Hello how may I help you? do you know rules of games? Yes, I can help you with that. do you know about the game tag? Yes, I have information for the game tag. how to tell who's won the game? There is no definite rule for who wins in a game of tag. Players usually get bored and stop playing. i don't think that is true, are you sure? Yes. But winners can alternatively be decided by who is the person who gets tagged the least. that sounds incorrect. are there other ways to know? Unfortunately, that is all that I have for picking a winner for the game of tag.
