That's how it should be, casinos that allow minors to play there must be subject to sanctions and fines in accordance with what has been recorded in the regulations. But the question is whether these regulations have been implemented properly.? And to what extent can these regulations limit minors from gambling activities.?
The fact is that there are still many casinos operating, both land-based casinos and online casinos, which contain minors. The existing regulations are really not well realized, and even in my country many law enforcement officers are involved in gambling activities, and not infrequently some of them are caught in criminal cases because they cooperate by trying to protect casinos that do not have permits or are illegal.
maybe for physical casinos they prohibit minors from entering seeing the number of people who gamble, I don't know how about physical casinos that are legalized in their country, whether they allow minors to enter or not but I think even though physical casinos in their country are legalized it is impossible for them to allow minors to enter the casino. Unlike online casinos which are currently widespread and easy to access.
for online casinos in my opinion there are very few casinos that implement the KYC system, especially with local casinos in my country, even though my country strictly prohibits gambling but because of the internet which makes it easy for many people to access it, this makes many people do it and does not require further verification such as KYC.
In my opinion with online casinos it seems rare that there are those who prohibit minors from accessing them, because without KYC everyone can do it. It doesn't matter if they are still small if they understand the steps they can do it.
