Terms of use

Last updated 26 September 2026.

iLoveSudoku lets you play killer sudoku in a browser for free. You may print reasonable numbers of puzzles for personal, classroom, or club use if you leave the puzzle numbers and the iLoveSudoku name visible. You may not republish the puzzle bank as your own product, scrape it in bulk, or frame the site in a way that hides where it comes from.

Puzzles are provided as-is. We check uniqueness and a logical path before publication, and we correct or retire a board when a mistake is confirmed. We do not warrant that every puzzle will match your taste or your expected time.

Do not abuse the site: no attempts to disrupt it, no automated traffic that degrades it for players, no unlawful content in any name or message you submit if leaderboards are added. We may block traffic that does those things.

The site may show ads. Gameplay is not interrupted by interstitials. Optional paid extras, if they are added later, will be described at the point of purchase.

These terms are governed by the laws that apply where the operator resides, without regard to conflict-of-law rules. Questions: hello@ilovesudoku.app.
