Established 2008

21 Dukes

21 Dukes Casino became what it is today in 2008 but originally launched back in 1999 in another form. It is owned by Blacknote Entertainment Group, an operator with lots of experience in the online casino industry.

Blacknote Entertainment Group owns other online casinos so you can expect the same treatment from 21 Dukes Casino as you would from its sister casinos. It is also fully licensed by the Government of Curacao. The site is available in Spanish and French as well as English. However, it is not available to US players.

Promotions Fine Print

At 21 Dukes Casino, new players receive 25 spins absolutely free with no deposit required. The maximum amount that can be withdrawn from these free spins is €100, only when the winnings are first wagered at least 20x. Additionally, the player must have made at least one deposit. Not only must the free spins be used within 7 days after receiving them, but the wagering requirement of the winnings must be met as well. Otherwise, the free spins and winnings will be forfeited.

Similarly to the free spins, bonus funds also expire within 7 days after receiving them, unless the wagering requirements have been met. Wagering contributions differ between every game and the maximum spin/bet that can be placed with bonus funds is €5. The contribution percentages also depend on whether the bonus is a deposit bonus or a free bonus. The chart below outlines the differences:

 

GameDeposit Bonus ContributionFree Bonus Contribution
Slots100%25%
Video Poker20%5%
Roulette, Casino War, Mini-Baccarat10%2.5%
Blackjack2.5%0.625%

 

The only bonus that does not have a wagering requirement is the 15% cash back bonus. Cash back is only given however for real money losses, and not for bonus money losses. To qualify for cash back bonuses, players must not have any approved withdrawals within the last 7 days, and they must have at least one approved deposit in the last 7 days

Here are the games you can play at 21 Dukes Casino.

Originally designed for Duchesses and Dukes, slots have gone on to become the most popular gaming type in the world. No online casino can survive without offering slots so it’s hardly surprising that there are tonnes of them to play here.

Jackpots

Along with the slots, 21 Dukes Casino has jackpot games for players to chase massive wins from small bets. There aren’t many progressive jackpots here but there are a lot of fixed jackpots - some of which come close to matching the size of progressive jackpot prizes.

You must scroll through the library of games to find jackpot games as there is no separate category for them. They have a red mark on them so you’ll be able to spot them though.

Table Games

Games like blackjack and roulette are known and played all over the world. They are some of the most prestigious too, so it would be foolish to ignore them. 21 Dukes Casino has a variety of table games so you will have a great time playing your favorites, along with other variations to try if you fancy something new.

Here are some of the table games on offer:

  • Blackjack (American, Royale, Classic and more)
  • Roulette (American, European, French, Crystal and more)

Casual Games

21 Dukes Casino has a strong focus on bingo games. There are lots of different bingo rooms with different costs and prize pools. If you’re a fan of bingo, you’ll love what this online casino has to offer.

Live Dealer Games

Live dealer games bring the excitement and glamor of land-based casinos into your own home. With 21 Dukes Casino, real dealers are stationed at a brick-and-mortar casino and the action is shown to the players over video.

Live dealer games include live blackjack, live roulette and live baccarat.

Mobile capability 

The games at 21 Dukes Casino can be through the casino’s Instant Play feature. To use the Instant Play, all you need to do is login to your account and you’re ready to start playing your favorite games.

Unlike other casinos though, there is no option to download any dedicated software and play through the client. 

21 Dukes Casino can be played on mobile. Simply head to the casino through your smartphone or tablet’s browser, login and start playing. The mobile version of the casino works very well on all platforms and you can play most of, if not all of the popular titles, meaning you can take them anywhere and play at any time you want.

Promotions and bonuses

There are lots of bonuses and promotions at 21 Dukes Casinos.

Firstly, their welcome bonus is one of the largest you will find anywhere. It comes in two parts: the first as a no deposit bonus and the second as a deposit bonus.

Once you sign up, you will be awarded with 25 free spins without making a deposit. In terms of the deposit bonus, you can get a 200% match bonus up to $2,000 on your first deposit. There are also reload bonuses, such as a 100% match bonus on your second deposit up to $1,000.

In total, there are $6,750 worth of deposit bonuses to take advantage of, cementing the claim that it is one of the biggest around.

21 Dukes Casino also has daily match bonuses on offer for new and existing players. Old members of this online casino are rewarded with a cash bonus each time they make a deposit. The size of the bonus depends on the day of the deposit and how much they fund their online casino account.

For example, on a Monday, there are 5 offers, including:

  • 25% cash bonus on deposits up to $49
  • 50% cash bonus on deposits between $50 and $74,
  • 75% cash bonus on deposits between $75 and $99
  • 150% cash bonus on deposits between $100 and $199
  • 200% cash bonus on deposits of $200 or more.

On top of this, 21 Dukes Casino has tournaments where players earn points based on how much they wager on selected games. At the end of the tournament, the players with the most points win and collect a prize.

Here are some of the tournaments on offer:

  • Cash Craze - Deposit a minimum of $100 and qualify for this “$100,000 Giveaway” tournament where 1st place wins $50,000.
  • Crack the Casino Vault - Anyone can enter this tournament. Finishing 1st  place wins $7,500.
  • Dragon Race Party - There is no minimum deposit requirement to qualify for this tournament. All you need to do is play and collect the appropriate amount of points. A 1st place finish in this tournament wins $25,000.

All of these tournaments pay all the way down to around 20th place. In Cash Craze, finishing 30th can win you cash too. This means that there is a good chance of finishing in a paid position.

But every promotion at 21 Dukes Casino is subject to satisfying the wagering requirements. These differ when you play with a deposit bonus and free bonus money. 

For deposit bonuses, the playthrough requirements are:

  • 800% contributions for bingo
  • 100% contributions for slots
  • 20% contributions for video poker
  • 10% contributions for roulette, mini-baccarat, Casino War and Weed Whacker
  • 2.5% contributions for blackjack

For bonus money, the playthrough requirements are:

  • 200% contributions for bingo
  • 25% contributions for slots
  • 5% contributions for video poker
  • 2.5% contributions for roulette, mini-baccarat, Casino War and Weed Whacker
  • 0.625% contributions for blackjack

Loyalty rewards

All players at 21 Dukes Casino get 15% cashback on their weekly deposit total on the Monday of the succeeding week. For example, if you deposited $1,000 in one week, you will get $150 credited back to your account.

Cashback rewards are great because they can be withdrawn from your account straight away. This is different from other promotions and bonuses as they require you to meet some wagering requirements before you can cash them out.

21 Dukes Casino also has a 6-tier VIP program to reward loyal players. As you play the games, you will accumulate points. As you collect more and more points, you will progress to the next tier.

Silver is the first tier, requiring 1,000 points to become a member, while Master is the final tier, requiring 150,000 points to become a member.

As you progress through each tier, you will unlock better perks and features, such as bigger withdrawals, higher wagering limits, faster points earning and more.

Deposit methods 

21 Dukes Casino has plenty of options to fund your account. Here are the ways you can deposit:

  • Credit and debit card (Visa MasterCard, American Express, EcoPayz and Maestro)
  • Digital wallets (Skrill, Neteller and more)
  • Bank transfer
  • Paysafecard

Not all of these deposit methods are available in your location. However, 21 Dukes Casino ensures that at least one or more of these options will be available for use no matter where you are playing from.

Most deposits are processed instantly so you’ll be ready to play for real almost immediately. There is a minimum deposit limit of $10 so you don’t have to be a high roller to play here.

Withdrawal methods

Like with deposit methods. It’s important to have a range of withdrawal methods to get your winnings back to your bank account. While there are not as many withdrawal methods as deposit methods, you are not short of options.

Here are the ways you can withdraw funds at 21 Dukes Casino:

  • Digital wallets (Skrill and Neteller)
  • Bank transfer
  • Money transfer
  • EcoPays
  • Bitcoin

There is a minimum withdrawal limit of $50 and a maximum weekly limit of $4,000. Compared to many other online casinos, these are fairly generous.

Another important aspect of withdrawals is how long it takes until the funds are actually processed back to your account. 21 Dukes Casino takes around 72 hours to process a withdrawal, before a further waiting time until the funds are received.

If you choose to use a digital wallet, this will take up to another 48 hours, while it can take another 7 days if you decide to withdraw via a bank transfer.

Criticism / Controversies

There are few things that 21 Dukes Casino could improve on.

Firstly, there are no craps games so fans will have to find somewhere else to play.

If you decide to take advantage of the deposit bonuses, you can only bet a maximum of $5 per bet. 

If you wish to get in touch with customer support, there is no live chat feature or a customer telephone number so you will have to send an email.

But these are relatively small issues to deal with.

Bottom line

Overall, 21 Dukes Casino makes for a great online casino. There is a good selection of games to choose from and thanks to the variety of developers, they look great and run very well on all devices, including mobile. There are certainly worse online casinos out there so if you decide to play here, you will not be disappointed with your experience.
