Double Attack Blackjack vs Traditional Blackjack

Double Attack Blackjack

Double Attack Blackjack is a blackjack variation made from Spanish 21. Double Attack Blackjack pays even money on the player getting a blackjack hand but what makes this blackjack game interesting is the fact that the player has the option to double their wager after seeing the dealers up card, this is where the Double Attack comes from.

As in Spanish 21, Double Attack Blackjack also offers its players the opportunity to place a side bet the side bet is called Bust It and works in a similar way to Spanish 21’s Super Bonus. Bust it pays the player fixed odds based on the player picking getting the dealers third card correct. The odds are as follows:


  • Third card is a ten. Pays off 3/1
  • Third card is a nine. Pays off 6/1
  • Third card is an eight. Pays off 8/1
  • Third card is a seven. Pays off 10/1
  • Third card is a six. Pays off 15/1

Additional side bet wagers are accepted on certain sequences of the dealer’s cards, for example:

  • The eight is the same colour. Pays off 50/1
  • The eight is the same suit. Pays off 200/1

As well as estimating what the dealers third card may be. Players can also wager on the amount of cards the dealer will pull before going bust. Odds are as follows:

  • Dealer busts with 3-4 cards. Pays off 2/1
  • Dealer busts with 5 cards. Pays off 4/1
  • Dealer busts with 6 cards. Pays off 12/1
  • Dealer busts with 7 cards. Pays off 50/1
  • Dealer busts with 8 cards. Pays off 250/1

Double Attack Blackjack uses 8 decks of regular cards with 4 tens removed, the dealer stands on a soft 17, the dealer has the option to peek for blackjack should the player decide on taking insurance, the insurance pays out at 5/2. The player can double after splitting, splitting aces doesn’t result in the player receiving one card and all cards except aces can be split up to four times.

There are other blackjack variants which are not played online such as French and German blackjack the French version called, Vingt-et-un which is French for 21 and the German version which is called Siebzehn und Vier, German for 17 and 4 does not allow the splitting of cards and the ace only counts for 11 however getting two aces amounts to the player or banker getting 21. The British version of blackjack or 21 is called Pontoon. Pontoon is played with regular 52 card decks and uses terms such as twist and stick rather than hit and stand.
