Nine: Sudoku Puzzle
Daily sudoku, easy to evil
Free · Designed for iPad. Not verified for macOS.
Free and offline. One new sudoku a day, the same for everyone, five levels from Easy to Evil, and hints that name the technique instead of just the number.
A free, offline sudoku with one new puzzle a day, the same for every player in the world. Five levels, Easy to Evil, each one graded by the technique it actually demands.
Nine is a sudoku you can trust.
Every sudoku is graded by the technique it actually demands, not by how many squares are blank. When Nine says Expert, you will need an expert's move, not just a grid with fewer clues. Five levels, from Easy to Evil, each one verified strictly harder than the last: Easy asks for the simplest logic, Evil will not resolve without a real X-Wing.
ONE SUDOKU A DAY, THE SAME FOR EVERYONE
Every player in the world gets the identical daily sudoku, resetting at midnight UTC. Your time is comparable to anyone else's, so today's ladder means something: see how you rank worldwide, right next to your own personal best for that difficulty. Miss a day and the streak breaks, so keep it going.
HINTS THAT TEACH
Stuck? A hint fills the next square you could have deduced yourself, and names the technique that proves it: naked single, hidden pair, pointing pair, X-Wing. Most sudoku apps just hand you the number. This one shows you the reasoning, so the next grid gets a little easier on its own. Each hint you take adds a small time penalty to your recorded and ranked time, so speed and honesty both still count.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Nine now speaks thirteen languages. German, Italian, Turkish, Hindi and Arabic have been added, and the app still follows your device on its own.
Arabic is laid out right to left throughout. The board and the number pad are not: a sudoku grid reads the same in every language.
