That is why me, I see gambling as an addiction game. When someone place bet and probably wins once, he will be determining to win more but as he continues to play the more he loses. He would even finish what he has won and he would also enter extra cash to lose more. The lose more than the way they win. And the funniest part of it is that they would not stop playing even upon the numerous losses compared to the wins.
I don't know why gamblers can't go home after when they win, they must stay back and play some games first before going. Gambling is a game of addiction. That is how I see it.
You may have assumed wrong if you take gambling in it entirely as an addiction, because I have seen a gambler who have master the game to the point that he knows when to walk away from the game not matter his position either winning or losing he will simply walk away when he reached his limit.
I believe everything is all about self control so not all gamblers are addicted, I have played some few games even today I played some but I can't say I am an addicted to it.
