Jack Meaning in Lawn Bowls

Jack describes the small target ball used as the scoring reference point. Players roll bowls toward the jack during each end. The jack determines which bowls count toward the score. A player places the jack on the green before bowls begin. The jack must travel a valid distance from the mat. Its final position becomes the target for all deliveries. Bowls resting closest to the jack earn points. Players constantly judge distance relative to the jack location. Contact shots sometimes move the jack during an end. This movement changes the scoring area immediately. Teams must adjust tactics after jack movement occurs. Guards may appear to protect the jack from strong strikes. Skips study bowl angles around the jack carefully. During one end the jack sits near the center line. Several bowls roll toward the jack from opposite teams. One bowl stops closest beside the jack position. Officials confirm that bowl currently holds the scoring position. Later deliveries may still change that result. Players therefore watch the jack carefully throughout the end. Accurate placement near the jack often decides scoring outcomes. Understanding the jack helps beginners follow the objective of lawn bowls.
