It is managed and organised by the Polish Basketball League (PLK).

The creation of the tournament was initiated in 1933, by the Polish Association of Sports Games (PZGS), an organisation which carried out the organisation of national sports competitions in Poland.

Since the 2012 season, a Final Eight format is used, in which the highest placed teams from the first half of a given Polish Basketball League (PLK) regular season qualify.
