It probably has a better name but this is what everyone I know has called it. It’s a classic with simple rules that everyone can follow. You put a famous or well known persons name on the head of the person next to you and you go round asking 1 yes or no question at a time until someone guessed their person, then theyve won. You can then continue until everyone has guessed theirs correctly. This is a great one when people are feeling less creative/energised so don’t want to do anything like charades. a good end of the night game when wine or time have slowed you all down.
