About Duelz Casino

Duelz Casino, founded in 2018, is a unique gambling experience brought to us by SuprPlay Ltd, the name behind Voodoo Dreams, and labelled by their own team as ‘A Truly Magical Casino’. Duelz offers something unique that other brands in the family don’t have – the ability to ‘duel’ against other players on a simple 3×1 slot for prizes including bonues and cash. This gamification feature along with their huge slots catalogue make Duelz a good choice for UK slots players.

What We Liked

  • Totally unique duelling feature to earn rewards
  • Big slots selection – over 1,500 in total
  • 100 Book of Dead spins in sign up offer
  • Fun, immersive website theme
  • Good customer support with quick response time

What We Didn't like

Sign Up Offer 8/10

  • 100% Match Up To £100
  • 100 Bonus Spins on Book of Dead (20 per day for five days)

This is a good bonus package with the caveat that the threshold to qualify is £20, so if you are thinking of depositing less than that then you should try elsewhere if you want some free play. For example, you can claim a 100% match from just £10 at Casumo and BacanaPlay right now.  At the other end of the scale, the £100 cap on the bonus will be enough for most, but if you are looking to deposit more then you could try Dream Vegas (get 100% up to £300) or Temple Nile (get 100% up to £500).

The wagering requirements are 30x the sum of bonus PLUS deposit which is high. If you deposit £20 and claim a £20 bonus you will need to wager £1,200 before you can withdraw any winnings. Bonus winnings also have a £500 cap. For less tight wagering requirements you could try Luckland (40x bonus ONLY) or PlayGrand (35x bonus ONLY).

An advantage of this deal is that it gets you 100 spins on Play n Go’s Book of Dead slot which is a top-quality high variance slot. But I noticed that the wagering requirements for winnings generated from your free spins are set at 45x. That is quite high – for a better deal you can always try SuprPlay’s other site, Voodoo Dreams, where you get 50 Book of Dead spins with winnings paid out in real cash.

Here is how the Duelz Casino sign up bonus compares with others in the UK right now.

Website UX & Registration 8/10

Slots players familiar with other SuprPlay sites, NY Spins and Voodoo Dreams, will be at home at Duelz Casino as it runs on the same platform. The website uses the same layout with navigation in a side bar down the left of the screen and the main game menu in the center area.

This is an immersive brand meaning the design reflects the casino’s theme which is one of ‘duelling’ with other players to see who can score the most slots wins in a 1v1 battle. A shield in the logo reflects this as does a cartoon meadow strewn with diamonds and other trophies on the home page.  You will also notice that when the game menu comes up, the backdrop changes to a kind of medieval dungeon with stone walls and a skeleton chained to the wall. That is the arena in which your ‘dueling’ takes place.

Duelz Casino Home Page
Duelz Casino Home Page

The overall vibe is a kind of fantasy dungeons and dragons role play one. You choose your own avatar and make friends to do battle with. The imagery looks nice and makes Duelz stand out from the crowd. However, at times it did make it hard to read some of the game logos when scanning the menu.

Finding Important Information

To find out more about Duelz and how it works you can browse through pages of important information by clicking links in the footer. You can read up on the Bonus Policy under ‘Duelz Bonuses and How They Work’, find out more about the Dueling feature under ‘What Is Duelz?’ and scan the usual terms and conditions for withdrawal information. Everything is easy to locate and clearly described.


Registration is very easy at Duelz. They say it should take under 60 seconds but for me it took probably more like 90. No complaints though – it is easy to follow thanks to a 3-step form that appears in a pop-up window shown in our screen shot below. As with most casinos, initial verification checks are done behind the scenes and you can deposit and play without submitting any documents.

Registration is a 3-step process completed in under 90 seconds

Account Pages

Once you are logged in, to access your account page you’ll need to hit the avatar link above your name on the left of the screen. It may take a few minutes to orientate yourself here as Duelz mixes up its normal account functions with the bespoke features of the site. You’ll therefore find Pending Withdrawals, Verification and Responsible Gambling tools next to The Locker Room where you choose your avatar. It’s a little confusing at first but you will soon get used to it.

What is important to know is that to deposit and withdraw you have to access a seperate area through the green ‘Deposit’ link. This bit is really easy to use and nicely designed. Your latest payment service is saved but you can easily jump to another using the logos at the bottom of the screen.

Altogether, Duelz is a fun site to use, whether you want to go all in, set up an avatar and take part in duelling or simply play slots as you do anywhere else. Information was clear and informative and finding what we were looking for was never a problem.

Online Slots 8/10

Catalogue and Game Providers

Slots are what we are here for and Duelz Casino delivers in style. In total close to 1,500 slot games are available, provided by 90 different suppliers.

That means whatever your tastes are, there should be something for you. A few minutes browsing the menu reveals that some of our favourite game studios are contributing to the action, including  No Limit City, everyone’s high variance favourites, Big Time Gaming, and a long list of other game suppliers including Hacksaw Gaming, Relax Gaming, ELK Studios, Thunderkick, Blueprint Gaming and Yggdrasil.

Duelz Casino Game Menu
Browsing the slots at Duelz Casino

Jackpot Slots

The Jackpot tab shows 44 games. This is not the biggest selection – you will find more at Casumo (250+) or Play OJO (367) for example. It does include progressive jackpot classics like the Mega Moolah and Wow Pot series from Microgaming. However, there were no Dream Drop Jackpots (Relax Gaming), Jackpot King (Blueprint Gaming) or Mega Fortune Jackpots (NetEnt). Nor do Red Tiger’s Must Drop games appear anywhere.

New Slots

Duelz Casino keep their ‘New’ selection up to date. There were more than 50 games in the list when we checked, including Happy Apples (Red Tiger), Stormforged (Hacksaw Gaming) and Countess Cash (Gold Coin Studios), all released within 14 days of our review.

Megaways Slots

At Duelz Casino there is a special Megaways tab to browse games with Big Time Gaming’s expanding reels game engine. There are 65 titles listed including Big Bass Bonanza Megaways, Gonzo’s Quest Megaways and Fruit Shop Megaways.

This is a good selection but if you want more choice you could try Casumo with 176 Megaways titles or Yako Casino from L and L Europe with more than 120 Megaways games.

Slingo Games

Duelz Casino does not have any Slingo games in its catalogue. If you want to play Slingo then try our list of Slingo Sites instead.

Game Menu, Search Functions and Game Window

The game menu is simple to navigate, bringing up the latest or most popular games at the top and allowing you to filter by type – new, jackpot, drop and win, Megaways – or search by specific title. These are important options when it comes to a huge catalogue like this one. However, there is no option for more sophisticated searches by game supplier, RTP, paylines or game feature for example. So exploring the catalogue in more depth is not easy.

A nice feature of Duelz Casino is that the slots load up in the same window as the main site, so you retain the navigation down the left side. Whilst this is helpful and keeps you grounded, beware that clicking one of the links there – deposit for example – will close-down your current game.

Slots RTP Settings at Duelz Casino

Many slot providers now offer their games to casinos with more than one RTP setting. It is at the discretion of the casino operator to choose which setting to run the games at. In our review process for each slot site we check the RTP settings of up to 10 games we know have more than one RTP option.

Here is what we found at Duelz Casino.

Razor SharkRed Tiger96.70%, 95.05%, 90.52%96.70%

NOTE: These settings were verified on 22nd May 2023.

From this small sample it is clear that Duelz are choosing to run some games, in particular Play n Go slots, at low RTP settings. This means that the return on your wagering may be lower on these games than at other sites. If RTP is important to you then this is something to consider. We recommend MrQ where every game we verified was running at the maximum RTP.

Find out more about RTP in our explainer guide.

Live Dealer 7/10

The live suite at Duelz Casino is provided by the industry-leaders Evolution Gaming and it provides a big mix of card, dice and roulette tables, plus their unique gameshow series that are particularly suited to slots players looking to make a move towards live dealer.

The advantage of the Evolution Gaming lobby is that there are 10,000s of players online at any time because the action is pooled from 100s of casinos so the tables are always busy. That means lots of choice with over 100 Blackjack tables, more than 20 Roulettes, as well as Sicbo, Poker and Gameshows like Crazy Time and Dream Catcher.

Evolution offer a big choice but if you prefer a wider choice of tables from providers like Pragmatic Play and Playtech for example, then you will need to look at a site like Betfred or Spin Rio.

Here is a summary of the games available in the Evolution Gaming live lobby. The number of tables may vary depending on the time of day and day of week.

Loyalty Promotions 7/10

Duelz offers a few regular promotions to its players including a 10% weekly cashback – credited each Friday to those who have wagered during the week.

However, the main event here is duels and tournaments. These set Duelz apart from its competitors. Duelling allows you to take on other players on the site who are online at the same time as you. It’s easy to do and quite un-intrusive so you can switch if off if you don’t want to take part.

The winner of any duel is awarded points for their hard work. Collect enough and you can swap them for Treasure Chests which reveal cash prizes and bonuses. As you collect Treasure Chests you will also move further up the leaderboards displayed on the site, unlocking extra rewards at each level.

It’s a classic gamified loyalty program, the kind you also find on sites like Casumo and it adds another layer of fun to the Duelz experience.

We entered a Duel ourselves to see how it worked. Here is what happened:

We picked our own avatar – a Wizard character

We picked an arena to fight in– the Iron Dungeon

We chose 5 spells – lightning, strength, illusion, healing, mirror

The Duel began.

We played the duel on a simple 3×1 slot with cards for each position on the reel. You spin, they turn and reveal Jack to Ace symbols, or picture symbols with payouts of 2x to 100x. The duel lasted around 10 minutes. You have your cash balance and your Health Points balance, starting at 75,000. As you win and lose, and so does your opponent, your HP balance goes up and down and your spells help to protect you and damage your opponent.

Dueling at Duelz Casino
The dueling feature at Duelz Casino

We won our duel by finishing with more HP than our opponent. That unlocked a chest with points and valuables to help in our next duel. And we levelled-up as well off the back of it as you can see in our screen shot.

Overall, the experience was fun, but quite time consuming. I guess if you played every day you’d get into it, especially with the leaderboards to keep track of. And it is certainly an original format for a casino loyalty feature.

Cashier Options 7/10

The options for funding at Duelz include debit cards, eWallets and prepaid cards. This is a good selection with the caveat that the minimum deposit is £20 here, with the exception of Trustly which is £10, and if you use either Neteller or Skrill then you won’t be eligible to receive the sign-up offer.

There is also a 2.5% fee that comes with deposits made with Mastercard and Visa in the UK which is unusual.

Here are the deposit and withdrawal options with fees and processing times.

Payout Speed 8/10

I tested the withdrawal process at Duelz Casino. I made a withdrawal or £20 to Paypal on a Monday morning at 09.00am.

Customer Support 8/10

Duelz Casino run a 24/7 support service on live chat and email. So, even if you are playing through the night then you can speak to someone on the team if you have an issue. There is no phone support however.

I have found the support service at this casino to be very quick to respond, whatever time I contact them. in most cases the first response to a live chat query is under 2 minutes, often in 30 seconds. You speak directly to a support agent, NOT an AI bot, and they are knowledgable and helpful.

The service could be improved by supplementing the live chat with an FAQs page with answers to common questions. Almost all casinos have this, except for Duelz.

KYC Process 9/10

At Duelz, if you receive a request to send ID documents to verify your ID then you can easily do this by using the verification area in your account. SuprPlay have outsourced this part of their operation to Hooyu.com. This is becoming more commonplace now – Hooyu is also used by Betfred Games and the L and L Europe slot sites like Pub Casino and All British Casino.

I had some issues getting the photo IDs recognised, and it took 10 minutes to submit documents, but after that they were approved in under a minute. This is much quicker than submitting documents on email for a manual check from customer support.

You can see the Hooyoo interface in the screen shot below.

License & Reputation 8/10

Duelz is owned and operated by SuprPlay Ltd, a company registered in the jurisdiction of Malta and licensed by the UK Gambling Commission and Malta Gaming Authority.

This is their licensing information.

SuprPlay Ltd operate three slot sites under their UK Gambing Commission license – Voodoo Dreams, Duelz and NYSpins.

Regulatory Action

At time of writing there has been no regulatory action against SuprPlay Ltd.

Consumer Reviews Across The Web

Duelz Casino has an average rating of 1.8/5 on Trustpilot from 181 reviews.

Complaints mainly relate to slow withdrawals caused by delays in account verification or the high wagering requirements and £100 max win limit that come with the free spins offer. Duelz now use the Hooyu account verification system that allows you to upload documents and have them approved in under 1 hour so this process should be significantly easier than it was previously and there should be no delay to your withdrawals. Regarding the wagering requirements. They ARE tight here – 30x on bonus AND deposit. It’s something to consider before you take up the offer.

We also found some complaints on the popular Casinomeister forum regarding the low RTP settings on some slots which we raised earlier in our own review. If RTP settings are a big deal for you then we recommend you browse our lists for an alternative slot site.

Our Verdict 7.8/10

Duelz is a smart casino from one of the smaller operators working in the UK. They don’t have the same profile as White Hat Gaming or Skill on Net but SuprPlay know how to entertain and if you’ve played at either Voodoo Dreams of NY Spins and enjoyed it then you’ll find Duelz to your taste too. The site theme is original, there is a competitive range of games, and the gamification features provide a point of difference that is compelling in the crowded UK market.

If you are considering playing here then you should weigh up these positives against the 2.5% debit card fees, curiously small progressive jackpot offering and low RTP settings. If you can live with those then Duelz is a great choice for your next slots adventure.
