Districts find, by competition, a person to represent them at the national final. While sponsored by Trans Tours (1975 to 1978) districts were required to run a separate Trans Tours club event and then a district champion of champions. In 1979 the requirement to have club events was rescinded.
The event has been sponsored by Henselite from 1986. All of the districts enter their singles champion who each play four games of twelve ends in section play and require at least two wins and a draw to qualify for post section play.
A Plate Event for non-qualifiers was introduced in 2012.
In 2020 districts were required to find a winner to play-off in eight regional zones The zone winners compete in a round-robin tournament in the national final.
