The entrants included the seven clubs with permanent floodlights: Castleford, Leigh, Oldham, St Helens, Swinton, Warrington and Widnes together with Leeds, who installed floodlights in September 1966.
The competition was played in the form of a mini-league with the semi-finals and final stages being on a knock out basis.
