How We Review Non GamStop Casinos

Full transparency about our testing methodology, 10-point scoring system and the steps we take to ensure every review is accurate, fair and genuinely useful.

Our Testing Philosophy

At Tabbar House, we believe that credible casino reviews must be based on real experience, not press releases, marketing materials or secondhand information. Every casino featured on our site has been personally tested by our team using real money, real accounts and a standardised testing process that takes a minimum of 5 days per casino.

We understand that our readers are making financial decisions based on our recommendations. That responsibility drives everything we do — from our rigorous testing methodology to our quarterly re-testing schedule and our commitment to removing casinos that fail to maintain standards.

Below, we explain every aspect of our review process in full detail. If you have questions about any part of our methodology, please contact us.

Our 10-Point Scoring System Explained

Every casino is evaluated against eight weighted categories. Each category is scored on a scale of 1 to 10, and the weighted average produces the casino’s overall rating (displayed as X/5 on our site for simplicity). Here is a detailed breakdown of each category and what we assess.

20%

1. Safety & Licensing

The most heavily weighted category because player safety is paramount. We verify the casino’s licence directly with the issuing regulator, check SSL encryption, confirm RNG certification from independent laboratories (eCOGRA, iTech Labs, GLI), review data protection policies and research the operator’s history for any regulatory actions, fines or player complaints. A casino with an unverifiable licence automatically fails our review.

15%

2. Game Selection

We assess the total number of games, the diversity of game categories (slots, live dealer, table games, crash games, scratch cards), the quality and reputation of software providers, the availability of popular UK-market titles, and whether exclusive or unique games are offered. We also check for games from restricted providers that should not be accessible in certain jurisdictions.

15%

3. Bonus Value

Bonuses are evaluated on their genuine value to players, not headline figures. We analyse the welcome bonus amount, wagering requirements, maximum cashout limits, game contribution rates, expiry periods, minimum deposit thresholds and the quality of ongoing promotions (cashback, reload bonuses, VIP programmes). A large bonus with a 60x wagering requirement scores lower than a modest bonus with 25x.

15%

4. Payout Speed & Reliability

We process at least one real withdrawal at every casino and time the process from request to funds received. We test multiple payment methods where possible. Payout reliability is equally important — we check for patterns of delayed or refused withdrawals in player forums and complaint databases. Casinos with verified payout issues are demoted or removed.

10%

5. Payment Options

We evaluate the range of available deposit and withdrawal methods, GBP currency support, cryptocurrency availability, fee transparency, minimum deposit/withdrawal thresholds and the consistency of payment processing. Special attention is given to methods that avoid UK bank blocking issues.

10%

6. User Experience

Our team assesses website design and layout, mobile responsiveness (tested on iPhone, Samsung and iPad), navigation quality, page load speed, the registration process (simplicity and time required), game search and filtering functionality, and overall aesthetic quality.

10%

7. Customer Support

We contact every casino’s customer support at least three times during our testing — once via live chat, once via email and once with a deliberately complex query. We measure response times, assess the quality and accuracy of answers, check language capabilities and evaluate the helpfulness and professionalism of support agents.

5%

8. Responsible Gambling Tools

We check for the availability of deposit limits, loss limits, session timers, cooling-off periods, voluntary self-exclusion, reality checks and links to external support organisations. Casinos that offer comprehensive responsible gambling tools score higher. Those with no tools at all receive a significant penalty.

Testing Process: Step by Step

Our review process follows a consistent, standardised procedure for every casino. Here is exactly what happens from start to finish.

Step 1: Preliminary Research (Day 1)

Before creating an account, we conduct thorough background research. This includes verifying the casino’s licence on the regulator’s official website, checking SSL certificate validity, researching the operating company, reviewing player feedback on forums (AskGamblers, CasinoGuru, Reddit) and checking complaint databases for unresolved issues. If a casino fails these preliminary checks, we do not proceed further.

Step 2: Registration & Verification (Day 1)

We create a real account using genuine details, timing the registration process and noting any issues. We assess the KYC (Know Your Customer) verification process, including what documents are required, how long verification takes and whether the process is clearly explained.

Step 3: Deposit Testing (Day 1–2)

We make real deposits using multiple payment methods (typically crypto, e-wallet and debit card) in GBP. We record deposit speed, any fees charged, minimum deposit amounts and the overall deposit experience. If the casino offers a welcome bonus, we opt in and document all terms and conditions.

Step 4: Game Testing (Day 2–4)

Our games specialist plays a minimum of 50 sessions across different game categories: slots (at least 20 titles from different providers), live dealer games (at least 5 tables), table games (at least 5 variants) and any speciality games (crash games, bonus-buy slots). We assess game loading times, mobile performance, graphical quality and whether advertised RTP values are accurate.

Step 5: Customer Support Testing (Day 3–4)

We contact customer support via live chat (timing the response), email (timing the reply) and with a deliberately complex query about bonus terms or withdrawal procedures. We assess response quality, accuracy, helpfulness and professionalism.

Step 6: Withdrawal Testing (Day 4–5)

We request a real withdrawal and time the entire process from request to funds received. We note any additional verification requirements, processing delays or unexpected issues. If a withdrawal takes significantly longer than advertised, we follow up with customer support and document the interaction.

Step 7: Scoring & Review Writing (Day 5)

Using the data collected across all testing phases, each team member scores their respective category. Scores are combined using our weighted formula to produce the overall rating. The review is written, fact-checked by a second team member and published.

✅ Real Money, Real Testing

We spend a minimum of £200 at every casino we review. This is not promotional credit or free play — it is real money from our operating budget. We believe this is the only way to provide reviews that genuinely reflect the player experience.

Quarterly Re-Testing Schedule

A casino review is only useful if it is current. The iGaming industry moves quickly — bonuses change, payment methods are added or removed, customer support quality can fluctuate and licensing status can change. That is why we re-test every casino on our site at least once per quarter.

What We Check During Re-Testing

  • Licence status: We re-verify the casino’s licence on the regulator’s website to confirm it remains active and valid.
  • Bonus terms: We check for changes to welcome bonuses, wagering requirements, maximum cashout limits and ongoing promotions.
  • Payout reliability: We process another real withdrawal and check player forums for any new payout complaints.
  • Game library changes: We note any significant additions or removals of game providers or titles.
  • Customer support quality: We contact support again to verify that response times and quality remain consistent.
  • Payment method availability: We confirm which payment methods are still available and check for any fee changes.
  • Responsible gambling tools: We verify that all previously available responsible gambling features are still functional.

Re-Testing Outcomes

Based on re-testing results, a casino’s rating may be:

  • Maintained: No significant changes detected; the rating stands.
  • Upgraded: The casino has improved in one or more categories, warranting a higher score.
  • Demoted: Quality has declined in one or more areas, resulting in a lower score and potentially a lower ranking.
  • Removed: Serious issues have been identified (e.g. licence revocation, widespread payout failures, security concerns) and the casino is removed from our recommendations entirely.

Our most recent full re-testing cycle was completed on 5th May 2026. The next scheduled re-test is August 2026.

How We Handle Conflicts of Interest

As an affiliate website, we earn commissions when readers register at casinos through our links. We recognise that this creates a potential conflict of interest, and we take several concrete steps to mitigate it.

Our Safeguards

  • Editorial independence: Our editorial team operates independently from commercial decisions. Reviewers do not know (and are not told) the commission rates of different casinos.
  • Performance-based rankings: Casino rankings are determined solely by our scoring methodology. A casino offering a 50% revenue share will not outrank one offering 30% if it performs worse in our testing.
  • Removal policy: We have removed casinos from our site that generated significant revenue when they failed re-testing. Our reputation is worth more than any single affiliate relationship.
  • No pay-for-play: Casinos cannot pay for reviews, higher rankings or more favourable coverage. We do not accept sponsored reviews or advertorial content.
  • Disclosure: All affiliate relationships are clearly disclosed in our Editorial Policy and in the footer of every page.

Transparency About Affiliate Relationships

We believe full transparency about our business model is essential for maintaining trust. Here is how our affiliate relationships work:

  • When you click a “Visit Casino” link on our site and register at the casino, we may receive a commission from the casino operator.
  • The commission is paid by the casino, not by you. There is no additional cost to you for using our links.
  • Commission rates vary between casinos and are based on revenue share or cost-per-acquisition models.
  • We review and recommend casinos based on quality, not commission rates. If a casino scores poorly in our testing, it will not appear on our site regardless of how much commission it offers.
  • We always aim to include both affiliate-linked and non-affiliate-linked information in our content, so you can make informed choices.
