Lawn bowls is a traditional sport played in many countries, with the oldest existing green dating to 1299. Popular with all types of people, the game involves rolling a series of balls, known as 'bowls', towards a much smaller ball, known as the 'jack'. The purpose of the game is to get your bowls as close as possible to the jack, while also knocking your opponent’s bowls away from that target. Lawn Bowls 2U can explain the game further.
