Wallyball is a game played on a four-walled raquetball court with rules similar to volleyball, and with a ball the same size as but harder than a volleyball. The ball is allowed to bounce once against the ceiling or one of the walls before being returned over the net which adds a level of difficulty and fun.
This is a popular game in the midwest and east coast and we are trying bring it here to the Bay Area. Currently finding a facility that will allow us to host this and buying the equipment. If anyone knows of any raquetball courts let me know. The net will be attached the the walls via suction cups, so not damage to the walls will be made
