My god man, you are really displaying some ignorance. Of course women are capable of being as good at pinball as men. Probably better. It’s more that it’s a male dominated hobby for many reasons Men are closer to children and still play with toys like pinball machines. It’s also that pinball machines are designed by men and so are designed to appeal to men. Have you ever noticed that 90% of pinball machines ever made are covered in drawings of boobies, butts and crotches? Also a great deal of women who have shown and interest or talent in pinball were probably marginalized or harassed or otherwise pushed out of the hobby by the male culture.
