Stop play for confusion, inability to remain awake, repeated vomiting, seizure, slow or irregular breathing, pale or bluish skin, or loss of consciousness. Seek emergency medical help immediately.

The playing area should provide at least an arm's length of clear space behind each team where practical. Spectators, bags, cords, chairs, and breakable objects must be kept away from players and from places where missed cups are likely to fall.

Cups should be clean, undamaged, and dry on the outside before the round begins. Cracked glass, ceramic vessels, metal cups with sharp edges, and containers that could shatter or injure a player are unsuitable.

A cup that lands on the floor, on another cup, in a player's hand, or upright does not complete the leg. A cup hanging over the edge is valid only if it has stopped moving, is inverted, and remains supported without being held.
