The cup is contested by a total of 28 clubs: 18 lower level sides qualify via regional cups organised by the Intercommunal football associations. They are joined by the 6 lower placed top flight clubs and are reduced to 12 clubs through the first round proper. They are then joined by the best 4 top flight clubs who automatically enter the second round proper. The games are played in a single leg knock-out format until the quarter-finals and semi-finals when home and away matches are played and aggregate scores are taken into account. Since 2005 the final is also held as a single-legged match, although it was a two-legged affair in the period between 1994 and 2004.
As of 2014, a total of 13 clubs have reached the cup finals and the most successful side in the history of the competition is Maribor, who have triumphed 8 times in their 12 cup final appearances. They are followed by Olimpija, who won 4 titles before folding in 2004. Primorje hold the record for most appearances in the final without winning the title, finishing as runners-up in three consecutive finals between 1996 and 1998. Aluminij is the only side from outside the top flight which managed to reach the cup final, having finished as runners-up in 2002 after a 6–1 aggregate defeat to Gorica.
A. ^ The original Olimpija, which traced its roots back to 1945 went bankrupt and ended in 2004. In 2005, a successor club called NK Bežigrad was founded which started competing in the fifth league. The club won consecutive promotions and at the start of the 2008–09 season, it was renamed to Olimpija, before being promoted to top flight for the 2009–10 season. However, despite club officials and fans claims that the new Olimpija is the defunct club's successor, neither the Football Asoociation of Slovenia, the Slovenian First League nor UEFA recognize Olimpija's titles and statistics before 2005 as being part of the 2005 founded Olimpija's track record.
B. ^ The original Mura, which was traced its roots back to 1924 went bankrupt and folded in 2004. In 2005, a successor club called ND Mura 05 was founded which started competing in the 3rd league. Despite club officials and fans claims that the new Mura is the defunct club's successor, neither the Football Asoociation of Slovenia, the Slovenian First League nor UEFA recognize Mura's titles and statistics before 2005 as being part of the 2005-founded Mura's track record.
