How We Score Casinos, Betting Sites and Poker Rooms

At GameReactor, we put every gambling site we review through the same comprehensive process. From signing up to withdrawing funds, and everything in between, we use real-world testing to give you the lowdown on the best site in every relevant category. 

We assess every casino, sportsbook, and poker room using six key weighted factors, and give them a final score out of 10. The individual tests vary according to the product. Our team judges casinos on criteria like games and RTP, sports betting sites on odds and market depth, and poker rooms on traffic and rake. However, our scoring framework stays consistent, so it’s easier to compare competing sites. 

The Cheat Sheet: Our Scoring System at a Glance

Although each of the six categories is important, they’re not weighted equally. Games, software, and betting markets carry the most weight since they determine what you can play or bet on. Payments and safety are close behind because an impressive-looking product means little if withdrawals are unreliable, or the operator can’t meet our strict security and fair-play standards.

Next up come bonuses, with fair terms and genuine value mattering more than a gigantic promotional figure. Finally, we evaluate mobile experience and bettor support on things such as how well the site performs during everyday use, and how the operator reacts when something goes wrong.

Here’s an at-a-glance look at category weighting, and we’ll provide a detailed explanation a little later on.

Category	Weight
The Game Room — Games, Software & Betting Markets	25%
Payments & Withdrawals	20%
Safety, Security & Fair Play	20%
Bonuses & Rewards	15%
Mobile Experience	10%
Player Support	10%
Final Score	Score out of 10

The Playthrough: How We Test

We know that the only way to provide accurate reviews is through hands-on testing. Our team does everything you do, from registering and funding our accounts to withdrawing winnings.

Here’s a 5-step walkthrough of the process:

• Registration: We create an account and assess the sign-up process, including whether the platform requires immediate or pre-withdrawal account verification.

• Real Money Deposits: Our team analyses the available payment methods and tries to use at least two per site to gauge the minimum deposit, fees, and processing times.
  

• It’s Time to Play: From there, we get to the fun part and test the main product. This means trying slots, live dealer games, and speciality titles at casinos, placing bets on sportsbooks, and trying multiple hands in different poker rooms.

• We Contact Support: We pose a variety of practical questions to the site’s support team through live chat and email. Then we note the response time, accuracy, and usefulness of the answer.

• Request a Withdrawal: We cash out using multiple payment methods when available. Our team compares the site’s advertised timeframe with our experience, and records verification requests, fees, or avoidable delays.

When possible, we repeat important checks across desktop and mobile devices. Although we also perform general research into each brand, it doesn’t replace first-hand testing. If we find that an advertised feature, promo, or payment option doesn’t work as described, our score reflects the truth, not the marketing promises.

The Final Score: What Our Ratings Actually Mean

Our Final Score condenses the six weighted categories into a single rating out of 10. We don’t base it on a brand’s reputation or reach, nor on a single monster welcome offer. Instead, a platform must perform across the entire player experience to become one of our top-rated recommendations.

After scoring each individual category out of 10, we apply its weighting. For example, a score of 8/10 in The Game Room contributes two points to the final rating since that category is worth 25%. Likewise, a 10/10 total in Mobile Experience adds 1 point to the score, since that section is worth 10%.

As you can see, a platform can excel in two, three, or even four categories, but if it’s deficient in one, two, or three, its final score will suffer.

Here’s what each score represents.

Score	What It Means
9 – 10	Outstanding. A score of 9+ indicates that a site is an industry leader with superb performance across almost every category.
8 – 8.9	Excellent. A clear recommendation with strong core features and minor compromises.
7 – 7.9	Good. A solid, dependable option that performs well but has noticeable weaknesses or simply has better-performing rivals.
6 – 6.9	Mixed. The site is okay and might suit a particular type of player. However, it has major downsides that limit its overall appeal.
5.9 or Lower	Poor. These sites have a significant number of issues and are best avoided in their current forms.

We refuse to recommend any casino, sportsbook, or poker room if it fails our licensing, security, or fair-play checks, regardless of how it performs in other categories.

The Game Room — Games, Software and Betting Markets (25%)

Since the main product dictates your experience, this is the largest part of our scoring system. While a huge catalogue is helpful, we also assess quality, variety, value, and real-world performance.

Our exact tests depend on what the platform offers. For example, we judge casinos on their games and software, sportsbooks on their odds and market coverage, and poker rooms on their tables and traffic. When it comes to hybrid sites, we delve into every product they offer.

Casino Games and Software

We count the available games and have found online casinos with 10,000+ titles. Yet, this is only a surface-level insight, as our team is intent on finding out how each platform balances its library.

We expect to see bonus buy, jackpot, and Megaways slots, RNG table games, live dealer tables with variants of classics and game shows, and a healthy selection of speciality titles such as crash, mines, and Plinko.

Provider quality is another key component. In addition, we search, filter, and launch games to assess lobby performance. Issues such as broken filters, slow loading, unavailable titles, or awkward navigation are noted. Finally, we examine the range of low, medium, and high-volatility games and jackpot sizes. This lets us know whether the library supports different bankrolls, playing styles, and potential win ceilings.

Sports and Betting Markets

We check whether a sportsbook’s range actually holds up once you look past the marquee fixtures, since that depth affects how fast and cleanly a winning bet turns into a payout.

• Sport and league coverage: We expect sportsbooks to cover major sports, international leagues, and worthwhile niche competitions. We enter individual events to measure the real depth of the market.

• Market depth: Match winner, over/under totals, and handicap betting markets should be standard. Top-rated sites go further by offering significant volumes of player props, Asian handicaps, alternative lines, specials, and same-game accas. The best-scoring platforms provide great depth for English Premier League games, but also plenty of options on leagues like the Tajikistan Higher League and the Bhutan Premier League.

• Bet slip performance: We test the bet slip via singles and accas, checking how quickly selections appear, whether potential returns are clear, and how easy it is to add or remove a leg.

Poker Tables and Traffic

The best poker rooms combine variety with active opponents. We check for the number of tables with standard Texas Hold’em and Omaha, and variants such as 6+ Hold’em, 5-Card and 6-Card Omaha, and Omaha Hi-Lo. It’s also important for platforms to offer a practical range of micro, low, medium, and high-stakes options.

Our playthrough covers cash tables, sit-and-go tournaments, scheduled events, and fast-fold formats when available. We test both the desktop and mobile clients for table navigation, stability, reconnection, and feature parity. There’s no point in having a ‘polished’ poker client if the games seldom run properly!

That’s why we record real-money traffic during peak and off-peak periods, and check whether the site has large tournament fields, full cash game tables, and guaranteed prize pools. Poker rooms that enable us to find a game at any time, instead of waiting for specific periods, tend to score well.

RTP, Odds and Rake

No matter which game you play, there should be a realistic expectation of a fair payout. At casinos, we expect to see clearly displayed return-to-player (RTP) percentages and check whether sites offer the highest available RTP for a game if there are several configurations. We also look for the volume of slots with an RTP of 96% or higher, low house edge variants of classics, and tables with solid payouts, such as 3-to-2 blackjack.

When it comes to sportsbooks, we compare pricing across a variety of markets and calculate the bookmaker’s margin. We look at headline events, niche leagues, and in-play markets to ensure that betting sites offer competitive odds across-the-board, rather than focusing on a small number of areas.

As for poker rooms, we investigate the rake charged on cash pots, along with the built-in caps and fees on tournament buy-ins. Ultimately, sites with transparent, competitive structures score well, while platforms with high or hard-to-find charges are scored appropriately.

Live Dealer, In-Play and Real-Time Play

Once the action heats up, it’s essential that a platform provides a stable level of performance. At casinos, we test the variety of live dealer games, including blackjack, baccarat, and roulette tables, along with game shows. This process involves analysing stream quality, betting windows, table limits, and mobile performance.

When reviewing sportsbooks, we examine the number of in-play markets on offer, check how quickly odds update, and note how often a site suspends selections. We mark down any sportsbook with a tendency to prevent betting dozens of times per match. Our team also tests live stats, cash-out functions, and event streaming when it’s available.

For poker, our focus switches to table responsiveness, reliable reconnection and the speed of fast-fold formats. Platforms lose points if we regularly experience delays and freezes, leading to missed betting opportunities.

Tournaments and Leaderboards

Tournaments should always add real substance to your experience rather than being mere decoration.

At casinos, we examine tournament frequency, entry rules, leaderboard transparency, and whether it’s actually possible to win the advertised prizes. For instance, we aren’t impressed by slot events that require £25,000 worth of bets to win £100!

We assess sportsbooks on their betting competitions, predictor games, and event-based leaderboards. Our team checks how the site decides winners, what qualifies as an entry, and whether the promo rewards skill, activity, or those who spend the most.

As for poker rooms, we look at the multi-table tournament schedule, guaranteed prize pools, buy-in range, and format variety. Options such as regular freezeouts, rebuys, bounty events, satellites, and major series create more choice.

Payments and Withdrawals (20%)

This is the category where online gambling sites either lose or earn our trust. In our experience, deposits are almost always easy; the real test of a platform’s credentials comes when it’s time to cash out.

We make real-money deposits, play games, meet bonus wagering requirements if applicable, and request a withdrawal whenever full testing is possible. Our score reflects the complete journey and includes factors such as payment choice, processing speed, verification, limits, and fees.

Payment Methods

Our team checks the platform’s cashier to see if it accepts debit and credit cards, e-wallets, bank transfers, prepaid vouchers, and cryptocurrency.

Of course, a lengthy list of payment options isn’t a guarantee of anything. That’s why we perform real testing in the expectation of finding rapid deposits, correctly updated balances, and whether eligible payouts can return through the same route. We identify deposit-only methods, such as PaysafeCard, early, as they require you to arrange an alternative withdrawal method.

We also consider support for local currencies and region-specific banking methods. Sites typically fare better in our rankings when their cashiers provide practical options without forcing us into inconvenient payment routes or unnecessary conversions that cost money.

Cash Out Speed and Reliability

This is a critical consideration as it holds the key to your entire user experience. We make withdrawals and compare each site’s advertised processing time with the reality.

Our team performs several withdrawals using different payment options and looks for consistent processing, accurate status updates, unexpected delays, and additional checks. We also find out if there are methods that pay out in hours and whether we can lock a pending withdrawal to prevent it from being reversed.

Red flags include misleading timeframes as quoted by the site, repeated stalling when making withdrawals, or customer support that’s unable to explain delays.

KYC & Verification 

We understand that verification timing can vary depending on where a platform is licensed. For example, UK-licensed sites must ask for KYC details right away, whereas offshore operators tend to wait until you make your first withdrawal.

We test the document upload process and note how long it takes to get approved. Our testing process here involves recording when verification starts, the level of requested information, and how clearly the site explains the process.

Limits and Fees

We look beyond headline payout speed to the numbers that determine what you actually get to keep, and how quickly.

• Minimums and maximums: Every payment review records the minimum deposit and withdrawal amounts, along with daily, weekly, or monthly caps. Low minimums suit casual punters, while high maximum limits work better for high rollers.

• Fees and deductions: We examine transaction fees, currency conversion costs, crypto network charges, and any other deductions specific to withdrawals. One key check is whether withdrawing in instalments exposes you to repeated fees, or whether a restrictive payout schedule risks trapping a large win.

• Clarity of terms: These conditions need to be easy to find and understand before you deposit. We like to see flexible limits, but clear, upfront terms matter more. Hidden fees, jargon-heavy language, or buried restrictions all cost points.

Safety, Security and Fair Play (20%)

While regular promotions with reasonable terms and colossal product selections are pluses, nothing compensates for weak customer protection. While Safety accounts for 20% of the Final Score, it’s also a standalone pass-or-fail test. We will never recommend a site that fails our core licensing, security, or fair play checks, even if it gets top marks in every other category.

Licensing and Regulation

Whether we’re reviewing casinos, betting sites, or poker rooms, we check licensing claims directly rather than taking them at face value.

• Accepted regulators: We’re happy with licensing from recognised regulators such as the UK Gambling Commission (UKGC), Curaçao Gaming Authority (CGA), Malta Gaming Authority (MGA), and the Gibraltar Gambling Commissioner (GGC). We also accept licensing from comparable regulators that enforce meaningful standards.

• Verifying the licence: Instead of relying on a logo or licensing information in the footer, we either follow the licence link or search the regulator’s official register. This confirms the licence is active, covers the right gambling product, and lists the domain we’re reviewing.
  

• Rules and protections: We examine the rules surrounding ID checks, how sites handle your funds, responsible gambling, and the complaints procedure. We expect access to an approved Alternative Dispute Resolution (ADR) service where applicable.

Fair Play and Auditing

Here’s how we review each product:

• Online Casinos: When reviewing casinos, we look for independent random number generator (RNG) testing and published audit information, while opening game information screens to see how easy it is to find RTP data.
• Betting Sites: Our testing focuses on bet settlement. We inspect the rules relating to palpable errors, void selections, abandoned events, maximum payouts, and account restrictions. Terms must define these situations clearly and not give the bookie unreasonable freedom to cancel legitimate winning wagers.
• Poker Rooms: We look at how each platform approaches issues such as collusion, chip dumping, bots, and multi-accounting. Top sites have clear prohibited-play rules, active monitoring, and a credible reporting process.
• Crypto Gambling Sites: We check provably fair games and whether it’s possible to view the server seed, client seed, and nonce, then reproduce the result via a working verification tool. Although provably fair technology offers transparency, it doesn’t replace licensing or independent oversight.

Responsible Gambling

We check for deposit and loss limits, session controls, reality checks, time-outs, and self-exclusion. It’s also essential that these tools are easy to find and readily accessible, rather than having to contact support to complete an action.

Our reviewers test the controls available within the account and confirm if the changes take effect as described. We also note how clearly the site explains cooling-off periods, limit increases, and the consequences of self-exclusion. We’re not impressed if any tool is buried in the terms or requires additional steps.

Furthermore, we check for direct links to recognised external support groups and national self-exclusion schemes when applicable. Sites that provide vague, outdated, or hard-to-reach safe gambling information score poorly.

Account Security

Our team confirms that the website uses encrypted connections. We also inspect the level of security surrounding registration, login, and payments. Most highly rated sites provide two-factor authentication and allow you to activate it without talking to a team member.

Testing also covers password requirements, account recovery procedures, and alerts for important account changes. We find out if sites handle your payment information through reputable processing systems, and whether there’s a secure upload route for sensitive documents.

Finally, we sacrifice our sanity by reading the privacy policy to establish what personal information the operator collects, why it’s processed, how long it’s retained for, and whether it’s likely to get shared with third parties. We want to see clear explanations, not jargon that requires a thesaurus or help from a legal expert to understand.

Operator Reputation

We’re never taken in by a brand ‘name’ and always judge organisations on their merits. Our team identifies the company behind the site and investigates its trading history, ownership, and related gambling brands. With this information, we can spot inexperienced operators, frequently rebranded businesses, and problems across sister sites.

Another part of this process involves checking public regulatory records for warnings, licence suspensions, financial penalties, and other legal issues. While we don’t automatically fail a site for a past sanction, it does impact our perception, and we consider its seriousness, when it occurred, and how the operator reacted.

Bonuses, Promotions and Rewards (15%)

We don’t fall for the gigantic headline bonus trick. Sure, a 200% bonus worth up to £5,000 looks good on paper. But if the terms aren’t fair, this promo is as much use as an underwater hairdryer. That’s why we calculate what you can achieve after meeting the qualifying terms.

Bonuses account for 15% of the Final Score because, while they can improve a high-quality gambling site, they don’t act as a lifeboat for a weak one. Our team compares welcome offers, ongoing promotions and loyalty rewards while checking every important restriction.

Welcome Bonus

• For Casinos: We look at the match percentage, maximum bonus, minimum deposit, and the number and value of any free spins. From there, we calculate how much needs to be wagered to cash out, the list of qualifying games, and how much of the final balance we can withdraw.
• For Sportsbook: Our review process covers free bets, enhanced odds, and deposit-based promos. We find out if the qualifying stake is returned with the winnings, the minimum odds requirement, and whether you need to place a single bet or complete several stages before receiving the full reward. 
• For poker rooms: We check deposit matches, ticket packages, and newcomer tournaments. Since poker bonuses tend to clear gradually through real-money play, we calculate the level of activity needed to unlock each portion. We give little credit to massive bonuses that can only be fully claimed by ultra-high-volume players. 

House Rules: Terms and Wagering Requirements

Our House Rules provide an insight into the real value of promotions. We read the full terms and translate key conditions into plain English before awarding a score. Platforms that include unclear or extremely restrictive terms earn a low total, and we flag any conditions that weaken the offer. This is especially true when the promo gives us a misleading impression of its attainable value.

• Casino Offers: We find out if wagering applies to the bonus alone or the deposit and bonus combined. We also check game contribution rates, expiry periods, maximum bets, excluded titles, and caps on the amount you can withdraw.
• Sports Betting Bonuses: We assess minimum odds, qualifying markets, settlement rules, and any noteworthy restrictions on cash-out or combo bets. We also check how quickly free bets expire, and whether the platform includes the original stake in the return.
• Poker Bonuses: We look at the points or rake needed to access bonus funds, the clearing window, and if rewards are unlocked in useful increments. We check tournament tickets for expiry days, eligible events, and whether you can exchange them if a scheduled game gets cancelled.

Loyalty and Ongoing Rewards

The best gambling sites ensure you get value for money long after you’ve used the welcome package. We look for ongoing promos such as reloads, cashback, free spins, free bet clubs, prize draws, tournaments, and seasonal bonuses. Our goal here is to see how frequently you receive something worthwhile.

With cashback, we look at the percentage of net losses you get back, limits on how much you receive, and whether you receive it in cash or restricted bonus credit. For recurring promos and free bet clubs, we compare the qualifying spend with the reward’s value instead of viewing every giveaway as a benefit.

We examine loyalty tiers, including how you earn points, progression speed, and whether you can earn useful rewards through a realistic level of activity. Ideally, a site will clearly outline the number of levels, what you must do to level up, and what you receive once you get there.

Rakeback is massively important for regular poker players, so we compare the effective return, eligibility rules, and payout frequency, while analysing leaderboard prizes and tournament tickets. We’ll even outline when we use our outstanding poker skills to win prizes, although you probably shouldn’t hold your breath on that one!

Mobile Experience and Usability (10%)

A high-quality gambling site will work 24/7, no matter what device you use to access it. We test the complete mobile journey, from sign-up and account verification to playing, claiming bonuses, and withdrawing.

Menu Navigation and UI

We discover how easy it is to reach the game lobby, sportsbook, poker tables, cashier, promos, and account controls via a mobile browser or app. Top-rated platforms allow you to access their core features without requiring you to repeatedly open menus or switch to the desktop site.

What we test varies depending on the site’s offering:

• Casinos: Game search, category filters, and returning to recently played games or favourites.
• Sportsbooks: Ease of finding an event, adding selections to the bet slip, or building/editing an acca.
• Poker: Finding suitable tables and tournaments by game, format, stake, or buy-in.

It’s important that text, buttons, and betting controls are highly visible on a small screen. Sites lose points if they provide cluttered menus, intrusive pop-ups, difficult scrolling, or hide important information outside the visible display. Our team also checks to see if you can reach payment, verification, and safer-gambling settings without speaking with support.

Performance

Our team measures how quickly pages, games, and account features load during standard mobile use. We conduct testing on mid-range devices instead of relying on top-of-the-line phones to give us a realistic picture of everyday performance.

Here’s an overview of how we test performance:

• Casinos: We launch a sample of slots, table games, and live dealer streams, keeping an eye out for freezing, disconnections, or long loading screens.
• Sportsbooks: We look at odds updates, in-play bet placement, the responsiveness of cash-out, and the stability of live streams.
• Poker: The stability of gameplay, reconnection speed, and feature parity. We also find out if it’s possible to play multiple tables, view tournament information, or adjust bets easily.

We rate consistent performance as being far more important than a single quick loading time. Platforms that experience repeated crashes or offer unresponsive controls fare poorly in this ranking category.

Native Apps vs. Mobile Browser

We check if the operator has downloadable apps for iOS and Android, where you can download them, and how closely mobile play matches the desktop experience. While some platforms let you download software directly from their websites, official App Store or Google Play availability leads to easier installation.

Indeed, our team pays special attention to sideloaded apps and verifies that the download comes from the licensed operator’s official domain. We also ensure that installation instructions are clear and that you’re told which device permissions are required.

We don’t automatically award higher scores to native apps. Regardless of the format the platform chooses, we compare it with the desktop version. We don’t expect to see missing games, reduced betting markets, limited cashier functions, or absent security or safety-gambling tools.

Player Support (10%)

If something goes wrong, you need reliable support. Whether you experience a cashier problem, a disputed bonus, or have your account restricted, it’s essential to have someone available to explain what’s going on. A platform’s customer support standard tells a tale about what it really thinks about its players.

Channels and Availability

24/7 live chat is a minimum expectation, and we also check for other support options, including email and phone, while recording the opening hours for each. We’re unimpressed with limited schedules and mark down any site that takes aeons to respond to basic queries.

With live chat, our reviewers record how long it takes to reach an agent, taking note of chatbot loops, dropped conversations, and any requirement to log in before getting help.

When it comes to email testing, we measure how long it takes to even receive an acknowledgement of our message, and the time taken to receive a useful answer. When phone support is available, we confirm the regions the number works in and whether the site clearly states opening hours and charges.

Quality of Assistance

While we value fast responses, their impact is diluted if the agent is unable to answer questions effectively. We start with fairly basic queries regarding payments, verification or bonus terms.

Then we ramp things up a notch by addressing complex issues involving delayed payouts, disputed promotions, and account restrictions. Although we don’t expect front-line agents to have a 100% success rate, we do anticipate that they’ll explain the next steps, create a traceable ticket, and offer a realistic escalation timeframe.

In our experience, the top sites have agents who understand the product, give consistent answers, and take ownership of the question. We deduct points for scripted replies, contradictory information, and repeated transfers.

Guides and Self-Help

The best support begins long before you contact a live chat agent. That’s why we check out the site’s FAQ or help centre sections to see their depth, organisation, and accuracy.

High-quality resources explain registration, account verification, deposits, withdrawals, bonus rules, account security, and responsible gambling in easy-to-understand language. We take note of sites that provide step-by-step guides reflecting the current website, not an older interface.

We follow links to important terms and policies to see how easy it is to find the information we need. Our team doesn’t want to see broken pages, outdated limits, and nonsensical answers.

Language and Regional Support

Finally, we distinguish genuine local-language assistance from an interface or chatbot that has been machine translated. Whenever a site advertises multilingual support, we test whether an agent understands our questions and responds naturally in the selected language.

We also expect support staff to recognise the payment methods, currencies, identity documents, and payout expectations relevant to your location. They also need to have the ability to identify the right regulator, dispute route, and responsible gambling services for that market.

Meet the Reviewers

We only use specialist gambling writers and researchers with hands-on experience of online casinos, sportsbooks, and poker rooms to produce our reviews. Their extensive knowledge covers game testing, betting markets, poker formats, bonus terms, payment systems, licensing, and responsible gambling.

Find our more about our authors:

• Dean Russell
• Johanna Gullberg

In each case, our reviewers complete the playthrough and record the results against our weighted scoring framework. They include evidence from real transactions, support conversations, game or betting sessions, account checks, and the website’s published terms. Our scoring only reflects what our team can verify, and doesn’t take into account a site’s claims.

A second editor checks each review for accuracy, consistency, and balance before publication. This process involves double-checking key details such as licensing, bonus conditions, payment limits, and score calculations. The editor also confirms that the final written verdict matches the evidence and ensures that comparable sites have been judged by the same standards.
