21 Duel Blackjack Review

Screen shots of the games


21 Duel Blackjack is one of many variants on the game of Blackjack. This one is specifically offered at Playtech casinos online. I don’t think it’s offered at any offline casinos.

21 Duel Blackjack is like a cross between standard Blackjack and Texas Hold ‘Em poker due to the use of shared community cards. The Player places an Ante wager and is dealt 2 cards, 1 face down and 1 face up, 2 community cards are dealt face up and 2 dealer cards are dealt face down. The player can then choose to Fold, losing their Ante bet, or to select one of the two community cards to play with which will cost another bet equal to the Ante. Finally the player has to choose whether to stand on the two cards they have (their face-up card and their selected community card) or to Hit and reveal their face down card.

After the player’s acted the dealer will turn over one of their cards and select one of the community cards for their hand using the following rules and selecting that hand which is highest in the table;

2 Card Score Possible Hand Combinations
21 Blackjack (an Ace and a Ten)
20 A9, TT
19 A8, T9
11 92, 83, 74, 65
10 82, 73, 64, 55
9 72, 63, 54
18 99, T8, A7
17 98, T7, A6
Soft 16 A5
Soft 15 A4
Soft 14 A3
Soft 13 A2
Soft 12 AA
8 62, 53, 44
7 52, 43
6 42, 33
5 32
12 T2, 93, 84, 75, 66
13 T3, 94, 85, 67
14 T4, 95, 86, 77
15 T5, 96, 78
16 T6, 97, 88
4 22

As an example of the above, if the dealer had a 9 showing and the two community cards were a 9 and a 2 the dealer would select 2 as that forms an 11 which is higher in the table than 18.

Finally if the combined total of the dealer’s card and their community card is less than 17, the dealer will turn over their final card and add it to their hand.

Once the dealer has played their hand the results are decided like a regular Blackjack game, only a hand of Blackjack is counted as 21 so it can be pushed by other 21s and the dealer has to get 13 or higher to qualify.

If the player wins the hand and the dealer qualifies then both bets are paid at 1 to 1. If the player wins the hand and the dealer does not qualify the Ante bet is paid at 1 to 1 and the other bet (placed to get a community card) is returned. Otherwise the player loses both bets.

The House Edge for 21 Duel Blackjack, when playing using optimal strategy, is 1.62%. You should not play the 2UP side bet as this has a far higher House Edge and as such will cost you far more money to play.
