Hello how may I help you? i have a question about the rules of a game What game? How do you play catch? In catch two (or more) people throw an object (generally a ball) between themselves. The time duration is indeterminate. How do you know who wins the game? There is no winning. Even is someone drops the ball? That might bring some shame on the one who messes up, but still no losing. ok thanks i done have any more questions about catch You are welcome. Have a nice day.
