21Dukes Casino Review

Over the last few years, we’ve seen plenty of “crypto casinos” open their doors to the public – online gambling dens where you can only deposit using Bitcoin, Dogecoin and other cryptocurrencies (rather than flat currencies, like the Australian dollar). There are many reasons for their popularity, chief among them being that crypto transactions are subject to far less scrutiny from financial authorities.

This has certain advantages, namely that deposits and withdrawals are easier… But the downside is that you’re also far more likely to be scammed, with no recourse available to get your money back. That’s why you’ll have to be extra careful when evaluating casinos like 21Dukes – but luckily, we’ve done all the heavy lifting for you! In this comprehensive review, we’re going to examine its games and bonuses, as well as safety and reputability.

So, does 21Dukes have what it takes to duke it out with the best, or is it merely a peasant among royalty?

21Dukes Casino Review Australia


No Deposit Bonus – 25 Free Spins

A no deposit bonus is one that the casino will give you directly, without demanding anything in return – not even a first deposit. This is done as a sign of trust, or a gesture of good will… Which is why it’s so rare in the casino industry. Of course, that’s all the more reason why it’s a pleasant surprise to discover one, and 21Dukes Casino does not disappoint!

Once you sign up and confirm your account, you’ll be entitled to 25 free spins, on the house. Upon receiving them, you’ll have 7 days to have fun with them before they go poof, and during that time you’ll have to wager them x20 times if you want to withdraw them. It’s important to note that the maximum withdrawal amount is AU$100 (so no matter how much you win from the spins, you can only get AU$100 out of them), but we doubt most players would complain, given the fact that it’s basically free money.

Welcome Bonus – Up to AU$7,500 + 110 FS

No deposit bonuses are one thing, but ultimately, the casino wants you to deposit – how else are you going to play the games? That’s why it’s essential for the first deposit bonus to be satisfactory, and luckily, 21Dukes Casino doesn’t disappoint here either – in fact, you’ll be getting a bonus for each of your first 3 deposits.

The first 3 times you place a deposit, you won’t only get a very high match percentage, but also some free spins! Here’s what each of those first deposits will net you, exactly:

Deposit Match percentage Maximum bonus Free spins
First 200% AU$2,000 30
Second 250% AU$2,500 50
Third 300% AU$3,000 30

Unfortunately, there’s bad news: despite how generous the bonus seems, the requirements to withdraw it are a bit on the steep side, especially compared to the no deposit bonus. You’ll still have a limit of 7 days in which to wager it, but this time, you’ll have to do it x35 times. On top of that, you’ll be limited to withdrawing only AU$500 from the match bonus and up to AU$200 from free spins.

This will certainly be disappointing to hear, especially in light of the huge numbers the casino lists publicly. No one wants to get a bonus of AU$3,000 and then only withdraw a measly AU$500 from it!

Weekly Reload Bonuses

Ultimately, even the greatest welcome bonus will be all used up – and when that happens, it’s up to the reload bonuses to pick up the slack and give additional rewards to the loyal players. At 21Dukes Casino, those come in the face of regular weekly deposits that you can get every day.

How does it work? Well, depending on the day of the week on which you deposit, as well as the deposit amount, you’ll be receiving a different bonus amount. The lower deposits tend to be the same, but if you’re a high roller who likes to deposit hundreds of dollars at once, it’s best to keep an eye on the days of the week when that’ll be rewarded with the biggest match bonus.

Wondering which days those are? No worries – we’ve compiled a handy guide to show you how much you’ll get for depositing every day:

21Dukes Casino Review Australia


There’s no doubt about it – 21Dukes Casino provides its players (new and existing ones) with some of the biggest and best bonuses around! But ultimately, even a “play any casino game free” card will be completely worthless if there aren’t any games to use it on, right? Which is why we’re a bit saddened to say that the casino’s games are a bit of a mixed bag.

Don’t get us wrong – the pokies section is quite impressive, with plenty of fantastic developers providing their games. But, if you’re not a big fan of pokies, you’ll find yourself in a bit of a bind, as the casino doesn’t offer much of value beyond that: no live games, very few table games, no bingo or sports betting or anything like that. This will certainly be a deal breaker for many people who prefer cards and dice to reels and spins.

At first glance, you might have noticed that there’s only a few hundred games available at 21Dukes Casino – a far cry from other casinos, which sport thousands upon thousands of games. Well, you don’t need to worry, because the number of games never feels small while you’re actually in the casino – especially given their fantastic quality!

A great number of top-notch developers, such as FunGaming, Betsoft, IGTech and Pragmatic Play have all provided their games to the casino, letting you enjoy popular titles like “Wolf Treasure, “Diablo 13”, Wild Diamond”, “New Tales of Egypt”, “Gladiator” and many more! It’s practically guaranteed that you’ll find at least a few favorites (old or new) while browsing through the games list.

Classic pokies like “Lucky Seven” and “Red Chili Hunter” are also there – albeit not in huge numbers. The big draw for many will undoubtedly come from the selection of jackpot pokies. Slots like “Faerie Spells”, “A Night in Paris”, “Wild Sevens” and “Charms and Clovers” all have rather big progressive jackpots attached to them, which should make them rather appealing to many pokie enthusiasts.

Live casino

If you aren’t a big fan of spinning reels and matching symbols, then you were probably looking to be dealt some cards or bet on black at the casino’s live section. Unfortunately, as of the time of this writing, 21Dukes Casino does not provide its players with any live casino games, with the section having been removed in a recent redesign.

If this was a big draw for you, then it is certainly a good idea to reconsider whether you should be making an account there at all. Don’t fret, though – even if you decide 21Dukes Casino isn’t for you at this point, we’ll be keeping a close eye on it and will be sure to update our review as soon as something changes!

Deposits & Withdrawals

As we’ve mentioned before (and as you were probably already aware if you stumbled upon this review), 21Dukes Casino only accepts crypto coins. If you were hoping to deposit using flat currency, through a method like credit cards, pre-paid vouchers (like Paysafecard) or e-wallet, we’re afraid that you’re going to be a bit disappointed.

We at casinoaustraliaonline.com understand that some systems aren’t inherently good or bad – they’re largely up to personal preference. While some of you may be completely disinterested in crypto, others could see it as a big appeal – and that group will be happy to find out 21Dukes Casino deals in a variety of coins. Every casino accepts Bitcoin, but here you’ll also be able to deposit in TRON, Tether, Ethereum and many others.

But that’s not to say the payment options at the casino aren’t without some objective faults. For one, some very big coins (such as DOGE and XRP) are completely missing in action. Furthermore, only two of the aforementioned cryptos can be used for withdrawal: BTC and LITE. This is a huge disadvantage, especially considering how slow BTC is – if you were hoping to withdraw in the much faster ETH, you won’t have that chance at all.

Minimum deposit AU$10
Minimum withdrawal AU$30
Maximum withdrawal Per week – AU$4,000
Deposit methods None
Crypto currencies accepted BTC, BCH, LITE, ETH, TRON, TUSD, USDT
Australian Dollars accepted No – crypto only, but the sum can be converted into Australian dollars upon deposit
Welcome bonus package AU$10,000 + 100 Free Spins

21Dukes Casino Payment Methods

Withdrawal time

There are currently three ways to withdraw your winnings from 21Dukes Casino. Of those, Litecoin is likely the fastest, with transactions happening fairly quickly (after all, that was part of the reason why LITE was created in the first place). As such, you can expect your withdrawal to complete within a day. BTC will be much slower, and those withdrawals will take up to 2-3 days.

There is an alternate way to withdraw if you don’t want to do it using crypto – a bank transfer is also available. However, we can’t recommend this method. Not only would you need to pay AU$29 in transaction fees just to use it, but it’ll also take between 5 and 15 business days for it to arrive. Unless you’ve hit a big jackpot or something like that, there’s really no point in using this slow, costly method over crypto.

VIP Program

Lots of casinos will tell you something along the lines of “we treat our players like VIPs”, but only those with a proper loyalty program can put their money where their mouth is! Some casinos like to give players points that they can exchange for prizes, while others level them up and give them rewards and privileges based on their rank.

Both of those options have their drawbacks, so 21Dukes Casino has gone a different way: it gives every player a guaranteed 15% cashback on all deposits. Let’s say, you deposit AU$70 on Monday, and then another AU$30 on Thursday. The following Monday, you’ll get AU$15 in your account – 15% of the AU$100 total you deposited during the week. This rewards active players without creating a caste system where certain “VIP” players enjoy unfair privileges.

Of course, there’s a caveat to this cashback – you can only get it if you haven’t withdrawn that week. So, in the aforementioned example, if on Saturday you decide to withdraw your winnings, you won’t get a cashback the following Monday. While this is an annoying condition, it’s easy enough to get around, and even with it, it’s hard not to appreciate this fantastic program.

Vip Program at 21Dukes Casino Australia


Pokie tournaments, where players compete against each other over who’ll spin the most pokies under certain conditions (such as a time limit) have found a great deal of popularity lately. Of course, 21Dukes had to join in on the fun – but, much like everything else, it does tournaments a little bit differently.

Tourneys at 21Dukes Casino are called “races”, and they last a grand total of 30 minutes each. This means that, like clockwork, every 30 minutes a new “race” with a new selection of pokies begins as the previous one comes to a close, with the winners being rewarded. Not only does this level the playing field (even if a “high roller” usurps the top spot, you can try again in 30 minutes), but it also incentivizes trying out a whole bunch of different pokies.

But if the tournaments are so numerous, it stands to reason that the prizes wouldn’t be great – and they’re not. All you’ll get if you manage to rank are some free spins, which are welcome, but a far cry from the cash and prizes other casinos offer for their tournaments.


Despite the fact that it deals in crypto (which would ordinarily place it outside many financial legislations), 21Dukes still requires players to verify their accounts before they’re permitted to withdraw any funds. This is done by submitting a number of documents to the support team so that they can confirm your identity and verify that you aren’t using the casino for malicious purposes.

An attempt to withdraw any winnings will automatically trigger the verification process, but you can also do that much earlier by going to the “My Account” section and then selecting “Account Verification”. After that, you’ll be able to upload the necessary documents, such as:

  • Photo ID – This can be your national ID card, driver’s license or passport, any kind of official document that has your name and picture on it;
  • Proof of address – This can be a document that has your name and current address on it, like a utility bill or a recent delivery receipt.

Additional documents may be requested as well. For example, if you used your credit card to purchase crypto, you may be required to provide photos of it to prove that you own it (and haven’t, for example, used a stolen credit card – which some bad actors try to do). You may also need a document from your bank certifying ownership of your bank account.

To check the status of your verification, and whether additional documents have been requested, you can always go to the “Account Verification” section.

Is 21Dukes Casino Legit & safe?

When picking an online casino to play at, it is always important to verify whether it holds a valid license with a certified gaming authority, such as Curacao or Macao. That is because playing at casinos that are not properly licensed is strictly against Australian laws. If you choose to play there, at best you risk your winnings being withheld, and at worst, you may face actual legal trouble.

Unfortunately, we have some bad news. During our investigation, we have determined that 21Dukes Casino is not properly licensed, and as such playing at it as an Australian gambler poses a number of dangers. The lack of license is a huge red flag that should make any player think twice about whether they wish to take the hefty risk of playing there.

Customer support

When you get into trouble on a casino site (for example, your bonus isn’t deposited properly, or some games aren’t working), the customer support will be your best bet at straightening the issues out. As such, having a reliable support team and multiple convenient ways of reaching them is essential for any casino.

At 21Dukes Casino, however, there is only one way to contact them: via e-mail. Popular support options, like live chat, are not supported here, and in our experience, e-mails take hours and sometimes even days to be answered. Obviously, this isn’t at all ideal if you have a time-sensitive issue (like a withdrawal problem) that you need addressed right away.

Mobile casino

Who doesn’t love a good mobile casino? Even if you’re the type of player who primarily likes to play at your computer, we’re willing to bet you’ve spun a few pokies from your phone at least once! If you’re wondering whether that’s possible at 21Dukes Casino, we’ve got good news: the mobile version of the website is actually very well made.

As with most mobile casinos nowadays, you don’t actually need to download any kind of app, all features are directly accessible through the site by opening it via your mobile browser. That will allow you to play games, redeem bonuses, even verify your account! Overall, our impressions of 21Dukes Casino’s mobile version were extremely positive, and we believe most mobile gamblers will be rather satisfied with it.

Can citizens of Australia play at 21Dukes Casino legally?


No. Since 21Dukes Casino doesn’t have a valid license, it is not legal for Aussies to sign up and participate in it. Doing so may result in legal consequences, which is why we can’t recommend that players do so.

Can I deposit at 21Dukes Casino using my credit card?


Not directly, as the casino operates only using cryptocurrencies, and as such does not support bank cards. However, you can use your card to buy crypto, and then use that to deposit.

Are Australian dollars supported at 21Dukes Casino?


Yes. Even though you can’t deposit directly using cash, you can use AU$ to gamble directly at the casino. The site’s interface will also change to natively display bets and bonuses in Australian dollars if that is your preferred currency.

Is it difficult to verify your account at 21Dukes Casino?


No. You can request an account verification at any time by going to the “My Account” section of the site and selection “Account Verification”. After that, you can upload your documents there, and they will be reviewed by the casino staff. Should you be approved, you’ll be able to withdraw without having to go through verification again.

Does 21Dukes Casino support live casino games?


No. Live dealer games are not currently available at the casino. We will keep a close eye on it and amend our review if the situation ever changes.

Can I withdraw my 21Dukes Casino winnings using a bank account?


Yes. You may request a withdrawal using your bank account rather than crypto – however, it carries an AU$29 fee, and will take significantly longer (5-15 business days) for the withdrawal to be completed. We recommend using a crypto wallet to withdraw if at all possible.



It is silly to deny the many positive qualities of 21Dukes Casino. It offers a fantastic selection of pokies, a great set of bonuses (especially the weekly ones you may claim as many times as you want), the big jackpots available and the unique tournaments have all left a great impression on us. On a surface level, it’s easy to see why so many have been drawn to the casino.

However, it is also silly to deny the many downsides of the casino. Lacking a live casino option, or many table games, is one thing – but 21Dukes Casino is also missing essential features, like live chat. You can also only withdraw using 3 different methods (one of which will be a bad choice for most players), and even the deposit methods are a little limited. The worst part is that the casino is completely unlicensed, which makes it a dangerous gamble.

For some, the positives will outweigh the negatives. For us, they did not, and our overall impressions of the casino have been far from stellar. As such, we advise players to think twice before deciding to sign up for it.
