Rules and Play

21 Duel Blackjack is a variation offered at Playtech casinos. At the start of the hand, 6 cards are dealt — 2 player cards, 2 dealer cards, and 2 communal cards. The player forms a blackjack hand using their upcard and 1 of the 2 communal cards. The player has options to double their bet or fold the hand. The dealer follows specific rules to form their hand, known as the “house way.”

Strategy

Until you get a feel for the game, it’s recommended to use the optimal strategy calculator. The house edge per unit wagered is ~1.65% when following optimal guidelines.

  • Fold on specific hands with player upcard 2-7 and communal card 10 or A.
  • Choose the communal card to form the highest two-card rank based on the strategy list.
  • Generally hit 16 or less and stand on 17 or greater. There are exceptions, e.g., hit soft 17 if one communal card is an ace.
House Edge 3.08% (per initial bet), 1.62% (per unit wagered)
Variance and Bet Size Standard deviation per initial bet: 1.72, Standard deviation per unit wagered: 1.25

Note: The game’s house edge and variance are higher than other Playtech blackjack games, making it less suitable for bonus play.
