The Rules of Hacky Sack
No Hands (except when serving), No Arms - Shoulders are technically allowed and are widely accepted among the average hack circle.
Always serve the bag to someone else, unless of course you are alone. Footbag is traditionally a game of courtesy, hence "The Courtesy Toss": a light lob usually toward the receivers knee.
Don't bogart that bag. - Don't always hog it 'till you drop it because that sucks for everybody else. Being able to pass well is important to almost all footbag games.
Don't say "sorry". Everyone makes mistakes, especially when learning, so sorries are unneccissary.
Try not to give knee passes Passes from the knee tend to go strait to the ground.
