Community rules

By using Open Sudoku you agree to keep the game fair for everyone:

• Play fair. Ranked scores are for genuine solves.
• No abuse of the leaderboard API. Automated or scripted submissions that bypass the game are not allowed.
• Respect rate limits. The server caps how often sessions can start and scores can be submitted; flooding the API will get requests rejected.
• One account per person. Don't create multiple accounts to game the leaderboard.

Disclaimer

Open Sudoku is provided for entertainment. Scores are verified server-side using the methods described on the Fair Play page, but this is not contest-grade arbitration, and we make no guarantee about the accuracy or completeness of any ranking. The software is provided "as is", without warranty of any kind.
