From Pool HQ, click Make Picks or Picks (or open the pool from Sports Central). Select your entry if you have more than one, then pick a winner for each game.
You can change picks until the pool's deadline — shown on the yellow banner and on Sports Central. After lock, picks for started games are frozen; games that have not kicked off may still be editable depending on pool rules.
Multiple entries
If the commissioner allows multiple entries per person, each entry has its own pick sheet and standings row. Switch entries from the dropdown on the picks page.
