Hello how may I help you? I need to clarify some rules when it comes to a game Okay which game? How do I play "catch"? Catch is played by two players. They throw an object back and forth. This object is usually a ball. The game goes on for an indeterminate amount of time Who wins the game? Whoever can keep the ball in motion the longest wins. The player that drops the ball loses. Oh, ok thanks! And how long should we play for? You can play for as long as you desire. Most games last 15 minutes or less. Thats all I needed thanks! No problem.
