The only time limit I have is the funds on my deposit. I can spin slots for hours if my deposit allows it. For what reason should I limit myself to this? That's nonsense. If I have money and free time, I play for several hours in a row and at the same time I physically rest from hard work and everyday affairs. It seems to me that this is the best entertainment than getting carried away by something bad. For example, getting together with a company and drinking unlimited amounts of beer.
You have no idea why you should limit your time? Even if you are in your free time like in a whole day due to holiday, will you spend your whole free day to play slots if your balance allow it? Time limit, money limit, and other limit is part of discipline in gambling. If you ignore this and you think that it is nonsense, means that you do not care about yourself.
