Wallyball (known in some places as reboun volleyball) is a fast-paced sport that was invented by Joe Garcia in 1979 and originally called "ricochet ball." The word "wallyball" is a portmanteau of the words "wall" and "volleyball". Indeed, wallyball is very similar to volleyball. However, wallyball is played indoors, and that is what makes it most popular in the Midwest and Eastern United States, where cold winter weather drives people indoors.
