Hello how may I help you? Are there any rules or restrictions in tag about field of play? It is generally accepted that the field of play does not exceed 3.41 square kilometers and not get any smaller than the size of an olympic swimming pool (1250 square meters). What happens if someone exits the field of play? They get disqualified. Are there any other major rules to the game? The only other major rule is that you must touch the opposing player with your whole hand. Is there a limit as to how many times a person can be "it"? No limit. Thanks! You're welcome!
