Ping pong rules

Ping pong, or Table Tennis, is played with two or four players using small paddles to hit a lightweight ball back and forth across a net. Players must allow the ball to bounce once on their side before returning it, and the ball must clear the net to count. A point is scored when an opponent fails to return the ball correctly, and games are typically played to 11 or 21 points, with players needing to win by at least two points. Players serve alternately every two points, and each player has two serves in a row.
