Being monotonous is not such a bad thing. If you are only gambling to look for a rush then you might be an addict. What is the point of having excitement for a short while if it ends up negatively affecting your mental health? Sometimes I am tempted to try a new game or a new casino but I know it would end up costing me money I can't afford to lose if I jump into the new shiny thing without any restraint.
It is true but i think his eagerness to gamble is his habit that his looking for some ways just to gamble, and trying all those kinds of games without enough knowledge just to have some fun, I think it is much better if he switch into sports betting than this it is more entertainment, In gambling of course there's a 50/50 chance that you win it is all by luck when playing games but if you knew what you're doing then your always save your investment after making some profit.
