Eight levels
Beginner, Easy, Medium, Hard, Expert and Extreme, plus a quick 6×6 and a large 16×16 with letters. Rated by the technique a puzzle needs, not by how many numbers are given. Every puzzle has exactly one solution.

Left out, on purpose
Most Sudoku apps are built to bring you back tomorrow. This one is built to let you stop.

What is in
Hints that teach
Three steps: where to look, which technique applies and why, then the move. Each hint names the cell by row and column, so you find it without hunting. Unlimited, never counted, never sold.
Quick pencil and lightning mode
One tap fills in every candidate; notes clean themselves up as you place digits. Or pick a digit and tap the cells that take it. Undo goes all the way back.
Mistakes, your way
Checked instantly, counted with a limit and a second chance, or not checked at all. A second error colour for colour-blind players.
Calm on the eyes
Light and dark, four colours, three typefaces for the digits, five sizes. A board that uses the whole width of the screen.
A reminder, if you want one
Off by default. Switch it on and the game tells you after 10, 20 or 30 minutes of play. Once, quietly, without a sound. Then it is your call.
A look inside
Free to try, then your choice
Start free
The first 15 days or 15 puzzles cost nothing, whichever comes first. No card, no sign-up. Both counters are always visible, so nothing surprises you. Hints and helpers are unlimited during the trial, too.

Forever$20one purchase, no subscription
All three unlock the same app; nothing is exclusive to the subscription. The store shows the price in your local currency: 2, 10 and 20 in USD and CHF; other currencies are set by Apple and Google and follow the exchange rate. Subscriptions renew until cancelled in your App Store or Google Play account. Family Sharing is on.
Questions
Why no statistics?
Statistics turn a puzzle into a performance. Once you can see your average time, the app starts asking you to beat it. Sudoku by Ibexo shows you the time of the game you are playing, if you want it, and forgets it afterwards.
What happens after the free trial?
"New game" opens a quiet page with the three options. A game you have already started can always be finished. Nothing pops up during the trial, and there is no countdown.
Subscription or one purchase, what is the difference?
Nothing in the app. The month and the year renew automatically, "Forever" is paid once. Pick what suits how long you think you will play.
How do I cancel?
In your Apple or Google account, like any other subscription. The app itself has nothing to cancel; it simply returns to the trial-ended state.
Can I use it on a second device?
Yes. Sign in with the same Apple ID or Google account and tap "Restore purchase" in the app. Family Sharing is enabled, so one purchase covers your family group.
Does it work offline?
Completely. Puzzles are generated on your phone. Only buying, restoring and redeeming a code need a connection.
Does it have ads or tracking?
Neither. The app sends nothing to us. Your settings, the current game and your purchase status stay on your device. The only network calls are the ones the store makes when you buy or restore. Not measuring anything also keeps us honest: there is no engagement number we could be tempted to push up.
Is it on iPhone and Android?
Yes, on both. Get it from the App Store for iPhone or from Google Play for Android. One purchase belongs to one store account, so a purchase on iPhone does not carry over to Android.
Which languages does the game speak?
English and German today; the game follows your phone's language or the one you pick in Settings. More languages follow. This website and our support are in English.
What is the reminder?
A setting, off by default. Choose 10, 20 or 30 minutes and the game shows a quiet card once that time has passed: "30 minutes played", with "Continue" and "Home". No sound, no vibration, no red. It measures your session, not one puzzle, and pauses when you pause.
iPad or tablet?
The game is made for phones first. It runs on iPad as an iPhone app. A layout for tablets is planned after the launch.
What are codes?
Codes are the App Store's and Google Play's own way of giving an app away. "Redeem code" in the app opens the store's own dialog. We run no code system of our own.
Why "by Ibexo"?
Ibexo is the name of the series. Every game in it is made by the same rules, listed on the Ibexo page. The name puts the puzzle first, because that is what you are looking for, and signs it, so you know what to expect.
Will there be more games like this?
That is the plan: a small series of classic puzzles, each made the same way. The puzzle, and nothing else. New games are listed in the About screen of the game you own; there is no newsletter and no push.
