Gazette Reader FAQ & Help Desk
Answers about email delivery, printing on paper, puzzle difficulty, and your account.
What time does The Sudoku Daily arrive?
By default, your daily Sudoku PDF is delivered to your inbox at 07:00 AM local time every morning. You can customize the delivery time (e.g. 06:30 AM or 8:00 PM) and choose weekdays or weekends in your account settings.
What should I do if I haven't received today's email?
Please check your spam or promotions folder first. We strongly recommend adding daily@sudokuhabit.com to your email contacts or whitelist. You can also download today's PDF anytime directly from the Today's Gazette or Print Edition page.
Is the daily email subscription free?
Web printing and downloads are free forever. Daily email delivery includes a 7-day free trial with no credit card required. After the trial, upgrade to keep receiving puzzles—or cancel anytime.
Can I temporarily pause delivery while on vacation?
Yes. In your account settings, you can pause delivery anytime during holidays. When you return, unpause with a single click and resume daily deliveries without resetting your streaks.
What paper and printer do you recommend?
Any standard home or office monochrome laser or inkjet printer works great. We recommend 70g–80g standard A4 paper (or US Letter). Our PDFs are vector-optimized with crisp contrast to prevent bleed-through.
Should I choose 1 puzzle per page or 2 puzzles per page?
Choose '1 puzzle per page' for spacious note-taking and clear notation margin. Choose '2 puzzles per page' for compact double-sided printing and convenient commuter pocket carrying.
What if the printed page edges are clipped?
In your system print dialog, make sure scaling is set to 'Fit to Printable Area' or '100% Actual Size', and verify that your printer tray paper matches the downloaded format (A4 or US Letter).
How are the difficulty levels graded?
We provide 4 curated tiers: Easy (naked singles and basic line exclusions), Medium (hidden pairs and box-line reductions), Hard (triples, X-Wings, and intersections), and Expert (advanced chain logic for seasoned solvers).
Do puzzles have unique solutions? Are solutions included?
Yes. Every puzzle is mathematically verified to guarantee a single unique logical solution with no guessing required. Solutions are printed inverted at the bottom of each page and accessible via QR code.
How does photo grading work?
Once finished on paper, simply reply to your daily morning email with a photo of your handwritten sheet attached. Our automated system recognizes your grid in seconds and emails back your score and diagnostics.
Do I need a password to sign in?
No complex passwords required. We support secure one-click Google Sign-In and fast email magic login codes.
Is my email data private? Will I get marketing spam?
Never. We value reader focus and tranquility. Your email address is strictly used for delivering your daily paper and necessary service updates. We never share or sell your data.
How do I unsubscribe?
Every email contains a 1-click unsubscribe link at the footer. You can also pause, adjust, or delete your account at any time in your Settings page.
