Does the "make him jealous" trick really work?

I've been browsing and saw some questions like: how can I get him back? How can I make him realize he's still in love with me? ... Almost every time someone answers: make him jealous. Pretend you're with another guy, kiss someone, ...

So when you fancy a guy, or a guy just broke up with a girl and she wants him back. Does making him jealous actually work?

After reading some answers I'm glad I never tried to pull the jealousycard on an ex boyfriend ^^
