Hi, Narasimha
In One min 30 members cant play any game. If it is one min each I can suggest U a game. The game is a kind of dumb charades.
--Write All the participants name on chits.
--Collect them all and Let all the participants to take one chit each.
--The name which a participant gets shouldn't be disclosed to any one.
--So, One by one every one should come and by acting they have to try to make the other
participants guess the name.
--Each participant can act "1" min only.
It will be very funny and at the same time you all will be able to know your Friends much more than now... :)
Hope it may help you to make your day a memorable one. Have Nice time
By the way Name of the game is "Hidden Friend"
