Hello how may I help you? help me with a game rule I will be happy to assist you do you know how to play tag? Yes. I can help you with Tag how do you know who has won in the end? Tag does not usually have a defined ending. The players decide when to stop playing. but it's a game, there must be a winner Some players consider the person tagged the least as winner. But this is conditional on the players. my kids will not be happy to hear this They can apply the rule of tagged least if it pleases them
