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:
Enjoy Rainbow Riches Slots:
If you cannot get enough of Barcrest's Rainbow Riches franchise of online slots, then Rainbow Riches Casino is perfect, obviously. Besides the classic video slot, themed on Irish Luck, try Rainbow Riches Pick n' Mix, Daily Rainbows, or Slingo Rainbow Riches.
Optional Jackpot Blasts:
If you love progressive jackpots, then the Jackpot Blasts at Rainbow Riches will be right up your alley. Just opt in on any qualifying slot, pay 10p per spin, and you'll be in with the chance of winning one of four jackpots: mini, minor, major, and mega. You can even win when playing non-jackpot slots such as the classic Rainbow Riches.
Important Slot Information Provided:
When you click on any slot, information is provided on how to play the game and its key features. Additionally, the theme of the slot is covered, and the process of triggering the bonus round is also described. This information is decent, especially when looking to play something fresh.
Daily Free Games:
After your first deposit, you'll qualify to play the Daily Free Game, where you can win free spins or free bets on a wide range of slots. To win, just reveal matching symbols on a grid. The top prize is £750. Also, if you are lucky and win a prize, no wagering requirements apply.
Highly Rated iOS and Android Apps:
Many players love playing slots on both Android and iOS devices. The quality is top-notch, buffering never occurs, and the graphics are in HD. On the App Store, the Rainbow Riches app is rated 4.7/5, and on the Google Play Store, it is rated 4.6/5.
What I don't like:
Small Slot Library:
Although the library primarily focuses on Rainbow Riches slots, the total count is modest. There are only about 340+ to choose from and filtering them isn't simple. Compared to other online casinos with thousands of slots, such as Unibet or Grand Ivy, 340 is on the small side.
Jackpot Blast Additional Cost:
When you play any Jackpot Blast, you must pay an additional cost to play (10p per spin). This is unlike other jackpot networks that pay out four prizes, such as Wowpots, Jackpot Kings, or Hold & Wins.
My recommendations:
More Megaways Slots Added:
Everyone loves playing Megaways slots, as the gameplay is fun and there are many ways to win. Granted, Rainbow Riches covered its namesake with Megaways slots, but adding more titles wouldn't go amiss. Preferably, new ones could be added every week to keep the library fresh and add to the small number of slots already on offer.
Add a "For You" Section:
A "For You" section could be created to recommend games from your previous plays. This will always give players game ideas, so things do not get repetitive. The slots section could even go a step further and offer the most popular slots category in the UK, so you can see what others are playing.
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:
Niche Live Games Available:
Unlike other operators that lack other types of live table games, Rainbow Riches steps ahead, offering even more games like baccarat, craps, and poker. The operator's live casino section also includes popular game shows like Deal or No Deal, Crazy Time, and more.
Live Casino Cashback Bonus:
Simply register for an account, deposit £10, and input the promo code: SIGNATURE. Then, play with the £50 on Blackjack Signature, and you'll qualify for £10 cashback. This is good, as live dealer bonuses are rare in the UK.
Attractive RNG Blackjack Versions:
Rainbow Riches offers a selection of over 14 RNG blackjack games, and although the selection is not the biggest in class, it features several attractive versions. Notable titles here are games like 9 Up Blackjack, Atlantic City Blackjack High Stakes, and Blazing 7s Blackjack. Yet another very attractive option is Phoenix Blackjack – a game with an accumulated jackpot.
Decent Range of RNG Roulette Games:
The list of RNG roulette games offers a relatively good diversity, with interesting options like 100/1 Roulette, 20p Roulette, High Stakes Roulette, and others. The betting limits range between £0.10 and £5000, meaning that players with different budgets can find suitable titles.
What I don't like:
Limited Number of Live Games:
The number of live titles is rather limited, with just about 32 offered on the site. Granted, you can play most types of live games, such as baccarat, blackjack, roulette, and game shows, but I'd like to see more titles added. Rainbow Riches is already supplied by Evolution, so it should be easy to add more of their games to the library.
No Filtering Options:
When you click on live games, everything the site has to offer is lumped together. I'd like to see this at least separated by the game type, such as roulette, game show, blackjack, etc. Even further, Rainbow Riches could offer filters like RTP, game provider, and minimum bet.
My recommendations:
Improving the Live Casino Offerings:
While Rainbow Riches offers some popular live game shows, some of the most popular live roulette and blackjack options by reputable software brands are not included. In my opinion, the operator can do better in filling its live casino lobby with more games from market-leading software studios to stay competitive.
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:
Opportunity to Build a Distinct Identity:
Having no official social media presence, Rainbow Riches Casino has the opportunity to develop a distinct identity. In this case, there's also a substantial challenge considering other brands with similar names – e.g., the Rainbow Riches slot series.
Potential for Engaging Content:
As suggested by its name, Rainbow Riches Casino is very much focused on slots. This can be utilised through reviews and interesting news on the topic. The operator offers sports betting, so sports news and predictions could also be helpful.
What I don't like:
No Official Social Media Platforms:
The inactivity on major platforms like Instagram, X, Facebook, and YouTube is a missed opportunity for Rainbow Riches to engage directly with players and grow a community around the casino.
Brand Confusion with Other Profiles:
Due to the popularity of the Rainbow Riches slot games, there are many similar profiles with the same name. This creates confusion, making it harder for the casino to stand out and establish an official, recognisable presence.
My recommendations:
Establish Official and Verified Accounts:
Rainbow Riches Casino could start small with just a couple of bigger platforms, such as Instagram and Facebook. The social media team should verify the operator's official accounts and pages and include them on the site for credibility.
Focus on Niche Content and Community Building:
Instead of competing with other Rainbow Riches profiles, the casino can focus on niche content, such as casino tips, promotions, and responsible gambling messaging. The content is engaging and frequent at other online casinos like NetBet.
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:
Comprehensive Complaints Policy:
Rainbow Riches details its complaints procedure in its FAQ section and directly links the policy within the Terms and Conditions (Section 15.6). The process is broken down into clear steps, outlining the timescales and relevant contact details. ADR is provided by eCOGRA, offering an independent review of unresolved complaints.
High Standard of Data Protection and GDPR Compliance:
The Privacy Policy is detailed and up to date, referencing ISO 27001 certification, compliance with GDPR and UK Data Protection Act, and laying out user rights to data access, erasure, and objection in plain language.
Medium Protection Level for Customer Funds:
Player balances are kept in a segregated client account, separate from operating accounts, meaning that in insolvency, customers have a reasonable chance of recovery. Many casinos offer only the minimum (not protected), so this is a significant advantage for Rainbow Riches Casino users.
UK Licensing and Regulation:
Rainbow Riches Casino is operated by Gamesys Operations Limited, which holds an active UKGC licence (Licence No. 38905, issued 1 November 2014). The platform is also regulated in Gibraltar and Ireland.
What I don't like:
Complexity and Length of Terms:
The site's policies are lengthy and highly detailed, cross-referencing multiple rules, definitions, and promotional conditions. This can increase the difficulty for average players in identifying relevant rights and obligations, potentially leading to misunderstandings if policies are not read in full or navigated carefully.
Potentially Ambiguous Discretionary Clauses:
Several sections, especially regarding account closure, bonus forfeiture, or voiding of winnings, grant the operator broad "reasonable evidence" or "sole discretion" powers. While regulatory compliance may require flexibility, this language could be interpreted or executed with minimal transparency for affected players.
Previous Regulatory Sanctions:
In November 2023, Gamesys was fined £6 million by the Gambling Commission for failures in anti-money laundering and social responsibility processes. The company received an official warning, with additional conditions attached to its licence.
My recommendations:
Clarify Account Restriction and Discretion Terms:
The operator should revise the language of its discretionary powers, especially regarding account closures and withholding of funds. Adding clearer examples or thresholds for "reasonable evidence" of a breach or fraud would help users understand boundaries and reduce the risk of arbitrary action.
Improve User Accessibility of Key Policies:
Condensing the Terms and Conditions and adding accessible, user-friendly summaries would help users navigate and understand key points.
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 optimisation and the use of content delivery networks. Further review includes caching practices, hosting setup, and frontend diagnostics.
What Works Well
Exceptional Performance & Core Web Vitals:
The site is extremely fast, responsive, and provides an excellent user experience.
Server Response Time: A blazing-fast 90 ms.
First Contentful Paint (FCP): 0.6 s.
Largest Contentful Paint (LCP): 1.7 s.
Time to Interactive (TTI): 1.7 s
Total Blocking Time (TBT): A near-perfect 10 ms, indicating no blocking of the main thread.
Cumulative Layout Shift (CLS): An excellent score of 0.045, signifying a visually stable layout.
Modern Infrastructure & Privacy:
The site runs on a high-performance Node.js/Express stack with an Envoy reverse proxy.
The analysis found that the site avoids third-party cookies, which is a major positive for user privacy.
Solid Foundational Setup:
The site has HSTS enabled for security and a correctly configured mobile viewport (width=device-width, initial-scale=1.0). The technology stack includes Preact and styled-components.
What Needs Improvement
CRITICAL - Mixed Content Security Vulnerability:
The site is not fully secure. It attempts to load a resource over an insecure protocol (http://www.rainbowrichescasino.com:443/registration/account). This request is blocked by the browser and logged as a "Mixed Content" error, creating a security risk.
Critical Application Errors:
The browser console logs multiple errors, indicating significant application health issues.
WebSocket Connection Failure: he site fails to establish a WebSocket connection to wss://bingo-connection-proxy.prd00.iedu.ballys.tech:8443. Errors include CORS policy violations and a failure to establish a tunnel via the proxy server (net::ERR_FAILED).
No CDN Detected:
The site does not appear to leverage a Content Delivery Network, which is a missed opportunity for optimizing global asset delivery and resilience.
Missing SEO Elements:
No structured data (schema.org types) was found in the analysis.
My recommendations:
Immediate Action - Resolve Mixed Content Security Flaw:
This is the highest priority. The insecure request to http://.../registration/account must be fixed immediately.
Action: Locate the code making this request and change the protocol from http to https://. Enforcing HTTPS for all resources is non-negotiable for site security.
Fix WebSocket Connection Errors:
The recurring WebSocket failures are a critical bug. The error message "Establishing a tunnel via proxy server failed" strongly points to a misconfiguration in the Envoy proxy.
Action: Review the Envoy proxy configuration to ensure it is correctly configured to handle and upgrade secure WebSocket (wss://) connections. Additionally, verify that the CORS policy on the target ballys.tech server permits requests from www.rainbowrichescasino.com.
Implement a CDN:
Action: While server performance is excellent, deploying a CDN (e.g., Cloudflare) would further improve load times for a global audience by caching static assets closer to users and provide benefits like DDoS mitigation.
Add Structured Data:
Action: Implement Organization and WebSite schema.org markup. This can be managed via the existing tag management solutions (Google Tag Manager, Tealium) to provide valuable context to search engines.
Lead Author's Summary and Final Rating
Momchil ChonovGambling Expert & Content Team Lead
Very HighOverall Expert Score7.0/10 or 70 %
After thoroughly testing Rainbow Riches Casino and reviewing the feedback from our expert team, I believe the operator really stands out for slot variety, frequent new releases, and a strong responsible gambling framework. The site’s commitment to user security is clear, with GDPR protocols, medium-level fund protection, and comprehensive support all laid out with clarity.
I especially appreciated the signature Rainbow Riches slot theme running throughout and the daily prize-chance games, which ensure the experience stays fresh. The live dealer game variety, on the other hand, can be improved, as the lobby is a bit limited. Adding specific filtering options for all games could also boost the appeal and make the whole website more user-friendly.
Technical performance is top-tier, with ultra-fast load times and a smooth mobile interface. Whether you’re after playful slot features, steady classics, or clear dispute and complaint processes, Rainbow Riches puts user value and peace of mind at its core.
