What these rankings mean
- These are Sudoku a Day rankings, not official national rankings. The country shown comes from each player's profile.
- The rating board includes public players with a rating and at least 10 recorded completions. Matching public identities are combined using the same rules as the main leaderboard.
- Rating, speed and number of completions measure different things. Compare the same puzzle and difficulty when looking at solve times. The speed and daily boards apply their own result-eligibility rules.
- This page shows the latest published rating ranking. It does not name monthly winners or claim an independently verified world record.
