An Introduction

In many ways, 21 Duel Blackjack players will find that the gameplay here is much simpler than a traditional game of blackjack, in that the options are streamlined. There is no option to split, to double down, and no getting a natural blackjack. Let’s look at the basics.

With the same familiar objectives as blackjack, yet with the addition of new elements and the lack of many of the traditional ones, 21 Duel Blackjack will offer gaming enthusiasts in Canada an exciting and streamlined real cash online gambling experience.

Same As It Ever Was

The basic idea in a 21 Duel Blackjack game is the same as in the traditional version of blackjack. It is a game of the player versus the dealer. Each is attempting to complete a hand with the highest value possible, without exceeding 21, in order to beat the other’s hand of a (hopefully) lower value. Card values and scoring is the same here as it is in traditional blackjack, where Aces can count for a value of either 11 or 1. This should all sound very familiar so far!

What’s The Deal?

The player and the dealer are both dealt two cards. For the player, one is face up and one is face down. For the dealer, both cards are dealt face down. Next, two face up cards are dealt in the middle of the table. These are communal cards that all players and the dealer can choose from to complete their hands.

Stages of Betting

There are three stages of betting in a 21 Duel Blackjack game. Before cards are dealt, the player makes an initial ante bet. Also at this point, a second, optional bet can be placed, called a 2 Up bet (more on this further down). Once cards have been dealt, the player decides if they are going to fold or continue. If they continue, they must make another bet and choose from one of the community cards to add to their hand. This bet must be equal to the initial ante bet.


Now it’s the dealer’s turn. They reveal one of their two face down cards, and choose from one of the two community cards to add to their hand. Note: the dealer is allowed to choose the same card as the player chose from the face up community cards. If the dealer’s hand has a value of 17 or greater, they must stand. If they have a hand lower than 17, they may choose to hit by turning over their other face down card.

At this point, if the dealer has a hand with a value of 12 or less, they do not qualify. The player wins the original ante bet, while the second bet is pushed (no money is lost or won for either player or dealer). If the dealer has a hand of 13 or greater, the two hands are compared, and the highest hand (without going over 21) wins.

Blackjack Vs. 21 Duel Blackjack

Let’s take a closer look at the ways a game of 21 Duel Blackjack differs from your basic game of online blackjack in Canada.

The Hole Cards

Players will note that the first big difference right off the bat is the dealing of the cards. In traditional blackjack, both of your cards are dealt face up. The dealer however has one card face down, which is called a “hole card" and one face up. In a game of online 21 Duel Blackjack, both of the dealer’s cards are face down, and the player has one hole card.

Building A Community

Next is the addition of the face up community cards, which do not exist at all in standard blackjack. This allows both the dealer and player to see in part what the other’s hand could look like in a way that is unique to 21 Duel Blackjack.

An Exciting Twist

An Exciting Twist

Unlike normal blackjack, the 21 Duel variation has the exciting addition of an optional side bet. This bet, called a 2 Up, is a separate second bet that can be made at the beginning of the hand (before cards are dealt), as to the outcome of the face up cards.

Betting and Odds

There are three stages of betting in 21 Duel Blackjack: the ante, an optional 2 Up bet, and the final bet. Let’s look closer at these three stages.

The Ante

The ante is the initial bet made by the player. This bet is made before any cards are dealt. Like most other games, there will be a minimum and a maximum bet amount.

The 2 Up

The 2 Up is an optional side bet players can make in 21 Duel Blackjack. This bet is also made before cards are dealt. The objective of the 2 Up bet is to see if the face up card will match with one or both of the two face up community cards. If one of the cards matches another, the player wins the bet at a 3 to 1 payout. If all three cards match, the payout is 20 to 1! The 2 Up bet can be won regardless as to who wins the actual hand.

The Final Bet

This is the bet the player makes if they wish to continue after seeing their hand. It is the only other bet that can be made in the hand, and it must equal the value of the initial ante.

The ante and the final bet are won together with a winning hand. However, in the event of the dealer disqualifying (with a hand under 13), the player will in the initial ante, while the final bet pushes. These two bets both pay out at even money, while the side bet again pays out at 3 to 1 or 20 to 1, depending on the above-mentioned outcomes. The house edge in 21 Duel Blackjack is 3.08%.

Strategy for Beginners

Should I Stay Or Should I Go?

One of the biggest choices in any game of blackjack is whether to hit or to stand. In a 21 Duel Blackjack game, a good rule of thumb is to stand on a hand with a value of 17 or greater, and to hit on a hand with a value under 17. That is unless you have a “soft 17,” which is a hand with a value of 17 that utilizes an Ace, a card that can have a value of either 1 or 11. This is especially an instance in which to hit if the Ace in question is one of the community cards.

Know When To Fold ‘Em

It’s never fun to fold. There are just some cases when it is downright foolish not to though. If you have a face up card of an A, and the two community cards are also Aces, fold! A hand of double Aces is considered the worst hand you can hold in blackjack, and normally, you would want to split them. That’s not an option in a 21 Duel Blackjack game though. Not only that, but you can only hit once! In general, those two factors are essential to have in mind. Always consider the possible strength of your hand based on the choice of community cards in front of you, and then consider the general probability of what you might find if you hit. Generally speaking, a player with a low face up card (under 7) paired with the choice of community cards that will only get them an initial (pre-hit) hand of a low teen should consider folding.

How exactly do you play a game?

21 Duel Blackjack is played against a dealer. The objective is to have a hand that is a greater value than the dealer’s hand. The highest valued hand you can have is 21. Anything over that busts, losing that hand. An initial bet is made before cards are dealt, and then is met again if the player chooses to continue with a hand. If the player wins, they receive money equal to the ante, as well as retaining their original bet.

Does the table layout and betting work the same way as other blackjack games?

Yes and no. As in traditional blackjack, an initial bet is made before the players and dealer are dealt two cards. There is an addition of two face up community cards in the middle of the table. A one-time second bet is required to continue. An optional side bet, called a 2 Up, can be made as well, before cards are dealt.

How popular is 21 Duel Blackjack online?

It is not yet as popular as other forms of blackjack are in Canada, but its popularity is rising. Many real money online casinos feature it on their sites.

Is the game much different from other blackjack games?

It is identical to regular blackjack in its objective to beat the dealer’s hand by having a hand of higher value, up to but not exceeding 21. How the cards are dealt, the absence of options such as splitting and doubling down, and the addition of an optional side bet are the main ways that it differs from traditional blackjack.

What are the odds like in 21 Duel Blackjack?

The house edge in 21 Duel Blackjack is 3.08%.

Can you use any systems when playing?

While there are several systems that circulate gambling forums, 21 Duel Blackjack is a game of chance. So there is no sure-fire way to ensure victory every time you play.
