In a new study out of the University of Western Sydney, researchers found that pretty much EVERYONE plays hard-to-get when they're trying to attract someone.  It's not even on purpose, it's our biological instinct.  And the three main ways both men and women play hard-to-get are the same. 

The main way that both men and women play hard-to-get is by acting more confident than they really are.  Number two is talking to other people to try to make someone jealous.  And number three is withholding physical contact.

But after those three, men and women are totally different.  For women, the other most common moves are being sarcastic, sounding busy, teasing, flirting with other people, sending calls to voicemail, or turning down dates.

For men, their other most common moves are acting rude, or playing mind games, like saying all the right things, but then not calling.
