### 4/5 — Sehr schöne Umsetzung des Klassikers

*2026-01-18, version 3.0.7*

Light/Darkmode funktioniert nicht immer zuverlässig, wenn die App im Hintergrund liegt(nicht beendet) und der Wechsel findet statt.

### 4/5 — Kostenlosen Quiz-Varianten sind ok

*2024-05-05, version 3.0.3*

Die kostenlosen Quiz-Varianten sind ok, auf Dauer aber zu einfach und Werbung muss angesehen werden. Wenn es wenigstens Werbung wäre, die nach 10 Sekunden übergangen werden kann. Leider ist der Abo-Preis für die Club-Varianten recht teuer, wenn man etwa nur einmal die Woche spielen würde. Ab und an exzessiv mit Monatsabo spielen und dann ein halbes Jahr später oder noch weiter in der Zukunft, wenn man dann mal überhaupt wieder über die App stolpert, vielleicht wieder.

### 5/5 — Super App!

*2020-02-07, version 1.0.1*

Endlich eine App die auch Chaos-Sudoku anbietet! Hab ewig danach gesucht!

### 5/5 — Einfach top!:)

*2020-02-03, version 1.0*

Tolle App mit schöner Oberfläche. Von ganz einfachen Sudokus, über Herausforderungen, bis zu Sudokus die vielleicht nicht jeder kennt und die einen einige Zeit beschäftigen können. Macht Spaß und ist easy von der Bedienung! Danke dafür:)

### 5/5 — Keine Langeweile mehr

*2020-02-03, version 1.0*

Ich bin begeistert - einfache Bedienung, gut verständlich, geschmackvolle Gestaltung - also insgesamt sehr gut gelungen.

### 5/5 — Macht Spaß !!!

*2020-02-03, version 1.0*

Sehr schönes Spiel! Ich spiele es die ganze Zeit. Es macht viel Spaß und man kann sich damit so gut beschäftigen!

### 5/5 — Pausenfüller mit Suchtfaktor

*2020-02-02, version 1.0*

Überbrückt Wartezeiten wunderbar, sehr intuitive Bedienung. Werbung bei der kostenlosen Version noch völlig im Rahmen. Die zahlreichen neuen Sudokuformen fordern heraus.
