Hello how may I help you? I want to know how to play tag Okay! First of all, know that the game of tag doesn't have a definite ending. Okay, How do I know when someone has won the game? The game of tag begins when two or more players run around trying to see who touches the other one first. The winner is the person who gets tagged the least. Are there tag backs? Yes. Are you sure? I though there were rules against tagging back? Yes. And the game ends when the players get bored and stop playing. Oh so it game of wills. Whoever keeps playing wins. Quitters lose the game? Yes.
