Doubling down is an exciting move to make in blackjack – and profitable if you get it right. You can double your bet in the middle of a hand, after which you only receive one more card.
Blackjack is a highly popular casino game with gamblers around the world for its simple rules and the possibility to get the advantage over the house with a proper strategy. One of the moves that can change the outcome of a round is doubling down which allows you to double your initial to get the third card for a chance to create a better hand and win a doubled prize. This option is not available in all Blackjack variants, so it is always recommendable to check out the rules of the game you choose to play.
Doubling down is an additional bet that can be risky because you can lose a double wager on a hand. That’s why it is important to know when and how to double down to make the most of the game.
Double Down Rules
Once you find a casino and a Blackjack variant that allows doubling down, you should check out the rules of such a bet. In most cases, you will be allowed to double down on your first two cards while some casinos may allow you to double down on a Blackjack hand. Another situation in which you can double down is after splitting two cards of the same value while at some casinos you can use the double down option only on hard 9, hard 10 or hard 11.
If you want to use this option, you should inform the dealer about your move by placing the same amount of chips right next to your original wager. In case you want to double down on a pair, it is important to inform the dealer that you want to double down and not to split the pair. If you play the game at a land-based casino, you have to say “double down” before you place an additional bet. When playing online, all you have to do is to push the Double Down button and the bet will be added instantly.
The doubling down ends when the dealer places a new card across your cards dealt in the first hand. After you have doubled down, you cannot make any additional moves and your total hand consists of the three cards you have been dealt. At some brick-and-mortar casinos, you may be allowed to double down with an additional bet that is less than your original wager.
Double Down Strategy
There are a few situations in which you should consider doubling down. One of them is when you have hard 9 and the dealer has a low card between 2 and 6. Keep in mind that this applies only to a hand with no Aces, meaning that you can have either a combination of 2 and 7, 3 and 6 or 4 and 5. If you have been dealt a soft 9, the best option is to stand.
Another situation where doubling down is recommendable is when the dealer has a low card from 2 to 6 and you have a soft 16 to 18. If you have a combination of an Ace and 5, 6 or 7, it is preferable to double down. A hand with an Ace and a lower card between 2 and 4 requires hitting as this move can provide you with a chance to create a higher value hand.
Finally, when the dealer gets lower cards and you have been dealt a hard 10 or 11 with no Aces, you should double down as you can easily win with such a hand.
Advantages of Doubling Down
Doubling down is a risky move as it ends the round and leaves you with no additional moves left, but with an extra card you can beat the dealer and win a double payout. It is more suitable for experienced players who can combine this move with one of card counting techniques to get the edge over the house.
One of the best and most exciting options available in blackjack is when we have the opportunity to double down on a bet. As a ‘twice the risk, twice the reward’ option, it has the potential to net us a sizeable return, if we know how and when to properly employ such a tactic. As explained on our terminology page, to double is to place another wager on your hand, equal to the amount of your initial bet, in exchange for only one additional card, and the obligation to stand after that one card is dealt.
For example, if you have been dealt a Six and a Four (a total value of 10), you may choose to double your original wager of $100, as drawing a card valued from seven to 11 is a strong possibility and will stand you in good stead to win the hand. If you do win the hand, instead of receiving a $100 profit if you did not double, you will net a return of $200.

Double Down Blackjack Split
Doubling is an essential tactic, and if used correctly, helps to lower the casino’s house edge. A knowledgeable player should know when to employ this move for an advantage in the long run, but the decision needs to be carefully considered before commitment, based on a the following important factors:
- The total points value of your current hand
- The dealer’s up-card
- The house rules and edge
- The version of blackjack being played
If you are playing a game with eight decks and you can double on any total, the house edge is 0.55%. If you can double after splitting, this reduces the house edge by 0.13%, but if you can double only on totals of 10 and 11, this increases the house edge by 0.21%. And obviously we want the lowest house edge possible.
Mastering basic blackjack strategies is key to winning. Here are some guidelines worthwhile remembering in order to maximise our chances and avoid unfavourable odds when opting to double:
Double Down Blackjack Meaning
Take Advantage of 9, 10 & 11 Totals
The best hands to double down on are considered to be those with a value of nine, 10 or 11. We already have the ideal hand to hit on and end with a strong total with just one additional card. If you find yourself dealt a hand with these totals, consider doubling down to maximise your winning payout. There will always be a risk present in every decision you make, but the key to winning more games than losing is to take advantage of an edge while you have it. If you are hesitant to double down because of the size of the bet and your potential loss, you might be playing at a table with too high stakes.
Don’t Split Fives, Go For The High Five: A common tactic for players who find themselves with low pocket pair hands such as Deuces or Treys is to split them and improve their chances of winning with two separate hands, which is fine. But if you find yourself with a pair of Fives, refrain from splitting and consider doubling. A total of 10 points is a strong position to be in (as explained above), so with a pair of Fives and roughly a 24% chance of drawing a card valued at 10 points on the next hit (to give you a total of 20), doubling is in your best interests. You also have a solid chance of drawing an Eight, Nine or Ace, resulting in favourably high hands of 18, 19, or 21.
The Rule of 9
When Do You Double Down On Blackjack
The ‘Rule of 9’ is an established guideline regarding when and when not to double if you are dealt a soft hand (a hand with an Ace). Knowing when to double with a soft hand is crucial, so it is worthwhile understanding the rule’s instructions which explain how to maximise our chances of winning. As always, these are recommendations and you don’t have to double just because these rules say so.
The ‘Rule of 9’ works as follows: if you hold a soft hand, add the value of the dealer’s up-card with the value of your non-Ace card. If the total value is greater than nine, it is suggested to double down. If the total value is less than nine, proceed to hit instead.
For example, if the dealer’s up-card is a Four and your hand contains an Ace and a Seven, you should double because the total sum would be 11. In contrast, if the dealer’s up-card is a Five and you hold is an Ace and a 3, you should hit, as the sum, according to the rule, is eight. There are a few exceptions to this rule: never double down if the dealer’s up-card is above Seven, as they are in a strong position to beat you. If the dealer is showing a Deuce, don’t double either as the odds favour the dealer. Also, when the dealer’s up-card is a Five or Six, you should double down with a hand of an Ace and a Deuce through to a Six, as you are in the stronger position.

Be Mindful of the Dealer’s Up-Card
It may seem like common sense, but plenty of players often forget to keep the dealer’s up-card in mind before opting to double down. All of the above tactics should be dependent on the dealer’s up-card, and while it’s good to be aggressive, it can be unwise to double with a soft hand if your dealer has a Nine or Ten showing. The worst cards for the dealer are up-cards of a Deuce through to a Six because those cards give the dealer the highest chance of busting, and this is when we should pounce and double down. Dealer up-cards of Five and Six give their hand the highest chance of busting at roughly 42%.
Here are the most commonly recommended hands to double down on, taking in to consideration the dealer’s up-card:

If you are dealt an Ace with a Deuce through to a Seven, this leaves us in a relatively strong position to double (depending on the dealer’s up-card, as specified in the table). If your soft hand is an Ace and an Eight or Nine, then doubling is not favourable; standing is your best bet.
Being dealt an Ace and a Six or Seven is the ideal hand to double down on. Many people may opt to stand with a soft total of 17 or 18 which is fine, but doubling is often advised. As the table suggests, your decision needs to be dependent on the dealer’s up-card. If you do opt to double with a soft 17/18, you have a strong chance of receiving a card valued at 10 (giving you a hard total of 17 or 18) which leaves you in the position you began in, just with the chance to win double the cash. If you are dealt an Ace, Deuce or Trey, you now hold an even stronger total of either 18, 19, 20, or 19, 20 or 21. If you are dealt a Four on the soft-17 hand, that will also leave you with an unbeatable 21. The point is to take advantage of strong starting soft hands, because of the unique value the Ace holds.
Know Which Variant You’re Playing
American blackjack (unlike American Roulette) has more favourable odds for the player, so where possible, play American versions of the game.
American rules are as follows:
– You are not restricted when doubling down; you can have a hand with any value and choose to double.
– You can also surrender at any time, and the dealer must stand on a soft-17.
European blackjack has the following rules:
– When offered the chance to double, you may only do so if your hand totals nine, 10 or 11.
– The dealer must hit on soft-17, and you cannot surrender.
