At CasinoUS, we want U.S. players to understand why an online casino earns its rating, not just which sites appear at the top of our rankings. Our team evaluates casinos across seven key areas, including licensing and security, games and software, bonuses, banking, customer support, mobile performance, and U.S. player suitability.
We look beyond headline bonuses and large game libraries. Our reviews consider the terms behind each offer, the available payment methods, withdrawal conditions, game providers, support options, responsible gambling features, and the overall experience for American players.
This guide explains how we rate online casinos, what we look for in each category, how the weighting system works, and why some casinos may fail our standards.

Key Insights
- CasinoUS rates casinos across seven weighted categories, rather than judging them by bonuses or game count alone.
- Security and licensing carry the greatest weighting at 25%, making them the most important part of the overall score.
- Games, bonuses and banking each account for 15%, giving these areas significant influence over the final rating.
- Bonus value depends on the terms. Wagering requirements, game contribution, expiry dates and cashout restrictions can significantly change the real value of an offer.
- Banking is assessed beyond deposits. Withdrawal methods, processing times, limits and KYC requirements are all considered.
- Mobile performance accounts for 10% of the rating, covering browser play, navigation, games and banking.
- U.S. suitability has its own 5% category, including USD support, state restrictions and U.S.-specific terms.
- A high rating does not guarantee a particular outcome. Casino games involve risk, and players should check current terms and local laws before playing.
- Ratings can change. Material changes to licensing, bonuses, banking, games or player restrictions can affect a casino’s assessment.
Our Promise: How We Review Casinos
A casino review should give you more than a list of promotional features. It should help you understand the potential strengths, weaknesses, restrictions, and trade-offs of the site.
Independent Evaluation
Our ratings are based on the criteria explained on this page. Affiliate relationships do not determine whether a casino receives a positive or negative rating.
Focused on U.S. Players
We consider factors that matter specifically to American players, including USD support, payment availability, player restrictions, state-level considerations, and relevant terms.
Clear Rating Criteria
Every casino is assessed across the same seven categories. This gives us a consistent framework for comparing different operators.
Regular Updates
Casino offers, payment methods, game libraries, licensing information, and terms can change. We update casino reviews when important information changes so that our ratings remain relevant.
Who Tests These Casinos, and How
CasinoUS reviews are built around hands-on testing and independent research rather than casino marketing claims. The current CasinoUS review methodology states that its experts sign up, make real-money deposits, test casino features and request withdrawals, while also considering player feedback and other research.
Our review process includes:
- Checking the operator and available licensing information
- Reviewing game providers and game categories
- Testing casino games where appropriate
- Examining welcome bonuses and promotional terms
- Testing available deposit and withdrawal methods
- Contacting customer support
- Checking responsible gambling features
- Testing the mobile experience
- Reviewing how well the casino caters to U.S. players
A casino does not receive a strong rating simply because it has a large bonus or thousands of games. The weighting system gives greater importance to security, licensing and other factors that can affect your money and account.
How We Rate Online Casinos in the USA
Our rating system uses seven core categories, each with a different weighting. The weighting reflects how important each area is to the overall casino experience.
| Category | Weighting | What We Check |
| Security & Licensing | 25% | Licensing, operator information, game testing, SSL and security |
| Games & Software | 15% | Game variety, providers, live casino, jackpots and performance |
| Bonuses & Promotions | 15% | Welcome offers, wagering requirements, restrictions and ongoing promotions |
| Banking & Payouts | 15% | Deposits, withdrawals, processing times, limits, fees and payment methods |
| Customer Support & Player Safety | 15% | Support quality, privacy and responsible gambling tools |
| Mobile Experience | 10% | Mobile browser performance, games, banking and apps |
| U.S. Player Focus | 5% | USD support, availability, restrictions and U.S.-specific terms |
This approach prevents one attractive feature, such as a large welcome bonus, from dominating the overall rating.
1. Online Casino Security and Licensing (25%)
Security is the first part of our review because players need to know who operates a casino and which regulator, if any, oversees it.
We examine:
- Licence status: We look for a licence that can be verified through the relevant regulator.
- Operator information: We check who owns and operates the casino and whether the information is clearly disclosed.
- Game testing: Where claimed, we look for independent testing from recognised laboratories such as eCOGRA, iTech Labs or GLI.
- Website security: We check for HTTPS and valid encryption protecting information sent between your device and the casino.
- Player terms: We review the casino’s terms for important restrictions affecting accounts, bonuses and withdrawals.
A licence badge on its own is not enough. The licence information should be consistent with the relevant regulatory records.
2. Online Casino Games and Software (15%)
Game count is only part of the assessment. We look at who supplies the games, how much genuine variety is available and how well the casino performs.
Our checks include:
- Slots and video slots
- Blackjack
- Roulette
- Baccarat
- Poker and video poker
- Live dealer games
- Progressive jackpots
- Free-play games where available
- Software providers
- Browser performance
- Downloadable software where offered
We also look at provider quality. A casino advertising thousands of games may have a weaker library if much of the catalogue comes from a small number of providers or contains repeated versions of similar titles.
3. Online Casino Bonuses and Promotions (15%)
The biggest bonus is not automatically the best casino bonus. We assess what you actually need to do before bonus funds or winnings can be withdrawn.
We review:
- Welcome bonus percentage and maximum value
- Minimum deposit
- Wagering requirement
- Maximum bet while a bonus is active
- Game contribution rates
- Maximum cashout restrictions
- Bonus expiry
- Eligible payment methods
- Reload bonuses
- Cashback
- Free spins
- VIP and loyalty rewards
For example, a 35x wagering requirement on a $200 bonus means $7,000 in qualifying wagers. If blackjack contributes only 10% towards the requirement, the practical cost of clearing the bonus can be much higher than the headline figure suggests.
We therefore judge bonuses by their terms, not their advertised value alone.
4. Online Casino Payments, Deposits and Payouts (15%)
Banking is one of the areas we examine most closely because the player experience does not end when a withdrawal is requested.
We assess:
- Deposit methods
- Withdrawal methods
- Minimum and maximum transaction limits
- Processing times
- Pending withdrawal periods
- Payment fees
- USD support
- Cryptocurrency availability where offered
- KYC and verification requirements
We separate casino processing time from payment delivery time. A casino may approve a withdrawal within hours while the chosen payment provider takes longer to deliver the funds.
We also look for restrictions that may not be obvious from the cashier, such as a payment method being unavailable for withdrawals or a bonus preventing a particular withdrawal route.
5. Online Casino Customer Support and Player Safety (15%)
Good customer support needs to do more than provide a live chat button. We assess whether players can reach a real person and whether the response actually resolves the issue.
We check:
- Live chat
- Email support
- Telephone support where offered
- FAQ and help sections
- Response times
- Accuracy of answers
- Responsible gambling tools
- Self-exclusion
- Deposit limits
- Session or time limits
- Privacy policies
We also consider how the casino handles account and payment questions. A fast response that does not answer the question is less useful than a clear response that resolves the problem.
6. Mobile Casino Experience (10%)
Mobile performance is part of the core casino experience. We test casino websites on mobile devices to see whether important features continue to work properly.
Our checks include:
- Page loading
- Navigation
- Game availability
- Account management
- Deposits and withdrawals
- Game performance
- Screen responsiveness
- iOS and Android compatibility
- Dedicated apps where available
A casino does not need a dedicated app to score well. A well-built mobile browser experience can be just as useful if it provides the required games, banking tools and account features.
7. U.S. Player Focus (5%)
The final category looks specifically at how well an offshore casino serves American players.
We check:
- USD support
- U.S. player acceptance
- Relevant legal disclosures
- Payment methods available to U.S. players
- Customer support accessibility
- Any state or regional restrictions
- Terms that specifically affect American players
This category carries 5% because it is primarily a suitability check. A casino may perform well across the other categories but still be unsuitable if it does not accept players from your location.
How Our Casino Rating System Works
Each category contributes a specific percentage to the overall score.
For example, Security & Licensing contributes up to 25 points, while Mobile Experience contributes up to 10 points.
This weighting ensures that fundamental factors such as security, licensing and banking have more influence than secondary features.
A casino does not need to have the largest game library or the biggest bonus to receive a strong overall rating. Consistent performance across the most important categories is more valuable.
What RTP Means in Our Casino Reviews
RTP stands for Return to Player. It represents the theoretical percentage a game is designed to return to players over a very large number of rounds.
A game with 96% RTP has a theoretical return of $96 for every $100 wagered over a long period. It does not mean you receive $96 back after wagering $100 in one session.
RTP also does not remove short-term variance. A player can win or lose significantly more than the theoretical percentage during an individual session.
We check whether RTP information is available and, where appropriate, compare published figures against available third-party information.
How We Compare Casinos Using Our Criteria
The weighting system gives us a consistent way to compare different casino operators. A casino does not need to be the best at everything to rank highly, but serious weaknesses in high-weight categories can have a large effect on the final result.
Example: Why a Strong Casino Can Rank Highly
A casino with verified licensing, independently tested games, reliable banking, clear bonus terms and responsive support can perform well even if it does not have the biggest bonus on the market.
The reasoning is simple: the bonus is only one part of the player experience.
Example: Why a Large Bonus Can Still Score Poorly
A casino advertising a large welcome package can lose points if the offer has a high wagering requirement, restrictive game weighting, a maximum cashout or a short expiry period.
The headline value is therefore never assessed in isolation.
When a Casino Fails Our Standards
A casino can be removed from consideration when serious issues affect player safety, fairness or access to funds.
Common reasons for failing our standards include:
- No verifiable licence information
- A licence claim that cannot be confirmed
- Missing or unverifiable game testing claims
- Evidence of unexplained withdrawal delays
- Unclear or misleading bonus terms
- Excessive withdrawal restrictions
- Poor customer support
- Missing player protection tools
- Serious privacy concerns
- Restrictions that make the casino unsuitable for U.S. players
Player complaints can also trigger a further investigation. A complaint alone does not automatically make a casino unsuitable, but repeated and documented issues can lead to a rating change.
How Often We Retest and Update Our Ratings
Casino terms, payment methods and promotional offers can change. Licensing information can also change, so ratings need to be reviewed rather than treated as permanent.
CasinoUS states that its casino information is regularly updated and fact-checked as offers, terms and regulations change.
We update individual reviews when material information changes, including:
- Bonus terms
- Payment methods
- Withdrawal conditions
- Licensing information
- Game availability
- Support options
- Responsible gambling tools
How Player Feedback Influences Our Ratings
Hands-on testing provides one part of the picture. Player feedback can highlight issues that may not appear during a single test transaction.
We consider relevant complaints, forum discussions and other player feedback alongside our own research. The current CasinoUS review methodology also states that player feedback and external reviews are considered when assessing casinos.
Feedback is treated as evidence to investigate rather than automatic proof of wrongdoing. We look for patterns and try to distinguish isolated complaints from repeated issues.
How to Use CasinoUS Ratings When Choosing a Casino
A rating gives you a quick comparison, but it should not replace checking the details that matter most to you.
If you care about withdrawals, pay close attention to processing times, pending periods and available payment methods. If bonuses are your priority, compare wagering requirements, game weighting and maximum cashout rules rather than headline values.
You should also confirm that the casino accepts players from your state and that online casino gambling is permitted under the laws that apply to you.
Final Verdict
CasinoUS ratings are designed to make comparing online casinos easier without reducing the decision to a single bonus or promotional figure. Our methodology considers the factors that can have the biggest impact on the overall player experience.
When comparing an online casino, we recommend prioritising:
- Security and licensing: Check who regulates the casino and whether its licence information can be independently verified.
- Games and software: Look beyond the advertised game count and check the providers, game variety and overall library quality.
- Bonuses and promotions: Compare wagering requirements, game contribution, expiry dates, maximum bets and cashout restrictions.
- Banking and payouts: Review the complete withdrawal process, including processing times, limits, fees and verification requirements.
- Customer support: Check whether support is accessible, responsive and able to provide clear answers when problems arise.
- Mobile experience: Make sure the games, cashier and account features work properly on your smartphone or tablet.
- U.S. player suitability: Confirm USD support, state availability and any restrictions or terms that apply to players in your location.
The highest-rated casinos are generally those that perform consistently across these areas rather than simply offering the biggest bonus or largest game library.
No rating can remove the risks associated with online gambling. The purpose of the CasinoUS methodology is to make differences, restrictions and potential risks easier to understand before you decide whether to register or deposit. Always check the latest terms and applicable laws in your state before playing.
Responsible Gambling
CasinoUS believes online casino play should be treated as entertainment, not a way to make money. Gambling can involve financial risk, so it is important to stay in control and only play with money you can afford to lose.
If gambling is becoming difficult to manage, consider:
- Setting a personal budget before you play and sticking to it.
- Setting time limits to prevent extended playing sessions.
- Taking a break if gambling starts to feel difficult to control.
- Using responsible gambling tools such as deposit limits, time-outs or self-exclusion where available.
- Seeking professional support if gambling is negatively affecting your finances, relationships, work or wellbeing.
Important: CasinoUS content is intended for adults aged 21 and over. Online casino availability and gambling laws vary by U.S. state. Check your local laws and requirements before playing.
How We Rate Online Casinos FAQs
How Does CasinoUS Rate Online Casinos?
CasinoUS evaluates online casinos across seven categories: security and licensing, games and software, bonuses and promotions, banking and payouts, customer support and player safety, mobile experience, and U.S. player focus.
What Is the Most Important Part of a Casino Rating?
Security and licensing have the highest weighting at 25%. We consider licence information, operator transparency, game testing, website security and other factors that can affect player safety.
How Do You Check if an Online Casino Is Licensed?
We review the licence information provided by the casino and, where possible, verify it against relevant regulatory or licensing records. A licence logo alone is not treated as sufficient evidence.
How Do You Rate Casino Bonuses?
We look beyond the advertised bonus amount. Our assessment includes wagering requirements, maximum bets, game contribution, expiry periods, maximum cashouts and other terms that affect how usable the promotion is.
What Does 96% RTP Mean?
A 96% RTP means a game has a theoretical long-term return of 96% of wagers. It does not mean that a player will receive 96% of their money back during an individual session.
How Do You Rate Casino Withdrawals?
We examine withdrawal methods, processing times, limits, fees, pending periods and KYC requirements. We also distinguish between the casino’s processing time and the time required by the payment provider.
Do You Consider U.S. State Restrictions?
Yes. U.S. player suitability is one of our rating categories. We consider whether a casino accepts players from particular states and whether specific restrictions apply.
Does a Casino Need a Mobile App to Receive a High Rating?
No. A dedicated app is not required. A responsive mobile website can score well if it provides reliable gameplay, account management and banking features.
Can a Casino With a Smaller Bonus Receive a Higher Rating?
Yes. Bonuses account for only 15% of the overall rating. A casino with a smaller bonus can rank higher if it performs better across security, banking, games, support and other categories.
How Often Are Casino Ratings Updated?
Ratings are updated when important information changes. This can include bonuses, banking conditions, licensing, game availability, support options or restrictions affecting U.S. players.
