Live casinos are usually exclusive to specific countries or regions. However, a majority of them serve a global clientele. Each casino usually has a list of all countries from which players are allowed. One of the main reasons for limitation is usually licensing. In most cases, if a live casino is not licensed to operate in a given country, then it might not offer its services in the country.
Another top reason is customer service. Most online casinos usually operate in countries where they can provide customer support effectively. The languages spoken in a country are usually a common limiting factor regarding customer service. Live games also typically have interactive hosts, which might be a challenge when there is a language barrier.
