How does the rivalry quiz work?

You get ten questions. Each names two teams and asks which one leads their all-time head-to-head series. Pick a side, then see the real record. Today's quiz is the same ten questions for everyone on a given day, and the random quiz deals a fresh set each time.

Where do the questions come from?

From 3,135 series between current teams in the NFL, MLB, NBA, NHL, college football and WNBA, covering 428,021 games. A series needs at least 10 meetings and a clear leader; exactly level series are never asked. Every record is the one on that matchup's page.

How often does the quiz change?

Today's quiz changes at midnight in your time zone. The random quiz is unlimited, so you can play as many sets as you like.

Can I play an earlier day's quiz?

Yes. When you finish a daily quiz, use Previous day, or open a shared score link: it carries its date, so you get the same ten questions your friend did. Past days are dealt from today's records, so a day replayed after new games can differ slightly.

What is the most-played series in the quiz?

Chicago Cubs vs Pittsburgh Pirates, with 2635 meetings since 1887.

Ties are listed in the record you see after answering, but the leader is decided by wins alone.
