Does Mastercard work at online casinos?

Yes, Mastercard works at many licensed online casinos, for deposits at least. BetMGM lists it alongside Visa, and New Jersey's rules allow credit and debit cards. The card network does not make the final call, because your bank can still decline a payment. Expect security checks too, as Mastercard monitors gambling merchants' use of them.

Is Mastercard better than Visa at online casinos?

We found no meaningful difference for players. In the sources we read, approval depends on your bank and the casino rather than the network. BetMGM treats both as ordinary card deposits, and its withdrawal time of three to five business days is stated for Visa. See our Visa guide for withdrawal times and credit card rules, which apply in much the same way.

What security checks apply to Mastercard casino payments?

You may be asked to complete an extra check. A notice from the payment processor Checkout.com, which is no longer online, said that in September 2022 Mastercard began monitoring gambling merchants on the use of CVV or 3D Secure in online payments. So you may see a code prompt or a banking app approval. That is normal at a licensed site.

What should you do if your Mastercard is declined?

Work through these in order:

  1. Check that your casino account is verified and your details match your card.
  2. Check that you are in a licensed state, because location checks can stop a session.
  3. Ask your bank whether it allows online gaming payments on that card.
  4. Try another allowed method, such as a bank transfer or a prepaid account.
  5. If a licensed casino has charged you wrongly, use its complaint process.

What is the Play+ Mastercard?

The Play+ Mastercard is a pre-loaded card for gaming and other spending from Sightline Payments, announced with Mastercard on October 6, 2021. It works differently from a bank-issued Mastercard, because you spend only what you load. See our guide to Play+.

Should a Mastercard work at an offshore casino?

Do not assume so, and be careful if it does. Regulation GG requires card systems and banks to have policies for blocking unlawful internet gambling payments, according to Nelson Mullins. And offshore casinos have no US state regulator to help if a charge or a withdrawal goes wrong.

What are the rules in your state?

Each state sets its own online casino rules. Pick a state to see its status, its regulator and the date we last checked it.
