Introducing Duel Blackjack

From the back-street and rustic suburbs of 17th century France to the silver screen, blackjack has made an incredible transformation from a simple parlour game to an iconic casino experience. It has now also become popularised online, with gaming software companies such as Playtech playing a pivotal role in creating new and innovative blackjack formats for contemporary players. This has led to ’21 Duel Blackjack’ being created for the Winner Casino and this format borrows heavily from traditional gameplay elements and aspects of stud poker. If you enjoy variety at the tables, our roulette bonus guide rounds up more table games worth trying.

How do you Play 21 Dual Blackjack?

This unusual blackjack variant is unique in many respects, not least because it is considerably different when compared with the traditional format of the game. Most use the original game as a template, before adding new elements to create a refreshed and innovative version. To begin with, all hands with a value of 21 are equal (whether they consist of a natural blackjack of ten or a picture card and an ace) or not. The game also includes community cards, borrowing a template usually used by poker formats.

As usual, the game starts with an ante wager, after which time players are dealt two cards (one which is visible and one which is face down). Neither of the dealer’s cards will be visible at the beginning of the game, while two community cards will also be dealt and placed face-up in the middle of the table. Players who fold will forfeit their ante wager, while those who wish to proceed select one of the community cards to build their hand. Once you do this, an additional wager will be made that is equal in value to the ante bet. You can then stand with this three card hand, or hit and turn your face-down card over.

Is this Game Format right for you?

All players should end up with a two or three card hand, and the winner will be determined in the usual manner. Although all hands to the value of 21 are considered equal, there may be further subtle variations that alter this depending on the rules of the individual operator. In some instances, you may lose both wagers if the dealer’s hand is more than 12 and higher than the value of your cards, while you will win both bets if these circumstances are reversed. This reflects a slightly convoluted set of rules and guidelines, and it is certainly more suited to experienced blackjack players than those who are relative novices.
