The object is to make a statement about the next poster that will be answered true or false by that person, with an explanation. ?Then it is their turn to make a statement about the next person below them.
for example, I would say:
The person below me loves Star Wars
the next poster would say:
false. I love Star Trek
the person below me drives a green car.
and so on.
The person below me has heard of this game before.
