Crown green bowls

Crown green bowls, or crown green, is a code of bowls played outdoors on a grass or artificial turf surface known as a bowling green. The name comes from the intentionally convex or uneven nature of the green, which is traditionally formed with a raised centre known as the crown, often as high as 30 centimetres above the edge. The sport is played in the Midlands, Northern England and North Wales. Players roll a set of two bowls from the hand towards a smaller target bowl known as the jack, and the player sending the jack may deliver it wherever they like, so an end can be bowled in any direction, a feature unique to the code. A player scores one point for each bowl closer to the jack than the opponent's bowls, and competitive games between two people are usually played to 21 points, with variations that use more bowls, longer games or teams.
