The kettle's on. The grid is fresh. And after a lot of late nights and more test puzzles than we can count, Betty Bee Sudoku is officially open at BettyBeeSudoku.com.
If you've been waiting for a free Sudoku game that feels like a quiet corner of your day instead of a billboard, this one's for you. Come on in.
!Betty Bee Sudoku on a phone: the home screen, the daily challenge with five difficulty levels, and a Sudoku puzzle in progress From left: the home screen, picking today's difficulty, and a puzzle in progress.
Every day, Betty Bee sets out a brand-new set of daily puzzles across five difficulty levels: Easy, Medium, Hard, Extreme, and Insane. Everyone in the world gets the same puzzles on the same day, so you can compare notes with a friend, a neighbor, or your sister three time zones away.
Some people pick one puzzle and savor it with their morning coffee. Some work their way up the ladder before lunch. There's no wrong way to do it. Play today's daily Sudoku and see which kind of solver you are.
We'll say it plainly, because it's the reason we built this: Betty Bee Sudoku has no ads. No pop-ups between puzzles, no "watch a video to get a hint," no flashing banners while you're trying to think.
You came here to solve a puzzle, so that's what you'll get. Just you, a pencil (well, a tap), and 81 little squares.
You can start playing right now, in the browser you're reading this in. There's no app to install and no account to create before your first puzzle.
If you'd like to keep your streaks and stats safe, or play on your phone in the morning and your laptop at night, you can sign in whenever you're ready, and your progress travels with you.
Betty Bee Sudoku also plays in nine languages: English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, and Russian.
We sweated the small stuff so your puzzle time feels calm and personal:
!The same Sudoku puzzle in Betty Bee's light theme and dark theme Same puzzle, two moods: light for bright mornings, dark for late-night solving.
You don't need to be a math person. Sudoku is pure logic: fill each row, column, and 3×3 box with the numbers 1 through 9, no repeats. That's the whole game.
If you're just starting out, our interactive Sudoku tutorial walks you through it one step at a time, and the how to play Sudoku guide covers the rules and common questions.
Already a seasoned solver? Our Sudoku solving techniques library goes from the humble naked single all the way up to the X-Wing and beyond, for the days Insane is living up to its name.
We started Happy Brain Games because we believe a daily puzzle is one of life's small, good habits. A few quiet minutes of focus. A little challenge that's yours alone. That satisfying moment when the last number clicks into place.
We're not making medical promises. But we do think keeping your mind busy with something you enjoy, every single day, is worth making easy and beautiful. That's what Betty Bee is for.
Love playing on your phone? You can add Betty Bee to your home screen today straight from your browser, and it'll open just like an app.
And there's more coming: our mobile app is almost ready, starting with Android. Anything you do on BettyBeeSudoku.com (your streaks, your stats, your friends) will be waiting for you there when it lands. We'll share the news here first.
Is Betty Bee Sudoku really free? Yes. The daily puzzles are free to play every day, with no ads. There's an optional Premium membership for players who want extras, but you never have to pay to enjoy a daily Sudoku.
Do I need to download anything? No. Betty Bee Sudoku runs right in your web browser on a computer, tablet, or phone. Just visit BettyBeeSudoku.com.
Do I need an account? Not to start. Sign in when you'd like to save your progress and play across devices.
When does the new daily puzzle come out? A new set of daily puzzles arrives every day at the same moment for everyone, everywhere.
Is it good for beginners? Absolutely. Start on Easy, try the tutorial, and take your time. Every puzzle has exactly one solution, so it's always a matter of logic, never luck.
That's it. No catch. Just a warm, quiet place to solve a puzzle every day.

If Betty Bee brightens your morning, the kindest thing you can do is share it with someone who loves puzzles as much as you do. A friend who does the newspaper Sudoku. A parent who's always got a puzzle book on the coffee table. That's how a little game like ours finds its people.
Thank you for being here. We can't wait to see you on the leaderboard.
With warmth (and a little buzz), The Happy Brain Games team
