I have never seen gambling as fun.
It is either a addictive behavior or an obsession to an individual and it is not a fun thing to be a part of.

Thats because they cant control themselves. Dont play gambling very often because thats the cause of addiction. Set an amount that enough for you to lose. Dont get frustrated when you loss. Ofcourse you will get frustrated but not in the sense that you will be gamble more to take back what you loss. That mentality could lead you to misery that youbdont want to be.
