Gambling in prison is more of a kind of entertainment for them. Since no one would gamble for money, prisoners would only gamble for what’s only available to them like their personal thing, foods or anything that can be gamble and would bring excitement to both of the players.

However, gambling with money is strictly prohibited so their kind of gambling is different from gambling in the real casino. But even though, if their gambling activities suddenly lead to a fight and mess up with other prisoners, still it will never be allowed inside the jail.
