In purely luck-based games(like the game in the OP, btw) it doesn't matter whether your emotions envolved, or it's "rational" judgment or a clouded one. It all depends on luck. Period.
A small correction. The above statement is true if you want to earn money through gambling. If your goal is to have fun, then, of course, it is more rational to not bet all your balance at once, but make smaller bets to last longer.
Yeah, it's all just luck, but you can help your luck by playing games that have more probabilities of you winning than others.
It's all math in the end, luck can be helped with it.
Although technically true, in reality this way of thinking doesn't help you much, to be honest. And that is so because when playing a game with 99% RTP instead of 96% RTP you are not guaranteed to win anything. What you are guaranteed it to lose less in the long run. And that "run" is very long. It is so long that it may never happen.
Maybe some gamblers think that choosing games that have a higher chance of winning, such as sports betting, is better, but in reality, if you are not lucky, you will also lose.
Gambling remains a base of luck, that's for sure.[/left]
