About Krilliarmus
Krilliarmus is a free daily trivia game for fans of the books, films and games about Hogwarts and its world. Every day there are seven questions. Rarer answers fly higher and score more.
Unofficial fan project
Krilliarmus is an unofficial, non-commercial fan project. It is not affiliated with, sponsored by or endorsed by J.K. Rowling, Warner Bros. Entertainment, Wizarding World Digital, Bloomsbury, Scholastic, Portkey Games or any of their partners.
Harry Potter, Hogwarts, Quidditch and related names and characters are trademarks of their respective owners. They are used here only to refer to the books, films and games the questions are about. No official artwork, logos, music, film footage or text from the books is used. All art in the game is original and drawn in code.
The daily "rarer answers score more" format was inspired by trivia games like Krillion. Krilliarmus is not affiliated with Krillion, and its art, wording and code are its own.
The game is free, has no ads, sells nothing and collects no payments.

Privacy
- No accounts, no cookies, no ads, no tracking or analytics.
- Your streak, scores, settings and the questions you've already seen are saved only in your own browser (local storage). Clear this site's data in your browser settings to delete them.
- If the daily scoreboard is switched on, finishing a daily flight sends an anonymous row with the day number, your score and the rarity of your seven answers. It is used only for the "You vs. today's players" chart. No name, account or device ID is sent, and nobody can read individual rows back.
- Like any website, the hosting provider (Netlify) and, if switched on, the scoreboard provider (Supabase) may keep standard server logs, such as IP addresses, for security and reliability.
- The game loads nothing from other websites. Its fonts and code are all served from this site.
