Does playing hard to get ACTUALLY work?

My guy friends have told me that if I like a guy and he’s interested in me as well, I have to play hard to get so that I’d know if he’s really interested in me. Is is true that guys get bored whenever girls show interest?

I used to believe that neither men nor women should play mind games.. is it true though? I’ve only been in one relationship and we didn’t date for long. I’m not sure if this is true. All opinions are appreciated! ^_^
