Italian lawn bowling is called Bocce or Boccia and is in the boules family of bowling. This is the art of the underhand toss or roll. It can be a man on man competition or teams of two, three, or four against each other. One team gets two tosses to place the jack on the playing field in the designated area. If they fail, the other team gets the opportunity. The first team to place the jack gets to throw first. The object is to get the bocce call closest to the jack. The teams alternate until all four balls of each team have been tossed on to the playing field. The team with the ball closest to the jack gets to score points. A point is awarded for each ball that is closer the than the closest ball of the opponent. Scoring is usually to 7 or 13. The skill involved is in the throwing or rolling because a good bowler can knock the opposing bocce or the kitty out of scoring range.

The only time, that i can think of, when you spray a bowl in a game of lawn bowls, is when the wood (black bowl) has touched the Jack (white ball)

They spray the black bowl, with a white spray chalk, so that you can see that it hit the Jack. If a bowl has been sprayed with the spray chalk, it means that it is a LIVE BOWL and, even if it is hit out of the rink, it still counts.

The head is area directly around which the "jack" or "kitty" is set.

Lawn bowling (or bowls) as an organized activity has been traced back to the 13th century, with evidence that it may have existed at least a hundred years earlier, in the 12th.

Evidence of a primitive sport that resembles more traditional bowling has been found in the tombs of Egyptian children dating back to at least 3200 B.C., making it about 4,000 years older than lawn bowling - and, at five thousand years old, one of the oldest known sports on the planet still being played today.
