A footbag is a small bean bag or sand bag used as a ball in a number of sports and games. It is typically controlled by the feet, but in some sports every part of the body except the hands and arms may be used. The term footbag is also the generic name for the sports which use the footbag. The main varieties are footbag freestyle, footbag net, and circle kick. Both the footbag and the sports that use it are sometimes referred to as hacky sack, hacky-sack, hackysack, or hackey sack. The same game has also been practiced with a toy called a Koosh Ball.
Footbag, as an organised sport, is governed by the International Footbag Players Association, a non-profit organisation. The IFPA hosts a non-commercial, non-profit website at http://www.footbag.org, which details the rules of professional play, schedule of events, and results of past events.
