A taut Hula Hoop-sized net is placed at ankle level between a pair of two-player teams. You smack the palm-sized ball down on the net so it ricochets up at your opponents. They have up to three hits between them (just like volleyball) to control it and bounce it back to you. When they miss, you score. First team to 21 wins. Great for athletes cross training for Lacrosse, Tennis, Ultimate Frisbee, and for athletes who do Crossfit. Spikeball is a great outdoor, indoor, backyard, camping, beach game for adults, and kids.3 Ball Set, Drawstring Bag, And Rule Book.
