Ninefold

Sudoku

Daily logic, honest levels.

A new sudoku every day, the same for everyone. Levels that mean what they say, and a hint that explains the next step instead of just filling it in.

For iPhone, iPad and Android. Free, with ads; one purchase removes them.

Ninefold on a phone: a sudoku grid in deep blue with the number pad below.

A sudoku that plays fair.

Every puzzle has exactly one answer, and none of them needs a guess. What changes from Easy to Expert is the thinking it takes.

  • Levels that mean it

    Ninefold sets each puzzle's level by the techniques it takes to solve, not by how many numbers are missing. Easy stays relaxing. Expert is a real fight.

  • Hints that teach

    Tap Hint and Ninefold shows you where to look and explains the step in plain words. Tap again if you just want the answer. You pick up pairs and X-wings without reading a manual.

  • Made for focus

    Pencil marks that clean themselves up as you play, unlimited undo, optional mistake marking and a timer you can pause.

  • Playing in a minute

    New to sudoku? A short hands-on tutorial shows you the goal and walks you through your first move.

Questions

Is Ninefold free?

Yes. Ninefold is free to download and to play, all of it. It shows ads between puzzles, never while you play and not in your first session. Short videos are always your choice: they play only when you tap to watch one for extra help.

How do I turn the ads off?

Buy Remove ads once, in the game's settings. It removes the ads in Ninefold for good, and it belongs to your Apple Account or Google account, so you can restore it on a new phone or after reinstalling at no charge.

Does it work offline?

Yes. Every level and the daily puzzle work without a connection, on a plane or underground.

Do I need an account?

No. There is nothing to sign up for. Your puzzles, times and streak stay on your device.

What about my privacy?

We do not collect your personal information, and there are no servers of ours that the app talks to. The ads come from Google AdMob, which collects some device and usage data to show and count them; where the law requires it, you are asked first. The details are in our privacy policy.

Which devices and languages?

iPhone, iPad, and Android phones and tablets. The game speaks 26 languages and follows your phone's language.
