Autosave — Your current game is saved in your browser after every move. If you leave the page, you'll be able to resume exactly where you left off. Saves are kept for 7 days.
Settings ⚙️ — For advanced players, the gear at the top of the page turns on the ✏️ Auto button: it fills in every candidate of the grid at once, or only the cleaned candidates (locked candidates removed). This second option counts as a hint: the game won’t count towards “No hints”. You’ll also find large print there, for easier reading.
Shared stats — These stats cover random puzzles. They are shared with the 🎲 tab of the Daily puzzle page, where daily puzzles have their own stats. They're stored locally in your browser and never sent to a server.
Classic 9×9 sudoku, free and no sign-up required
The 9×9 sudoku grid is the best-known version of the game: 81 cells arranged in nine 3×3 boxes. The idea is simple to state, trickier to master: fill every row, every column, and every box with the numbers 1 to 9, without ever repeating a number in the same row, column, or box.
Sudoku-Land offers 5 difficulty levels (easy, medium, hard, expert, evil), notes mode for tracking candidates, a hint system, automatic autosave, a dark theme and a ⚙️ Settings menu (auto notes, large print…). Everything runs straight in your browser: nothing to install, no account to create, on desktop and mobile alike. Every game here uses a different random grid.

Frequently asked questions
How long does it take to solve a 9×9 sudoku grid?
A few minutes on easy, often 15 to 30 minutes or more on expert, depending on your experience and the techniques you know.
Is 9×9 sudoku too hard for beginners?
Not on easy mode. But if you're new to sudoku, Sudoku-Land's 4×4, 6×6, or 8×8 grids let you build up gradually before tackling the 9×9.
Do I need an account or an app to play?
No. Sudoku-Land runs straight in your browser, free and with no sign-up, on desktop, tablet, or mobile. Your game in progress and your statistics are saved in your browser: you can close the tab and pick up later on the same device.
How can I get better at sudoku faster?
By learning solving techniques (see How to play) and practicing regularly. If a difficulty level is blocking you, dropping down temporarily, even to an 8×8 grid, helps build solid fundamentals.
