Double Exposure blackjack rules

The Double Exposure variant of blackjack is one of a kind, allowing players to view both of the dealer’s first two cards before playing out their own hand. While traditional blackjack games reveal only one dealer card, in Double Exposure the player is able to make his or her decisions already knowing the two-card dealer total.

How to play Double Exposure blackjack

The following set of rules are carved in stone in a game of Double Exposure:

  • The dealer wins if a dealer and player hand ties*
  • Blackjack, like all other winning hands, pay out at 1:1
  • A hand automatically stands when the total card value is 21

*If the dealer and player both have blackjack, depending on the rules, the result may be considered a player win or a push (get your money back). More often than not, such a scenario is considered a player win.

Also note that you will lose your hand if you and the dealer both have 21, totalled any other way besides a blackjack hand, as this is a tie (for example, a hand made up of a Seven, Eight and Six).

The following list of rules are those which can change depending on the version of Double Exposure being played:

  • Whether the dealer stands or draws on a soft 17 (it is better for the player if the dealer stands on all 17s)
  • When you can double down, and in what situations you can split your cards
  • Minimum and maximum bets allowed per hand

Dealt almost exactly like a traditional hole-card (American) game of blackjack, all players receive one face up card (from the dealer’s left to right), the dealer receives a face up card, each player receives his or her second card, and then the dealer receives his or her second card – however this card is also dealt face up.

All players now know the dealer’s two-card total. Play out the game following basic blackjack strategy first and foremost. However, your strategy will need to differ from basic strategy when you are placed in a scenario in which you would typically stand, but are now forced to hit due to the dealer’s total.

Let’s look at some examples:

1. You are playing two hands, simultaneously (something which the Double Exposure games available at our recommended gambling sites offer). For one hand you are dealt a King and a Seven, and your other hand shows an Ace and a Five. The dealer is showing a Jack and an Eight.

With the Ace/Five hand follow basic strategy, which would suggest to hit. You can access the Wizard of Odds Double Exposure blackjack strategy charts here if you are keen to follow to a tee the exact recommendations, based on probability, of how to play out your hand.

2. If the dealer is showing a two-card total of 20 and you are also showing a two-card total of 20, then all you can do is hit and hope for an Ace, as all other results will see you lose through either a bust or having a tied hand with the dealer.

The more flexible the rules are for splitting and doubling down the better. The online variant of Double Exposure is typically played with a six-card deck, but here are no hard and fast rules, and you may come across versions with slightly altered laws in regards to how many decks are used, and when and when you cannot double and split, as alluded to above.

The game’s house edge

Net Entertainment’s Double Exposure – the game we recommend to play, which is available at www.GdayCasino.com – has a 99.33 per cent theoretical return (equivalent to a 0.67 per cent house edge). It allows the player to double down after splitting, pays out 1:1 on tied player and dealer blackjack hands, utilises six decks and forces the dealer to stand on all 17s (and draw to 16).

This is how some alterable rules affect the Double Exposure house edge:

  • Dealer standing on a soft 17 increases the house edge by 0.39 per cent.
  • Allowing a double down after a split increases the house edge by 0.32 per cent.
  • A tied blackjack which is considered a win (rather than a push) boosts the house edge by 0.22 per cent.
  • Allowing the player to split only once reduces the house edge by 0.71 per cent.
  • If doubling is only allowed when your two-card total is 9-11, the house edge is reduced by 1.04 per cent.

Double Exposure is an entertaining and valuable offshoot of blackjack, and even though we typically recommend to steer clear of blackjack variations which do not pay out 3:2 on genuine blackjack hands, because you are privy to both of the dealer’s cards in this game, the 1:1 payout for blackjack is a concession we are happy to make.

The Internet gambling websites recommended above are legally accessible to all Australian residents, AUD currency is accepted, and popular and secure banking methods are provided, such as credit and debit cards, e-wallets, pre-paid cards and vouchers and direct bank/wire transfer systems.

As always, set yourself a time and expenditure limit when gambling, and enjoy the online gaming experience.
