This is a riddle game that I haven’t seen yet, but I haven’t read absolutely every single one of them, so I apologize if it’s a repeat. You have 2-3 people leave the room, and explain the rules to everyone else. Then you call each person in one at a time and tell them that they have to figure out the rules of the game by going around and asking each person questions. They can ask about anything they want, and the more variety the better. The only stipulation is that it has to be a question that most people could answer (for example, “How do you say ‘thank you’ in Romanian?” is probably not a fair question in most youth groups). The first person asked will give the response, “The crazy rainbow.” Each person after that will answer the question that was asked of the person before them. They can answer creatively if they want, but they have to answer from the perspective of the person before them (for example, if the person in the middle asks Jane, “What color are your socks?” and Bob is the one answering, he has to give the color of Jane’s socks, not his own). Here’s an example of what the dialogue will look like:
Q: How tall are you?
A: The crazy rainbow.
Q: What is your favorite color?
A: Oh, about this tall.
Q: What is 2+2?
A: You expect me to pick just one response?
Q: Who’s your favorite singer?
A: More than 4, less than 6.
Q: What month is it?
A: Elton John.
Q: What was the last book you read?
A: It comes in like a lion, goes out like a lamb.
And so on. You generally want to start out giving answers that aren’t extremely direct (like answering the question, “What month is it?” with “It comes in like a lion, goes out like a lamb,” instead of just saying “March”) so they don’t guess immediately. Also, make sure that everyone in the room understands the rules (maybe try a few practice questions first) before you let the people come in. Finally, make sure that the people you call in are people who can laugh at themselves so they won’t get too frustrated. This can be a lot of fun, particularly at a lock-in.
