At the same time, it is often better not to get involved in gambling with prisoners, since it is better for a newbie to stay away from the card players there. There is so much free time in prison that the card players there are very good at playing cards, and they can cheat, and also their cards are dishonest, with marks.
I think they specifically say first: "let's play for fun?" And then they try to get the newbie excited, after which they will try to win everything he has.
I have never been to prison before, but from the little I have heard and the little we have seen in some movies where prisoners are gambling, some of these are for fun while some of the gambling are amongst group people since prisoners are always divided into groups and each group so have a leader, but most of these gambling is amongst the two or three groups in that prison.
Apart from playing gambling for fun, I know that some prisoners are wealthy, they do always have connection to get money and some goods that prisoners need, so some people are do gamble to get some of these things they will need, and mostly it is between the prisoners because I am not sure if the officials know about that; because they do take it as a fun game even when they come across them playing the games like whots, Ludo, and so on.
