Terms of Use

Last updated: June 23, 2026

Using Bundoku

Bundoku is provided free of charge for your personal, non-commercial enjoyment. By playing, you agree to use it in a lawful, reasonable way and not to disrupt or abuse the service.

No warranty

The game is provided "as is", without warranties of any kind. We do our best to keep puzzles solvable and the site working, but we cannot guarantee it will be uninterrupted or error-free. Your saved progress lives in your browser and may be lost if you clear site data.

Content and brand

"Sudoku" is a generic puzzle term used descriptively. The Bundoku name, art, and original puzzles are ours; please do not redistribute them as your own. All puzzles are generated by Bundoku, not copied from any published catalog.

Changes

We may update these terms as the game evolves. Continued play after a change means you accept the updated terms.
