How does the NBA 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 NBA questions come from?

From 425 series between current NBA teams, covering 70,969 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 NBA series in the quiz?

Boston Celtics vs Philadelphia 76ers, with 598 meetings since 1949-50.

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