Terms of Use
Use SudokuHint freely. Be reasonable. Do not try to break it.
Last updated June 21, 2026
The service
SudokuHint (the "site") is a free Sudoku game and tutorial library at sudokuhint.com. There is no account, no subscription, and no payment. You may use the site for personal, non-commercial enjoyment and learning.
As-is, no warranty
The site is provided "as is." The puzzles are generated by an algorithm and the hint engine is a heuristic — both are extensively tested but not guaranteed to be perfect. We are not liable for any frustration, lost streaks, or spilled coffee.
Fair use
Do not attempt to abuse, overload, or scrape the site. Do not use automated tools to generate puzzles in bulk. Play nice.
Intellectual property
The code, design, and content of SudokuHint belong to the project authors. You may not republish the site or its content without permission.
Changes
These terms may change occasionally. Continued use of the site means you accept the current terms.
