Abstract
An enclosed or open playing court, of generally rectangular shape, has two vertical end walls and two vertical side walls with four traps or alcoves spaced along the side walls. The court is bounded by a floor below, and optionally a ceiling above. The vertical end walls at each end of the court are the scoring walls. Players typically stand at each end of the court and face each other. A resilient rubber ball is caught and thrown by hand. The play consists of throwing the ball towards the opponent's scoring wall. The ball must bounce twice on the floor within a designated area, before being caught by the other player, or striking the opponent's scoring wall at a minimum height above the floor. In normal play, after the ball is caught by the other player, it is returned by throwing the ball towards the scoring wall defended by first player. To score a point, the ball must pass the other player and hit the back wall.
