So, you’ve heard about 21 Dukes Casino, and you’re wondering if it’s a casino worth playing at?

Well, you’ve landed in the right place. That’s exactly the question I’m going to be answering in this 21 Dukes casino review.

If you’re a first-time reader at, welcome, and don’t be surprised by how things are done here. Unlike many other casino review sites, you’ll find the truth here, and if a casino has some points of concern, I’ll let you know what they are.

By the end of this review, you’ll know all you need to know about 21 Dukes casino to make a fully informed decision about whether or not to play here.

Let’s begin!

About 21 Dukes Casino

21 Dukes has been online since 2008 and is owned and operated by Engage Entertainment Group Inc.

Since then, this site has built up a large player base of players from all over the world. It’s known for being one of the first casinos to accept Bitcoin and is still a Bitcoin-friendly casino today.

21 Dukes casino has a valid gaming license from the jurisdiction of Curacao. That’s a reputable license and combined with the encrypted connection, it means you can trust this casino.

Those are the somewhat dry details covered. Now, let’s take a look at who can play before turning our attention to other important elements.

Who Can Play at 21 Dukes Casino?

Players from the following countries are restricted at 21 Dukes:

  • United States
  • United Kingdom
  • Czech Republic
  • Denmark
  • Germany
  • Ireland
  • Israel
  • Netherlands

There are some other restricted territories. See the terms and conditions for a full overview of who can and can’t play here.

If you’re from one of the above countries, then check out some of the other reviews on this site. There are plenty of other casinos which do accept you.

Software Suppliers

After checking the gaming licenses and the security of the connection, I always look at the software suppliers as the next most important thing. This tells me everything I need to know about the games and what to expect quality-wise.

I’m happy to report that 21 Dukes casino is working with some of the best in the business. I did have to look up one of them (Octopus Games) as I didn’t know too much about them, but it turns out they’re fine and are specialists in mobile gaming.

You can play games from:

  • Microgaming
  • Betsoft
  • Pragmatic Play
  • Octopus Gaming
  • Rival Gaming

What does this mean? It means you’ll be playing the best games available online if you play at 21 Dukes casino.

The Good Stuff

There’s a Large Range of High-Quality Games

Good Stuff
The games are the core of any online casino, regardless of what else it offers. A handful of low-quality games is useful to nobody, and I’m glad to report that’s certainly not the case here.

I found games from Betsoft, Microgaming, and Pragmatic Play, which are some of the top games providers in the industry. Every type of games is offered, from video poker to table games to slots to live dealer games.

Whatever you’re into, you’ll find it here. You can trust these software firms, and they provide super high-quality games.

Bitcoin Is Supported

I became a Bitcoin convert a couple of years back after using it to play at another online casino. The ease with which I was able to get my money out, combined with the speed at which I received it, convinced me to use it for most online transactions of a given size going forward.

21 Dukes casino is a Bitcoin-friendly casino. I’m not a big fan of its Bitcoin bonus (see below), but I still think this is the best way to make deposits and withdrawals. Best of all, it’s fee-free.

Slots Tournaments Occur Weekly

If you are a competitive person and love slots, the slots tournaments at 21 Dukes casino will likely become something of a regular fixture for you.

I like that the winnings are paid as cash with no wagering requirements. I also like that there are Sunday tournaments as well as regular ones during the weekdays.

Of all the offers and bonuses available, I think the slots tournaments represent the best deal at this casino.

The Bad Stuff

No Sports Betting

Bad Stuff
Ideally, I like to be able to bet on whichever football matches and fights are happening in any given week. Unfortunately, sports betting isn’t offered at 21 Dukes.

That’s not a deal-breaker, though. I could always play here and bet somewhere else on my mobile device.

Higher-Than-Average Wagering Requirements

I understand that a casino has to offset its risk when offering free cash to new players. However, there comes a point when it gets a little over the top, and unfortunately, 21 Dukes casino crosses that line.

Some of the bonuses are subject to 99x wagering requirements. Come on, 21 Dukes! You can do better than this.

Game Selection


Every player is different. Some like slots, some prefer to grind out a profit playing video poker, and some prefer the all-or-nothing games like keno or lotto. The best online casinos know how to cater to every type of player.

21 Dukes casino does provide a comprehensive range of casino games across the spectrum. No matter what type of game you like, you’ll find something to suit here.

Let’s look at each game category one by one and see what exactly is on offer.


There are a handful of digital poker games available at 21 Dukes. These aren’t the live Texas Hold’em tournaments you might find at some other sites, but rather games you’ll play against the house.

The following games are offered:

  • Three Heads Up Hold’em
  • Oasis Poker
  • Caribbean Stud Poker
  • Caribbean Hold’em Poker
  • Triple Edge Poker
  • Three Card Rummy Poker

Feel free to check these games out in demo mode before you play poker for real money. Once you decide to bet, you can play for anything between $1 and $200 per hand, depending on the variant.

Video Poker

I learned how to play video poker in a bookmaker’s shop when I was a teenager, and I’ve been playing ever since. This lifelong fascination stems from the fact that I won the first time I played and have won regularly since. If you take the time to learn video poker strategy, it’s possible for you to win regularly, too.

I’m impressed with the number of games available at 21 Dukes. It’s likely that you will be, too. Check out the following games:

  • All American
  • Aces and Faces
  • Deuces and Joker
  • Deuces Wild
  • Double Bonus Poker
  • Deuces and Joker
  • Double Jackpot Poker
  • Double Joker
  • Jacks or Better
  • Joker Poker
  • Poker Pursuit
  • Split Way Royal
  • Tens or Better

Games are provided by both Pragmatic Play and Microgaming, so the quality is world-class. The games load quickly and run perfectly on any device.

Bets start from $1 per hand to as much as $25 per hand. There are 1-hand, 5-hand, 10-hand, and 50-hand versions available if you want to up the ante.

Table Games

Digital table and card games are slowly dying out to live dealer versions, but there are still some casinos which offer lots of them. Thankfully, 21 Dukes is one of them.

The following games are available:

  • Baccarat
  • Baccarat Gold
  • Classic Blackjack
  • American Blackjack
  • European Blackjack
  • Spanish Blackjack
  • Atlantic City Blackjack
  • Vegas Strip Blackjack
  • Double Exposure Blackjack
  • Super 7 Blackjack
  • Pontoon
  • American Roulette
  • European Roulette
  • Crystal Roulette
  • Titanium Roulette
  • Black Diamond Blackjack
  • Multi-Wheel Roulette
  • Common Draw Roulette
  • Vegas Craps

The table and card games are provided by a few software providers, including Microgaming, Rival, Octopus Gaming, and Betsoft. While I had to do a little research on Octopus Gaming, they’re legit, and you don’t have anything to worry about from either trust or quality standpoints.

You can enjoy these games for free in “demo mode” before you commit to playing for real cash. If you do decide to play for real money, you can bet anything from $1 to $500 per round/hand/roll.


80% of all casino players say that video slots are the main game they play. If you’re one of them, you’ll be pleased with the range of Betsoft, Microgaming, and other slots you can play at 21 Dukes casino.

I recommend checking out the following games:

  • Mr. Vegas
  • FaFa Twins
  • The Slotfather II
  • Heist
  • Tycoons
  • After Night Falls
  • Sugar Pop II
  • The Angler
  • Rooks’ Revenge
  • Fire and Steel
  • Fruit Zen
  • Mama Mia
  • Break Da Bank Again
  • Game of Thrones
  • Playboy Gold
  • Jurassic Park
  • Jungle Jim
  • Immortal Romance
  • Lost Vegas
  • Cool Buck
  • Hellboy
  • Fortune Girl
  • Pistols and Roses
  • Girls with Guns

As with the other games at this site, you’ll be able to try before you buy. I like this feature a lot and wish more casinos on the web would have the confidence in its games that offering them for free communicates. It’s a great way to find new slots with cool features without wasting money playing duds.

All of the games are high-quality and load quickly. Well done, 21 Dukes Casino!

Live Casino

While I personally still prefer digital games, I can totally see why so many players prefer live dealer versions. The big three casino games are offered with live dealers at 21 Dukes. These include:

  • Baccarat
  • Blackjack
  • Roulette
  • Super 6

Unlike the other games on this site, you won’t be able to play these for free. You’ll have to pay to play from the first hand of cards or spin of the roulette wheel.

The games are all super high-quality and are as good as any I have encountered elsewhere online. If you enjoy live games, you’ll be all good here.

Other Games

If you want to take a break from the “regular” casino games and play something which requires no thought or strategy whatsoever, then you can enjoy the following:

  • Scratch Cards
  • Virtual Sport
  • Bingo
  • Keno



For a casino to appeal to me as a potential long-term player, I need to see two things – a healthy welcome bonus with fair terms, and a few reasons to play during the week or at least on weekends.

21 Dukes casino does offer a healthy welcome bonus, and there are regular slots tournaments if you like to spin the reels.

However, not every bonus at every online casino is worth taking. In this section, I’ll take a closer look at some of the bonuses new players can look forward to, as well as the terms and conditions surrounding them.

So, is 21 Dukes playing fair? That’s what I’ll show you in this section.

Welcome Bonus

As a new player at 21 Dukes casino, you’ll be able to claim a five-stage welcome package. This means you’ll be rewarded for five separate deposits. The offer is structured as follows:

  • First, you can claim a 200% deposit match + 25 free spins on slots
  • Second, you can claim a 100% deposit match
  • Next, you can claim another 100% deposit match
  • Then, you can claim yet another 100% deposit match
  • Finally, you can claim a 175% deposit match if you reload a fifth time

There’s no information on the maximum bonus available, but the live chat agent informed me there’s no upper limit. The minimum deposit at each stage is $10.

The wagering requirements are 75x, which are way higher than I’d like them to be. There’s also a maximum withdrawal limit of $100 on anything you win.

Bitcoin Bonus

If you’re a Bitcoin convert like me, you can claim 400% deposit bonuses on your first three Bitcoin deposits.

However, there are no clear bonus terms, and the live chat operator dodged my question when I asked. All I could gather from the terms and conditions is that all bonuses other than the welcome bonus are subject to 99x wagering requirements.

Honestly, I wouldn’t take this bonus. If it’s legitimate, and I wasn’t about to deposit my precious Bitcoin to find out, I wouldn’t take any deal with 99x wagering requirements attached.

My “skeptic radar” really goes off when live chat agents won’t answer questions directly or when they refer me to terms and conditions which don’t have the information I’m looking for.

Sunday Storm Slots Tournament

There’s no doubt that Sundays can be a little slow and depressing. Heck, Johnny Cash even wrote a song about that!

21 Dukes casino aims to spice things up before the new work week begins by offering you the chance to participate in a slots tournament with a top prize of $2,500. Even if you come in 25th, which is the lowest winning position, you will win $50.


You’ll need to make a minimum deposit of $50, and you’ll earn 1 point for every $1 wagered. If you play selected slots, you can get 2 points for every $1 wagered.

The tournaments take place between 06:00 and 12:00 UTC every week.

I’d definitely consider playing in this if you enjoy slots. All prizes are credited in cash, so they don’t have to be wagered. This is a much better deal than the bonuses listed above.

There are some other regular slots tournaments. These seem to come and go, rather than being something constant. Make sure to keep an eye on the promos page to see which ones are live and on which days of the week. They’ll all have their own terms and conditions, though, so don’t assume the buy-ins or terms are the same.

Bonuses Summary

Personally, 21 Dukes casino’swagering terms are higher than I would like on the welcome offers. I would potentially take the welcome cash bonuses because free-play is free-play at the end of the day. I wouldn’t take the Bitcoin bonus, though, because of the lack of clarity surrounding the terms and the poor effort on behalf of the customer service to clear up my questions about it.

The slots tournaments do seem to be genuine good deals, though. The prizes are paid as cash and can be withdrawn right away. This is more like it!


Every casino has a weak spot, and the number of ways to make deposits and withdrawals is the weak spot at 21 Duke. There are only three ways to make either deposits or withdrawals, and no web wallets are supported.

The good news is that there are no fees from the casino side. Your card issuer may charge a fee, though, so be sure to check that before making a deposit/withdrawal using your credit or debit card.

Bitcoin is supported, which I really like to see. This is my preferred payment method at casinos which support it.

As far as wait times go, you can expect to get payouts via Bitcoin the same day. For withdrawals by credit and debit card, you may have to wait 3-5 business days before the money reaches you.

Deposit Methods

  • Credit Cards
  • Debit Cards
  • Bitcoin

Withdrawal Methods

  • Credit Cards
  • Debit Cards
  • Bitcoin

VIP Program


As with many other casino VIP programs, the 21 Dukes casino program has several levels. You climb these levels by accumulating loyalty points. The more you play, the higher you climb, and the greater the rewards become.

The program is structured like this:

Silver – 1,000 Points Required

  • You’ll get a 50-point birthday bonus
  • You’ll also get a 50-point anniversary bonus

Gold – 5,000 Points Required

  • You’ll get a 100-point birthday bonus
  • You’ll also get a 100-point anniversary bonus

Platinum – 20,000 Points Required

  • You’ll get a 200-point birthday bonus
  • You’ll get a 200-point anniversary bonus
  • You’ll get access to exclusive bonuses
  • You’ll also get access to VIP-level tournaments

Titanium – 50,000 Points Required

  • You’ll get a 500-point birthday bonus
  • You’ll also get a 500-point anniversary bonus
  • You’ll get higher betting limits on games
  • You’ll enjoy access to exclusive VIP tournaments
  • You’ll be offered enhanced VIP bonuses

Master – 150,000 Points Required

  • You’ll get a birthday surprise
  • You’ll also get an anniversary surprise
  • You’ll enjoy higher bet limits on games
  • You’ll have access to VIP promotions
  • You’ll get invitations to exclusive events
  • You’ll also have your own dedicated VIP manager

This is a competitive VIP program. You’ll need to be betting serious cash to reach the upper levels, as 1 point is generally given for a $1 bet, but hey, that’s what being a VIP is all about.

Customer Service

Getting in touch with the casino is easy. There are three ways to do so:

Email – If you have a matter for which you don’t need urgent answers, email will suffice. You can drop a line to [email protected] – expect to wait up to 12 hours for a reply if the casino is busy.

Live Chat – You can contact the live chat support at any time, 24/7. This is good, but I feel slightly conflicted about the level of service I received.

On the one hand, the replies were fast and professional, but on the other, the agent simply did not answer one of my questions regarding the Bitcoin bonus. Instead, she told me to look in the terms and conditions, which I had already done.

While she did answer some of my other questions, I felt that perhaps this question was deliberately not being answered. That’s not a great sign.

FAQ – There’s a fairly comprehensive FAQ section offering answers to the most common account, financial, and bonus questions.

I found some useful answers here, rather than just generic answers. This is well done, and 21 Dukes deserves some credit for it.

I would like to see freephone telephone support added for players everywhere. Apart from that, the customer service at 21 Dukes is fine. It could be better, but I’ve also experienced a lot worse.

Would I Play at 21 Dukes Casino?

Yes, I would play at 21 Dukes, but I wouldn’t take all of the bonuses offered.

The range of games is fantastic, the customer service is fine, the site is user-friendly, and the slots tournaments are well worth participating in. No matter what type of player you are, you’ll likely have a great time here.

The best way to find out, of course, is to check it out for yourself!
