Credit cards have been banned at all UK Gambling Commission-licensed casinos since April 2020 to protect players from gambling with borrowed money, but UK players can still legally use Visa and Mastercard at offshore casinos licensed by international authorities like Curaçao, Malta, and Anjouan. These internationally-licensed platforms—including Velobet, Fortunica, Cosmobet, 1Red, and Magic Win—offer UK players significantly higher bonuses (up to 450%), faster withdrawals, fewer deposit restrictions, and full access to credit card payments while operating outside GamStop and UKGC jurisdiction.
