Can You Double Down if You Have Blackjack?

In blackjack, doubling down is when you double your original bet after receiving your first two cards. For example, let’s say you bet $5 and are dealt a 9 and a 3.

You could then double down, betting $10. If the next card is a 5, you would have a total of 21 (9+3+5), which is a blackjack.

PRO TIP:In Blackjack, if you have a hand of 21 (an Ace and a ten-value card) on your first two cards, it is not possible to double down as this would be considered ‘overplaying’.

The option to double down is only available on the first two cards dealt. After you take a hit (receive another card), you can’t double down.

And, you can’t double down if you already have a blackjack.

So, can you double down if you have blackjack? No, because as we just mentioned, you can only double down on the first two cards dealt. Once you receive more cards or have blackjack, the option to double down is no longer available.
