Product Description: In Tri-Ball, three teams of 3 to 5 players each, compete against each other simultaneously. The game is at its best when teams are of mixed gender and/or skill-levels. The three differently colored, 20' x 3', volleyball nets extend outward from a common center game standard to three outside standards. Games of three rounds each are generally completed in 12 to 15 minutes. Each round comprises of 12 serves; 4 consecutive serves per team. Points are lost, not won, and one point is lost on every serve. At the end of a game, 36 points are deducted and the team with the most remaining points wins. Rules are almost pure volleyball and are included with each game. Sportime's Recreation model was designed to work with our Big Red Base System and Tall (61"-96") adjustable height aluminum posts. Unique red/yellow/blue 20' net combination attaches, via a common sleeve, to the center post and to the three outside posts via hook and loop straps. Top rope cables keep nets at proper tension. Activity Guide included.
