John Glenn Djokovic Ladder is a tennis ladder in South Gate, California.
It's like handball tennis. You must hit the ball into your side of the court first before the ball goes over the net. ... 11 points wins a set (win by 2). First to win 2 sets is the winner.
A simple challenge ladder. You can challenge 3 spaces above you. If you win the challenge, you switch places with the other player. Have fun.
