Slots Expert's Opinion

Our slot expert reviews the slot selection, software providers, and how easy it is to browse games. They also look at branded titles, jackpots, and features like tournaments and missions.

What I like:
  • Large and Diverse Slots Portfolio: Duelz has 1600+ slots from leading providers like NetEnt, Play ‘n GO, Pragmatic Play, and Big Time Gaming. This allows for a variety of different themes and types of slots to be offered, catering to all kinds of playing styles and game preferences.
  • Organised Into Categories: The slots are organized into categories such as “Megaways”, “Jackpots”, and “Sticky Wilds”, which helps players quickly find their favourite games.
  • Many Progressive Jackpots: The portfolio includes popular titles such as Mega Moolah, Mega Fortune, and the WowPot series.
  • Mobile-Optimised Play: There is no dedicated mobile app, but the mobile version is smooth and optimised, allowing quick access to games without having to download an app.
What I don't like:
  • No Filter by Provider Option: There is no option to browse games by provider. This limits efficient navigation.
  • No Exclusive Slot Titles: There doesn’t appear to be any exclusive or branded slots offered by the casino, while many competitors feature custom content or studio partnerships.
My recommendations:
  • Introduce Provider Filters: Being able to filter by provider (NetEnt, Pragmatic Play, etc) will increase the overall user experience of the platform.
  • Include a Loyalty or Slots Specific Reward Program: While the duel-based system is unique, adding a more transparent slot loyalty scheme (e.g. points for spins, milestone bonuses, or cashback tiers) would better reward regular slot players who aren’t necessarily engaged in competitive play.

Live and Table Games Expert's Opinion

Our live and table games expert reviews the variety of table games, live dealer quality, and software providers. They also check table limits, usability, and availability, plus extras like bet behind, tournaments, and gamified features like badges and levels.

What I like:
  • Well-Organised Live Casino Section: Duelz Casino boasts an impressive range of live dealer games, with over 90 titles to choose from. There are more than seven different card and dice games to keep things interesting. In addition to all the classic live roulette and blackjack tables, you’ll also find about half a dozen baccarat options – enough to suit all tastes.
  • Top-Notch Titles from Evolution: If you appreciate top-quality games from proven providers, you’ll be pleased to see that Evolution powers more than 30 of Duelz’s live dealer tables. Some of the standout titles include XXXTreme Lightning Roulette, Red Door Roulette, Easy Blackjack, and Always 8 Baccarat, along with crowd-pleasers such as Funky Time and Deal or No Deal.
  • Decent Range of Game Shows: There are around 24 live game shows on offer too, with betting limits ranging from £10 to £5,000, so there’s something for every bankroll. You’ll find all the big names here, including Crazy Time, Monopoly Live, Mega Ball, Cash or Crash, and loads more.
What I don't like:
  • RNG Table Game Options: Although the live casino section is excellent, the RNG table game selection is seriously lacking. The only choices are tucked away in the Arcade section, strangely categorised under table games, which isn’t the easiest to find or the most user-friendly setup.
My recommendations:
  • RNG Game Offerings: RNG table games like roulette and blackjack are still firm favourites among players, thanks to the blend of skill and luck they offer. As it stands, Duelz is lagging behind the competition when it comes to these virtual options. Increasing the RNG offering would definitely make the casino more appealing to a wider audience.

Social Media Expert's Opinion

Our social media expert checks which platforms the company uses, how often they post, and how well their content performs. They also look at follower count, brand tone, growth, and whether any channels are inactive or missing.

What I like:
  • Potential for Engagement on YouTube: Despite having only 1.12K subscribers on YouTube and being less active, Duelz Casino has had video views ranging between 30K and 600K. This suggests that the brand's channel has significant potential to grow.
  • Decent Facebook Following: Although the casino's Facebook account has been virtually inactive since 2019, it still has a respectable following of 3.7K. Duelz used to post news about the latest games on the platform, slot tournaments, and more.
  • Brand Voice and Gamification: Duelz Casino's gamification features were previously effective in keeping players engaged. They resonate with the brand's target audience and offer a rather unique characteristic that sets the platform apart in a highly competitive market.
What I don't like:
  • Inactivity Across Most Platforms: The inactivity on Facebook and Instagram, coupled with the sporadic activity on YouTube, clearly indicates that social media is not a priority for the brand. Potential players could see this as a red flag, especially in today's highly digital landscape.
  • No TikTok, X, or LinkedIn: In addition to underutilising its already existing social media accounts, Duelz is not present on TikTok, X, and LinkedIn. Vastly different, the three platforms provide opportunities for engagement of both players and potential business partners.
My recommendations:
  • Regular Posting Schedule: Consistent posting schedule across all platforms will help Duelz stay relevant and top-of-mind for users. To make it easier, the brand could repurpose its content to use it on all its social media channels (if appropriate, of course).
  • Highlight Unique Brand Traits: Duelz could use its unique brand traits and features to re-engage its audience across different social media platforms. Using interactive content and fostering a sense of community could go a long way in boosting player loyalty.

Legal Expert's Opinion

Our legal expert checks if the casino is licensed and since when. They review the terms to see if bonus abuse is clearly defined and flag vague or misleading clauses. The review also covers player protection, responsible gambling tools, ADR, GDPR compliance, and regulatory fines.

What I like:
  • Licensing and Regulation: SuprPlay Limited operates Duelz Casino and holds a valid UK Gambling Commission licence (Licence No. 48695, issued 27 September 2017). It is also licensed by the Malta Gaming Authority (Licence No. MGA/B2C/325/2016, issued 8 July 2016). No regulatory actions are recorded against the operator.
  • Clear Bonus Abuse Terms: The General Terms & Conditions explicitly prohibit bonus abuse. Section 12 of the separate Bonus Policy provides clear examples of what constitutes such, providing transparency for players.
  • ADR Compliance: The platform provides a clear Alternative Dispute Resolution (ADR) process through eCOGRA, an independent body that can adjudicate disputes. Section 9 of the T&C outlines the Complaints & Dispute Resolution Procedure.
  • Responsible Gambling: The platform provides comprehensive responsible gambling tools. These tools align with UKGC requirements and are detailed in both the Responsible Gambling Policy and General T&Cs (Section 7).
  • GDPR Compliance: Duelz complies with GDPR, as evidenced by its clear and detailed Privacy Policy. It outlines player rights and data protection practices transparently.
What I don't like:
  • Ambiguous "Fraudulent Activity" Definitions: Section 11.11 of the General T&Cs prohibits "fraudulent activity" without defining actionable metrics (e.g., win/loss ratios, VPN detection thresholds). Penalties like account closure lack clear appeal pathways.
  • Limited Self-Help Resources: At the time of review, Duelz does not provide an FAQ section, which could make it harder for players to resolve common queries themselves quickly. Players must rely on live chat for support.
My recommendations:
  • Clarify Fraud Metrics: Amend T&C section 11.11 to specify "fraudulent activity" using measurable criteria (e.g., win/loss ratios exceeding 1:5, IP/VPN mismatch detection) to reduce subjective enforcement.
  • Enhance Content Usability: Introduce a comprehensive FAQ section in plain language. This could make it easier for players to understand key terms relating to bonuses, withdrawals, and verification, without navigating extensive T&C texts.

IT Expert's Opinion

Our IT expert evaluates the site’s technical performance, covering security, HTTPS implementation, and core web metrics. They also check mobile optimization and the use of content delivery networks. Further review includes caching practices, hosting setup, and frontend diagnostics.

What Works Well
  • Excellent Core Performance Metrics: The site demonstrates strong performance in key user-centric metrics. It achieves a First Contentful Paint (FCP) of 0.4s, a Largest Contentful Paint (LCP) of 1.0s, a Speed Index of 1.2s, and becomes interactive (TTI) in 2.0s.
  • Low Interactivity Delay: The Total Blocking Time (TBT) is exceptionally low at 90ms, indicating a responsive user experience with minimal delay after content is rendered.
  • Secure Implementation: The site correctly uses HTTPS, ensuring that all data transmitted between the user and the server is encrypted and secure.
  • Mobile-Optimized Viewport: A comprehensive viewport meta tag (initial-scale=1,maximum-scale=1,minimum-scale=1,width=device-width,user-scalable=no,minimal-ui,viewport-fit=cover) is properly configured, ensuring an optimized layout for mobile devices.
  • Error-Free Console: No browser errors were logged during the audit, suggesting a clean and stable front-end implementation.
  • Modern Web Practices: The site is built as a Progressive Web App (PWA) and utilizes modern performance techniques like Priority Hints. It also employs Sentry for issue tracking and Cloudflare Browser Insights for Real User Monitoring (RUM).
  • CDN for Libraries: The site leverages Google Hosted Libraries, which serves common JavaScript files via a CDN, helping to reduce load times for those specific assets.
What Needs Improvement
  • High Cumulative Layout Shift (CLS): The CLS score is 0.223, which is significantly higher than the recommended threshold of 0.1. This indicates that users experience disruptive visual instability as page elements move unexpectedly during load.
  • Third-Party Cookie Usage: The site was found to use a third-party cookie (slfp from scripts.prdredir.com). This poses a risk as browsers phase out third-party cookies, which could lead to broken functionality in the future.
  • High Potential for Input Delay: The Max Potential First Input Delay (MPFID) is 230ms. This suggests a long-running task on the main thread that could make the site feel sluggish if a user tries to interact with it at a critical moment.
  • Slow Server Response Time: The initial server response time (Time to First Byte) for the root document was 520ms. While the overall performance scores are good, this initial delay adds unnecessary time to every other performance metric.
  • Outdated JavaScript Framework: The site is built using AngularJS, a legacy framework that is no longer in long-term support. This can introduce performance bottlenecks, security risks, and increase maintenance overhead.
  • Missing Structured Data: No schema.org structured data was detected. This is a missed SEO opportunity to help search engines understand the site's content and qualify for rich results.
  • No Defined Caching Strategy: The analysis did not detect a specific sitewide caching layer, which is crucial for delivering fast, repeatable experiences for returning visitors.
Recommendations
  • Prioritize Fixing CLS: Action: Identify and stabilize the elements causing the 0.223 layout shift.
    Technical Detail: Use browser developer tools to pinpoint shifting elements. Ensure all images, iframes, and ads have explicit width and height attributes or use CSS aspect-ratio to reserve space before they load.
  • Optimize Main Thread and Reduce MPFID: Action: Break down the long task causing the 230ms Max Potential FID.
    Technical Detail: Profile the page load to identify the specific JavaScript function causing the long task. Given the use of AngularJS, investigate heavy data-binding or complex digest cycles. Defer non-critical JavaScript execution and consider a long-term migration strategy away from AngularJS to a modern framework (e.g., React, Vue, or a newer version of Angular) for better performance and maintainability.
  • Improve Server Response Time (TTFB): Action: Reduce the 520ms TTFB to under 200ms.
    Technical Detail: Implement server-side optimizations such as full-page caching for anonymous users and object caching (e.g., Redis, Memcached) for database queries and API responses. Analyze and optimize backend code and database performance.
  • Implement a Comprehensive Caching and CDN Strategy: Action: Deploy a full-site Content Delivery Network (CDN) and establish a clear caching policy.
    Technical Detail: Go beyond Google Hosted Libraries and configure a CDN (like Cloudflare, Fastly, etc.) for all static assets (CSS, JS, images, fonts). Set aggressive Cache-Control headers for static resources to leverage browser caching effectively and reduce server load.
  • Implement Structured Data (Schema.org): Action: Add structured data markup to key pages.
    Technical Detail: For a casino site, implement Organization and WebSite schema on all pages. For game pages, use Game or SoftwareApplication schema to provide detailed information to search engines, which can improve search appearance.
  • Phase Out Third-Party Cookies: Action: Audit and replace the functionality tied to the slfp third-party cookie.
    Technical Detail: Investigate the purpose of this cookie. If it's for analytics or retargeting, explore privacy-centric, first-party alternatives or server-to-server tracking methods to ensure future compatibility with all browsers.

Lead Author's Summary and Final Rating

Momchil ChonovGambling Expert & Content Team Lead
Very High Overal Expert Score 8.0/10 or 80 %

After reviewing Duelz Casino in depth and considering the views of my team of experts, I think this site stands out for its selection of over 1,600 slots from top providers and an impressive range of live dealer tables, particularly by Evolution. The licensing and responsible gambling features provide valuable peace of mind, while easy navigation through organised categories and plenty of jackpots make it an appealing choice for UK players.

On the flip side, the unclear “fraudulent activity” wording in the T&Cs, a rather basic RNG table game offering, and the lack of an FAQ could frustrate users. Social media engagement is minimal, and there are some technical areas needing attention, such as layout shift and an outdated framework. Overall, the positives are significant, but Duelz could push even higher with clearer policies, more games, and a bit more upkeep behind the scenes.
