How to play Blackjack - Double Down Tips

What is doubling down? It’s when a player has a strong two carded total when the dealer shows a weak up card such as 2, 3, 4 or 5. The player matches his original bet in a bid to take advantage of the dealer potential vulnerability to busting.

Double Down Rules & Strategy

So when do you double down?
It's easy just double down on the following hands:

You Hold Dealer Holds
9 3, 4, 5 or 6
10 Anything but a 10 or an Ace
11 Anything but an Ace
A-2 5 or 6
A-3 5 or 6
A-4 4, 5 or 6
A-5 4, 5 or 6
A-6 3, 4, 5 or 6
A-7 3, 4, 5 or 6

Just remember that you’re betting on the dealer going bust because of the number of potential cards he will have to deal himself due to the low up card. The greater the number of cards he has to deal, the greater the chance he will go over 21 and you will win.

Doubling up enables you to double your money in an advantageous position but it will cost you twice your bet so choose your hands well to minimise your losses.

While playing you can also use the alternative of double blackjack in a face down game by tossing the two cards face-up on the table in front of your bet. You can add an additional bet to the betting circle by placing the additional bet adjacent to the original bet, not on top of it, while choosing a double down option. However, in the face down game, the dealer usually tucks the additional card face down under your bet, to be revealed later.

Players are allowed to double down in blackjack for any amount up to the original bet amount, so you could also double down for less. However, if the correct play is to double down, you should always double for the full amount if possible.
