Licence on the regulator's register
A logo in the footer proves nothing. The licence number and company name must appear on the regulator's own register, with the same domain.
Copy the licence number from the casino's footer and search it on the regulator's public register. Some regulators publish no searchable register; then ask support for the certificate.
