### 5/5 — Choose this

*2026-08-14*

I enjoy games that make me think. I love this one. And I have never ever had a problem with the app. I especially love being able to play it off line.

### 5/5 — Love this game!

*2024-07-25*

I love this game but I wish there were more free puzzles.

### 1/5 — Terrible method to mark the squares

*2023-11-16, version 3.2.1*

A terrible method to mark the squares!

### 5/5 — Creatively Challenging!

*2021-11-18, version 3.2.1*

Great for beginners and pros. You can even create your own Nonogram!

### 5/5 — Favoriten fehlen

*2020-03-22, version 3.2.1*

Die App ist super. Besonders die Community Funktion gefällt mir besonders gut. Es besteht da aber leider keine Möglichkeit, Favoriten zu setzen. Das wäre super. Denn die Bewertungen stimmen nicht immer mit dem Schwierigkeitsgrad der Rätsel überein..

### 4/5 — Beste Nonogramm-App

*2019-03-26, version 3.1.12*

Diese App begleitet mich seit Jahren und ist im App-Store die beste App für diese Art von Logik-Rätseln.
Andere Apps sind mir zu bunt, unübersichtlich und kompliziert zu bedienen.
In dieser App wird einem der Einstieg mit Erläuterung erklärt und man kann sich zunächst über schwarz-weiß an die bunten Rätsel heranarbeiten. 
Ich habe mir bereits jede Menge der Pakete gekauft, da diese auch wunderbar in unterschiedliche Größen und Schwierigkeitsstufen gegliedert sind.
Einen Punkt Abzug dafür, dass seit Jahren keine Aktualisierungen mehr kommen. Ich würde mir mehr bunte Rätsel in Größe M wünschen. Habe fast alle Pakete gespielt und teilweise wieder neu gestartet.

### 2/5 — Cursor

*2018-10-23*

The playing cursor is annoying. So much less convenient than just tapping and swiping like other apps. Wish there was an option to turn it off. Quit after 3 puzzles

### 5/5 — Ios12卡頓-

*2018-09-25, version 3.1.12*

昨天更新Ios 12之後遊戲變得卡頓，卡到無法進行，希望改善，其他遊戲、app皆正常無此問題
更新速度超快，有誠意，會花錢贊助

### 5/5 — Love it, could use some UI help

*2018-05-12*

Great game, love the games with color - mega cool. 

The UI is not ideal. I wish when I swiped over previously filled out squares, that it wouldn’t overwrite them. Instead it should just skip them. 

Finally, would love a “dark mode” - black background, etc. 

Keep up the great work!

### 4/5 — Great game but needs a tweak

*2018-03-22, version 3.1.7*

I love nonograms and this is one of the best. I would recommend a cross out or fade of the numbers you have completed.
