How to Deal and Play 21 Duel Blackjack Online

Just like the regular online blackjack game, your only aim is to beat the dealer with a hand that’s bigger and better, without going bust. Your maximum points total is 21, otherwise you go bust. As 21 Duel Blackjack is one of our multi-hand casino games online, you can play several hands at a time and each has its own wager – and you can use most of the standard actions is blackjack online, with the exception of Split, Surrender, Double and Insurance, as these don’t make sense with the extra 21 Duel Blackjack bets in action. Actions you can take advantage of include:

  • Hit – click this to claim another card and add up your points total before deciding whether to hit again
  • Fold – you end your round by surrendering your hand (a losing bet)

  • Stand – keep the cards you have

Your 21 Duel Blackjack 2-Up Bet

This bet is available during every round and costs an additional wager. The 2-Up bet is a bet on your own first card and the community cards and you are betting on whether a pair or 3x matching cards can be made. Get the bet right and you will be paid out at 3-1 for the pair and at a giant 20-1 for three matching cards – this is one of the biggest payouts available on any online blackjack game that does not have a progressive jackpot attached. On 21 Duel Blackjack, the blackjack hand pays out at even money.
