 17 and the other hits it, the S17 table is always the better mathematical choice by 0.22%.

The 0.22% is not recoverable through strategy adjustments alone. There are basic strategy modifications for H17 games (documented below), and applying them correctly reduces the strategy-based component of any additional house edge from H17 misplay. But the 0.22% that the rule itself costs cannot be offset through bet sizing, timing, or other approaches. The rule is the rule.

Flush Blackjack Variants and Their Soft 17 Rules

Flush carries multiple Evolution blackjack variants in the live casino section. The soft 17 rule varies by variant and is displayed in the game information panel within each table interface. The general pattern for commonly available Evolution formats is:

Speed Blackjack at Flush: dealer hits soft 17. Speed Blackjack is Evolution’s rapid-deal format where cards are assigned to players who act first, creating a faster pace. The H17 rule applies in Speed Blackjack, adding 0.22% to the house edge compared to an S17 equivalent.

Infinite Blackjack at Flush: dealer hits soft 17. Infinite Blackjack allows unlimited players at a single hand, with all players receiving the same two community cards and making individual decisions from the same starting point. The H17 rule applies in the standard Infinite Blackjack format at Flush.

Free Bet Blackjack at Flush: dealer stands on all 17s including soft 17. Free Bet Blackjack compensates for its free doubling and splitting mechanic (the casino pays for doubles and splits on qualifying hands) by using a special “push 22” rule (dealer 22 pushes against all player non-busted hands). The S17 rule applies to standard soft 17 in Free Bet Blackjack, and the push 22 rule is separate from and in addition to the standard S17 rule.

Always confirm the specific soft 17 rule for any Flush blackjack variant in the game information panel. Evolution occasionally updates game configurations, and Flush displays the current certified rule set within the table interface before you join.

How Soft 17 Changes Basic Strategy for Players

When the dealer hits soft 17, several basic strategy decisions change for players compared to a dealer-stands-on-soft-17 game. The most important player strategy changes in H17 games are:

Double soft 18 (Ace-7) against a dealer 2 in H17 games. In S17 games, the standard strategy is to stand with soft 18 against a dealer 2. In H17 games, doubling soft 18 against a dealer 2 is marginally better due to the dealer’s increased likelihood of improving from soft 17 hands.

Double soft 19 (Ace-8) against a dealer 6 in some H17 rule sets. This deviation from standard strategy is rare and applies only in specific rule configurations with favorable doubling rules.

Surrender 15 against a dealer Ace in H17 games. In S17 games, surrender 15 against dealer Ace is borderline. In H17 games, the dealer’s increased chance of reaching 17-21 by hitting soft 17 shifts the EV toward surrender with 15 against an Ace.

The overarching principle: H17 games increase the dealer’s reaching-17-or-better probability, which in turn makes more player hands vulnerable. Basic strategy in H17 games should generally be slightly more aggressive on double-down opportunities against weak dealer cards (because the dealer is more likely to bust or land weak with certain upcards in specific configurations) and more defensive on player stiff hands against Ace (because the dealer is more likely to improve to 17+).

Soft Hand Situations from Soft 13 Through Soft 21

Soft 13 through soft 21 each have distinct basic strategy recommendations that apply independently of the dealer’s soft 17 rule, though the H17 rule creates some modifications as noted above. The following covers the standard S17 basic strategy recommendations for player soft hands:

Soft 13 (Ace-2) and Soft 14 (Ace-3): double against dealer 5 and 6. Hit in all other situations. These are the weakest soft hands and have limited doubling opportunities.

Soft 15 (Ace-4) and Soft 16 (Ace-5): double against dealer 4, 5, and 6. Hit in all other situations. The doubling range expands slightly compared to soft 13/14.

Soft 17 (Ace-6): double against dealer 3, 4, 5, and 6. Hit in all other situations including against dealer 2 (in S17 games). In H17 games, some rule sets extend the double against dealer 2 for soft 17 as well.

Soft 18 (Ace-7): double against dealer 3, 4, 5, and 6. Stand against dealer 2, 7, and 8 (soft 18 beats dealer’s most likely non-10 outcomes). Hit against dealer 9, 10, and Ace (dealer’s strong showing makes standing on soft 18 a losing proposition in those matchups).

Soft 19 (Ace-8): stand in all situations in standard S17 games. Soft 19 is strong enough that no standard double or hit recommendation applies. In specific H17 rule sets with liberal doubling rules, doubling soft 19 against dealer 6 may produce a marginal gain.

Soft 20 (Ace-9): stand always. This is a near-perfect hand and doubling or hitting would be a significant strategy error at Flush.

Soft 21 (Blackjack): pays 3:2 at Flush on initial two-card 21s. This outcome is final and requires no decision.

How to Check the Soft 17 Rule Before Playing at Flush

Every live blackjack table at Flush displays the applicable rule set in the game information panel. To access it, click the information icon within the table interface before joining. The panel displays:

Number of decks in the shoe Dealer soft 17 rule (H17 or S17) Blackjack payout (3:2 or 6:5) Double-down rules (any two cards, 9-10-11 only, etc.) Splitting rules (resplit Aces, split to how many hands) Surrender availability

The soft 17 rule is displayed clearly as “Dealer stands on soft 17” or “Dealer hits soft 17.” This information is available before you join the table and before any chips are placed at Flush. Making the rule-check a habit before joining any new blackjack table is a straightforward step that costs nothing and saves you from playing an H17 game without adjusting your strategy accordingly.

Practical Effect on a 100-Hand Session

Consider a player at Flush running 100 hands of blackjack at $50 per hand. Total wagered: $5,000. In an otherwise identical game:

S17 rule (dealer stands on soft 17): house edge approximately 0.50% (assuming single deck or six-deck S17 with standard rules). Expected loss: approximately $25 over 100 hands.

H17 rule (dealer hits soft 17): house edge approximately 0.72% with the same other rules. Expected loss: approximately $36 over 100 hands.

The difference of approximately $11 over 100 hands at $50 per hand is not catastrophic, but it is measurable. At $200 per hand over 100 hands, the difference approaches $44. At high-stakes live blackjack play, the soft 17 rule becomes an increasingly meaningful selection criterion for players who want to minimize their theoretical loss rate at Flush.

Soft 17 Rule Impact on Player Basic Strategy Decisions

The soft 17 rule at a given blackjack table changes the correct basic strategy for players in a small but meaningful number of situations. When a dealer must stand on soft 17 (S17 rule), the dealer’s overall bust rate is marginally lower than when the dealer must hit soft 17 (H17 rule), because the hit gives the dealer an additional chance to improve a weak total. The H17 rule increases the house edge by approximately 0.22 percentage points over the S17 rule in standard multi-deck blackjack.

For players, the soft 17 rule adjustment to basic strategy affects a handful of double-down decisions. Against a dealer Ace at an H17 table, doubling down on soft 18 (Ace-7) becomes correct in some configurations where it is not at an S17 table, because the dealer’s hitting obligation on soft 17 increases their bust exposure. Similarly, doubling on 11 against a dealer Ace is correct at H17 tables in standard multi-deck, where it is not at S17 tables.

Players at Flush who learn basic strategy from a standard chart without knowing the table’s soft 17 rule may apply sub-optimal decisions in these specific spots. The adjustment is not large in frequency, but knowing which table type you are sitting at is a prerequisite for fully optimized play.
