Terms of Service
Last updated: July 19, 2026
The service
SudoCalm is a free, browser-based sudoku game. It is provided as-is, without warranties; we work to keep it available and your progress safe, but occasional downtime or data loss can happen.
Fair play
Leaderboards only mean something if everyone plays honestly. Scores are validated server-side; using bots, solvers, automation, or exploits to submit scores is not allowed. We may flag, remove, or ban accounts that violate this — including retroactively.
Display names
Pick any name you like, as long as it isn't offensive, misleading, or impersonating someone. We may rename or restrict accounts with abusive names.
Printables and content
Puzzle PDFs are free for personal, non-commercial use — print as many as you like for yourself, your family, or your classroom. Republishing or selling them is not allowed. All site content and the puzzle library remain our property.
Changes
We may update the service and these terms; meaningful changes will be reflected on this page with a new date. Continuing to play after a change means you accept it.
