Hello how may I help you? Can you help me about game rules? Sure, what is your question? Are you familiar with 'Game of Tag"? Yes. Are there any restrictions on the field of play? There are no restrictions, no. However, it is highly suggested the field does not exceed 3.41 square kilometers and not any smaller than the size of a swimming pool. So we can have as many players we want on the team? Yes. Thanks for the info You are welcome.
