Thirty-two participating squads will square off starting Saturday in this year’s staging of University of the Philippines Diliman Ultimate Organization’s (UP DUO) Apollo 10 tournament at the Sunken Garden of the UP DIliman campus.

The two-day tournament, set on October 5 and 12, provides a tough challenge for competitors through modified rules where teams could only field 10 players in their roster, and will not allow to make in-game substitutions in a battle that tests the players’ endurance.

Teams are split into two categories: eight teams competing in the Under-21 division, while 24 will be competing in the elite division.

Interested parties may contact event heads Bea Reyes at 0917 889 0126, or Jess De Leon at 0917 823 0993; or visit UP DUO’s Facebook page, Twitter account, and website for more tournament details and information.
