A rating is only useful if you know how it was reached. This page explains exactly how SureOnlineCasino scores online casinos and sportsbooks: what we check, how much each factor counts, and what automatically rules an operator out.
Our system is built around one principle: safety comes first. A casino with thousands of games or a huge welcome bonus is no use to you if your money, your data or your winnings aren’t protected. That’s why licensing and security carry the most weight in every rating we publish.
Before We Score: The Licensing Check
Every review starts with a simple question: is this operator licensed by a US state regulator?
We confirm each operator’s license directly on the regulator’s own website, such as the New Jersey Division of Gaming Enforcement, the Pennsylvania Gaming Control Board or the Michigan Gaming Control Board, and note exactly which states it is approved in.
If an operator isn’t licensed in at least one US state, we don’t score it at all. We won’t review, rate or recommend offshore casinos, unlicensed sportsbooks or sites that accept US players without state approval.
Our Rating System at a Glance
Once an operator passes the licensing check, we score it across six weighted categories covering eight criteria. The weighting reflects how much each factor affects your safety and experience as a player.
| Category | What We Assess | Weighting |
|---|---|---|
| Licensing, Safety & Security | State license, data protection, fair games, reputation | 25% |
| Payouts & Withdrawal Speed | Payment methods, payout times, fees, limits | 20% |
| Bonus Value & Wagering Requirements | Bonus terms, wagering, promotions, loyalty | 15% |
| Games, Odds & Betting Markets | Game library, RTP, sports markets, odds | 15% |
| Responsible Gambling Tools | Limits, reality checks, self-exclusion, support | 15% |
| Mobile Experience & Customer Support | Apps, usability, support channels, response times | 10% |
How We Assess Each Category
Licensing, Safety and Security (25%)
This is the foundation of every rating. Beyond confirming a valid state license, we look at:
- The number of states the operator is licensed in, and its compliance record with regulators
- Data protection, including encryption and secure login options such as two-factor authentication
- Game fairness, including independent testing of games and random number generators
- Account verification and geolocation checks, which regulated operators must use
- The operator’s reputation, ownership and history of player complaints
An operator that scores poorly here won’t be recommended, however well it performs elsewhere.
Payouts and Withdrawal Speed (20%)
Getting paid should be simple. We assess how easily you can move money in and out, including:
- The range of deposit and withdrawal methods, such as debit cards, PayPal, Play+ and online banking
- Realistic withdrawal processing times, not just advertised ones
- Fees, minimums and maximum withdrawal limits
- How clear the verification process is before your first withdrawal
- Whether withdrawal terms are easy to find and understand
Operators that delay payouts without explanation, or make withdrawals unnecessarily difficult, lose significant points.
Bonus Value and Wagering Requirements (15%)
A big headline bonus can hide terms that make it almost impossible to benefit from. We look past the offer size and assess:
- Wagering requirements, and how realistic they are to complete
- Time limits, maximum bet rules and game restrictions
- Whether bonus terms are clearly displayed before you opt in
- The value of ongoing promotions and loyalty programs for existing players
- Whether promotions are presented responsibly, without pressure tactics
A smaller bonus with fair terms often scores higher than a large bonus with restrictive ones.
Games, Odds and Betting Markets (15%)
This category looks at the quality of what you can actually play or bet on.
For online casinos, we assess:
- The size and variety of the game library, including slots, table games and live dealer games
- Games from established, regulated suppliers
- Published return-to-player (RTP) rates and how easy they are to find
- Jackpot options and the range of stakes available
For sportsbooks, we assess:
- The range of sports, leagues and bet types
- How competitive the odds are on popular markets
- Live betting, same-game parlays and cash-out options
- How quickly odds and markets update during live events
Responsible Gambling Tools (15%)
Many review sites don’t score responsible gambling at all. We give it the same weight as bonuses and games, because the tools an operator offers say a lot about how it treats its players. We check for:
- Deposit, wager and time limits that are easy to set
- Reality checks and activity statements
- Cool-off periods and self-exclusion options
- Links to support services such as 1-800-GAMBLER
- Whether the operator avoids aggressive marketing and pressure to deposit
Mobile Experience and Customer Support (10%)
Most players now bet on their phones, and everyone needs help at some point. We assess:
- App quality and stability on iOS and Android, and the mobile browser experience
- Navigation, load times and ease of finding key features
- Customer support channels, such as live chat, email and phone
- Response times and whether support staff can actually resolve problems
- Help center quality, including clear answers to common questions
Automatic Disqualifiers
Some issues rule out a recommendation immediately, regardless of score:
- No valid US state gaming license
- Evidence of unfair or untested games
- Repeated, unresolved withdrawal complaints
- Misleading bonus terms or hidden restrictions
- No responsible gambling tools, such as limits or self-exclusion
- Serious regulatory action, such as license suspension
If an operator we’ve already reviewed develops any of these issues, we remove our recommendation and update the review.
How We Test
Our reviews combine research with hands-on testing. For each operator, we:
- Open an account and complete the verification process
- Make deposits and request withdrawals to record real processing times
- Play games or place bets across desktop and mobile
- Contact customer support with real questions
- Read the full terms and conditions, bonus rules and responsible gambling policies
- Check licensing and regulatory records with the relevant state regulators
Our Rating Scale
Each category is scored out of 10, then weighted to produce a final score out of 10:
- 9.0–10: Excellent. Among the best licensed operators available.
- 8.0–8.9: Very good. A strong choice with only minor drawbacks.
- 7.0–7.9: Good. A solid operator with some clear weaknesses.
- 6.0–6.9: Fair. Usable, but better alternatives are available.
- Below 6.0: Not recommended.
Example: How a Final Score Is Calculated
Here’s how an example operator’s score comes together:
- Licensing, Safety and Security: 9.5 × 25% = 2.38
- Payouts and Withdrawal Speed: 8.5 × 20% = 1.70
- Bonus Value and Wagering Requirements: 7.0 × 15% = 1.05
- Games, Odds and Betting Markets: 9.0 × 15% = 1.35
- Responsible Gambling Tools: 8.5 × 15% = 1.28
- Mobile Experience and Customer Support: 8.0 × 10% = 0.80
Final score: 8.6 out of 10 (Very good)
How We Rate Sports Predictions
Our sports predictions aren’t scored like operator reviews, but they follow their own standards. Every pick includes the reasoning behind it, based on team form, injuries, head-to-head records and odds value. We never describe a pick as guaranteed, and we track and publish our results, including losses.
Keeping Ratings Up to Date
Operators change their bonuses, payment options and terms regularly, and state laws change too. We recheck our reviews on a regular schedule, and update ratings immediately when:
- An operator’s license status changes
- Bonus terms or payment methods change significantly
- We see a pattern of player complaints
- New features, apps or state launches affect the experience
Every review shows the date it was last updated.
Our Independence
SureOnlineCasino may earn a commission when readers sign up with some operators we feature. This never affects our scores. Operators can’t pay for a higher rating, a better position in our rankings or a more favorable review, and we publish the drawbacks of every operator, including those we have commercial relationships with.
