If someone rides a lot of bike or plays playstation for a long time, does it have to mean that he is addicted? If someone gambles without money, but has been gambling for too long, is he addicted or does he just like to spend time like that?
In my opinion, spending a lot of time is not addiction, but of course it can be dangerous. Therefore, the best way to do it safely is to take breaks to see if we can control it.
Well, if we are talking about free gambling which doesn't exists, then you are definitely not addicted. "Free" gambling with fun tokens and all is simply gaming, there are a million stuff like that in the mobile gaming world, go open up your android phone and in the google play section you will find probably a million slot games with all kinds of different slots and designs and they are all free, you could still run out of game money and end up spending real life fiat to buy that game money if you want to, but you may prefer not to do that as well which would work.
Long story short it is not gambling, gambling in itself as a word means that you need to risk something for something and if you are not risking anything then it is technically not gambling. Which is why yes ALL gambling is addictive if you are doing it too much and you should avoid it.
