Sticky Notes: When a player gets a rule, write it on a sticky note and put it on their chest. A dedicated person can do this, or players can write their own.
A Referee: To keep score and call out players who don't follow their rules.
How to Score
Completing a PROMPT successfully earns you +2 points AND you get to shred one of your active rules. Failing a prompt costs you -2 points.
Players can also earn a point by calling out another player who isn't following one of their rules. They also get to give that player one of their own rules.
