Ever wondered why so many players talk about dealer busts in blackjack? Whether you’re new to the table or just curious about how it all works, understanding what happens when the dealer goes over 21 could make the game much clearer.
There’s a straightforward reason people watch dealer busts closely. The odds behind them shape how blackjack plays out and help explain why certain hands feel more comfortable than others.
This post looks at what a dealer bust actually is, how often it tends to happen, and the main factors that influence it across both online and in-person games. Read on to learn more.
What Does It Mean When a Dealer Busts in Blackjack?
In blackjack, both you and the dealer aim for a total as close to 21 as possible, without going over. Number cards count as their face value, face cards are worth 10, and an Ace can be 1 or 11.
If the dealer’s total exceeds 21, they bust and lose the round. If you’ve stayed under 21, your hand wins against a dealer bust. Not every round ends this way, and the dealer’s actions are defined by the table rules.
Most games require the dealer to hit on 16 or less and stand on 17 or more. Some tables treat a soft 17 differently, which matters later on. If you’re playing online, the game information panel shows the exact rules used for that table.
If you decide to try your hand at blackjack, remember to do so responsibly and within your means; never wager more than you can afford to lose.
How Often Do Dealers Bust in Blackjack?
Dealers bust less often than many people expect. Under common rules, the overall dealer bust rate sits around 28%. That average shifts a little with different table rules and deck setups, but it stays in the same ballpark.
The dealer’s upcard plays a big part. When the upcard is a 2 through 6, the bust rate is higher, typically around the mid-30s to just over 40%, with 5s and 6s being the most fragile starts. With stronger upcards like 7, 8, 9 or 10, the bust rate drops to the low-to-mid 20s, and with an Ace it falls closer to around 12%.
What Factors Affect a Dealer’s Bust Rate?
Dealer Upcards and Their Impact
The visible card at the start of the round sets the tone. Low and mid upcards such as 4, 5 and 6 often force the dealer to draw more cards to reach a standing total, which increases the chance of going over 21. High upcards like a 10 or Ace do the opposite by starting the dealer closer to a finished hand.
You do not need to memorise a chart to follow this. It is enough to recognise that weaker upcards make a bust more likely, while stronger upcards reduce it.
Table Rules and Dealer Behaviour
House rules determine when the dealer must hit or stand. Two details matter most:
- Soft 17: If a table requires the dealer to hit on soft 17, they will take more cards and complete more hands, which slightly reduces overall bust rates compared with standing on all 17s.
- Decks and shuffling: Multiple decks and automatic shuffling affect card flow only slightly from a player’s point of view, but they help keep each round independent.
You can see these rules in the game information panel before you start. Even small rule changes can shift the numbers a little, so it might be worth a quick check if you like to compare tables.
Do Players Win Every Time the Dealer Busts?
Not always. You only win against a dealer bust if your hand is still active. If you went over 21 earlier in the round, your hand has already lost, even if the dealer busts later.
If you are under 21 when the dealer busts, your bet is settled as a standard win for that table. What happens to other players does not affect your payout. The only comparison that matters is your hand against the dealer’s final result.
Can You Predict When a Dealer Will Bust?
You can estimate, but you cannot forecast a single round. Upcards provide context, not certainty. A 4, 5 or 6 increases the dealer’s bust risk, while a 10 or Ace reduces it, but each hand is still a separate event.
Online games use Random Number Generators (RNGs) to reshuffle each round, and live dealer tables use multiple decks and standard shuffling, so outcomes remain independent. Techniques such as card counting are not supported online and are not permitted by operators. UK Gambling Commission (UKGC)-licensed sites must keep games fair and publish clear rules, so you can rely on the stated mechanics for each table.
