For players in Great Britain: the card type matters. Mastercard is a payment brand; a logo does not establish whether a particular card is debit, credit or prepaid.
Credit cards and UK online casinos
Gambling businesses serving Great Britain must not accept credit-card payments for online casino gambling. This also applies when credit-card funds are routed through an e-wallet. The earlier version of this page described credit-card funding; that advice has been removed.
Debit-card availability
A debit card may be offered in a casino’s cashier, subject to the operator, issuing bank and account checks. Use the current cashier and bank terms to confirm availability. Do not treat debit-card access as a reason to spend beyond an affordable limit.
Deposits, withdrawals and costs
Check the operator’s cashier for accepted methods, transaction limits, fees and processing times. Acceptance for deposits does not establish that withdrawals use the same method. A payment can be declined or delayed; no card network guarantees that a casino payment will succeed.
Read the account and promotional terms before depositing. Do not assume that a payment method qualifies for a bonus. Compare our UK casino reviews and payment methods directory.
