A game of lawn bowling begins when one player rolls a metal jack or small white ball called a kitty onto the grass rink. The kitty is the target that the players will try to hit with their lawn bowls or balls. Once the kitty has been thrown and hits the grass, it is lined up with the center of the rink. Now the real fun begins! Players from each team take turns throwing their lawn bowls towards the kitty. Each lawn bowl is a colored, baseball-sized ball made of wood wrapped in leather, pure wood, heavy plastic or metal. ______________ each team takes all of their turns, points are given to the team whose bowls are closest to the kitty. The teams keep playing rounds like this until one team earns 21 points. Once your team has 21 points they win the game.
