FAQ
- Where do the puzzles come from?
- From high-quality public databases — the Lichess open database, Lishogi tsume collections, master renju compositions and more — filtered by rating stability and real play counts, then re-verified puzzle by puzzle against this site's own rules engines before release.
- When does the daily reset?
- At midnight in your device's local time. Everyone solves the same puzzle on the same calendar day.
- What if I miss a day?
- Yesterday's puzzle stays solvable for 48 hours and still extends your streak. Every seven consecutive days also banks a streak freeze (up to three) that covers a missed day automatically.
- Do I need an account? Is it free?
- No account, completely free, no ads — like every game on this site. Progress is stored on your own device and can be exported for backup at any time.
