Contact the editors
Spotted a figure that looks wrong, or want to know how one was worked out? Write to us. There is no form and no account: just an email address.
Our email address
Email is the way to reach the editors. Write in plain text if you like; there is no need for a subject line in any particular form. We will never contact you first to ask for personal or payment details, and if a message claiming to be from us asks for either, it is not genuine.
What to write to us about
Corrections
Accuracy is the whole point of this site, so a report of an error is the most useful message we can receive. To help us check it quickly, please tell us three things: the page (the address in your browser is ideal), the figure you think is wrong, and what you believe it should be. If you worked it out yourself, a line or two of your working helps, whether that is a probability, a count of combinations or a quote from a game's rules.
A reported figure is recalculated from the rules of the game, and if we have made a mistake the page is corrected. Where a figure stands, the reason is usually a difference in rules: blackjack tables vary, some roulette tables offer La Partage and some do not, and lottery operators publish odds rounded in their own way. Our how we calculate the odds page sets out the assumptions behind each game and is worth a look first.
Questions about the maths
If you would like to understand how a figure is reached, ask. Questions such as why the tie at baccarat is so expensive, why the pass line and don't pass lines have different edges, or how the two rounds of Lotto change the jackpot odds are exactly what this site is for. Good questions often become improvements to a page, so they help other readers too.
Rule changes
Games change. If a UK lottery changes its matrix, price or prize tiers, or you notice that a rule we describe as common has become rare, let us know. The UK lottery odds page and the pages for each draw say which version of the rules they use.
What we cannot help with
We are a reference about odds, not a gambling company, a regulator or a support service, so some problems need to go elsewhere.
- A dispute with a casino or betting company. We have no relationship with any operator and cannot look into an account, a payment or a game result. Complain to the operator first, using its complaints procedure. If that does not resolve it, a company licensed in Great Britain must tell you which independent alternative dispute resolution (ADR) provider handles its unresolved complaints, and you can take the case there free of charge.
- Worries about gambling. If gambling is causing you or someone close to you harm, the National Gambling Helpline on 0808 8020 133 is free and open 24 hours a day. Our responsible gambling page lists more free services.
- Predictions and tips. We cannot tell you which numbers will be drawn or which bet will win next. No one can: each spin, deal and draw is independent of the last.
- Advertising and sponsored content. We do not accept advertising, paid links or sponsored articles, so there is nothing to discuss.
What happens to your message
We do not promise a reply or a time for one. The answer to a correction is the page itself once it has been changed, rather than a message back. We keep your email only for as long as we need it to deal with what you have sent, and we never add your address to a mailing list or share it with anyone.
