## What is Sudoku Club?

Sudoku Club is pen-and-paper-first. It gives you the Sudoku experience you know and love from real paper. Simple, intuitive, direct. Just pick up your pencil and start writing. Distraction-free. Ad-free.

Write to fill in.
Scribble over to erase.
Tap for note-taking.
That’s it.

Choose from 2 different play modes:

### 4/5 — Love the paper like experience

*2025-03-16*

I really love the Apple Pencil support.  It really gives the paper feel. This can be played without the mode/function buttons, and I really like the minimalist design.  Couple of requests:   Please make the grid larger to relieve my old eyes.  It would be nice to have more way to customize the colors and grids.  I hope there is a way to make the boundary of houses stand out more.  Overall great app. Thank you!

### 5/5 — 10/10

*2024-12-18*

Love this game and I love the fact you can write in your numbers with the pencil!

### 3/5 — Fiendish

*2024-10-17*

Really good tricky puzzles.  I found everything a bit small on the screen, it would be great to have a zoom button or just use more of the available screen.  I’ve used ‘Paper Soduko’ a lot and their puzzles seem less challenging but the interface is a bit better

### 4/5 — Love sudoku with apple pencil

*2024-07-06*

I am so happy I found this app! Simple design and nice visuals. If you play with three strikes on it will mistake 6 and 4 and that can be annoying. Sometimes the app will glitch and open as if I’ve never played, but eventually I can get back to my profile and my stats are still there. I would still recommend this app and look forward to more updates!

**Developer response:** Thank you for playing Sudoku Club, I'm glad you like it! And thank you very much for your feedback — it's greatly appreciated. If you could share a screenshot or even a screen recording of the 6/4 ambiguation with App support along with information about your device version and iPadOS version, that could speed up fixing. Thanks again, keep enjoying Sudoku Club!

### 4/5 — Great gameplay, wish you could enlarge grid

*2024-04-29*

Playing with the pencil and ability to tap notes is awesome. Best sudoku with pencil game I’ve played. Wish I could make the grid larger to make the small note numbers easier to see.

### 5/5 — Eine Sudoku-App wie sie sein sollte

*2024-04-21, version 1.2.5*

Genau das was ich gesucht habe. Hab daher auch die Vollversion gekauft. Endlich keine Werbung, mit deutschem Intro zur Bedienung, Notizen können gemacht werden. Die App macht genau das was sie soll und nervt mich nicht mit in-App-Käufen oder Werbung. Apple Pencil oder Kompatibel sollte zum ausfüllen verwendet werden. Wer das sucht wird hier glücklich. Alles in allem genau das was ich gesucht habe.

### 4/5 — Great Sudoku App with Pencil

*2024-03-27*

I really like how convenient it is to complete with minimal work with a pencil. I would like everything to be larger though, so that the numbers and notes are easier to see.

### 4/5 — Great app

*2024-02-25*

I love this app. My only issue is that it consistently mistakes 6 for 4.

### 5/5 — Best sudoku game on App Store

*2023-11-15*

Feels like you just ripped it out of a newspaper! So relaxing and the most organic way to play.

### 5/5 — bestes Sudoku

*2023-11-01, version 1.1*

mit Stift, erkennt die Zahlen und „Schmierzettel“ zum Ausprobieren. Wird nicht langweilig.
