21 Dukes review

Does 21 Dukes Casino offer a welcome bonus?

21 Dukes Casino lists a welcome package of 200%-300% across your first, second, and third deposits, plus 25 free spins.

What are the terms & conditions of this bonus?

Their description of the bonus is unclear and we could not find the full bonus terms, so would not recommend pursuing this offer. 

Here are some conditions we found through a third party website, as we could not confirm these details from information provided by 21 Dukes:

• The free spins are subject to a 35x wagering requirement.

• Players have seven days to complete the wagering requirement.

Other bonuses for new and existing players

The 21 Dukes website lists a handful of other promotions, but none of them are particularly clear. 

Their bonus page describes a crypto bonus and a no deposit bonus, but does not list the full terms for any of them. There is no indication of wagering requirements, timeframes or eligible games for either of the above promotions. 

We could not find the full terms and conditions for 21 Dukes Casino anywhere on their website. 

At CasinoTopsOnline we do not recommend participating in any promotions with such unclear terms, especially from a casino with no gambling licence.

Where is 21 Dukes Casino licensed and available?

The 21 Dukes Casino website declares itself to be an “established online casino”.

After some looking around, we discovered that they have only ever held a Costa Rica licence.

This is not a gambling licence - it’s a business licence.

By their own website’s admission, the Costa Rica licence “...provides regulatory oversight, though players should note that this jurisdiction offers less stringent player protections than some European regulators…”

Some sources state that 21 Dukes holds a Curaçao licence, but we could not find any claims to this on their website or through the Curaçao Gaming Authority.

Is 21 Dukes Casino safe and trustworthy?

At CasinoTopsOnline, we believe users should only visit casinos with a strong reputation for safety.

We would not recommend visiting any casino with unclear licensing, as it could leave you vulnerable to unfair business practices.

21 Dukes Casino has received a lot of complaints regarding withheld funds and account closures. 

For these reasons, we would not recommend visiting 21 Dukes Casino.

Safety and security

The 21 Dukes site is SSL encrypted. We could not find any issues with the security of their website’s structure.

KYC and withdrawals

The 21 Dukes Casino website informs players that their Know Your Customer (KYC) checks involve submitting a copy of your ID, passport or driving licence.

Their page states that this process typically takes 24-48 hours after the documents are submitted. Many players report lengthy processing times, sometimes over a week.

21 Dukes Casino has multiple allegations of withholding funds from customers.

What other players & reviewers say

Reviews of 21 Dukes Casino are broadly negative, and customers on trusted review platforms seem to reach the same consensus.

21 Dukes reportedly cancel withdrawals for a number of unclear reasons.

One user’s account was approved before they were told their

“...withdrawal was denied because of a ‘random’ account verification process.”

Another reported their account was closed after an apparently successful withdrawal. Neither customer received their money. 

Another customer was unhappy with their unclear bonus terms. They waited eight days for their withdrawal, only to have it cancelled as they’d breached their policy. 

The user remarks that

“...you do not get a warning you should not make bets above 5 but they give [you] the option to bet higher… then void all winnings”. 

A site-level restriction, or at least clearer bonus terms, would help users avoid this trap, which this user deems unfair. 

21 Dukes has not publicly responded to any negative comments.

All of 21 Dukes’ game providers are listed at the footer of the page. There are a lot of the most popular providers but they are missing some, such as Playtech.

RTP transparency

We could not find any RTP information on the 21 Dukes website.

Payment methods at 21 Dukes Casino

Fees, high minimum withdrawals and long waits for approval are just some of the issues customers report from 21 Dukes Casino.

We could not find any options for transfers of fiat currencies outside of bank transfers, which carry high flat fees and a staggering minimum withdrawal of $500.

Method	Fees	Min Deposit	Payout Time	Issues
Bank transfer	€23	$10	Up to 5 days for review, then 5-7 days	Minimum withdrawal of $500
Crypto	No fees	$10	Up to 5 days for review, then instant	Long wait for approval, $30 minimum withdrawal.

The 21 Dukes website loads quickly on mobile, but there are some flaws with how it is displayed. We ran a page analysis and here’s what we found:

Things that work ✅:

• Fast loading speed

• Does not request geodata or notification permission

Things that don’t work so well 🔧:

Customer support at 21 Dukes Casino

Our experience of customer support at 21 Dukes Casino left a lot to be desired. There has never been a live chat option, or even a phone line. Disgruntled users must contact [email protected].

Responsible gambling tools

The 21 Dukes website lists very limited responsible gambling tools:

• Deposit limits: players can set daily, weekly and monthly restrictions on deposits

• Self-exclusion: Users can set temporary or permanent suspensions on their account, but this must be requested through support.
