### 5/5 — 최신 퍼즐

*2026-08-14*

몇년째 이 퍼즐게임만 할 정도로 좋아하는 프로그램 입니다. 그런데 최근 실수로 삭제후 다운로드 받았는데 최신퍼즐 다운이 안되는것 같아요. 현 버전은 1.386입니다.사이즈별로 최신퍼즐이 어디까지 추가되어있습니까? 참고로 <황제의 탄생-원로원>까지가 맞습니까?

### 5/5 — 앞으로도 잘 부탁드립니다

*2026-06-11*

진짜 예전 갤럭시 쓸 때부터 아이폰으로 넘어오기까지 다시 깔고 얼마나 했는지 모르겠어요 조작이 제일 쉽고 편하게 할 수 있어서 좋아요 종류도 많아서 앞으로도 쭈욱 하고 싶어요 !! 좋은 게임 감사합니다

### 5/5 — Love this game

*2026-04-08*

I’ve been playing this game on and off for years now, and I keep coming back to it. I really like the v-pad mode. Something about clicking square by square is deeply satisfying. They keep adding more puzzles and if I ever manage to catch up to all of them, I go back and challenge myself to get 3 stars on the ones I missed. I like the interface and the thoughtful UI touches, like adding a star on the game set if you’ve 3-starred every game in the set.

### 5/5 — Fun, challenging & not full of ads!

*2026-01-16*

I’ve been playing this for nearly a decade & still prefer to most newer fancy nonogram puzzles.

### 5/5 — Love this game

*2025-08-26*

I think I’ve deleted and downloaded this game three or four times now to be able to redo all the puzzles. Would love more, but there are soooo many available ones to play. I’ve been playing this game for 5+ years and am completely obsessed. Thank you!

### 4/5 — 난이도 예측불가!

*2025-05-02*

오랫동안 하고 있는 게임인데, 한가지 아쉬운건 게임을 완성하기 전에는 해당 게임의 난이도를 알 수 없다는거에요 ㅠ
여러 로직게임을 받아봤지만 일정 수준 이상 플레이 되지 않는 것도 잇고 그렇던데 이건 제한없이 다 할 수 있어서 좋아요. 패드로 하니까 화면도 커서 넘 좋더라구요. 진짜 딱 하나 아쉬운건 어떤 문제는 너무 쉽고 어떤 문제는 너무 어려운데 그걸 골라서 풀 수 없다는 점 ㅠㅠ 미리 알 수 있게 해주세요~

### 5/5 — 오류발견!

*2025-03-27*

안녕하세요 10년 넘게 즐기고 있는 유저입니다ㅎㅎ 저만 그런건지는 모르겟는데 안데르센동화-성녕팔이소녀2에 오류가 있는것 같은데 확인부탁드려요
재밌는 게임 만들어주셔서 너무 감사해요 덕분에 오랜기간동안 잘 즐기고 있습니다!

### 5/5 — My favorite game for almost 10 years now

*2025-01-26*

I love this game with my whole heart. I love every puzzle and I love how relaxing it is to play.

### 5/5 — So addicting!

*2024-10-27, version 1.357*

Just the best game ever

### 5/5 — love

*2024-07-29, version 1.352*
