Pickleball is a paddleball sport (similar to a racket sport) that combines elements of badminton, table tennis, and tennis. Two or four players use solid paddles made of wood or composite materials to hit a perforated polymer ball, much like a wiffle ball, with 26–40 round holes, over a net. The sport shares features of other racket sports: the dimensions and layout of a badminton court, and a net and rules somewhat similar to tennis, with several modifications.
Pickleball was invented in the mid-1960s as a children's backyard game. The spread of the sport is attributed to its popularity within community centers, physical education classes, public parks, private health clubs, YMCA facilities and retirement communities. There are thousands of pickleball tournaments nationwide with two of the largest at the annual – U.S. Pickleball National Championships and U.S. Open Pickleball Championship – as well as numerous international championships.
