Game Rules

Each group will get the chance to answer each question. You don’t need to “buzz in first.”

Group members must come to a consensus before giving an answer.

Answers must be written down. A different person in the group should read the answer each round.

Groups will receive points for correct answers and up to 400 points for Participation.

You may get partial credit on some answers. The winning group will receive either points or candy

– each person can choose for themselves..
