Using the site
This site is free to play. No account is required. You may use the puzzles for personal enjoyment, including printing them for your own use.
Leaderboard conduct
Display names must not contain slurs, harassment, impersonation, personal information, or advertising. We may remove any entry that breaks this, or that was clearly produced by automating or tampering with the game, at our discretion and without notice.
Scores are reported by your browser. We validate them for plausibility but cannot cryptographically prove them, so the leaderboard is for fun rather than for anything of value.
Availability
The service is provided “as is”, without warranty of any kind. We do not guarantee uptime, and saved games stored in your browser may be lost if you clear your browser data or if we change the storage format.
Content
Articles, guides and site design are our copyright. Generated puzzles are not — a Sudoku grid is a mathematical arrangement, and you are free to use any puzzle this site produces.
Third parties
Pages may include advertising and analytics from third parties, each governed by its own terms. See our Privacy Policy for what is enabled.
Limitation of liability
To the extent permitted by law, we are not liable for any indirect or consequential loss arising from your use of the site.
