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.
You are actually right about this. Women generally just love to have fun the easy way. Luck based games involves no stress in playing and the fact that it gives instant results is another thing that makes it addictive not just to women, but to some male gamblers also. Although there are Women who can actually do well with skills based gambling games, the percentage of these Women are too small compared to the other ones who prefer luck based casino games. 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.
When you see the result of the game you just played before you, you will definitely be tempted to play again to either win more money or recover the one you've lost. A gambler who chooses to go for luck base games like slots should learn how to control his emotions. Failure to put his emotions in check, he will keep enriching the casinos at his own detriment.
