This team sport can be played indoors or outdoors and takes place on a badminton court using a perforated plastic baseball (similar to a wiffle ball) and small paddles. The pickleball net is lowered to 34 inches for game play, and each game is played to a score of 11 points.

Word History
Etymology
pickle entry 1 + ball entry 1
Note: The game was invented in the summer of 1965 by a group of neighbors on Bainbridge Island, Washington, including then state representative Joel Prichard (1925-97), Bill Bell, and Barney McCallum. According to one account, pickle was suggested by pickle boat, a boat in crew rowing made up of rowers not chosen by other teams (as pickleball was amalgamated from features of other paddle sports). Another account claims that pickle was inspired by a dog named Pickles owned by one of the neighbors (though it is also claimed that this dog was named after the sport). (See, among other sources, the website of the USA Pickleball Association, and www.pickleballportal.com.)
