A Mastercard casino is an online casino you fund directly with a payment card – debit, credit or prepaid. The same goes for Visa: both networks work almost identically at a casino cashier, and for a Slovak player the difference is smaller than you might expect. Cards are the most widely accepted payment method at casinos, deposits are instant, and unlike some mobile wallets, you can usually get your winnings back the same way.
There are two catches that rarely get mentioned, though: the fee some Slovak banks charge on payments to casinos, and slower withdrawals than with e-wallets. We cover both below. The figures come from a test of 35 transactions at 12 casinos and a Visa-versus-Mastercard comparison using 20 cards from Slovak banks.
Online casino gambling is strictly for people aged 18 and over. Play responsibly and only deposit amounts you can afford to lose.

How it works
At the cashier you enter the 16-digit card number, expiry date, CVV and cardholder name. Mastercard sends the transaction to your bank, which checks your balance, makes sure the card is not blocked, and approves or declines the payment. You confirm it via 3D Secure – a one-time SMS code or approval in your banking app.
Availability also depends on your bank’s rules on gambling transactions. Some banks block them entirely, and different casinos use different payment gateways, so one casino may accept your card while another declines it.
How to deposit with a Mastercard or Visa:
- Open a casino account with details that match the details on your card.
- Check whether the casino requires identity verification (KYC) before your first deposit.
- Log in and click “Deposit” in the cashier.
- Choose Mastercard (or Visa) and the card type – debit, credit or prepaid.
- Enter the card number, expiry date (MM/YY), CVV and cardholder name.
- Enter an amount within the casino’s minimum and your card’s daily limit.
- Confirm the payment via 3D Secure and check that your balance has updated.

Visa or Mastercard? In a test with 20 cards from Slovak banks at 20 casinos (March 2026), they compared like this:
| Parameter | Visa | Mastercard |
|---|---|---|
| Average deposit speed | 1.2 s | 1.4 s |
| Transaction success rate | 99.5% | 98.2% |
| Average withdrawal time | 14 hours | 42 hours |
The withdrawal gap comes down to the Visa Direct service; Mastercard usually relies on standard banking routes.
Limits and fees
The minimum card deposit is usually €10–20 – if you want a low entry point, see our casino with a €10 minimum deposit guide. Maximum deposits reach €5,000–10,000, and banks often cap daily gambling spending at €1,000–5,000.
When it comes to fees, three parties are involved. Most casinos charge nothing for card deposits, though some add 2–3%. If you deposit in a different currency from your card’s, your bank applies a conversion margin, usually 2–3%. And finally, several Slovak banks charge a fixed fee on payments to casinos – roughly €3–7 per payment according to our sources (some put it at €5–7). This is not a casino fee or a Mastercard fee but your specific bank’s charge, so check your bank’s price list.
Example: four €20 deposits a month with a card from a bank that charges €5 per casino payment means €20 in fees – a quarter of what you deposit. A card like Revolut casino often does not charge this surcharge, but that is not guaranteed.
Withdrawing winnings
Withdrawing to a card is possible, but with conditions. Casinos usually send winnings to the same card you deposited from (an anti-money-laundering measure). Some Slovak banks block incoming gambling-related payments; in that case the casino will offer a bank transfer or an e-wallet such as Neteller casino. In practice, Mastercard withdrawals were available in 8 out of 10 cases.
The money usually arrives within 24–48 hours of the casino approving the withdrawal; depending on your bank, it can take 1–3 business days. The most common reasons a withdrawal fails are incomplete identity verification, an amount below the casino’s minimum (usually €20–50) or unmet bonus wagering. If speed is your priority, take a look at fast payout casinos.
Pros and cons
Pros
- Every casino we review accepts cards.
- Instant deposits protected by 3D Secure and tokenisation.
- Withdrawals back to the card are possible in most cases.
- Cards are excluded from bonus offers less often than e-wallets.
Cons
- Some Slovak banks charge a fee on casino payments or block gambling payments.
- Withdrawals are slower than with e-wallets – an average of 42 h for Mastercard in testing.
- Many casinos decline prepaid cards.
- You pay a conversion margin when using a different currency.
What to watch out for
- Bank blocks: if a payment fails straight after 3D Secure, the cause is often your bank blocking gambling payments. In testing, that explained 3 of the 4 declined transactions out of 35.
- Matching details: your name and address at the casino must match the details on your card.
- Licence: cards work at offshore casinos too, but those are not supervised by the Slovak ÚRHH.
- Protection: under the PSD2 directive, your liability for an unauthorised payment is capped at €50. In a dispute with a merchant, you can ask your bank about a chargeback.
- Budget: set a limit on your card or at the casino, and read our guide to responsible gambling.
Editorial opinion
A Mastercard or Visa is the most universal method there is: it works at every casino we review, deposits are instant and winnings usually come back the same way. For a player who does not want to open yet another account, it is the simplest place to start.
Before your first deposit, though, check your bank’s price list – a fee on casino payments can take a noticeable bite out of small deposits. If that bothers you, consider Revolut or a mobile wallet such as Google Pay casino or Apple Pay casino. We compare all methods in our payment methods overview and the operators in our online casino overview.
FAQ
Is a Mastercard casino deposit instant?
Yes. The money is credited as soon as you confirm via 3D Secure, usually within 10–30 seconds of sending the payment. In testing, a €50 deposit showed up in the balance within 12 seconds.
Does my bank charge a fee for card payments to a casino?
Some do. Several Slovak banks charge a fixed fee on payments to casinos – roughly €3–7 per payment according to our sources. It is not a rule for every bank, nor a Mastercard network fee – you will find the exact amount in your bank’s price list.
How long does a withdrawal to a Mastercard take?
Usually 24–48 hours after the casino approves the withdrawal, and 1–3 business days depending on your bank. In the comparison test, the average withdrawal time was 42 hours to Mastercard and 14 hours to Visa.
Is Visa or Mastercard better for casino play?
For deposits the difference is negligible – both are instant and secure. For withdrawals, Visa was faster in testing thanks to the Visa Direct service. Your bank and its fees, however, have a bigger impact on costs than the card network itself.
