You can use your credit card for gambling at a casino in most of the world’s countries. In countries like the United Kingdom, using credit cards for gambling is not allowed from 2020. If you are unsure, please check with your operator if your credit card is allowed in your country. In general this is not a preferred method or way to handle these transactions, and that’s ultimately a good thing. It’s not advisable to rely on this method, given other more efficient options that are less likely to compromise your finances.
