## What is Sudoku Pro?

Sudoku Pro is both: a full Sudoku to play, and a trainer that makes you better at it.

Everything you expect from a Sudoku is here: 4x4, 6x6 and 9x9 across four tiers, plus Killer and Samurai, with notes, focus mode, undo, a daily puzzle, streaks and statistics. Every puzzle is generated fresh and has exactly one solution.

Getting better comes along for the ride. Every hint names the technique it just used, and tutorial mode explains it on your own grid instead of a textbook example. If you only want to play, you never have to switch it on.

I am a solo dev and I’ve been a Sudoku lover for years, but lately, finding a good app has felt like a puzzle of its own. And not the fun kind.

I was tired of subscriptions. And why does a puzzle app need to track my location or share my data with advertisers? There is visual noise like flashing banners and "collect 100 gems" pop-ups that break my focus. I just want my coffee and a Sudoku. Call me a grumpy old man, but that isn’t much to ask for!

I wanted a "Zen" experience. So, I built it myself.

My goal: to create a clean, honest Sudoku for the App Store.
* Pay once, keep forever: no subscriptions, no hidden IAPs, no ads, no account. Just a fair price for a tool that does its job.
* Everything on your device: the app needs no internet. Your puzzles, your streak and your statistics stay where they belong. I don’t track you. I only care about your feedback!
* Sudoku for kids and beginners: I included 4x4 and 6x6 grids so I could play with my kids and teach them the logic, while keeping the Expert 9x9 tough enough for the pros.

Three ways to play, one purchase:
* Classic in 4x4, 6x6 and 9x9, across four difficulty tiers.
* Killer: cages with sums that tell you right away whether a sum still works out.
* Samurai (iPad only): five overlapping 9x9 grids solved as one 21x21 frame.

On iPad: the newspaper edition.
The iPad gets a world of its own: a front page, an almanac, its own typography. Not a stretched iPhone. In pen mode the keypad folds away and the board takes the space. Prefer the familiar look? Switch to the classic layout.

So what else is under the hood?
* Hints that teach instead of tell: the solver names the technique it applied. It knows 13, including Naked Single, Hidden Single, X-Wing, Swordfish, Y-Wing, Jellyfish and XY-Chain.
* Tutorial mode: learn advanced logic (not just guessing!) on your current grid, not on a textbook example.
* Unique grids: every game is generated fresh, proven unique and solvable with its own tier’s techniques.
* Daily puzzle: the same puzzle worldwide on any given day, with a streak and a calendar.
* Ten handcrafted themes, from rainbow colors to high contrast.
* Statistics, best streak and 15 achievements, all on your device with no sign-in.
* Notes, blocked notes, auto notes, focus mode and helper mode.
* Share your logic: export a timelapse video of your solve.
* 45 languages.
* A daily reminder at a time you choose, but only if you want one.

Accessibility is built in, not retrofitted: VoiceOver throughout, Dynamic Type on the board, a high-contrast theme, haptics you can switch off, and a dot notation for anyone who reads patterns faster than digits.

Own the grid and rediscover the pure joy of logic.

Happy puzzling,
Tobias

### 5/5 — Geht gar nicht mehr

*2026-08-07*

Vor Version 4 konnte man Farben mit ordentlichen Kontrasten auswählen. Jetzt stehen nur noch blasse Pastellfarben zur Auswahl. So macht es keinen Spaß mehr.

Mit dem Update auf 4.1 ist wider alles im Lot. 
Entwickler regiert sehr schnell.

**Developer response:** Hi! Das Spiel folgt seit Version 4 dem Modus des iPhones beim Hell- und Dunkelmodus. Die aktuelle Version 4.1 hat einen neuen Schalter „Dunkelmodus“ in den Einstellungen, der den alten Zustand wieder herstellt. Mede dich gerne per Email, wenn noch etwas fehlt!

### 5/5 — Großartige Sudoku-App

*2026-06-25*

Großartige Sudoku-App, wahrscheinlich die beste im App Store.
Einfach nur Sudoku – keine Werbung, In-App-Käufe oder Ablenkung.

PS: Hatte den deutschen Entwickler wegen eines ganz kleinen Verbesserungsvorschlags angeschrieben. Es wurde innerhalb von Stunden umgesetzt und ein Update war da, sehr netter Kontakt.

**Developer response:** Vielen lieben Dank für das tolle Review! Ich habe das Feedback sehr gerne umgesetzt! Immer gerne bei mir melden und viel Spass mit der App!

### 4/5 — Good game

*2026-05-27*

I like this app a lot! Definitely a good time waster. I like the different levels of difficulty and the customization as well. My only recommendation is if there can be a “play again” button added after completing the Sudoku! Other than that pretty solid!

**Developer response:** Great idea! „Play again“ will come with the next update, promised!

*UPDATE* Version 2.4 is here with the new Play Again button.

### 5/5 — Fun and Challenging Sudoku

*2026-04-03*

Really fun to play. The puzzles are well designed and the difficulty increases in a nice, balanced way. The expert mode is quite challenging and keeps you thinking, which makes it especially enjoyable for more experienced players. It doesn’t get boring and is great for both quick games and longer sessions.

### 5/5 — Simple yet beautiful

*2026-04-02*

A simple and minimalistic sudoku app perfect for a daily break from everything. From simple to challenging - you get what you want. No ads, no distracting pop ups or annoying interruptions. Plus: you learn skills you need to solve your sudokus. 

10/10 would buy again

### 5/5 — Best Sudoku Experience

*2026-04-01*

Got back into Sudoku puzzles with this one. The constant improvements on the digital Sudoku experience make it a joy to use (something other Sudoku games lost me with. Instead of making core Sudoku enjoyable on a phone or tablet, they added mini games, challenges, and side quests).

The tutorials and techniques documentation will also help you get better at Sudoku. Lots of fun here.
