It was first contested in 1973–74 and later in the decade the competition's name was changed the BCCP Invitation Tournament. In 1980–81 it became the PACO Cup and remained so for a further five seasons. For the rest of the decade the tournament didn't take place and it wasn't until the 1990s that is returned, albeit sporadically. The Trophy finally became a permanent fixture again in 2005–06.
The Pentangular Trophy is generally contested between five teams who play each other on a round-robin basis. Unlike other Pakistani tournaments there is no final and the winner is the side that topped the table with the most points. Currently the top three placed teams from the Patron's Trophy and the finalists from the Quaid-e-Azam Trophy qualify for the tournament.
