How We Rate Online Casinos

How We Rate Online Casinos

We use a consistent rating system so that readers can see not only an online casino's overall score, but also how that score was determined. Each casino is assessed across a number of individual categories. The results are then converted into scores ranging from 1.0 to 5.0.

A casino's overall rating is not based solely on the size of its bonus, the number of games it offers or the design of its website. Among other factors, we consider legal transparency, withdrawals, payment methods, bonus terms, game selection, mobile usability, the platform's technical performance, customer support and other aspects that directly affect the user experience.

Since 14 August 2026, all new and re-reviewed casino reviews have been assessed using this standardised methodology. Older reviews published before the system was introduced are not automatically assigned a score retrospectively. A rating is added only when the casino has been reassessed against the current criteria.

How Our 5-Point Rating System Works

Each category receives a score from 1.0 to 5.0. We use the following scale as a guide:

A score of 5.0/5 does not mean that a casino is perfect in every respect. Rather, it indicates that our assessment identified no significant weaknesses within that particular category.

Likewise, a score of 4.5/5 is by no means a poor result. It generally means that the most important features are implemented well, but one or more factors prevent the casino from receiving the maximum score.

Which Categories Make Up the Rating

In a standard casino review, we primarily assess the following areas:

• trustworthiness, licensing and legal transparency;
• bonuses and promotions;
• game selection;
• payment methods;
• withdrawal speed and terms;
• design and usability;
• loading speed and technical performance;
• mobile usability;
• casino app;
• customer support.

Additional criteria may apply depending on the type of casino. For crypto casinos, for example, we examine cryptocurrency payments in greater detail. When reviewing casinos that promote fast withdrawals, we place greater emphasis on actual processing times, withdrawal limits and the KYC procedure.

Not All Criteria Carry the Same Weight

The overall rating is not a simple average of all individual scores.

We believe that criteria affecting the security of a player's account and access to deposited or won funds should carry more weight than factors such as website design or the availability of a dedicated mobile app. We therefore apply the following weighting:

The total weighting is 100%.

Trustworthiness and withdrawals carry the most weight because they decide whether a player's account is safe and whether they can actually get their money out. 

Technical and usability criteria (mobile usability, design, loading speed and the app) together account for about 23% of the overall rating, so a polished platform alone cannot produce a high score.

This distribution prevents a casino from receiving a very high overall rating solely because of an attractive design, a large bonus or an extensive game catalogue when, for example, its withdrawal terms are poor or important legal information is insufficiently transparent.

How We Calculate the Overall Rating

Each category score is multiplied by its weight; the contributions are summed and rounded to one decimal place. For example, a casino might receive the following scores:

We do not round up: 4.56 is published as 4.6/5, not 4.7/5.

Our Step-by-Step Testing Process (Player Journey)

We don't rate casinos from a desk. Our team registers real accounts, deposits real money and follows the same journey a Canadian player would take, from sign-up to cashing out. Every step is time-stamped, so our reviews reflect what actually happened on the day we tested, not what the casino's marketing says.

Step 1: Registration. We create an account using Canadian details and record how long the process takes. We also note exactly when the casino asks for KYC documents: at sign-up, before the first deposit or only at withdrawal.

Step 2: Deposit. We fund the account with real money. We check which payment methods are offered, what the minimum and maximum limits are, how quickly the funds arrive, whether any fees apply and whether the process includes unnecessary extra steps.

Step 3: Bonuses. We read the bonus Terms and Conditions in full, then check whether the wagering requirement can realistically be completed. We look at the maximum bet, the validity period and the list of excluded games, and compare them with what the promotion page claims.

Step 4: Game library. We go through the game categories and providers, try demo modes where they are available and play a selection of titles to see how they perform on desktop and mobile.

Step 5: Withdrawal. We request a real withdrawal, using different payment methods where possible. We measure the actual time from request to receipt and note every KYC requirement or additional check along the way.

Step 6: Customer support. We contact support through every available channel, including live chat and email. We record how quickly the agent replies and whether the answers on bonuses, KYC and withdrawals are accurate and clear.

Step 7: Retesting and updates. Casinos change their terms, limits and payment options, so we return to them regularly. When something changes, we update the score and the date on the review.

Everything above is done with real money and real accounts. You can see how we apply this process in our reviews of Slotoro Casino and Jet4Bet Casino, where our expert made real deposits and withdrew real winnings.

Trustworthiness, Licensing and Legal Transparency

This is one of the most important categories in our rating system.

Among other things, we assess:

• the operating company;
• the company's registered location;
• the stated gambling licence;
• the relevant regulatory authority;
• the availability of legal information;
• the Terms and Conditions;
• the Privacy Policy;
• age restrictions;
• regional restrictions;
• the KYC procedure;
• the transparency of rules governing player accounts and balances;
• responsible gambling tools (deposit limits, self-exclusion, reminders about time spent playing).

Casinos receive a high score when the operator, licence and legal framework are clearly stated and easy to verify, and when responsible gambling tools are easy to find and simple to activate.

Incomplete legal disclosures, conflicting information across different pages, a lack of clarity regarding the company actually operating the platform, or the absence of basic responsible gambling tools will negatively affect the rating.

Bonuses and Promotions

When rating a bonus, we look beyond the maximum advertised value and focus primarily on how usable the offer is in practice.

We assess:

• the bonus amount;
• the number of free spins;
• the minimum deposit;
• wagering requirements;
• the maximum permitted bet;
• the validity period;
• excluded games;
• potential winnings limits;
• required bonus codes;
• cashback;
• reload bonuses;
• VIP offers;
• other regular promotions.

A casino offering a 500% bonus will therefore not automatically receive a higher rating than one offering a 100% bonus.

If a large bonus comes with very high wagering requirements, a low maximum bet or substantial withdrawal restrictions, its actual appeal is rated accordingly lower.

Game Selection

When assessing a casino's game selection, we do not consider only the total number of available titles.

Among other things, we evaluate:

• the size of the game catalogue;
• the number of software providers;
• slots;
• live casino games;
• table games;
• game shows;
• crash games;
• jackpot games;
• search functionality;
• filters;
• game categories;
• game availability in the relevant market;
• game fairness (independent audits such as eCOGRA or iTech Labs, and published RTP figures).

A casino with 15,000 games may therefore receive a lower rating than a platform with 8,000 titles if its larger catalogue is poorly organised, its search function is limited or a substantial proportion of its games is unavailable to users in the relevant country.

Payment Methods

We assess deposit and withdrawal options separately.

We examine:

• bank cards;
• e-wallets;
• bank transfers;
• local payment methods;
• cryptocurrencies;
• the minimum deposit;
• the minimum withdrawal;
• supported account currencies;
• potential fees;
• whether each method is available for both deposits and withdrawals.

Higher ratings are awarded to platforms that support relevant payment methods commonly used in the applicable country and do not create unnecessary obstacles to financial transactions.

Withdrawal Speed and Terms

Withdrawals are among the most important components of our rating system.

We analyse:

• the processing time stated by the casino;
• the actual processing time, where a practical test has been conducted;
• the minimum withdrawal amount;
• daily, weekly and monthly withdrawal limits;
• available withdrawal methods;
• KYC requirements;
• potential additional checks;
• fees;
• restrictions related to bonus funds.

If a casino claims that withdrawals are processed within a few hours but our test shows that the actual processing time is significantly longer, our rating is based on the real-world result.

We also distinguish between the casino's own processing time and any additional time a bank or payment service provider may require before the funds are finally credited.

Design and Usability

We do not rate a casino's design solely on whether its website is visually appealing.

Usability is the decisive factor.

We assess:

• the structure of the main menu;
• access to the cashier;
• game search;
• filtering options;
• the bonus section;
• the user account;
• navigation;
• readability;
• the logical placement of key features.

Even a modern, visually sophisticated website may receive a lower score if users struggle to find important information or basic features are unnecessarily complicated.

Loading Speed and Technical Performance

We test how quickly and reliably the casino platform performs in real-world use.

Among other things, we examine the loading times of:

• the homepage;
• the game catalogue;
• the bonus section;
• the cashier;
• the user account;
• individual games;
• the mobile version.

Delays when switching pages, lagging elements, unstable menus and other technical issues are also taken into account.

Our speed rating is based on actual use of the platform, not solely on the result of a single automated performance test.

Mobile Usability

The mobile version of a casino is assessed separately from its desktop version.

We examine:

• responsive design;
• the mobile menu;
• speed;
• the game catalogue;
• search functionality;
• games;
• the cashier;
• deposits;
• withdrawals;
• the user account;
• live chat.

If users can comfortably access all essential features on a smartphone without having to switch to the desktop version, the casino receives a correspondingly higher rating.

Casino App

We regard a dedicated app as an additional feature. This category therefore carries a relatively low weighting in our overall rating.

We assess:

• whether a dedicated app is available;
• Android support;
• iOS support;
• the installation process;
• stability;
• the game selection;
• payment options;
• login;
• the range of available features.

The absence of an app is not a serious disadvantage as long as the casino's mobile website reliably provides all essential features.

For this reason, the lack of an app can have only a limited effect on the overall rating.

Customer Support

We rate customer support based on the actual contact options available and the quality of the responses received.

We assess:

• live chat;
• email;
• other contact options;
• service hours;
• time to first response;
• response quality;
• the support agent's expertise;
• available languages.

A fast response alone is not enough to earn a high score.

For example, if an agent responds within 20 seconds but cannot clearly answer questions about bonus terms, KYC or withdrawals, this will negatively affect the rating.

When the Overall Rating May Be Capped

In certain cases, a casino cannot receive a very high overall rating regardless of strong results in other areas.

This applies in particular to serious issues involving:

• legal transparency;
• withdrawals;
• hidden restrictions;
• blocked or withheld funds;
• discrepancies between published terms and actual practices;
• user account security.

A large game catalogue, an attractive bonus or an excellent mobile experience cannot offset a serious deficiency in any of these areas.

In such cases, our editorial team may impose a cap on the maximum overall rating a casino can receive.

For example, a casino with a serious withdrawal issue cannot achieve an overall rating of 4.8/5 solely on the strength of high scores for games, bonuses and mobile usability.

Casinos We Don't Recommend (Blacklist)

Some casinos are excluded from our recommendations entirely, regardless of how their bonuses or game catalogue might look on paper. A casino ends up on our blacklist when we find evidence of serious, repeated problems that put players' money or safety at risk.

We add a casino to this list when we identify:

• unpaid or withheld withdrawals, including cases where a casino delays payment indefinitely or invents new requirements after a withdrawal has been requested;
• a fake, expired or unverifiable gambling licence, or no licence at all;
• unfair or unaudited games, where RTP is not published and no independent testing lab is named;
• bonus terms that are hidden, buried in unrelated pages, or that contradict what is advertised on the promotion itself;
• customer support that is unreachable, unhelpful or gives misleading answers about withdrawals or KYC;
• disregard for self-exclusion requests, where a player who has asked to be excluded is still able to deposit and play.

Typical patterns we've seen include a casino that stops responding to withdrawal requests once the amount exceeds a certain threshold, a casino that changes its wagering requirements after a bonus has already been claimed, and a casino that continues to send marketing emails and allow logins to an account that requested self-exclusion. We name a specific casino on our blacklist only when we've verified the issue ourselves; where we haven't, we describe the pattern rather than naming a brand.

If you come across a casino showing any of these signs, the safest move is to stop depositing, request a withdrawal of any remaining balance in writing, and avoid the platform going forward. Screenshot your correspondence in case you need to file a complaint with the relevant regulator or payment provider.

Where Our Information Comes From

For our ratings, we primarily use information available directly from the casino.

This includes:

• the official website;
• the Terms and Conditions;
• bonus terms;
• payment information;
• legal disclosures;
• the user account;
• customer support.

Where possible, we also test certain features ourselves. We also check that basic player data protections, such as SSL encryption and a clear privacy policy, are in place.

If important information cannot be reliably verified, we do not present it as an established fact. Missing or conflicting information may also affect the transparency score within the relevant category.

Are Our Ratings Influenced by Partnerships?

Yes, we have commercial relationships with some of the casinos we review. This is how our website is funded, and we're not going to pretend otherwise.

What this does not do is influence a casino's score, our criticism of it, or where it appears in our rankings. A casino cannot pay for a higher rating, a better position on a list, or the removal of a negative point. There is no arrangement, anywhere in our process, that lets a commercial relationship change a number on the page.

Every rating comes from the same source: the testing process and the fixed category weightings described above. A casino's score is calculated the same way whether we have a commercial relationship with it or not, and the weightings themselves don't shift to favour anyone.

Our editorial team, which tests casinos and writes reviews, is kept separate from the commercial side of the business. The people deciding a casino's score are not the people negotiating partnerships with it.

The clearest proof of this separation is simple: a casino we have a commercial relationship with can still end up on our blacklist if it fails to meet our standards. Partnership status has never protected a casino from a poor rating, and it never will.

Responsible Gambling and How It Affects Our Ratings

The presence and quality of responsible gambling tools directly affects a casino's Trustworthiness score. We check whether a casino offers deposit, session and loss limits, self-exclusion, reality checks and time-out options, and how easy these are to find and activate.

This isn't an optional extra we note in passing. We treat it as a mandatory part of our assessment, on the same footing as licensing and legal transparency. A casino with an attractive bonus and a large game catalogue but no meaningful way for a player to limit their deposits, set a loss limit or exclude themselves will score lower on Trustworthiness as a result, regardless of how well it performs elsewhere.

We also check whether a casino makes it easy to walk away, not just to spend. A "take a break" option, clear reminders about time spent playing and a straightforward self-exclusion process all count in a casino's favour.

For Canadian players, we point to established support services: ConnexOntario (1-866-531-2600), the Responsible Gambling Council (RGC) and CAMH.

Minimum age requirements vary by province: it's 19 in most of Canada, including Ontario and British Columbia, and 18 in Alberta, Manitoba and Quebec. Whatever the platform, gambling should be treated as entertainment, not as a source of income.

How We Localise Reviews for Canadian Players

Our reviews are built specifically around the Canadian market, not adapted from a generic template.

We check whether a casino supports payment methods Canadian players actually use, such as Interac, iDebit and InstaDebit, rather than only international cards and e-wallets. We also confirm whether accounts and transactions are handled in CAD, and whether the interface and customer support are available in English and French.

Legal status varies significantly across the country. Ontario has its own regulated market, overseen by AGCO and iGaming Ontario, and casinos licensed there operate under different rules than offshore platforms serving other provinces. Some sites also operate under a Kahnawake licence. We note which framework applies to a given casino, since a regulated Ontario-licensed operator and an offshore site are not held to the same standards.

We also flag regional restrictions and the minimum age to gamble — 19 in most provinces and 18 in Alberta, Manitoba and Quebec — so Canadian readers know upfront whether a casino is actually available and legal where they live.

Ratings Can Change

Once assigned, a rating is not permanently fixed.

Online casinos regularly change their:

• bonus offers;
• limits;
• payment methods;
• KYC requirements;
• game catalogues;
• mobile solutions;
• legal disclosures;
• withdrawal rules.

Following a reassessment, a rating may therefore either improve or decline.

For this reason, our casino reviews include the date of the assessment or update. This allows readers to see how current the published information is.

What Happens to Older Casino Reviews

Even before this methodology was introduced, our casino reviews covered bonus offers, games, payment methods, withdrawals, licensing information, mobile usability and other important features. At that time, however, the findings were not converted into individual numerical scores.

We do not assign ratings to older articles retrospectively.

Since 14 August 2026, a numerical score has been assigned only after a casino has undergone a new or repeat assessment under the current methodology.

During the transition period, our website may therefore feature all of the following types of casino reviews at the same time:

• new reviews with a rating;
• older reviews that have been reassessed and now include a rating;
• older reviews without a numerical rating.

The absence of a score from an older review does not mean that the casino was not assessed at the time. It simply means that the article has not yet been reassessed under the new standardised rating system.

What the Overall Rating Means

An overall rating such as 4.6/5 summarises the results across all assessed categories, taking their respective weightings into account.

However, the overall score should not be viewed in isolation.

For example, a casino with an overall rating of 4.6/5 might receive the following individual scores:

• 4.9/5 for games;
• 4.8/5 for mobile usability;
• 4.7/5 for withdrawals;
• 4.1/5 for bonuses.

Another casino with the same overall rating may have a completely different balance of strengths and weaknesses.

For this reason, our casino reviews display both the overall rating and the individual category scores.

This allows readers to understand how a casino earned its score and decide for themselves which strengths and weaknesses are most relevant to their own needs.

Meet the Team / Why Trust Casino Zeus

Liam Beaumont writes casino reviews at Casino Zeus, with a focus on the Canadian market. He came to gambling from freelance esports copywriting — one assignment happened to touch on online casinos, and he never looked back. 

Since joining Casino Zeus in January 2026, he has published 50+ reviews, each built around hands-on testing: he loads up the lobby himself, checks RTP and volatility on the slots, works through the table games and live-dealer studios, and tests the operator's payments, licensing and account security along the way. His focus stays on the games because that's where marketing and reality most often part ways.

Why trust us

• We test casinos with real accounts and real money, not just by reading their terms.
• Our category weightings are fixed and published, so a casino can't change how it's scored.
• We retest casinos regularly and update ratings when something changes.
• Our reviews are built specifically for Canadian players, from payment methods to provincial licensing.
• Editorial and commercial teams are separate, and a partner casino can still end up on our blacklist.
