How We Rate Casinos
At Rosari, we've developed a comprehensive methodology to evaluate online casinos not on GamStop. Our ratings are designed to help UK players make informed decisions when choosing where to play. Each casino is assessed across eight key criteria, weighted by importance to player safety and experience.
1. Licensing & Regulation
This is our most critical assessment factor. We verify that casinos hold valid licenses from reputable gaming authorities. We specifically look for:
- MGA (Malta Gaming Authority) – One of Europe's most respected regulators
- UKGC (UK Gambling Commission) – The primary UK regulator
- Curaçao eGaming – A widely recognised offshore regulator
- Other legitimate local licenses from established jurisdictions
Unlicensed operators are heavily penalised in our ratings, as they offer no player protection or recourse.
2. Game Selection & Software Providers
We evaluate the variety and quality of games available, including:
- Slot machine variety and exclusivity
- Live casino offerings (blackjack, roulette, baccarat, game shows)
- Table games (poker, craps, and other variants)
- Partnerships with leading software providers (NetEnt, Pragmatic Play, Evolution Gaming, Microgaming, etc.)
- Regular game updates and new releases
Casinos with diverse, high-quality game libraries from established providers score higher.
3. Bonus Terms & Wagering Requirements
We thoroughly review bonus offerings and their conditions:
- Transparency of terms and conditions
- Wagering requirements (multipliers and fairness)
- Maximum cashout limits on bonuses
- Game restrictions (which games contribute to rollover)
- Time limits for bonus completion
- Overall value compared to the industry standard
Fair, transparent bonus terms with reasonable wagering requirements receive higher ratings. Hidden conditions or excessive requirements are flagged accordingly.
4. Payment Methods & Withdrawal Speed
We assess the convenience and reliability of financial transactions:
- Range of deposit methods (credit/debit cards, e-wallets, bank transfers, cryptocurrency)
- Cryptocurrency payment options (Bitcoin, Ethereum, etc.)
- Average withdrawal processing times
- Minimum and maximum deposit/withdrawal limits
- Transaction fees and hidden charges
- Security of payment processing
Fast, reliable withdrawals with multiple payment options rank higher in our ratings.
5. Customer Support
We evaluate the quality and availability of player assistance:
- 24/7 live chat availability
- Email support responsiveness (we test response times)
- Phone support where available
- Knowledge and helpfulness of support staff
- Support availability in English
- Help centre and FAQ comprehensiveness
Casinos offering round-the-clock support with quick, knowledgeable responses score higher.
6. Mobile Experience
We test the mobile functionality of each casino:
- Responsive design compatibility across devices
- Dedicated mobile apps (iOS and Android)
- Speed and performance on mobile
- Game availability on mobile platforms
- User interface and navigation ease
- Account management on mobile
Seamless, optimised mobile experiences are essential for modern casino players and reflect positively in our ratings.
7. Responsible Gaming Tools
We assess the commitment to player protection:
- Deposit limits (daily, weekly, monthly options)
- Loss limits and spending controls
- Self-exclusion features and ease of implementation
- Cooling-off periods
- Reality check reminders
- Links to gambling support organisations (Gamblers Anonymous, Gamblers Trust, etc.)
- Age verification and KYC compliance
Comprehensive, easily accessible responsible gaming tools demonstrate a casino's commitment to player welfare and significantly influence our ratings.
8. Our Rating Scale
Each casino receives a rating from 1 to 10, calculated from our weighted criteria:
- 9-10 (Excellent) – Top-tier casino with strong licensing, excellent games, fair bonuses, reliable support, and robust responsible gaming features
- 7-8 (Very Good) – Strong operator with solid credentials, good game selection, and reliable service
- 5-6 (Good) – Decent casino meeting basic standards but with room for improvement in one or more areas
- 3-4 (Fair) – Below-average experience with notable concerns in licensing, terms, or player protection
- 1-2 (Poor) – Significant issues including unverified licensing, unfair terms, or poor player protection
Note: We only review casinos that operate outside the UK's national self-exclusion scheme (GamStop). While these casinos may hold legitimate licenses from reputable authorities, players should carefully consider the additional risks of using non-GamStop operators and ensure they gamble responsibly.
