The main advantage of such sites is that they have passed a number of checks before they get official permission. Obtaining a license is a time-consuming and expensive procedure. Fraudsters cannot provide the licensor with documents, reports and evidence that the software used is original. Authoritative regulators give the green light only to online casinos with licensed slot machines. By registering on such a site, the user receives guarantees of protection against playing on a scripted site with pirated software.
