Referred to as Lawn Bowling in North America and Bowls in the UK, Australia and most other countries where it is played. The sport can be played on either flat-surfaced lawns or 'crown greens', where the green has a rise in its middle. The object of Bowls is to get your bowls closest to an object ball, called a Jack. Not only do you have your competitor to deal with but the bowls themselves are not spherical and they are weighted to one side ('biased').
