What it does
The Sudoku that teaches you to solve
Fill every row, column and box with 1 to 9. Ninebloom shows you how the experts do it, one named technique at a time.
Hints that teach
Every hint names the move, and shows why.
Naked single, pointing pair, X-Wing, Swordfish and more. A hint highlights the cells that matter and says in plain words why the digit goes there. Let Ninebloom place it, or close the hint and place it yourself.
- Unlimited and free. No coins, and no video to watch for a hint
- Learn walks through 12 techniques, from the simplest up
- Every puzzle is checked to have exactly one solution
A puzzle a day
A daily puzzle, and a garden that grows.
A new daily puzzle, the same for everyone, and a weekly challenge to set a personal best. Every puzzle you solve grows a plant in your bloom garden. Harder puzzles grow showier ones.
- Streaks that forgive: streak freezes cover a missed day
- Played in order (#1, #2, …), so you always know how far you have come
- Badges for clean sheets, streaks and harder levels
Play your way
Every tool, and none of the pressure.
Notes with corner and centre marks, colouring and zoom. No mistake limit unless you want one, and pause hides the board so your time is honest.
- Large print, high contrast, screen-reader play and a left-handed layout
- Type in a puzzle from a book or newspaper and play it here
- Gentle sounds, optional calm music and themes for light and dark
Difficulty you can trust
Six levels, rated by the techniques they need
Not by how many digits are missing. When you move up a level, you meet a new idea.

Questions
Good to know
When can I get it?
Ninebloom is in testing now and coming soon to Google Play for Android phones and tablets. An iPhone and iPad version for the App Store follows. Email support@leafyorb.com and we will tell you when it is out.
Is it free?
Yes. Every classic puzzle at every level, the daily puzzle and unlimited hints are free for good. Ninebloom Plus is optional and adds monthly packs, every way to play and more.
Are there ads?
Only if you choose one. Free players can watch an optional short video for a small bonus, like a streak freeze. Nothing free waits behind an ad, and Plus members never see one.
What makes the levels different?
Each puzzle is rated by the techniques it needs to solve, not by how many digits are given. Beginner needs only naked singles, each level adds a technique, and Fiendish goes beyond all of them. Hints still explain advanced moves like the Swordfish and XY-Wing.
Do I need an account or an internet connection?
No account is needed, and it works fully offline. Your puzzles, progress and settings stay on your device.
Can I play a puzzle from a newspaper?
Yes. Type it in and play it with all the same tools and hints. With Plus you can also scan it from a photo; the photo is read on your device and never uploaded.
Who makes it, and how do I get help?
Ninebloom is made by Leafy Orb. Email support@leafyorb.com or see Support.
Coming soon. Bring a pencil.
