Although MasterCard is a widely accepted choice for depositing at mobile casinos in the United Kingdom, it is important to note that this credit card brand cannot be used to withdraw winnings. This is due to the fact that MasterCard does not support withdrawals and therefore players are unable to withdraw their winnings in this fashion.
The good news is that most online casinos in the UK offer alternative methods for players to withdraw their winnings. These methods generally include e-wallets such as Skrill, Neteller, and PayPal, as well as bank transfers.
