### 4/5 — Minimal and clean but lacks feedback

*2024-12-15*

My only complaint is that the next sudoku just loads immediately after you complete the previous one. I almost thought I accidentally hit the reset button.

### 5/5 — Clean

*2024-07-02*

Very good. No more needed

### 5/5 — This is it

*2022-05-26*

I have downloaded and tried what seems like every sudoku app in the App Store. My search is now over. It’s as simple as it is minimal.

### 5/5 — Beste Umsetzung eines einfachen Vorgangs

*2022-01-14*

Die Funktion Sudoku auf seinen Kern reduziert, in der klaren Vorstellung des Entwicklers. Hier kann ich mich auf das lösen eines Sodokus voll konzentrieren.
Keine Werbung, kein erfassen von Daten, kein Verschwenden von Zeit fürs Aussuchen von unwichtigen Darstellungsmöglichkeiten, keine brüllende Darstellung.
Habe schon nach dem spielen in den ersten Tagen neue Beziehungen der Felder zueinander entdeckt.
Einfach herrlich und fraulich.
Danke

### 5/5 — Very promising

*2020-09-12*

This is by far the nicest looking sudoku app I’ve downloaded, and I’ve tried out dozens. I like that the interface is very clean and minimal. The Apple pencil feature seems very appealing, but is just too buggy as is (understandable, as it is in beta). I wish it was easier to clear notes and toggle note writing on and off. Maybe scribbling over a square could clear it entirely. Very excited to see how this app improves!
