Pickleball is a paddle sport for all ages and skill levels that combines elements of badminton, tennis, and table tennis.
It comes with a friendly warning:   The game is easy to learn but don’t be fooled as it can, and most often does, become a quick, fast-paced competitive game for experienced players.
Pickleball is played indoors and outdoors, as a single game with two participants, but most popular with four players, two to a team. 

It is played with paddles and a plastic perforated ball, similar to a wiffle ball on a court size similar to a badminton court, with slight modifications and a net similar to tennis.
Basic rules to the game are simple and easily learned.
