Questions
Is this financial advice?
No — knowledge games only. Nothing here is financial advice.
Are there prizes?
Only when a sponsor funds a prize. Funded prizes and their rules are shown on the challenge card; otherwise you play for rank and badges.
How does the daily round work?
Everyone on this arena gets the same five questions each day, from easy to hard. You get one ranked attempt; practice rounds are unlimited.
How is my score calculated?
100 points per correct answer, up to 50 more for answering quickly, a combo multiplier for answers in a row, and 150 bonus points for a perfect round.
Is it free?
Yes. Playing, streaks, badges and leaderboards are free. Some challenges carry a sponsor-funded prize; the challenge card shows it when one is funded.
