21 Duel Blackjack is played with 6 decks in both single and multi-hand mode. Even though the main object of the game and the card values match perfectly the ones of classic blackjack, everything else is quite modified and unique. The table features 3 “Ante” areas where you can place the desired bets starting from £1 going up to £300. When deciding on the amount keep in mind that as the gameplay continues you’ll be required to place a second bet in the same initial volume in order to finish the round.

After all bets have been placed, the player is dealt one face-up and one face-down card including two face-up communal cards right above. Step one is to decide whether you would fold – give up your hand and lose the initial bet or you would continue playing. If you go for the second option, select which of the communal cards would make a better combination with your own face-up card and click on the right or the left card button. Your choice could automatically form a 21 result and will add that second bet we discussed previously. From here on, you can either hit or stand while the dealer chooses a communal card according to a special set or rules featured in the info game section.

Payout wise, the differences from classic blackjack keep on piling up as a three card 21 result is considered equal to a classic blackjack and both pay 1:1 on the Ante and the additional wager. To make it even more exciting, the game offers a side bet option. It is right next to the ante section and lets you bet whether the two communal cards and your first face up card will form a pair or 3 of a kind paying respectively 3:1 and 20:1.
