A "Z Games" Sampler
Strack - the name fuses "string" and "sack." A plastic sack filled with dry dog food or congealed Jell-O is tied with a string and swung around near the ground by a player in the middle. Players on the outside must jump over the sack. The last player to get hit is the winner and becomes the new "Swinger."
Stairball - A game similar to one-wall handball. Two players take turns hitting a ball up a staircase. Points are awarded when a player's opponent fails to return the ball as it bounces down the stairs.
Boccer - A cross between basketball and soccer in which a soccer ball is maneuvered by a player's feet when outside the key. Only players inside the key may pick up the ball and shoot it.
