### 3/5 — 그럭저럭 할만하지만 개선 사항이 많네요

*2025-08-19, version 2.1*

앱이 최적화가 안되있는듯 반응이 느리며, 숫자를 다 풀고 마지막 숫자를 터치해도 게임이 안끝나는 버그는 여전하고, 난이도 조절이 실패한거 같네요. easy레벨이 무슨  다른 스도쿠의 전문가 수준인듯.

### 3/5 — 3 Strikes

*2025-08-02*

I don’t like that there are 3-strikes and the player can chose to watch an ad or start a new game. This should be an option - not a set standard in a game.

### 2/5 — Game doesn’t recognize the last number

*2025-07-07*

I finished the game and the last number was not recognized  and the clock continues counting. This happened the last 2 games played. Would like to see an option to auto fill the notes.

### 1/5 — Mehr Werbung als Spiel

*2025-07-01*

Hab die Vollversion und sehe enorm viel Werbung. Dabei ist es noch nicht mal gut programmiert. Auf dem iPhone SE sind die Zahlen im Weg und das Spiel kann nicht gewonnen werden. Tut man es doch, weil man es zum Beispiel auf dem iPad spielt, gibt es keine visuelle Kommunikation. Das Spiel muss  neu begonnen werden. Hab versucht mich an den Entwickler zu wenden, der liest die Google Forms scheinbar nicht oder verkauft meine Daten nochmal weiter. Spart euch den Kummer. Sudoku ist klasse, aber nicht mit dieser App

### 3/5 — Ok

*2025-06-24*

It’s ok but a bit buggy. I can’t seem to complete the games once it all finished. Just have to exit and start a new one so stats don’t keep.

### 1/5 — 플레이가 저장되지 않음

*2025-06-22*

쉬움 난이도 24까지 갔는데 1로 돌아감.

### 5/5 — 재밌어요

*2025-06-22, version 2.1*

난이도 적절해요

### 5/5 — Fun

*2025-06-21, version 2.1*

Enjoy your Sudoku

### 1/5 — 게임이 끝나지 않음

*2025-06-20, version 2.1*

마지막 숫자를 넣어도 그대로 남아있고 게임이 끝나지 않음

### 1/5 — 와

*2025-06-20, version 2.1*

난이도 너무 심한거 아닌가? 쉬움 첫 단계부터 깨는게 너무 힘들어서 힌트쓰고 때려 맞춰야 할 수준이다. 스도쿠 앱 여러개 써보며 이런 말도 안되는 수준은 처음이다. 이지 단계 하다가 중간에 숫자 다 채워도 안없어지고 게임이 안끝나는 버그까지 있었다. 와 지워야겠다.

왜 다 깼는데 끝이 안나?

힌트보기 눌러도 반응 없고 먹통되는 경우도 있고

처참한 난이도 조절 필요
