They are entertaining at the beginning but soon they become your worst nightmare and I never recommend anyone to play slots,in poker and sport betting you have somewhat much more control while in slot machines you just hit a spin button throwing yourself into total randomness which is programmed to make you lose money in the long run.
I wouldn't go so far to say that no one should play slots. Slots should be forbidden for minors, that's for sure. But for adults it's a good thing in many ways. I myself still play slots, but not more than 30-40 minutes per day, and not every day, of course.
That's a little harsh not to recommend playing slots; I believe he had gambling issues. To begin with, you already know that there is a 60% chance that you will lose your money and a 40% chance that you will profit when you gamble. We gamble to have fun; we occasionally win but frequently lose; we play for the happiness it brings us. Slots have been in the gambling world since then, and while it is already programmed to have a slight chance of winning, if luck strikes you, it has the possibility that you can win big. Until now, a lot of people have played slots, and others have tried to have a strategy to win them.
I don't know, mate. Why are those chances?
If you simply mean, we are more likely to lose, I agree with you, but if we are talking about some real percentages of winning/losing when playuing slots, it is more like 52% to 48%, not 60% to 40%, imo. As for your saying "we play for the happiness it brings us", I totally agree with you. There are not that many things from which you can get that "happy hormone" so easily. Only this dopamine mining have to be approached wisely. You should not lose a lot of your money on it, lest you regret the whole thing lately.
