Hello how may I help you? I need some info, can you help? I can give you information about Game rules How about tag? Do you know that? Yes I have the official tag rulebook. What kind of field do we need to play on? Are you interested in the size of the field? Sure! The field of play should not exceed 3.41 square kilometres and not get any smaller than the size of an Olympic swimming pool, or 1250 square metres. Wow, that's very specific! That is what is generally suggested. It is not an official rule.
