### 5/5 — Best sudoku

*2024-12-09*

I have played the many other sudoku apps but this is by far the best.

### 1/5 — Ads on premium version

*2022-12-28*

I bought the premium version NOT to see ADS. Suddenly there are ads at the top of the screen. Breach of contract!!

### 5/5 — great sudoku app

*2022-10-17*

It does everything you’d want a Sadako app to do.

### 4/5 — Good but could be better

*2021-10-20, version 11.0.5*

The android version is better. In comparison, I find the prominence of the grid lines to be distracting in the iOS version. Please consider changing the look.

### 4/5 — Sudoku💎Rocks💎‼️

*2021-03-31*

The ONLY thing that could improve this app is an overlay screen to take notes on. Thanks for a superb game!

### 5/5 — Good

*2021-01-22*

No complaints

### 1/5 — Nicht wirklich überzeugend

*2020-11-27*

Seit dem Update auf Version 11 läuft die App recht instabil. Bei fertig gelöstem Puzzle bleibt die Anzeige häufig stehen, ohne auf die Auswertung umzuschalten. Schwerer wiegt für mich aber auch weiterhin, dass der größte Teil der präsentierten Sudokus leider nicht wirklich interessant genug sind. Die hier favorisierten sehr symmetrischen Sudokus entsprechen japanischem Geschmack, sind aber doch recht langweilig. Auch auf der schwersten Stufe braucht die Lösung oft nur knapp 2 Minuten; es könnte gern anspruchsvoller sein. Großer Pluspunkt der App allerdings bleibt nach wie vor das vorbildlich durchdachte, ergonomische Layout. Dafür 3 Sterne. 
Nachtrag: Nachdem die App sich aufgehängt hatte und neu aus dem Store geladen werden musste, ist nun der gesamte Verlauf (persönl. Bestzeiten) verschwunden. Das geht leider garnicht und führt zur Abwertung.
Nachtrag 2: Inzwischen wurde mit Version 11.0.5 das Problem behoben, dass gelöste Puzzle nicht ausgewertet wurden. Meine persönlichen Bestzeiten sind wegen schlechter Programmierung der App aber nun einmal verloren und bleiben es.

**Developer response:** Thank you for letting us know. We just released a new version. Please update the app.

### 1/5 — Not right.

*2020-11-26*

Second table m puzzle will not solv due to conflicting numbers

**Developer response:** Hello. Thank you for writing. 

The only way to get "conflicting numbers" in the puzzle is by you putting them there. The initial condition is never wrong.  If you wish for the app to prevent you from entering erroneous values please check the "Flag incorrect values" setting. 

Also, if you want to check your progress at any point, the Validate option under Menu will check your solution and highlight any errors you may have.

### 2/5 — Not enough data

*2020-11-23*

Keep getting that line, and for some reason the puzzles don’t finalize as I complete them.

**Developer response:** Thank you for letting us know. We just released a new version. Please update the app.

### 4/5 — Request Feature

*2020-11-16*

I have been using this for 4 years now. I miss a feature of coloring notes so that I can find easily matching pairs, sword fish etc in notes. Can you please enable?
