21 Duel Blackjack is played with 6 decks, which are shuffled after each hand.

How the Game Works

To start a hand, you will first place your ante bet and click deal. Unlike in classic Blackjack where the player and dealer are both dealt two cards, in 21 Duel Blackjack the dealer hands out a total of 6 cards

  • 2 for the player – 1 face-up and 1 face-down
  • 2 for the dealer – both cards are face-down
  • 2 community cards

The player goes first, and you can choose either the right or left community card to pair with your face-up card. If you still want to hit after collecting your card, the face-down card will be revealed. Then it’s the dealers turn to play.

The 2 Up side bet is a way to win some extra money, regardless of the outcome of your hand. The bet pays out if, together with the communal card of your choice, you’ll have two or three of a kind. This can lead to a tough decision if, by choosing the matching card, you might be giving yourself a worse hand for the Blackjack game.


While the objective of 21 Duel Blackjack is the same as the traditional Blackjack game, the rules are pretty unique.

  • The player wins by having a point total that is higher than the dealers but doesn’t exceed 21.
  • The dealer must hit on 16 and stand on 17
  • In addition to the Ante bet, you must place a matching bet on the communal card of your choice
  • Three is the maximum number of cards in a hand
  • Blackjack pays out 1:1
  • The 2 Up side bet can pay out as up to 20:1
