What Is 7Sudoku.com?

7Sudoku.com is a free sudoku site that publishes one new puzzle every day, which you can either play online in a browser-based player or download as a printable PDF. It also offers archived puzzles by difficulty, monthly and seasonal printable puzzle packs with solutions, and a rules section for beginners. It suits anyone who wants a daily logic puzzle without installing an app or creating an account.

What you can do on the site

The homepage is built around the "Sudoku of the day." Each daily entry shows the date and two actions:

• Play online — launches the site's sudoku player app in your browser.
• Print (pdf) — downloads a printable version of that day's puzzle.

Below the daily puzzle, the site links to previous days (for example, yesterday's puzzle and the days before it), so you can catch up on puzzles you missed.

Choose a difficulty

Puzzles are grouped by rating rather than mixed randomly. The available levels are:

The difficulty links sit on the left side of the page, so you can jump straight to the level you want instead of working through the daily puzzle first.

Printable packs and collections

Beyond single puzzles, 7sudoku.com offers:

• Monthly and seasonal puzzle packs — printable books of traditional sudoku, each with solutions at the end.
• Sudoku collections, including 6x6 sudoku for players who want a smaller grid.

The downloads section lists what is currently available, so check there for the active packs rather than assuming a specific month is always in stock.

What makes its puzzles different

Two statements on the site matter if you care about puzzle quality:

1. Every puzzle has only one solution.
2. Every puzzle can be solved by logic — no guessing required.

That second point is the practical one. Many free sudoku sources include puzzles that force you to guess and backtrack, which makes them frustrating for learners and slow for experienced solvers. A logic-only guarantee means you can always reason your way to the answer.

How to start

1. Open 7sudoku.com.
2. If you're new to sudoku, read the Rules of Sudoku section first.
3. Pick a puzzle: use the daily puzzle, or choose a difficulty from the left-hand links.
4. Click Play online to solve it in the browser, or Print to get the PDF.
5. If you get stuck, the site provides yesterday's puzzle solution as a reference.

Who it's for

• Commuters and print solvers who want a PDF they can carry.
• Beginners who need very easy puzzles plus a rules explainer.
• Regular solvers who want a fresh puzzle each day and a difficulty ladder to climb.
• Teachers or group organizers looking for printable packs with answer keys.

If you want timed competitions, leaderboards, or multiplayer features, this isn't that kind of site — it's a straightforward daily puzzle and print resource.
