This research is some worth limited to slots bases of addiction and I think that shouldn't be. It pretty much applies to every game that is gambled on, be it Casino games or spots betting. The definitive nature of it is based on individual understanding, acceptance and liking towards a particular game to gamble upon. This is exactly how you get to build an addiction especially when you feel you know the game too well already and associate your trier frequencies to a win.
Slots and many other Casino games might seem this way compared to sportsbetting due to, the timing and how many go you could go in hours over the games you are particulate about bit the same doenst go for sportsbetging and I say this without considering the virtual reality aspect of it. So yeah, it's pretty much every game in the gambling industry.
The author or the researcher of this article may be a fan of slot and is having a a sign of being addicted with it. They did not know that other people does not play slot but are addicted with other games, most especially in sportsbetting.
If you know the game the most, you will have a good time playing with it and it can make you addicted but there are some that can get addicted to a game that is still new to them because they get curious with it and they also experience a fun. It's normal to get addicted if we are exposed to the game for a long hours but for me to resist it, I just think about my other expenses. It is hard but it is working well on me.
