Terms of Use
Last updated: 28 October 2026
Acceptance of Terms
By accessing or using Sudoku69, you agree to be bound by these Terms of Use. "Sudoku69" means the website sudoku69.com and every official Sudoku69 app. If you do not agree with any part of these terms, please do not use the site or the apps.
Description of Service
Sudoku69 is a free online Sudoku puzzle game offering multiple difficulty levels. The service is provided at no cost and is accessible through any modern web browser and through our official apps. Signing in with Google or Facebook is optional.
Apps
These Terms of Use apply to every official Sudoku69 app, on every platform, as well as to the website. Where they say "the site", read "the site or the app" when you use an app.
Each official app has its own short page with the terms that are specific to its platform:
Pages for other platforms will be added here when those apps are released.
The terms of the store you get an app from, such as the Microsoft Store, also apply to that app. If terms conflict, this is the order:
- The store's own terms, for the licence to install and run the app and for downloads, payments and refunds through the store.
- The platform page of the app.
- These Terms of Use.
Accounts
If you sign in with Google or Facebook, you are responsible for keeping your Google or Facebook credentials secure and for all activity under your account. You must sign in with an account you own. We may suspend or remove accounts that abuse the service or violate these terms. Account data handling is described in our Privacy Policy.
Coins earned in the game have no monetary value. They cannot be bought, sold, transferred or exchanged for money, goods or services.
Every signed-in player who has earned coins is listed on the public Sudoku Ladder, and the fastest solve per puzzle appears on the results screen. Listing is not optional, but you can choose the nickname that is shown. Details are in our Privacy Policy.
