Daily Sudoku
A fresh 9x9 puzzle every day across five difficulty levels — the same board for everyone, with an archive of past days.
A fresh sudoku every day
This daily sudoku gives you a new 9×9 puzzle every calendar day — the same board for everyone, so you can compare how you did with friends. The puzzle above is today’s; use the date arrows to play any earlier day from the archive. Each board is generated from the date itself, has exactly one solution, and can always be finished by logic alone, never by guessing.
Five difficulty levels
Pick a level with the tabs above the board — easy, medium, hard, expert, or evil. Each level gives its own daily puzzle, so there are five fresh boards a day. Easy and medium fall to simple scanning and singles; hard needs pointing pairs and locked candidates; expert and evil ask for advanced patterns like the X-Wing. Your progress, timer, and best time are saved in your browser for each level and date.
How to play
- Tap or click an empty cell, then choose a digit from the number pad (or type 1–9 on a keyboard).
- Turn on Pencil to jot candidate digits into a cell while you work out a placement.
- Use Undo and Erase to take back moves, Hint to reveal one correct cell, and Check to highlight any wrong entries.
- Fill every row, column, and 3×3 box with 1–9 and the board completes itself — the timer stops and your time is saved.
The one rule behind every move: each digit from 1 to 9 appears exactly once in every row, every column, and every 3×3 box. New to the board? Read our full guide to how to play sudoku.
Get better at the daily
The daily puzzle is the best way to build solving habits. When a board stalls, reach for a technique rather than a guess: start with naked and hidden singles, then the wider set of sudoku techniques, and for the expert and evil boards, the X-Wing pattern.

Tips & Tricks

- Open with the fullest row, column or box to get the grid moving.
- If one puzzle stumps you, start a fresh grid and come back with clearer eyes.
Frequently Asked Questions
Is the daily sudoku the same for everyone?
Yes. Each day's puzzle is generated from that calendar date, so every player sees the same board for a given day and difficulty. You can revisit any past day from the archive using the date arrows.
Does a new puzzle really appear every day?
Yes. A fresh board is produced for each date and each of the five difficulty levels, so tomorrow's puzzles differ from today's. Generation is deterministic — tied to the date — so it needs no server and works offline once the page has loaded.
Do I ever need to guess?
No. Every daily board has a single solution reachable by logic alone. If you feel stuck, a deduction has been missed — usually a hidden single or a locked-candidate elimination. Turn on pencil marks and recheck the units around your last placements.
Is my progress saved?
Yes, in your browser. The current board, your pencil marks, elapsed time and best time are stored locally per date and difficulty, so you can leave and come back to finish. Nothing is sent to a server and no account is needed.
