Sudoku More Daily Puzzles
Challenge yourself with a different sudoku variant every day. Each puzzle uses the same daily system — one new puzzle, same for everyone, with streaks and sharing.
Daily Sudoku: A Free New Puzzle Every Day
Welcome to Daily Sudoku — a fresh 9×9 puzzle delivered every day at midnight. Unlike our classic sudoku mode where you can generate as many puzzles as you like, Daily Sudoku gives you one puzzle per day that's identical for every player worldwide. It's a shared challenge: compare your time and mistakes with friends, build your streak, and see how you stack up against the global community.
The daily sudoku format follows the tradition of newspaper puzzles that have appeared in publications like The Times and The New York Times since the mid-2000s — but with modern features like streak tracking, spoiler-free sharing, and a full puzzle archive. Whether you solve over morning coffee or during a lunch break, today's daily sudoku is waiting for you.
Every day at midnight (your local time), a new puzzle appears. Difficulty follows a weekly cycle: Monday and Tuesday are Easy, Wednesday and Thursday are Medium, Friday and Saturday are Hard, and Sunday is Expert. This mirrors the classic newspaper tradition of puzzles getting progressively harder through the week.
🔥 Why Play a Daily Sudoku Puzzle?
Daily puzzles tap into the same psychology that made Wordle a global phenomenon. When everyone solves the same puzzle on the same day, it becomes a conversation starter. You can share your results without spoiling the solution, compare solving times, and challenge friends to beat your streak. The daily format also builds a healthy habit — a few minutes of focused logical thinking every morning sharpens your concentration for the rest of the day.
Research suggests that regular puzzle-solving helps maintain cognitive agility, improves working memory, and reduces stress. A daily sudoku is like a quick workout for your brain — short enough to fit into any schedule, challenging enough to keep you engaged.
Studies published in the International Journal of Geriatric Psychiatry found that adults who regularly solve number puzzles like sudoku have brain function equivalent to people up to 10 years younger. A daily sudoku habit isn't just fun — it's an investment in long-term brain health.
⭐ Daily Difficulty Levels Explained
The difficulty of each day's puzzle is determined by the day of the week, following a pattern familiar to anyone who's solved newspaper sudoku:
- Monday & Tuesday — Easy — More given digits (around 38–45 clues). Solvable with basic scanning and naked singles. Perfect for warming up or if you're new to sudoku.
- Wednesday & Thursday — Medium — Fewer clues (30–36). You'll need hidden singles and candidate elimination. The sweet spot for most daily solvers.
- Friday & Saturday — Hard — Significantly fewer clues (25–29). Requires intermediate techniques like naked pairs, pointing pairs, and box/line reduction.
- Sunday — Expert — Minimal clues (22–25). Demands advanced strategies such as X-Wing and XY-Wing. The weekly boss puzzle for serious solvers.

📊 Streaks and Sharing
Your streak counts consecutive days you've completed the daily sudoku puzzle. Solve today's puzzle and your streak grows by one. Miss a day and it resets to zero — but your best streak is always recorded so you can try to beat your personal record.
When you complete a puzzle, hit the Share button to copy a spoiler-free results card showing your solving time, mistake count, and current streak. Paste it in group chats, social media, or community forums — no solution details are revealed, so you can't accidentally spoil the puzzle for anyone else.
Start your streak on a Monday when the puzzle is Easy, and build confidence before the difficulty ramps up. By the time Sunday's Expert puzzle arrives, you'll have momentum — and six days of practice — on your side.
📅 The Puzzle Archive
Missed a day? Use the calendar picker below the puzzle to select any past date and play that day's puzzle. Archive puzzles are generated from the same mathematical seed as the original, so you'll get the exact puzzle everyone else solved that day — right down to the placement of every given digit.
Note that archive solves don't count toward your current streak. You'll need to solve today's puzzle to keep your streak alive. However, archive play is a great way to practise at specific difficulty levels — pick any Friday for a Hard workout, or any Sunday if you want to test yourself against an Expert grid.
📱 Play on Any Device
Our daily sudoku works on any device with a web browser — desktop, tablet, or phone. The grid automatically resizes for your screen, and your progress is saved locally so you can start solving on your commute and finish at home. No app download required, no account to create, and no ads blocking the grid.
Your game progress, streak data, and solve history are stored in your browser's local storage. This means they persist between sessions on the same device and browser, but won't sync across different devices. Clearing your browser data will reset your streak.
🎮 Daily Sudoku Variants
Once you've made the classic daily sudoku part of your routine, expand your challenge with our daily variant puzzles. Each variant uses the same one-puzzle-per-day system with streak tracking and sharing:
- Daily Killer Sudoku — Cage sums replace standard givens, blending sudoku logic with arithmetic.
- Daily Jigsaw Sudoku — Irregular jigsaw-shaped regions replace the standard 3×3 boxes.
- Daily X-Sudoku — Both main diagonals must also contain 1–9, adding two extra constraints.
- Daily Samurai Sudoku — Five overlapping grids for a longer, more complex daily challenge.
- Daily Sandwich Sudoku — Clues on the edges tell you the sum of digits between the 1 and 9 in each row and column.
- Daily Wordoku — Letters replace numbers — solve the grid and find the hidden word.
You can also choose a fixed difficulty level: Daily Easy, Daily Medium, or Daily Hard — each delivers the same difficulty puzzle every day, regardless of the day of the week.
