Get in Touch With Us
This page explains how to contact the editorial team at Mastercard Online Casinos. We compare Mastercard-friendly online casinos for US readers, so most messages we get are about our reviews, our rankings or details that may have changed. Tell us what you need, and we will point you to the right answer or fix the page.
Adults only. Our content is written for readers aged 21 or older (18 or older where your state allows). Online casino play is legal only in certain US states, so check the rules where you live before you play.
Where to send your message
Use the contact form or the contact details shown in the site header and footer. We do not publish a phone line or live chat on this page. Please don't send card numbers, passwords, Social Security numbers or ID documents to us. We never need them.
We can't give a guaranteed reply time. We read every message, and a real person replies when a reply is needed.
What to include so we can answer faster
- The page address or the name of the casino you are asking about.
- A short description of the issue: a wrong detail, an unclear section or a missing topic.
- The date you saw it. Our pages were last fact-checked on Sep 30, 2026, and casino terms can change after that.
- Your state, if the question is about availability or rules.
- A screenshot or a link to the casino's own terms, if you have one.
What we can help with
- Corrections: A bonus, limit, payment rule or licensing detail that looks outdated or wrong. We review it against the operator's published terms and update the page where needed.
- Questions about our reviews: Why a casino sits where it does, or how we weigh deposit acceptance, security, withdrawals, games and bonus terms. Our rankings are editorial. Commission does not buy position.
- Topic suggestions: For example, a deeper look at card declines, 3D Secure checks or withdrawal options.
- Business and partnership enquiries: Introduce your company and what you propose. We may earn commission from some links, but that does not decide our rankings or our written verdicts.
- Broken links or display problems: Tell us the page and your device.
What we can't do
We are an independent comparison site, not a casino. That sets some limits.
| Issue | Who can help |
|---|---|
| Declined Mastercard deposit | Your card issuer first, then the casino's cashier support. Declines often come from the issuer's own blocking of gambling transactions. |
| Pending or missing withdrawal | The casino's support team. We can't see or change your account. |
| Bonus dispute or account closure | The operator. Keep your screenshots and read the bonus terms you accepted. |
| Card charge you don't recognize | Your bank or card issuer. |
| Legal or tax questions | A qualified professional. Nothing on this site is legal or tax advice. |
We can't recover funds, reverse a transaction or speak to a casino on your behalf. We won't endorse a casino based on a complaint we can't verify.
How we handle corrections and feedback
When you flag a problem, we compare your claim with the operator's current terms and with state or regulator information where relevant. If you are right, we correct the page and update the check date. If the terms differ by state or account type, we say so. We don't publish invented reviews or testimonials, and we don't claim to have deposited or withdrawn money at any casino. Our write-ups rest on research and on reviewing published terms.
Our ranked list includes Raging Bull, Magician Bet, Slots of Vegas, Uptown Aces and others. Bonus headlines change often and come with wagering, eligibility and cap conditions. Always read the terms on the casino's own site before you deposit.
If gambling is causing you problems
Gambling always carries a risk of losing money, and no casino or bonus changes that. Only play with money you can afford to lose. If gambling is causing stress, debt or conflict, you can contact the National Problem Gambling Helpline at 1-800-GAMBLER (1-800-426-2537). It is free, confidential and open around the clock. You can also use the deposit limits, time-outs and self-exclusion tools that licensed casinos offer. If you write to us about this, we will point you to support services rather than to a casino.
Looking for something else?
If your question is about casinos outside the US, our page on trusted non GamStop casinos for UK players covers a different market with different rules. It is not relevant to US availability. For US questions, send us a note with the details above and we will take it from there.
