Normally it'd be simply say 3 statements about yourself and one has to be true where the other players guess the true statement, but to make it easier to keep going let's say the statements answer a questioned posed by the previous person. The poster following guesses the true statement of the previous poster, gives their 3 statements and poses a question for the next poster.
For instance, if somebody asked "What did you do today?" the statements would be centered around activities you could have done where 1 of the activities will actually be something you did do today.
So starting with a simple one:
What did you have to eat today?
