Trac Ball (or Trac-Ball, or Tracball) is typically a game of catch played by two or more people wherein both participants wield an oversized glove/racquet/basket, passing a ball back and forth. The racquet is similar in appearance and function to a jai alai basket. Trac Ball is also utilized in a game called whirlyball. Whirlyball is a game played on bumper cars where two teams using track balls attempt to score goals against one another by throwing the Trac Ball into the opposing team's elevated net.
