Editorial policy

Clear questions, traceable sources, and limits stated where they matter.

Sources and examples

We link the documents behind factual claims and favor the reporting body or original technical source. A supplier’s description remains a supplier’s description. Historical figures retain their reporting period; a new article date does not make them current data.

Worked mathematical examples are original teaching models. They are labeled as hypothetical and are not represented as the probabilities or performance of a real game.

Preparation and review

The initial explainers were prepared with AI assistance. Source references, arithmetic, and presentation are checked during preparation. We do not claim independent specialist review, interviews, hands-on product testing, or personal playing experience unless an article documents that work.

Dates and corrections

An update date reflects the saved article revision. It does not change the date of an underlying study or release. Substantive corrections should describe what changed and why; simply changing a date is not a content update.

For a correction, include the article URL, the disputed passage, and a supporting source. Source references and substantive corrections are kept with each article.

Commercial boundaries

This edition provides information and analysis. It does not accept wagers or provide a gambling account. The current collection has no sponsored rankings or paid placement. Any future sponsored material must be clearly identified.

Photography

Context photographs are not presented as evidence of an event or a particular US property. Credits and license records appear on our sources and credits page.
