Pickleball is one of the fastest growing sports in America that can be played by any age. It is played by either 2 or 4 players. Pickleball is a sport that combines tennis, badminton and ping-pong, and is played on a badminton-sized court with a net. Players use paddles that are slightly bigger than a ping-pong paddle and a ball with holes, resembling a whiffle ball.
