At Best Casinos Not on Gamstop Uk, our goal is to help players find safe and reliable online casinos. With hundreds of sites operating in the UK and beyond, it can be hard to tell which ones truly deliver a great experience and which ones fall flat.
That’s why we’ve built a careful, transparent review process that covers every critical aspect that makes for a safe online casino site.
Each casino featured in our articles is tested, rated, and compared using the same set of clear, consistent standards. Here’s how we do it.
1. Licensing & Regulation
The first and most important factor we check is licensing. Why? Because licensed casinos must follow strict rules on player protection, fairness, and financial transparency, making them, (in our opinion) the only safe online gambling option.
We verify that a site’s licence is valid and up to date by checking the licensing authority’s official register. If a casino fails to provide proper licensing details, it will not be included on our list. All of our recommended casino sites are regulated by recognised authorities, such as the UK Gambling Commission (UKGC), the Malta Gaming Authority (MGA), or the Curacao Gaming Control Board (GCB).
2. Security & Player Safety
Next, we examine how each site protects its users’ personal and financial information. The best casinos utilise SSL encryption, secure payment gateways, two-factor authentication, firewalls, and identity verification to prevent fraud. We also look at the platform’s data handling policies. We want to know how information is stored, who can access it, and whether the site complies with GDPR standards.
3. Game Selection & Software Quality
A strong casino should offer a balanced collection of games from trusted developers. Platforms in partnership with impressive providers such as Pragmatic Play, NetEnt, Evolution, and Play’n GO are more likely to earn our approval and respect. As are any sites that regularly audit their games for fairness.
We believe that all good casino sites should offer:
- Slot games with visible Return to Player rates.
- Virtual RNG versions of classic casino games like blackjack, roulette, and baccarat.
- Live dealer options for immersive inter-personal play.
- Speciality games like bingo, crash games, or lotteries.
4. Bonuses & Promotions
All too often, casino bonuses look fantastic at first glance, but fall to pieces in the fine print. That’s why we carefully examine every platform’s promotion terms. In particular, we look for any conditions that could undermine an otherwise excellent offer, such as:
- Wagering requirements.
- Minimum deposits.
- Game contribution rates.
- Withdrawal limits.
A fair bonus is one that’s achievable, transparent, and player-friendly. Only casinos that offer clear, honest promotions can earn our approval.
5. Deposit & Withdrawal Options
Fast and reliable payments are absolutely essential for a good gaming experience. That’s why we never forget to look into:
- Which deposit methods are supported.
- Minimum and maximum transaction limits.
- Withdrawal processing times.
- Any additional fees.
Casinos that support instant or same-day withdrawals get top marks from us. We also appreciate any platforms that verify player accounts quickly, as this helps to avoid payment delays later down the line.
6. Mobile Compatibility & User Experience
A modern casino must perform smoothly across all devices. We test every platform on both desktop and mobile, looking for:
- Fast load times.
- Simple navigation.
- Clear game layouts.
- Stable connections during gameplay.
We also test mobile browsers and apps, ensuring they deliver the same quality, functionality, and security as the main site.
7. Customer Support & Transparency
Good casinos don’t disappear when you need help. We contact customer support ourselves to test response times, professionalism, and clarity. Live chat, email, and help sections are all evaluated.
We expect:
- Friendly, responsive agents.
- 24/7 availability or extended hours.
- Informative FAQ sections answering the common questions players ask.
We also check whether the casino clearly displays its ownership details, contact information, and responsible gambling affiliations. Transparency is a major trust signal.
8. Online Reputation & Player Feedback
Finally, we take the wider player community into account. We review feedback from real players found on forums, social media, and other independent review sites. If a casino has a pattern of unresolved complaints, slow payouts, or misleading bonuses, it will not be recommended, no matter how attractive and polished it may appear.
How Ratings Are Scored
Each casino receives a score out of 10 based on each of these categories. The scores are averaged to create the final rating you see on our site. We update ratings regularly to reflect any major changes, such as new bonuses, improved features, or regulatory updates.
This process ensures that our reviews remain accurate and up-to-date, giving you the confidence to make informed choices before signing up.
