psychologist!!!!!!!!!!!!!!!!!!!!!!!!!!!!
basically u set a rule(if smth smth, then do smth smth) that only you know of. Then u ask the rest of your friends to sit together and ask you questions. Any questions which can be answered with yes or no. Then they have to figure out the rule based on your reactions to the answers.
When a person wants to guess, you have to bring him/her aside to confirm the answer. If he/she got it right, he/she joins you to be asked. If he/she doesnt get it, stay in the group. Usually those who got it right will sit in a circle and the others will be grouped in the middle of the circle.
You should play it on the first day and then surely some of them wont be able to guess the rule. Play it for a few more nights and on the last night. Keep playing till they finally get it.
The fun part is that you can ask any questions and the answering person has to answer as honestly as possible. For me, the rule set was if a person's answer to a question is no, and the person beside has a yes to the answer, then he/she will shout psychologist and everyone sitting around the circle will change seats randomly.
p/s: I asked them whether they had hair around their assholes. Some girl shouted psychologist
