Editorial Policy and Research Methods
The Mines guides methodology distinguishes documented game facts from mathematical examples, interface observations and unresolved questions. Each type of evidence supports a different kind of statement.

Primary sources and exact versions
Developer documentation is used to identify a game and its published features. Operator pages can establish what an operator lists, while regional information requires a source that actually applies to that market.
A provider catalogue does not prove that a Canadian casino carries the game. An operator brand in a keyword list does not prove availability. When titles overlap, the provider and game identifier take priority over similar artwork or symbols.
Research versus testing
Reading a product page is described as research. An interface observation is limited to the controls or states actually inspected. A demo button is not reported as a successful launch unless the game loaded and the relevant behaviour was checked.
The reviews do not include real-money play tests. Product overviews are not presented as accounts of personal gambling experience.
Probability and verification examples
Mathematical examples state their assumptions. The fixed-board probability calculations were checked using separate combinatorial and sequential calculations, with small-board enumeration as an additional check.
The seed example uses invented inputs and was reproduced independently in Python and Node. That checks agreement in the calculation; it is not an audit of a live casino round or a test of predictor accuracy.
Uncertainty and conflicting figures
Settings without a reliable source are omitted or explicitly identified as unconfirmed. Where a source lists a range or several configurations, the most attractive value is not silently selected as a universal figure. A publication date, an access date and a game release date are treated as different facts.

Corrections and updates
A correction should identify the affected claim, the exact version and the evidence replacing it. Removing an unsupported number is preferable to preserving it for a keyword target. Changes to an operator’s catalogue or terms require a fresh check of the affected statement, rather than an automatic date refresh.
Commercial claims
An informational source link is not evidence that a casino has been tested or recommended. Rankings, bonus promises and claims about commercial relationships require their own documented basis; they are not inferred from inclusion in a guide.
Authorship and review status
The author and editor are named in the credits below and on the editorial team page. Their roles are separate from claims of professional qualifications, live-game testing or review of every external offer. See About this site for the scope of the guides.
Keyword and search-demand evidence
English keyword variants help organise reader questions. They do not establish that a game, bonus, app or predictor feature exists. Search phrasing guides the questions covered, but popularity is not inferred from a title, translated phrase or catalogue listing. The site does not present its directory as a measured popularity ranking.
The Mines review methodology prioritises the exact product and a useful answer. Where the evidence cannot support a requested feature, the page explains that limit rather than inventing a number or repeating a keyword as a substitute for information.
