What is an Ace in Blackjack?

The most popular casino card game in the world is also one of the most misunderstood. The goal of Blackjack isn’t to get as close to 21 as possible; it’s to get closer to 21 than the dealer. And the best thing about Blackjack? The game itself takes a matter of minutes to learn; with cards 2-10 being worth their face value in points and face cards all being worth 10 points.

Then there’s the Ace, the most dynamic and powerful card in ace blackjack. Why? Well, we’re going to tell you. So, grab a drink, get comfortable, and come along with us as we break down the infamous “Ace” in blackjack.

What Is an Ace in Blackjack?

There are few cards in any card game as important as the blackjack ace. The Ace in Blackjack stands out from the other cards for 2 reasons:

  1. Ace worth in blackjack can either be worth 1 or 11 points.
  2. The only way to get what’s called a “true blackjack” is by having an ace in blackjack worth either a 10 or face card (A + 10 =21).

The Ace is flexible, meaning, in most cases, you can choose whether it’s worth 1 point or 11.

How Much Is an Ace Worth in Blackjack?

As mentioned above, the Ace can be worth 1 or 11 points. It’s the only card in ace blackjack that has what is referred to as having “mathematical flexibility.” Because of this, the player can choose the ace in blackjack worth.

Is an Ace Worth 1 or 11 in Blackjack?.

So, is a blackjack ace 1 or 11? There’s only one rule when it comes to whether an Ace is worth 1 or 11 points. An ace in ace blackjack can only be worth 11 points if the total amount of the cards in a player’s hand is less than 21. We’ll break it down a bit further down.

Can the Ace’s Value Change During a Hand?

Because of the mathematical flexibility of an Ace, it can switch its value between 1 point or 11 in a single hand—the ace value in blackjack being dependent upon the total number of points of the hand. Here’s how it works:

  • If the player only has 2 cards, the Ace is automatically assumed to be worth 11 points. For example, A + 8 = 19.
  • If the player decides to hit (take an additional card), the Ace can turn into 1 point to avoid going over 21 total points. For example, A + 8 + 3 = 13 instead of A + 8 + 3 = 22, which would lead to a bust and the automatic loss of the hand.

Whether your Ace is a 1 or 11 greatly depends on the other cards you have in your hand.

How Aces Work in Blackjack Hands

If it’s the start of a hand, and you only have 2 cards, always remember these rules:

  • If you have a single Ace and another card, the Ace is always worth 11 points. (A + 2 = 13) or (A + 9 = 20).
  • If you “hit” and take another card, the Ace can either be a 1 or 11, depending on the total ace value in blackjack (A + 8 + 10 = 19) or (A + 2 + 2 = 15). It really just depends on whether you want to hit again.
  • If you hit and take another card and the total point number becomes more than 21, the Ace automatically becomes worth 1 point to keep the total under 21.

To see this in action, be sure to play free online blackjack games.

How to Play a Single Ace

It’s always a good general rule to assume the dealer’s face-down card is a 10. Because of this, there are several rules to playing a single Ace:

  • If you have just 2 cards below A + 6, the general rule is to hit. As you may receive a low card. If you receive a card worth 10 points, your hand becomes a 17.
  • If you have any 2 cards above A + 7, the general rule is to stand.

These are just a couple of basic rules any beginner should follow. For expert players, read our blog for additional articles on ace blackjack.

What It Means to Be Dealt Two Aces

Being dealt 2 aces in blackjack is always worth 12 points. It’s a very powerful hand because it gives you several options:

  • Hit and take another card. In which case, you can use the cards as a 1 and an 11 or two 1s.
  • The most recommended way to play 2 Aces is to split them.

Here’s how to split 2 aces in blackjack and what that means.

When Should You Split Aces?

Splitting 2 aces in blackjack is always recommended. What splitting Aces means:

  • The dealer turns each Ace into an individual hand.
  • You have to place the same bet on the second Ace as you have on the first Ace.
  • The dealer then treats each Ace as a separate hand. They will give you another card for each Ace.

In most places, you will only ever receive 1 additional card for each Ace. This is something important to keep in mind.

Doubling Down with an Ace

Doubling down means you have to double your bet and are forced to receive only 1 additional card. Keep in mind:

  • It’s recommended when you have A + 6 and the dealer has a 5 showing.
  • Avoid doubling if the dealer has 7 or more points showing.

Most casinos do not allow you to double down after you have already hit a hand or after you have split your hand. Be sure to ask the specific rules before playing.

Splitting Aces – Best Practices

As we’ve mentioned, it’s always best to split Aces. This will increase your chances of an ace blackjack. The only time it’s not recommended is if you’ve bet more than your normal amount on the first hand and don’t have the money to double that bet.

Dealer’s Ace in Blackjack

The blackjack dealer ace rules say that a dealer must always check for a blackjack ace. If they have a blackjack, you lose. If not, the game resumes in the normal fashion. Remember, the Ace for the dealer follows the same 1 or 11 points. This actually happens more than you think. Play Blackjack Games Online and see for yourself.

Should You Take Insurance?

If the dealer has an Ace showing, you can buy insurance. This will help prevent losing all of the money you bet. You will need to spend half of your original bet. If the dealer has blackjack, you are paid double the insurance bet and lose your original bet, causing you to break even. If there is no blackjack ace, you lose the insurance bet. It is generally not recommended to buy insurance.

If the dealer has an ace, use caution and avoid doubling down. You’ll want to play carefully as the dealer now has flexibility and is more likely to end up with a better hand.
