### 2/5 — Potential

*2026-08-02, version 3.6.0*

This could’ve been a fun game you get stuck in a never-ending add loop. Unplayable

### 1/5 — Don’t waste your time.

*2026-07-19, version 3.6.0*

You get to play 1 round before you are consistently pestered to download another app!

### 2/5 — Too many adds

*2026-07-13, version 3.6.0*

There are too many adds with this game. It feels like you watch almost as many adds as much as you play

### 1/5 — not good

*2026-06-18, version 3.6.0*

its an ad infested game

### 1/5 — Minus 5 stars for behaviour.

*2026-05-10, version 3.6.0*

There’s a game in there somewhere, but it’s a pain to find.

Opened the app… and received an ad before I even played. I then played a game. It’s not much to write home about, but thought I’d try it again another time. I then opened it the following day, and again, before I could play, having just selected the game to play, I received an ad. Brilliant! — Brilliantly poor form. I didn’t play the game. I closed the app.

If you’re too greedy to get the balance right… 1 star. (which is 6 more than behaviour like this deserves).

### 2/5 — More ads than game play

*2026-05-09, version 3.6.0*

I liked the game, but I was spending so much time waiting for ads to finish that I it outweighed the time playing the game. Deleting.

### 1/5 — Zubair ahmed

*2026-04-29, version 3.6.0*

Third class gaming app on every level you may wait for 60 seconds to watch ads

### 1/5 — Holy Ads

*2026-01-06, version 3.6.0*

Actually a fun game, the ads though!!!!!! Too many bleeping ads! Sometimes ads in between levels and they’re long ads. Couldn’t handle that part. Deleted

### 3/5 — Pretty fun*

*2025-12-08, version 3.6.0*

This game is 1 star without an ad blocker. But with Adblock enabled it’s actually pretty fun

### 1/5 — Adds Adds Adds

*2025-11-10, version 3.6.0*

Nothing but adds and once one pops up it doesn’t go away. No way to exit out. Have to close out the whole app and start over. Waste of time.
