Tournament Format
From 1993 to 1997, the teams were divided to two groups in the elimination round. The teams in the same group will play against each other once and against teams in the other group twice. After the eliminations, the top five teams will advance to a double-round robin semifinals. A playoff incentive will be given to a team that will win five of their eight semifinal games should they fail to get the top two finals berths. The top two teams (or the #1 team and the winner of the playoff between team with at least 5 semifinal wins and the #2 team) will face each other in a best-of-seven championship series. In 1995, a slightly modified post eliminations format was adopted. Instead, the top six teams will advance to the quarterfinal round for another single round robin. The top four team will then be seeded in a best-of-five series with the winners advancing to the finals.
In 1998, the league adopted a quarterfinal-semifinal playoff format with the top two seeds advancing automatically to the semifinals and the next four teams will be matched up in the quarterfinals. The winners will advance to the semifinal round and to compete against the two top seeded teams in a best-of-five series. The winners of the semifinal round will then advance to the best-of-seven championship series. This format was slightly modified due to the entry of the Tanduay Rhum Masters in 1999. The top eight teams after a round-robin eliminations will advance to the quarterfinals. The top two seeds will have a twice-to-beat advantage against the last two seeded teams. Other seeded teams will compete in a best-of-three playoffs. The winners will compete in a best-of-five semifinals series. Then the winners of the semifinals will advance to a best-of-seven finals series.
After the reintroduction of the tournament in 2011, the league adopted a tournament format similar on what was used in 1998. The top two teams will gain automatic semifinals seed while the next four teams will compete in a best-of-three quarterfinals.
The height limit for import players varies from every year. In the tournament's reintroduction 2011, the height limit was 6'4". In 2012, the league removed the height restrictions.
