Heebie Jeebies? is a fast flowing party game that provides hours of fun and laughter. Find out what really makes your friends twitch, shiver and cringe. Be warned, however: it's a two-way street, and they will learn the same things about you!

In this game one player starts as the Subject. The other players analyze and guess which one of four cards gives the Subject the Heebie Jeebies. If the players guess correctly they get a point. Then the next person becomes the Subject and a new round begins.

Laughter, shivers, and faces you didn't realize you could make will be followed by more laughter as you play through the cards and explore your friends' psyches as well as your own.
