Disclaimer
Number Forecast provides Sudoku puzzles and helper controls for entertainment, learning, and casual practice. The site is not a professional training tool, educational certification program, gambling product, or guaranteed performance system.
Puzzle accuracy
The included puzzle data is intended to be solvable and internally consistent. However, static puzzle sets, labels, and validation messages may contain errors. If you notice a puzzle issue, use the contact page to report the difficulty level and the square involved.
Static website behavior
This version runs in the browser without a backend. The contact form displays a local confirmation message, the Sudoku board checks entries against puzzle data in the page, and no server-side email delivery or account storage is included.
External responsibilities
If the site is later hosted with analytics, ads, email delivery, or third-party services, those services may have their own terms and privacy practices. Site owners should review those services before launch and update the public pages accordingly.
- Use the puzzles for recreation and practice.
- Do not rely on the site for saved records unless a save feature is explicitly added.
- Refresh the page if the board behaves unexpectedly during a static demo session.
