For me playing in the demo version is quite fun for the beginning of the game but the fun only lasts a few minutes and after that it's boring, on the other hand of course as I said before friends that there are no real wins and real losses in free mode, all that is just a picture that we can see and without us feeling the results if we win so that's what makes most gamblers not put any interest there, some may switch and play in free mode when they run out of money but most people prefer to find money or loans to return to playing in real mode. Agree with you that most gamblers may make gambling as a place of income even though the reality is far from what they always think and expect, the fact is that it is very difficult to get a winning streak there, simply put you will experience 1 win at the expense of 3 - 5 defeats, that's a fact.
I think Demo accounts are fine to learn the games and see how the casino works, but it's not a substitute for gambling. There might be a few people that look at a demo account as if it was real money and will gamble carefully, the majority of users however will just bet all their money very quickly to achieve the highest possible return. Which is also why this is not a good alternative for someone struggling with gambling addiction. You forget to look at your risk, because you can just top of your balance again once you go broke.
Yes that's right, demo accounts are provided by casinos only for those who want to learn some games that they don't understand, adapt to new games until they really can and after that switch to real accounts, I think this demo mode is only intended to learn new games because it is not uncommon for us to see some gamblers who complain when they try new games on real accounts and end up making mistakes because of their lack of understanding of how to play the new game so casinos make demo accounts to be used as a learning place for those of you who want to learn some new games there.
And for the problem of overcoming gambling addiction, obviously what you said makes sense that a demo account is not a place to overcome gambling addiction, I understand that you can play there without having the risk of losing real money but we must understand that it is not uncommon for someone who after playing on a demo account then they switch to a real account because they see a very good game spin on a demo account so they feel tempted to try it on a real account when in fact the results will clearly not be the same. So if you really want to quit gambling then obviously don't touch anything that could potentially influence you to go back and get involved in gambling.
