Ii don't think casino requires love or passion to be involved with it after all it's not considered to be a skilled based game, anyone can decide to just stake some dollars on a dice game or a crash game without having any experience, the game needs no statistics whatsoever and in my opinion women are drawn to these games. Skilled based games on the other hand involves a little bit of drive and passion especially when it comes to soccer betting, in order to predict you must be updated and also patient enough to make your analysis.
I was also thinking that women only like skill-free games until I met a female friend who loves sport betting more than anything else. In fact, she said that slot games are boring to her since she can't spend her time to predict and determine the outcome of the game herself.
She prefers to place bets on games in which her chance of winning is 50% based on her prediction skills and 50% based on her luck rather than only depending on luck for winning.
