Teams from across the county play in two divisions during the winter months, with each team playing the other teams in its division on a 'Home' and 'Away' basis.

Each match consists of four games - singles, pairs, triples and rinks (4s). For each game, points are awarded as follows - 2 points for a win, 1 point for a draw, and 0 points for a loss. So, there are 8 points awarded between the two teams in each match. Teams are ranked according to the number of points scored during the season.
