What I have seen is that in our country, four people together create a gambling party and four people start gambling there (especially in rural areas). I have seen them gamble for a long time, if necessary, they spend the whole night in that party. In the meantime, if anyone wants to come out, they stop him from coming out, but there is no threat of beating. The threat of beating is given only to those people who are completely harmless. Moreover, those who are a little influential or powerful are not threatened with beating. Maybe they say that they will not let him gamble with them again in the future. That's all. They will not beat him and will not threaten him.
I am wondering how it is almost the same as my country. I'm not sure if it's the same, but I don't really want to reveal it. I am not aware of any casino houses in my country, and if there were any, that would be illegal too. Because gambling isn't legal here, and for offline gambling, people have to choose some different way. As you said, people choose card play as a gamble, but it's in rural areas too. Because if legal authority knows about the gambling, then gamblers will have problems. So gambling in my country mostly happens within a circle; there is not a wide range of offline gambling here.
Yes, I am talking about the card game where four people form a team. As far as I have seen, I have seen such a game so far, but (in rural areas). And I do not know whether such a card game is played in the city. Although such teams are formed in rural areas, they form teams very secretly and gamble there. One of the reasons for forming teams secretly is that gambling is not legal in my country. Since gambling is not legal in my country, people are very afraid and form teams secretly to gamble. Still, sometimes it is seen that administrative people come there and create obstacles and even arrest one or two from here.
