Hello how may I help you? I need to settle an arguement. Can you help with that? I sure can! What's your question? How do I know who wins in a game of tag? In the game of tag, the winner is the person who gets tagged the least amount of times. Not when one of them is a cheater. A friend can keep tally of who gets tagged. That way, cheaters can be spotted. Your making up the rules as you go? I am not. I also want to mention that games of tag don't have a definite ending. Players usually get bored and stop playing. That is what happens yes. Thanks for the tips. No problem!
