Bowls is a sport in which the goal is to roll slightly asymmetric balls, called bowls, closest to a smaller?normally white?bowl called the "jack" or "kitty".
Bowls, either flat- or crown-green, is usually played outdoors, on grass and synthetic surfaces. Flat-green bowls can also be played indoors on synthetic surfaces. Both variants are collectively known as "lawn bowls".
Bowls is popular in the United Kingdom, Australia, New Zealand, Canada, South Africa and parts of the United States. It is also gaining momentum in Japan. Because of its competitiveness, skill and the fact that it is a non-contact sport, the game suits people from teen years through to their nineties. However, there is a considerable professional competition with many younger men and women playing. Since the early 2000s, the sport has developed in Denmark as well[citation needed]. The World Championships held in the UK annually is a ?100,000 competition and is watched by 3 million viewers via BBC TV
