Spikeball, as seen on Shark Tank, involves 2 on 2 action with a trampoline net in the center of 4 players. The server from 6 ft away will spike the small ball on the trampoline and the other team has up to 3 hits before spiking it back on the trampoline. After the serve, there are no sides with 360 degree play around the trampoline. When the ball hits the edge of the trampoline it is a foul and the other team gets a point. If the ball hits the ground, the team that spiked it gets a point.
