Greediness is the real reason why gambling is addictive. When you play dice and you won a lot with your starting minimum amount then that will crave you to earn more and even higher. But of course if there are times that we are lucky, times of unluckiness will come also and when it happens to us, we want to take cover our losses.
Not all all perhaps, that greediness is the main reason. As I observed and noticed when it comes to a gambling topic many says it is bad, that depend on individuals of how are he/she gonna interpret it. but whatever games in the gambling site whether it is poker, dice, spinning etc. those games are the tools of casino owner to input an addiction to the gamblers which is there customer in the gambling sites. Once the game fulfill their satisfaction there is repetition will be happen until it become a habit for them. That in the last they are addicted in the games.
