Have you seen a little black and yellow trampoline game all over but still have no clue why groups of people are spiking a ball down into it? Finally, you'll get some answers. Spikeball is a new sport that's sweeping the nation. It's commonly referred to as the love child between volleyball and four-square. It is played 2 vs 2, with a taut hula hoop sized Spike ball net placed between the teams. A player starts a point by serving the ball down on the net, so it ricochets up at his opponents. They have up to three hits between them (just like volleyball) to control the ball and bounce it back off the net. Teams will play a 10-game season followed b a single elimination tournament. T-shirts awarded to first place.
