### 5/5 — 広告少ない

*2024-09-07, version 1.0.3*

時間制限がなく、広告も少なめで楽しく遊べます😆

### 1/5 — Nur 10 Level

*2024-09-04, version 1.0.3*

Und dann wieder von vorne. Hab gespielt bis 900 Level, immer gleich

### 1/5 — FRAUD Bought no ads and it still shows long ads!!

*2024-08-05, version 1.0.3*

I paid for the no ads but it is still interrupting the game with more advertising time than actual play

### 1/5 — Way too many ads

*2024-08-04, version 1.0.3*

Uninstalled this within five minutes of install. Some times double ads between a 15-30 second level… come on. You spend more time watching ads than playing. Would be a fun game if wasn’t filled with ads.

### 2/5 — Gutes Spiel…

*2024-05-30, version 1.0.3*

…ABER ich habe noch nie ein Spiel mit so langen Werbeeinblendungen gesehen! Ständig muss man bis zu 1,5 Minuten lange Werbung ertragen. Das ist zu viel und verdirbt jeden Spaß! Mit kürzeren Werbungen wäre das clevere Spiel wirklich gut!

### 5/5 — ストレスなく

*2024-05-26, version 1.0.3*

簡単だけど楽しいです。今の所時間制限は無さそうです。広告もあまり長くないのでいいです。

### 1/5 — Incredibly easy - no challenge

*2024-05-11, version 1.0.3*

Uninstalled.

### 5/5 — Great game!

*2024-03-28*

Love this game and to remove ads it’s only 2.99, well worth it if you hate ads like I do! I’ve had hours of enjoyment it’s hard to put down it’s so addictive lol love the graphics and sounds too!
Nice to see a good game without the makers taking the p… like some others do!

### 5/5 — Great and value

*2024-03-13, version 1.0.3*

This one of this type of game is one of the best. All level’s achievable up to 108 so far. Occasional freeze up just need restart same if you mess up. Good value for Ad removal. Removes all add except if you go for bonus if you want.

### 5/5 — 👍🏻
