### 5/5 — 완성도 높은 간편한 퍼즐게임

*2021-01-21*

킬링타임으로 딱딱틀딱딱

### 1/5 — 45-60 second ads

*2019-09-04*

After almost every  level that takes less then 30 seconds to solve, there is an ad that lasts at least 45 seconds or longer. I understand you need ads but when there are this many for this amount of time it makes me not want to use this app or any other ones this company has made.

### 5/5 — Every fun game 🎮

*2019-08-27*

Filline is an amazing app. Why because if you finish a level in a amount of moves you get a hint which is much better than watching adds.

### 5/5 — Nice app!

*2019-07-03*

Helps me de stress :)

### 5/5 — 오랜만이 잼나는 퍼즐

*2019-05-17*

그런데 아이패드 좌우로 남는 공간 활용 부탁요
크레이지 모드에서 공간이 남는데 칸이 너무 작음
그리고 아이클라우드 동기화 만들어주세요 ㅠㅠ

### 5/5 — 중독성 오져요,,,

잼나네요
