So basically in this game you just have to give the person below you a riddle.
Example,
Ralph: I spy with my little eye, something yellow, roundI and eats dots!
Venelope: Pac-man!
(This is from a movie and I’m just quoting it. You don’t have to start with “I spy with my little eye”, just to be clear)
For the next person, riddle me this…

Because it has two banks?
It was never scared but became petrified, it can’t make a bird but can make a bat, it can’t live in a house but would die to have one. What is it?

A boy was at a carnival and went to a booth where a man said to the boy, “If I write your exact weight on this piece of paper then you have to give me $50, but if I cannot, I will pay you $50.” The boy looked around and saw no scale so he agrees, thinking no matter what the carny writes he’ll just say he weighs more or less. In the end the boy ended up paying the man $50. How did the man win the bet?
