But the game is played with all cards face up. Differences Between Face Up 21 and Blackjackįace Up 21’s objective remains the same as blackjack: beat the dealer, and get as close to 21 as possible, without exceeding that number. As such, the house edge is greater than conventional blackjack, but if you happen to find Face Up 21 at your chosen casino, you can come out of a game with a good return should you adjust your strategy and play properly. Naturally, this variant introduces other rule changes to compensate for the tactical shake-up and favour the dealer. The conventions of Face Up 21 change our strategy dramatically card counting and hole-card guessing are no longer factors to worry about: if you don’t like what you see, play accordingly. Face Up 21, also known as Double Exposure or Dealer Disclosure, is a version of blackjack where both the dealer and player’s cards are dealt face-up, giving players double the information to play out their hands.
