Pickleball a paddle sport that combines elements of badminton, tennis, and table tennis. Two or four players use solid paddles made of wood or composite materials to hit a perforated polymer ball, similar to a wiffle ball, over a net. The sport shares features of other racquet sports, the dimensions and layout of a badminton court, and a net and rules similar to tennis, with a few modifications. Pickleball was invented in the mid 1960s as a children's backyard pastime but has become popular among adults as well.
