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”.
