Objective: Have the most x’s by the end Every Q you answer correctly, you can take 2 X’s away from a team or add 2 to your team. Cannot exceed the 10X’s you start with or dip into negatives. Every Q you get wrong, you lose an X. We continue until someone answers it correctly or we return to the first team.
