Wallyball (known in some places as rebound volleyball) is a fast-paced sport that was created by Bill Dejonghe at the Calabasas Racquetball Club (Calabasas, California), in 1979. The game is volleyball played in a racquetball court, where it is legal to hit the ball off of the walls. The idea was an attempt to help bring more business into the club in the summer months. The club pro Joe Garcia then took Wallyball mainstream.
Wallyball is played in a racquetball court which measures 40 feet (12 m) long, 20 feet (6 m) wide and 20 feet (6 m) high. A center line divides the court in half. The net is hung above the center line, traversing the entire width of the court. The net is 3 feet (0.91 m) tall and hung at no more than 8 feet (2.44 m) above the floor for men’s wallyball games and no more than 7 feet 6 inches (2.29 m) above the floor for women. Two service areas are on each side, extending across the entire width of the court and 1 foot from each end wall. The ball is spherical, weighs between 9 and 10 ounces (255 and 283 g), and is 25 to 27 inches (64 to 69 cm) in circumference (the same size as a regular volleyball). The ball is made of rubber.
The word “wallyball” is a portmanteau of the words “wall” and “volleyball”.Wallyball can be played with any number of players from two to four players a side, according to the official rules of the American Wallyball Association. The rules were expanded to include rules for five and six players per side by the Wallyball Information Network (WIN!). WIN! promotes wallyball throughout the world
Wallyball may have roots in an earlier game known as Deckerball, which used similar mechanics and was played as early as 1972. In Kansas, Illinois, a high school physical education teacher and a couple of students sat down to create a game that combined several skills from other games that would be used for indoor play during bad weather situations. By combining handball, tennis, and volleyball, they arrived at the game known as Deckerball (after one of the students involved in its creation, Mark Decker).
