The first edition (2007–2008) was organized by the Football Association of Porto, monitored by the LPFP and Portuguese Football Federation, and was played between clubs from the AF Porto and the AF Braga.

By the second edition, the competition was played on a national level, participating clubs from the North and South Zones, which included the Big Three in Portuguese football: Benfica, Porto and Sporting.

Due to scheduling conflicts between the AF Lisbon and the AF Porto, the competition was split into two leagues in 2010–2011 and altogether abolished by the end of that season.

Every match was played every Wednesday afternoon, much like the older Reserve Leagues.

With regard to the score of the draws: In the replacement rules, three substitution were allowed to be made during the game, plus two at half-time.
