Ok so here is a game that I didn't see a post for. Not to say there isnt one already out there, but I couldnt find it. 

It is a winking killer game whereby students take roles such as killer, police, citizen, double agent.  I use a deck of cards but you can assign the roles, but it should be a secret.

Killers kill people, police catch killers, citizens do what they have to to stay alive, double agents are the chaos factor.

Have fun and feel free to change it and repost it. I put this together really quick FYI!!

If you wanted a version of the game with more movement, Ritzckrakr, you could try "Vampire" or "Secret Handshake". In Vampire, participants wander around the game space and the killer murders by barring his teeth at another person.  In Secret Handshake the participants will shake hands with each other, and the killer murders by using a special shake (usually something like scratching his victim's hand, but you could make it anything).
