Ninebloom: Sudoku Puzzles

Sudoku that grows with you.

Ninebloom is a calm, colourful Sudoku with hints that explain the technique, not just the answer. Every puzzle is rated by the skills it actually needs, so Hard really is hard, and you can see yourself getting better.

HINTS THAT TEACH
• Every hint names the technique (naked single, hidden pair, pointing pair, X-Wing and more) and shows why
• Choose to 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

DIFFICULTY YOU CAN TRUST
• More than 10,000 classic puzzles across six levels, from Beginner to Fiendish
• Each one checked to have exactly one solution and rated by the techniques it needs
• Played in order (#1, #2, ...), so you always know how far you have come

A PUZZLE A DAY
• A new daily puzzle, the same for everyone
• Streaks that forgive: streak freezes cover a missed day
• A weekly challenge to set a personal best
• A bloom garden that grows a plant for every puzzle you solve

PLAY YOUR WAY
• Notes, corner-and-centre pencil marks, colouring, zoom
• No mistake limit unless you want one; save a point and rewind a guess
• Pause hides the board, so your time is honest
• Large print, high contrast, screen-reader support and a left-handed layout
• Type in a puzzle from a book or newspaper and play it here

CALM AND PRIVATE
• Works offline. No account, no sign-up
• Gentle sounds and optional calm music
• Themes for light and dark, made for phones and tablets
