This document outlines the rules for a probability game with three rounds. It will be played in groups, which will be determined by each person naming someone they do not want in their group. The person with the most votes can then select their group members. The first round involves rapid-fire probability questions for each group to answer within 10 seconds per question. The second round includes two longer subjective probability questions for each group with 5 minutes to answer each. The third round allows each group to select a probability question from a set, scoring 3 points for a correct answer. They can exchange their question for another at the cost of 1 point. Collaboration between groups is permitted in the second round for additional bonus points.
