The Definitive Guide to Blackjack Dealer Rules
Welcome to the ultimate resource for understanding blackjack dealer rules for 2025.

The Core Blackjack Dealer Rules: What a Dealer MUST Do
The most important thing to remember is that the dealer has no strategy. They are like a robot, following a fixed script on every single hand. Understanding this script is fundamental to your own success. Let’s break down each mandatory action.
Hitting on 16, Standing on 17: The Golden Rule
This is the cornerstone of all blackjack dealer rules. It’s a simple, two-part command that never changes for hard hands.
- The dealer must hit any hand total of 16 or less.
- The dealer must stand on any hand total of a hard 17 or more (e.g., a 10 and a 7, or a 9 and an 8).
To put it simply:
- Dealer has 15 ➞ Must Hit
- Dealer has 16 ➞ Must Hit
- Dealer has Hard 17 ➞ Must Stand
- Dealer has 18 ➞ Must Stand
The Soft 17 Exception: The Most Important Rule Variation
A “Soft 17” is a hand that contains an Ace and totals either 7 or 17 (e.g., Ace + 6). How the dealer plays this specific hand is the most significant rule variation you will encounter, and it directly impacts the house edge.
- S17 (Stand on Soft 17): In these games, the dealer must stand with a soft 17. This rule is more favorable to the player.
- H17 (Hit on Soft 17): Here, the dealer must take another card on a soft 17. This rule increases the house edge by approximately 0.22%.
Always check the table felt before you play; the rule will be printed directly on it (e.g., “Dealer Must Stand on 17 and Hit on Soft 17”).
How the Dealer Uses an Ace
The dealer’s Ace follows the same flexible rule as the player’s. It always counts as 11 unless that value would cause the hand to bust (go over 21). If counting the Ace as 11 would result in a bust, its value automatically reverts to 1. The dealer has no say in this matter. For example, if a dealer has an Ace and a 5 (total 16), they must hit. If the next card is a 9, the hand would be A+5+9. To avoid busting at 25, the Ace’s value becomes 1, making the new total 15 (1+5+9). The dealer must then hit again.
The Dealer’s “No Choices” Policy
Unlike players, dealers are strictly forbidden from making any strategic decisions to improve their hand. This is a crucial limitation that players can exploit with basic strategy.
- Dealers cannot split pairs.
- Dealers cannot double down.
- Dealers cannot surrender their hand.
How Dealer Rules Affect Your Game
Understanding the dealer’s limitations is not just trivia; it directly informs your best course of action. Here’s how these fixed rules impact the most common scenarios at the table.
The Push: What Happens in a Tie?
A “push” is simply a tie between you and the dealer. When this happens, you neither win nor lose, and your original bet is returned to you. A push occurs in two main situations:
- You and the dealer end up with the same hand total (e.g., you both have 19).
- Both you and the dealer are dealt a natural blackjack (an Ace and a 10-value card on the first two cards).
Crucial Clarification: If you get a natural blackjack and the dealer’s final hand totals 21 but is made up of three or more cards, you win! A two-card 21 always beats a multi-card 21.
Insurance: A Bet on the Dealer’s Hand
When the dealer’s upcard is an Ace, you will be offered an optional side bet called “Insurance.” This is a bet that the dealer’s face-down card is a 10, Jack, Queen, or King, giving them a natural blackjack. If you take Insurance and the dealer has blackjack, the side bet pays 2:1. However, mathematically, Insurance is a bad bet for the average player. It carries a high house edge, and experts recommend avoiding it unless you are a professional card counter.
A Step-by-Step Guide: Playing a Hand Against the Dealer
Here is the sequence of events for a typical round of blackjack, showing how the dealer’s actions fit into the game.
- Players Place Bets: You start by placing your chips in the betting circle.
- The Dealer Deals: The dealer gives one card face-up to every player, then one card face-up to themselves. A second face-up card is then dealt to each player, followed by one card face-down for the dealer (the “hole card”).
- Dealer Checks for Blackjack: If the dealer’s upcard is an Ace or a 10-value card, they will check their hole card for blackjack. If they have it, the hand ends immediately. All player bets lose, except for players who also have blackjack (which results in a push).
- Players Play Their Hands: If the dealer does not have blackjack, play proceeds. Starting with the player to the dealer’s left, you decide to hit, stand, double down, or split based on your hand and the dealer’s upcard.
- The Dealer Plays Their Hand: Once all players have completed their actions, the dealer reveals their hole card. They then must play out their hand according to the fixed house rules: hitting until their total is 17 or more.
- Payouts: The dealer compares their final hand to each player’s hand. If your hand is higher than the dealer’s, or if the dealer busts, you win. If the dealer’s hand is higher, you lose.
Odds and Payouts Influenced by Dealer Rules
The rigid nature of the dealer’s play creates predictable probabilities that form the foundation of basic strategy. Understanding these payouts and odds is essential.
Standard Payouts Table
| Outcome | Payout | Notes |
|---|---|---|
| Player Win | 1:1 | Your hand is higher than the dealer’s without busting. |
| Player Blackjack | 3:2 | A natural 21. Avoid tables that pay 6:5. |
| Insurance Win | 2:1 | You win the side bet if the dealer has blackjack. |
| Push/Tie | Bet Returned | You and the dealer have the same hand total. |
Dealer Bust Probability by Upcard Table
Your strategy should change based on the dealer’s visible card. This table shows why.
| Dealer’s Upcard | Probability of Busting | Player Strategy Note |
|---|---|---|
| 2, 3, 4 | 35-40% | Dealer is relatively weak. Be more conservative with hitting. |
| 5, 6 | ~42% | Dealer is most likely to bust. Avoid hitting your stiff hands (12-16). |
| 7, 8, 9 | 24-26% | Dealer has a strong hand. You may need to be more aggressive. |
| 10, J, Q, K | 21% | Dealer is very strong. Play assuming they have a 20. |
| Ace | 17% | Dealer is very strong. |

Common Mistakes to Avoid
Players often make unforced errors by forgetting or misinterpreting the dealer’s rules. Avoid these common pitfalls:
- Not checking the Soft 17 rule: Playing an H17 table with an S17 strategy is a costly mistake. Always check the felt.
- Always taking Insurance: It’s a high house edge bet. Ignore it unless you are a professional card counter.
- Panicking when the dealer shows a 5 or 6: This is the dealer’s weakest position. Don’t hit your hard 12-16 and risk busting when the dealer is most likely to bust themselves. Stand your ground!
Bankroll Management and Responsible Gaming
Blackjack is a game of skill and chance, but the house always has a long-term edge. To ensure you play safely and enjoyably, always practice responsible gaming.
- Set a firm budget for your session and stick to it.
- Never chase losses. Accept that wins and losses are part of the game.
- Play for entertainment, not as a way to make money.
Always play responsibly. If you feel you may have a gambling problem, please seek help from a professional organization.
Frequently Asked Questions (FAQ)
What are the dealer rules in blackjack?
The core rules are that the dealer must hit on all hand totals of 16 or less and must stand on all hard totals of 17 or more. The main variation is whether they must hit or stand on a soft 17 (an Ace and a 6).
Does the dealer hit on a soft 17?
This depends entirely on the casino and the specific table. Games where the dealer hits on soft 17 are marked “H17,” while games where they stand are marked “S17.” S17 rules are more favorable for the player.
What happens if you get blackjack and the dealer gets 21?
If you get a natural two-card blackjack (Ace + 10) and the dealer achieves a total of 21 with three or more cards, you win and are paid 3:2. If both you and the dealer get a natural blackjack, the hand is a push, and your bet is returned.
Is an ace a 1 or 11 for the dealer?
An Ace is counted as 11 unless doing so would cause the dealer’s hand to exceed 21. In that case, its value automatically switches to 1. The dealer has no choice in this; it is a fixed rule.
Do blackjack dealers have to hit on 16?
Yes, absolutely. This is a universal rule in all standard versions of blackjack. The dealer must always take another card on any hand total of 16, whether it’s a hard 16 (like 10+6) or a soft 16 (like A+5).
