This is Crown Green Bowling. Teams of 10 or 12 usually play each other in proper matches: one from each team makes up a pair. Each player has 2 bowls (woods) and the objective is for you to get yours closest to the jack (a small ball). Points are awarded, and the first to get to 21 wins. Team scores are added up at the end.
You won’t need anything except flat shoes. Lots of help is available. For more information please use the Contact Link.
