Methodology
TopReview uses a conservative, repeatable process to turn public casino information into structured directory records. This page explains what enters the dataset, how fields are normalized, what our score means, and where the method stops.
1. Record eligibility
A casino record is eligible for publication when it is marked as active in the research dataset and contains a usable name, domain, and website. These minimum fields establish the identity of the record; they do not establish quality, legality in every jurisdiction, or an endorsement by TopReview.
Duplicate and near-duplicate entries are resolved around the operator identity and public domain. Historical brands or alternate domains may remain separate when collapsing them would hide a meaningful distinction.
2. Source hierarchy
We prioritize first-party operator pages and public regulator material for factual fields. Public affiliate pages may support affiliate destinations and contact details. Secondary sources can help locate a fact, but a repeated claim is not automatically treated as verified.
Source quality is field-specific. An operator can identify its current domain, while a regulator is the stronger source for the status and scope of a license. Where sources conflict or cannot be reconciled confidently, we use narrower language or omit the field.
3. Normalization
Source material is inconsistent by nature. Cryptocurrency names can appear as tickers, full names, or network-specific labels; license references can use regulator names, jurisdictions, abbreviations, or free-form text. We map clear equivalents into stable taxonomies so records can be compared and browsed.
Normalization does not turn an ambiguous statement into a stronger claim. The public page can preserve source-backed license text while taxonomy links use a consistent label. Unsupported inferences—such as assuming a license from an operator's location—are not added.
4. Editorial completeness score
The score describes record completeness, not casino quality. It runs from 3.0 to 5.0 and uses eight visible checks: official website, domain, directory date, source license text, normalized license references, listed cryptocurrencies, public affiliate destination, and public affiliate email. Every check uses the same weight.
A complete record can therefore receive a high score even when TopReview makes no claim about its products or reputation. Conversely, a lower score means fewer defined fields are available in the directory; it is not evidence of misconduct.
5. Evidence count
The number displayed beside the score is an evidence count. It combines completed checks with the visible license and cryptocurrency references attached to the record. It helps explain the amount of structured material behind a page.
It is not a customer review count, vote total, player sample, or measure of public sentiment. TopReview does not convert this number into invented user reviews, and the structured data identifies the assessment as an editorial review by TopReview.
6. Data we deliberately exclude
Public pages exclude raw research notes, source dumps, private or excessive contact information, wallet addresses, WhatsApp details, unverified traffic figures, and claims that cannot be expressed conservatively. Bonus language and promotional superlatives are not treated as durable directory facts.
Exclusion protects both accuracy and readability. A field being absent from TopReview does not prove that the underlying feature is absent; it means the field is not currently supported strongly enough for publication in this dataset.
7. Updates and corrections
Casino domains, licenses, payment support, and affiliate terms can change after publication. Records may be refreshed when new public evidence becomes available, but TopReview does not claim real-time coverage. Dates on the site describe directory records, not a guarantee that every field was rechecked on that date.
Correction requests should identify the exact URL, disputed field, and a public supporting source. We assess corrections against the same field definitions and source hierarchy used for initial publication.
8. Reader verification
Directory pages are a research aid, not a substitute for due diligence. Before using a casino, confirm the current domain, license status and permitted markets with the relevant regulator; review the operator's current terms; and check whether gambling is lawful where you live.
No methodology can remove the risk of stale public information. Our standard is therefore simple: publish what the dataset can support, label what the numbers mean, and avoid pretending to know more than the evidence shows.
