By using sudoku.plyyard.com, you agree to these terms and the Privacy Policy. They cover browser sudoku play, hints, undo, daily challenge, PWA install, and related content. If you do not agree, stop using the service.
What we provide
A free browser sudoku board for personal practice and entertainment. There are no accounts, prize events, rank certification, or multiplayer online rooms.
The service is provided as is. We may change the interface, local storage, daily parameters, or pause features. We do not guarantee uninterrupted or error-free operation on every device or network.
Game rules
We implement standard 9×9 sudoku: each row, column, and 3×3 box holds digits 1–9 once, without conflicting with the given clues. See Sudoku Rules for the full description. If the app behaves differently from that page, we aim to fix the implementation.
Local data and tools
Your current grid, pencil notes, timer, daily markers, and preferences stay in your browser. Hints, check, and undo affect local play only; clearing site data may remove stored records.
Acceptable use
Do not attack the service, disrupt others, automate abusive requests, or misrepresent official rankings on our behalf. Report security issues privately via Contact.
Intellectual property
Design, writing, branding, and code belong to Ply Yard or respective rights holders. The sudoku game concept is not proprietary under these terms; you may not copy the whole site or impersonate us without permission.
Limitation of liability
To the extent permitted by law, we are not liable for indirect loss, data loss, or device compatibility issues. Local game records are for entertainment only, not certified competition results.
