NOTICE: 21 Dukes Casino has closed down in New Zealand.

21 Dukes Casino, a platform operated under the blacklisted Revenue Giants Affiliates program, offers an array of online gaming experiences. Its broad assortment of games sets it apart, catering to various player preferences.

However, it's not all rosy; the casino has faced criticism for alleged unethical business practices, including poor communication, delayed payments, and operating without an appropriate license. Hence, while it delivers impressively in gaming diversity, it drastically falls short in upholding industry standards of transparency and fairness.

This dichotomy of superior game offerings and questionable operational practices defines the unique position of this casino in the online gambling arena.

  • Pros
  • Wide variety of casino and live games
  • Multiple supported currencies.
  • Mobile-friendly platform.
  • Attractive free spins welcome bonus
  • Cons
  • Blacklisted under the Revenue Giants Affiliates program.
  • Ownership transparency issues.
  • Absence of a valid operational licence.
  • Delayed payment issues.
  • Limited responsible gambling resources.

First Glance at 21 Dukes Casino


While 21 Dukes Casino might first strike you as a no-frills, easy-to-navigate site, delving deeper reveals unsettling irregularities that may make even the most seasoned online gamblers raise an eyebrow. 21 Dukes Casino lacks thematic charm, without any particular character or theme to enchant its visitors.

The site’s navigation is straightforward, with a comprehensive menu to the right, providing quick access to different categories like casino baccarat, roulette, blackjack, poker, bonuses, bitcoin, crypto bonuses, support, and FAQs.

However, red flags, such as numerous spelling errors and an odd redirection to another casino called “King Billy”, are apparent. The footer is also unusually bare, offering only contact details and lacking the usual wealth of information about payment options, licenses, and other essential details.

25 free spins upon 1st deposit on Wolf Gold

21 Dukes Casino Welcome Bonus Offer


21 Dukes Casino greets new users with 25 free spins immediately upon the first deposit for the game Wolf Gold. This no-deposit bonus accepts all payment methods and requires no bonus code.

The casino also offers three deposit bonus codes of up to $10,000 and 110 free spins upon registration.

Interestingly, they offer an elevated bonus of 400% for transactions conducted using cryptocurrencies such as Bitcoin, Ethereum, Litecoin, Bitcoin Cash, or other altcoins. This rule applies to each first, second and third deposit made at the casino.

How to Sign Up & Activate the Welcome Bonus

We will now outline how to sign up and activate the deposit bonus at 21 Dukes Casino:

  1. Visit the 21 Dukes Casino homepage.
  2. Click on the ‘Join Now’ or ‘Sign Up’ button, usually found at the top right of the page.
  3. Fill out the registration form with your personal information, including your name, email address, and password.
  4. Confirm your account via the email address provided.
  5. Navigate to the deposit page and choose your preferred payment method.
  6. Make your first deposit to activate the welcome bonus.
  7. Once the deposit is successful, the welcome bonus should automatically reflect in your account.
  8. You are ready to start playing games, including ‘Wolf Gold’, where you can use your free spins.

Remember, no bonus code is required to activate the welcome bonus at 21 Dukes Casino. Registration and deposit are required to activate the bonus.

Wagering Requirements

We have checked the wagering requirements at the casino. Check the list below for a quick outline:

  1. The minimum deposit amount is $10.
  2. The bonus must be wagered within seven days.
  3. The bonus must be wagered 35 times.
  4. If you deposit $10, you must wager $10 x 35 = $350 to meet the wagering requirements.
  5. Not all casino games contribute equally to the wagering requirements.
  6. The bonus terms and conditions usually stipulate the maximum bet limit while wagering. Please refer to these for clarity.
  7. Free spin winnings are capped at NZ$200.

The bonus conditions at the casino seem standard compared to other online casinos. The wagering requirement of 35 times the bonus amount is pretty standard. However, players should be aware that not all games contribute equally towards meeting these requirements. Popular games like Wolf Gold, Might of Ra, Take the Kingdom, and Charms and Clovers are available for wagering the bonus.

Overall, this is a fair welcome offer with chances to win not only on the first and second deposit but the third deposit too.

Additional Bonus Offers & Promotions

This casino isn’t shy about offering a variety of free spins and bonuses to entice its players. The casino also provides a crypto bonus where crypto enthusiasts can use a 400% bonus on their first three deposits using cryptocurrencies.

Other promotions include the Saturday Race Championship. Here, the casino transforms your wagers into tournament points – for every $1 wagered, you receive 1 point. The more points you accumulate, the higher your chances of scooping the grand prizes. This blend of promotions ensures that players of all types have something to look forward to at 21 Dukes Casino.

Does 21 Dukes Casino have Special Promos or Reward Programs?


The casino has a six-tier VIP program for its loyal players. This includes Basic, Silver, Gold, Platinum, Titanium, and Master tiers. Players unlock benefits like exclusive tournaments, tailored promotions, and tons of free spins as they progress through these levels. Upper-tier players also enjoy the luxury of dedicated VIP hosts. However, detailed information about the program is somewhat lacking on their website.

How is the Game Selection at 21 Dukes Casino?


This casino provides a diverse game library across six categories. This includes Slots, Drops & Wins, Live Casino, Classic Slot, Roulette, Blackjack, and Video Poker options like Deuces Wild, Jacks or Better, and Joker Poker.

For those seeking an old-school experience, the casino features keno and scratch cards. However, for those seeking other games like bingo, lotto, or eSports, you may be disappointed as these are not currently offered.

What Game Providers Does 21 Dukes Casino Have?

A select group of game providers supports 21 Dukes Casino’s games selection. This includes Pragmatic Play, Rival Gaming, Vivo Gaming, Betsoft, and Octopus Gaming. All the games from these providers are renowned for 3D graphics and engaging bonus features, significantly enhancing the gaming experience.

The variety of game styles and themes with ten providers may be somewhat limited compared to other casinos boasting over 20 developers.

Nevertheless, the quality of these game providers shouldn’t be underestimated, and they offer an adequate gaming selection for those who appreciate their specific style.

Pokies Overview

With a robust selection of pokies, this casino provides players ample choice, from popular titles like Fire 88 and Irish Charms to immersive video slots such as Curse of the Werewolf Megaways and The Dog House. The software provider Pragmatic Play offerings promise engaging gameplay and unique themes. Crucially, a demo mode is available, allowing you to try these popular titles without staking real money.

Jackpot Pokies Overview

21 Dukes Casino has a suite of progressive jackpot games. Standout titles include A Night in Paris, Greedy Goblins, and Good Girl Bad Girl, each designed with top features to amplify your winning chances. Further jackpot games such as Faerie Spells, Dragon Kings, and Enchanted add to the exciting variety. Start playing the jackpots at 21 Dukes for the possibility of a colossal win!

Table Games Overview

For those who prefer the strategy of table games, this casino delivers a versatile array. Roulette lovers can spin the wheel in games like Crystal Roulette, while blackjack enthusiasts have options like Royale Blackjack. The poker offerings are impressive, too, including video poker such as All American Poker, Deuces Wild, Joker Poker Poker 3 Heads Up Hold’em, and Double Bonus Poker.

Live Dealer Games Overview

For players seeking the thrill of real-time gaming, 21 Dukes Casino’s live casino section doesn’t disappoint. With a lineup powered by leading software providers, it offers popular games such as Live Blackjack, Superb6, Live Baccarat, and Live English Roulette. If you’re a classic American Roulette or Blackjack VIP fan, the immersive live experience is available at your fingertips.

Banking & Payment Options at 21 Dukes Casino


The casino has payment options catering to international and local players. It supports popular methods such as VISA and MasterCard credit and debit cards, ecoPayz, Bank Transfers, and cryptocurrencies. This flexibility is pretty standard compared to other online casino sites.

However, while the casino ensures fast, safe, and secure transactions, it doesn’t currently support Pay’n’Play payment method options like Trustly, Zimpler, or Brite.

Deposits, Withdrawals & Payout Speed

The casino provides a variety of deposit methods, including VISA, Maestro, Bank Wire Transfer, Bitcoin, Paysafecard, Skrill, Neteller, and Payz. The minimum deposit limit is set at an affordable $10. Interestingly, other review sites mention additional banking methods, suggesting that the casino might use geo-targeting to tailor its displayed payment method options. While the casino warns of possible fees on credit card transactions, Bitcoin payments are fee-free.

Cashing out your winnings, unfortunately, is a less pleasant affair. Withdrawal options are limited to Bank Transfers and Visa Cards, each carrying substantial minimum withdrawal limits of $500, $300, and $100, respectively.

These methods also come with fees ranging from $10 to $23. Even more disappointing are the maximum withdrawal limits, beginning at a mere $500 per week, although Titanium Level Members can increase this limit to $10,000 per week. Withdrawal times vary, too, with Bitcoin boasting a 2-hour payout, while bank transfers take 5-7 days.

The casino supports currencies, including Euro, Bitcoin, US dollars, Canadian and Australian dollars. Unfortunately, NZD is not among them. It’s worth noting that the site isn’t particularly transparent about this information, making it somewhat of a chore to find. Indeed, withdrawal options, limits, and fees may vary depending on the currency used, adding another layer to the puzzle

KYC Process & Documents


This online casino maintains a standard KYC process to ensure user security. Verification documents may be required at any stage, including sign-up or withdrawals.

The requested documents include vouchers of credit/debit cards used in the past six months and proof of ownership of the payment method, which may necessitate a recent bank statement or e-wallet screenshot. Submitting these documents before review time is essential for a smooth withdrawal process.

Customer Support at 21 Dukes Casino


This casino advertises round-the-clock customer service. While online casino support is offered in several languages, the live chat function often has long wait times, taking around 25 minutes to connect with a representative. Similarly, email responses may take up to two days. Although easy to locate, the FAQ section provides vague answers and lacks in-depth detail, limiting its usefulness.

21 Dukes Mobile Compatibility


The casino has robust mobile compatibility with its platform for seamless operation across various mobile devices. Users can enjoy over 500 online casino games on their desktop and mobile devices, such as slots, poker, roulette, and blackjack, with a single login.

The games are accessible through a mobile-optimized browser or a dedicated app, providing flexibility to players. The mobile experience is competitive in the market, with only the live dealer feature notably absent for mobile users. No additional downloads or specific software is needed to enjoy 21 Dukes Casino on the go, ensuring a user-friendly gaming experience.

Player Safety & Responsible Gambling


21 Dukes Casino demonstrates a commitment to responsible gaming. The online casino provides several options for self-exclusion, allowing players to set personal limits on deposits, maximum bets, and playing hours. These controls can be adjusted within the user interface, providing players a straightforward way to manage their gambling habits.

The casino’s website also includes comprehensive information about responsible gaming, outlining measures to prevent problem gambling. In cases of problem gambling, the casino provides support and necessary guidance to players, reinforcing its commitment to player safety.

Licences & Security

  • Company: Possibly Engage Entertainment Group Inc. or Winward Hall Ltd.
  • Address: N/A
  • Licence: Costa Rica Gambling Authority (alleged)
  • Licence Number: N/A

This online casino is blacklisted due to shady business practices associated with the Revenue Giants Affiliates program. These practices range from a lack of cooperation and communication with affiliates to delayed or declined payments. Disturbingly, they operate without a valid license from a recognized regulatory authority.

The casino’s opaque ownership structure, potentially tied to Engage Entertainment Group Inc. or Winward Hall Ltd., raises further questions about their credibility. Furthermore, they lack partnerships with trustworthy independent organizations like eCOGRA or iTech Labs and don’t provide direct links to responsible gambling support sites such as Gamblers Anonymous.

21 Dukes Online Casino Verdict


21 Dukes Casino presents a complex picture. On the one hand, all these games cater to experienced players and newcomers, providing a wide range of games, free spins, and appealing promotions that can entice any player. However, it’s impossible to ignore the significant concerns that arise from their affiliation with the blacklisted Revenue Giants Affiliates program.

They have been implicated in unethical business practices such as lack of communication, non-cooperative behaviour, delayed or declined payments, and unprofessional conduct. Furthermore, the validity of their licencing is in question, with no evidence of a legitimate, officially recognized license available. This lack of transparency and integrity seriously undermines players’ trust in the casino.

Notable concerns overshadow the casino’s engaging game variety. Players are advised to approach this platform with caution. My experience was unsatisfactory; the website felt unrefined, suspicious, and the sign-up process was challenging. Despite its robust promotional offers and diverse game selection, better alternatives exist.

My verdict is a disappointing D-.
