How to Play: Hackball
What you need: You need a hacky sack, a four square court, and four players.
How to play: On the concrete, chalk or paint four squares on the ground. All squares touch each other, making one larger square. Each player stands in a square. The players will toss the hack sack back and forth to each other. The squares have a rank order, from one to four -- four is the highest. When players are out of the game, they must go back to square one, and all other players move up a square.
The rules: When volleyed from square to square, the hacky sack must not touch the ground. It must stay in the air. If a player fails to hit the hacky sack or if it lands out of bounds after he hits it, that player is out of the game. If a player spikes the hacky sack, making it impossible for another player to hit it, that player is out. Players can hit the hacky sack with any part of their body, as long as it stays off the ground.
How to win: The player in square four at the end of the game is the winner.
What else you need to know: The squares in this court can be smaller than the traditional four square court. Three feet by three feet is a good size for each square.
