Ordering Ritual
Any procedure used in a multi-player game to determine the (initial) order the players will take turns. Common options are a) physical actons like rolling dice or flipping a coin, rock/paper/scissors, drawing straws, etc. or b) using a fact about each player to order them, like age or first name. There must be some additional rules about how to break ties (if ties are possible) or who gets to perform specific parts of the ritual (like calling the coin flip in sports).
