Questions
Are these medically reviewed?
Challenges are habit-based community games, not medical advice. Always consult a professional for health decisions.
What does it cost?
Free to play. Scores and streaks are tracked on the leaderboard.
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.
