Prefer to play in your browser?

Open daily Sudoku without installing the iPhone app. Choose Easy, Medium, Hard, Expert or Master to start at a particular level. Browser and app features are described separately; check the controls in the version you use.

Prefer paper?

The website's printable chooser provides free downloads without an email subscription. Select a paper size and preview the file. Choose a weekly pack with answers if you want a separate solution page.

Before you choose

Try entering a digit, adding a note and checking the assistance settings. If you want to use the app during travel, open a puzzle offline before relying on it. Review the purchase screen for the features, price and renewal terms of any optional offer.
