Where Do the Facts on This Site Come From?
Game rules come from published rule sets and standard references for each game. Legal and regulatory points come from the Gambling Commission and from the text of the law on legislation.gov.uk. Every page lists the documents it relies on under Sources.
Read moreShow less about our sources
We go to the primary document. A rule about online slots is checked against the regulator’s own guidance, not against a news story about that guidance, and a point about the minimum age is checked against the section of the Gambling Act 2005 that sets it.3 (source) Where a primary document is not public, we say what we relied on instead.
Small numbers in the text link to the source for that sentence. Each source in the list names its publisher and the date we last checked it, so a reader can see how fresh the check is. A source that has moved or disappeared is replaced or the sentence that relied on it is removed.
How Are Odds and House Edges Checked?
Probabilities, payouts and house edges are calculated from the rules of each game and the number of possible outcomes. Where we use a published estimate instead, such as the effect of a single blackjack rule, the page says so and names the source.
Read moreShow less about figures
A calculated figure is shown with enough of the working that a reader can repeat it, for example 1 ÷ 37 for the single-zero roulette edge. Our page on how we calculate the odds sets out the methods in full, including the assumptions behind them.
We describe a house edge as a long-run cost, never as a prediction of a session. Short runs vary widely. No page on this site claims that a strategy or a betting system turns the odds in the player’s favour.
How Do We Handle Rules That Vary by Casino?
Where British casinos deal a game in different ways, a page gives the common version, names the alternatives and shows what each one does to the house edge. A venue’s own house rule is never presented as a national rule.

Deck numbers, doubling rules, table limits, dress codes and entry policies are set by each casino. When a page states one of these, it uses wording such as “usually” or “varies by venue”, and it points the reader to the sign on the table or the casino’s own website as the final word.
How Is UK Regulation Covered?
Pages about gambling rules in Great Britain rely on the Gambling Commission’s published standards, guidance and announcements, and on legislation.gov.uk. Each regulatory figure is given with the date it took effect.

The Gambling Act 2005 does not extend to Northern Ireland, which has its own gambling law. Where this matters, a page says which part of the UK a rule applies to. Online games offered in Great Britain must meet the Commission’s technical standards,1 (source) and we use those standards when a page explains how an online version of a game works.
How Are Commercial Links Kept Separate?
Casino links appear only on the homepage and on the comparison of UK online casinos. The game guides, the odds pages and the UK guides carry no casino links, and their content does not depend on any commercial relationship.

Every casino listed holds an active remote licence on the Gambling Commission’s public register, which we check before listing and again when we review the page.2 (source) The order of the list comes from four criteria with fixed, published weights: welcome-offer terms, the range of table games, the fastest listed withdrawal and the choice of payout methods. The method and each casino’s four ratings are shown on the comparison page.
A casino cannot pay to move up the list or to change what we write about it. Links to casinos are marked as sponsored and open in a new tab. The welcome offer of each casino is shown with its significant terms underneath, and the full terms on the casino’s own site always take precedence.
How Are Images Labelled?
Some illustrations on this site are generated for it rather than photographed. Each generated image carries a small “AI” badge, and its description says so, so it is never mistaken for a photograph of a real casino, table or person.

We do not show screenshots of casino games, and we do not use images of people. Diagrams of tables, wheels and card layouts are drawn for the site from the rules they illustrate.
What Happens When We Get Something Wrong?
Confirmed errors are corrected on the page as soon as we have checked them, and the date at the top of the page changes. Write to [email protected] with the page, the sentence and the source you rely on.
Read moreShow less about corrections
We check each report against the primary source before changing the page. A correction to a figure also updates every other page that uses the same figure, so the site does not contradict itself. If a report turns out to describe a house rule at one casino rather than a general rule, we may add it to the page as a variation.
How Often Are Pages Reviewed?
Pages are reviewed when a rule, a limit or a source changes, and the comparison of UK online casinos is checked at least once a month. The date at the top of each page shows when it was last updated.

Game rules change rarely. Regulation and casino offers change more often. That is why the regulatory pages give the date each rule took effect, and why the comparison page shows the date its data was last checked next to the list.
