I am sure there are laws that regulate the establishment of casinos in any country, therefore it is not necessary to just build a casino just anywhere. If a casino is built in a place that is located close to educational facilities, hospitals, etc., it will be subject to sanctions or even closed. I mean that a land-based casino will set up a casino by submitting a letter to the government (if in that country casinos are legalized). Of course there are several requirements that must be met in order to operate properly according to applicable regulations. For example the location is more than 10 kilometers from schools and hospitals, the environment is a place where there is a lot of tourist interaction, etc.
