You start play from either of the yard lines extending from corner 1 to the centre of the South boundary, or from corner 3 to the centre of the North boundary. The yard lines are a mallets length in from the boundary lines. Either ball of a side can be played at the start of a turn once all four balls have been played onto the lawn. All balls may be roqueted once each turn and, if the next hoop is run, all may be roqueted again, etc. If a ball plays out of turn the balls are replaced, no points are scored and that side loses its turn.
Special rules deal with striking the wrong ball.
You cannot roquet balls before running hoop 1 nor roquet balls which have not been through hoop 1. You can roquet balls as soon as they are on the lawn. Your turn ends if a ball leaves the lawn after the roquet. You however remain live on that ball. It does not matter if the striker's ball leaves the lawn.
