The Casino Content Evidence Register

An evidence register is a spreadsheet that links every material claim on a page to the source that supports it, with the date it was checked and when it must be checked again. For casino content, where bonus rules and advertising codes change, it is the simplest way to stop old pages drifting out of date.

Why gambling content needs one

A single bonus page can contain a wagering requirement, a market restriction, a payment rule and a responsible-gambling message, and each can change independently. In Great Britain, for example, new limits on bonus wagering requirements took effect on January 19, 2026, so any page written before then that describes higher requirements as normal became outdated on that day. A register makes that kind of change findable: filter by claim type and market, and every affected page appears.

Grade every source

Use the five evidence grades from our quality framework. A rule needs a grade A source: the regulator's own page, the statute or the advertising code. A law firm briefing (grade C) is a good way to find the rule, but link and quote the rule itself.

Set review dates by risk

  • Monthly, and on any announced change: bonus terms, advertising rules, licensing status, payment availability.
  • Quarterly: product facts such as game RTP information supplied by studios, platform features.
  • Yearly: evergreen explanations, glossaries, how-to guides without rules.

Google warns against "changing the date of pages to make them seem fresh when the content has not substantially changed", so update the visible "updated" date only when the content changes, and keep the check date in the register.

Sample rows (invented)R-014 | /guides/welcome-offers-gb | "Wagering requirements are capped at 10 times" | Great Britain | Rule | LCCP SR 5.1.1 | checked 2026-10-25 | next 2026-11-25

Questions

What counts as a material claim?

Any statement a reader could act on or that could mislead if wrong: rules, bonus terms, prices, dates, statistics and safety information. Opinions and plain explanations do not need a row, but anything quoted does.

Should the check date be shown on the page?

For rules and offers, yes. Readers and reviewers need to know when a requirement was last confirmed, separate from when the article was published.
