There is a chance that the nature of the game has something to do with the gender that plays in that game most. There is no official study for this yet, but I am thinking that we will find more females playing and drawn to luck-based games than skill-based games because of how difficult the process of learning skill-based games may be.
Another observation about luck-based games that a new gambler with an interest in them has to know is that they have the potential to make you, as a gambler, spend more money gambling than skill-based games.
What do you think?
I would definitely include slots and roulette in games based on luck, and I want to say that I have indeed seen many women there. They do not want to bother their heads with the rules and just hope for luck. But in games like poker, I have almost never seen women. After all, poker has many rules and it is often men who sit there. And although there is a luck factor in this type of gambling, men really prefer it.
