How a lawn bowls game works

1. Players take turns to roll bowls along a flat green towards a small ball, the jack, which is rolled out first at the start of each end.
2. The bowls are shaped so they curve as they slow, which is called the bias.
3. When all the bowls of an end are played, each bowl nearer the jack than the other side's nearest scores one shot.
4. Bowls is played as singles, pairs, triples or fours. A game is won on the higher total of shots, ends or sets, as the competition sets.

How long

Games are a set number of ends or shots. In sets play a game is two sets of nine ends, with a three-end tie-breaker if needed.
