The postseason tournament began on October 5, four days after the conclusion of the regular season, and ended on December 7, 2024.
Seeding is based on wins, with tiebreaker rules applied should multiple teams have the same record.
During the first two rounds, two games within the same division are played in a gameday, with homecourt advantage alternating between the higher-seeded teams of each series.

After Valandre Chauca tied the game at 63, San Juan went on an eight-point scoring run as the Knights won by 12 points and advance to the division semifinals.
Nikko Panganiban and Orlan Wamar Jr. also scored double digits while Agem Miranda led the assists department with 9.
The latter part of the fourth quarter saw multiple ejections, including the leading scorers for both teams in Jeramer Cabanag and Greg Slaughter.
In the final moments, as Caloocan led by three, Jorey Napoles got fouled as Joco Tayongtong made one of two free throws to make it a two-possession game with 4.7 seconds remaining.
