21Dukes Casino has been operating for over 10 years now and in that time they have managed to create and shape their casino to welcome players from all over the world. The extra features that they have integrated into the 21Dukes experience has also been impressive with the startings of a live casino, cryptocurrency banking, and some high-end promotions that obviously keep their members coming back for more every week. You shouldn’t be expecting anything too flashy in terms of the website, though. The main focus here is on the gaming experience and we will be looking more into that and more over the following review.

21Dukes review

What to expect at 21Dukes:
  • Lucrative promotional calendar
  • Mixed game selection in the lobby 
  • Experienced casino with many years in the business
  • Cryptocurrency banking options
  • Jackpot and Megaways games

Game Selection

Casino, Live Casino & Jackpots

The lobby at 21Dukes is as simple as it comes with a grid layout and basic sorting abilities. You can sort by new games, software providers, top games, as well as listing all the game titles from A to Z. The side menu is just as useful as you can quickly click through to slots, table games, video poker, live casino, and classic slots. And, of course, the ever present search bar is a welcome feature that lets you quickly locate any game that is on your mind.

Slots and table games

The number of games found at 21Dukes is not the biggest that you will come across on your online casino journey and at well below the 1,000 mark, you do feel a little bit limited as you scroll through the lobby. This is, however, all down to the lack of software providers on board and as you will soon find out, there is a lot more needed in this section if they want to keep the casino alive.

A total of four software developers can be found in partnership with the casino and the two big names here are Pragmatic Play and Betsoft, with the other two being Vivo Gaming and Octopus Gaming. The first two are, of course, very well known on the iGaming scene and so there is a big selection of high quality games on show, even if the total number is a little low. The themes are wide-ranging and there is a good mix of old and new titles to keep all types of players engaged and entertained.

The table games section is well stocked with a good selection of games from pontoon to baccarat to keno, as well as the classics of roulette and blackjack. There is a good mix of games and the dedicated video poker page is something that poker fans will appreciate with over 30 different variants on show. You will find plenty of casino entertainment here but whether it is a casino that you will be playing at for months on end remains to be seen.

Jackpots at 21Dukes

It might take you some time to find the jackpot games at 21Dukes so let us give you a little head start if you do decide to play there. Head to the lobby and sort through the software provider option and then click through to the Betsoft collection. Here you will find all the jackpot games on offer and they will be easy to find as they are marked with a red ‘Jackpot’ label.

The total number of jackpots is again not the most inspiring and there is no option to play the big progressive jackpots that we all know and love. However, there are jackpots and some offer reasonable amounts that are worth playing for. Another little tip from us would be to give the Megaways games a spin, these are not technically jackpot titles, but they do provide plenty of big payouts.

Live Casino games

The recurring theme of limited games continues in the live casino section and we wouldn’t be surprised if you become confused as us when you click through from the Live Casino menu tab. A total of two games can be found here and you might wonder if it was really worth their time in signing the deal with Vivo Gaming. 

Blackjack and roulette are both available and so at least the two top favorite games are playable, and we can only hope that the casino decides to add to this miniscule collection. Live casino is only ever getting more popular and so the team at 21Dukes really do need to get up to speed before they miss out on all the action.

The chance to play one of the two games available here at least gives players a taste of what live casino is all about, and so for that perhaps some people will find some value. But for now, we can’t help but feel a little deflated by that disappointing two-game collection.

21 Dukes Casino Games

21Dukes welcome offer

The casino picks itself up after that uninspiring lobby with a cracking welcome offer that throws in bonus money and spins at every turn. Let us start at the start though and first up you will be given 25 spins for simply entering a few pieces of information and creating your 21Dukes account. If you are happy with that and you want to continue then your next three deposits will reward you with even more bonuses. Here is how the offer stacks up in simple terms:

Deposit One - 200% Bonus + 30 free spins

Deposit Two - 250% Bonus + 50 free spins

Deposit Three - 300% + 30 free spins

The 21Dukes bonuses are huge with up to €3,000 available on the third deposit and the smallest maximum is still €2,000, so there is a lot to claim here. However, don’t go all in just yet because as with most casino bonus offers, the real value is actually found in the terms and conditions. Some details that are made clear include the €200 cash winnings available from the no deposit free spins, but read on for the all-important wagering requirements.

Bonus terms and wagering requirement

First up, the minimum deposit of €10 is what most players are comfortable with and, of course, you are free to deposit more to take advantage of those high bonus amounts available. However, the next bonus rule dictates the true bonus value and here we have a 35x deposit + bonus wagering requirement, which, unfortunately, is not something that we would call player-friendly. Other standout rules include the bonus money expiring in seven days and the fact that you also need to select the correct bonus offer within the ‘Claim a Bonus’ section of the site.

Promotions and bonuses

The 21Dukes promotion calendar is one of the highlights of the casino and the two standout offers are called Races and Road to Rome. Races are all about slot game races where you play to win cash prizes with minimum bets and time limits included. The Road to Rome offers up treasure chests upon depositing specific amounts and you can claim free chips, spins, cash rewards, and Amazon vouchers as well.

On the main promotions page, you can find even more enticing offers with tournaments, cashback deals, crypto-specific deals, and plenty of deposit match bonuses to enjoy. While there might not be thousands of games here at the 21Dukes casino, there are lots of chances to boost your bankroll every day.

The 21Dukes casino design has not been overloaded with graphics and animations and it very much sticks to a traditional layout. Whereas some modern casinos treat players to animated backgrounds with interactive pages, this casino sticks to a plain black background and a simple yet intuitive main menu down the left-hand side. It works though and you can easily and quickly find your way around the casino pages with no extra clutter getting in your way. The big promotions are right there in the menu and the main games types are also there as well. 

Modern features might be missing like the detailed filter options but the simple sorting function works well enough and the search bar becomes useful once you know what games to look for. All in all, if you are not one for fancy artwork and unique branding then 21Dukes casino offers you everything you need. Of course, a few more games would be great but as for the usability and navigation, then you can’t really fault it.

Mobile Casino

The 21Dukes mobile casino experience is perhaps what most players will be engaging with as it really is a straightforward design, which is what you want when playing on small handheld devices. The simple design lends itself well to the mobile experience and so that standard lobby grid and main menu provide an easy way to navigate the site.

The games themselves are mostly optimised by the software developers and so you can rely on the likes of Betsoft and Pragmatic Play to provide you with the right mobile features. Things like touchscreen controls and easy-to-read rules come as standard and so spinning the reels or playing a few hands of blackjack is very much a natural experience. 

Of course, all the main features from the desktop are transferred onto the mobile version and so those promotions and bankroll boosting offers are all available to you. The 21Dukes mobile site doesn’t include all the modern features but it certainly does enough to let you play on the go whenever the feeling strikes you.

21Dukes Help and Support

Email is the chosen contact channel at the casino and you can find the email address from the Contact link in the footer, however, there is a live chat feature available once you open an account and log in. Alternatively, a well researched FAQ section can be found which does answer most of your common questions and casino problems.

These are the main categories in the 21Dukes FAQ:

  •       Most Popular
  •       Account
  •       Verification process
  •       Promotions & Bonuses
  •       Deposits
  •       Withdrawals
  •       Wagering requirements

Deposits and Withdrawals

It might take you some clicking to find the banking section at this casino which is starting to be another recurring theme, but once you find the page then you will discover that you have quite a lot of payment options open to you. E-wallets like Skrill, Neteller, and ecoPayz are popular and the Mastercard and Visa options always put the minds of players at ease. The crypto options of Bitcoin and Litecoin are also open for those looking to use that specific type of payment.

Minimum deposits of €10 are available and this is standard for most casinos and allows casual players to sign up and test the site before spending too much of their money. The maximum deposit amounts are not currently being displayed and so you might need to contact the support team to clarify any larger amounts. 

The maximum withdrawals all depend on your own VIP level and most levels give you a €4,000 limit with just the top two levels offering custom limits. The 72-hour processing time to approve the withdrawals is not something that their members think too highly of though, so don’t expect to get your winnings too quickly when requesting a withdrawal.. 

Verifying your 21Dukes account

The casino needs to carry out various checks and these can be carried out up to two times per year. Several checks may be asked of you and these include proving your identity, proving your address, and proving the ownership of your choice of payment method.

A full list of documents is not displayed but some examples are included along with various checklists to ensure that your documents are approved first time. This is helpful in keeping things running smoothly and to stop any future delays to your withdrawal transactions further down the line. Once your account is approved, the status will change in the Account Verification section.

Security and Licensing

The lack of business clarity is a worry for 21Dukes casino and there is a lot of missing information where we would usually look for it. The bottom of the homepage does not include the business name, the registration address, nor the license details. With a bit more poking around we did find the business to be operating under the name Blacknote Entertainment Group Limited Casinos. The website does not display any information regarding an official gambling license, which is worrying.

The lack of detail does not help when it comes to holding a level of trust with the players and so the casino is not helping themselves when it comes to the security factor. On the plus side, there are several approval badges on the homepage and an SSL certificate from Cloudflare. These features do help to secure some security for players, but if they want to gain complete trust from the players then they need to start including their official details clearly on the site.

Conclusion of 21Dukes review

21Dukes casino is an incomplete gaming site in terms of present-day standards, but yet it still holds some entertainment value due to its small but quality casino lobby, which is also backed up by the long list of promotions and bonuses. You can boost your bankroll every week with various ongoing offers and tournaments. So, although the lobby might be lacking volume in total game numbers, if you do find games here that you like then a huge bankroll to play them with is very much possible. Elsewhere, the live casino is almost empty with just two games and along with the lack of software providers, it really hits home that this site is short in supply when compared to other online casino lobbies. 

Couple this with the lack of official detail on the license and operating company and you have a casino that loses that all-important trustworthy first impression. You can find the information with a little digging about and we did find that all the necessary security features were in place, in a technological sense anyway. So, if you like the look of the promotions on offer on the site and if you can find some games that you might enjoy, then the 21Dukes casino may hold some decent gaming entertainment for you. It is worth a closer look and so to begin with you can always claim the free ‘no deposit’ spins first before you decide to make a deposit or not.

21Dukes has good bonuses when you sign-up and you can pretty much choose whatever suits you best. I clicked through their pages and was pretty impressed. Good pokies selection (my personal favourite) and live was well stocked. Well curated catalogue overall.
Bonus comes with caveats (like always) so make sure to check once you choose. Chat is there in case you need it.

The promotion section is pretty interesting and you are basically guarenteed to get a big bonus when you sign up. I was able to make my first dep with bitcoin which I was happy with.
Some of the bonuses come with staggering requirements. The site itself has a good setup but I was turned off by the hidden bonus. Still a good game selection, just be careful when selecting the promos.
