HACKBALL this is essentially like 4 square. the main difference is that you use a hacky sack for
the ball. it makes for a very portable 4 square game. the necessary rule changes then include:
2)one must never hit the hackball in a downward fashion ('spiking' the ball). this would be a breach in player's etiquette, and the offender would be punished by loss-of-square privileges.
3)in further explanation of rule change number two, the hackball is required to rise a considerable distance from the attacker's hand in order to be considered a legitimate 'volley' (this prevents one from 'letting' the hackball down in another's square).
4)a volley may be instigated by any part of the body. the more obscure and creative the hit the more respect one earns.
5)the squares must be much smaller than traditional. we found that the smaller the square, the closer and more
action-packed the play. our preference was about 3' x 3'.
